Glossary of Vessel Types

Anchor handling towing supply (“AHTS”) vessels are used primarily to support offshore drilling activities in the towing, positioning and mooring of drilling rigs and other marine equipment. AHTS vessels are also used to transport supplies and equipment from shore bases to offshore drilling rigs, platforms and other installations. The defining characteristics of AHTS vessels are horsepower (“bhp”), size of winch in terms of “line pull” and wire storage capacity. Offshore Marine Services’ fleet of AHTS vessels has varying capabilities and supports offshore mooring activities in water depths ranging from 300 to 8,000 feet. Most modern AHTS vessels are equipped with dynamic positioning (“DP”) systems that enable them to maintain a fixed position in close proximity to a rig without the use of tie-up lines.

Crew boats are used primarily to move cargo and personnel to and from offshore drilling rigs, platforms and other installations. Historically, crew boats transported people and were also used to deliver “light” cargo such as personal effects, small machinery and small quantities of fuel and water. These boats also served as field stand-by vessels, moving personnel between platforms and providing emergency stand-by services. Crew boats built prior to 1990 are generally 100 to 130 feet in length and are capable of 20 knots speed in light conditions and calm seas. Vessels built since 1998, also referred to as Fast Support Vessels (“FSVs”), range from 130 to 200 feet in length and are capable of speeds between 25 and 35 knots. Modern FSVs have enhanced cargo carrying capacities enabling them to support both drilling operations and production services. Vessels supporting deep water drilling are usually equipped with DP capabilities, ride control systems and firefighting equipment.

Mini-supply vessels are approximately 145 to 165 feet in length and typically carry deck cargo, liquid mud, methanol, diesel fuel and water. These vessels are typically used to support construction projects, maintenance work, certain drilling support activities and production support.

Standby safety vessels typically remain on location proximate to offshore rigs and production facilities to respond to emergencies. These vessels carry special equipment to rescue personnel and are equipped to provide first aid and shelter. These vessels sometimes perform a dual role, also functioning as supply vessels.

Supply vessels and towing supply vessels are generally more than 200 feet in length and are used to deliver cargo to rigs and platforms where drilling and work-over activity is underway or to support construction work by delivering pipe to vessels performing underwater installations. Supply vessels are distinguished from other vessels by the total carrying capacity (expressed as deadweight: “dwt”), available area of clear deck space, below-deck capacity for storage of mud and cement used in the drilling process and tank storage for water and fuel oil. The ability to hold station in open water and moderately rough seas is a key factor in differentiating supply vessels. To improve station keeping ability, certain supply vessels have DP capabilities. Towing supply vessels perform similar cargo delivery functions to those handled by supply vessels. They are, however, equipped with more powerful engines (4,000 – 8,000 bhp) and winches, giving them the added capability to perform general towing functions, buoy setting and limited anchor handling work.

Specialty includes anchor handling tugs, lift boats, accommodation, line handling and other vessels. These vessels generally have specialized features adapting them to specific applications including offshore maintenance and construction services, freight hauling services and accommodation services.

Markets

The demand for vessels is affected by the level of offshore exploration and drilling activities, which in turn is influenced by a number of factors including:

• expectations as to future oil and gas commodity prices

• customer assessments of offshore drilling prospects compared with land-based opportunities

• customer assessments of cost, geological opportunity and political stability in host countries

• worldwide demand for oil and natural gas

4

• the ability of The Organization of Petroleum Exporting Countries (“OPEC”) to set and maintain production levels and pricing

• the level of production of non-OPEC countries

• the relative exchange rates for the U.S. dollar

• various United States and international government policies regarding exploration and development of oil and gas reserves

Offshore Marine Services operates vessels in six principal geographic regions. From time to time, vessels are relocated between these regions to meet customer demand for equipment. The table below sets forth vessel types by geographic market as of December 31 for the indicated years. Offshore Marine Services sometimes participates in joint venture arrangements in certain geographical locations in order to enhance marketing capabilities and facilitate operations in certain foreign markets. This allows for the expansion of Offshore Marine Services’ fleet and operations while diversifying risks and reducing capital outlays associated with such expansion.

United States. As of December 31, 2010, 57 vessels were operating in the U.S. Gulf of Mexico, including 34 owned, 17 leased-in, three joint ventured and three pooled. Offshore Marine Services’ expertise in this market is deepwater anchor handling with its fleet of AHTS vessels, and exploration and production support with its fleet of crew and mini-supply vessels. Over the last few years, the market has split between the traditional shallow water shelf activity and the developing deepwater market. The shelf market is highly price sensitive and quickly affected by movements in commodity prices. Customers in the deepwater market place greater emphasis on vessel specifications and features in addition to price.

Africa, primarily West Africa. As of December 31, 2010, 21 vessels were operating in West Africa, including 13 owned, three leased-in, three joint ventured and two managed. Offshore Marine Services operates primarily in Angola and Ghana, servicing large-scale, multi-year projects for major oil companies. The other vessels in this region operate from ports in the Republic of the Congo, Gabon, Equatorial Guinea and South Africa.

Middle East. As of December 31, 2010, 20 vessels were operating in the Middle East region, including 16 owned, one leased-in, two joint ventured and one managed. Offshore Marine Services’ vessels operating in this area generally support activities in countries along the Arabian Gulf and Arabian Sea, including the United Arab Emirates, Qatar, Egypt and India.

Mexico, Central and South America. As of December 31, 2010, 23 vessels were operating in Mexico, Central and South America, including twelve owned, one joint ventured and ten managed. Offshore Marine Services’ primary markets in this region are Brazil and Mexico.

United Kingdom, primarily North Sea. As of December 31, 2010, 26 vessels were operating in the North Sea, including 25 owned and one joint ventured. The North Sea fleet provides standby safety and supply services. Demand in the North Sea market for standby services developed in 1991 after the United Kingdom passed legislation requiring offshore operators to maintain higher specification standby safety vessels. The legislation requires a vessel to “stand by” to provide a means of evacuation and rescue for platform and rig personnel in the event of an emergency at an offshore installation.

Asia. As of December 31, 2010, seven vessels were operating in Asia, including four owned, two joint ventured and one managed. Offshore Marine Services’ vessels operating in this area generally support exploration programs. To date, Offshore Marine Services’ largest markets in this area have been Vietnam and Indonesia.

Customers and Contractual Arrangements

The Offshore Marine Services segment earns revenues primarily from the time charter and bareboat charter of vessels to customers based upon daily rates of hire. Under a time charter, Offshore Marine Services provides a vessel to a customer and is responsible for all operating expenses, typically excluding fuel. Under a bareboat charter, Offshore Marine Services provides a vessel to the customer and the customer assumes responsibility for all operating expenses and assumes all risk of operation. Vessel charters may range from several days to several years. In the U.S. Gulf of Mexico, time charter durations and rates are typically established in the context of master service agreements that govern the terms and conditions of charter.

Offshore Marine Services’ principal customers are major integrated oil companies, large independent oil and gas exploration and production companies and emerging independent companies. Consolidation of oil and gas companies through mergers and acquisitions over the past several years has reduced Offshore Marine Services’ customer base. In 2010, no single customer was responsible for 10% or more of consolidated operating revenues. The ten largest customers of Offshore Marine Services accounted for approximately 60% of Offshore Marine Services’ operating revenues. The loss of one or a few of these customers could have a material adverse effect on Offshore Marine Services’ results of operations.

Competitive Conditions

Each of the markets in which Offshore Marine Services operates is highly competitive. The most important competitive factors are pricing and the availability and specifications of equipment to fit customer requirements. Other important factors include service, reputation, flag preference, local marine operating conditions, the ability to provide and maintain logistical support given the complexity of a project and the cost of moving equipment from one geographical location to another.

Offshore Marine Services has numerous competitors in each of the geographical regions in which it operates, ranging from international companies that operate in many regions to smaller local companies that typically concentrate their activities in one specific region.

Risks of Foreign Operations

For the years ended December 31, 2010, 2009 and 2008, 53%, 63% and 52%, respectively, of Offshore Marine Services’ operating revenues were derived from foreign operations.

Foreign operations are subject to inherent risks, including, among others, political instability, asset seizures, blockades, blacklisting, nationalization of assets, terrorist attacks, piracy, kidnapping, fluctuating currency values, hard currency shortages, controls on currency exchange, the repatriation of income or capital, import-export quotas and other forms of public and governmental regulation, all of which are beyond the control of Offshore Marine Services. It is difficult to predict whether or when any of these conditions or events may develop in the future. The occurrence of any one or more of these conditions or events could have a material adverse effect on Offshore Marine Services’ financial position and its results of operations.

Aviation Services

Business

Aviation Services is primarily engaged in transportation services to the offshore oil and gas exploration, development and production industry, international aircraft leasing, transportation and customer-owned aircraft management services to hospitals (“Air Medical Services”) and flightseeing tours in Alaska. In addition, Aviation Services sells fuel and provides other services to corporate aircraft at its fixed base operation (“FBO”) at Ted Stevens Anchorage International Airport. It also provides aircraft and flight crews under contracts in support of fire-fighting, provides flight training services and provides emergency response search and rescue services. Aviation Services operates a Federal Aviation Administration (“FAA”) approved maintenance repair station in Lake Charles, Louisiana. Aviation Services contributed 9%, 14% and 15% of consolidated operating revenues in 2010, 2009 and 2008, respectively.

(1) Excludes two and three helicopters removed from service as of December 31, 2010 and 2009, respectively. During 2010, two helicopters were removed from service and disassembled for spare parts. Another helicopter that was removed from service as of December 31, 2009 was also disassembled for spare parts in 2010.

(2) Excludes three helicopters removed from service as of December 31, 2010 and 2009.

In typical configurations, Light helicopters are single or twin engine helicopters with a passenger capacity between five and seven, Medium helicopters are twin engine helicopters with a passenger capacity of up to 13 and Heavy helicopters are twin engine helicopters with a passenger capacity of up to 19.

Aviation Services has a 49% interest in an international sales, marketing and manufacturing organization focusing on after-market helicopter accessories.

Aviation Services has a 50% interest in a joint venture that provides instruction and flight simulator training to outside customers and Aviation Services’ employees.

Aviation Services has a 50% interest in a joint venture based in Spain that provides aviation transportation services.

Markets

Aviation Services’ current principal markets for its transportation and search and rescue services supporting the offshore oil and gas exploration, development and production industry are in the U.S. Gulf of Mexico and

8

Alaska. In the U.S. Gulf of Mexico, the customers and locations are similar to those serviced by Offshore Marine Services and its market opportunities are subject to the same cycles and pressures as described in Item 1. Business—Offshore Marine Services—Markets. Other helicopter services to the oil and mining industries in Alaska are provided on a contract or charter basis from bases in Valdez, Anchorage, the Kenai area and Deadhorse.

Aviation Services also leases helicopters, primarily to foreign operators in Brazil, Europe and Southeast Asia. Air Medical Services operations are primarily in the northeastern United States, Florida and Tennessee. Flightseeing services in Alaska are operated out of Juneau and from areas near Denali National Park.

Seasonality

A significant portion of Aviation Services’ operating revenues and profits related to oil and gas industry activity is dependent on actual flight hours. The fall and winter months have fewer hours of daylight and flight hours are generally lower at these times. In addition, prolonged periods of adverse weather in the fall and winter months coupled with the effect of fewer hours of daylight can adversely impact operating results. In general, the months of December through February in the U.S. Gulf of Mexico and October through April in Alaska have more days of adverse weather conditions than the other months of the year. In the U.S. Gulf of Mexico, June through November is tropical storm season. During tropical storms, Aviation Services is unable to operate in the area of a storm although flight activity may increase immediately prior to and after storms due to the evacuation and return of offshore workers. The Alaska flightseeing operation is also seasonal with activity generally occurring from late May until early September.

Aviation Services charters its helicopters to utility and oil and gas customers primarily through master service agreements, term contracts, subscription agreements, day-to-day charter arrangements and leases. Master service agreements require incremental payments above a fixed rental fee based upon flight hours flown, have fixed terms ranging from one month to five years and generally are cancelable upon 30 days notice. Subscription agreements are priced and carry terms similar to master service agreements, and are for the provision of offshore emergency search and rescue services. Day-to-day charter arrangements call for a combination of a daily fixed rental fee plus a charge based on hours flown or an hourly rate. Leases can be either “dry”, providing only the equipment, or “wet”, providing equipment, insurance and personnel. The rate structure, as it applies to Aviation Services’ utility and oil and gas contracts, typically contains terms that limit its exposure to increases in fuel costs over a pre-agreed level. Fuel costs in excess of these levels are passed through to customers. With respect to flightseeing aircraft, block space is allocated to cruise lines and seats are sold directly to customers. Other markets for Aviation Services include international oil and gas industry support activities, agricultural support and general aviation activities.

Air Medical Services are provided under contracts with hospitals that typically include either a fixed monthly and hourly rate structure, similar to oil and gas, or a fee per completed flight. Most contracts with hospitals are longer term, but offer either party the ability to terminate with less than six months notice. Aviation Services operates some air medical contracts pursuant to which it collects a fee per flight, either from a hospital or an insurance company.

Aviation Services’ FBO in Alaska sells fuel and other services to a diverse group of general aviation companies and large corporations on an ad hoc basis. In addition, the FBO leases hangar space and provides fueling services for transient aircraft and the aviation assets of local companies.

Aviation Services’ principal customers in the U.S. Gulf of Mexico are oil companies of varying sizes and the U.S. government. In Alaska, its principal customers for helicopter services are oil and mineral companies and cruise line passengers.

In 2010, no single customer was responsible for 10% or more of consolidated operating revenues. The ten largest customers of Aviation Services accounted for approximately 59% of Aviation Services’ operating revenues. The loss of one or a few of its customers could have a material adverse effect on Aviation Services’ results of operations.

Competitive Conditions

The helicopter transportation business is highly competitive. Aviation Services is one of the largest helicopter companies operating in the U.S. Gulf of Mexico and one of the largest operating in Alaska. In the U.S. Gulf of Mexico, there are three major competitors: PHI, Inc., Bristow Group, Inc. and Rotorcraft Leasing Company LLC. In addition, several customers in the U.S. Gulf of Mexico operate their own helicopter fleets. In Air Medical Services, there are several major competitors with larger fleets than Aviation Services. In most instances, an operator must have an acceptable safety record, demonstrated reliability and suitable equipment to bid for work. Among bidders meeting these criteria, customers typically make their final choice based on price and aircraft preference.

Risks of Foreign Operations

Aviation Services operates worldwide. For the years ended December 31, 2010, 2009 and 2008, 24%, 15% and 10%, respectively, of Aviation Services’ operating revenues were derived from its foreign operations.

Foreign operations are subject to inherent risks, including, among others, political instability, asset seizures, blockades, blacklisting, nationalization of assets, terrorist attacks, piracy, kidnapping, fluctuating currency values, hard currency shortages, controls on currency exchange, the repatriation of income or capital, import-export quotas and other forms of public and governmental regulation, all of which are beyond the control of Aviation Services. It is difficult to predict whether or when any of these conditions or events may develop in the future. The occurrence of any one or more of these conditions or events could have a material adverse effect on Aviation Services’ financial condition and its results of operations.

Inland River Services

Business

Inland River Services owns, operates, invests in and markets inland river transportation equipment. The Company believes it operates one of the industry’s newest fleets of dry cargo and liquid tank barges transporting agricultural and industrial commodities, and chemical and petrochemical products on the U.S. Inland River Waterways, primarily the Mississippi River, Illinois River, Tennessee River, Ohio River and their tributaries, and the Gulf Intracoastal Waterways. Inland River Services also owns towboats used for moving barges, fleeting operations and deck barges. It also manages barges for third parties. Inland River Services contributed 6%, 9% and 9% of consolidated operating revenues in 2010, 2009 and 2008, respectively.

11

Inland barges are unmanned and are moved on the U.S. Inland River Waterways by towboats. The combination of a towboat and dry cargo barges is commonly referred to as a “tow.” The Inland River Services dry cargo fleet consists of hopper barges, which can be open for the transport of commodities that are not sensitive to water such as coal, aggregate and scrap, or covered for the transport of water sensitive products, such as grain, ores, alloys, cements and fertilizer. Each dry cargo barge in the Inland River Services’ fleet is capable of transporting approximately 1,500 to 2,000 tons (1,350 to 1,800 metric tons) of cargo. The carrying capacity of a barge at any particular time is determined by water depth in the river channels and hull size of the barge. Adverse river conditions, such as high water resulting from excessive rainfall or low water caused by drought, can also impact operations by limiting the speed at which tows travel the U.S. Inland River Waterways, the number of barges included in tows and the quantity of cargo that is loaded in the barges.

Typical dry cargo voyage activity requires shifting a clean, empty barge from a fleeting location to a loading facility. The barge is then moved from the loading location and assembled into a tow before proceeding to its next destination. After unloading, it is shifted to a fleeting area for cleaning and repair, if needed, before being moved again into a load position. Typically, grain cargos move southbound and non-grain cargos move northbound. Generally, Inland River Services attempts to coordinate the logistical match-up of northbound and southbound movements of cargo to minimize repositioning costs.

Inland River Services’ fleet of 10,000 barrel liquid tank barges transports liquid bulk commodities such as lube oils, solvents and glycols. The operations of these barges are similar to those of the dry cargo barges described above. Inland River Services’ fleet of 30,000 barrel liquid tank barges transports refined petroleum products and black oil products and are normally chartered-out as “unit tows” consisting of two to three barges along with a towboat working in patterns prescribed by the customer. Inland River Services is responsible for providing manpower for the towboats working in such operations.

In addition to its primary barge business, Inland River Services:

• Owns a “fleeting operation,” which is a staging area for grouping barges in preparation for movements up and down the river and a holding area for barges waiting to load and unload cargo. This fleeting operation is managed by a third party.

• Owns a tank farm and handling facility in Sauget, Illinois. The facility is multi-modal, supporting truck, rail, unit trains and barges, and commenced operations in May 2008.

• Provides a broad range of services including machine shop, gear and engine repairs, repair of barges and towboats at convenient drydocking locations strategically located on the U.S. Inland River Waterways, and a 24-hour shore side tankering business.

• Has a 50% interest in a joint venture that operates a grain and fertilizer storage and handling facility in McLeansboro, Illinois.

• Has a 50% interest in a joint venture with a third party in South America that, as of December 31, 2010, operated nine towboats and 172 dry cargo barges on the Parana-Paraguay Rivers along with a transshipment terminal at the Port of Ibicuy, Argentina.

• Has a 50% interest in a joint venture that operates six inland river towboats on the U.S. Inland River Waterways.

• Has a 50% interest in a joint venture that operates a dry cargo vessel in South America.

Markets

The market for Inland River Services is driven by supply and demand economics, which impacts prices, margins achieved and utilization of Inland River Services’ assets. The relationship between supply and demand reflects many factors, including:

• the level of domestic and international production of the basic agricultural products to be transported (in particular, the yield from grain harvests)

12

• the level of domestic and international consumption of agricultural products and the effect of these levels on the volumes of products that are physically moved into the export markets

• domestic and worldwide demand for iron ore, steel, steel by-products, coal, ethanol, petroleum and other bulk commodities

• strength or weakness of the U.S. dollar

• the cost of ocean freight and the cost of fuel

Within the United States, other local factors also have an effect on pricing and margins, including:

• the supply of barges available to move the products

• the cost of qualified wheelhouse personnel

• the ability to position the barges to maximize efficiencies and utility in moving cargos both northbound and southbound

• the cost of alternative forms of transportation (primarily rail)

• general operating logistics on the river network including size and operating status of locks and dams

• the effect of river levels on the loading capacities of the barges in terms of draft restrictions

• regulations

Seasonality

During harsh winters the upper Mississippi River usually closes to barge traffic from mid-December to mid-March. Ice often hinders the navigation of barge traffic on the mid-Mississippi River, the Illinois River and the upper Ohio River during the same period. The volume of grain transported from the Midwest to the Gulf of Mexico, which is primarily for export, is greatest during the harvest season from mid-August through late November. The harvest season is particularly significant because pricing tends to peak during these months in response to higher demand for equipment.

Customers and Contractual Arrangements

The principal customers for Inland River Services are major agricultural companies, major integrated oil companies and industrial companies. In 2010, no single customer was responsible for 10% or more of consolidated operating revenues. The ten largest customers of Inland River Services accounted for approximately 71% of Inland River Services’ revenues in 2010. The loss of one or a few of its customers would be unlikely to have a material adverse effect on Inland River Services’ results of operations.

Most of Inland River Services’ dry cargo barges are employed under contracts of affreightment that can vary in duration, ranging from one voyage to several years. For longer term contracts, base rates may be adjusted in response to changes in fuel prices and operating expenses. Some longer term contracts provide for the transport of a minimum number of tons of cargo or specific transportation requirements for a particular customer. Some barges are bareboat chartered-out to third parties for a fixed payment of hire per day for the duration of the charter. These contracts tend to be longer, ranging in term from one to five years.

Inland River Services generally charges a price per ton for point to point transportation of dry bulk commodities. Customers are permitted a specified number of days to load and discharge the cargo and thereafter pay a per diem demurrage rate for extra time. From time to time, dry cargo barges may be used for storage for a period prior to delivery.

13

Inland River Services’ 10,000 barrel liquid tank barges are either chartered-out on term contracts ranging from one to five years or marketed on the spot market.

Inland River Services’ 30,000 barrel liquid tank barges are marketed primarily as unit tows under term contracts ranging from one to five years.

Inland River Services’ tank farm and handling facility is marketed on a tariff system driven by throughput volume.

Competitive Conditions

Generally, Inland River Services believes the primary barriers to effective competitive entry into the U.S. Inland River Waterways markets are the complexity of operations, the consolidation of the inland river towing industry and the difficulty in assembling a large enough fleet and an experienced staff to execute voyages efficiently and re-position barges effectively to optimize their use. The primary competitive factors among established operators are price, availability and reliability of barges and equipment of a suitable type and condition for a specific cargo.

Inland River Services’ main competitors are other barge lines. Railroads and liquid pipelines also compete for traffic that might otherwise move on the U.S. Inland River Waterways.

The Company believes that 67% of the domestic dry cargo fleet is controlled by five companies and 60% of the domestic liquid barge industry fleet is controlled by five companies.

Risks of Foreign Operations

Inland River Services foreign operations primarily consist of its joint ventures operating in foreign jurisdictions.

Foreign operations are subject to inherent risks, including, among others, political instability, asset seizures, blockades, blacklisting, nationalization of assets, terrorist attacks, piracy, kidnapping, fluctuating currency values, hard currency shortages, controls on currency exchange, the repatriation of income or capital, import-export quotas and other forms of public and governmental regulation, all of which are beyond the control of Inland River Services. It is difficult to predict whether or when any of these conditions or events may develop in the future. The occurrence of any one or more of these conditions or events could have a material adverse effect on Inland River Services’ financial position and its results of operations.

Marine Transportation Services

Business

Marine Transportation Services fleet consists of eight U.S.-flag product tankers, of which six are owned and two are leased, providing marine transportation services for petroleum products and chemicals moving in the U.S. domestic coastwise trade. Marine Transportation Services contributed 3%, 5% and 7% of consolidated operating revenues in 2010, 2009 and 2008, respectively.

Equipment and Services

The Oil Pollution Act of 1990 (“OPA 90”) prohibits vessels without double-hulls from transporting crude oil and petroleum products in U.S. coastwise transportation after certain dates based on the age and carrying capacity of the vessel. In addition, single-hulled vessels will be prohibited from transporting petroleum products in most international markets under a phase-out schedule established by the International Maritime Organization (“IMO”). The table below sets forth the Marine Transportation Services’ fleet as of December 31, 2010.

Markets

Petroleum Product Transportation. In the domestic energy trade, oceangoing vessels transport fuel and other petroleum products primarily from refineries and storage facilities along the coast of the U.S. Gulf of Mexico to utilities, waterfront industrial facilities and distribution facilities along the U.S. Gulf of Mexico, and the U.S. Atlantic and Pacific coasts. The number of U.S.-flag oceangoing vessels eligible to participate in the U.S. domestic trade and capable of transporting fuel or petroleum products has fluctuated in recent years as vessels have reached the end of their useful lives or have been retired due to OPA 90 requirements and newbuilds are placed into service.

Chemical Transportation. In the U.S. domestic coastwise chemical transportation trade, vessels carry chemicals, primarily from chemical manufacturing plants and storage facilities along the coast of the U.S. Gulf of Mexico to industrial users in and around U.S. Atlantic and Pacific coast ports. The chemicals transported consist primarily of caustic soda, paraxylene, alkylates, toluene and lubricating oils. Some of the chemicals must be carried in vessels with specially coated or stainless steel cargo tanks and many of them are sensitive to contamination and require special cargo-handling equipment.

Customers and Contractual Arrangements

The primary purchasers of petroleum product transportation services are multinational oil and gas companies, refining companies, oil trading companies and large industrial consumers of fuel with waterfront facilities. The primary purchasers of chemical transportation services are chemical and oil companies. Both services are generally contracted on the basis of short-term or long-term time charters, voyage charters, and contracts of affreightment or other transportation agreements tailored to the shipper’s requirements. In 2010, no single customer was responsible for 10% or more of consolidated operating revenues. The ten largest customers of Marine Transportation Services accounted for approximately 100% of its operating revenues. The loss of one or a few of these customers could have a material adverse effect on Marine Transportation Services’ results of operations.

15

Under a time charter, Marine Transportation Services provides a vessel to a customer and is responsible for all operating expenses, typically excluding fuel and port charges. Under a bareboat charter, Marine Transportation Services provides a vessel to a customer and the customer assumes responsibility for all operating expenses and assumes all risk of operation. Vessel charters may range from several days to several years. Voyage contracts are contracts to carry cargos on a single voyage basis regardless of time to complete. Contracts of affreightment are contracts for cargos that are committed on a multi-voyage basis for various periods of time, with minimum and maximum cargo tonnages specified over the period at a fixed or escalating rate per ton.

Competitive Conditions

The markets in which the Marine Transportation Services fleet operates are highly competitive. Primary direct competitors are other operators of U.S.-flag ocean-going tank vessels and chemical carriers, operators of articulated tug and barge units and operators of refined product pipelines. The U.S. “Jones Act” shipping market is a trade that is not available to foreign-based competition. The most important competitive factors are pricing, vessel age and vessel availability to fit customer requirements as well as customer preference for double-hull vessels even though single hull vessels are still eligible to trade.

Environmental Services

Business

Environmental Services primarily provides emergency preparedness and response services to oil, chemical, industrial and marine transportation clients, and government agencies in the United States and abroad. In the United States, these services are generally rendered to those clients who store, transport, produce or handle petroleum and certain non-petroleum oils that are subject to the provisions of OPA 90 and various other federal, state and municipal regulations. Internationally, these services may be required by legislation and regulation of countries, international maritime conventions and environmental covenants placed on clients by their lending institutions. To a lesser extent, Environmental Services provides emergency preparedness and response services to governmental agencies arising from natural disasters and homeland security issues such as debris removal monitoring, public assistance projects, bio-terrorism, pandemic influenza and port security. Environmental Services also provides other services to oil, chemical, industrial and government clients including hazardous waste management, industrial and marine cleaning, salvage support, petroleum storage tank removal, pipeline repair and site remediation services. Business is conducted primarily through the Company’s wholly owned subsidiaries: National Response Corporation (“NRC”), O’Brien’s Response Management Inc. and SEACOR Environmental Services International Limited. Environmental Services contributed 33%, 8% and 10% of consolidated operating revenues in 2010, 2009 and 2008, respectively.

Products and Services

Environmental Services employs trained personnel and maintains specialized equipment positioned in the United States and in certain locations outside the United States to respond to oil and chemical spills, other emergencies and customer projects. A fleet of specialized vessels and barges outfitted with oil spill equipment is positioned on the East, Gulf and West coasts of the United States as well as in the Caribbean and Hawaii. Oil and chemical spill response equipment are also stationed in certain international locations in Africa, the Caspian and Black Sea Region, the Far East and the Middle East. Environmental Services has established a network of approximately 180 independent oil spill response contractors that may assist it by providing equipment and personnel.

Environmental Services offers retainer contracts to the maritime community, such as operators of tank and non-tank vessels and chemical carriers, and to owners of facilities, such as refineries, pipelines, exploration and production platforms, power plants and storage tank and transportation terminals. Retainer contracts provide customers with access to professional response management and specialized equipment necessary to respond to an oil or chemical spill emergency and facilitate compliance with regulations such as OPA 90.

16

Environmental Services provides a range of prevention, business continuity, crisis communication, software, media, safety and security consultancy, and training services around the world to assist oil, chemical, industrial, marine transportation, financial services and government customers in the prevention of, and response to, an extensive variety of environmental emergencies on both a retained and stand-alone basis. Environmental Services assists customers in the selection and training of personnel in the use of environmental equipment and products. In addition, Environmental Services provides a service to state, county and other local government agencies assisting them with claim reimbursement from the federal government, through agencies such as the Federal Emergency Management Agency (“FEMA”) and the Federal Highway Administration. Furthermore, it provides oversight of clean-up and debris management required after hurricanes, floods and other natural disasters.

Environmental Services provides industrial and remediation services to oil, chemical, industrial and government clients. These services include hazardous waste management, industrial and marine cleaning, salvage support, petroleum storage tank removal, pipeline repair and site remediation services.

Markets

The market for contractual oil spill preparedness, response and other related training and consulting services in the United States resulted from the enactment of OPA 90. OPA 90 and several subsequent regulations promulgated by the Department of Transportation, Environmental Protection Agency (“EPA”), the Bureau of Ocean Energy Management, Regulation and Enforcement (“BOEMRE”), a division of the U.S. Department of Interior, and the U.S. Coast Guard (“USCG”) require that all tank vessels operating within the 200-mile Exclusive Economic Zone of the United States and all facilities and pipelines handling oil that could have a spill affecting the navigable waters of the United States develop plans to respond to a “worst case” oil spill and ensure by contract or other approved means the ability to respond to such a spill.

The market for vessel security assessments, security plans, security training and exercises and other related services is for clients required to comply with the Maritime Transportation Security Act of 2002. Homeland Security services are marketed to government agencies to assist with efforts to improve emergency preparedness and response capabilities.

In the international market for oil spill response services, Environmental Services seeks to develop opportunities with governments, other agencies and international oil and gas exploration and production companies to establish and operate the necessary response capability. International crisis management and business continuity services focus on middle and senior management and are marketed to a broad range of industry sectors such as oil and gas, chemical, financial services, transportation and other industries.

The market for government services in the United States includes federal, state, county, city, and other subdivisions and agencies. Services are typically provided in association with specific funding sources, such as FEMA reimbursement, Homeland Security Grants, municipal budgets and other agency funding.

Customers and Contractual Arrangements

Environmental Services offers its services primarily to the domestic and international shipping community, major oil companies, independent exploration and production companies, pipeline and transportation companies, power generating operators, industrial companies, airports and state and local government agencies. Services are provided pursuant to contracts generally ranging from one month to ten years. In 2010, one Environmental Services’ customer (BP p.l.c.) was responsible for 28%, of consolidated operating revenues. The ten largest customers of Environmental Services accounted for approximately 89% of Environmental Services’ operating revenues. The loss of a single large client or a group of mid-size customers could have a material adverse effect on Environmental Services’ results of operations.

17

Competitive Conditions

The principal competitive factors in the environmental service business are price, customer service, reputation, experience, qualifications, availability of personnel and operating capabilities. In the United States, qualifications include USCG classification as an Oil Spill Removal Organization (“OSRO”). Environmental Services’ NRC is a USCG classified OSRO and it faces competition primarily from the Marine Spill Response Corporation, a non-profit OSRO funded by the major integrated oil companies. NRC also faces competition from other non-profit industry cooperatives and from those commercial contractors who target specific market niches in response, consulting and remediation. Internationally, competition for both oil spill response and emergency preparedness and management comes from a few private companies and regional oil industry cooperatives. Consulting and training service competitors range from small independent privately owned businesses to large engineering consulting groups and major defense contractors.

Risks of Foreign Operations

Environmental Services operates worldwide. For the years ended December 31, 2010, 2009 and 2008, 3%, 14% and 20%, respectively, of Environmental Services’ operating revenues were derived from its foreign operations.

Foreign operations are subject to inherent risks, including, among others, political instability, asset seizures, blockades, blacklisting, nationalization of assets, terrorist attacks, piracy, kidnapping, fluctuating currency values, hard currency shortages, controls on currency exchange, the repatriation of income or capital, import-export quotas and other forms of public and governmental regulation, all of which are beyond the control of Environmental Services. It is difficult to predict whether or when any of these conditions or events may develop in the future. The occurrence of any one or more of these conditions or events could have a material adverse effect on Environmental Services’ financial condition and its results of operations.

Commodity Trading and Logistics

Business

Commodity Trading and Logistics operates an integrated business involved in the purchase, storage, transportation and sale of agricultural and energy commodities. The principal commodities currently involved are sugar, ethanol, clean blendstocks and crude oil. Commodity Trading and Logistics contributed 28%, 28% and 13% of consolidated operating revenues in 2010, 2009 and 2008, respectively.

Products and Services

Energy. The energy group is primarily focused on the domestic merchandising (often referred to as “trading”) and transportation of physical ethanol, clean blendstocks, heavy naphtha and crude oil. The energy group also operates, through an investment in a joint venture, a food and fuel grade processing plant which produces beverage and industrial alcohol and fuel-grade ethanol. The output of the plant is sold primarily to the energy group and its joint venture partner.

Agricultural. The agricultural group is primarily focused on the global origination, trading and merchandising of sugar. The group’s involvement in sugar pairs producers and buyers and arranges for the transportation and logistics of the product.

Commodity Trading and Logistics uses a variety of transportation modes to transport its products, including trucks, railcars, river barges, pipelines and ocean going vessels, which are generally leased. The transportation services are typically provided by truck lines, railroads, pipelines and barge and ocean freight companies. Commodity Trading and Logistics leverages the asset base of SEACOR’s other business units, primarily Inland River Services, including its tank farm and handling facility in Sauget, IL, for the transportation and storage of product.

18

Markets

Commodity Trading and Logistics activities are global and dependent upon factors that Commodity Trading and Logistics cannot control, including macro and micro economic supply and demand factors, governmental intervention or mandates, weather patterns, and the price and availability of substitute products. With respect to sugar, the primary markets in which Commodity Trading and Logistics operate are countries that are net importers of sugar and include countries in South America and the Caribbean. Commodity Trading and Logistics produces, purchases, markets and sells ethanol to customers for blending into the U.S. gasoline pool and transports clean blendstocks for export.

The availability of agricultural commodities is affected by weather, plant diseases, governmental policies and agricultural growing patterns. Sugar demand is affected by worldwide consumption of food products, soft drinks and sweetened beverages, and by population growth, changes in per capita income and the relative prices of substitute sweeteners.

Ethanol demand is subject to overall gasoline demand and gasoline blending economics, governmental policies and mandates, the cost of the production of feedstock commodities such as corn and sugar, gasoline and oil prices, freight and handling costs. The demand for the clean blendstocks depends primarily on oil and natural gas liquids prices.

Customers and Contractual Arrangements

The principal purchasers of Commodity Trading and Logistics’ sugar are private importers and distributors. Commodity Trading and Logistics sells ethanol and blendstocks primarily to end users (gasoline blenders and their suppliers) and other market participants and may also purchase, sell, or exchange product with other market participants to optimize logistics or hedge market exposure.

In 2010, no single customer was responsible for 10% or more of consolidated operating revenues. The ten largest customers of Commodity Trading and Logistics accounted for approximately 76% of Commodity Trading and Logistics operating revenues. The loss of one or a few of these customers could have a material adverse effect on Commodity Trading and Logistics results of operations.

Competitive Conditions

The commodity trading and logistics business is highly competitive. Major competitors for the agricultural group include large agribusiness, major and independent trading houses and regional or local grower cooperatives. Major competitors for the energy group include other marketers, traders and other product suppliers.

Risk of Foreign Operations

For the year ended December 31, 2010, 2009 and 2008, 21%, 38% and 59%, respectively, of Commodity Trading and Logistics operating revenues were derived from foreign operations.

Foreign operations are subject to inherent risks, including, among others, political instability, asset seizures, blockades, blacklisting, nationalization of assets, terrorist attacks, piracy, kidnapping, fluctuating currency values, hard currency shortages, controls on currency exchange, the repatriation of income or capital, import-export quotas and other forms of public and governmental regulation, all of which are beyond the control of Commodity Trading and Logistics. It is difficult to predict whether or when any of these conditions or events may develop in the future. The occurrence of any one or more of these conditions or events could have a material adverse effect on Commodity Trading and Logistics’ financial condition and its results of operations.

Other

Harbor and Offshore Towing Services. As of December 31, 2010, Harbor and Offshore Towing Services operated a total of five ocean liquid tank barges and 30 vessels, of which 15 were conventional tugs, eight were Azimuth Stern Drive tugs, three were Forward Azimuth Drive tugs and four were Ship Docking Modules (“SDM™”). SDMs™ are innovative vessels designed and patented by the Company that are maneuverable, efficient and flexible and require fewer crew members than conventional harbor tugs. In 2010, no single customer was responsible for 10% or more of consolidated operating revenues. The ten largest customers of Harbor and Offshore Towing Services accounted for approximately 54% of Harbor and Offshore Towing Services’ operating revenues. The loss of one or a few of these customers could have a material adverse effect on Harbor and Offshore Towing Services results of operations.

As of December 31, 2010, Harbor and Offshore Towing Services’ fleet consisted of 30 tugs and five ocean liquid tank barges. The tugs were operating in various ports including four in Port Everglades, FL, four in the Port of Tampa, FL, one in Port Canaveral, FL, seven in Port Arthur, TX, four in Port Mobile, AL, four in Lake Charles, LA and one was engaged in offshore towing operations. In addition, five tugs and five ocean liquid tank barges were operating in St. Eustatius.

Other Joint Ventures, Leasing and Other Activities. The Company has noncontrolled equity investments in various entities including a company that designs and manufactures water treatment systems for sale or lease and three industrial aviation service businesses in Asia. The Company also engages in lending and leasing activities.

Government Regulation

Regulatory Matters

The Company’s operations are subject to significant United States federal, state and local regulations, as well as international conventions and the laws of foreign jurisdictions where the Company operates its equipment or where the equipment is registered. The Company’s domestically registered vessels are subject to the jurisdiction of the USCG, the National Transportation Safety Board (“NTSB”), the U.S. Customs Service and the U.S. Maritime Administration, as well as to the rules of private industry organizations such as the American Bureau of Shipping. These agencies and organizations establish safety standards and are authorized to investigate vessels and accidents and to recommend improved maritime safety standards. Aviation Services is subject to regulations pursuant to the Federal Aviation Act of 1958, as amended (“Federal Aviation Act”), and other statutes pursuant to Federal Aviation Regulations Part 135 Air Taxi Certificate granted by the FAA. The FAA regulates flight operations and, in this respect, has jurisdiction over Aviation Services personnel, aircraft, ground facilities and certain technical aspects of its operations. In addition to the FAA, the NTSB is authorized to investigate aircraft accidents and to recommend improved safety standards. The Company is also subject to the Communications Act of 1934, as amended, because of the use of radio facilities in Aviation Services operations.

Offshore Marine Services, Marine Transportation Services and Inland River Services are subject to the Shipping Act, 1916, as amended (“1916 Act”), and the Merchant Marine Act of 1920, as amended (“1920 Act,” or “Jones Act” and, together with the 1916 Act, “Shipping Acts”), which govern, among other things, the ownership and operation of vessels used to carry cargo between U.S. ports known as “U.S. coastwise trade.” The Shipping Acts require that vessels engaged in U.S. coastwise trade be owned by U.S. citizens and built in the United States. For a corporation engaged in the U.S. coastwise trade to be deemed a U.S. citizen: (i) the corporation 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 corporation must be owned by U.S. “citizens” (as defined in the Shipping Acts). Should the Company fail to comply with the U.S. citizenship requirements of the Shipping Acts, it would be prohibited from operating its vessels in the U.S. coastwise trade during the period of such non-compliance.

20

To facilitate compliance with the Shipping Acts, SEACOR’s Restated Certificate of Incorporation: (i) limits the aggregate percentage ownership by non-U.S. citizens of any class of SEACOR’s capital stock (including Common Stock) to 22.5% of the outstanding shares of each such class to ensure that such foreign ownership will not exceed the maximum percentage permitted by applicable maritime law (presently 25%) but authorizes SEACOR’s Board of Directors, under certain circumstances, to increase the foregoing percentage to 24%, (ii) requires institution of a dual stock certification system to help determine such ownership and (iii) permits the Board of Directors to make such determinations as reasonably may be necessary to ascertain such ownership and implement such limitations. In addition, SEACOR’s by-laws provide that the number of non-U.S. citizen directors shall not exceed a minority of the number necessary to constitute a quorum for the transaction of business and restrict any non-U.S. citizen officer from acting in the absence or disability of the Chairman of the Board of Directors, the Chief Executive Officer or the President.

Aviation Services’ helicopters operating in the United States are subject to registration and citizenship requirements under the Federal Aviation Act. This Act requires that before an aircraft may be legally operated in the United States, it must be owned by “citizens of the United States,” which, in the case of a corporation, means a corporation: (i) organized under the laws of the United States or of a state, territory or possession thereof, (ii) of which at least 75% of its voting interests are owned or controlled by persons who are U.S. “citizens” (as defined in the Federal Aviation Act and regulations promulgated thereunder), and (iii) of which the president and at least two-thirds of the board of directors and managing officers are U.S. citizens.

Marine Transportation Services, Inland River Services, Harbor and Offshore Towing Services and Offshore Marine Services operate vessels that are registered in the United States. Offshore Marine Services, Harbor and Offshore Towing Services, and an Inland River Services joint venture operate vessels registered in a number of foreign jurisdictions. Vessels registered in these jurisdictions are subject to the laws of the applicable jurisdiction as to ownership, registration, manning and safety. In addition, the vessels are subject to the requirements of a number of international conventions that are applicable to vessels depending on their jurisdiction of registration. Among the more significant of these conventions are: (i) the 1978 Protocol Relating to the International Convention for the Prevention of Pollution from Ships, (ii) the International Convention on the Safety of Life at Sea, 1974 and 1978 Protocols, and (iii) the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers, 1978. The Company believes that its vessels registered in foreign jurisdictions are in compliance with all applicable material regulations and have all licenses necessary to conduct their business. In addition, vessels operated as standby safety vessels in the North Sea are subject to the requirements of the Department of Transport of the United Kingdom pursuant to the United Kingdom Safety Act.

All of Marine Transportation Services’, Harbor and Offshore Towing Services’, certain of Offshore Marine Services’ vessels and all of Inland River Services’ liquid tank barges are subject to periodic inspection and survey by, and drydocking and maintenance requirements of, the USCG and/or the American Bureau of Shipping and other marine classification societies. Moreover, to ensure compliance with applicable safety regulations, the USCG is authorized to inspect vessels at will.

NRC is classified by the USCG as an OSRO for every port in the continental United States, Hawaii and the Caribbean. The OSRO classification process is strictly voluntary. Vessel owners and other customers subject to OPA 90 who utilize classified OSROs are exempt from the requirement to list their response resources in their plans. The classification process permits the USCG and these customers to evaluate the ability of an OSRO to respond to and recover oil spills of various types and sizes in different operating environments and geographic locations.

In addition to the USCG, the EPA, the Office of Pipeline Safety, the Bureau of Ocean Energy (“BOE”) and certain individual states regulate vessels, facilities and pipelines in accordance with the requirements of OPA 90 or under analogous state law. There is currently little uniformity among the regulations issued by these agencies.

21

When responding to third-party oil spills, Environmental Services enjoys immunity from liability under federal law and some state laws for any spills arising from its response efforts, except in the event of death or personal injury as a result of its gross negligence or willful misconduct.

Environmental Compliance

As more fully described below, all of the Company’s businesses are, to some degree, subject to federal, state, local and international laws and regulations relating to environmental protection and occupational safety and health, including laws that govern the discharge of oil and pollutants into navigable waters. Violations of these laws may result in civil and criminal penalties, fines, injunctions or other sanctions.

The Company believes that its operations are currently in compliance with all material environmental laws and regulations. It does not expect that it will be required to make capital expenditures in the near future that are material to its financial position or operations to comply with environmental laws and regulations; however, because such laws and regulations are frequently changing and may impose increasingly strict requirements, the Company cannot predict the ultimate cost of complying with these laws and regulations. The recent trend in environmental legislation and regulation is generally toward stricter standards, and it is the Company’s view that this trend is likely to continue.

OPA 90 establishes a regulatory and liability regime for the protection of the environment from oil spills. OPA 90 applies to owners and operators of facilities operating near navigable waters and owners and operators of vessels operating in U.S. waters, which include the navigable waters of the United States and the 200-mile Exclusive Economic Zone of the United States. Although it appears to apply in general to all vessels, for purposes of its liability limits and financial responsibility and response planning requirements, OPA 90 differentiates between tank vessels (which include the Company’s chemical and petroleum product vessels and liquid tank barges) and “other vessels” (which include the Company’s tugs, offshore support vessels and dry cargo barges).

Under OPA 90, owners and operators of regulated facilities and owners and operators or certain charterers of vessels are “responsible parties” and are jointly, severally and strictly liable for removal costs and damages arising from facility and vessel oil spills unless the spill results solely from the act or omission of certain third parties under specified circumstances, an act of God or an act of war. Damages are defined broadly to include: (i) injury to natural resources and the costs of remediation thereof; (ii) injury to, or economic losses resulting from the destruction of, real and personal property; (iii) net loss by the United States government, a state or political subdivision thereof, of taxes, royalties, rents, fees and profits; (iv) lost profits or impairment of earning capacity due to property or natural resources damage; (v) net costs of providing increased or additional public services necessitated by a spill response, such as protection from fire, safety or other hazards; and (vi) loss of subsistence use of available natural resources.

The statutory liability of responsible parties for tank vessels is limited to the greater of $1,200 per gross ton or $10 million ($2 million for a vessel of 3,000 gross tons or less) per vessel; for any “other vessel,” such liability is limited to the greater of $600 per gross ton or $500,000 per vessel. These liability limits do not apply (a) if an incident is caused by the responsible party’s violation of federal safety, construction or operating regulations or by the responsible party’s gross negligence or willful misconduct, (b) if the responsible party fails to report the incident or to provide reasonable cooperation and assistance in connection with oil removal activities as required by a responsible official or (c) if the responsible party fails to comply with certain governmental orders.

Under OPA 90, with certain limited exceptions, all newly-built oil tankers carrying crude oil and petroleum products in U.S. waters must have double-hulls. Existing single-hull, double-side or double-bottom tank vessels, unless retrofitted with double-hulls, must be phased out of service by January 1, 2015, depending upon the vessel’s size, age and place of discharge.

22

OPA 90 expanded pre-existing financial responsibility requirements and requires tank vessel owners and operators to establish and maintain with the USCG evidence of insurance or qualification as a self-insurer or other evidence of financial responsibility sufficient to meet their potential liabilities under OPA 90. The Company has satisfied USCG regulations by providing evidence of financial responsibility demonstrated by commercial insurance and self-insurance. The regulations also implement the financial responsibility requirements of the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), described below, which imposes liability for discharges of hazardous substances such as chemicals, in an amount equal to $300 per gross ton, thus increasing the overall financial responsibility in the case of tank vessels from $1,200 to $1,500 per gross ton.

OPA 90 amended the Clean Water Act (“CWA”), described below, to require the owner or operator of certain facilities or of a tank vessel to prepare facility or vessel response plans and to contract with oil spill removal organizations to remove, to the maximum extent practicable, a worst-case discharge. The Company has complied with these requirements. The Company expects its pollution liability insurance to cover any cost of spill removal subject to overall coverage limitations of $1.0 billion; however, a failure or refusal of the insurance carrier to provide coverage in the event of a catastrophic spill could result in material liability in excess of available insurance coverage, resulting in a material adverse effect on the Company’s business, financial position or its results of operations.

OPA 90 allows states to impose their own liability regimes with respect to oil pollution incidents occurring within their boundaries and many states have enacted legislation providing for unlimited liability for oil spills. Some states have issued regulations addressing financial responsibility and vessel and facility response planning requirements. The Company does not anticipate that state legislation or regulations will have any material impact on its operations.

In addition to OPA 90, the following are examples of environmental laws that relate to the Company’s business and operations:

The federal CWA and comparable state and local laws impose restrictions on the discharge of pollutants into the navigable waters of the United States. These laws also provide for civil and criminal penalties, as well as injunctive relief, for violations. A related statute, the Coastal Zone Management Act, authorizes state development and implementation of programs to manage non-point source pollution to restore and protect coastal waters.

The federal Resource Conservation and Recovery Act and comparable state and local laws regulate the generation, transportation, treatment, storage and disposal of hazardous and certain non-hazardous wastes. These laws also provide for civil and criminal penalties, as well as injunctive relief, for violations. The Company’s operations may generate or, in some cases, result in the transportation of these regulated wastes.

CERCLA and comparable state laws establish strict and, under certain circumstances, joint and several liabilities for specified parties in connection with liability for the investigation and remediation of releases of hazardous materials into the environment and damages to natural resources.

The federal Clean Air Act and comparable state and local laws impose restrictions on the emission of air pollutants into the atmosphere. These laws also provide for civil and criminal penalties, as well as injunctive relief, for violations. The Company’s chemical and petroleum product carrier vessels are subject to vapor control and recovery requirements when loading, unloading, ballasting, cleaning and conducting other operations in certain ports and are equipped with vapor control systems that satisfy these requirements in all material respects.

The Company manages exposure to losses from the above-described laws through its efforts to use only well-maintained, well-managed and well-equipped facilities and vessels and its development of safety and environmental programs, including a maritime compliance program and its insurance program. The Company

23

believes it will be able to accommodate reasonably foreseeable environmental regulatory changes. There can be no assurance, however, that any future regulations or requirements or that any discharge or emission of pollutants by the Company will not have a material adverse effect on the Company’s business, financial position or its results of operations.

Security

Heightened awareness of security needs brought about by the events of September 11, 2001 has caused the USCG, the IMO, states and local ports to adopt heightened security procedures relating to ports and vessels. The Company has updated its procedures in light of the new requirements.

In 2002, Congress passed the Maritime Transportation Security Act (“MTSA”), which together with the IMO’s recent security proposals (collectively known as the International Ship and Port Facility Security Code or “ISPS”), requires specific security plans for the Company’s vessels and rigorous crew identification requirements. The following vessels are subject to the requirements of the ISPS:

• U.S.-flag vessels operating in the Jones Act trade that are at least 100 gross registered tons

• U.S.-flag vessels operating on an international voyage

• Foreign flag vessels that are at least 500 gross tons under the International Tonnage Convention

The Company has implemented security plans and procedures for each of its U.S.-flag vessels and its terminal operation in Sauget, Illinois pursuant to rules implementing the MTSA that have been issued by the USCG. The Company’s U.S.-flag vessels subject to the requirements of ISPS, all foreign flag vessels, and U.S.-flag vessels operating on international voyages were in compliance with ISPS requirements effective July 1, 2004.

Industry Hazards and Insurance

Vessel operations involve inherent risks associated with carrying large volumes of cargo and rendering services in a marine environment. In addition, helicopter operations are potentially hazardous and may result in incidents or accidents. Hazards include adverse weather conditions, collisions, fire and mechanical failures, which may result in death or injury to personnel, damage to equipment, loss of operating revenues, contamination of cargo, pollution and other environmental damages and increased costs. The Company maintains marine and aviation hull, liability and war risk, general liability, workers compensation and other insurance customary in the industries in which the Company operates. The Company also conducts training and safety programs to promote a safe working environment and minimize hazards.

Employees

As of December 31, 2010, the Company employed 5,311 individuals directly and indirectly through crewing or manning agreements. Substantially all indirect employees support Offshore Marine Services vessel operations.

As of December 31, 2010, Offshore Marine Services employed 734 seafarers in the North Sea, some of whom were members of a union under the terms of an ongoing agreement. In the United States, a total of 256 employees in Marine Transportation Services and Harbor and Offshore Towing Services are unionized under agreements that expire at varying times through December 31, 2012. Certain individuals in Environmental Services are also represented by unions.

Management considers relations with its employees to be satisfactory.

ITEM 1A. RISK FACTORS

Risks, Uncertainties and Other Factors That May Affect Future Results

The Company’s results of operations, financial condition and cash flow may be adversely affected by numerous risks. Carefully consider the risks described below, which represent some of the more critical risk factors that affect the Company, as well as the other information that has been provided in this Annual Report on Form 10-K. The risks described below include all known material risks faced by the Company. Additional risks not presently known may also impair the Company’s business operations.

Difficult economic conditions could materially adversely affect the Company. The success of the Company’s business is both directly and indirectly dependent upon conditions in the global financial markets and economic conditions throughout the world that are outside its control and difficult to predict. Uncertainty about global economic conditions may lead businesses to postpone spending in response to tighter credit and reductions in income or asset values, which may lead many lenders and institutional investors to reduce, and in some cases, cease to provide funding to borrowers. These factors may also adversely affect the Company’s liquidity and financial condition (including the failure of lenders participating in the Company’s credit facility to fulfill their commitments and obligations), and the liquidity and financial condition of the Company’s customers. Tight credit conditions could limit the Company’s ability to secure additional financing, if required, due to difficulties accessing the capital markets. 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 impact on the Company’s business and investments, which could reduce its revenues and profitability. Although the Company has some ongoing exposure to credit risks on its accounts receivable balances, these risks are heightened during periods when economic conditions worsen. The Company has procedures that are designed to monitor and limit exposure to credit risk on its receivables; however, there can be no assurance that such procedures will effectively limit its credit risk and avoid losses that could have a material adverse effect on the Company’s financial position and its results of operations. Unstable economic conditions may increase the volatility of the Company’s stock price.

There are risks associated with the Company’s debt structure. The Company’s ability to meet its debt service obligations is dependent upon its future operating results, which are subject to general economic conditions, industry cycles and financial, business and other factors, many of which are beyond its control. The Company’s debt levels and the terms of its indebtedness may limit its liquidity and flexibility in obtaining additional financing and pursuing other business opportunities. In addition, the Company’s overall debt level and/or market conditions could lead the credit rating agencies to lower the Company’s corporate credit ratings, which could limit its ability to issue additional debt in amounts and/or terms that it considers reasonable.

Demand for many of the Company’s services is impacted by the level of activity in the offshore oil and natural gas exploration, development and production industry. The level of offshore oil and natural gas exploration, development and production activity has historically been volatile and that volatility is likely to continue. The level of activity is subject to large fluctuations in response to relatively minor changes in a variety of factors that are beyond the Company’s control, including:

• prevailing oil and natural gas prices and expectations about future prices and price volatility

• the cost of exploring for, producing and delivering oil and natural gas offshore

• worldwide demand for energy, other petroleum products and chemical products

• availability and rate of discovery of new oil and natural gas reserves in offshore areas

• local and international political and economic conditions, and policies including cabotage and local content laws

• technological advances affecting energy production and consumption

• weather conditions

25

• environmental regulation

• the ability of oil and natural gas companies to generate or otherwise obtain funds for capital projects

A prolonged material downturn in oil and natural gas prices is likely to cause a substantial decline in expenditures for exploration, development and production activity, which would result in a decline in demand and lower rates for the Company’s offshore energy support services and tanker services. Moreover, for the year ended December 31, 2010, approximately 46% of Offshore Marine Services’ and 48% of Aviation Services’ operating revenues were earned in the U.S. Gulf of Mexico and are therefore dependent on levels of activity in that region, which may differ from levels of activity in other regions of the world.

Adverse results of legal proceedings could materially adversely affect the Company. The Company is subject to and may in the future be subject to a variety of legal proceedings and claims that arise out of the ordinary conduct of its business. Results of legal proceedings cannot be predicted with certainty. Irrespective of its merits, litigation may be both lengthy and disruptive to the Company’s operations and may cause significant expenditure and diversion of management attention. The Company may be faced with significant monetary damages or injunctive relief against it that could materially adversely affect a portion of its business operations or materially and adversely affect the Company’s financial position and its results of operations should the Company fail to prevail in certain matters.

The Company may undertake one or more significant corporate transactions that may not achieve their intended results, may adversely affect the Company’s financial condition and its results of operations, and may result in additional risks to its businesses. The Company continuously evaluates the acquisition of operating businesses and assets and may in the future undertake significant transactions. Any such transaction could be material to the Company’s business and could take any number of forms, including mergers, joint ventures, investments in new lines of business and the purchase of equity interests or assets. The form of consideration for such transactions may include, among other things, cash, common stock or equity interests in the Company’s subsidiaries. The Company also evaluates the disposition of its operating businesses and assets, in whole or in part, which could take the form of asset sales, mergers or sales of equity interests in its subsidiaries (privately or through a public offering), or the spin-off of equity interests of the Company’s subsidiaries to its stockholders.

These types of significant transactions may present significant risks and uncertainties, including distraction of management from current operations, insufficient revenue to offset liabilities assumed, potential loss of significant revenue and income streams, unexpected expenses, inadequate return of capital, potential acceleration of taxes currently deferred, regulatory or compliance issues, the triggering of certain covenants in the Company’s debt instruments (including accelerated repayment) and other unidentified issues not discovered in due diligence. As a result of the risks inherent in such transactions, the Company cannot guaranty that any such transaction will ultimately result in the realization of the anticipated benefits of the transaction or that significant transactions will not have a material adverse impact on the Company’s financial condition or its results of operations. If the Company were to complete such an acquisition, disposition, investment or other strategic transaction, it may require additional debt or equity financing that could result in a significant increase in its amount of debt or the number of outstanding shares of its Common Stock.

Investment in new business strategies and initiatives present risks not originally contemplated. The Company has invested, and in the future may again invest, in new business plans or acquisitions, some of which may not be directly linked to existing business lines or activities. These activities may involve significant risks and uncertainties, including distraction of management from current operations, insufficient revenue to offset liabilities assumed and expenses associated with the plans or acquisitions, inadequate return of capital, and unidentified issues not discovered in due diligence. Investments in these positions also may involve securities that are not very liquid. As a result of the risks inherent in new ventures, there can be no assurance that any such venture will be successful, or that new ventures will not have a material adverse impact on the Company’s financial position and its results of operations.

The Company engages in hedging activities which exposes it to risks. The Company for corporate purposes and also as part of its energy trading activities, may use futures and swaps to hedge risks, such as

26

escalation in fuel costs, agricultural raw materials, movements in foreign exchange rates and interest rates. The Company also may purchase larger than usual inventory to lock in costs when it believes there may be large increases in the price of raw materials or other material used in its businesses. Such purchases expose the Company to risks of meeting margin calls and drawing on its capital, counterparty risks due to failure of an exchange or institution with which it has done a swap, incurring higher costs than competitors or similar businesses that do not engage in such strategies, and losses on its investment portfolio. Such strategies can also cause earnings to be volatile.

The Company’s operations in the Gulf of Mexico may be adversely impacted by the Deepwater Horizon drilling rig accident and resulting oil spill. On April 22, 2010, the Deepwater Horizon, a semi-submersible deepwater drilling rig operating in the U.S. Gulf of Mexico, sank after an apparent blowout and fire resulting in a significant flow of hydrocarbons from the BP Macondo well (the “Deepwater Horizon/BP Macondo Well Incident”). The Company’s Offshore Marine Services and Aviation Services segments have extensive operations in the U.S. Gulf of Mexico, which, along with those of certain of its customers, may be adversely impacted by, among other factors:

• the recently lifted drilling moratorium by the U.S. Department of the Interior that directed lessees and operators to cease drilling all new deepwater wells on federal leases in the U.S. Gulf of Mexico, the additional safety and certification requirements for drilling activities imposed for the approval of development and production activities and the delayed approval of applications to drill in both deep and shallow-water areas;

• the suspension, stoppage or termination by customers of existing contracts and the demand by customers for new or renewed contracts in the U.S. Gulf of Mexico and other affected regions;

• unplanned customer suspensions, cancellations, rate reductions or non-renewals of commitments to charter vessels and aviation equipment or failures to finalize commitments to charter vessels and aviation equipment;

• new or additional government regulations or laws concerning drilling operations in the U.S. Gulf of Mexico and other regions; and

• the cost or availability of relevant insurance coverage.

Any one or a combination of these factors could reduce revenues, increase operating costs and have a material adverse effect on the Company’s financial position and its results of operations.

The Company could incur liability in connection with providing spill response services. The Company may incur increased legal fees and costs in connection with providing spill and emergency response services, including the Company’s involvement in response to the Deepwater Horizon/BP Macondo Well Incident. Several of the Company’s business segments are currently defendants in litigation arising from the Deepwater Horizon/BP Macondo Well Incident and the Company expects it may be named in additional litigation regarding its response services. Although companies are generally exempt in the United States from liability under the CWA for their own actions and omissions in providing spill response services, this exemption might not apply if a company were found to have been grossly negligent or to have engaged in willful misconduct, or if it were to have failed to provide these services consistent with applicable regulations and directives under the CWA. In addition, the exemption under the federal CWA would not protect a company against liability for personal injury or wrongful death claims, or against prosecution under other federal or state laws. Although most of the states within the United States in which the Company provides services have adopted similar exemptions, several states have not. If a court or other applicable authority were to determine that the Company does not benefit from federal or state exemptions from liability in providing emergency response services, or if the other defenses asserted by the Company and its business segments are rejected, the Company could be liable together with the local contractor and the responsible party for any resulting damages, including damages caused by others, subject to the indemnification provisions and other liability terms and conditions negotiated with its domestic clients. In the international market, the Company does not benefit from the spill response liability protection provided by

27

the CWA and, therefore, is subject to the liability terms and conditions negotiated with its international clients, in addition to any other defenses available to the Company and its business segments. In connection with claims relating to clean-up operations following the Deepwater Horizon/BP Macondo Well Incident, the responsible party had acknowledged and agreed to indemnify and defend one of the Company’s business segments pursuant to certain contractual agreements. The Company continues to seek indemnification for other business segments for claims relating to clean-up operations following the Deepwater Horizon/BP Macondo Well Incident pursuant to similar contractual arrangements.

If Congress repeals the $75.0 million cap for non-reclamation liabilities under OPA 90, there may be increased exposure for remediation work and the cost for securing insurance for such work may become prohibitively expensive. Without affordable insurance and appropriate legislative regulation limiting liability, drilling, exploration and further investment in oil and gas exploration in the U.S. Gulf of Mexico may be discouraged and thus reduce the demand for the Company’s services.

Negative publicity may adversely impact the Company. Media coverage and public statements that insinuate improper actions by the Company, regardless of their factual accuracy or truthfulness, may result in negative publicity, litigation or governmental investigations by regulators. Addressing negative publicity and any resulting litigation or investigations may distract management, increase costs and divert resources. Negative publicity may have an adverse impact on the Company’s reputation and the morale of its employees, which could adversely affect the Company’s financial position and its results of operations.

Increased domestic and international laws and regulations may adversely impact the Company. Changes in laws or regulations regarding offshore oil and gas exploration and development activities, including the recently lifted drilling moratorium issued by the U.S. Department of the Interior directing lessees and operators to cease drilling all new deepwater wells on federal leases in the U.S. Gulf of Mexico, may increase the cost or availability of insurance coverage and may influence decisions by customers or other industry participants that could reduce demand for the Company’s services, which would have a negative impact on the Company’s Offshore Marine Services and Aviation Services segments.

Risks from the Company’s international operations. The Company operates vessels, leases helicopters, provides environmental services and transacts other business worldwide. Its ability to compete in the international offshore energy support market and environmental services market may be adversely affected by foreign government regulations that favor or require the awarding of contracts to local competitors, or that require foreign persons to employ citizens of, or purchase supplies from, a particular jurisdiction. Further, the Company’s foreign subsidiaries may face governmentally imposed restrictions on their ability to transfer funds to their parent company.

Activity outside the United States involves additional risks, including the possibility of:

• United States embargoes, restrictive actions by foreign governments, including asset seizure

• foreign taxation and changes in foreign tax laws

• limitations on the repatriation of earnings

• local cabotage and local ownership laws and requirements

• nationalization and expropriation

• loss of contract rights

• political instability, war and civil disturbances or other risks that may limit or disrupt markets

• changes in currency exchange rates

Unstable political, military and economic conditions in foreign countries where a significant proportion of Offshore Marine Services’ operations are conducted could adversely impact the Company’s business. During the year ended December 31, 2010, approximately 53% of Offshore Marine Services’ operating revenues

28

resulted from its foreign operations. These operations are subject to risks, including potential vessel seizure, terrorist attacks, piracy, kidnapping, and nationalization of assets, currency restrictions, import or export quotas and other forms of public and government regulation, all of which are beyond the Company’s control. Economic sanctions or an oil embargo, for example, could have significant impact on activity in the oil and gas industry and, correspondingly, on the Company should Offshore Marine Services operate vessels in a country subject to any sanctions or embargo, or in the surrounding region to the extent any sanctions or embargo disrupt its operations.

Offshore Marine Services, Marine Transportation Services and Aviation Services rely on several customers for a significant share of their revenues, the loss of any of which could adversely affect each of their businesses and operating results. Offshore Marine Services’, Marine Transportation Services’ and Aviation Services’ customers are primarily major oil companies and large independent oil and gas exploration and production companies. The portion of Offshore Marine Services’, Marine Transportation Services’ or Aviation Services’ revenues attributable to any single customer may change over time, depending on the level of relevant activity by any such customer, the segments ability to meet the customer’s needs and other factors, many of which are beyond the Company’s control. The loss of any large customer or several mid-size customers could have a material and adverse effect on such segment’s or the Company’s financial position or its results of operations.

Consolidation of the Company’s customer base could adversely affect demand for its services and reduce its revenues. In recent years, oil and natural gas companies, energy companies and drilling contractors have undergone substantial consolidation and additional consolidation is possible. Consolidation results in fewer companies to charter or contract for the Company’s services. Also, merger activity among both major and independent oil and natural gas companies affects exploration, development and production activity as the consolidated companies integrate operations to increase efficiency and reduce costs. Less promising exploration and development projects of a combined company may be dropped or delayed. Such activity may result in an exploration and development budget for a combined company that is lower than the total budget of both companies before consolidation, which could adversely affect demand for the Company’s Offshore Marine Services’ vessels, Marine Transportation Services’ tankers, Aviation Services’ helicopters and Environmental Services’ products and services, thereby reducing the Company’s revenues.

The Company may be unable to maintain or replace its offshore support vessels as they age. As of December 31, 2010, the average age of the Company’s Offshore Marine Services vessels, excluding its standby safety vessels, was approximately 11.5 years. The Company believes that after an offshore support vessel has been in service for approximately 20 years, the expense (which typically increases with age) necessary to satisfy required marine certification standards may not be economically justifiable. The Company may be unable to carry out drydockings of its vessels or may be limited by insufficient shipyard capacity, which could adversely affect its ability to maintain its vessels. In addition, market conditions may not justify these expenditures or enable the Company to operate its older vessels profitably during the remainder of their economic lives. There can be no assurance that the Company will be able to maintain its fleet by extending the economic life of existing vessels, or that its financial resources will be sufficient to enable it to make expenditures necessary for these purposes or to acquire or build replacement vessels.

An increase in the supply of offshore support vessels or tankers could have an adverse impact on the charter rates earned by the Company’s offshore support vessels and tankers. Expansion of the supply of the

worldwide offshore support vessel fleet would increase competition in the markets which Offshore Marine Services’ operates. The refurbishment of disused or “mothballed” vessels, conversion of vessels from uses other than oil and gas exploration and production support and related activities or construction of new vessels could all add vessel capacity to current worldwide levels. A significant increase in vessel capacity could lower charter rates and result in lower operating revenues. Similarly, should competitors in the domestic petroleum and chemical product tanker industry construct a significant number of new tankers or large capacity integrated or articulated tug and barge units, demand for tanker assets could be adversely affected.

If the Company does not restrict the amount of foreign ownership of its Common Stock, it could be prohibited from operating offshore support vessels, inland river vessels and barges and tankers in parts of the

29

United States and could be prohibited from operating helicopters, which would adversely impact its business and operating results. The Company is subject to the Shipping Acts, which govern, among other things, the ownership and operation of offshore support vessels, tankers and barges used to carry cargo between U.S. ports. The Shipping Acts require that vessels engaged in the “U.S. coastwise trade” be owned by U.S. citizens and built in the United States. The Company is also subject to regulations pursuant to the Federal Aviation Act and other statutes (“Aviation Acts”). Generally, aircraft operating in the United States must be registered in the United States. In order to register such aircraft under the Aviation Acts, the Company must be owned or controlled by U.S. citizens. Although the Company’s Certificate of Incorporation and by-laws contain provisions intended to assure compliance with these provisions of the Shipping Acts and the Aviation Acts, a failure to maintain compliance would adversely affect the Company’s financial position and its results of operations and the Company would be prohibited from operating vessels in the U.S. coastwise trade and helicopters in the United States during any period in which the Company did not comply with these regulations.

Repeal, Amendment, Suspension or Non-Enforcement of the Shipping Acts would result in additional competition for Offshore Marine Services, Marine Transportation Services and Inland River Services. A substantial portion of Offshore Marine Services’, Marine Transportation Services’ and Inland River Services’ operations are conducted in the U.S. coastwise trade. Under certain provisions of the Shipping Acts, this trade is restricted to vessels built in the United States, owned and manned by U.S. citizens and registered under United States law. There have been attempts to repeal or amend such provisions, and such attempts are expected to continue in the future. Repeal of such provisions would result in additional competition from vessels built in lower-cost foreign shipyards, owned and manned by foreign nationals with promotional foreign tax incentives and with lower wages and benefits than U.S. citizens, which could have a material adverse effect on the Company’s business, financial position and its results of operations.

The Outer Continental Shelf Lands Act, as amended, provides the federal government with broad discretion in regulating the leasing of offshore resources for the production of oil and gas. Because Offshore Marine Services’ and Aviation Services’ operations rely on offshore oil and gas exploration and production, the government’s exercise of authority under the provisions of the Outer Continental Shelf Lands Act to restrict the availability of offshore oil and gas leases could have a material adverse effect on the Company’s financial position and its results of operations.

Failure to maintain an acceptable safety record may have an adverse impact on the Company’s ability to retain customers. The Company’s customers consider safety and reliability a primary concern in selecting a service provider. The Company must maintain a record of safety and reliability that is acceptable to its customers. Should this not be achieved, the ability to retain current customers and attract new customers may be adversely affected.

Operational risks could disrupt operations and expose the Company to liability. The operation of offshore support vessels, tankers, inland river towboats, tugs, helicopters, oil spill response vessels and barges is subject to various risks, including catastrophic disaster, adverse weather, mechanical failure and collision. Additional risks relating to the operation of helicopters include harsh weather and marine conditions, mechanical failures, crashes, and collisions, which may result in personal injury, loss of life, damage to property and equipment, and the suspension or reduction of operations. The Company’s aircraft have been involved in accidents in the past, some of which have included loss of life and property damage. The Company may experience similar accidents in the future. Additional risks to vessels include adverse sea conditions, capsizing, grounding, oil and hazardous substance spills and navigation errors. These risks could endanger the safety of the Company’s personnel, equipment, cargo and other property, as well as the environment. If any of these events were to occur, the Company could be held liable for resulting damages, including loss of revenues from or termination of charter contracts, higher insurance rates, and damage to the Company’s reputation and customer relationships. In addition, the affected vessels or helicopters could be removed from service and would then not be available to generate revenues.

Revenues from Aviation Services are dependent on flight hours, which are subject to adverse weather conditions and seasonality. A significant portion of the Company’s revenues from Aviation Services is

30

dependent on actual flight hours. Prolonged periods of adverse weather, storms and the effect of fewer hours of daylight adversely impact Aviation Services. Winter months generally have more days of adverse weather conditions than the other months of the year, with poor visibility, high winds, and heavy precipitation and fewer daylight hours, all of which adversely affect helicopter operations. In addition, June through November is tropical storm season in the U.S. Gulf of Mexico; during tropical storms, helicopters are unable to operate in the area of a storm. In addition, many of Aviation Services’ facilities are located along the U.S. Gulf of Mexico coast, and tropical storms may cause damage to its property.

The helicopter industry is subject to intense competition. The helicopter industry is highly competitive and involves an aggressive bidding process among providers having the necessary equipment, operational experience and resources. The Company must provide safe and efficient service or risk losing customers or the termination of contracts, which could result in lost market share and have a material adverse effect on the Company’s financial position and its results of operations.

Consolidation in the aircraft parts industry could affect the service and operation of Aviation Services’ helicopters. A reduction in the number of approved parts suppliers or a consolidation in the spare parts redistribution market could interrupt or delay the supply of aircraft components, adversely affecting Aviation Services’ ability to meet service commitments to customers and could cause Aviation Services to lose opportunities with existing and future customers. Aviation Services might not be able to qualify or identify alternative suppliers in a timely fashion, or at all. Consolidations involving suppliers could further reduce the number of alternatives for Aviation Services and affect the cost of components. An increase in the cost of components could make Aviation Services less competitive and result in lower margins.

Revenues from Marine Transportation Services could be adversely affected by a decline in demand for domestic refined petroleum products, crude oil or chemical products, or a change in existing methods of delivery. A reduction in domestic consumption of refined petroleum products, crude oil or chemical products, the development of alternative methods of delivery of refined petroleum, crude oil, and a reduction in domestic refining capacity could reduce demand for the Company’s services.

Construction of additional refined petroleum product, natural gas or crude oil pipelines could have a material adverse effect on Marine Transportation Services’ revenues. Long-haul transportation of refined petroleum products, crude oil and natural gas is generally less costly by pipeline than by tanker. Existing pipeline systems are either insufficient to meet demand in, or do not reach all of, the markets served by Marine Transportation Services’ tankers. The construction and operation of new pipeline segments to the Florida market could have a material and adverse effect on Marine Transportation Services’ business.

The Company may have to phase-out its double-bottom tanker from petroleum product transportation service in U.S. waters. The Oil Pollution Act of 1990 establishes a phase-out schedule, depending upon vessel size and age, for non-double-hull vessels carrying crude oil and petroleum products in the U.S. coastwise trade. The phase-out date for the Company’s non-double-hull tanker, the Seabulk America, is 2015 and, unless this vessel is modified with a double-hull, which would require substantial capital expenditure, it will be prohibited from transporting crude oil and petroleum products in the U.S. coastwise trade after this date. It would also be prohibited from transporting petroleum products in most foreign and international markets under a phase-out schedule established by the International Maritime Organization.

The Company may lose eligibility for two tankers retrofitted to a double-hull configuration to engage in U.S. coastwise trade. Two of Marine Transportation Services’ tankers that operate in the U.S. coastwise trade, which is restricted to vessels built or rebuilt in the United States, were retrofitted to a double-hull configuration in a foreign shipyard. The Company is party to litigation regarding the eligibility of such tankers following the retrofit to engage in the U.S. coastwise trade, the loss of which could adversely affect the Company’s financial condition and its results of operations. See Item 3. “Legal Proceedings” for a complete description of this litigation.

31

The Company is subject to complex laws and regulations, including environmental laws and regulations that can adversely affect the cost, manner or feasibility of doing business. Increasingly stringent federal, state, local and international laws and regulations governing worker safety and health and the manning, construction and operation of vessels significantly affect the Company’s operations. Many aspects of the marine industry are subject to extensive governmental regulation by the U.S. Coast Guard (“USCG”), Occupational Safety and Health Administration (“OSHA”), the National Transportation Safety Board (“NTSB”) and the U.S. Customs Service, and to regulation by port states and class society organizations, such as the American Bureau of Shipping, as well as to international regulations from international treaties, such as the Safety of Life at Sea convention administered by port states and class societies. The USCG, OSHA and NTSB set safety standards and are authorized to investigate vessel accidents and recommend improved safety standards. The U.S. Customs Service and USCG are authorized to inspect vessels at will.

The Company’s business and operations are also subject to federal, state, local and international laws and regulations that control the discharge of oil and hazardous materials into the environment or otherwise relate to environmental protection and occupational safety and health. Compliance with such laws and regulations may require installation of costly equipment or operational changes, and the phase-out of certain product tankers. Failure to comply with applicable laws and regulations may result in administrative and civil penalties, criminal sanctions or the suspension or termination of the Company’s operations. Some environmental laws impose strict and, under certain circumstances, joint and several liability for remediation of spills and releases of oil and hazardous materials and damage to natural resources, which could subject the Company to liability without regard to whether it was negligent or at fault. These laws and regulations may expose the Company to liability for the conduct of or conditions caused by others, including charterers. Moreover, these laws and regulations could change in ways that substantially increase the Company’s costs. The Company cannot be certain that existing laws, regulations or standards, as currently interpreted or reinterpreted in the future, or future laws and regulations will not have a material adverse effect on its business, results of operations and financial condition. For more information, see Item 1. “Government Regulation—Environmental Compliance.”

Emergency response revenues are subject to significant volatility. Environmental Services’ response revenues and profitability are event driven and can vary greatly from quarter-to-quarter and year-to-year based on the number and magnitude of responses.

A change in oil spill regulation could reduce demand for Environmental Services’ emergency response services. Environmental Services is dependent upon regulations promulgated under OPA 90, international conventions and, to a lesser extent, local regulations. A change in emergency regulations and/or increased competition from non-profit competitors could decrease demand for Environmental Services’ emergency response services and/or increase costs without a commensurate increase in revenue.

A relaxation of oil spill regulation or enforcement could reduce demand for Environmental Services’ emergency response services. Environmental Services is dependent upon the enforcement of regulations promulgated under OPA 90, international conventions and, to a lesser extent, local regulations. Less stringent emergency regulations or less aggressive enforcement of these regulations could decrease demand for Environmental Services’ emergency response services. There can be no assurance that oil spill regulation will not be relaxed or enforcement of existing or future regulation will not become less stringent. If this happens, the demand for Environmental Services’ emergency response services could be adversely impacted.

A change in, or revocation of, National Response Corporation’s classification as an Oil Spill Removal Organization could result in a loss of business. The National Response Corporation (“NRC”) is classified by the USCG as an Oil Spill Removal Organization (“OSRO”). The USCG classifies OSROs based on their overall ability to respond to various types and sizes of oil spills. USCG-classified OSROs have a competitive advantage over non-classified service providers because customers of a classified OSRO are exempt from regulations that would otherwise require them to list their oil spill response resources in filings with the USCG. A loss of NRC’s classification or changes in the requirements for classification could eliminate or diminish NRC’s ability to provide customers with this exemption. If this happens, Environmental Services could lose customers.

32

Environmental Services could incur liability in connection with providing spill response services. Although Environmental Services is generally exempt in the United States from liability under the CWA for its own actions and omissions in providing spill response services, this exemption might not apply if it were found to have been grossly negligent or to have engaged in willful misconduct, or if it were to have failed to provide these services consistent with applicable regulations and directives under the CWA. In addition, the exemption under the federal CWA would not protect Environmental Services against liability for personal injury or wrongful death, or against prosecution under other federal or state laws. Although most of the states within the United States in which Environmental Services provides services have adopted similar exemptions, several states have not. If a court or other applicable authority were to determine that Environmental Services does not benefit from federal or state exemptions from liability in providing emergency response services, Environmental Services could be liable together with the local contractor and the responsible party for any resulting damages, including damages caused by others. In the international market, Environmental Services does not benefit from the spill response liability protection provided by the CWA and therefore is subject to the liability terms and conditions negotiated with its international clients.

Inland River Services could experience variation in freight rates. Freight transportation rates may fluctuate as the volume of cargo and availability of barges changes. The volume of freight transported on the Inland River Waterways may vary as a result of various factors, such as global economic conditions and business cycles, domestic and international agricultural production and demand, and foreign currency exchange rates. Barge participation in the industry can also vary year-to-year and is dependent on the number of barges built and retired from service. Extended periods of high barge availability and low cargo demand could adversely impact Inland River Services.

Inland River Services’ results of operations could be adversely affected by the decline in U.S. grain exports. Inland River Services’ business is significantly affected by the volume of grain exports handled through ports in the U.S. Gulf of Mexico. Grain exports can vary due to a number of factors including crop harvest yield levels in the United States and abroad, and the demand for grain in the United States. A shortage of available grain overseas can increase demand for U.S. grain. Conversely, an abundance of grain overseas can decrease demand for U.S. grain. A decline in exports could result in excess barge capacity, which would likely lower freight rates earned by Inland River Services.

Inland River Services’ results of operations could be adversely affected by international economic and political factors. The actions of foreign governments could affect the import and export of the dry-bulk commodities typically transported by Inland River Services. Foreign trade agreements and each country’s adherence to the terms of such agreements can raise or lower demand for U.S. imports and exports of the dry-bulk commodities that Inland River Services transports. National and international boycotts and embargoes of other countries’ or U.S. imports or exports together with the raising or lowering of tariff rates could affect the demand for the transportation of cargos handled by Inland River Services. These actions or developments could have an adverse impact on Inland River Services.

Inland River Services’ results of operations are affected by seasonal activity. Inland River Services’ business is seasonal, and its quarterly revenues and profits have historically been lower in the first and second quarters of the year and higher in the third and fourth quarters, during the grain harvest.

Inland River Services’ results of operations are affected by adverse weather and river conditions. Weather patterns can affect river levels and cause ice conditions during winter months, which can hamper barge navigation. Locks and dams on river systems may be closed for maintenance or other causes, which may delay barge movements. These conditions could adversely impact Inland River Services.

The aging infrastructure on the U.S. Inland River Waterways may lead to increased costs and disruptions in Inland River Services’ operations. Many of the locks and dams on the U.S. Inland River Waterways were built early in the last century, and their age makes them costly to maintain and susceptible to unscheduled maintenance outages. Delays caused by malfunctioning locks and dams could increase Inland River Services’

33

operating costs and delay the delivery of cargos. Moreover, in the future, increased diesel fuel user taxes could be imposed to fund necessary infrastructure improvements, and such increases may not be recoverable by Inland River Services through pricing increases.

Inland River Services’ results of operations could be materially and adversely affected by fuel price fluctuations. For the most part, Inland River Services purchases towboat and fleeting services from third party vendors. The price of these services can rise when fuel prices escalate and could adversely impact Inland River Services’ results of operation.

The Company’s insurance coverage may be inadequate to protect it from the liabilities that could arise in its businesses. Although the Company maintains insurance coverage against the risks related to its businesses, risks may arise for which the Company may not be insured. Claims covered by insurance are subject to deductibles, the aggregate amount of which could be material. Insurance policies are also subject to compliance with certain conditions, the failure of which could lead to a denial of coverage as to a particular claim or the voiding of a particular insurance policy. There also can be no assurance that existing insurance coverage can be renewed at commercially reasonable rates or that available coverage will be adequate to cover future claims. If a loss occurs that is partially or completely uninsured, the Company could be exposed to substantial liability.

The Company’s global operations are subject to certain foreign currency, interest rate, fixed-income, equity and commodity price risks. The Company is exposed to certain foreign currency, interest rate, fixed-income, equity and commodity price risks. Some of these risks may be hedged, but fluctuations could impact the Company’s financial position and its results of operations. The Company has, and anticipates that it will continue to have, contracts denominated in foreign currencies. It is often not practicable for the Company to effectively hedge the entire risk of significant changes in currency rates during a contract period. The Company’s financial position and its results of operations have been negatively impacted for certain periods and positively impacted for other periods, and may continue to be affected to a material extent by the impact of foreign currency exchange rate fluctuations. The Company’s financial position and its results of operations may also be affected by the cost of hedging activities that the Company undertakes. The Company holds a large proportion of its net assets in cash equivalents and short-term investments, including a variety of public and private debt and equity instruments. Such investments subject the Company to risks generally inherent in the capital markets. Given the relatively high proportion of the Company’s liquid assets relative to its overall size, its financial position and its results of operations may be materially affected by the results of the Company’s capital management and investment activities and the risks associated with those activities. Volatility in the financial markets and overall economic uncertainty also increases the risk that the actual amounts realized in the future on the Company’s debt and equity instruments could differ significantly from the fair values currently assigned to them. In addition, changes in interest rates may have an adverse impact on the Company’s financial position and its results of operations.

Commodity Trading and Logistics’ results of operations may be materially adversely affected by the availability, demand and price of agricultural commodities, weather, disease, government programs, and competition. The availability and price of agricultural commodities may fluctuate widely due to unpredictable factors such as weather, plantings, government programs and policies, changes in global demand resulting from population growth and changes in standards of living, and global production of similar and competitive crops. Reduced supply of agricultural commodities due to weather-related factors or other reasons could adversely affect Commodity Trading and Logistics’ profitability. Reduced supplies of agricultural commodities could limit Commodity Trading and Logistics’ ability to procure, transport, store, process, and merchandise agricultural commodities in an efficient manner. In addition, the availability and price of agricultural commodities can be affected by other factors, such as plant disease, which can result in crop failures and reduced harvests.

Commodity Trading and Logistics’ is subject to economic downturns, political instability and other risks of doing business globally, which could adversely affect operating results. Commodity Trading and Logistics conducts its business in many countries and geographic areas, and plans to expand its business in emerging market areas such as Asia, Africa and parts of the Caribbean. Both developed and emerging market areas are

34

subject to economic downturns and emerging market areas could be subject to more volatile economic, political and market conditions. Such economic downturns and volatile conditions may have a negative impact on Commodity Trading and Logistics’ ability to execute its business strategies and on its financial position and its results of operations. Commodity Trading and Logistics’ results of operations could be affected by changes in trade, monetary and fiscal policies, laws and regulations, and other activities of governments, agencies, and similar organizations, including political conditions, trade regulations affecting production, pricing and marketing of products, local labor conditions and regulations, burdensome taxes and tariffs, enforceability of legal agreements and judgments, and other trade barriers.

Commodity Trading and Logistics is subject to government policies and regulations, in general, and specifically those affecting the agricultural sector and related industries, which could adversely affect its operating results. Agricultural production and trade flows are subject to government policies and regulations. Governmental policies affecting the agricultural industry, such as taxes, tariffs, duties, subsidies, incentives and import and export restrictions on agricultural commodities and commodity products, can influence the planting of certain crops, the location and size of crop production, whether unprocessed or processed commodity products are traded, the volume and types of imports and exports, the availability and competitiveness of feedstocks as raw materials, and industry profitability. In addition, international trade disputes can adversely affect agricultural commodity trade flows by limiting or disrupting trade between countries or regions. Future government policies may adversely affect the supply of, demand for, and prices of Commodity Trading and Logistics’ products, restrict its ability to do business in its existing and target markets, and negatively impact revenues and operating results.

Commodity Trading and Logistics is subject to numerous laws and regulations globally that could adversely affect operating results. Commodity Trading and Logistics is required to comply with the numerous and broad reaching laws and regulations administered by United States federal, state, local, and foreign governmental agencies relating to, but not limited to, the sourcing, transporting, storing and merchandising of agricultural commodities and products. Any failure to comply with applicable laws and regulations could subject Commodity Trading and Logistics to administrative penalties and injunctive relief, civil remedies, including fines, injunctions, and recalls of its products.

Commodity Trading and Logistics’ risk management strategies may not be effective. Commodity Trading and Logistics business is affected by counterparty risk including non-performance by suppliers, vendors and counterparties, fluctuations in agricultural commodity prices, transportation costs, energy prices, interest rates, and foreign currency exchange rates. Although Commodity Trading and Logistics may engage in hedging transactions to manage these risks, such transactions may not be successful in mitigating its exposure to these fluctuations and may adversely affect operating results.

The Company’s inability to attract and retain qualified personnel could have an adverse effect on its business. Attracting and retaining skilled personnel across all of the Company’s business segments is an important factor in its future success. The market for the personnel employed is highly competitive and the Company cannot be certain that it will be successful in attracting and retaining qualified personnel in the future.

The failure to successfully complete construction or conversion of the Company’s vessels, repairs, maintenance or routine drydockings on schedule and on budget could adversely affect the Company’s financial position and its results of operations. From time to time, the Company may have a number of vessels under conversion and may plan to construct or convert other vessels in response to current and future market conditions. The Company also routinely engages shipyards to drydock vessels for regulatory compliance and to provide repair and maintenance. Construction and conversion projects and drydockings are subject to risks of delay and cost overruns, resulting from shortages of equipment, lack of shipyard availability, unforeseen engineering problems, work stoppages, weather interference, unanticipated cost increases, inability to obtain necessary certifications and approvals and shortages of materials or skilled labor. A significant delay in either construction or drydockings could have a material adverse effect on contract commitments and revenues with

35

respect to vessels under construction, conversion or undergoing drydockings. Significant cost overruns or delays for vessels under construction, conversion or retrofit could also adversely affect the Company’s financial position and its results of operations.

A Violation of the Foreign Corrupt Practices Act may adversely affect the Company’s business and operations. 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, the Company is 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 maintaining business. The Company has adopted stringent procedures to enforce compliance with the FCPA, but it may be held liable for actions taken by its strategic or local partners even though these partners may not be subject to the FCPA. Any determination that the Company has violated the FCPA could have a material adverse effect on its business and results of operations.

An outbreak of any contagious disease, such as H1N1 Flu, may adversely affect the Company’s business and operations. The outbreak of diseases, such as H1N1 Flu, commonly referred to as Swine Flu, has curtailed and may curtail travel to and from certain countries, or geographic regions. Restrictions on travel to and from these countries or other regions due to additional incidences for diseases, such as Swine Flu, could have a material adverse effect on the Company’s business, financial position or its results of operations.

There are risks associated with climate change and environmental regulations. Governments around the world have, in recent years, placed increasing attention on matters affecting the environment and this could lead to new laws or regulations pertaining to climate change, carbon emissions or energy use that in turn could result in a reduction in demand for hydrocarbon-based fuel. Governments could also pass laws or regulations encouraging or mandating the use of alternative energy sources such as wind power and solar energy, which may reduce demand for oil and natural gas and therefore the services provided by the Company. Such initiatives could have a material adverse effect on the Company’s financial position and its results of operations.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 2. PROPERTIES

Offshore support vessels, helicopters, inland river towboats and barges, and tankers are the principal physical properties owned by the Company and are more fully described in “Offshore Marine Services,” “Aviation Services,” “Inland River Services” and “Marine Transportation Services” and in “Item 1. Business.”

ITEM 3. LEGAL PROCEEDINGS

During 2006 and 2007, Marine Transportation Services (“MTS”) had two of its tankers retrofitted to a double-hull configuration in a foreign shipyard to enable each of them to continue to transport crude oil and petroleum products beyond their OPA 90 mandated retirement dates in 2011. Both vessels operate in the U.S. coastwise trade that, under the Shipping Acts, is restricted to vessels built or rebuilt in the United States. In May 2005, MTS received a determination from the U.S. Coast Guard (“USCG”), which administers the United States build requirements of the Shipping Acts, concluding the retrofit work would not constitute a foreign rebuilding and therefore would not jeopardize the tankers’ eligibility to operate in the U.S. coastwise trade. MTS completed the retrofit work in the foreign shipyard in reliance upon the USCG’s determination, which MTS believes was correct and in accord with the USCG’s long-standing regulations and interpretations. On July 9, 2007, a U.S. shipbuilders trade association and two operators of tankers in the U.S. coastwise trade (“Shipbuilders”) commenced a civil action in the U.S. District Court for the Eastern District of Virginia, Shipbuilders Council of America, Inc., et al. v. U.S. Department of Homeland Security, et al., No. 1:07cv665 (E.D. Va.) (the “SB Trader Litigation”), in which they sought to have the court set aside the USCG’s determination and direct the USCG to

36

revoke the coastwise license of one of the two retrofitted tankers, the Seabulk Trader. MTS intervened in the action to assist the USCG in defending its determination. On April 24, 2008, the Court issued a Memorandum Opinion granting a motion for summary judgment by Shipbuilders setting aside the USCG’s determination and remanding the matter to the USCG for further proceedings with instructions to revoke the coastwise endorsement of the Seabulk Trader. On April 30, 2008, MTS appealed the decision to the U.S. Court of Appeals for the Fourth Circuit (the “Court of Appeals”), and the lower court’s decision was stayed pending appeal, subject to certain terms (which MTS also separately appealed). Those terms required that MTS pay to the plaintiffs 12.5% of the revenue generated by the Seabulk Trader from November 7, 2008 in the event that the Court of Appeals affirms the lower court’s decision to revoke its coastwise endorsement (the “Undertaking”). On July 2, 2008, Shipbuilders commenced a second civil action in the U.S. District Court for the Eastern District of Virginia, entitled Shipbuilders Council of America, Inc., et al. v. U.S. Department of Homeland Security, et al., No. 1:08cv680 (E.D. Va.) (the “SB Challenge Litigation”), alleging essentially identical claims as those asserted in the SB Trader Litigation against MTS’s second retrofitted tanker, the Seabulk Challenge. MTS has intervened in the SB Challenge Litigation that was stayed pending the decision of the Court of Appeals in the SB Trader Litigation. In September 2009, the Court of Appeals reversed the District Court, holding that the USCG’s interpretation was correct and that the District Court erred in requiring MTS to provide the Undertaking. On January 19, 2010, the District Court vacated its April 24, 2008 Order to the extent it directed the USCG to revoke the coastwise endorsement for the Seabulk Trader and remanded the matter to the USCG with instructions to (i) provide a fuller explanation of one aspect of its rebuild decision and (ii) consider further whether certain work relating to the vessel’s segregated ballast tanks constituted a prohibited foreign installation of required segregated ballast tanks. On August 31, 2010, the USCG issued a further determination further explaining its rebuild decision and concluding that the work relating to the vessel’s segregated ballast tanks did not constitute the installation of a required segregated ballast tank. One of the three plaintiffs in the District Court litigation urged the USCG to reach a contrary result with respect to the segregated ballast work, and it is possible that the plaintiff will ask the District Court to set aside this aspect of the USCG’s decision as well. The loss of coastwise eligibility for its two retrofitted tankers could lead to impairment concerns and could adversely affect the Company’s financial condition and its results of operations. The aggregate carrying value of the Company’s two retrofitted tankers was $46.0 million as of December 31, 2010 and such tankers contributed operating revenues of $19.8 million during the year ended December 31, 2010.

On June 12, 2009, a purported civil class action was filed against SEACOR, Era Group Inc., Era Aviation, Inc., Era Helicopters LLC and two other defendants (collectively the “Defendants”) in the U.S. District Court for the District of Delaware, Superior Offshore International, Inc. v. Bristow Group Inc., et al., No. 09-CV-438 (D.Del.). SEACOR acquired Era Group Inc., Era Aviation, Inc., and Era Helicopters LLC in December 2004. The complaint alleges that the Defendants violated federal antitrust laws by conspiring with each other to raise, fix, maintain or stabilize prices for offshore helicopter services in the U.S. Gulf of Mexico during the period January 2001 to December 2005. The purported class of plaintiffs includes all direct purchasers of such services and the relief sought includes compensatory damages and treble damages. On September 14, 2010, the District Court entered an order dismissing the complaint. On November 30, 2010, the District Court granted the plaintiffs motion for reconsideration and amendment (the “Motions”), and ordered limited discovery strictly in regard to the allegations set forth on the plaintiff’s amended complaint. The limited discovery was completed and the defendants have filed a motion for summary judgment, which is pending. The Company is unable to estimate the potential exposure, if any, resulting from these claims but believes they are without merit and intends to vigorously defend the action.

On July 14, 2010, a group of individuals and entities purporting to represent a class commenced a civil action in the U.S. District Court for the Eastern District of Louisiana, Terry G. Robin, et al. v. Seacor Marine, L.L.C., et al., No. 2:10-cv-01986 (E.D. La.), in which they assert that support vessels, including vessels owned by the Company, responding to the explosion and resulting fire that occurred aboard the semi-submersible drilling rig, the Deepwater Horizon, were negligent in their efforts to save lives and put out the fire and contributed to the sinking of the Deepwater Horizon and subsequent oil spill. The action now is part of the overall multi-district litigation, In re Oil Spill by the Oil Rig “Deepwater Horizon”, MDL No. 2179. The complaint seeks

37

compensatory, punitive, exemplary, and other damages. The Company believes that this lawsuit brought by class action lawyers targeting emergency responders acting under the direction of the U.S. Coast Guard has no merit and will seek its dismissal. The Company also recently filed petitions seeking exoneration from or limitation of liability in relation to any actions that may have been taken by vessels owned by the Company to extinguish the fire. Pursuant to the Limitation of Liability Act, those petitions impose an automatic stay on the Robin case, and the court has set a deadline of April 20, 2011 for individual claimants to assert claims in the limitation cases.

On July 20, 2010, two individuals purporting to represent a class commenced a civil action in the Civil District Court for the Parish of Orleans in the State of Louisiana, John Wunstell, Jr. and Kelly Blanchard v. BP, et al., No. 2010-7437 (Division K) (the “Wunstell Action”), in which they assert, among other theories, that Mr. Wunstell suffered injuries as a result of his exposure to certain noxious fumes and chemicals in connection with the provision of remediation, containment and response services by O’Brien’s Response Management Inc. (“O’Brien’s), a subsidiary of SEACOR. The action now is part of the overall multi-district litigation, In re Oil Spill by the Oil Rig “Deepwater Horizon”, MDL No. 2179. The complaint also seeks to establish a “class-wide court-supervised medical monitoring program” for all individuals “participating in BP’s Deepwater Horizon Vessels of Opportunity Program and/or Horizon Response Program” who allegedly experience injuries similar to Mr. Wunstell. The Company believes this lawsuit has no merit and will seek its dismissal. Pursuant to contractual agreements with the responsible party, the responsible party has agreed, subject to certain potential limitations, to indemnify and defend O’Brien’s in connection with the Wunstell Action and claims asserted in the MDL.

On December 15, 2010, SEACOR subsidiaries O’Brien’s and National Response Corporation (“NRC”) were named as defendants in one of the several consolidated “master complaints” that have been filed in the overall multi-district litigation, In re Oil Spill by the Oil Rig “Deepwater Horizon”, MDL No. 2179. The master complaint naming O’Brien’s and NRC asserts various claims on behalf of a punitive class against multiple defendants concerning the clean-up activities generally, and the use of dispersants specifically. By court order the Wunstell Action has been stayed as a result of the filing of the referenced master complaint. The Company believes that the claims asserted against its subsidiaries in the master complaint have no merit and will seek dismissal of the master complaint against both O’Brien’s and NRC. In addition to the indemnity provided to O’Brien’s, the Company has also sought indemnity from the responsible party pursuant to certain contractual arrangements for the claims asserted against NRC in the MDL.

In the normal course of its business, the Company becomes involved in various other litigation matters including, among other things, claims by third parties for alleged property damages and personal injuries. Management has used estimates in determining the Company’s potential exposure to these matters and has recorded reserves in its financial statements related thereto where appropriate. It is possible that a change in the Company’s estimates of that exposure could occur, but the Company does not expect that any such change in estimated costs would have a material effect on the Company’s consolidated financial position or its results of operations.

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

Overview

SEACOR and its subsidiaries are in the business of owning, operating, investing in and marketing equipment, primarily in the offshore oil and gas, industrial aviation and marine transportation industries. The Company conducts its activities in six primary business segments:

Offshore Marine Services operates a diversified fleet of offshore support vessels primarily servicing offshore oil and gas exploration, development and production facilities worldwide.

Aviation Services operates and leases helicopters that provide transportation services supporting offshore oil and gas activities primarily in the United States, air medical services to hospitals in the United States, and international leasing activities.

Inland River Services is primarily engaged in dry and liquid cargo transportation on the U.S. Inland River Waterways and the Gulf Intracoastal Waterways for a range of agricultural and industrial products.

Marine Transportation Services operates a fleet of U.S.-flag product tankers carrying petroleum, crude oil and chemical products in the U.S. coastwise trade.

Environmental Services is primarily engaged in the provision of emergency preparedness and response services to oil, chemical, industrial and marine transportation clients in the United States and abroad.

Commodity Trading and Logistics is an integrated business involved in the purchase, storage, transportation and sale of agricultural and energy commodities.

Other primarily includes Harbor and Offshore Towing Services, various other investments in joint ventures, primarily providing industrial air services, and lending and leasing activities.

The Company’s business segments, with the exception of Environmental Services and Commodity Trading and Logistics, are “asset related” and highly capital-intensive. Demand for the Company’s assets is cyclical in varying degrees due to fluctuations in the activity levels in the industries serviced by those assets, as well as availability of supply.

To manage capital successfully over time, the Company continually assesses its asset portfolio and pursues opportunities to realize value from its assets by shifting their operation to other markets or trading them when circumstances warrant. The Company actively leases out and leases in, and buys and sells equipment in the ordinary course of its business. It also designs, orders, builds, upgrades, operates or re-sells newly constructed equipment. The Company typically pursues a strategy of shedding older assets while adjusting its asset mix. The Company also leases assets to other operators and sells assets to financial lessors and leases them back for varying periods of time. The Company believes that maintaining significant liquidity is an important factor that will enable it to take advantage of opportunities as they arise.

In recent years, the Company has sought to create balance in its businesses and broaden its asset base by investing outside the oil and gas industry in barges, ships and tugs, and by looking for opportunities to engage in logistics support for movement of agricultural and energy commodities.

The Company is exploring opportunities to extend its industrial aviation activities through investments in sales, marketing and distribution of aircraft and specialized parts and services, maintenance and repair facilities and fixed base operations. In addition, the Company continues to look to expand in the Chinese and Indian markets.

45

The Company believes that demand for its barges, tankers and tugs is, in part, linked to different factors than those that drive demand for offshore oil and gas exploration and development. In addition, for barges and tankers, contracts can sometimes be secured with longer terms than those typically available for offshore marine and helicopter services. The expectation is that over time this strategy of diversification will provide better returns on capital than could be achieved by restricting investment to one specific, highly cyclical, asset class such as vessels supporting offshore oil and gas activity. The Company believes this strategy will afford more opportunities to use capital efficiently, create greater stability of earnings and allow improved margins due to operational synergies that in turn, should yield a lower cost of capital, more sustainable cash flows and increased profitability.

Deepwater Horizon Oil Spill Response

The Company’s operating results for the year ended December 31, 2010 were significantly impacted by oil spill response activities relating to the BP Macondo well incident in the U.S. Gulf of Mexico following the sinking of the semi-submersible drilling rig Deepwater Horizon in April 2010 (the “Oil Spill Response”). At the height of the Oil Spill Response, four of the Company’s business segments were actively providing support. Environmental Services provided (i) equipment and people to support clean-up activities on-shore, (ii) professional assistance, consulting services and software systems in support of incident management activities at various strategic locations, and (iii) assistance in the provision of manpower for clean-up operations throughout the region. Offshore Marine Services provided (i) vessels for a variety of functions including vessel decontamination, skimming, lightering, offshore traffic control and accommodation, and (ii) technical and video equipment on vessels engaged in the response to allow for instant tracking of assets and surveillance of operations. Aviation Services provided (i) helicopters for air support to U.S. Coast Guard observers undertaking oil spotting and assessment missions, (ii) transportation for various other officials requiring overflights to assess the response and recovery efforts, and (iii) a flight tracking system to monitor the movement of all marine and aviation assets involved in the response. Harbor and Offshore Towing Services provided tugs engaged in the decontamination of vessels transiting the region. Oil Spill Response activity has significantly diminished since December 31, 2010. The Company’s remaining involvement consists of limited professional services provided by Environmental Services.

As an active party to the Oil Spill Response, the Company has been named in individual and class action litigations involving environmental damage, business and personal injury claims that may result in financial exposure. In reaction to the Deepwater Horizon/BP Macondo well incident, the U.S. Department of the Interior issued an order on May 28, 2010 imposing a six month moratorium on all offshore deepwater drilling projects. A preliminary injunction was issued on June 22, 2010 blocking enforcement of the moratorium; however, the U.S. Department of Interior issued a new moratorium on July 12, 2010 which was lifted on October 12, 2010. The U.S. Department of Interior has also implemented additional safety and certification requirements for drilling activities, imposed additional requirements for the approval of development and production activities, and delayed the approval of applications to drill in both deepwater and shallow-water areas. The Company’s results, in particular those of its Offshore Marine Services and Aviation Services segments, could be adversely impacted as a consequence of reduced drilling activities in the U.S. Gulf of Mexico. For additional information, see “Item 1A. Risk Factors” and “Item 3. Legal Proceedings” included in Part I of this Annual Report on Form 10-K.

Consolidated Results of Operations

Consolidated financial data for segment and geographic areas is reported in Part IV “Note 15. Major Customers and Segment Information” of this Annual Report on Form 10-K.

Offshore Marine Services

The market for offshore oil and gas drilling has historically been cyclical. Demand tends to be linked to the price of oil and gas and those prices tend to fluctuate depending on many factors, including global economic

46

activity and levels of inventory. Price levels for oil and gas can in themselves cause additional fluctuations by inducing changes in consumer behavior. The cyclicality of the market is further exacerbated by the tendency in the industry to order capital assets as demand grows, often resulting in new capacity becoming available just as demand for oil and gas is peaking and activity is about to decline.

In late 2008, offshore activity began to decline following a sharp reduction in oil and gas prices. The decline continued throughout 2009 into 2010 and the market was further weakened by overcapacity, particularly internationally, following ongoing deliveries of newly built vessels. This situation is likely to continue into 2011, although the rate of new deliveries should begin to slow down during the second half of the year. The dynamics of the U.S. Gulf of Mexico market were significantly impacted by the sinking of the Deepwater Horizon in April 2010. The subsequent Oil Spill Response created an immediate demand for most vessel types from May until October 2010. At its peak, the Company had 22 vessels deployed on the response. Beyond this short term increase in activity, the U.S. Government imposed moratorium on certain drilling activities has caused a significant decline in demand for all vessel types. Although the moratorium has now been lifted, the revised requirements of the deepwater drilling permit process has created a stagnant environment. This situation is expected to continue in the immediate term. The Company responded to the weak market conditions by cold-stacking a number of vessels in the U.S. Gulf of Mexico. As of December 31, 2010, the Company had 13 vessels cold-stacked in the U.S. Gulf of Mexico. The term ‘cold-stacked’ means unmanned and not working. The Company continues to monitor market conditions and will cold-stack additional vessels, or place vessels back into service, as it deems appropriate. The continued flow of newly built vessels into the international market has created a situation of oversupply in the North Sea, Asia, Middle East and West Africa regions. This situation is expected to continue throughout 2011.

Reduced activity, combined with tighter capital and credit markets, has created uncertainty over new construction of offshore equipment. The order book for new equipment remains large but there are uncertainties as to if and when these assets will be delivered. Many of these assets were ordered without firm contractual commitments for employment and should these assets be delivered and placed into service there could be an adverse impact on market conditions.

Over the last several years, Offshore Marine Services has disposed of its old generation equipment while taking delivery of new vessels specifically designed to meet the changing requirements of the market. Since December 31, 2005, the average age of the fleet, excluding standby safety vessels, has been reduced from 15.5 years to 11.5 years. Offshore Marine Services enters 2011 with a limited order book for new equipment and believes its diverse fleet and broad geographical distribution of vessels will assist in weathering the effects of the industry downturn. The Company’s strong financial position should enable Offshore Marine Services to capitalize on opportunities as they develop for purchasing, mobilizing or upgrading vessels to meet changing market conditions. As of December 31, 2010, Offshore Marine Services had three vessels (one Anchor Handling Tug Supply and two Fast Support) under construction in the U.S. Gulf of Mexico.

The number and type of vessels operated, their rates per day worked and their utilization levels are the key determinants of Offshore Marine Services’ operating results and cash flows. Unless a vessel is cold-stacked (removed from operational service), there is little reduction in daily running costs and, consequently, operating margins are most sensitive to changes in rates per day worked and utilization.

The aggregate cost of Offshore Marine Services’ operations depends primarily on the size and asset mix of the fleet. Offshore Marine Services’ operating costs and expenses are grouped into the following categories:

• personnel (primarily wages, benefits, payroll taxes, savings plans and travel for marine personnel);

• repairs and maintenance (primarily routine repairs and maintenance and main engine overhauls which are performed in accordance with planned maintenance programs);

• drydocking (primarily the cost of regulatory drydockings performed in accordance with applicable regulations);

47

• insurance and loss reserves (primarily the cost of Hull and Machinery and Protection and Indemnity insurance premiums and loss deductibles);

• fuel, lubes and supplies;

• leased-in equipment (includes the cost of leasing vessels from lessors under bareboat charter arrangements and leasing equipment employed on vessels);

• brokered vessel activity (the cost of chartering-in third party vessels under time charter arrangements to fulfill a customer requirement that cannot be filled by a Company owned or managed vessel); and

• other (communication costs, expenses incurred in mobilizing vessels between geographic regions, third party shipmanagement fees, freight expenses, customs and importation duties, and other).

The Company expenses drydocking, engine overhauls and vessel mobilization costs as incurred. If a disproportionate number of drydockings, overhauls or mobilizations are undertaken in a particular fiscal year or quarter, operating expenses may vary significantly when compared with the prior year or prior quarter.

2010 compared with 2009

Operating Revenues. Time charter revenues were $39.9 million lower. Overall fleet utilization was 75% compared with 73%. The number of days available for charter was 48,378 compared with 55,516, a reduction of 7,138 days or 13%, due to net fleet dispositions and termination of leases, which resulted in returning to lessors seven and eleven vessels operating in the U.S. Gulf of Mexico in 2010 and 2009, respectively. Overall average day rates were $12,499 per day compared with $12,223 per day, an increase of $276 per day or 2%. Net fleet dispositions reduced time charter revenues by $37.3 million while changes in utilization, average day rates, the

50

impact of vessels mobilizing between geographic regions and other changes in fleet mix combined to reduce time charter revenues by $1.8 million. In overall terms, the impact of unfavorable changes in currency exchange rates decreased time charter revenues by $0.8 million.

In the U.S. Gulf of Mexico, time charter revenues were $23.8 million higher primarily as a result of demand for vessels in support of the Oil Spill Response. During 2010, Offshore Marine Services had as many as 22 vessels supporting the Oil Spill Response, although as of December 31, 2010, all vessels had been released. Charters in support of the Oil Spill Response contributed $90.3 million of time charter revenues in 2010. In overall terms, time charter revenues increased by $19.0 million due to improved fleet utilization and higher average day rates, decreased by $12.0 million due to net fleet dispositions and the impact of vessels mobilizing between geographic regions, and increased $16.8 million due to changes in fleet mix. As of December 31, 2010, the Company had 13 vessels cold-stacked in this region compared with 19 as of December 31, 2009.

In Africa, time charter revenues were $30.2 million lower. Net fleet dispositions, vessels that mobilized to other geographic regions and changes in fleet mix combined to reduced time charter revenues by $15.9 million. Lower average day rates and more off-hire time due to softer market conditions reduced time charter revenues by $14.3 million.

In the Middle East, time charter revenues were $14.1 million lower, of which $3.5 million was due to net fleet dispositions, $3.9 million was due to out-of-service time for one vessel undergoing conversion to a safety standby configuration, and $8.9 million was due to lower average day rates and more off-hire time attributable to softer market conditions. Vessels that mobilized into the region and changes in fleet mix contributed time charter revenues of $2.2 million.

In Mexico, Central and South America, time charter revenues were $7.8 million lower. Net fleet dispositions reduced time charter revenues by $9.8 million while vessels that mobilized into the region and changes in fleet mix contributed time charter revenues of $3.1 million. More off-hire time attributable to softer market conditions, partially offset by increases in average day rates, reduced time charter revenues by $1.1 million.

In the United Kingdom, time charter revenues were $0.1 million higher. The commencement of a new charter for a vessel mobilized into the region contributed additional time charter revenues of $1.7 million. Additional off-hire time, primarily due to increased drydocking activity, lower average day rates, and a weakening in the pound sterling against the U.S. dollar reduced time charter revenues by $1.6 million.

In Asia, time charter revenues were $11.7 million lower, of which $9.8 million was attributable to fleet dispositions. Reduced fleet utilization and lower average day rates combined to reduce time charter revenues by $2.4 million. Vessels that mobilized into the region contributed time charter revenues of $0.5 million.

Revenues from brokered vessel activity were $14.5 million lower primarily due to reduced activity in the Middle East. Other marine services revenues were $8.9 million higher primarily due to services provided in connection with the Oil Spill Response.

Costs and Expenses. Operating expenses were $17.3 million lower due to net fleet dispositions and $14.3 million lower due to reduced brokered vessel activity in the Middle East. These reductions in operating expenses were primarily offset by higher personnel costs, higher drydocking expense, and other costs associated with the Oil Spill Response. Personnel costs in 2010 included a $7.8 million expense for the Company’s share of a funding deficit of the United Kingdom Merchant Navy Officers’ Pension Fund and a $3.3 million expense for the settlement of litigation. Repair and maintenance expenses were $5.7 million lower primarily due to net fleet dispositions and lower expenses related to the Company’s Anchor Handling Towing Supply vessels operating in the U.S. Gulf of Mexico. Drydocking expense was $6.7 million higher due to increased activity, particularly in the North Sea. Other operating expenses were $7.0 million higher primarily due to services provided in connection with the Oil Spill Response.

51

Gains on Asset Dispositions and Impairments, Net. Gains on asset dispositions were $7.0 million higher in 2010 compared with 2009. Gains in 2010 included the sale of eight offshore support vessels.

2009 compared with 2008

Operating Revenues. Time charter revenues were $155.2 million lower. Overall fleet utilization was 73% compared with 83%. The number of days available for charter in 2009 was 55,516 compared with 63,227, a reduction of 7,711 days or 12%, due to net fleet dispositions, including the return of eleven vessels operating in the U.S. Gulf of Mexico to leasing companies in 2009. Overall average day rates were $12,223 per day compared with $12,396 per day, a decrease of $173 per day or 1%. Net fleet dispositions, changes in utilization, the impact of vessels mobilizing between geographic regions and other changes in fleet mix combined to reduce time charter revenue by $113.8 million. In overall terms, lower average day rates and unfavorable changes in currency exchange rates reduced time charter revenues by $41.4 million.

In the U.S. Gulf of Mexico, time charter revenues were $129.0 million lower primarily due to reduced fleet utilization, net fleet dispositions and lower average day rates. In overall terms, time charter revenues decreased by $19.0 million due to lower average day rates, $89.0 million due to reduced fleet utilization, and $21.0 million due to net fleet dispositions, the impact of vessels mobilizing between geographic regions, and other changes in fleet mix. As of December 31, 2009, 19 of the Company’s vessels were cold-stacked in this region.

In Africa, time charter revenues were $22.4 million lower, of which $6.9 million was attributable to net fleet dispositions and $10.2 million was due to vessels mobilizing to other geographic regions. The remaining difference of $5.3 million was primarily due to reduced fleet utilization.

In the Middle East, time charter revenues were $3.5 million lower. Net fleet dispositions reduced time charter revenues by $9.2 million. Vessels that mobilized into the region contributed time charter revenues of $7.9 million. The remaining decrease of $2.2 million was due to reduced fleet utilization.

In Mexico, Central and South America, time charter revenues were $2.4 million higher, of which $1.7 million was due to the combined effect of improvements in fleet utilization and average day rates and $1.3 million was due to a change in contract status for two vessels from bareboat charter to time charter. Time charter revenues decreased by $0.6 million due to net fleet dispositions and the impact of vessels mobilizing to other geographic regions.

In the United Kingdom, time charter revenues were $6.6 million lower, of which $11.8 million was due to a weakening of the pound sterling against the U.S. dollar. The acquisition of one vessel during 2009 and improvements in average day rates contributed additional time charter revenues of $2.8 million and $2.4 million, respectively.

In Asia, time charter revenues were $3.8 million higher primarily due to vessels mobilizing into the region, partially offset by net fleet dispositions.

Revenues from brokered vessel activity were $5.5 million higher primarily due to increased activity in West Africa. Bareboat charter revenues were $1.6 million lower primarily due to the sale during 2009 of vessels which had been operating on bareboat charters. Other marine services were $4.9 million higher, primarily due to a $3.0 million increase in third party shipmanagement fees.

Costs and Expenses. Operating expenses decreased by $80.5 million primarily due to net fleet dispositions, the cold-stacking of vessels in the U.S. Gulf of Mexico, and reduced drydocking, repair and maintenance expense. General and administrative expenses were $11.4 million lower primarily due to restructuring of the international group in late 2008.

Gains on Asset Dispositions and Impairments, Net. Gains on asset dispositions were $46.7 million lower in 2009 compared with 2008. Gains in 2009 included the sale of 19 offshore support vessels.

Aviation Services

A significant portion of Aviation Services’ operations involves transportation services provided to offshore oil and gas customers and leasing aircraft to third parties. As discussed in the Offshore Marine Services segment, the offshore oil and gas market is highly cyclical with demand linked to the price of oil and gas that tends to fluctuate depending on many factors, including global economic activity and levels of inventory. Alaska and the U.S. Gulf of Mexico represent Aviation Services’ major oil and gas markets.

During 2010, the market for Aviation Services’ assets in the United States was disrupted by the sinking of the Deepwater Horizon. In the short term, Aviation Services benefited by providing helicopters and software systems to support the Oil Spill Response efforts. At the same time however, the moratorium on certain offshore drilling projects caused a decrease in demand for helicopters supporting oil and gas activities. While the moratorium has now been lifted, the process of issuing permits to drill has slowed down and continues to have a negative impact on demand. Aviation Services does not expect the slowdown will have a significant impact on its future results as its activities are more dependent on longer-term production, maintenance and inspection work than short-term exploration and development projects. Exploration and development activities generally require medium size and heavy aircraft, which typically earn higher margins. Production related activities are less sensitive to variations in commodity prices and accordingly provide a more stable demand for services. Aviation Services has concentrated its production support in deepwater areas and with pipeline companies. It performs very little shallow water production support.

In recent years, Aviation Services’ offshore oil and gas customers have been seeking modern aircraft that offer enhanced safety features and greater performance. Some customers have also been moving from small single engine aircraft to small twin engine aircraft due to the additional safety afforded from two engines when flying extended range missions in deepwater areas.

Demand for leased aircraft is influenced by the overall demand for aircraft and the availability of financing to potential customers. The recent difficulties in the credit market have increased demand for Aviation Services’ leased assets.

Aviation Services, through one of its joint ventures, offer training services to third parties using a mix of classroom instruction, flight training devices and aircraft. The demand for these services has increased in line with customers efforts to improve safety.

The aggregate cost of Aviation Services’ operations depends primarily on the size and asset mix of the fleet. Aviation Services’ operating costs and expenses are grouped into the following categories:

• personnel (wages, benefits, payroll taxes, savings plans, training, crew subsistence and travel for aviation personnel);

• repairs and maintenance (primarily routine activities as well as aircraft refurbishments and engine and major component overhauls that are performed in accordance with planned maintenance programs);

• insurance and loss reserves (the cost of Hull and Machinery and Protection and Indemnity insurance premiums and loss deductibles);

• fuel;

• leased-in equipment (includes the cost of leasing helicopters and equipment); and

• other (primarily base expenses, property, sales and use taxes, communication costs, freight expenses, and other).

Certain third party vendors maintain the engines and certain components on some aircraft under programs that require Aviation Services to pay ratably for the service based on actual flight hours flown. The costs are

53

normally billed on a monthly basis and expensed as incurred. In the event that Aviation Services places an aircraft in a program after a maintenance period has begun, it may be necessary to pay an initial buy-in charge based on hours flown to date with such charge being amortized over the contract period. If an aircraft is sold before the scheduled maintenance work is carried out, Aviation Services may be able to recover part of its expenditure.

The Company expenses all maintenance and repair costs as incurred. Should Aviation Services exit from third party vendor maintenance programs or a disproportionate number of refurbishments or overhauls are undertaken in a particular fiscal year or quarter, operating expenses may vary significantly when compared with the prior year or prior quarter.

2010 compared with 2009

Operating Revenues. Operating revenues in the U.S. Gulf of Mexico were $8.9 million lower primarily due to a reduction in the number of aircraft operating in the region and lower flight hours supporting oil and gas activities following the Deepwater Horizon incident. These reductions were partially offset by revenues generated by equipment contracted to the U.S. Coast Guard in support of the Oil Spill Response. Operating revenues from leasing activities increased by $22.1 million as additional aircraft were placed on international leases, primarily in Brazil. As of December 31, 2010, 39 aircraft were dedicated to the leasing market compared with 35 as of December 31, 2009. Operating revenues from Air Medical Services decreased by $15.0 million due to the non-renewal of several contracts upon their conclusion.

Costs and Expenses. Personnel costs were $4.4 million lower primarily due to a reduction in workforce in Air Medical Services in line with reduced activity and lower crew subsistence costs in the U.S. Gulf of Mexico. These decreases were partially offset by higher wage and benefit costs in Alaska in support of additional

55

helicopters on contract. Repair and maintenance costs were $3.4 million higher as additional aircraft were placed in third party vendor maintenance support programs, partially offset by a reduction in maintenance spending in Air Medical Services as a result of fewer contracts. Fuel expense decreased $1.8 million primarily due to a reduction in FBO fuel sales. Other operating expenses were lower in 2009 due to the receipt of insurance reimbursements in 2009 for expenses incurred following Hurricanes Gustav and Ike in 2008. General and administrative expenses were $4.4 million higher primarily due to higher wage and benefit costs and the 2009 reversal of a $1.5 million provision for doubtful accounts following its collection. Depreciation and amortization expense was $6.0 million higher due to the continued modernization of the fleet through the addition of new and higher cost equipment.

2009 compared with 2008

Operating Revenues. Operating revenues were $13.3 million lower in the U.S. Gulf of Mexico primarily due to a slowdown in offshore oil and gas activity and a reduction in hurricane related activity. Operating revenues in Alaska increased by $5.5 million due to additional contract revenues generated from oil and gas support activities. Operating revenues from leasing activities increased by $8.5 million, primarily in international regions. As of December 31, 2009, 35 aircraft were dedicated to the leasing market compared with 24 as of December 31, 2008. Operating revenues from Air Medical Services decreased by $3.0 million, primarily due to contract terminations. Operating revenues from FBO decreased by $8.8 million primarily due to lower fuel prices charged and a reduction in activity.

Costs and Expenses. Personnel costs were $8.8 million lower primarily due to a reduction in workforce in both the U.S. Gulf of Mexico and Air Medical Services in line with the slow down in activity as discussed above. These reductions were partially offset by increased personnel costs in Alaska in support of additional contracts for oil and gas activity. Repair and maintenance costs were $1.5 million lower primarily due to the timing of repairs. Fuel expense decreased $18.5 million primarily due to the reduction in flight hours in the U.S. Gulf of Mexico and lower activity levels at the FBO following the loss of a significant customer. Other operating expenses were lower in 2009 due to the receipt of insurance reimbursements in 2009 for expenses incurred following Hurricanes Gustav and Ike in 2008.

Inland River Services

Historically, activity levels for grain exports and non-grain imports are the key drivers in determining freight rates. During 2010, grain exports were marginally higher than in 2009. Early in 2010, export demand for corn was weak due to cheaper feed grain availability elsewhere. This decrease in exports coupled with an oversupply of barges led to equipment being idled in the early spring. The market improved in the early summer as Asian demand for corn supported freight values and continued as drought conditions in Russia in late July further influenced demand. Market conditions during parts of 2010 resulted in more dry cargo barges earning demurrage. Imports were essentially flat, continuing at or near 2009 levels, in line with the ongoing economic recession in the United States with low levels of demand for construction related materials and other industrial cargos.

Weather conditions presented persistent challenges to the industry during 2010. At the start of the year, ice, fog and high water limited operations and caused delays on the Illinois and Lower Mississippi rivers. Another wet spring exacerbated the high water conditions and restricted tow sizes throughout much of the spring and early summer. In late summer, warm, dry weather throughout much of the Midwest allowed for ideal towing conditions but as the dry weather continued into the fall, water levels fell and river conditions deteriorated leading to restricted drafts. In December, winter arrived early and ice, low water and cold temperatures further hampered operating conditions.

At the end of 2010, the average age of the Inland River Services’ dry cargo barge fleet was 6 years old, which the Company believes is among the youngest fleets operating on the U.S. Inland River Waterways system. Inland River Services believes that approximately 30% of the dry cargo barge fleet operating on the U.S. Inland River Waterways is over 20 years old. Inland River Services expects the relatively young age of its dry cargo barge fleet to enhance its availability and reliability, reduce downtime for repairs and limit replacement capital expenditures required to maintain its fleet size and revenue generating capacity.

56

The aggregate cost of Inland River Services’ operations depends primarily on the size and mix of its fleet. Inland River Services’ operating costs and expenses are grouped into the following categories:

• barge logistics (primarily towing, switching, fleeting and cleaning costs);

• personnel (primarily wages, benefits, payroll taxes, savings plans and travel for marine personnel);

• repairs and maintenance (primarily repairs and maintenance on towboats, which are performed in accordance with planned maintenance programs);

• insurance and loss reserves (primarily the cost of Hull and Machinery, Protection and Indemnity and Cargo insurance premiums and loss deductibles);

• fuel, lubes and supplies;

• leased-in equipment (includes the cost of leasing equipment, including bought-in freight and towboats, from lessors under bareboat charter arrangements);

• other (rail car logistics, property taxes and other).

2010 compared with 2009

Operating Revenues. Operating revenues were $6.6 million higher. Operating revenues from dry cargo barge pool operations were $5.3 million higher primarily due to a larger fleet following the addition of newly constructed barges, the return of barges previously chartered-out, the addition of equipment previously included in a joint venture, and increased demurrage revenues. These increases were partially offset by a reduction in revenues from bought-in-freight activities. Operating revenues for the 10,000 barrel liquid tank barges increased by $2.5 million primarily due to equipment additions.

Costs and Expenses. Operating expenses were $7.7 million higher. Barge logistics expenses were $11.4 million higher primarily due to more activity in the dry cargo barge pool and a 22% increase in fuel prices. The cost of leased-in equipment was $6.8 million lower due to a reduction in bought-in-freight activities.

Gains on Asset Dispositions. Gains on asset dispositions were $27.2 million higher. Gains in 2010 included the sale of 60 dry cargo barges to Inland River Services’ South American joint venture and the recognition of gains previously deferred following the acquisition of a controlling interest in another of its joint ventures.

Other, net. Other, net includes the sale of the Company’s claim against the prime broker for one of its joint ventures that was impaired in 2008.

58

2009 compared with 2008

Operating Revenues. Operating revenues were $11.1 million higher. Operating revenues from dry cargo pool operations were $0.6 million lower in 2009 primarily due to reductions in grain exports, reduced demand for imported construction materials, decreased movements of other industrial cargos due to the economic recession in the United States and a reduction in available barge days due to the sale of barges to the Company’s South American joint venture. These reductions were partially offset by an increase in revenues from bought-in-freight activities. Operating revenues from the liquid unit tow operation were $8.7 million higher in 2009 primarily due to additional equipment added throughout 2008 and 2009. Operating revenues for towboat operations and other activities were $6.2 million higher primarily due to a full year of activity at the Sauget, Illinois terminal, which opened in May 2008.

Costs and Expeneses. Operating expenses were $7.0 million higher in 2009 compared with 2008. Barge logistics expenses were $13.0 million lower in line with lower activity levels for the dry cargo barge pool. Personnel costs were higher due to operating additional equipment in the liquid unit tow operation and the cost of leased-in equipment was $12.6 million higher primarily due to an increase in bought-in-freight activities.

Gains on Asset Dispositions. Gains on asset dispositions were $5.7 million lower. Gains in 2008 included the sale of 36 barges to Inland River Services’ South American joint venture.

Equity in Earnings of 50% or Less Owned Companies. Equity in earnings in 2008 include losses from the recognition of an impairment charge on prime brokerage exposure.

Marine Transportation Services

Demand for the Company’s tankers is dependent on several factors, including petroleum production and refining activity levels in the United States, domestic consumer and commercial consumption of petroleum products, and chemicals and competition from foreign imports of oil products. During 2007 and 2006, orders placed by industry participants for the construction of new double-hulled vessels qualified for operation in the U.S. coastwise trade created uncertainty as to whether the market would be able to absorb such additional capacity. In response to the uncertainty of both demand and supply factors and in order to secure a portion of the fleet’s future earnings, Marine Transportation Services entered into long-term arrangements to bareboat charter-out four vessels with staggered delivery dates. The first vessel began its charter in March 2007, the second in September 2008, the third in January 2010, and the fourth in October of 2010.

As of December 31, 2010, the Company believes third parties had contracted to build approximately eight U.S.-flag tank vessels that could compete with Marine Transportation Services’ equipment. Six vessels are scheduled to be delivered in 2011, one vessel in 2012, and the remaining vessel in 2013. It is anticipated that retirements of U.S.-flag tank vessels under OPA 90 regulations will be two in 2011, one in 2012 and another three between 2013 and January 1, 2015.

Marine Transportation Services’ operating costs and expenses are grouped into the following categories:

• personnel (primarily wages, benefits, payroll taxes, savings plans and travel for marine personnel);

• repairs and maintenance (primarily routine repairs and maintenance and overhauls which are performed in accordance with planned maintenance programs);

• drydocking (primarily the cost of regulatory drydockings performed in accordance with applicable regulations);

• insurance and loss reserves (primarily the cost of Hull and Machinery and Protection and Indemnity insurance premiums and loss deductibles);

• fuel, lubes and supplies;

• leased-in equipment (includes the cost of leasing tankers from lessors under bareboat charter arrangements);

• other (port charges, freight, vessel inspection expenses and other).

59

Vessel drydockings are regularly performed in accordance with applicable regulations and the Company expenses drydocking costs as incurred. If a disproportionate number of drydockings are undertaken in a particular fiscal year or quarter, operating expenses may vary significantly when compared with a prior year or prior quarter.

2010 compared with 2009

Operating Revenues. Time charter revenues were $8.5 million lower primarily due to changes in the contract status of two vessels from time charter to long-term bareboat charter, one effective January 21, 2010 and the other effective August 21, 2010. Bareboat charter revenues increased by $11.4 million due to the change in contract status of the two vessels to long-term bareboat charter. Contract of affreightment and other revenues were $19.6 million lower due to fewer vessels operating in the spot market, reduced spot market demand and the lay-up of the Seabulk America in August 2010.

Costs and Expenses. Operating expenses were $11.3 million lower in 2010 consistent with more vessels operating under bareboat charters and fewer vessels operating in the spot market. Drydocking expenses were $1.5 million higher in 2010 as two tankers underwent regulatory drydockings and two others underwent short handover drydockings prior to commencing long-term bareboat charters. Leased-in equipment expenses were higher in 2010 due to the sale-leaseback of two vessels under long-term bareboat charters.

Depreciation and amortization expenses were $3.4 million lower in 2010 due to the sale-leaseback of two vessels and the write down of the Seabulk America, which was reduced to fair value in the third quarter.

Gains (Losses) on Asset Dispositions and Impairments, Net. The Company believes the Seabulk America is one of six vessels designed and certified to carry complicated chemical cargos in the domestic coastwise trade. As previously reported, the Seabulk America had been scheduled to undergo a regulatory dry-docking during the third quarter of 2010, a requirement for continued operation. Given the prevailing market conditions, the Company deferred the drydocking, laid-up the vessel and recognized an impairment charge of $18.7 million reducing the vessel’s carrying value to its fair value of $5.0 million. The Seabulk America contributed operating revenues of $5.2 million from the beginning of the year through its lay-up in August 2010.

2009 compared with 2008

Operating Revenues. Operating revenues were $21.2 million lower primarily due to changes in the contract status of three vessels: one from time charter to long-term bareboat charter commencing in September 2008; a second from spot market to time charter commencing in April 2009; and a third from spot market to time charter commencing in August 2009. The third vessel was also off-hire for 28 days in 2009 while undergoing regulatory drydocking and repairs. Operating revenues for two other vessels decreased due to lower utilization, one of which was temporarily laid-up between August 2009 and the end of the year. Operating revenues were higher for two vessels that underwent regulatory drydockings in 2008.

61

Costs and Expenses. Operating expenses were $21.7 million lower in 2009 consistent with more vessels operating under bareboat charters and fewer vessels operating in the spot market. Drydocking expenses were $1.8 million lower in 2009 as one tanker underwent a regulatory drydocking compared with two in 2008.

Gains (Losses) on Asset Dispositions and Impairments, Net. The gains in 2008 resulted from the sale and subsequent scrapping of the Seabulk Power and Seabulk Magnachem.

Environmental Services

Environmental Services charges fees for its consulting and industrial and remediation services on both a time and material basis and on a fixed fee bid basis. In both cases the total fees charged are dependent upon the scope of work to be accomplished and the labor and equipment required to carry it out. The margins on time and material services are more predictable and for the most part are larger than for fixed fee work. The margins on equipment-intensive jobs are normally higher than labor-intensive jobs.

Operating results and cash flows can be very dependent on the number of emergency responses in a given fiscal period, the magnitude of each emergency and the profit margin earned. Consequently, emergency response revenues and related income can vary materially between comparable periods. The revenues from any one period are not indicative of a trend or anticipated results in future periods. Environmental Services’ 2010 operating results were significantly impacted by its involvement in the Oil Spill Response.

Costs of emergency response activities can include payments to sub-contractors for labor, equipment and materials and/or the direct charge of labor, equipment and materials provided by Environmental Services. Profit margins vary based on the use of the Company’s personnel and equipment resources versus the use of third-party personnel and equipment.

The principal components of Environmental Services’ operating expenses are salaries and related benefits for operating personnel, payments to subcontractors, equipment maintenance and depreciation. These expenses are primarily a function of regulatory requirements and the level of retainer, spill, consulting and other environmental business activities.

2010 compared with 2009

Operating Revenues. Operating revenues increased by $728.6 million due to increased emergency response and project management revenues related to the Oil Spill Response. Emergency response activities accounted for 84% and 28% of Environmental Services’ operating revenues in 2010 and 2009, respectively.

Costs and Expenses. Operating expenses increased by $489.5 million. Increased subcontractor and personnel costs of $481.6 million and $8.1 million, respectively, were due to additional personnel employed as well as additional resources required from third parties as a result of the Oil Spill Response.

General and administrative expenses were $6.1 million higher in 2010 primarily due to higher wages and compensation expense.

2009 compared with 2008

Operating Revenues. Operating revenues decreased by $22.3 million primarily due to lower project management, emergency response and professional service revenue partially offset by higher retainer service revenue. The decrease in project management services was primarily due to the impact of higher operating revenues contributed from pipeline repair projects in the Republic of Georgia and Turkey and from industrial services activity primarily on the U.S. West Coast in 2008. The decrease in emergency response revenues was primarily due to higher activity in 2008 relating to Hurricane Gustav. Operating revenues from consulting services were lower in 2009 primarily due to a decrease in platform recovery, planning and public assistance recovery services. The increase in retainer services was primarily due higher retainer from ship owners due to greater vessel activity and higher fees. Emergency response activities accounted for 28% and 26% of Environmental Services’ operating revenues in 2009 and 2008, respectively.

Costs and Expenses. Operating expenses decreased by $13.6 million. The decrease was primarily due to higher subcontractor and personnel costs related to pipeline repair projects in the Republic of Georgia and Turkey in 2008.

General and administrative expenses were $2.1 million lower in 2009 primarily due to lower wage and benefit costs.

Commodity Trading and Logistics

The profitability of Commodity Trading and Logistics is affected by the availability and market prices of agricultural and energy commodities and the availability and costs of transportation and logistics services, including truck, barge, rail and ocean freight.

Commodity Trading and Logistics expects that population growth, rising standards of living and rising global demand for renewable fuels will continue to increase global demand for agricultural and energy commodities. However, from time to time, imbalances may exist between capacity and demand for rice, sugar and energy-related products in certain markets, which impacts whether, when and where to purchase, store, transport or sell these commodities.

⁽¹⁾ In the Company’s energy and sugar trading businesses, fixed price future purchase and sale contracts for ethanol and sugar are included in derivative positions at fair value. The Company routinely enters into exchange traded positions to offset its net commodity market exposure on these purchase and sale contracts as well as its inventory balances. As a result, derivative gains (losses), net recognized during any period are predominately offset by fair value adjustments included in operating revenues and expenses on completed transactions, subject to certain timing differences on the delivery of physical inventories. As of December 31, 2010 and 2009, the net market exposure to ethanol and sugar under its contracts and inventory balances was not material.

2010 compared with 2009

Energy. Operating revenues and operating expenses were significantly higher in 2010 reflecting increased activity in renewable fuel and clean blendstock trading, including logistics and transport, and hydrocarbon transportation revenues. Segment profit declined primarily due to lower margins on activities, the recognition of derivative losses on hedging physical inventory positions and start-up costs associated with the Company’s alcohol manufacturing joint venture.

Sugar. Segment results in 2010 improved primarily due to the recognition of a $1.5 million bad debt provision in 2009.

Rice. Segment losses from rice activities in 2010 were primarily due to costs incurred during the winding down of rice trading activities and market write-downs of rice inventories. As previously reported, the Company has decided to reduce its rice activities and has substantially liquidated its rice inventories.

2009 compared with 2008

Segment Profit (Loss). Segment results declined primarily due to the decline in margin on rice sales and higher provisions for doubtful accounts, partially offset by improved results from ethanol activities.

Harbor and Offshore Towing Services. Segment profit increased in 2010 compared with 2009 primarily due to activity associated with the Oil Spill Response. These increases were partially offset by higher repair and fuel costs and higher expenses related to insurable incidents. Segment profit decreased in 2009 compared with 2008 primarily due to the conclusion of several long-term outside harbor contracts and lower harbor tug activity as a result of reductions in shipping activities in the ports in which Harbor and Offshore Towing Services operates.

Other, net. Segment loss in 2010 resulted primarily from expenditures for business development.

Corporate Expenses. Corporate expenses in 2010 were higher primarily due to higher management bonus accruals, the acceleration of restricted stock awards into 2010 that were scheduled to lapse in 2011, and amounts designated for a foundation that will provide financial support to selected charities and projects in various parts of the Southeastern United States affected by the Deepwater Horizon oil spill.

Derivative gains (losses), net. Derivative gains, net in 2010 were primarily due to gains on U.S. Treasury note, rate lock and bond future and option contracts of $8.5 million, forward currency exchange option and future contracts of $3.9 million and equity options of $2.1 million partially offset by losses on interest rate swaps of $3.5 million. Derivative gains, net in 2009 were primarily due to gains on forward currency exchange option and future contracts of $2.3 million and equity options of $3.1 million. Derivative losses, net in 2008 were primarily due to losses on U.S. treasury note, rate lock and bond future and option contracts of $7.7 million and forward currency exchange, option and future contracts of $15.3 million partially offset by gains on equity options of $9.6 million.

Foreign currency gains (losses), net. Foreign currency losses, net in 2010 were primarily due to a strengthening of the U.S. dollar against foreign currencies underlying certain of the Company’s intercompany notes receivable and cash balances.

Liquidity and Capital Resources

Overview

The Company’s ongoing liquidity requirements arise primarily from working capital needs, meeting its capital commitments and the repayment of debt obligations. In addition, the Company may use its liquidity to fund acquisitions, repurchase shares of SEACOR common stock, par value $0.01 per share (“Common Stock”), for treasury or to make other investments. Sources of liquidity are cash balances, marketable securities, construction reserve funds, Title XI reserve funds, cash flows from operations and borrowings under the Company’s revolving credit facility. From time to time, the Company may secure additional liquidity through the issuance of debt, shares of Common Stock, preferred stock or a combination thereof.

68

The Company’s unfunded capital commitments as of December 31, 2010 consisted primarily of offshore support vessels, helicopters, an interest in a dry-bulk articulated tug-barge and other equipment. These commitments totaled $254.3 million, of which $169.9 million is payable during 2011 with the balance payable through 2013. Subsequent to December 31, 2010, the Company committed to purchase additional equipment of $10.8 million.

As of December 31, 2010, construction reserve funds of $314.3 million were classified as non-current assets in the accompanying condensed consolidated balance sheets as the Company has the intent and ability to use the funds to acquire equipment.

SEACOR’s Board of Directors previously approved a securities repurchase plan that authorizes the Company to acquire Common Stock, which may be acquired through open market purchases, privately negotiated transactions or otherwise, depending on market conditions. On February 18, 2010, SEACOR’s Board of Directors increased the repurchase authority up to $250.0 million and, as of December 31, 2010, the remaining authority under the repurchase plan was $113.0 million.

As of December 31, 2010, the Company had $125.0 million of outstanding borrowings under its revolving credit facility. The remaining availability under this facility as of December 31, 2010 was $323.5 million, net of issued letters of credit of $1.5 million.

Short and Long-Term Liquidity Requirements

Current economic conditions have continued to disrupt the credit markets. To date, the Company’s liquidity has not been materially impacted by the current credit environment and management does not expect that it will be materially impacted in the near-future. The Company anticipates it will continue to generate positive cash flows from operations and that these cash flows will be adequate to meet the Company’s working capital requirements. In support of the Company’s capital expenditure program and/or other liquidity requirements, the Company may use cash balances, sell securities, utilize construction reserve funds, sell additional vessels or other equipment, enter into sale and leaseback transactions for equipment, borrow under its revolving credit facility, issue debt or a combination thereof.

The Company’s long-term liquidity is dependent upon its ability to generate operating profits sufficient to meet its requirements for working capital, capital expenditures and a reasonable return on shareholders’ investment. The Company believes that earning such operating profits will permit it to maintain its access to favorably priced debt, equity or off-balance sheet financing arrangements. Management will continue to closely monitor the Company’s liquidity and the credit markets.

Off-Balance Sheet Arrangements

On occasion, the Company and its partners will guarantee certain obligations on behalf of their joint ventures. As of December 31, 2010, the Company had the following guarantees in place:

• The Company is a guarantor of 50% of the outstanding debt for one of its domestic offshore marine joint ventures. The amount guaranteed by the Company declines as principal payments are made and

73

will terminate when the debt is repaid. The debt matures in 2015. As of December 31, 2010, the amount of the Company’s guarantee was $13.6 million.

• The Company is a party to two international offshore marine joint ventures which obtained bank debt to finance the acquisition of offshore support vessels from the Company. The debt is secured by, among other things, a first preferred mortgage on the vessels. The bank also has the authority to require the parties to the joint ventures to fund the uncalled capital commitments, as defined in the joint ventures’ partnership agreements. In such event, the Company would be required to contribute its allocable share of uncalled capital, which was $2.5 million, in the aggregate, as of December 31, 2010. The Company manages these vessels on behalf of the joint ventures and guarantees the outstanding charter receivables of one of the joint ventures if a customer defaults in payment and the Company either fails to take enforcement action against the defaulting customer or fails to assign its right of recovery against the defaulting customer. As of December 31, 2010, the Company’s contingent guarantee of the joint venture’s outstanding charter receivables was $1.6 million.

• The Company guaranteed up to $0.9 million with respect to amounts owing pursuant to a vessel charter agreement between one of the Company’s domestic offshore marine joint ventures and the owner of the chartered vessel. The amount of the Company’s guarantee declines over the life of the charter and terminates in 2011.

• The Company guaranteed up to $0.4 million as security for the performance of a contract between an Environmental Services’ joint venture and a customer in Turkey.

• The Company is guarantor of 50% of the outstanding debt for a joint venture that owns two offshore high speed catamaran crew boats. The amount of the guarantees decline as principal payments are made and will terminate when the debt is schedule to be repaid. The debt matures in 2015. As of December 31, 2010, the amount of the Company’s guarantee was $10.5 million.

Effects of Inflation

The Company’s operations expose it to the effects of inflation. In the event that inflation becomes a significant factor in the world economy, inflationary pressures could result in increased operating and financing costs.

Contingencies

During 2006 and 2007, Marine Transportation Services (“MTS”) had two of its tankers retrofitted to a double-hull configuration in a foreign shipyard to enable each of them to continue to transport crude oil and petroleum products beyond their OPA 90 mandated retirement dates in 2011. Both vessels operate in the U.S. coastwise trade that, under the Shipping Acts, is restricted to vessels built or rebuilt in the United States. In May 2005, MTS received a determination from the U.S. Coast Guard (“USCG”), which administers the United States build requirements of the Shipping Acts, concluding the retrofit work would not constitute a foreign rebuilding and therefore would not jeopardize the tankers’ eligibility to operate in the U.S. coastwise trade. MTS completed the retrofit work in the foreign shipyard in reliance upon the USCG’s determination, which MTS believes was correct and in accord with the USCG’s long-standing regulations and interpretations. On July 9, 2007, a U.S. shipbuilders trade association and two operators of tankers in the U.S. coastwise trade (“Shipbuilders”) commenced a civil action in the U.S. District Court for the Eastern District of Virginia, Shipbuilders Council of America, Inc., et al. v. U.S. Department of Homeland Security, et al., No. 1:07cv665 (E.D. Va.) (the “SB Trader Litigation”), in which they sought to have the court set aside the USCG’s determination and direct the USCG to revoke the coastwise license of one of the two retrofitted tankers, the Seabulk Trader. MTS intervened in the action to assist the USCG in defending its determination. On April 24, 2008, the Court issued a Memorandum Opinion granting a motion for summary judgment by Shipbuilders setting aside the USCG’s determination and remanding the matter to the USCG for further proceedings with instructions to revoke the coastwise endorsement of the Seabulk Trader. On April 30, 2008, MTS appealed the decision to the U.S. Court of Appeals for the Fourth Circuit (the “Court of Appeals”), and the lower court’s decision was stayed pending appeal, subject to certain terms (which MTS also separately appealed). Those terms required that MTS pay to the plaintiffs 12.5% of the revenue generated by the Seabulk Trader from November 7, 2008 in the event that the Court of Appeals affirms the lower court’s decision to revoke its coastwise endorsement (the “Undertaking”). On July 2, 2008, Shipbuilders commenced a second civil action in the U.S. District Court for the Eastern District of Virginia, entitled Shipbuilders Council of America, Inc., et al. v. U.S. Department of Homeland Security, et al., No. 1:08cv680 (E.D. Va.) (the “SB Challenge Litigation”), alleging essentially identical claims as those asserted in the SB Trader Litigation against MTS’s second retrofitted tanker, the Seabulk Challenge. MTS has intervened in the SB Challenge Litigation that was stayed pending the decision of the Court of Appeals in the SB Trader Litigation. In September 2009, the Court of Appeals reversed the District Court, holding that the USCG’s interpretation was correct and that the District Court erred in requiring MTS to provide the Undertaking. On January 19, 2010, the District Court vacated its April 24, 2008 Order to the extent it directed the USCG to revoke the coastwise endorsement for the Seabulk Trader and remanded the matter to the USCG with instructions to (i) provide a fuller explanation of one aspect of its rebuild decision and (ii) consider further whether certain work relating to the vessel’s segregated ballast tanks constituted a prohibited foreign installation of required segregated

75

ballast tanks. On August 31, 2010, the USCG issued a further determination further explaining its rebuild decision and concluding that the work relating to the vessel’s segregated ballast tanks did not constitute the installation of a required segregated ballast tank. One of the three plaintiffs in the District Court litigation urged the USCG to reach a contrary result with respect to the segregated ballast work, and it is possible that the plaintiff will ask the District Court to set aside this aspect of the USCG’s decision as well. The loss of coastwise eligibility for its two retrofitted tankers could lead to impairment concerns and could adversely affect the Company’s financial condition and its results of operations. The aggregate carrying value of the Company’s two retrofitted tankers was $46.0 million as of December 31, 2010 and such tankers contributed operating revenues of $19.8 million during the year ended December 31, 2010.

Certain subsidiaries of the Company are participating employers in an industry-wide, multi-employer, defined benefit pension fund, the United Kingdom Merchant Navy Officers Pension Fund (“MNOPF”). Under the direction of a court order, any deficit of the MNOPF is to be remedied through funding contributions from all participating employers. The Company’s participation relates to officers employed between 1978 and 2002 by SEACOR’s Stirling group of companies (which had been acquired by SEACOR in 2001) and its predecessors. Based on an actuarial valuation of the MNOPF in 2003, the Company was invoiced and expensed $4.4 million in 2005, representing the Company’s allocated share of a total funding deficit of $412.0 million. Subsequent to this invoice, the pension fund trustees determined that $49.0 million of the $412.0 million deficit was deemed uncollectible due to the non-existence or liquidation of certain participating employers and the Company was invoiced and expensed $0.6 million in 2007 for its allocated share of the uncollectible deficit. Based on an actuarial valuation of the MNOPF in 2006, the Company was invoiced and expensed $3.9 million in 2007, representing the Company’s allocated share of an additional funding deficit of $332.6 million. Based on an actuarial valuation of the MNOPF in 2009, the Company was invoiced and expensed $7.8 million in 2010, representing the Company’s allocated share of an additional funding deficit of $636.9 million. Depending on the results of future actuarial valuations, it is possible that the MNOPF will experience further funding deficits, requiring the Company to recognize payroll related operating expenses in the periods invoices are received.

A subsidiary of the Company is a participating employer in an industry-wide, multi-employer, defined benefit pension fund, the United Kingdom Merchant Navy Ratings Pension Fund (“MNRPF”). The Company’s participation relates to ratings employed between 1978 and 2001 by SEACOR’s Stirling group of companies (which had been acquired by SEACOR in 2001) and its predecessors. Based on an actuarial valuation in March 2008, the MNRPF has an accumulated funding deficit of $320.9 million (£203.0 million). No decision has yet been reached as to how the deficit will be recovered, but the Company expects it is likely that participating employers will be invoiced for their allocated share, at which time the Company would recognize payroll related operating expenses. The Company estimates its allocated share of the uninvoiced deficit to be approximately $1.1 million (£0.7 million). Depending on the results of the most recent and future actuarial valuations, it is possible that the MNRPF will experience further funding deficits, requiring the Company to recognize payroll related operating expenses in the periods invoices are received.

On June 12, 2009, a purported civil class action was filed against SEACOR, Era Group Inc., Era Aviation, Inc., Era Helicopters LLC and two other defendants (collectively the “Defendants”) in the U.S. District Court for the District of Delaware, Superior Offshore International, Inc. v. Bristow Group Inc., et al., No. 09-CV-438 (D.Del.). SEACOR acquired Era Group Inc., Era Aviation, Inc., and Era Helicopters LLC in December 2004. The complaint alleges that the Defendants violated federal antitrust laws by conspiring with each other to raise, fix, maintain or stabilize prices for offshore helicopter services in the U.S. Gulf of Mexico during the period January 2001 to December 2005. The purported class of plaintiffs includes all direct purchasers of such services and the relief sought includes compensatory damages and treble damages. On September 14, 2010, the District Court entered an order dismissing the complaint. On November 30, 2010, the District Court granted the plaintiffs motion for reconsideration and amendment (the “Motions”), and ordered limited discovery strictly in regard to the allegations set forth on the plaintiff’s amended complaint. The limited discovery was completed and the defendants have filed a motion for summary judgment, which is pending. The Company is unable to estimate the potential exposure, if any, resulting from these claims but believes they are without merit and intends to vigorously defend the action.

On July 14, 2010, a group of individuals and entities purporting to represent a class commenced a civil action in the U.S. District Court for the Eastern District of Louisiana, Terry G. Robin, et al. v. Seacor Marine, L.L.C., et al., No. 2:10-cv-01986 (E.D. La.), in which they assert that support vessels, including vessels owned by the Company, responding to the explosion and resulting fire that occurred aboard the semi-submersible drilling rig, the Deepwater Horizon, were negligent in their efforts to save lives and put out the fire and contributed to the sinking of the Deepwater Horizon and subsequent oil spill. The action now is part of the overall multi-district litigation, In re Oil Spill by the Oil Rig “Deepwater Horizon”, MDL No. 2179. The complaint seeks compensatory, punitive, exemplary, and other damages. The Company believes that this lawsuit brought by class action lawyers targeting emergency responders acting under the direction of the U.S. Coast Guard has no merit and will seek its dismissal. The Company also recently filed petitions seeking exoneration from or limitation of liability in relation to any actions that may have been taken by vessels owned by the Company to extinguish the fire. Pursuant to the Limitation of Liability Act, those petitions impose an automatic stay on the Robin case, and the court has set a deadline of April 20, 2011 for individual claimants to assert claims in the limitation cases.

On July 20, 2010, two individuals purporting to represent a class commenced a civil action in the Civil District Court for the Parish of Orleans in the State of Louisiana, John Wunstell, Jr. and Kelly Blanchard v. BP, et al., No. 2010-7437 (Division K) (the “Wunstell Action”), in which they assert, among other theories, that Mr. Wunstell suffered injuries as a result of his exposure to certain noxious fumes and chemicals in connection with the provision of remediation, containment and response services by O’Brien’s Response Management Inc. (“O’Brien’s), a subsidiary of SEACOR. The action now is part of the overall multi-district litigation, In re Oil Spill by the Oil Rig “Deepwater Horizon”, MDL No. 2179. The complaint also seeks to establish a “class-wide court-supervised medical monitoring program” for all individuals “participating in BP’s Deepwater Horizon Vessels of Opportunity Program and/or Horizon Response Program” who allegedly experience injuries similar to Mr. Wunstell. The Company believes this lawsuit has no merit and will seek its dismissal. Pursuant to contractual agreements with the responsible party, the responsible party has agreed, subject to certain potential limitations, to indemnify and defend O’Brien’s in connection with the Wunstell Action and claims asserted in the MDL.

On December 15, 2010, SEACOR subsidiaries O’Brien’s and National Response Corporation (“NRC”) were named as defendants in one of the several consolidated “master complaints” that have been filed in the overall multi-district litigation, In re Oil Spill by the Oil Rig “Deepwater Horizon”, MDL No. 2179. The master complaint naming O’Brien’s and NRC asserts various claims on behalf of a punitive class against multiple defendants concerning the clean-up activities generally, and the use of dispersants specifically. By court order the Wunstell Action has been stayed as a result of the filing of the referenced master complaint. The Company believes that the claims asserted against its subsidiaries in the master complaint have no merit and will seek dismissal of the master complaint against both O’Brien’s and NRC. In addition to the indemnity provided to O’Brien’s, the Company has also sought indemnity from the responsible party pursuant to certain contractual arrangements for the claims asserted against NRC in the MDL.

In the normal course of its business, the Company becomes involved in various other litigation matters including, among other things, claims by third parties for alleged property damages and personal injuries. Management has used estimates in determining the Company’s potential exposure to these matters and has recorded reserves in its financial statements related thereto as appropriate. It is possible that a change in the Company’s estimates related to these exposures could occur, but the Company does not expect such changes in estimated costs would have a material effect on the Company’s consolidated financial position or its results of operations.

During the year ended December 31, 2010, the Company received notice from the Internal Revenue Service of $12.6 million in proposed penalties regarding Marine Transportation Services’ informational excise tax filings for prior years. The Company intends to vigorously defend its position that the proposed penalties are erroneous and believes the resolution of this matter will not have a material effect on the Company’s consolidated financial position or its results of operations.

Related Party Transactions

The Company manages barge pools as part of its Inland River Services segment. Pursuant to the pooling agreements, operating revenues and expenses of participating barges are combined and the net results are allocated on a pro-rata basis based on the number of barge days contributed by each participant. Mr. Charles Fabrikant, the Executive Chairman of SEACOR, companies controlled by Mr. Fabrikant and trusts for the benefit of Mr. Fabrikant’s two children, own barges that participate in the barge pools managed by the Company. Mr. Fabrikant and his affiliates were participants in the barge pools prior to the acquisition of SCF Marine Inc. by SEACOR in 2000. In the years ended December 31, 2010, 2009 and 2008, Mr. Fabrikant and his affiliates earned $1.1 million, $1.0 million and $1.7 million, respectively, of net barge pool results (after payment of $0.1 million, $0.1 million and $0.1 million, respectively, in management fees to the Company). As of December 31, 2010, 2009 and 2008, the Company owed Mr. Fabrikant and his affiliates $0.5 million, $0.4 million and $0.7 million, respectively, for undistributed net barge pool results. Mr. Fabrikant and his affiliates participate in the barge pools on the same terms and conditions as other pool participants who are unrelated to the Company.

During the year ended December 31, 2008, the Company purchased a barge from Mr. Fabrikant’s sister for $0.5 million and sold it to Inland River Services’ South American joint venture. The proceeds received by Mr. Fabrikant’s sister were deposited into a construction reserve fund established by her that is managed by the Company. During the year ended December 31, 2008, the Company, on behalf of Mr. Fabrikant, sold three barges owned by him for scrap, for $0.3 million.

Mr. Fabrikant is also a director of Diamond Offshore Drilling, Inc. (“Diamond”), which is also a customer of the Company. The total amount earned from business conducted with Diamond did not exceed $5.0 million in any of the years ended December 31, 2010, 2009 or 2008.

Critical Accounting Policies and Estimates

General. 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates include those related to deferred revenues, allowance for doubtful accounts, useful lives of property and equipment, impairments, income tax provisions and certain accrued liabilities. Actual results could differ from those estimates and those differences may be material.

Revenue Recognition. The Company recognizes revenue when it is realized or realizable and earned. Revenue is realized or realizable and earned when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price to the buyer is fixed or determinable, and collectability is reasonably assured. Revenue that does not meet this criteria is deferred until the criteria are met.

The Company’s Offshore Marine Services segment earns and recognizes revenues primarily from the time charter and bareboat charter of vessels to customers based upon daily rates of hire. Under a time charter, Offshore Marine Services provides a vessel to a customer and is responsible for all operating expenses, typically excluding fuel. Under a bareboat charter, Offshore Marine Services provides the vessel to the customer and the customer assumes responsibility for all operating expenses and risk of operation. Vessel charters may range from several days to several years. Revenues from time charters and bareboat charters are recorded and recognized as services are provided. In the U.S. Gulf of Mexico, time charter durations and rates are typically established in the context of master service agreements, which govern the terms and conditions of charter.

The Company’s Aviation Services segment charters its helicopters to utility and oil and gas customers primarily through master service agreements, term contracts, day-to-day charter arrangements and leases. Master service agreements require incremental payments above a fixed rental fee based upon flight hours flown, have

78

fixed terms ranging from one month to five years and generally are cancelable upon 30 days notice. Term contracts and day-to-day charter arrangements are generally non-cancelable without cause and call for a combination of a monthly or daily fixed rental fee plus a charge based on hours flown. Day-to-day charter arrangements are generally based on either an hourly or daily rate. Leases can be either dry, providing only the equipment, or wet, providing equipment, insurance and personnel. Fixed rental fee revenues are recognized ratably over the contract term. Usage or hourly based revenues are recognized as hours are flown. Aviation Services’ air medical activities are provided under contracts with hospitals that typically include either a fixed monthly and hourly rate structure or a fee per completed flight. Fixed monthly revenues are recognized ratably over the month while per hour or per flight based revenues are recognized as hours are flown or flights are completed. The Company’s air medical activities are provided under contracts with hospitals that typically include either a fixed monthly and hourly rate structure, similar to oil and gas, or a fee per completed flight. Fixed monthly revenues are recognized ratable over the month while per hour or per flight based revenues are recognized as hours are flown or flights are completed. Most contracts with hospitals are longer term, but offer either party the ability to terminate with less than six months notice. The Company operates some air medical contracts pursuant to which it collects a fee per flight, either from a hospital or insurance company. With respect to flightseeing activities, Aviation Services allocates block space to cruise lines and sells seats directly to customers with revenues for helicopter usage recognized as the services are performed.

The Company’s Inland River Services segment earns revenues primarily from voyage affreightment contracts whereby customers are charged an established rate per ton to transport cargo from point to point. Revenues from voyage affreightment contracts are generally recognized over the progress of the voyage while the related costs are expensed as incurred. Certain of Inland River Services’ barges are operated in barge pools with other barges owned by third parties from whom Inland River Services earns and recognizes a management fee as the services are rendered. Pursuant to the pooling agreements, operating revenues and expenses of participating barges are combined and the net results are allocated on a pro-rata basis based on the number of barge days contributed by each participant. In addition, revenues are earned from equipment chartered to third parties and from the storage and demurrage of cargos associated with affreightment activities. In both of these cases, revenues are recognized as services are rendered. Inland River Services’ tank farm and handling facility earns revenues through rental and throughput charges. Rental revenues are recognized ratably over the rental period while throughput charges are recognized as product volume moves through the facility.

The Company’s Marine Transportation Services segment earns revenue from the time charter, bareboat charter and voyage charter of vessels and under contracts of affreightment. Under a time charter, Marine Transportation Services provides a vessel to a customer and is responsible for all operating expenses, typically excluding fuel. Under a bareboat charter, Marine Transportation Services provides the vessel to a customer and the customer assumes responsibility for all operating expenses and risk of operation. Revenues from time charters and bareboat charters are recognized as services are provided. Voyage contracts are contracts to carry cargos on a single voyage basis regardless of time to complete. Contracts of affreightment are contracts for cargos that are committed on a multi-voyage basis for various periods of time with minimum and maximum cargo tonnages specified over the period at a fixed or escalating rate per ton. Revenues for voyage contracts and contracts of affreightment are recognized over the progress of the voyage while the related costs are expensed as incurred.

The Company’s Environmental Services segment earns revenues primarily from emergency response, retainer, consulting and training, project management and remediation services. Emergency response revenues are recognized as services are provided and are dependent on the magnitude and number of individual responses. Retainer agreements with vessel owners generally range from one to three years while retainer agreements with facility owners can be as long as ten years. Such retainer fees are generally recognized ratably over the term of the contract. Consulting and training services fees are recognized as the services are provided based on the contract terms. Project management and remediation services are provided on a time and material basis with revenues recognized as the services are provided or on a fixed fee bid basis with revenues and expenses recognized upon completion of the contract.

79

The Company’s Commodity Trading and Logistics segment earns revenues from the sale of rice, sugar and renewable fuels (primarily ethanol), the rental of tank storage, and through voyage affreightment contracts on leased-in liquid tank barges and towboats. Revenues from rice, sugar and renewable fuel sales are recorded when title transfers to the buyer, typically when cash is received. Revenues from the rental of tank storage are recognized ratably over the lease periods. Revenues from voyage affreightment contracts are generally recognized over the progress of the voyage while the related costs are expensed as incurred.

Trade Receivables. Customers of Offshore Marine Services, Aviation Services and Marine Transportation Services are primarily major and independent oil and gas exploration and production companies. Customers of Inland River Services are primarily major agricultural and industrial companies based within the United States. Oil spill, emergency response and remediation services are provided by Environmental Services to domestic and international shippers, major oil companies, independent exploration and production companies, pipeline and transportation companies, power generating operators, industrial companies, airports and state and local government agencies. Customers of Commodity Trading and Logistics include major agricultural and industrial companies, major and independent oil and gas production companies, foreign governments and local distributors. All customers are granted credit on a short-term basis and related credit risks are considered minimal. The Company routinely reviews its trade receivables and makes provisions for probable doubtful accounts; however, those provisions are estimates and actual results could differ from those estimates and those differences may be material. Trade receivables are deemed uncollectible and removed from accounts receivable and the allowance for doubtful accounts when collection efforts have been exhausted.

Derivative Instruments. The Company accounts for derivatives through the use of a fair value concept whereby all of the Company’s derivative positions are stated at fair value in the accompanying consolidated balance sheets. Realized and unrealized gains and losses on derivatives not designated as hedges are reported in the accompanying consolidated statements of income as derivative gains (losses), net. Realized and unrealized gains and losses on derivatives designated as fair value hedges are recognized as corresponding increases or decreases in the fair value of the underlying hedged item to the extent they are effective, with any ineffective portion reported in the accompanying consolidated statements of income as derivative gains (losses), net. Realized and unrealized gains and losses on derivatives designated as cash flow hedges are reported as a component of other comprehensive income in the accompanying consolidated statement of changes in equity to the extent they are effective and reclassified into earnings on the same line item associated with the hedged transaction and in the same period the hedged transaction affects earnings. Any ineffective portion of cash flow hedges are reported in the accompanying consolidated statements of income as derivative gains (losses), net. Realized and unrealized gains and losses on derivatives designated as cash flow hedges that are entered into by the Company’s equity method investees are also reported as a component of the Company’s other comprehensive income (loss) in proportion to the Company’s ownership percentage in the investee, with reclassifications and ineffective portions being included in equity in earnings of 50% or less owned companies, net of tax, in the accompanying consolidated statements of income.

Inventories. Inventories are stated at the lower of cost (using the first-in, first-out method) or market. Inventories consist primarily of fuel and fuel oil in the Company’s Offshore Marine Services, Marine Transportation Services and Inland River Services segments, spare parts and fuel in the Company’s Aviation Services segment, and ethanol and rice in the Company’s Commodity Trading and Logistics segment. The Company records write-downs, as needed, to adjust the carrying amount of inventories to the lower of cost or market.

Property and Equipment. Equipment, stated at cost, is depreciated using the straight line method over the estimated useful life of the asset to an estimated salvage value. With respect to each class of asset, the estimated useful life is typically based upon a newly built asset being placed into service and represents the point at which it is typically not justifiable for the Company to continue to operate the asset in the same or similar manner. From time to time, the Company may acquire older assets that have already exceeded the Company’s useful life policy, in which case the Company depreciates such assets based on its best estimate of remaining useful life, typically the next survey or certification date.

80

As of December 31, 2010, the estimated useful life (in years) of each of the Company’s major classes of new equipment was as follows:

Offshore support vessels	20
Helicopters	12
Inland river dry cargo and deck barges	20
Inland river liquid tank barges	25
Inland river towboats	25
U.S.-flag tankers(1)	25
Harbor and offshore tugs(2)	25
Ocean liquid tank barges	25

⁽¹⁾ Subject to Oil Pollution Act of 1990 (“OPA 90”) requirements.

⁽²⁾ Effective April 1, 2008, the Company changed its estimated useful life for newly built harbor and offshore tugs from 40 to 25 years and reduced the remaining useful life of certain vessels within its harbor and offshore tug fleet due to the more frequent occurrence of technological advancements in vessel design. These changes in estimates did not materially impact the comparability of financial information for the periods presented.

Equipment maintenance and repair costs and the costs of routine overhauls, drydockings and inspections performed on vessels and equipment are charged to operating expense as incurred. Expenditures that extend the useful life or improve the marketing and commercial characteristics of equipment as well as major renewals and improvements to other properties are capitalized. Certain third party vendors maintain helicopter components and engines on some of the Company’s helicopters under programs that require the Company to pay ratably for the service based on flight hours flown. These costs are normally billed monthly and expensed as incurred. In the event the Company places a helicopter in a program after a maintenance period has begun, it may be necessary to pay an initial buy-in charge based on hours flown to date with such charge being amortized over the contract period. If a helicopter is sold before the scheduled maintenance work is carried out, the Company may be able to recover part of the expenditure incurred up to that point. The impact of the entry into and exit from these programs could have a significant impact on the Company’s repair and maintenance costs.

Impairment of Long-Lived Assets. The Company performs an impairment analysis of long-lived assets used in operations, including intangible assets, when indicators of impairment are present. If the carrying value of the assets is not recoverable, as determined by the estimated undiscounted cash flows, the carrying value of the assets is reduced to fair value. Generally, fair value is determined using valuation techniques, such as expected discounted cash flows or appraisals, as appropriate.

Impairment of 50% or Less Owned Companies. The Company performs regular reviews of each investee’s financial condition, the business outlook for its products and services, and its present and projected results and cash flows. When an investee has experienced consistent declines in financial performance or difficulties in raising capital to continue operations, and when the Company expects the decline to be other-than-temporary, the investment is written down to fair value. Actual results may vary from estimates due to the uncertainty regarding the projected financial performance of investees, the severity and expected duration of declines in value, and the available liquidity in the capital markets to support the continuing operations of the investees in which the Company has investments.

Goodwill. Goodwill is recorded when the purchase price paid for an acquisition exceeds the fair value of net identified tangible and intangible assets acquired. The Company performs an annual impairment test of goodwill and further periodic tests to the extent indicators of impairment develop between annual impairment tests. The Company’s impairment review process compares the fair value of the reporting unit to its carrying value, including the goodwill related to the reporting unit. To determine the fair value of the reporting unit, the Company uses a discounted future cash flow approach that uses estimates for revenues, costs and appropriate

81

discount rates, among others. These estimates are reviewed each time the Company tests goodwill for impairment and are typically developed as part of the Company’s routine business planning and forecasting process. While the Company believes its estimates and assumptions are reasonable, variations from those estimates could produce materially different results.

Income Taxes. Deferred income tax assets and liabilities have been provided in recognition of the income tax effect attributable to the book and tax basis differences of assets and liabilities reported in the accompanying consolidated financial statements. Deferred tax assets or liabilities are provided using the enacted tax rates expected to apply to taxable income in the periods in which they are expected to be settled or realized. Interest and penalties relating to uncertain tax positions are recognized in interest expense and administrative and general, respectively, in the accompanying consolidated statements of income. The Company records a valuation allowance to reduce its deferred tax assets if it is more likely than not that some portion or all of the deferred tax assets will not be realized.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

The Company has foreign currency exchange risks primarily related to its vessel operations that are conducted from ports located in the United Kingdom where its functional currency is the pound sterling. Net consolidated assets of £20.2 million ($31.2 million) are included in the Company’s consolidated balance sheets as of December 31, 2010. A 10% weakening in the exchange rate of the pound sterling against the U.S. dollar as of December 31, 2010, would increase other comprehensive loss by $2.0 million, net of tax, due to translation. In addition, SEACOR provided a $15.3 million (£9.9 million) U.S. dollar denominated loan to a United Kingdom subsidiary. A 10% weakening in the exchange rate of the pound sterling against the U.S. dollar as of December 31, 2010, would result in foreign currency losses of $1.0 million, net of tax.

As of December 31, 2010, the Company held marketable securities with a fair value of $147.4 million, including $94.7 million in fixed income investments consisting of corporate debt securities, municipal bonds, and foreign government bonds, and $52.7 million in equity securities. As of December 31, 2009, the Company held marketable securities with a fair value of $68.1 million, including $48.0 million in fixed income investments consisting of corporate debt securities, municipal bonds, and foreign government bonds, and $20.1 million in equity securities. From time to time, the Company may increase its level of investment in fixed income securities including U.S. government bonds, foreign government bonds, state and municipal bonds, and corporate notes with maturities ranging from a few months to many years. The fair value of such investments fluctuates based on market interest rates and the creditworthiness of the issuers of the securities. When making substantial investments in fixed income securities, the Company manages its risk associated with these investments by analyzing the creditworthiness of issuers and utilizing other techniques that may include maintaining a ladder of maturities. The Company’s investment in equity securities primarily includes positions in energy, marine, transportation and other related businesses. As of December 31, 2010, a 10% decline in the value of the Company’s investments in marketable securities would reduce income by $9.6 million, net of tax.

The Company held positions in short sales of marketable equity securities with a fair value of $36.1 million and $18.4 million as of December 31, 2010 and 2009, respectively. The Company’s short sales of marketable equity securities primarily include positions in energy, marine, transportation and other related businesses. A 10% increase in the value of equity securities underlying the short sale positions of the Company as of December 31, 2010 would reduce income by $2.3 million, net of tax.

The Company held positions in publicly traded equity options that may convey to the Company a right or obligation to engage in a future transaction with respect to the underlying equity security. The Company’s investment in equity options primarily includes positions in energy, marine, transportation and other related businesses. These investments have short-term maturities and their market values fluctuate based on changes in the price and volatility of the underlying security, the strike price of the option and the time to expiration. As of December 31, 2010, the Company had a liability of $1.5 million having marked to market its positions in these publicly traded equity options.

The Company has entered into and settled various positions in forward currency exchange, option and future contracts which could offset possible consequences of changes in foreign exchange rates with respect to the Company’s business conducted in Europe, Africa, Latin America, the Middle East and Asia. As of December 31, 2010, the outstanding forward currency exchange contract positions translate to a net purchase of foreign currencies with an aggregate U.S. dollar equivalent of $135.3 million. As of December 31, 2010, the Company had capital purchase commitments of €121.3 million and had designated €56.0 million ($74.2 million) of its forward currency exchange contracts as fair value hedges. For those forward currency exchange contract positions not designated as fair value hedges, an adverse change of 10% in the underlying foreign currency exchange rates would reduce income by $4.1 million, net of tax. In addition, the Company maintained cash balances of €48.1 million as of December 31, 2010.

The Company’s outstanding debt is primarily in fixed interest rate instruments. Although the fair value of these debt instruments will vary with changes in interest rates, the Company’s operations are not significantly affected by interest rate fluctuations. As of December 31, 2010, the Company had $125.0 million of variable rate borrowings, based on LIBOR, under its revolving credit facility. During the year ended December 31, 2010, the Company held various interest rate swap agreements, designated as cash flow hedges, to fix the interest rate on these borrowings at an average rate of 3.1%. Additionally, as of December 31, 2010, the Company had other variable rate debt (due 2012 through 2016) totaling $63.1 million. These instruments call for the Company to pay interest based on LIBOR plus a 260-300 basis point margin. The interest rates reset either monthly or quarterly. One instrument is subject to a floor of 4.5%. As of December 31, 2010, the average interest rate on these borrowings was 3.5%.

As of December 31, 2010 the Company had interest rate swap agreements, other than those designated as cash flow hedges mentioned above, with a notional value of $76.5 million. These agreements call for the Company to pay a fixed interest rate ranging from 1.79% to 2.59% and receive interest payments based on LIBOR. As of December 31, 2010, the Company had a liability of $2.6 million having marked to market its positions in these interest rate swap agreements.

The Company has entered into and settled positions in various exchange and non-exchange traded commodity swap, option and future contracts. In the Company’s commodity trading and logistics business, fixed price future purchase and sale contracts of ethanol and sugar are included in the Company’s non-exchange traded derivative positions. The Company enters into exchange traded positions to protect these purchase and sales contracts as well as its inventory balances from market changes. As of December 31, 2010, the net market exposure to ethanol and sugar under these positions was not material. The Company also enters into exchange traded positions (primarily natural gas, crude oil, gasoline, ethanol and sugar) to provide value to the Company should there be a sustained decline in the price of commodities that could lead to a reduction in the market values and cash flows of the Company’s offshore marine and inland river businesses. As of December 31, 2010, these positions were not material. As of December 31, 2010, the fair value of these exchange and non-exchange based commodity contracts was a liability of $2.4 million, net.

The Company has entered into and settled various positions in U.S. treasury notes and bonds through rate locks, futures or options on futures tied to U.S. treasury notes. The general purpose of these transactions is to provide value to the Company should the price of U.S. treasury notes and bonds decline, leading to generally higher interest rates, which might lead to higher interest costs for the Company. As of December 31, 2010, these positions consist primarily of treasury futures with a notional value of $50.0 million and a one-year rate lock agreement with a notional value of $100.0 million. The treasury rate lock agreement provides for a net cash settlement in October 2011 based on the then current ten-year U.S. Treasury Note versus the agreement rate of 2.845%. As of December 31, 2010, the fair value of these positions was a recorded asset of $10.5 million. An adverse change of 10% in the underlying treasury rate would reduce income by $2.8 million, net of tax.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

SEACOR Holdings Inc.’s (“SEACOR”) management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934).

Management conducted an evaluation of the effectiveness of its internal control over financial reporting as of December 31, 2010 based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. This evaluation included a review of the documentation surrounding SEACOR’s financial controls, an evaluation of the design effectiveness of these controls, testing of the operating effectiveness of these controls and a conclusion on this evaluation. Although there are inherent limitations in the effectiveness of any system of internal control over financial reporting—including the possibility of the circumvention or overriding of controls—based on management’s evaluation, management has concluded that SEACOR’s internal control over financial reporting was effective as of December 31, 2010. However, because of changes in conditions, it is important to note that internal control system effectiveness may vary over time.

SEACOR’s internal control over financial reporting as of December 31, 2010 has been audited by Ernst & Young LLP, the independent registered public accounting firm that has also audited SEACOR’s consolidated financial statements included in this Annual Report on Form 10-K. Ernst & Young LLP’s report on SEACOR’s internal control over financial reporting is included elsewhere herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The Stockholders and Board of Directors of SEACOR Holdings Inc.

We have audited SEACOR Holdings Inc.’s internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). SEACOR Holdings Inc.’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 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 its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that 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, SEACOR Holdings Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of SEACOR Holdings Inc. as of December 31, 2010 and 2009, and the related consolidated statements of income, changes in equity and cash flows for each of the three years in the period ended December 31, 2010 of SEACOR Holdings Inc. and our report dated February 25, 2011 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Stockholders and Board of Directors of SEACOR Holdings Inc.

We have audited the accompanying consolidated balance sheets of SEACOR Holdings Inc. (the Company) as of December 31, 2010 and 2009, and the related consolidated statements of income, changes in equity and cash flows for each of the three years in the period ended December 31, 2010. Our audits also included the financial statement schedule listed in the Index at Item 15(a). These financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and 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, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of SEACOR Holdings Inc. as of December 31, 2010 and 2009, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2010, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), SEACOR Holdings Inc.’s internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 25, 2011 expressed an unqualified opinion thereon.

SEACOR HOLDINGS INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. NATURE OF OPERATIONS AND ACCOUNTING POLICIES

Nature of Operations. SEACOR Holdings Inc. (“SEACOR”) and its subsidiaries (collectively referred to as the “Company”) are in the business of owning, operating, investing in and marketing equipment, primarily in the offshore oil and gas, industrial aviation and marine transportation industries. The Company operates a diversified fleet of offshore support vessels and helicopters servicing oil and gas exploration, development and production facilities worldwide and a fleet of U.S.-flag product tankers that transport petroleum, chemicals and crude products primarily in the U.S. domestic or “coastwise” trade. In addition, the Company operates a fleet of inland river barges and towboats transporting grain, liquids and other bulk commodities on the U.S. Inland River Waterways. The Company’s environmental services segment primarily provides emergency preparedness and response services to oil, chemical, industrial and marine transportation clients, and government agencies in the United States and abroad. The Company’s commodity trading and logistics segment is an integrated business involved in the purchase, storage, transportation, processing and sale of agricultural and energy commodities.

Basis of Consolidation. The consolidated financial statements include the accounts of SEACOR and its majority-owned subsidiaries. All significant inter-company accounts and transactions are eliminated in consolidation.

Noncontrolling interests are included in the consolidated statement of financial position within equity separate from the Company’s equity. The Company also reports consolidated net income inclusive of both the Company’s and the noncontrolling interests’ shares and, separately, the amounts of consolidated net income attributable to the Company and noncontrolling interests. If a subsidiary is deconsolidated upon a change in control, any retained noncontrolling equity investment in the former subsidiary is measured at fair value and a gain or loss is recognized in net income based on such fair value. If a noncontrolled subsidiary is consolidated upon a change in control, any previous noncontrolling equity investment in the subsidiary is measured at fair value and a gain or loss is recognized in equity in earnings based on such fair value.

The Company employs the equity method of accounting for investments in business ventures when it has the ability to exercise significant influence over the operating and financial policies of the ventures. Significant influence is generally deemed to exist if the Company has between 20% and 50% of the voting rights of an investee. The Company reports its investments in and advances to equity investees in the accompanying consolidated balance sheets as investments, at equity, and advances to 50% or less owned companies. The Company reports its share of earnings or losses of equity investees in the accompanying consolidated statements of income as equity in earnings of 50% or less owned companies, net of tax.

The Company employs the cost method of accounting for investments in other business ventures over which the Company does not have the ability to exercise significant influence. These investments in private companies are carried at cost and are adjusted only for capital distributions and other-than-temporary declines in fair value.

Use of Estimates. 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates include those related to deferred revenues, allowance for doubtful accounts, useful lives of property and equipment, impairments, income tax provisions and certain accrued liabilities. Actual results could differ from those estimates and those differences may be material.

Revenue Recognition. The Company recognizes revenue when it is realized or realizable and earned. Revenue is realized or realizable and earned when persuasive evidence of an arrangement exists, delivery has

102

occurred or services have been rendered, the price to the buyer is fixed or determinable, and collectability is reasonably assured. Revenue that does not meet this criteria is deferred until the criteria are met. Deferred revenues for the years ended December 31 were as follows (in thousands):

	2010			2009			2008
Balance at beginning of year	$	15,015		$	3,314		$	2,472
Revenues deferred during the year		20,259			24,803			2,469
Revenues recognized during the year		(5,902	)		(13,102	)		(39	)
Write-off of previously deferred revenues		(50	)		—			(1,588	)
Balance at end of year	$	29,322		$	15,015		$	3,314

As of December 31, 2010, deferred revenues included $18.8 million relating to the time charter of several offshore support vessels operating in the U.S. Gulf of Mexico that are scheduled to be paid through the conveyance of a limited net profit interest in developmental oil-and-gas producing properties owned by a customer. Payments from the conveyance of the limited net profit interest, and the timing of such payments, are contingent upon production and energy sale prices. Based on the current production payout estimate, the deferred revenues are expected to be paid during 2011. The Company will continue to recognize revenues as cash is received or earlier should future payments become determinable. All costs and expenses related to these charters were recognized as incurred.

As of December 31, 2010, deferred revenues also included $8.5 million related to audit provisions in Environmental Services’ response services contracts. The amount of revenues ultimately recognized following the completion of the billing audits or the expiration of the audit period could differ from the amounts billed and those differences may be material.

The Company’s Offshore Marine Services segment earns and recognizes revenues primarily from the time charter and bareboat charter of vessels to customers based upon daily rates of hire. Under a time charter, Offshore Marine Services provides a vessel to a customer and is responsible for all operating expenses, typically excluding fuel. Under a bareboat charter, Offshore Marine Services provides the vessel to the customer and the customer assumes responsibility for all operating expenses and risk of operation. Vessel charters may range from several days to several years. Revenues from time charters and bareboat charters are recorded and recognized as services are provided. In the U.S. Gulf of Mexico, time charter durations and rates are typically established in the context of master service agreements, which govern the terms and conditions of charter.

The Company’s Aviation Services segment charters its helicopters to utility and oil and gas customers primarily through master service agreements, term contracts, day-to-day charter arrangements and leases. Master service agreements require incremental payments above a fixed rental fee based upon flight hours flown, have fixed terms ranging from one month to five years and generally are cancelable upon 30 days notice. Term contracts and day-to-day charter arrangements are generally non-cancelable without cause and call for a combination of a monthly or daily fixed rental fee plus a charge based on hours flown. Day-to-day charter arrangements are generally based on either an hourly or daily rate. Leases can be either dry, providing only the equipment, or wet, providing equipment, insurance and personnel. Fixed rental fee revenues are recognized ratably over the contract term. Usage or hourly based revenues are recognized as hours are flown. Aviation Services’ air medical activities are provided under contracts with hospitals that typically include either a fixed monthly and hourly rate structure or a fee per completed flight. Fixed monthly revenues are recognized ratably over the month while per hour or per flight based revenues are recognized as hours are flown or flights are completed. The Company’s air medical activities are provided under contracts with hospitals that typically include either a fixed monthly and hourly rate structure, similar to oil and gas, or a fee per completed flight. Fixed monthly revenues are recognized ratable over the month while per hour or per flight based revenues are recognized as hours are flown or flights are completed. Most contracts with hospitals are longer term, but offer

103

either party the ability to terminate with less than six months notice. The Company operates some air medical contracts pursuant to which it collects a fee per flight, either from a hospital or insurance company. With respect to flightseeing activities, Aviation Services allocates block space to cruise lines and sells seats directly to customers with revenues for helicopter usage recognized as the services are performed.

The Company’s Inland River Services segment earns revenues primarily from voyage affreightment contracts whereby customers are charged an established rate per ton to transport cargo from point to point. Revenues from voyage affreightment contracts are generally recognized over the progress of the voyage while the related costs are expensed as incurred. Certain of Inland River Services’ barges are operated in barge pools with other barges owned by third parties from whom Inland River Services earns and recognizes a management fee as the services are rendered. Pursuant to the pooling agreements, operating revenues and expenses of participating barges are combined and the net results are allocated on a pro-rata basis based on the number of barge days contributed by each participant. In addition, revenues are earned from equipment chartered to third parties and from the storage and demurrage of cargos associated with affreightment activities. In both of these cases, revenues are recognized as services are rendered. Inland River Services’ tank farm and handling facility earns revenues through rental and throughput charges. Rental revenues are recognized ratably over the rental period while throughput charges are recognized as product volume moves through the facility.

The Company’s Marine Transportation Services segment earns revenue from the time charter, bareboat charter and voyage charter of vessels and under contracts of affreightment. Under a time charter, Marine Transportation Services provides a vessel to a customer and is responsible for all operating expenses, typically excluding fuel. Under a bareboat charter, Marine Transportation Services provides the vessel to a customer and the customer assumes responsibility for all operating expenses and risk of operation. Revenues from time charters and bareboat charters are recognized as services are provided. Voyage contracts are contracts to carry cargos on a single voyage basis regardless of time to complete. Contracts of affreightment are contracts for cargos that are committed on a multi-voyage basis for various periods of time with minimum and maximum cargo tonnages specified over the period at a fixed or escalating rate per ton. Revenues for voyage contracts and contracts of affreightment are recognized over the progress of the voyage while the related costs are expensed as incurred.

The Company’s Environmental Services segment earns revenues primarily from emergency response, retainer, consulting and training, project management and remediation services. Emergency response revenues are recognized as services are provided and are dependent on the magnitude and number of individual responses. Retainer agreements with vessel owners generally range from one to three years while retainer agreements with facility owners can be as long as ten years. Such retainer fees are generally recognized ratably over the term of the contract. Consulting and training services fees are recognized as the services are provided based on the contract terms. Project management and remediation services are provided on a time and material basis with revenues recognized as the services are provided or on a fixed fee bid basis with revenues and expenses recognized upon completion of the contract.

The Company’s Commodity Trading and Logistics segment earns revenues from the sale of rice, sugar and renewable fuels (primarily ethanol), the rental of tank storage, and through voyage affreightment contracts on leased-in liquid tank barges and towboats. Revenues from rice, sugar and renewable fuel sales are recorded when title transfers to the buyer, typically when cash is received. Revenues from the rental of tank storage are recognized ratably over the lease periods. Revenues from voyage affreightment contracts are generally recognized over the progress of the voyage while the related costs are expensed as incurred.

Cash Equivalents. The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Cash equivalents consist of U.S treasury securities, money market instruments, time deposits and overnight investments.

104

Restricted Cash. Restricted cash, consisting primarily of U.S. treasury securities, relates to income generated from the operations of certain of Marine Transportation Services’ U.S.-flag double-hull product tankers (see Note 8).

Marketable Securities. Marketable equity securities with readily determinable fair values and debt securities are reported in the accompanying consolidated balance sheets as marketable securities. These investments are stated at fair value with, effective October 1, 2008 (see discussion below), both realized and unrealized gains and losses reported in the accompanying consolidated statements of income as marketable security gains (losses), net. Short sales of marketable securities are stated at fair value in the accompanying consolidated balance sheets with both realized and unrealized gains and losses reported in the accompanying consolidated statements of income as marketable security gains (losses), net.

Effective October 1, 2008, the Company designated its investments in marketable equity and debt securities as trading securities and transferred securities of $72.9 million with net unrealized holding losses of $4.6 million from their previous available-for-sale designation. Prior to this transfer, unrealized gains and losses on available-for-sale marketable equity and debt securities were reported in other comprehensive income (loss) and realized gains and losses on available-for-sale marketable equity and debt securities were reported in the accompanying consolidated statements of income as marketable security gains (losses), net.

Trade Receivables. Customers of Offshore Marine Services, Aviation Services and Marine Transportation Services are primarily major and independent oil and gas exploration and production companies. Customers of Inland River Services are primarily major agricultural and industrial companies based within the United States. Oil spill, emergency response and remediation services are provided by Environmental Services to domestic and international shippers, major oil companies, independent exploration and production companies, pipeline and transportation companies, power generating operators, industrial companies, airports and state and local government agencies. Customers of Commodity Trading and Logistics include major agricultural and industrial companies, major and independent oil and gas production companies, foreign governments and local distributors. All customers are granted credit on a short-term basis and related credit risks are considered minimal. The Company routinely reviews its trade receivables and makes provisions for probable doubtful accounts; however, those provisions are estimates and actual results could differ from those estimates and those differences may be material. Trade receivables are deemed uncollectible and removed from accounts receivable and the allowance for doubtful accounts when collection efforts have been exhausted.

Derivative Instruments. The Company accounts for derivatives through the use of a fair value concept whereby all of the Company’s derivative positions are stated at fair value in the accompanying consolidated balance sheets. Realized and unrealized gains and losses on derivatives not designated as hedges are reported in the accompanying consolidated statements of income as derivative gains (losses), net. Realized and unrealized gains and losses on derivatives designated as fair value hedges are recognized as corresponding increases or decreases in the fair value of the underlying hedged item to the extent they are effective, with any ineffective portion reported in the accompanying consolidated statements of income as derivative gains (losses), net. Realized and unrealized gains and losses on derivatives designated as cash flow hedges are reported as a component of other comprehensive income in the accompanying consolidated statement of changes in equity to the extent they are effective and reclassified into earnings on the same line item associated with the hedged transaction and in the same period the hedged transaction affects earnings. Any ineffective portion of cash flow hedges are reported in the accompanying consolidated statements of income as derivative gains (losses), net. Realized and unrealized gains and losses on derivatives designated as cash flow hedges that are entered into by the Company’s equity method investees are also reported as a component of the Company’s other comprehensive income (loss) in proportion to the Company’s ownership percentage in the investee, with reclassifications and ineffective portions being included in equity in earnings of 50% or less owned companies, net of tax, in the accompanying consolidated statements of income.

Concentrations of Credit Risk. The Company is exposed to concentrations of credit risk associated with its cash and cash equivalents, restricted cash, marketable securities and derivative instruments. The Company

105

minimizes its credit risk relating to these positions by monitoring the financial condition of the financial institutions and counterparties involved and by primarily conducting business with large, well-established financial institutions and diversifying its counterparties. The Company does not currently anticipate nonperformance by any of its significant counterparties. The Company is also exposed to concentrations of credit risk relating to its receivables due from customers in the industries described above. The Company does not generally require collateral or other security to support its outstanding receivables. The Company minimizes its credit risk relating to receivables by performing ongoing credit evaluations and, to date, credit losses have not been material.

Inventories. Inventories are stated at the lower of cost (using the first-in, first-out method) or market. Inventories consist primarily of fuel and fuel oil in the Company’s Offshore Marine Services, Marine Transportation Services and Inland River Services segments, spare parts and fuel in the Company’s Aviation Services segment, and ethanol in the Company’s Commodity Trading and Logistics segment. The Company records write-downs, as needed, to adjust the carrying amount of inventories to the lower of cost or market. During the years ended December 31, 2010 and 2008, the Company recorded write-downs of $1.8 million and $1.0 million, respectively, related to Commodity Trading and Logistics’ rice inventory. There were no inventory write-downs during 2009.

Property and Equipment. Equipment, stated at cost, is depreciated using the straight line method over the estimated useful life of the asset to an estimated salvage value. With respect to each class of asset, the estimated useful life is typically based upon a newly built asset being placed into service and represents the point at which it is typically not justifiable for the Company to continue to operate the asset in the same or similar manner. From time to time, the Company may acquire older assets that have already exceeded the Company’s useful life policy, in which case the Company depreciates such assets based on its best estimate of remaining useful life, typically the next survey or certification date.

As of December 31, 2010, the estimated useful life (in years) of each of the Company’s major classes of new equipment was as follows:

Offshore support vessels	20
Helicopters	12
Inland river dry cargo and deck barges	20
Inland river liquid tank barges	25
Inland river towboats	25
U.S.-flag tankers(1)	25
Harbor and offshore tugs(2)	25
Ocean liquid tank barges	25

(1) Subject to Oil Pollution Act of 1990 (“OPA 90”) requirements.

(2) Effective April 1, 2008, the Company changed its estimated useful life for newly built harbor and offshore tugs from 40 to 25 years and reduced the remaining useful life of certain vessels within its harbor and offshore tug fleet due to the more frequent occurrence of technological advancements in vessel design. These changes in estimates did not materially impact the comparability of financial information for the periods presented.

The Company’s major classes of property and equipment as of December 31 were as follows (in thousands):

	Historical Cost(1)		Accumulated Depreciation			Net Book Value

(1) Includes property and equipment acquired in business acquisitions and recorded at fair value as of the date of the acquisition.

Depreciation expense totaled $158.3 million, $155.1 million and $150.9 million in 2010, 2009 and 2008, respectively.

Equipment maintenance and repair costs and the costs of routine overhauls, drydockings and inspections performed on vessels and equipment are charged to operating expense as incurred. Expenditures that extend the useful life or improve the marketing and commercial characteristics of equipment as well as major renewals and improvements to other properties are capitalized. Certain third party vendors maintain helicopter components and engines on some of the Company’s helicopters under programs that require the Company to pay ratably for the service based on flight hours flown. These costs are normally billed monthly and expensed as incurred. In the event the Company places a helicopter in a program after a maintenance period has begun, it may be necessary to pay an initial buy-in charge based on hours flown to date with such charge being amortized over the contract period. If a helicopter is sold before the scheduled maintenance work is carried out, the Company may be able to recover part of the expenditure incurred up to that point. The impact of the entry into and exit from these programs could have a significant impact on the Company’s repair and maintenance costs.

Certain interest costs incurred during the construction of equipment are capitalized as part of the assets’ carrying values and are amortized over such assets estimated useful lives. Capitalized interest totaled $3.6 million, $2.3 million and $7.7 million in 2010, 2009 and 2008, respectively.

Intangible Assets. The Company’s intangible assets primarily arose from business acquisitions (see Note 4) and consist of non-compete agreements, trademarks and tradenames, customer relationships, software and technology and acquired contractual rights. These intangible assets are amortized over their estimated useful

107

lives ranging from two to ten years. During the years ended December 31, 2010, 2009 and 2008, the Company recognized amortization expense of $5.2 million, $5.0 million and $5.5 million, respectively.

The Company’s intangible assets by type were as follows (in thousands):

Impairment of Long-Lived Assets. The Company performs an impairment analysis of long-lived assets used in operations, including intangible assets, when indicators of impairment are present. If the carrying values of the assets are not recoverable, as determined by the estimated undiscounted cash flows, the carrying values of the assets are reduced to fair value. Generally, fair value is determined using valuation techniques, such as expected discounted cash flows or appraisals, as appropriate. During the years ended 2010, 2009 and 2008, the Company recognized impairment charges of $19.0 million, $2.3 million and $1.1 million, respectively, related to long-lived assets held for use.

108

The Company believes the Seabulk America is one of six vessels designed and certified to carry complicated chemical cargos in the domestic coastwise trade. As previously reported, the Seabulk America had been scheduled to undergo a regulatory drydocking during the third quarter of 2010, a requirement for continued operation. Given the prevailing market conditions, the Company deferred the drydocking, laid-up the vessel and recognized an impairment charge of $18.7 million reducing the vessel’s carrying value to its fair value of $5.0 million. The Seabulk America contributed operating revenues of $5.2 million, $12.4 million and $16.0 million for the years ended December 31, 2010, 2009, 2008, respectively.

Impairment of 50% or Less Owned Companies. The Company performs regular reviews of each investee’s financial condition, the business outlook for its products and services, and its present and projected results and cash flows. When an investee has experienced consistent declines in financial performance or difficulties in raising capital to continue operations, and when the Company expects the decline to be other-than-temporary, the investment is written down to fair value. Actual results may vary from estimates due to the uncertainty regarding the projected financial performance of investees, the severity and expected duration of declines in value, and the available liquidity in the capital markets to support the continuing operations of the investees in which the Company has investments. During the year ended December 31, 2009, the Company recognized impairment charges of $1.1 million related to 50% or less owned companies. The Company did not recognize any impairment charges in 2010 or 2008.

Goodwill. Goodwill is recorded when the purchase price paid for an acquisition exceeds the fair value of net identified tangible and intangible assets acquired. The Company performs an annual impairment test of goodwill and further periodic tests to the extent indicators of impairment develop between annual impairment tests. The Company’s impairment review process compares the fair value of the reporting unit to its carrying value, including the goodwill related to the reporting unit. To determine the fair value of the reporting unit, the Company uses a discounted future cash flow approach that uses estimates for revenues, costs and appropriate discount rates, among others. These estimates are reviewed each time the Company tests goodwill for impairment and are typically developed as part of the Company’s routine business planning and forecasting process. While the Company believes its estimates and assumptions are reasonable, variations from those estimates could produce materially different results. The Company did not recognize any goodwill impairments in 2010, 2009 or 2008.

Business Combinations. Effective January 1, 2009, the Company adopted new accounting rules established by the Financial Accounting Standards Board (“FASB”) related to business combinations. The new accounting rules amended the Company’s accounting policy by requiring the Company to recognize on its future acquisitions, with certain exceptions, 100 percent of the fair value of assets acquired, liabilities assumed, and non-controlling interests when the acquisition constitutes a change in control of the acquired entity. The new accounting rules establish that shares issued in consideration for a business combination be at fair value on the acquisition date, requires the recognition of contingent consideration arrangements at their acquisition-date fair values with subsequent changes in fair value generally reflected in earnings, and requires recognition of pre-acquisition loss and gain contingencies at their acquisition-date fair values. The new accounting rules also provide for the capitalization of in-process research and development assets acquired, requires acquisition-related transaction costs to be expensed as incurred, allows for the capitalization of acquisition-related restructuring costs only if the criteria in the FASB rules related to exit or disposal cost obligations are met as of the acquisition date, and requires as an adjustment to income tax expense any changes in an acquirer’s existing income tax valuation allowances and tax uncertainty accruals. The operating results of entities acquired are included in the accompanying consolidated statements of income from the date of acquisition (see Note 4).

Deferred Financing Costs. Deferred financing costs incurred in connection with the issuance of debt are amortized over the life of the related debt using the effective interest rate method. Amortization expense for deferred financing costs totaled $0.5 million, $1.0 million and $0.7 million in 2010, 2009 and 2008, respectively, and is included in interest expense in the accompanying consolidated statements of income.

Self-insurance Liabilities. The Company maintains hull, liability and war risk, general liability, workers compensation and other insurance customary in the industries in which it operates. Most of the insurance is obtained through SEACOR sponsored programs, with premiums charged to participating businesses based on insured asset values. Both the marine hull and liability policies have significant annual aggregate deductibles. Marine hull annual aggregate deductibles are accrued as claims are incurred by participating businesses and proportionately shared among the participating businesses. Marine liability annual aggregate deductibles are accrued based on historical loss experience and actual claims incurred. The Company also maintains self-insured health benefit plans for its participating employees. Exposure to the health benefit plans are limited by maintaining stop-loss and aggregate liability coverage. To the extent that estimated self-insurance losses, including the accrual of annual aggregate deductibles, differ from actual losses realized, the Company’s insurance reserves could differ significantly and may result in either higher or lower insurance expense in future periods.

Income Taxes. Deferred income tax assets and liabilities have been provided in recognition of the income tax effect attributable to the book and tax basis differences of assets and liabilities reported in the accompanying consolidated financial statements. Deferred tax assets or liabilities are provided using the enacted tax rates expected to apply to taxable income in the periods in which they are expected to be settled or realized. Interest and penalties relating to uncertain tax positions are recognized in interest expense and administrative and general, respectively, in the accompanying consolidated statements of income. The Company records a valuation allowance to reduce its deferred tax assets if it is more likely than not that some portion or all of the deferred tax assets will not be realized.

Deferred Gains—Vessel Sale-Leaseback Transactions and Financed Vessel Sales. From time to time, the Company enters into vessel sale-leaseback transactions with finance companies or provides seller financing on sales of its vessels to third parties. A portion of the gains realized from these transactions is not immediately recognized in income and has been recorded in the accompanying consolidated balance sheets in deferred gains and other liabilities. In sale-leaseback transactions (see Note 4), gains are deferred to the extent of the present value of future minimum lease payments and are amortized as reductions to rental expense over the applicable lease terms. In financed vessel sales, gains are deferred to the extent that the repayment of purchase notes is dependent on the future operations of the sold vessels and are amortized based on cash received from the buyers. Deferred gain activity related to these transactions for the years ended December 31 was as follows (in thousands):

	2010			2009			2008

Deferred Gains—Vessel Sales to the Company’s 50% or Less Owned Companies. A portion of the gains realized from the sales of the Company’s vessels, helicopters and barges to its 50% or less owned companies is not immediately recognized in income and has been recorded in the accompanying consolidated balance sheets in deferred gains and other liabilities. Effective January 1, 2009, the Company adopted new accounting rules established by the FASB relating to the sale of its equipment to its noncontrolled 50% or less owned companies. For transactions occurring subsequent to the adoption of the new accounting rules, gains are deferred only to the extent of the Company’s uncalled capital commitments and amortized as those commitments lapse or funded

110

amounts are returned by the noncontrolled 50% or less owned companies. For transactions occurring prior to the adoption of the new accounting rules, gains were deferred and are being amortized based on the Company’s ownership interest, the Company’s uncalled capital commitments, cash received and the applicable vessels’ depreciable lives. Deferred gain activity related to these transactions for the years ended December 31 was as follows (in thousands):

	2010			2009			2008

Stock Based Compensation. Stock based compensation is amortized to compensation expense on a straight line basis over the requisite service period of the grants using the Black-Scholes valuation model. The Company will reconsider its use of this model if additional information becomes available in the future that indicates another model would be more appropriate, or if grants issued in future periods have characteristics that cannot be reasonably estimated using this model. The Company does not estimate forfeitures in its expense calculations as forfeiture history has been minor. The Company presents the excess tax benefits from the exercise of stock options as a financing cash flow in the accompanying consolidated statements of cash flows.

Foreign Currency Translation. The assets, liabilities and results of operations of certain SEACOR subsidiaries are measured using their functional currency which is the currency of the primary foreign economic environment in which they operate. Upon consolidating these subsidiaries with SEACOR, their assets and liabilities are translated to U.S. dollars at currency exchange rates as of the balance sheet date and their revenues and expenses are translated at the weighted average currency exchange rates during the applicable reporting periods. Translation adjustments resulting from the process of translating these subsidiaries’ financial statements are reported in other comprehensive income (loss) in the accompanying consolidated statements of changes in equity.

Foreign Currency Transactions. Certain SEACOR subsidiaries enter into transactions denominated in currencies other than their functional currency. Changes in currency exchange rates between the functional currency and the currency in which a transaction is denominated are included in foreign currency gains (losses), net in the accompanying consolidated statements of income in the period in which the currency exchange rates change.

Earnings Per Share. Basic earnings per common share of SEACOR are computed based on the weighted average number of common shares issued and outstanding during the relevant periods. Diluted earnings per common share of SEACOR are computed based on the weighted average number of common shares issued and outstanding plus the effect of potentially dilutive securities through the application of the treasury stock and if-converted methods. Dilutive securities for this purpose assumes restricted stock grants have vested, common shares have been issued pursuant to the exercise of outstanding stock options and common shares have been issued pursuant to the conversion of all outstanding convertible notes. For the years ended December 31, 2010, 2009 and 2008, diluted earnings per common share of SEACOR excluded 281,265, 810,260 and 650,757, respectively, of certain share awards as the effect of their inclusion in the computation would have been antidilutive.

2. FAIR VALUE MEASUREMENTS

The fair value of an asset or liability is the price that would be received to sell an asset or transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company utilizes a fair value hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value and defines three levels of inputs that may be used to measure fair value. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are observable inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, quoted prices in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, or inputs derived from observable market data. Level 3 inputs are unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities.

113

The Company’s financial assets and liabilities as of December 31, 2010 that are measured at fair value on a recurring basis were as follows (in thousands):

	Level 1		Level 2		Level 3
ASSETS
Marketable securities(1)	$	101,807	$	45,602	$	—
Derivative instruments (included in other receivables)		14,006		8,158		—
Construction reserve funds and Title XI reserve funds		323,885		—		—
LIABILITIES
Short sales of marketable securities		36,076		—		—
Derivative instruments (included in other current liabilities)		11,555		9,455		—

(1) Marketable security gains (losses), net include losses of $1.1 million and gains of $0.9 million for the years ended December 31, 2010 and 2009, respectively, related to marketable security positions held by the Company as of December 31, 2010. Marketable security gains (losses), net include losses of $2.2 million for the three months ended December 31, 2008 (period subsequent to portfolio designation as trading securities—see Note 1) related to marketable security positions held by the Company as of December 31, 2010.

The estimated fair value of the Company’s other financial assets and liabilities as of December 31 were as follows (in thousands).

	2010				2009
	Carrying Amount		Estimated Fair Value		Carrying Amount		Estimated Fair Value
ASSETS
Cash, cash equivalents and restricted cash	$	382,679	$	382,679	$	499,918	$	499,918
Investments, at cost, in 50% or less owned companies (included in other assets)		7,847		see below		7,506		see below
Notes receivable from other business ventures (included in other assets)		13,335		see below		11,343		see below
LIABILITIES
Long-term debt, including current portion		712,045		722,014		785,140		783,423

The carrying value of cash, cash equivalents and restricted cash approximates fair value. The fair value of the Company’s long-term debt was estimated based upon quoted market prices or by using discounted cash flow analyses based on estimated current rates for similar types of arrangements. It was not practicable to estimate the fair value of the Company’s investments, at cost, in 50% or less owned companies because of the lack of quoted market prices and the inability to estimate fair value without incurring excessive costs. It was not practicable to estimate the fair value of the Company’s notes receivable from other business ventures because the timing of settlement of these notes is not certain and the inability to estimate fair value without incurring excessive costs. Considerable judgment was required in developing certain of the estimates of fair value and, accordingly, the estimates presented herein are not necessarily indicative of the amounts that the Company could realize in a current market exchange.

114

The Company’s non-financial assets and liabilities that were measured at fair value during the year ended December 31, 2010 were as follows (in thousands):

	Level 1		Level 2		Level 3
ASSETS
Investment in Seaspraie(1)	$	—	$	56,255	$	—

(1) During the year ended December 31, 2010, the Company marked its investment in its Seaspraie joint venture to fair value following the acquisition of a controlling interest (see Note 4). The investment’s fair value, consisting of barges and financial assets, was primarily based on the sale of similar equipment to an unrelated third party.

(2) During the year ended December 31, 2010, the Company recorded an impairment charge of $18.7 million to reduce the carrying value of one of its tankers, the Seabulk America, to its fair value (see Note 5). Fair value was determined by an independent market valuation based on the sale of similar equipment.

(3) During the year ended December 31, 2010, the Company marked its investment in its SES-Kazakhstan joint venture, to fair value following the acquisition of a controlling interest (see Note 4). The investment’s fair value was determined based on the Company’s purchase price of the non-controlling interest.

(4) During the year ended December 31, 2010, the Company recorded an impairment charge of $0.1 million to reduce its carrying value of one helicopter to fair value.

(5) During the year ended December 31, 2010, the Company recorded an impairment charge of $0.2 million to increase the carrying value of its exit obligations for three leased-in helicopters.

3. DERIVATIVE INSTRUMENTS AND HEDGING STRATEGIES

Derivative instruments are classified as either assets or liabilities based on their individual fair values. Derivative assets and liabilities are included in other receivables and other current liabilities, respectively, in the accompanying consolidated balance sheets.

Fair Value Hedges. As of December 31, 2010 and 2009, the Company designated certain of its forward currency exchange contracts with notional values of €56.0 million and €16.0 million, respectively, as fair value hedges in respect of capital commitments denominated in euros. By entering into these forward currency exchange contracts, the Company has fixed a portion of its euro capital commitments in U.S. dollars to protect against currency fluctuations for equipment scheduled to be delivered in 2011 through 2013. During the year ended December 31, 2010, the Company designated €68.0 million and dedesignated €8.2 million notional value of its forward currency exchange contracts as fair value hedges, and €19.8 million notional value of these contracts matured.

The Company recognized gains (losses) on derivative instruments designated as fair value hedges for the years ended December 31 as follows (in thousands):

	Derivative gains (losses), net

Cash Flow Hedges. As of December 31, 2010 and 2009, the Company is a party to various interest rate swap agreements with maturities ranging from 2013 to 2014 that have been designated as cash flow hedges. These agreements call for the Company to pay fixed interest rates ranging from 2.25% to 2.85% on aggregate notional values of $125.0 million and receive a variable interest rate based on LIBOR on these notional values. During the year ended December 31, 2010, one of the Company’s Offshore Marine Services 50% or less owned companies entered into an interest rate swap agreement maturing in 2015 that has been designated as a cash flow hedge. This instrument calls for the joint venture to pay a fixed interest rate of 1.48% on the amortized notional value of $21.0 million and receive a variable interest rate based on LIBOR on the amortized notional value. By entering into these interest rate swap agreements, the Company and its joint venture have converted the variable LIBOR component of certain of their outstanding borrowings to a fixed interest rate. During the year ended December 31, 2010, another of the Company’s Offshore Marine Services 50% or less owned companies dedesginated its interest rate swap as a cash flow hedge.

The Company recognized gains (losses) on derivative instruments designated as cash flow hedges for the years December 31 as follows (in thousands):

The Company holds positions in publicly traded equity options that convey the right or obligation to engage in a future transaction on the underlying equity security or index. The Company’s investment in equity options primarily includes positions in energy, marine, transportation and other related businesses. These contracts are typically entered into to mitigate the risk of changes in market value of marketable security positions that the Company is either about to acquire, has acquired or is about to dispose of.

The Company has entered into and settled forward currency exchange, option and future contracts with respect to various foreign currencies. As of December 31, 2010, the outstanding forward currency exchange contracts translated into a net purchase of foreign currencies with an aggregate U.S. dollar equivalent of $61.2 million. These contracts enable the Company to buy currencies in the future at fixed exchange rates, which could offset possible consequences of changes in foreign exchange rates with respect to the Company’s business conducted in Europe, Africa, Mexico, Central and South America, the Middle East and Asia. The Company generally does not enter into contracts with forward settlement dates beyond twelve to eighteen months.

The Company has entered into various interest rate swap agreements maturing in 2012 and 2013 that call for the Company to pay fixed interest rates ranging from 1.79% to 2.59% on aggregate notional values of $69.6 million and receive a variable interest rate based on LIBOR on these notional values. In addition, one of the Company’s Offshore Marine Services 50% or less owned companies has entered into an interest rate swap agreement maturing in 2014. This instrument calls for the joint venture to pay a fixed interest rate of 3.05% on the amortized notional value of $27.2 million and receive a variable interest rate based on LIBOR on the amortized notional value. The general purpose of these interest rate swap agreements is to provide protection against increases in interest rates, which might lead to higher interest costs for the Company or its joint venture.

The Company has entered into and settled positions in various exchange and non-exchange traded commodity swap, option and future contracts. In the Company’s commodity trading and logistics business, fixed price future purchase and sale contracts of ethanol and sugar are included in the Company’s non-exchange traded derivative positions. The Company enters into exchange traded positions to protect these purchase and sales contracts as well as its inventory balances from market changes. As of December 31, 2010, the net market exposure to ethanol and sugar under these positions was not material. The Company also enters into exchange traded positions (primarily natural gas, crude oil, gasoline, ethanol and sugar) to provide value to the Company should there be a sustained decline in the price of commodities that could lead to a reduction in the market values and cash flows of the Company’s offshore marine and inland river businesses. As of December 31, 2010, these positions were not material.

The Company has entered into and settled various positions in U.S. treasury notes and bonds through rate locks, futures or options on futures tied to U.S. treasury notes. The general purpose of these transactions is to

117

provide value to the Company should the price of U.S. treasury notes and bonds decline, leading to generally higher interest rates, which might lead to higher interest costs for the Company. As of December 31, 2010, these positions consisted primarily of treasury futures with a notional value of $50.0 million and a one-year rate-lock agreement with a notional value of $100.0 million. The treasury rate lock agreement provides for a net cash settlement in October 2011 based on the then current ten-year U.S. Treasury Note versus the agreement rate of 2.845%.

4. ACQUISITIONS AND DISPOSITIONS

SES Kazakhstan Acquisition. On August 31, 2010, the Company obtained a 100% controlling interest in SES Borkit LLP through its acquisition of its partners’ interest for $1.0 million (cash of $0.6 million and contingent consideration of $0.4 million). Upon acquisition, SES-Borkit LLP was renamed SES-Kazakhstan LLP (“SES-Kazakhstan”). The selling partner has the opportunity to receive additional consideration of up to $0.4 million based on certain performance measures over the period from the date of acquisition through August 2013. As a consequence of the acquisition of a controlling interest, the Company adjusted its investment in SES-Kazakhstan to fair value resulting in the recognition of a $0.5 million gain, net of tax, which is included in equity in earnings of 50% or less owned companies. Following the change in control, the Company consolidated SES-Kazakhstan’s financial position and results of its operations. The Company performed a preliminary fair value analysis and the purchase price was allocated to the acquired assets and liabilities based on their fair values resulting in no goodwill being recorded. The preliminary fair value analysis is pending completion of a final valuation for the acquired assets and liabilities.

SEASPRAIE Acquisition. On July 31, 2010, the Company obtained a 100% controlling interest in Seaspraie Holdings LLC (“Seaspraie”) through the redemption of its partner’s interest by distributing financial assets and equipment totaling $56.1 million from the joint venture.

The Company performed a fair value analysis and the purchase price was allocated to the acquired assets and liabilities based on their fair values resulting in $1.0 million of goodwill being recorded. The fair value analysis was finalized in December 2010. The selling stockholders of PIER have the opportunity to receive additional consideration of up to $1.3 million based upon certain performance measures over the period from the date of acquisition through May 2011. During the year ended December 31, 2010, the Company paid $0.2 million of additional consideration in accordance with the acquisition agreement and reduced its accrued contingent liability.

CBK Acquisition. On December 1, 2009, the Company acquired all of the assets of CBK, Inc., a liquid cargo servicing company, for $0.5 million in cash ($0.3 million in 2009 and $0.2 million in 2010).

As a result, the future profits recognized from these two tankers will consist entirely of the amortization of the deferred gains of $69.3 million. The selling subsidiaries’ ability to meet their obligations under the leasebacks is dependent upon the offsetting bareboat charter-out arrangements with the customer.

The Company also sold 40 dry cargo barges to one of the Company’s 50% or less owned companies for $19.8 million, in the aggregate (see Note 5).

For nonqualified withdrawals, the Company is obligated to pay taxes on the previously deferred gains at the prevailing statutory tax rate plus a 1.1% penalty tax and interest thereon for the period such taxes were deferred.

Consideration of $13.5 million, including Common Stock valued at $11.5 million and $2.0 million in cash, was allocated to the purchase of the conversion option embedded in the Convertible Debentures as included in the accompanying consolidated statements of changes in equity.

5.875% Senior Notes. In 2002, SEACOR sold $200.0 million aggregate principal amount of its 5.875% Senior Notes due October 1, 2012 (the “5.875% Senior Notes”). The 5.875% Senior Notes were issued under a supplemental indenture dated as of September 27, 2002 (the “2002 Supplemental Indenture”) to the base indenture relating to SEACOR’s senior debt securities, dated as of January 10, 2001, between SEACOR and U.S. Bank National Association, as trustee. Interest on the 5.875% Senior Notes is payable semi-annually on April 1 and October 1 of each year. The 5.875% Senior Notes may be redeemed at any time, in whole or in part, at a price equal to 100% of the principal amount, plus accrued and unpaid interest to the date of redemption, plus a specified “make-whole” premium. The 2002 Supplemental Indenture contained covenants including, among others, limitations on liens and sale and leasebacks of certain Principal Properties, as defined, and certain restrictions on SEACOR consolidating with or merging into any other Person, as defined. During the year ended December 31, 2010, the Company purchased $2.4 million, in principal amount, of its 5.875% Senior Notes for $2.5 million resulting in a loss on debt extinguishment of $0.1 million. During the year ended December 31, 2009, the Company purchased $18.4 million, principal amount, of its 5.875% Senior Notes at a price of 100 percent of par without a material gain or loss.

Title XI Bonds. Five double-hull product and chemical tankers (the “Title XI tankers”) owned by subsidiaries of the Company (the “Title XI companies”) were financed through the issuance of U.S. Government Guaranteed Ship Financing Bonds (the “Title XI Bonds” or “Title XI financing”). Seven series of bonds comprise the Title XI Bonds bearing interest at rates ranging from 6.50% to 7.54% with semi-annual principal and interest payments and maturing through June 2024. During the year ended December 31, 2010, the Company redeemed all of the outstanding bonds on two of the Company’s double hull product tankers, in principal amount of $61.9 million, for an aggregate purchase price of $63.0 million, including a make-whole premium, resulting in a loss on debt extinguishment of $0.2 million. Following the redemption, three series of bonds remained outstanding each with an interest rate of 6.50%.

A percentage of earnings attributable to each of the Title XI tankers’ operations is required to be deposited into Title XI reserve fund bank accounts. Cash held in these accounts is invested as prescribed by Title XI financing agreements. Withdrawals from these accounts are permitted for limited purposes, subject to the prior approval of the U.S. Maritime Administration. As of December 31, 2010 and 2009, the Title XI reserve fund account balances were $9.6 million and $16.6 million, respectively. During the year ended December 31, 2010, $7.0 million of Title XI reserve funds were released following the redemption of the bonds, as described above.

The Title XI financing agreements contain covenants restricting cash distributions subject to certain financial tests. Failure to meet these financial tests, among other things, restricts Title XI companies from (1) distributing capital; (2) paying dividends; (3) increasing employee compensation and paying other indebtedness; (4) incurring additional indebtedness; (5) making investments and (6) acquiring fixed assets. Cash distributions (as defined in the Title XI financing agreements) from a Title XI company are prohibited until such company achieves certain levels of working capital. As of December 31, 2010 and 2009, the Title XI companies held $12.7 million and $34.0 million in restricted cash that was limited in use for the operation of the tankers and cannot be used to fund the Company’s general working capital requirements.

In the event of default (as defined in the Title XI financing agreements), all of the Title XI tankers, in addition to the assignment of earnings relating to those vessels and the funds on deposit in the Title XI reserve fund accounts, serve as collateral for the repayment of the Title XI Bonds. The aggregate net book value as of December 31, 2010 of the Title XI tankers was $155.4 million.

Revolving Credit Facility. The Company has a $450.0 million unsecured revolving credit facility that matures in November 2013. Advances under the facility are available for general corporate purposes. This facility will be reduced by 10% of the maximum committed amount during its term at the beginning of each of the final two years of the credit agreement. Interest on advances will be charged at a rate per annum of LIBOR plus an applicable margin of 60 basis points through November 2011 and 67.5 basis points thereafter. A quarterly commitment fee is payable based on the average unfunded portion of the committed amount at the rate of 17.5 basis points through November 2011 and at the rate of 22.5 basis points thereafter. The revolving credit facility contains various restrictive covenants including interest coverage, secured debt to total capitalization, funded debt to total capitalization ratios, as well as other customary covenants, representations and warranties, funding conditions and events of default, including a cross-default as defined in the credit agreement. As of December 31, 2010, the Company had $125.0 million outstanding borrowings under the revolving credit facility and the remaining availability under this facility was $323.5 million, net of issued letters of credit of $1.5 million.

These obligations have maturities ranging from several days through May 2021 and, as of December 31, 2010, have interest rates ranging from 3.0% to 8.5%, and require periodic payments of interest and principal. During the years ended December 31, 2010, 2009 and 2008 proceeds from the issuance of other debt was $38.7 million, $52.2 million and $11.8 million, respectively and repayments on other debt was $4.9 million, $40.5 million and $3.1 million for the years December 31, 2010, 2009 and 2008, respectively.

The Compensation Committee of SEACOR’s Board of Directors elected, at its discretion, to pay the dividend on the restricted share awards in December 2010 rather than depositing amounts in escrow pending the lapsing of restrictions.

11. SAVINGS PLANS

SEACOR Savings Plan. The Company provides a defined contribution plan to its employees (the “Savings Plan”). The Company’s contribution to the Savings Plan is limited to 50% of an employee’s first 6% of wages invested in the Savings Plan and is subject to annual review by the Board of Directors of SEACOR. The Company’s Savings Plan costs were $3.0 million, $3.1 million and $3.2 million for the years ended December 31, 2010, 2009 and 2008, respectively.

SEACOR Deferred Compensation Plan. In 2005, the Company established a non-qualified deferred compensation plan (the “Deferred Compensation Plan”) to provide a select group of highly compensated employees, as well as non-employee directors, with the ability to defer receipt of up to 75% of their cash base salary, up to 100% of their cash bonus and up to 100% of their vested restricted stock (deferred in the form of Restricted Stock Units, as defined in the plan) for each fiscal year. Each participant’s compensation deferrals are credited to a bookkeeping account and, subject to certain restrictions, each participant may elect to have their cash deferrals in such account indexed against one or more investment options, solely for purposes of determining amounts payable under the Deferred Compensation Plan (the Company is not obligated to actually invest any deferred amounts in the selected investment options).

Participants may receive a distribution of deferred amounts, plus any earnings thereon (or less any losses), on a date specified by the participant or, if earlier, upon a separation from service or upon a change of control. All distributions to participants following a separation from service shall be in the form of a lump sum, except if such separation qualifies as “retirement” under the terms of the plan, in which case it may be paid in installments if previously elected by the participant. Distributions to “Key Employees” upon a separation from service (other than due to death) will not commence until at least 6 months after the separation from service. Participants are always 100% vested in the amounts that participants contribute to their Deferred Compensation Plan accounts. The Company, at its option, may contribute amounts to participants’ accounts, which may be subject to vesting requirements.

The obligations of the Company to pay deferred compensation under the Deferred Compensation Plan are general unsecured obligations of the Company and rank equally with other unsecured indebtedness of the Company that is outstanding from time to time. As of December 31, 2010 and 2009, the Company had an obligation of $2.7 million and $3.5 million, respectively, related to the Deferred Compensation Plan and is included in the accompanying consolidated balance sheets as deferred gains and other liabilities. The total amount of the Company’s obligation under the Deferred Compensation Plan will vary depending upon the level of participation by participants and the amount of compensation that participants elect to defer under the plan. The duration of the Deferred Compensation Plan is indefinite (subject to the Board of Directors’ discretion to amend or terminate the plan).

12. SHARE BASED COMPENSATION

Share Incentive Plans. SEACOR’s stockholders approved the 2007 Share Incentive Plan to provide for the grant of options to purchase shares of Common Stock, stock appreciation rights, restricted stock, stock awards, performance awards and restricted stock units to non-employee directors, key officers and employees of the Company. The 2007 Share Incentive Plan superseded the 1992 Non-Qualified Stock Option Plan, the 1996 Share Incentive Plan, the 2003 Non-Employee Director Share Incentive Plan and the 2003 Share Incentive Plan (collectively, the “Share Incentive Plans”). The Compensation Committee of the Board of Directors administers the Share Incentive Plans. A total of 4,650,000 shares of Common Stock have been authorized for grant under the Share Incentive Plans. All shares issued pursuant to such grants are newly issued shares of Common Stock. The exercise price per share of options granted cannot be less than 100% of the fair market value of Common Stock at the date of grant under the Share Incentive Plans. Grants to date have been limited to stock awards, restricted stock, restricted stock units and options to purchase shares of Common Stock.

Restricted stock and restricted stock units typically vest from one to five years after grant and options to purchase shares of Common Stock typically vest and become exercisable from one to five years after date of grant. Options to purchase shares of Common Stock granted under the Share Incentive Plans expire no later than the tenth anniversary of the date of grant. In the event of a participant’s death, retirement, termination by the Company without cause or a change in control of the Company, as defined in the Share Incentive Plans, restricted stock and restricted stock units vest immediately and options to purchase shares of Common Stock vest and become immediately exercisable.

Employee Stock Purchase Plans. SEACOR’s stockholders approved the 2009 Employee Stock Purchase Plan and the 2000 Employee Stock Purchase Plan (collectively, the “Employee Stock Purchase Plans”) to permit the Company to offer Common Stock for purchase by eligible employees at a price equal to 85% of the lesser of (i) the fair market value of Common Stock on the first day of the offering period or (ii) the fair market value of Common Stock on the last day of the offering period. Common Stock is made available for purchase under the Employee Stock Purchase Plans for six-month offering periods. The Employee Stock Purchase Plans are intended to comply with Section 423 of the Internal Revenue Code of 1986, as amended (the “Code”), but is not intended to be subject to Section 401(a) of the Code or the Employee Retirement Income Security Act of 1974. The Board of Directors of SEACOR may amend or terminate the Employee Stock Purchase Plans at any time; however, no increase in the number of shares of Common Stock reserved for issuance under the Employee Stock Purchase Plans may be made without stockholder approval. A total of 600,000 shares of Common Stock have been approved for purchase under the Employee Stock Purchase Plans with all shares issued from those held in treasury. Each of the Employee Stock Purchase Plans has a term of ten years.

Mr. Fabrikant and his affiliates were participants in the barge pools prior to the acquisition of SCF Marine Inc. by SEACOR in 2000. In the years ended December 31, 2010, 2009 and 2008, Mr. Fabrikant and his affiliates earned $1.1 million, $1.0 million and $1.7 million, respectively, of net barge pool results (after payment of $0.1 million, $0.1 million and $0.1 million, respectively, in management fees to the Company). As of December 31, 2010, 2009 and 2008, the Company owed Mr. Fabrikant and his affiliates $0.5 million, $0.4 million and $0.7 million, respectively, for undistributed net barge pool results. Mr. Fabrikant and his affiliates participate in the barge pools on the same terms and conditions as other pool participants who are unrelated to the Company.

During the year ended December 31, 2008, the Company purchased a barge from Mr. Fabrikant’s sister for $0.5 million and sold it to Inland River Services’ South American joint venture. The proceeds received by Mr. Fabrikant’s sister were deposited into a construction reserve fund established by her that is managed by the Company. During the year ended December 31, 2008, the Company, on behalf of Mr. Fabrikant, sold three barges owned by him for scrap, for $0.3 million.

Mr. Fabrikant is also a director of Diamond Offshore Drilling, Inc. (“Diamond”), which is also a customer of the Company. The total amount earned from business conducted with Diamond did not exceed $5.0 million in any of the years ended December 31, 2010, 2009 or 2008.

14. COMMITMENTS AND CONTINGENCIES

The Company’s unfunded capital commitments as of December 31, 2010 consisted primarily of offshore support vessels, helicopters, an interest in a dry-bulk articulated tug-barge, inland river dry cargo barges and other equipment. These commitments totaled $254.3 million, of which $169.9 million is payable during 2011 and the balance payable through 2013. Subsequent to December 31, 2010, the Company committed to purchase additional equipment for $10.8 million.

During 2006 and 2007, Marine Transportation Services (“MTS”) had two of its tankers retrofitted to a double-hull configuration in a foreign shipyard to enable each of them to continue to transport crude oil and petroleum products beyond their OPA 90 mandated retirement dates in 2011. Both vessels operate in the U.S. coastwise trade that, under the Shipping Acts, is restricted to vessels built or rebuilt in the United States. In May 2005, MTS received a determination from the U.S. Coast Guard (“USCG”), which administers the United States build requirements of the Shipping Acts, concluding the retrofit work would not constitute a foreign rebuilding and therefore would not jeopardize the tankers’ eligibility to operate in the U.S. coastwise trade. MTS completed the retrofit work in the foreign shipyard in reliance upon the USCG’s determination, which MTS believes was correct and in accord with the USCG’s long-standing regulations and interpretations. On July 9, 2007, a U.S. shipbuilders trade association and two operators of tankers in the U.S. coastwise trade (“Shipbuilders”) commenced a civil action in the U.S. District Court for the Eastern District of Virginia, Shipbuilders Council of America, Inc., et al. v. U.S. Department of Homeland Security, et al., No. 1:07cv665 (E.D. Va.) (the “SB Trader Litigation”), in which they sought to have the court set aside the USCG’s determination and direct the USCG to revoke the coastwise license of one of the two retrofitted tankers, the Seabulk Trader. MTS intervened in the action to assist the USCG in defending its determination. On April 24, 2008, the Court issued a Memorandum Opinion granting a motion for summary judgment by Shipbuilders setting aside the USCG’s determination and remanding the matter to the USCG for further proceedings with instructions to revoke the coastwise endorsement of the Seabulk Trader. On April 30, 2008, MTS appealed the decision to the U.S. Court of Appeals for the Fourth

136

Circuit (the “Court of Appeals”), and the lower court’s decision was stayed pending appeal, subject to certain terms (which MTS also separately appealed). Those terms required that MTS pay to the plaintiffs 12.5% of the revenue generated by the Seabulk Trader from November 7, 2008 in the event that the Court of Appeals affirms the lower court’s decision to revoke its coastwise endorsement (the “Undertaking”). On July 2, 2008, Shipbuilders commenced a second civil action in the U.S. District Court for the Eastern District of Virginia, entitled Shipbuilders Council of America, Inc., et al. v. U.S. Department of Homeland Security, et al., No. 1:08cv680 (E.D. Va.) (the “SB Challenge Litigation”), alleging essentially identical claims as those asserted in the SB Trader Litigation against MTS’s second retrofitted tanker, the Seabulk Challenge. MTS has intervened in the SB Challenge Litigation that was stayed pending the decision of the Court of Appeals in the SB Trader Litigation. In September 2009, the Court of Appeals reversed the District Court, holding that the USCG’s interpretation was correct and that the District Court erred in requiring MTS to provide the Undertaking. On January 19, 2010, the District Court vacated its April 24, 2008 Order to the extent it directed the USCG to revoke the coastwise endorsement for the Seabulk Trader and remanded the matter to the USCG with instructions to (i) provide a fuller explanation of one aspect of its rebuild decision and (ii) consider further whether certain work relating to the vessel’s segregated ballast tanks constituted a prohibited foreign installation of required segregated ballast tanks. On August 31, 2010, the USCG issued a further determination further explaining its rebuild decision and concluding that the work relating to the vessel’s segregated ballast tanks did not constitute the installation of a required segregated ballast tank. One of the three plaintiffs in the District Court litigation urged the USCG to reach a contrary result with respect to the segregated ballast work, and it is possible that the plaintiff will ask the District Court to set aside this aspect of the USCG’s decision as well. The loss of coastwise eligibility for its two retrofitted tankers could lead to impairment concerns and could adversely affect the Company’s financial condition and its results of operations. The aggregate carrying value of the Company’s two retrofitted tankers was $46.0 million as of December 31, 2010 and such tankers contributed operating revenues of $19.8 million during the year ended December 31, 2010.

Certain subsidiaries of the Company are participating employers in an industry-wide, multi-employer, defined benefit pension fund, the United Kingdom Merchant Navy Officers Pension Fund (“MNOPF”). Under the direction of a court order, any deficit of the MNOPF is to be remedied through funding contributions from all participating employers. The Company’s participation relates to officers employed between 1978 and 2002 by SEACOR’s Stirling group of companies (which had been acquired by SEACOR in 2001) and its predecessors. Based on an actuarial valuation of the MNOPF in 2003, the Company was invoiced and expensed $4.4 million in 2005, representing the Company’s allocated share of a total funding deficit of $412.0 million. Subsequent to this invoice, the pension fund trustees determined that $49.0 million of the $412.0 million deficit was deemed uncollectible due to the non-existence or liquidation of certain participating employers and the Company was invoiced and expensed $0.6 million in 2007 for its allocated share of the uncollectible deficit. Based on an actuarial valuation of the MNOPF in 2006, the Company was invoiced and expensed $3.9 million in 2007, representing the Company’s allocated share of an additional funding deficit of $332.6 million. Based on an actuarial valuation of the MNOPF in 2009, the Company was invoiced and expensed $7.8 million in 2010, representing the Company’s allocated share of an additional funding deficit of $636.9 million. Depending on the results of future actuarial valuations, it is possible that the MNOPF will experience further funding deficits, requiring the Company to recognize payroll related operating expenses in the periods invoices are received.

A subsidiary of the Company is a participating employer in an industry-wide, multi-employer, defined benefit pension fund, the United Kingdom Merchant Navy Ratings Pension Fund (“MNRPF”). The Company’s participation relates to ratings employed between 1978 and 2001 by SEACOR’s Stirling group of companies (which had been acquired by SEACOR in 2001) and its predecessors. Based on an actuarial valuation in March 2008, the MNRPF has an accumulated funding deficit of $320.9 million (£203.0 million). No decision has yet been reached as to how the deficit will be recovered, but the Company expects it is likely that participating employers will be invoiced for their allocated share, at which time the Company would recognize payroll related operating expenses. The Company estimates its allocated share of the uninvoiced deficit to be approximately $1.1 million (£0.7 million). Depending on the results of the most recent and future actuarial valuations, it is possible that the MNRPF will experience further funding deficits, requiring the Company to recognize payroll related operating expenses in the periods invoices are received.

On June 12, 2009, a purported civil class action was filed against SEACOR, Era Group Inc., Era Aviation, Inc., Era Helicopters LLC and two other defendants (collectively the “Defendants”) in the U.S. District Court for the District of Delaware, Superior Offshore International, Inc. v. Bristow Group Inc., et al., No. 09-CV-438 (D.Del.). SEACOR acquired Era Group Inc., Era Aviation, Inc., and Era Helicopters LLC in December 2004. The complaint alleges that the Defendants violated federal antitrust laws by conspiring with each other to raise, fix, maintain or stabilize prices for offshore helicopter services in the U.S. Gulf of Mexico during the period January 2001 to December 2005. The purported class of plaintiffs includes all direct purchasers of such services and the relief sought includes compensatory damages and treble damages. On September 14, 2010, the District Court entered an order dismissing the complaint. On November 30, 2010, the District Court granted the plaintiffs motion for reconsideration and amendment (the “Motions”), and ordered limited discovery strictly in regard to the allegations set forth on the plaintiff’s amended complaint. The limited discovery was completed and the defendants have filed a motion for summary judgment, which is pending. The Company is unable to estimate the potential exposure, if any, resulting from these claims but believes they are without merit and intends to vigorously defend the action.

On July 14, 2010, a group of individuals and entities purporting to represent a class commenced a civil action in the U.S. District Court for the Eastern District of Louisiana, Terry G. Robin, et al. v. Seacor Marine, L.L.C., et al., No. 2:10-cv-01986 (E.D. La.), in which they assert that support vessels, including vessels owned by the Company, responding to the explosion and resulting fire that occurred aboard the semi-submersible drilling rig, the Deepwater Horizon, were negligent in their efforts to save lives and put out the fire and contributed to the sinking of the Deepwater Horizon and subsequent oil spill. The action now is part of the overall multi-district litigation, In re Oil Spill by the Oil Rig “Deepwater Horizon”, MDL No. 2179. The complaint seeks compensatory, punitive, exemplary, and other damages. The Company believes that this lawsuit brought by class action lawyers targeting emergency responders acting under the direction of the U.S. Coast Guard has no merit and will seek its dismissal. The Company also recently filed petitions seeking exoneration from or limitation of liability in relation to any actions that may have been taken by vessels owned by the Company to extinguish the fire. Pursuant to the Limitation of Liability Act, those petitions impose an automatic stay on the Robin case, and the court has set a deadline of April 20, 2011 for individual claimants to assert claims in the limitation cases.

On July 20, 2010, two individuals purporting to represent a class commenced a civil action in the Civil District Court for the Parish of Orleans in the State of Louisiana, John Wunstell, Jr. and Kelly Blanchard v. BP, et al., No. 2010-7437 (Division K) (the “Wunstell Action”), in which they assert, among other theories, that Mr. Wunstell suffered injuries as a result of his exposure to certain noxious fumes and chemicals in connection with the provision of remediation, containment and response services by O’Brien’s Response Management Inc. (“O’Brien’s), a subsidiary of SEACOR. The action now is part of the overall multi-district litigation, In re Oil Spill by the Oil Rig “Deepwater Horizon”, MDL No. 2179. The complaint also seeks to establish a “class-wide court-supervised medical monitoring program” for all individuals “participating in BP’s Deepwater Horizon Vessels of Opportunity Program and/or Horizon Response Program” who allegedly experience injuries similar to Mr. Wunstell. The Company believes this lawsuit has no merit and will seek its dismissal. Pursuant to contractual agreements with the responsible party, the responsible party has agreed, subject to certain potential limitations, to indemnify and defend O’Brien’s in connection with the Wunstell Action and claims asserted in the MDL.

On December 15, 2010, SEACOR subsidiaries O’Brien’s and National Response Corporation (“NRC”) were named as defendants in one of the several consolidated “master complaints” that have been filed in the overall multi-district litigation, In re Oil Spill by the Oil Rig “Deepwater Horizon”, MDL No. 2179. The master complaint naming O’Brien’s and NRC asserts various claims on behalf of a punitive class against multiple defendants concerning the clean-up activities generally, and the use of dispersants specifically. By court order the Wunstell Action has been stayed as a result of the filing of the referenced master complaint. The Company believes that the claims asserted against its subsidiaries in the master complaint have no merit and will seek dismissal of the master complaint against both O’Brien’s and NRC. In addition to the indemnity provided to O’Brien’s, the Company has also sought indemnity from the responsible party, pursuant to certain contractual arrangements for the claims asserted against NRC in the MDL.

138

In the normal course of its business, the Company becomes involved in various other litigation matters including, among other things, claims by third parties for alleged property damages and personal injuries. Management has used estimates in determining the Company’s potential exposure to these matters and has recorded reserves in its financial statements related thereto where appropriate. It is possible that a change in the Company’s estimates of that exposure could occur, but the Company does not expect such changes in estimated costs would have a material effect on the Company’s consolidated financial position or its results of operations.

During the year ended December 31, 2010, the Company received notice from the IRS of $12.6 million in proposed penalties regarding Marine Transportation Services’ informational excise tax filings for prior years. The Company intends to vigorously defend its position that the proposed penalties are erroneous and believes the resolution of this matter will not have a material effect on the Company’s consolidated financial position or its results of operations.

As of December 31, 2010, the Company leases 21 offshore support vessels, eleven helicopters, four barges, two tankers, one harbor tug and certain facilities and other equipment. These leasing agreements have been classified as operating leases for financial reporting purposes and related rental fees are charged to expense over the lease terms. The leases generally contain purchase and lease renewal options or rights of first refusal with respect to the sale or lease of the equipment. The lease terms of the tankers, which are subject to subleases, have durations of 143 and 158 months. The lease terms of the other equipment range in duration from one to seven years. Certain of the equipment leases are the result of sale-leaseback transactions with finance companies (see Note 4) and certain of the gains arising from such sale-leaseback transactions have been deferred in the accompanying consolidated balance sheets and are being amortized as reductions in rental expense over the lease terms (see Note 1).

Total rental expense for the Company’s operating leases in 2010, 2009 and 2008 was $56.0 million, $65.5 million and $66.4 million, respectively. Future minimum payments in the years ended December 31 under operating leases that have a remaining term in excess of one year as of December 31, 2010 were as follows (in thousands):

	Total Minimum Payments		Non-cancellable Subleases(1)			Net Minimum Payments
2011	$	46,676	$	(17,345	)	$	29,331
2012		39,717		(17,393	)		22,324
2013		26,062		(17,345	)		8,717
2014		24,580		(17,345	)		7,235
2015		22,647		(17,345	)		5,302
Years subsequent to 2015		135,434		(128,114	)		7,320

(1) The total minimum offsetting payments to be received under existing long-term bareboat charter-out arrangements (see Note 4).

15. MAJOR CUSTOMERS AND SEGMENT INFORMATION

Accounting standards require public business enterprises to report information about each of their operating business segments that exceed certain quantitative thresholds or meet certain other reporting requirements. Operating business segments have been defined as a component of an enterprise about which separate financial information is available and is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company has identified the following reporting segments:

Offshore Marine Services. Offshore Marine Services operates a diversified fleet of support vessels primarily servicing offshore oil and gas exploration, development and production facilities worldwide. Vessels in this service are employed to deliver cargo and personnel to offshore installations, handle anchors for drilling rigs and other marine equipment, support offshore construction and maintenance work, provide standby safety

139

support and emergency response services. From time to time, Offshore Marine Services supports projects such as well stimulation, seismic data gathering and offshore accommodation. Offshore Marine Services also offers logistics services in support of offshore oil and gas exploration, development and production operations, including shorebased, marine transport and other supply chain management services. This segment contributed 19%, 33% and 43% of consolidated operating revenues in 2010, 2009 and 2008, respectively.

Aviation Services. Aviation Services is primarily engaged in transportation services to the offshore oil and gas exploration, development and production industry, aircraft leasing, transportation services to hospitals, and flightseeing tours in Alaska. In addition, Aviation Services sells fuel and provides other services to corporate aircraft at its fixed base operation at Ted Stevens Anchorage International Airport. It also provides aircraft and flight crews under contracts, provides flight training services and manages customer-owned aircraft. Aviation Services operates a FAA approved maintenance repair station in Lake Charles, LA. Aviation Services contributed 9%, 14% and 15% of consolidated operating revenues in 2010, 2009 and 2008, respectively.

Inland River Services. Inland River Services owns, operates, invests in and markets inland river transportation equipment. The Company believes it operates one of the industry’s newest fleets of dry cargo and liquid tank barges transporting agricultural, industrial, chemical and petrochemical products on the U.S. Inland River Waterways, primarily the Mississippi River, Illinois River, Tennessee River, Ohio River and their tributaries and the Gulf Intracoastal Waterways. Inland River Services also owns towboats used for moving barges, fleeting operations used in barge loading and unloading activities, and deck barges for specialized projects. It also manages barges for third parties. Inland River Services contributed 6%, 9% and 9% of consolidated operating revenues in 2010, 2009 and 2008, respectively.

Marine Transportation Services. Marine Transportation Services operates a fleet of U.S.-flag product tankers, providing marine transportation services for petroleum products and chemicals moving in the U.S. domestic coastwise trade. This segment contributed 3%, 5% and 7% of consolidated operating revenues in 2010, 2009 and 2008, respectively.

Environmental Services. Environmental Services primarily provides emergency preparedness and response services to oil, chemical, industrial and marine transportation clients, and government agencies in the United States and abroad. In the United States, these services are generally rendered to those clients who store, transport, produce or handle petroleum and certain non-petroleum oils that are subject to the provisions of OPA 90 and various other federal, state and municipal regulations. Internationally, these services may be required by legislation and regulation of countries, international maritime conventions and environmental covenants placed on clients by their lending institutions. To a lesser extent, Environmental Services provides emergency preparedness and response services to governmental agencies arising from natural disasters and homeland security issues such as debris removal monitoring, public assistance projects, bio-terrorism, pandemic influenza and port security. Environmental Services also provides other services to oil, chemical, industrial and government clients including hazardous waste management, industrial and marine cleaning, salvage support, petroleum storage tank removal, pipeline repair and site remediation services. Business is conducted primarily through the Company’s wholly owned subsidiaries: National Response Corporation (“NRC”), O’Brien’s Response Management Inc. and SEACOR Environmental Services International Limited. Environmental Services contributed 33%, 8% and 10% of consolidated operating revenues in 2010, 2009 and 2008, respectively.

Commodity Trading and Logistics. Commodity Trading and Logistics operates an integrated business involved in the purchase, storage, transportation and sale of agricultural and energy commodities. The principal commodities currently involved are rice, sugar, ethanol and clean blendstocks. Commodity Trading and Logistics contributed 28%, 28% and 13% of consolidated operating revenues in 2010, 2009 and 2008, respectively.

Other Activities.

Harbor and Offshore Towing Services. As of December 31, 2010, Harbor and Offshore Towing Services operated a total of five ocean liquid tank barges and 30 vessels, of which 15 were conventional tugs, five were

140

Azimuth Stern Drive tugs, three were Forward Azimuth Drive tugs, three were tractor tugs and four were Ship Docking Modules (“SDM™”). SDMs™ are innovative vessels designed and patented by the Company that are maneuverable, efficient and flexible and require fewer crew members than conventional harbor tugs.

Other Joint Ventures, Leasing and Other Activities. The Company has investments in 50% or less owned companies which include a company that designs and manufactures water treatment systems for sale or lease, and three industrial aviation services businesses in Asia. The Company also engages in lending and leasing activities.

In 2010, one customer (BP p.l.c.) was responsible for $871.4 million, or 33%, of consolidated operating revenues. In 2009 and 2008, the Company did not earn revenues that were greater than or equal to 10% of total revenues from a single customer. For the years ended December 31, 2010, 2009 and 2008, approximately 16%, 30% and 32%, respectively, of the Company’s operating revenues were derived from its foreign operations. The Company’s foreign revenues are primarily derived from its Offshore Marine Services fleet. These vessels are highly mobile and regularly and routinely move between countries within a geographical region of the world. In addition, these vessels may be redeployed among the geographical regions as changes in market conditions dictate. Because of this asset mobility, revenues and long-lived assets, primarily property and equipment, in any one country are not considered material.

PURSUANT TO THE SEACOR HOLDINGS INC.

AMENDED 2007 SHARE INCENTIVE PLAN

RESTRICTED STOCK GRANT AGREEMENT (the “Agreement”), dated as of                             , between SEACOR Holdings Inc., a Delaware corporation (the “Company”), and                              (the “Grantee”).

W I T N E S S E T H :

WHEREAS, Grantee is an officer or key employee of the Company or one or more subsidiaries or affiliates of the Company; and

WHEREAS, the Company desires to issue and grant to the Grantee, and the Grantee desires to accept, shares of the Company’s common stock, $0.01 par value (“Common Shares”), upon the terms and subject to the conditions herein set forth;

NOW, THEREFORE, in consideration of the premises and the mutual covenants herein contained, the parties hereto, intending to be legally bound, hereby agree as follows:

1. Grant of Restricted Stock. In recognition of the Grantee’s commitment to the continued growth and financial success of the Company, the Company hereby grants to the Grantee                      (restricted) Common Shares (the “Restricted Stock”). Except as otherwise provided herein including, without limitation, the provisions of Paragraph 5 hereof, the Grantee shall have with respect to the Restricted Stock all of the rights of a holder of Common Shares, including the rights to receive dividends, if paid, and the right to vote the Common Shares, provided, however, that, prior to the record date for any dividend, the Committee shall determine, in its sole discretion, whether (i) the Grantee shall immediately receive the dividend on the Restricted Stock on the payment date, notwithstanding the vesting date of the underlying Restricted Stock as set forth in Section 3 below or (ii) the amount of the dividend otherwise payable on the Restricted Stock shall be held in escrow from and after the dividend payment date until the Restricted Stock vests, at which time the amount of the dividend shall be paid to the Grantee. Simultaneously with the execution and delivery of this Agreement by the parties hereto, the Company shall deliver to the Grantee a stock certificate (or certificates) representing the shares of the Restricted Stock, which certificate(s) shall (a) be registered on the Company’s stock transfer books in the name of the Grantee and (b) bear (in addition to any other legends required by applicable law) the following legend (or a legend substantially similar thereto):

“This certificate and the shares represented hereby are subject to, and shall be transferable only in accordance with, the provisions of a certain Restricted Stock Grant Agreement dated                              between                              and SEACOR Holdings Inc.”

2. Removal of Restricted Stock Legend. After shares of the Restricted Stock issued to the Grantee hereunder have become vested in accordance with provisions of this Agreement, promptly upon delivery of stock certificates representing such vested shares have been delivered by the Grantee to the Company together with a written request therefor, the Company shall cause the transfer agent for the Common Shares to issue separate certificates representing a) the Common Shares that are free of the restrictions set forth herein and without the legend referred to in Paragraph 1 hereof and b) the remaining unvested Common Shares bearing the legend referred to in Paragraph 1 hereof.

3. Vesting.

A. Subject to the terms and conditions set forth herein, including, without limitation, the provisions of Paragraph 5 hereof, beneficial ownership without the restrictions set forth in Paragraph 1 hereof (“Beneficial Ownership”) of the restricted stock shall vest in the Grantee as follows and in the respective dates herein set forth (each such date, or “Vesting Date”):

DATE NUMBER OF SHARES

Notwithstanding the foregoing, Beneficial Ownership of all of the aforementioned shares of Restricted Stock shall vest immediately, without any action on the part of the Company (or its successor as applicable) or the Grantee if, prior to a Forfeiture hereinafter (as defined) by the Grantee pursuant to Paragraph 5 hereof, any of the following events occur:

(i) the death of the Grantee;

(ii) the Retirement (as hereinafter defined) of the Grantee;

(iii) the termination of the Grantee’s employment with the Company and/or its subsidiaries, as applicable, by the Company (or applicable subsidiaries) without Cause (as hereinafter defined); and

(iv) the occurrence of a Change-in-Control of the Company (as hereinafter defined).

B. As used in this Agreement, the following terms shall have the following respective meanings:

“Retirement” shall mean Grantee’s formal retirement from employment with the Company under acceptable circumstances as determined by the Committee in its sole discretion (which determination may be conditioned upon, among other things, the Grantee entering into a non-competition agreement with the Company).

“Cause” shall mean (i) fraud, embezzlement or gross insubordination on the part of the Grantee or breach by the Grantee of his or her obligations under any Company policy or procedure; (ii) conviction of or the entry of a plea of nolo contendere by the Grantee for any felony; (iii) a material breach of, or the willful failure or refusal by the Grantee to perform and discharge, his or her duties, responsibilities or obligations, as a Grantee; or (iv) any act of moral turpitude or willful misconduct by the Grantee which (A) is intended to result in substantial personal enrichment of the Grantee at the expense of the Company or any of its subsidiaries or affiliates or (B) has a material adverse impact on the business or reputation of the Company, or any of its subsidiaries or affiliates.

“Change-in-Control” of the Company shall be deemed to have occurred upon any of the following events:

(i) a change in control of the direction and administration of the Company’s business of a nature that would be required to be reported in response to Item 6(e) of Schedule 14A of Regulation 14A promulgated under the Exchange Act; or

(ii) during any period of two (2) consecutive years, the individuals who at the beginning of such period constitute the Company’s Board of Directors or any individuals who would be “Continuing Directors” (as hereinafter defined) cease for any reason to constitute at least a majority thereof; or

(iii) the Company’s Common Stock shall cease to be publicly traded; or

(iv) the Company’s Board of Directors shall approve a sale of all or substantially all of the assets of the Company, and such transaction shall have been consummated; or

(v) the Company’s Board of Directors shall approve any merger, consolidation, or like business combination or reorganization of the Company, the consummation of which would result in the occurrence of any event described in clause (ii) or (iii) above, and such transaction shall have been consummated.

Notwithstanding the foregoing, (A) any spin-off of a division or subsidiary of the Company to its stockholders and (B) any event listed in (i) through (v) above that the Board of Directors determines not to be a Change-in-Control of the Company, shall not constitute a Change-in-Control of the Company.

For purposes of the definition of Change-in-Control, “Continuing Directors” shall mean (x) the directors of the Company in office on the date of this Agreement and (y) any successor to any such director and any additional director who after such date was nominated or selected by a majority of the Continuing Directors in office at the time of his or her nomination or selection.

4. Non-Transferability of Restricted Stock. Except as expressly provided in Paragraph 3 hereof, prior to the applicable Vesting Dates, no unvested shares of the Restricted Stock (nor any interest therein) may be sold, assigned, transferred, pledged, hypothecated or otherwise disposed of, shall not be assignable by operation of law and shall not be subject to execution, attachment or similar process. Any attempted sale, assignment, transfer, pledge, hypothecation or other disposition of any unvested shares of the Restricted Stock contrary to the provisions hereof shall be null and void and without effect.

5. Forfeiture.

A. Except upon occurrence of the events set forth in Paragraphs 3(a)(i), 3(a)(ii) and 3(a)(iii) hereof, upon termination of the Grantee’s employment with the Company and/or its subsidiaries, as applicable, prior to vesting of Beneficial Ownership in all of the shares of Restricted Stock, and notwithstanding the provisions of Paragraph 3(a) hereof, Beneficial Ownership of the remaining unvested shares of the Restricted Stock shall not vest in the Grantee and all such unvested shares of the Restricted Stock shall immediately thereupon be forfeited by the Grantee to the Company (a “Forfeiture”) without any consideration therefor.

B. Upon a Forfeiture, the Grantee shall, within ten (10) business days thereafter, deliver to the Company all stock certificates representing all shares of the forfeited Restricted Stock, together with stock powers duly executed in blank by the Grantee. From and after the occurrence of such Forfeiture, and notwithstanding any provision herein to the contrary including, without limitation, the provisions of Paragraph 1 hereof, the Grantee shall have no rights to or interests in any shares of the forfeited Restricted Stock (other than the obligation to transfer and deliver all stock certificates representing all shares of forfeited Restricted Stock pursuant to this Paragraph 5(b)).

6. Representations and Warranties of Grantee. The Grantee hereby represents and warrants to the Company as follows:

A. The Grantee has the legal right and capacity to enter into this Agreement and fully understands the terms and conditions of this Agreement.

B. The Grantee is acquiring the Restricted Stock for investment purposes only and not with a view to, or in connection with, the public distribution thereof in violation of the Securities Act of 1933, as amended (the “Securities Act”).

C. The Grantee understands and agrees that none of the shares of the Restricted Stock may be offered, sold, assigned, transferred, pledged, hypothecated or otherwise disposed of except in compliance with this Agreement and the Securities Act pursuant to an effective registration statement or applicable exemption from the registration requirements of the Securities Act and applicable state securities or “blue sky” laws, and then only in accordance with the SEACOR Holdings Inc. Insider Trading and Tipping Policy (the “Insider Trading Policy”). The Grantee further understands that the Company has no obligation to cause or to refrain from causing the resale of any of the shares of the Restricted Stock or any other shares of its capital stock to be registered under the Securities Act or to comply with any exemption under the Securities Act which would permit the shares of the Restricted Stock to be sold or otherwise transferred by the Grantee. The Grantee further understands that, without approval in writing pursuant to the Insider Trading Policy, no trade may be executed in any interest or position relating to the future price of Company securities, such as a put option, call option, or short sale (which prohibition includes, among other things, establishing any “collar” or other mechanism for the purpose of establishing a price).

7. Notices. Any notice required or permitted hereunder shall be deemed given only when delivered personally or when deposited in a United States Post Office as certified mail, postage prepaid, addressed, as appropriate, if to the Grantee, at such address as the Company shall maintain for the Grantee in its personnel records or such other address as he may designate in writing to the Company, and if to the Company, at 2200 Eller Drive, PO Box 13038, Fort Lauderdale, FL 33316, Attention: Corporate Secretary or such other address as the Company may designate in writing to the Grantee.

8. Withholding. All payments or distributions of Restricted Stock or with respect thereto shall be net of any amounts required to be withheld pursuant to applicable federal, national, state and local tax withholding requirements. The Company may require the Grantee to remit to it an amount sufficient to satisfy such tax withholding requirements prior to delivery of any certificates for such Restricted Stock or with respect thereto. In lieu thereof, the Company shall have the right to withhold the amount of such taxes from any other sums due or to become due from such corporation to the Grantee as the Company shall determine. The Company may, in its discretion and subject to such rules as it may adopt (including any as may be required to satisfy applicable tax and/or non-tax regulatory requirements), permit the Grantee to pay all or a portion of the federal, national, state and local withholding taxes arising in connection with the Restricted Stock or any payments or distributions with respect thereto by electing to have the Company withhold Common Shares having a Fair Market Value equal to the amount to be withheld, provided that such withholding shall only be at rates required by applicable statues or regulations.

9. Failure to Enforce Not a Waiver. The failure of the Company to enforce at any time any provision of this Agreement shall in no way be construed to be a waiver of such provision or of any other provision hereof.

10. Amendment and Termination. This Agreement may not be amended or terminated unless such amendment or termination is in writing and duly executed by each of the parties hereto.

11. Tenure. The Grantee’s right to continue to serve the Company or any of its subsidiaries as an officer, employee, or otherwise, shall not be enlarged or otherwise affected by the award hereunder.

12. Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed to be an original, but all of which together shall constitute but one and the same instrument.

13. Benefit and Binding Effect. This Agreement shall be binding upon and shall inure to the benefit of the Company, its successors and assigns, and the Grantee, his executors, administrators, personal representatives and heirs. In the event that any part of this Agreement shall be held to be invalid or unenforceable, the remaining parts hereof shall nevertheless continue to be valid and enforceable as though the invalid portions were not a part hereof.

14. Entire Agreement. This Agreement contains the entire understanding of the parties hereto with respect to the subject matter hereof and supersedes all prior agreements, discussions and understandings with respect to such subject matter.

15. Governing Law. This Agreement shall be governed by, and construed and enforced in accordance with, the laws of the State of Delaware, without giving effect to principles and provisions thereof relating to conflict or choice of laws.

16. Amended 2007 Share Incentive Plan Controls. This agreement is subject to all terms and provisions of the SEACOR Holdings Inc. Amended 2007 Share Incentive Plan (the “Plan”), which are incorporated herein by reference. In the event of any conflict, the terms and provisions of the Plan shall control over the terms and provisions of this Agreement. All capitalized terms herein shall have the meanings given to such terms by the Plan unless otherwise defined herein or unless the context clearly indicates otherwise.

IN WITNESS WHEREOF, the Company has executed this Agreement on the date and year first above written.
