Item 1. Business
THE COMPANY

Kirby Corporation (the “Company”) was incorporated in Nevada on January 31, 1969 as a subsidiary of Kirby Industries, Inc. (“Industries”). The Company became publicly owned on September 30, 1976 when its common stock was distributed pro rata to the stockholders of Industries in connection with the liquidation of Industries. At that time, the Company was engaged in oil and gas exploration and production, marine transportation and property and casualty insurance. Since then, through a series of acquisitions and divestitures, the Company has become a marine transportation and diesel engine services company. In 1990, the name of the Company was changed from “Kirby Exploration Company, Inc.” to “Kirby Corporation” because of the changing emphasis of its business. Today, the Company is the nation’s largest domestic tank barge operator, transporting bulk liquid products throughout the Mississippi River System, on the Gulf Intracoastal Waterway, coastwise along all three United States coasts and in Alaska and Hawaii. The Company transports petrochemicals, black oil, refined petroleum products and agricultural chemicals by tank barge. The Company also operates eight offshore barge and tug units transporting dry-bulk commodities in United States coastal trade. Through its diesel engine services segment, the Company provides after-market services for medium-speed and high-speed diesel engines, reduction gears and ancillary products for marine and power generation applications, distributes and services high-speed diesel engines and transmissions, pumps and compression products, and manufactures and remanufacturers oilfield service equipment, including pressure pumping units, for land-based pressure pumping and oilfield service markets.

Unless the context otherwise requires, all references herein to the Company include the Company and its subsidiaries.

The Company’s principal executive office is located at 55 Waugh Drive, Suite 1000, Houston, Texas 77007, and its telephone number is (713) 435-1000. The Company’s mailing address is P.O. Box 1745, Houston, Texas 77251-1745.

BUSINESS AND PROPERTY

The Company, through its subsidiaries, conducts operations in two business segments: marine transportation and diesel engine services.

The Company, through its marine transportation segment, is a provider of marine transportation services, operating tank barges and towing vessels transporting bulk liquid products throughout the Mississippi River System, on the Gulf Intracoastal Waterway, coastwise along all three United States coasts and in Alaska and Hawaii. The Company transports petrochemicals, black oil, refined petroleum products and agricultural chemicals by tank barge. The Company operates offshore dry-bulk barge and tugboat units engaged in the offshore transportation of dry-bulk cargoes in United States coastal trade. The segment is a provider of transportation services for its customers and, in almost all cases, does not assume ownership of the products that it transports. All of the Company’s vessels operate under the United States flag and are qualified for domestic trade under the Jones Act.

The Company, through its diesel engine services segment, sells genuine replacement parts, provides service mechanics to overhaul and repair medium-speed and high-speed diesel engines, transmissions, reduction gears, pumps and compression products, maintains facilities to rebuild component parts or entire medium-speed and high-speed diesel engines, transmissions and entire reduction gears, and manufactures and remanufactures oilfield service equipment, including pressure pumping units. The Company primarily services the marine, power generation and land-based oil and gas operator and producer markets.

The Company and its marine transportation and diesel engine services segments have approximately 4,575 employees, substantially all of whom are in the United States.

The 253 inland towboats, 76 coastal tugboats, eight offshore tugboats and one docking tugboat provide the power source and the 861 inland tank barges, 72 coastal tank barges and eight offshore dry-bulk cargo barges provide the freight capacity for the marine transportation segment. When the power source and freight capacity are combined, the unit is called a tow. The Company’s inland tows generally consist of one towboat and from one to 25 tank barges, depending upon the horsepower of the towboat, the river or canal capacity and conditions, and customer requirements. The Company’s coastal and offshore tows primarily consist of one tugboat and one tank barge or dry-bulk cargo barge.
Marine Transportation Industry Fundamentals

The United States inland waterway system, composed of a network of interconnected rivers and canals that serve the nation as water highways, is one of the world’s most efficient transportation systems. The nation’s inland waterways are vital to the United States distribution system, with over 1.1 billion short tons of cargo moved annually on United States shallow draft waterways. The inland waterway system extends approximately 26,000 miles, 12,000 miles of which are generally considered significant for domestic commerce, through 38 states, with 635 shallow draft ports. These navigable inland waterways link the United States heartland to the world.

The United States coastal system consists of ports along the Atlantic, Gulf and Pacific coasts, as well as ports in Alaska, Hawaii and on the Great Lakes. Like the inland waterways, the coastal trade is vital to the United States distribution system, particularly the regional distribution of refined petroleum products from refineries and storage facilities to a variety of destinations, including other refineries, distribution terminals, power plants and ships. In addition to distribution directly from refineries and storage facilities, coastal tank barges are used frequently to distribute products from pipelines. Many coastal markets receive refined products principally from coastal tank barges.  Smaller volumes of petrochemicals are distributed from Gulf Coast plants to end users and black oil, including crude oil and natural gas condensate, are distributed regionally from refineries and terminals along the United States coast to refineries, power plants and distribution terminals.

Based on cost and safety, barge transportation is often the most efficient and safest means of transporting bulk commodities when compared with railroads and trucks. The cargo capacity of a 27,500 barrel inland tank barge is the equivalent of 46 railroad tank cars or 144 tractor-trailer tank trucks. A typical Company lower Mississippi River linehaul tow of 15 barges has the carrying capacity of approximately 216 railroad tank cars plus six locomotives, or approximately 1,050 tractor-trailer tank trucks. The Company’s inland tank barge fleet capacity of 17.3 million barrels equates to approximately 28,900 railroad tank cars or approximately 90,400 tractor-trailer tank trucks. Furthermore, barging is much more energy efficient. One ton of bulk product can be carried 616 miles by inland barge on one gallon of fuel, compared with 478 miles by railcars or 150 miles by truck. In the coastal trade, the carrying capacity of a 100,000 barrel tank barge is the equivalent of approximately 165 railroad tank cars or approximately 525 tractor-trailer tank trucks. The Company’s coastal tank barge fleet capacity of 6.0 million barrels equates to approximately 9,900 railroad tank cars or approximately 31,600 tractor-trailer tank trucks.

Tank barge transportation is safer than most modes of transportation in the United States. Marine transportation generally involves less urban exposure than railroad or truck transportation and operates on a system with few crossing junctures and in areas relatively remote from population centers. These factors generally reduce both the number and impact of waterway incidents.

Inland Tank Barge Industry

The Company operates within the United States inland tank barge industry, a diverse and independent mixture of large integrated transportation companies and small operators, as well as captive fleets owned by United States refining and petrochemical companies. The inland tank barge industry provides marine transportation of bulk liquid cargoes for customers and, in the case of captives, for their own account, throughout the Mississippi River and its tributaries and on the Gulf Intracoastal Waterway. The most significant markets in this industry include the transportation of petrochemicals, black oil, refined petroleum products and agricultural chemicals. The Company operates in each of these markets. The use of marine transportation by the petroleum and petrochemical industry is a major reason for the location of United States refineries and petrochemical facilities on navigable inland waterways. Texas and Louisiana currently account for approximately 80% of the United States production of petrochemicals. Much of the United States farm belt is likewise situated with access to the inland waterway system, relying on marine transportation of farm products, including agricultural chemicals. The Company’s principal distribution system encompasses the Gulf Intracoastal Waterway from Brownsville, Texas, to Port St. Joe, Florida, the Mississippi River System and the Houston Ship Channel. The Mississippi River System includes the Arkansas, Illinois, Missouri, Ohio, Red, Tennessee, Yazoo, Ouachita and Black Warrior Rivers and the Tennessee-Tombigbee Waterway.
The number of tank barges that operate on the inland waterways of the United States declined from an estimated 4,200 in 1982 to 2,900 in 1993, remained relatively constant at 2,900 until 2002, decreased to 2,750 from 2002 through 2006, and then increased over the years to approximately 3,450 by the end of 2013. The Company believes the decrease from 4,200 in 1982 to 2,750 in 2006 primarily resulted from: the increasing age of the domestic tank barge fleet, resulting in scrapping; rates inadequate to justify new construction; a reduction in tax incentives, which previously encouraged speculative construction of new equipment; stringent operating standards to adequately cope with safety and environmental risk; the elimination of government regulations and programs supporting the many new small refineries and a proliferation of oil traders which created a strong demand for tank barge services; an increase in the average capacity per barge; and an increase in environmental regulations that mandate expensive equipment modification, which some owners were unwilling or unable to undertake given capital constraints and the age of their fleets. The cost of tank barge hull work for required periodic United States Coast Guard (“USCG”) certifications, as well as general safety and environmental concerns, force operators to periodically reassess their ability to recover maintenance costs. The increase from 2,750 in 2006 to approximately 3,450 by the end of 2013 primarily resulted from increased barge construction and deferred retirements due to strong demand and resulting capacity shortages.  The Company’s 861 inland tank barges represent approximately 25% of the industry’s 3,450 inland tank barges.

For 2011, the Company estimated that industry wide 160 tank barges were placed in service and 125 tank barges were retired. Due to the improved demand during 2011 for inland petrochemical and black oil barges and federal tax incentives on new equipment, the Company estimated that industry wide 260 tank barges were placed in service during 2012 and 110 tank barges were retired. For 2013, the Company estimated that industry wide 270 tank barges were placed in service and 70 tank barges were retired.  During 2013, due to continued strong demand, the Company estimates that approximately 260 tank barges were ordered for delivery throughout 2014 and many older tank barges will be retired, dependent on 2014 market conditions. The risk of an oversupply of tank barges may be mitigated by continued increased petrochemical, black oil and refined petroleum products volumes and the fact that the inland tank barge industry has a mature fleet, with approximately 850 tank barges over 30 years old and approximately 500 of those over 35 years old, which may lead to retirement of older tank barges.

The average age of the nation’s inland tank barge fleet is approximately 18 years. Single hull barges comprise approximately 1% of the nation’s tank barge fleet, with an average age of 40 years. The Company does not operate any single hull inland tank barges. Single hull barges are being driven from the nation’s tank barge fleet by market forces, stringent environmental regulations and rising maintenance costs. Single hull tank barges are required by current federal law to be retrofitted with double hulls or phased out of domestic service by December 31, 2014. Market bias has also resulted in reduced lives for single hull tank barges industry wide.

The Company’s inland marine transportation segment also owns a two-thirds interest in Osprey Line, L.L.C. (“Osprey”), a transporter of project cargoes and cargo containers by barge on the United States inland waterway system, as well as a 51% interest in a shifting operation and fleeting facility for dry cargo barges and tank barges on the Houston Ship Channel.

Coastal Tank Barge Industry

The Company also operates in the United States coastal tank barge industry, operating tank barges in the 195,000 barrel or less category. This market is composed of approximately 15 large integrated transportation companies and small operators. The 195,000 barrel or less category coastal tank barge industry primarily provides regional marine transportation distribution of bulk liquid cargoes along the United States Atlantic, Gulf and Pacific coasts, in Alaska and Hawaii and to a lesser extent on the Great Lakes. Products transported are primarily refined petroleum products and black oil from refineries and storage facilities to a variety of destinations, including other refineries, distribution terminals, power plants and ships, the regional movement of crude oil and gas condensate to Gulf Coast, Northeast and West Coast refineries and the movement of petrochemicals primarily from Gulf Coast petrochemical facilities to end users.

The number of coastal tank barges that operate in the 195,000 barrel or less category is approximately 265, of which the Company operates 72 or approximately 27%. The average age of the nation’s coastal tank barge fleet is approximately 15 years.
Competition in the Tank Barge Industry

The tank barge industry remains very competitive. Competition in this business has historically been based primarily on price; however, most of the industry’s customers, through an increased emphasis on safety, the environment, quality and a trend toward a “single source” supply of services, are more frequently requiring that their supplier of tank barge services have the capability to handle a variety of tank barge requirements. These requirements include distribution capability throughout the inland waterway system and coastal markets, with high levels of flexibility, safety, environmental responsibility and financial responsibility, as well as adequate insurance and high quality of service consistent with the customer’s own operational standards.

In the inland markets, the Company’s direct competitors are primarily noncaptive inland tank barge operators. “Captive” fleets are owned by major oil and petrochemical companies which occasionally compete in the inland tank barge market, but primarily transport cargoes for their own account. The Company is the largest inland tank barge carrier, both in terms of number of barges and total fleet barrel capacity. The Company’s inland tank barge fleet has grown from 71 tank barges in 1988 to 861 tank barges as of February 21, 2014, or approximately 25% of the estimated total number of domestic inland tank barges.

In the coastal markets, the Company’s direct competitors are the operators of United States tank barges in the 195,000 barrels or less category.  Coastal tank barges in the 195,000 barrels or less category have the ability to enter the large majority of coastal ports.  Ocean-going tank barges and United States refined petroleum products tankers, in the 300,000 barrels plus category, including the captive fleets of major oil companies, primarily move large volumes of refined petroleum products and crude oil from the Gulf Coast to the Northeast.  There are approximately 35 such vessels and, because of their size, their access to ports is limited by terminal size and draft restrictions.

While the Company competes primarily with other tank barge companies, it also competes with companies who operate refined product and petrochemical pipelines, railroad tank cars and tractor-trailer tank trucks. As noted above, the Company believes that both inland and coastal marine transportation of bulk liquid products enjoys a substantial cost advantage over railroad and truck transportation. The Company believes that refined product and crude oil pipelines, although often a less expensive form of transportation than inland and coastal tank barges, are not as adaptable to diverse products and are generally limited to fixed point-to-point distribution of commodities in high volumes over extended periods of time.

Marine Transportation Acquisitions

On December 14, 2012, the Company completed the acquisition of Penn Maritime Inc. and Maritime Investments LLC (“Penn”), an operator of tank barges and tugboats participating in the coastal transportation of primarily refinery feedstocks, asphalt and crude oil in the United States. The total value of the transaction was $300,538,000, consisting of $146,750,000 of cash, $29,080,000 through the issuance of 500,000 shares of Company common stock valued at $58.16 per share, and $124,708,000 of cash for the retirement of Penn’s debt. Penn’s fleet, comprised of 18 double hull tank barges with a capacity of 1.9 million barrels and 16 tugboats, operated along the East Coast and Gulf Coast of the United States and primarily transported refinery feedstocks, asphalt and crude oil.

On November 1, 2012, the Company purchased from Allied Transportation Company (“Allied”) 10 coastal tank barges with a total capacity of 680,000 barrels, three offshore dry-bulk barges with a total capacity of 48,000 deadweight tons and seven coastal tugboats for $108,547,000 in cash plus a provision for up to $10,000,000 that will be paid contingent on developments with the sugar provisions in the United States Farm Bill. The fair value of the contingent liability recorded at the acquisition date was $9,756,000. A payment of $5,000,000 was made in the 2013 first quarter on the contingent liability. Allied provided coastal transportation of petrochemicals as well as dry sugar products in the Northeast, Atlantic and Gulf Coast regions of the United States.

On December 15, 2011, the Company completed the purchase of the coastal tank barge fleet of Seaboats, Inc. and affiliated companies (“Seaboats”) consisting of three 80,000 barrel coastal tank barge and tugboats for $42,745,000 in cash. The three coastal tank barge and tugboats currently operate along the United States East Coast and had an average age of five years.
On July 1, 2011, the Company completed the acquisition of K-Sea Transportation Partners L.P. (“K-Sea”) an operator of tank barges and tugboats participating in the coastal transportation primarily of refined petroleum products in the United States. The total value of the transaction was $603,427,000, excluding transaction fees, consisting of $227,617,000 of cash paid to K-Sea common and preferred unit holders and the general partner, $262,791,000 of cash to retire K-Sea’s outstanding debt, and $113,019,000 through the issuance of 1,939,234 shares of Company common stock valued at $58.28 per share, the Company’s closing share price on July 1, 2011.

On April 17, 2012, the Company changed the name of K-Sea to Kirby Offshore Marine, LLC (“Kirby Offshore Marine”) to more fully integrate the Company’s coastal operations with the Company’s inland marine transportation operations. The acquired company is referred to in this report as either K-Sea or Kirby Offshore Marine, depending on the context.

On the acquisition date, Kirby Offshore Marine's fleet, comprised of 57 coastal tank barges with a capacity of 3.8 million barrels and 63 tugboats, operated along the East Coast, West Coast and Gulf Coast of the United States, as well as in Alaska and Hawaii. Kirby Offshore Marine's tank barge fleet, 54 of which were double hulled and had an average age of approximately nine years, is one of the youngest fleets in the coastal trade. Kirby Offshore Marine's customers include major oil companies and refiners, many of which are current Company customers for inland tank barge services. Kirby Offshore Marine has operating facilities in New York, Seattle and Honolulu.

On February 24, 2011, the Company purchased 21 inland and offshore tank barges and 15 inland towboats and offshore tugboats from Enterprise Marine Services LLC (“Enterprise”) for $53,200,000 in cash. Enterprise provided transportation and delivery services for ship bunkers (engine fuel) to cruise ships, container ships and freighters primarily in the Miami, Port Everglades and Cape Canaveral, Florida area, the three largest cruise ship ports in the United States, as well as Tampa, Florida, Mobile, Alabama and Houston, Texas.

On February 9, 2011, the Company purchased from Kinder Morgan Petcoke, L.P. (“Kinder Morgan”) for $4,050,000 in cash a 51% interest in Kinder Morgan’s shifting operation and fleeting facility for dry cargo barges and tank barges on the Houston Ship Channel. Kinder Morgan retained the remaining 49% interest and the Company will manage the operation. In addition, the Company purchased a towboat from Kinder Morgan for $1,250,000 in cash.

Products Transported

The Company transports petrochemicals, black oil, refined petroleum products and agricultural chemicals by tank barge throughout the Mississippi River System, on the Gulf Intracoastal Waterway, coastwise along all three United States coasts and in Alaska and Hawaii. During 2013, the Company’s inland marine transportation operation moved over 51 million tons of liquid cargo on the United States inland waterway system.

Petrochemicals. Bulk liquid petrochemicals transported include such products as benzene, styrene, methanol, acrylonitrile, xylene and caustic soda, all consumed in the production of paper, fibers and plastics. Pressurized products, including butadiene, isobutane, propylene, butane and propane, all requiring pressurized conditions to remain in stable liquid form, are transported in pressure barges. The transportation of petrochemical products represented 47% of the segment’s 2013 revenues. Customers shipping these products are petrochemical and refining companies.

Black Oil. Black oil transported includes such products as residual fuel oil, No. 6 fuel oil, coker feedstock, vacuum gas oil, asphalt, carbon black feedstock, crude oil, gas condensate and ship bunkers (engine fuel). Such products represented 25% of the segment’s 2013 revenues. Black oil customers are refining companies, marketers and end users that require the transportation of black oil between refineries and storage terminals, to refineries and to power plants. Ship bunker customers are oil companies and oil traders in the bunkering business.
Refined Petroleum Products. Refined petroleum products transported include the various blends of finished gasoline, gasoline blendstocks, jet fuel, No. 2 oil, naphtha, heating oil and diesel fuel, and represented 24% of the segment’s 2013 revenues. The Company also classifies ethanol in the refined petroleum products category. Customers are oil and refining companies, marketers and ethanol producers.

Agricultural Chemicals. Agricultural chemicals transported represented 4% of the segment’s 2013 revenues. They include anhydrous ammonia and nitrogen-based liquid fertilizer, as well as industrial ammonia. Agricultural chemical customers consist mainly of domestic and foreign producers of such products.

Demand Drivers in the Tank Barge Industry

Demand for tank barge transportation services is driven by the production volumes of the bulk liquid commodities transported by barge. Marine transportation demand for the segment’s four primary commodity groups, petrochemicals, black oil, refined petroleum products and agricultural chemicals, is based on differing circumstances. While the demand drivers of each commodity are different, the Company has the flexibility in certain cases of re-allocating inland equipment and coastal equipment between the petrochemical and refined products markets as needed.

Bulk petrochemical volumes have historically tracked the general domestic economy and correlate to the United States Gross Domestic Product. However, since late 2010, inland petrochemical tank barge utilization levels have remained strong, in the 90% to 95% range. While the United States economy remains sluggish with consistently high unemployment levels, the United States petrochemical industry continues to see strong production levels for both domestic consumption and exports. Low priced domestic natural gas, a basic feedstock for the United States petrochemical industry, provides the industry with a competitive advantage against foreign petrochemical producers. As a result, United States petrochemical production has remained strong during 2013, 2012 and 2011, thereby producing increased marine transportation volumes of basic petrochemicals to both domestic consumers and terminals for export destinations. Petrochemical products are used primarily in consumer non-durable and durable goods. With the Allied acquisition on November 1, 2012, the Company moves petrochemicals from Gulf Coast petrochemical plants primarily to East Coast destinations.  Coastal tank barge utilization levels for the transportation of petrochemicals during 2013 were in the 90% level.

The demand for black oil, including ship bunkers, varies by type of product transported. Demand for transportation of residual oil, a heavy by-product of refining operations, varies with refinery utilization and usage of feedstocks. During 2013, 2012 and 2011, inland black oil tank barge utilization levels have remained strong, in the 90% to 95% range, due to strong demand driven by steady refinery production levels from major customers, the export of diesel fuel and heavy fuel oil, demand for crude oil and gas condensate transportation from the Eagle Ford shale formations in South Texas along the Gulf Intracoastal Waterway, and for the movement of Canadian, Bakken and Utica crude oil downriver from the Midwest to the Gulf Coast. Coastal black oil tank barge utilization levels improved from approximately 75% during 2011 and 2012 to the 90% level in 2013, partly attributable to the Penn acquisition on December 14, 2012, moving black oil, specifically residual fuel oil and asphalt along the United States East and Gulf Coasts.  In addition, starting in 2012 and continuing throughout 2013, coastal tank barges are moving Eagle Ford crude oil in the Gulf of Mexico, Bakken crude oil from Albany, New York down the Hudson River to East Coast refineries, and starting in late 2013 began moving Bakken crude oil from the Columbia River to West Coast refineries.  Inland and coastal asphalt shipments are generally seasonal, with higher volumes shipped during April through November, months when weather allows for efficient road construction. Carbon black feedstock shipments generally track the general economy and are used in the production of automobiles and related parts, and in housing applications. In August 2013, the Company sold its New York Harbor bunkering barges and tugboats, thereby exiting the New York Harbor ship bunker market.

Refined petroleum product volumes are driven by United States gasoline and diesel fuel consumption, principally vehicle usage, air travel and weather conditions. Volumes can also relate to gasoline inventory imbalances within the United States. Generally, gasoline and No. 2 oil are exported from the Gulf Coast where refining capacity exceeds demand. The Midwest is a net importer of such products. Volumes were also driven by heavier volumes of diesel fuel transported to terminals along the Gulf Coast for export to South America. Ethanol, produced in the Midwest, is moved from the Midwest to Gulf Coast customers; however, during 2012 and 2013 ethanol volumes declined due to the high price of corn, the major feedstock for United States ethanol production. In the coastal trade, tank barges are frequently used regionally to transport refined petroleum products from a coastal refinery or terminals served by pipelines to the end markets. Many coastal areas have access to refined petroleum products only by using marine transportation as the last link in the distribution chain.
Demand for marine transportation of domestic and imported agricultural fertilizer is directly related to domestic nitrogen-based liquid fertilizer consumption, driven by the production of corn, cotton and wheat. During periods of high natural gas prices, the manufacturing of nitrogen-based liquid fertilizer in the United States is curtailed. During these periods, imported products, which normally involve longer barge trips, replace the domestic products to meet Midwest and south Texas demands. Such products are delivered to the numerous small terminals and distributors throughout the United States farm belt.

Marine Transportation Operations

The marine transportation segment operates a fleet of 861 inland tank barges and 253 inland towboats, as well as 72 coastal tank barges and 76 coastal tugboats. The segment also operates eight offshore barge and tugboats units transporting dry-bulk commodities in coastal trade.

Inland Operations. The segment’s inland operations are conducted through a wholly owned subsidiary, Kirby Inland Marine, LP (“Kirby Inland Marine”). Kirby Inland Marine’s operations consist of the Canal, Linehaul and River fleets, as well as barge fleeting services.

The Canal fleet transports petrochemical feedstocks, processed chemicals, pressurized products, black oil, and refined petroleum products along the Gulf Intracoastal Waterway, the Mississippi River below Baton Rouge, Louisiana, and the Houston Ship Channel. Petrochemical feedstocks and certain pressurized products are transported from one plant to another plant for further processing. Processed chemicals and certain pressurized products are moved to waterfront terminals and chemical plants. Black oil is transported to waterfront terminals and products such as No. 6 fuel oil are transported directly to the end users. Refined petroleum products are transported to waterfront terminals along the Gulf Intracoastal Waterway for distribution.

The Linehaul fleet transports petrochemical feedstocks, chemicals, agricultural chemicals and lube oils along the Gulf Intracoastal Waterway, Mississippi River and the Illinois and Ohio Rivers. Loaded tank barges are staged in the Baton Rouge area from Gulf Coast refineries and petrochemical plants, and are transported from Baton Rouge to waterfront terminals and plants on the Mississippi, Illinois and Ohio Rivers, and along the Gulf Intracoastal Waterway, on regularly scheduled linehaul tows. Barges are dropped off and picked up going up and down river.

The River fleet transports petrochemical feedstocks, chemicals, refined petroleum products, agricultural chemicals and black oil along the Mississippi River System above Baton Rouge. The River fleet operates unit tows, where a towboat and generally a dedicated group of barges operate on consecutive voyages between loading and discharge points. Petrochemical feedstocks and processed chemicals are transported to waterfront petrochemical and chemical plants, while black oil, refined petroleum products and agricultural chemicals are transported to waterfront terminals.

The inland transportation of petrochemical feedstocks, chemicals and pressurized products is generally consistent throughout the year. Transportation of refined petroleum products, certain black oil and agricultural chemicals is generally more seasonal. Movements of black oil, such as asphalt, generally increase in the spring through fall months. Movements of refined petroleum products, such as gasoline blends, generally increase during the summer driving season, while heating oil movements generally increase during the winter months. Movements of agricultural chemicals generally increase during the spring and fall planting seasons.

The marine transportation inland operation moves and handles a broad range of sophisticated cargoes. To meet the specific requirements of the cargoes transported, the inland tank barges may be equipped with self-contained heating systems, high-capacity pumps, pressurized tanks, refrigeration units, stainless steel tanks, aluminum tanks or specialty coated tanks. Of the 861 inland tank barges currently operated, 670 are petrochemical and refined products barges, 118 are black oil barges, 58 are pressure barges, 10 are refrigerated anhydrous ammonia barges and five are specialty barges. Of the 861 inland tank barges, 817 are owned by the Company and 44 are leased.
The fleet of 253 inland towboats ranges from 800 to 5200 horsepower. Of the 253 inland towboats, 179 are owned by the Company and 74 are chartered. Towboats in the 800 to 2100 horsepower classes provide power for barges used by the Canal and Linehaul fleets on the Gulf Intracoastal Waterway and the Houston Ship Channel. Towboats in the 1400 to 3200 horsepower classes provide power for both the River and Linehaul fleets on the Gulf Intracoastal Waterway and the Mississippi River System. Towboats above 3600 horsepower are typically used on the Mississippi River System to move River fleet unit tows and provide Linehaul fleet towing. Based on the capabilities of the individual towboats used in the Mississippi River System, the tows range in size from 10,000 to 30,000 tons.

Marine transportation services for inland movements are conducted under long-term contracts, typically ranging from one to five years, some of which have renewal options, with customers with whom the Company has traditionally had long-standing relationships, as well as under spot contracts. During 2013, 2012 and 2011 approximately 75% of inland marine transportation revenues were from term contracts and 25% from spot contracts.

All of the Company’s inland tank barges used in the transportation of bulk liquid products are of double hull construction and, where applicable, are capable of controlling vapor emissions during loading and discharging operations in compliance with occupational health and safety regulations and air quality regulations.

The Company is one of the few inland tank barge operators with the ability to offer to its customers’ distribution capabilities throughout the Mississippi River System and the Gulf Intracoastal Waterway. Such distribution capabilities offer economies of scale resulting from the ability to match tank barges, towboats, products and destinations more efficiently.

Through the Company’s proprietary vessel management computer system, the fleet of barges and towboats is dispatched from a centralized dispatch at the corporate office. The towboats are equipped with satellite positioning and communication systems that automatically transmit the location of the towboat to the Company’s customer service department located in its corporate office. Electronic orders are communicated to the vessel personnel with reports of towing activities communicated electronically back to the customer service department. The electronic interface between the customer service department and the vessel personnel enables more effective matching of customer needs to barge capabilities, thereby maximizing utilization of the tank barge and towboat fleet. The Company’s customers are able to access information concerning the movement of their cargoes, including barge locations, through the Company’s web site.

Kirby Inland Marine operates the largest commercial tank barge fleeting service (temporary barge storage facilities) in numerous ports, including Houston, Corpus Christi and Freeport, Texas, Baton Rouge and New Orleans, Louisiana and other locations on the Mississippi River. Included in the fleeting service is a 51% interest and management control of a shifting operation and fleeting service for dry cargo barges and tank barges on the Houston Ship Channel. Kirby Inland Marine provides service for its own barges, as well as outside customers, transferring barges within the areas noted, as well as fleeting barges.

Kirby Inland Marine also provides shore-based tankerman and support services to the Company and third parties. Services provided include barge tankermen, marine terminal, refinery and chemical plant dock operators, and terminal management services. Services to the Company and third parties cover the Gulf Coast, mid-Mississippi Valley, and the Ohio River Valley.

The Company owns a two-thirds interest in Osprey, which transports project cargoes and cargo containers by barge on the United States inland waterway system.

Coastal Operations. The segment’s coastal operations are conducted through wholly owned subsidiaries, Kirby Offshore Marine and Kirby Ocean Transport Company (“Kirby Ocean Transport”).

Kirby Offshore Marine provides marine transportation of refined petroleum products, petrochemicals and black oil in coastal regions of the United States. The coastal operations consist of the Atlantic, Pacific and Hawaii Divisions.
The Atlantic Division primarily operates along the eastern seaboard of the United States and along the Gulf Coast. The Atlantic Division vessels call on coastal states from Maine to Texas, servicing refineries, storage terminals and power plants. The Atlantic Division also operates equipment, to a lesser extent, in the Eastern Canadian provinces. The tank barges and tugboats operating in the Atlantic Division are among the largest, with tank barges ranging in the 18,000 to 188,000 barrel capacity range and coastal tugboats in the 1800 to 8000 horsepower range, transporting primarily refined petroleum products, petrochemicals and black oil. In August 2013, the Company sold its New York Harbor bunkering barges and tugboats, thereby exiting the New York Harbor ship bunker market.

The Pacific Division primarily operates along the Pacific Coast of the United States, servicing refineries and storage terminals from Southern California to Washington State, throughout Alaska, including Dutch Harbor, Cook Inlet and the Alaska River Systems, and from California to Hawaii. The Pacific Division’s fleet consists of tank barges in the 16,000 to 193,000 barrel capacity range and tugboats in the 2000 to 11000 horsepower range, transporting primarily refined petroleum products.  Beginning in late 2013, the Pacific Division began transporting crude oil from the terminals on the Columbia River to West Coast refineries.

The Hawaii Division services local petroleum retailers and oil companies distributing refined petroleum products and black oil between the Hawaiian Islands and provides other services to the local maritime community. The Hawaii Division’s fleet consists of tank barges in the 53,000 to 86,000 barrel capacity range and tugboats in the 1000 to 5000 horsepower range, transporting refined petroleum products for local and regional customers, black oil to power generation customers and delivering bunker fuel to ships. The Hawaii Division also provides service docking, standby tug assistance and line handling to vessels using the Single Point Mooring installation at Barbers Point, Oahu, a facility for large tankers to safely load and discharge their cargos through an offshore buoy and submerged pipeline without entering the port.

The coastal transportation of refined petroleum products and black oil is impacted by seasonality, partially dependent on the area of operations. Operations along the West Coast and in Alaska have been subject to more seasonal variations in demand than the operations along the East Coast and Gulf Coast regions. Seasonality generally does not impact the Hawaiian market. Movements of refined petroleum products such as various blends of gasoline are strongest during the summer driving season while heating oil generally increases during the winter months.

The coastal fleet consists of 72 tank barges, 71 of which are double hull and one is single hull, with 6.0 million barrels of capacity, primarily transporting refined petroleum products, black oil and petrochemicals. Of the 72 coastal tank barges currently operating, 46 are refined products and petrochemical barges and 26 are black oil barges. The Company owns 61 of the coastal tank barges and 11 are leased. The Company operates 76 coastal tugboats ranging from 1000 to 11000 horsepower, 69 of which are owned and seven are chartered.

Coastal marine transportation services are conducted under long-term contracts, primarily one year or longer, some of which have renewal options for customers with which the Company has traditionally had long-standing relationships, as well as under spot contracts. During 2013, approximately 75% of the coastal marine transportation revenues were under term contracts and 25% were spot contract revenues, compared with 60% under term contracts and 40% under spot contracts during 2012.

Kirby Offshore Marine also operates a fleet of three offshore dry-bulk barges and tugboats involved in the transportation of sugar and other dry products between Florida and East Coast ports. These vessels primarily operate under contracts of affreightment that are typically one year or less in length.

Kirby Ocean Transport owns and operates a fleet of five offshore dry-bulk barges, five offshore tugboats and one docking tugboat. Kirby Ocean Transport operates primarily under term contracts of affreightment, including a contract that expires in 2020 with Progress Energy Florida (“PEF”) to transport coal across the Gulf of Mexico to PEF’s power generation facility at Crystal River, Florida.
Kirby Ocean Transport has a contract with Holcim (US) Inc. (“Holcim”) to transport Holcim’s limestone requirements from a facility adjacent to the PEF facility at Crystal River to Holcim’s plant in Theodore, Alabama. Holcim’s contract expires in December 2014. The Holcim contract provides cargo for a portion of the return voyage for the vessels that carry coal to PEF’s Crystal River facility. Kirby Ocean Transport is also engaged in the transportation of coal, fertilizer and other bulk cargoes on a short-term basis between domestic ports and occasionally the transportation of grain from domestic ports to ports primarily in the Caribbean Basin.
 
Contracts and Customers

Marine transportation inland and coastal services are conducted under term contracts, typically ranging from one to five years, some of which have renewal options, for customers with whom the Company has traditionally had long-standing relationships, as well as under spot contracts. The majority of the marine transportation contracts with its customers are for terms of one year. Most have been customers of the Company’s marine transportation segment for many years and management anticipates continued relationships; however, there is no assurance that any individual contract will be renewed.

A term contract is an agreement with a specific customer to transport cargo from a designated origin to a designated destination at a set rate (affreightment) or at a daily rate (time charter). The rate may or may not escalate during the term of the contract; however, the base rate generally remains constant and contracts often include escalation provisions to recover changes in specific costs such as fuel. Time charters, which insulate the Company from revenue fluctuations caused by weather and navigational delays and temporary market declines, represented approximately 58% of the marine transportation’s inland revenues under term contracts during 2013, 57% of revenue under term contracts during 2012 and 55% of the revenue under term contracts during 2011. A spot contract is an agreement with a customer to move cargo from a specific origin to a designated destination for a rate negotiated at the time the cargo movement takes place. Spot contract rates are at the current “market” rate and are subject to market volatility. The Company typically maintains a higher mix of term contracts to spot contracts to provide the Company with a predictable revenue stream while maintaining spot market exposure to take advantage of new business opportunities and existing customers’ peak demands. During 2011, 2012 and 2013, approximately 75% of marine transportation’s inland revenues were from term contracts and 25% from spot contracts. During 2011 and 2012, approximately 60% of marine transportation’s coastal revenues were under term contracts and 40% from spot contracts. During 2013, with the acquisitions of Allied and Penn in late 2012, along with stronger demand for coastal tank barges, approximately 75% of the coastal revenues were under term contracts and 25% from spot contracts. Coastal time charters represented approximately 90% of the marine transportation coastal revenues under term contracts during 2013, 2012 and 2011.

No single customer of the marine transportation segment accounted for more than 10% of the Company’s revenues in 2013, 2012 and 2011.

Employees

The Company’s marine transportation segment has approximately 3,275 employees, of which approximately 2,425 are vessel crew members. None of the segment’s inland operations are subject to collective bargaining agreements. The segment’s coastal operation includes approximately 875 vessel employees some of which are subject to collective bargaining agreements in certain geographic areas. Approximately 375 Kirby Offshore Marine vessel crew members employed in the Atlantic Division are subject to a collective bargaining agreement with the Richmond Terrace Bargaining Unit that is in effect through December 2014.  In addition, approximately 150 Kirby Offshore Marine vessel crew members are represented by the Seafarers International Union (“SIU”) under a collective bargaining agreement in effect through April 2015.

Properties

The principal office of Kirby Inland Marine, Kirby Offshore Marine, Kirby Ocean Transport and Osprey is located in Houston, Texas, in the Company’s facilities under a lease that expires in December 2025. Kirby Inland Marine’s operating locations are on the Mississippi River at Baton Rouge and New Orleans, Louisiana, and Greenville, Mississippi, two locations in Houston, Texas, on and near the Houston Ship Channel, one in Miami, Florida, and one in Corpus Christi, Texas. The New Orleans and Houston facilities are owned, and the Baton Rouge, Greenville, Miami and Corpus Christi facilities are leased. Kirby Offshore Marine’s operating facilities are located in Staten Island, New York, Seattle, Washington and Honolulu, Hawaii. All operating facilities are leased, including pier and wharf facilities and office and warehouse space.
Governmental Regulations

General. The Company’s marine transportation operations are subject to regulation by the USCG, federal laws, state laws and certain international conventions.

Most of the Company’s tank barges are inspected by the USCG and carry certificates of inspection. The Company’s inland and coastal towing vessels and coastal dry-bulk barges are not currently subject to USCG inspection requirements; however, regulations are currently under development that would subject inland and coastal towing vessels to USCG inspection requirements. Most of the Company’s coastal tugboats and coastal tank and dry-bulk barges are built to American Bureau of Shipping (“ABS”) classification standards and are inspected periodically by ABS to maintain the vessels in class. The crews employed by the Company aboard vessels, including captains, pilots, engineers, tankermen and ordinary seamen, are licensed by the USCG.

The Company is required by various governmental agencies to obtain licenses, certificates and permits for its vessels depending upon such factors as the cargo transported, the waters in which the vessels operate and other factors. The Company is of the opinion that the Company’s vessels have obtained and can maintain all required licenses, certificates and permits required by such governmental agencies for the foreseeable future.

The Company believes that additional security and environmental related regulations may be imposed on the marine industry in the form of contingency planning requirements. Generally, the Company endorses the anticipated additional regulations and believes it is currently operating to standards at least equal to anticipated additional regulations.

Jones Act. The Jones Act is a federal cabotage law that restricts domestic marine transportation in the United States to vessels built and registered in the United States, manned by United States citizens, and owned and operated by United States citizens. For a corporation to qualify as United States citizens for the purpose of domestic trade it is to be 75% owned and controlled by United States citizens. The Company monitors citizenship and meets the requirements of the Jones Act for its vessels.

Compliance with United States ownership requirements of the Jones Act is important to the operations of the Company, and the loss of Jones Act status could have a material negative effect on the Company. The Company monitors the citizenship of its employees and stockholders.

User Taxes. Federal legislation requires that inland marine transportation companies pay a user tax based on propulsion fuel used by vessels engaged in trade along the inland waterways that are maintained by the United States Army Corps of Engineers. Such user taxes are designed to help defray the costs associated with replacing major components of the inland waterway system, such as locks and dams. A significant portion of the inland waterways on which the Company’s vessels operate is maintained by the Army Corps of Engineers.

The Company presently pays a federal fuel user tax of 20.1 cents per gallon consisting of a .1 cent per gallon leaking underground storage tank tax and a 20 cents per gallon waterway user tax.

Security Requirements. The Maritime Transportation Security Act of 2002 requires, among other things, submission to and approval by the USCG of vessel and waterfront facility security plans (“VSP” and “FSP”, respectively). The Company’s VSP and FSP have been approved and the Company is operating in compliance with the plans for all of its vessels and facilities that are subject to the requirements.

Environmental Regulations

The Company’s operations are affected by various regulations and legislation enacted for protection of the environment by the United States government, as well as many coastal and inland waterway states.
Water Pollution Regulations. The Federal Water Pollution Control Act of 1972, as amended by the Clean Water Act of 1977, the Comprehensive Environmental Response, Compensation and Liability Act of 1981 (“CERCLA”) and the Oil Pollution Act of 1990 (“OPA”) impose strict prohibitions against the discharge of oil and its derivatives or hazardous substances into the navigable waters of the United States. These acts impose civil and criminal penalties for any prohibited discharges and impose substantial strict liability for cleanup of these discharges and any associated damages. Certain states also have water pollution laws that prohibit discharges into waters that traverse the state or adjoin the state, and impose civil and criminal penalties and liabilities similar in nature to those imposed under federal laws.

The OPA and various state laws of similar intent substantially increased over historic levels the statutory liability of owners and operators of vessels for oil spills, both in terms of limit of liability and scope of damages.

One of the most important requirements under the OPA is that all newly constructed tank barges engaged in the transportation of oil and petroleum in the United States be double hulled, and all existing single hull tank barges be retrofitted with double hulls or phased out of domestic service by December 31, 2014.

The Company manages its exposure to losses from potential discharges of pollutants through the use of well-maintained and equipped vessels, through safety, training and environmental programs, and through the Company’s insurance program. In addition, the Company’s inland fleet consists entirely of double hull barges and with only one single hull barge in the coastal fleet. There can be no assurance, however, that any new regulations or requirements or any discharge of pollutants by the Company will not have an adverse effect on the Company.

Financial Responsibility Requirement. Commencing with the Federal Water Pollution Control Act of 1972, as amended, vessels over 300 gross tons operating in the Exclusive Economic Zone of the United States have been required to maintain evidence of financial ability to satisfy statutory liabilities for oil and hazardous substance water pollution. This evidence is in the form of a Certificate of Financial Responsibility (“COFR”) issued by the USCG. The majority of the Company’s tank barges are subject to this COFR requirement, and the Company has fully complied with this requirement since its inception. The Company does not foresee any current or future difficulty in maintaining the COFR certificates under current rules.

Clean Air Regulations. The Federal Clean Air Act of 1979 requires states to draft State Implementation Plans (“SIPs”) designed to reduce atmospheric pollution to levels mandated by this act. Several SIPs provide for the regulation of barge loading and discharging emissions. The implementation of these regulations requires a reduction of hydrocarbon emissions released into the atmosphere during the loading of most petroleum products and the degassing and cleaning of barges for maintenance or change of cargo. These regulations require operators who operate in these states to install vapor control equipment on their barges. The Company expects that future emission regulations will be developed and will apply this same technology to many chemicals that are handled by barge. Most of the Company’s barges engaged in the transportation of petrochemicals, chemicals and refined products are already equipped with vapor control systems. Although a risk exists that new regulations could require significant capital expenditures by the Company and otherwise increase the Company’s costs, the Company believes that, based upon the regulations that have been proposed thus far, no material capital expenditures beyond those currently contemplated by the Company and no material increase in costs are likely to be required.

Contingency Plan Requirement. The OPA and several state statutes of similar intent require the majority of the vessels and terminals operated by the Company to maintain approved oil spill contingency plans as a condition of operation. The Company has approved plans that comply with these requirements. The OPA also requires development of regulations for hazardous substance spill contingency plans. The USCG has not yet promulgated these regulations; however, the Company anticipates that they will not be more difficult to comply with than the oil spill plans.

Occupational Health Regulations. The Company’s inspected vessel operations are primarily regulated by the USCG for occupational health standards. Uninspected vessel operations and the Company’s shore personnel are subject to the United States Occupational Safety and Health Administration regulations. The Company believes that it is in compliance with the provisions of the regulations that have been adopted and does not believe that the adoption of any further regulations will impose additional material requirements on the Company. There can be no assurance, however, that claims will not be made against the Company for work related illness or injury, or that the further adoption of health regulations will not adversely affect the Company.
Insurance. The Company’s marine transportation operations are subject to the hazards associated with operating vessels carrying large volumes of bulk cargo in a marine environment. These hazards include the risk of loss of or damage to the Company’s vessels, damage to third parties as a result of collision, fire or explosion, loss or contamination of cargo, personal injury of employees and third parties, and pollution and other environmental damages. The Company maintains insurance coverage against these hazards. Risk of loss of or damage to the Company’s vessels is insured through hull insurance currently insuring approximately $3 billion in hull values. Liabilities such as collision, cargo, environmental, personal injury and general liability are insured up to $1 billion per occurrence.

Environmental Protection. The Company has a number of programs that were implemented to further its commitment to environmental responsibility in its operations. In addition to internal environmental audits, one such program is environmental audits of barge cleaning vendors principally directed at management of cargo residues and barge cleaning wastes. Others are the participation by the Company in the American Waterways Operators Responsible Carrier program and the American Chemistry Council Responsible Care program, both of which are oriented towards continuously reducing the barge industry’s and chemical and petroleum industries’ impact on the environment, including the distribution services area.

Safety. The Company manages its exposure to the hazards associated with its business through safety, training and preventive maintenance efforts. The Company places considerable emphasis on safety through a program oriented toward extensive monitoring of safety performance for the purpose of identifying trends and initiating corrective action, and for the purpose of rewarding personnel achieving superior safety performance. The Company believes that its safety performance consistently places it among the industry leaders as evidenced by what it believes are lower injury frequency and pollution incident levels than many of its competitors.

Training. The Company believes that among the major elements of a successful and productive work force are effective training programs. The Company also believes that training in the proper performance of a job enhances both the safety and quality of the service provided. New technology, regulatory compliance, personnel safety, quality and environmental concerns create additional demands for training. The Company has developed and instituted effective training programs.

Centralized training is provided through the Operations Personnel and Training Department, which is charged with developing, conducting and maintaining training programs for the benefit of all of the Company’s operating entities. It is also responsible for ensuring that training programs are both consistent and effective. The Company’s training facility includes state-of-the-art equipment and instruction aids, including a full bridge wheelhouse simulator, a working towboat, two tank barges and a tank barge simulator for tankermen training. During 2013, approximately 3,375 certificates were issued for the completion of courses at the training facility, of which 1,450 were USCG approved classes and the balance were employee development and Company required classes, including Leadership, Safety by Choice and Defensive Driving.

Quality. Kirby Inland Marine has made a substantial commitment to the implementation, maintenance and improvement of Quality Assurance Systems in compliance with the International Quality Standard, ISO 9001. Kirby Offshore Marine is certified under ABS ISM standards. These Quality Assurance Systems and certification have enabled both shore and vessel personnel to effectively manage the changes which occur in the working environment, as well as enhancing the Company’s safety and environmental performance.

Item 1A. Risk Factors

The following risk factors should be considered carefully when evaluating the Company, as its businesses, results of operations, or financial condition could be materially adversely affected by any of these risks. The following discussion does not attempt to cover factors, such as trends in the United States and global economies or the level of interest rates, among others, that are likely to affect most businesses.

The Inland Waterway infrastructure is aging and may result in increased costs and disruptions to the Company’s marine transportation segment. Maintenance of the United States inland waterway system is vital to the Company’s operations. The system is composed of over 12,000 miles of commercially navigable waterway, supported by over 240 locks and dams designed to provide flood control, maintain pool levels of water in certain areas of the country and facilitate navigation on the inland river system. The United States inland waterway infrastructure is aging, with more than half of the locks over 50 years old. As a result, due to the age of the locks, scheduled and unscheduled maintenance outages may be more frequent in nature, resulting in delays and additional operating expenses. One-half of the cost of new construction and major rehabilitation of locks and dams is paid by marine transportation companies through a 20 cent per gallon diesel fuel tax and the remaining 50% is paid from general federal tax revenues. Failure of the federal government to adequately fund infrastructure maintenance and improvements in the future would have a negative impact on the Company’s ability to deliver products for its customers on a timely basis. In addition, any additional user taxes that may be imposed in the future to fund infrastructure improvements would increase the Company’s operating expenses.

The Company is subject to adverse weather conditions in its marine transportation and diesel engine services segments. The Company’s marine transportation segment is subject to weather conditions on a daily basis. Adverse weather conditions such as high or low water on the inland waterway systems, fog and ice, tropical storms, hurricanes and tsunamis on both the inland waterway systems and throughout the United States coastal waters can impair the operating efficiencies of the marine fleet. Such adverse weather conditions can cause a delay, diversion or postponement of shipments of products and are totally beyond the control of the Company. In addition, adverse water and weather conditions can negatively affect a towing vessel’s performance, tow size, loading drafts, fleet efficiency, place limitations on night passages and dictate horsepower requirements. During 2013, high water on the Mississippi and Illinois Rivers and lock closure issues negatively impacted the 2013 second quarter by an estimated $.03 per share.  During 2012, low water throughout the Mississippi River System negatively impacted the 2012 second, third and fourth quarters, Hurricane Isaac negatively impacted the 2012 third quarter and Hurricane Sandy negatively impacted the 2012 fourth quarter, all by an estimated $.06 to $.07 per share in the aggregate. During the 2011 second quarter, high water and flooding throughout the Mississippi River System and along the Gulf Intracoastal Waterway near Morgan City negatively impacted the quarter by an estimated $.07 per share. The Company’s diesel engine services segment is subject to tropical storms and hurricanes impacting its coastal locations and tornadoes impacting its Oklahoma facilities. The Company’s operations for 2013 and 2011 were not materially affected by hurricanes, tropical storms or tornadoes.

The Company could be adversely impacted by a marine accident or spill event. A marine accident or spill event could close a portion of the inland waterway system or a coastal area of the United States for a period of time. Although statistically marine transportation is the safest means of transporting bulk commodities, accidents do occur, both involving Company equipment and equipment owned by other marine carriers.

The Company transports a wide variety of petrochemicals, black oil, refined petroleum products and agricultural chemicals throughout the Mississippi River System, the Gulf Intracoastal Waterway, coastwise along all three United States coasts and in Alaska and Hawaii. The Company manages its exposure to losses from potential discharges of pollutants through the use of well-maintained and equipped tank barges and towing vessels, through safety, training and environmental programs, and through the Company’s insurance program, but a discharge of pollutants by the Company could have an adverse effect on the Company.
The Company’s marine transportation segment is dependent on its ability to adequately crew its towing vessels. The Company’s towing vessels are crewed with employees who are licensed or certified by the USCG, including its captains, pilots, engineers and tankermen. The success of the Company’s marine transportation segment is dependent on the Company’s ability to adequately crew its towing vessels. As a result, the Company invests significant resources in training its crews and providing crew members an opportunity to advance from a deckhand to the captain of a Company towboat or tugboat, or on the coastal tugboats from a deckhand to the chief engineer. Lifestyle issues are a deterrent for employment for inland and coastal crew members. Inland crew members generally work a 20 days on, 10 days off rotation, or a 30 days on, 15 days off rotation. For the coastal fleet, crew members are generally required to work a 14 days on, 14 days off, 21 days on, 21 days off or 30 days on, 30 days off rotation, dependent upon the location. With the continued high unemployment rates during 2011, 2012 and 2013 associated with the economic recession, crewing levels have remained adequate.

The Company’s marine transportation segment has approximately 3,275 employees, of which approximately 2,425 are vessel crew members. None of the segment’s inland operations are subject to collective bargaining agreements. The segment’s coastal operation includes approximately 875 vessel employees, the majority of whom are subject to collective bargaining agreements in certain geographic areas. Any work stoppages or labor disputes could adversely affect coastal operations in those areas.
 
Reduction in the number of acquisitions made by the Company may curtail future growth. Since 1987, the Company has been successful in the integration of 31 acquisitions in its marine transportation segment and 17 acquisitions in its diesel engine services segment. Acquisitions have played a significant part in the growth of the Company. The Company’s marine transportation revenue in 1987 was $40.2 million compared with $1.7 billion in 2013. Diesel engine services revenue in 1987 was $7.1 million compared with $529.0 million in 2013. While the Company is of the opinion that future acquisition opportunities exist in both its marine transportation and diesel engine services segments, the Company may not be able to continue to grow through acquisitions to the extent that it has in the past.

The Company’s failure to comply with the Foreign Corrupt Practices Act (“FCPA”) could have a negative impact on its ongoing operations. The Company’s operations outside the United States require the Company to comply with a number of United States and international regulations. For example, its operations in countries outside the United States are subject to the FCPA, which prohibits United States companies or their agents and employees from providing anything of value to a foreign official for the purposes of influencing any act or decision of these individuals in their official capacity to help obtain or retain business, direct business to any person or corporate entity, or obtain any unfair advantage. The Company has internal control policies and procedures and has implemented training and compliance programs for its employees and agents with respect to the FCPA. However, the Company’s policies, procedures and programs may not always protect it from reckless or criminal acts committed by its employees or agents, and severe criminal or civil sanctions could be the result of violations of the FCPA. The Company is also subject to the risks that its employees, joint venture partners, and agents outside of the United States may fail to comply with other applicable laws.

The Company’s marine transportation segment is subject to the Jones Act. The Company’s marine transportation segment competes principally in markets subject to the Jones Act, a federal cabotage law that restricts domestic marine transportation in the United States to vessels built and registered in the United States, and manned and owned by United States citizens. The Company presently meets all of the requirements of the Jones Act for its vessels. The loss of Jones Act status could have a significant negative effect on the Company. The requirements that the Company’s vessels be United States built and manned by United States citizens, the crewing requirements and material requirements of the USCG, and the application of United States labor and tax laws increases the cost of United States flag vessels when compared with comparable foreign flag vessels. The Company’s business could be adversely affected if the Jones Act were to be modified so as to permit foreign competition that is not subject to the same United States government imposed burdens. Since the events of September 11, 2001, the United States government has taken steps to increase security of United States ports, coastal waters and inland waterways. The Company feels that it is unlikely that the current cabotage provisions of the Jones Act would be modified or eliminated in the foreseeable future.
The Secretary of Homeland Security is vested with the authority and discretion to waive the Jones Act to such extent and upon such terms as the Secretary may prescribe whenever the Secretary deems that such action is necessary in the interest of national defense. In response to the effects of Hurricanes Katrina and Rita, the Secretary waived the Jones Act generally for the transportation of petroleum products from September 1 to September 19, 2005 and from September 26, 2005 to October 24, 2005. In June 2011, the Secretary waived the Jones Act for the transportation of petroleum released from the Strategic Petroleum Reserve and in November 2012 waived the Jones Act for the transportation of refined petroleum products in the Northeast following Hurricane Sandy. Waivers of the Jones Act, whether in response to natural disasters or otherwise, could result in increased competition from foreign tank vessel operators, which could negatively impact the marine transportation segment.

The Company’s marine transportation segment is subject to regulation by the USCG, federal laws, state laws and certain international conventions, as well as numerous environmental regulations. The majority of the Company’s vessels are subject to inspection by the USCG and carry certificates of inspection. The crews employed by the Company aboard vessels are licensed or certified by the USCG. The Company is required by various governmental agencies to obtain licenses, certificates and permits for its vessels. The Company’s operations are also affected by various United States and state regulations and legislation enacted for protection of the environment. The Company incurs significant expenses to comply with applicable laws and regulations and any significant new regulation or legislation, including climate change laws or regulations, could have an adverse effect on the Company.

The Company is subject to risks associated with possible climate change legislation, regulation and international accords. Greenhouse gas emissions have increasingly become the subject of a large amount of international, national, regional, state and local attention. On December 7, 2009, the United States Environmental Protection Agency (“EPA”) furthered its focus on greenhouse gas emissions when it issued its endangerment finding in response to a decision of the Supreme Court of the United States. The EPA found that the emission of six greenhouse gases, including carbon dioxide (which is emitted from the combustion of fossil fuels), may reasonably be anticipated to endanger public health and welfare. Based on this finding, the EPA defined the mix of these six greenhouse gases to be “air pollution” subject to regulation under the Clean Air Act. Although the EPA has stated a preference that greenhouse gas regulation be based on new federal legislation rather than the existing Clean Air Act, many sources of greenhouse gas emissions may be regulated without the need for further legislation.

The United States Congress has considered in the past legislation that would create an economy-wide “cap-and-trade” system that would establish a limit (or cap) on overall greenhouse gas emissions and create a market for the purchase and sale of emissions permits or “allowances.” Any proposed cap-and-trade legislation would likely affect the chemical industry due to anticipated increases in energy costs as fuel providers pass on the cost of the emissions allowances, which they would be required to obtain under cap-and-trade to cover the emissions from fuel production and the eventual use of fuel by the Company or its energy suppliers. In addition, cap-and-trade proposals would likely increase the cost of energy, including purchases of diesel fuel, steam and electricity, and certain raw materials used or transported by the Company. Proposed domestic and international cap-and-trade systems could materially increase raw material and operating costs of the Company’s customer base. Future environmental regulatory developments related to climate change in the United States that restrict emissions of greenhouse gases could result in financial impacts on the Company’s operations that cannot be predicted with certainty at this time.

The Company’s marine transportation segment is subject to volatility in the United States production of petrochemicals. For 2013, 47% of the marine transportation segment’s revenues were from the movement of petrochemicals, including the movement of raw materials and feedstocks from one refinery or petrochemical plant to another, as well as the movement of more finished products to end users and terminals for export. During 2013, petrochemical volumes continued to improve compared with 2012 and 2011 primarily due to lower priced domestic natural gas that improved the competitiveness of the United States petrochemical industry in global markets, thereby producing increased marine transportation volumes for basic petrochemicals to both domestic consumers and terminals for export destinations. This improvement in volumes was partially offset by the continued generally weak United States economy. Higher natural gas prices and other factors could negatively impact the United States petrochemical industry and its production volumes, which would negatively impact the Company.
The Company’s marine transportation segment could be adversely impacted by the construction of tank barges by its competitors. At the present time, there are an estimated 3,450 inland tank barges in the United States, of which the Company operates 861, or 25%. The number of tank barges peaked at an estimated 4,200 in 1982, slowly declined to 2,750 by 2003, and then gradually increased to an estimated 3,450 by the end of 2013. The Company estimates that 160 tank barges were placed in service during 2011, of which 40 were for the Company, and 125 were retired, 66 of which were the Company’s. During 2012, the Company estimates that 260 tank barges were placed in service, of which 56 were for the Company, and 110 tank barges were retired, 52 of which were the Company’s. During 2013, the Company estimates that 270 tank barges were placed in service, of which 70 were for the Company, and 70 tank barges were retired, 46 of which were the Company’s. The Company estimates that approximately 260 tank barges were ordered during 2013 for delivery throughout 2014, 37 of which are for the Company, and many older tank barges will be retired, dependent on 2014 market conditions. The increase for both 2011, 2012 and 2013, and the orders for 2014, reflect the improved demand for inland petrochemical and black oil barges and federal tax incentives on new equipment in 2011 through 2013. Strong tank barge markets for 2011, 2012 and 2013 absorbed the additional capacity built by the industry.

The risk of an oversupply of inland tank barges may be mitigated by the fact that the inland tank barge industry has a mature fleet. Of the estimated 3,450 tank barges in the industry at the present time, approximately 500 are over 35 years old and approximately 275 of those are over 40 years old. Given the age profile of the industry inland tank barge fleet, the expectation is that older tank barges will continue to be removed from service and replaced by new tank barges that will enter the fleet, with the extent of the retirements dependent on 2014 petrochemical and refinery production levels, crude oil and gas condensate movements and industry-wide tank barge utilization levels.

During 2011 and the first half of 2012, the marine transportation segment was negatively impacted by excess coastal tank barge capacity limiting tank barge utilization to the 75% range. The coastal operations reflected improvements in market conditions during the 2012 second half and throughout 2013, with tank barge utilization improving to the 75% to 80% range in the 2012 third quarter, 85% to 90% in the 2012 fourth quarter, and to the 90% range during 2013. During the 2012 second half and 2013, the Company experienced increased demand for coastal crude and gas condensate moves and success in expanding the coastal customer base to include inland customers with coastal requirements. The Company estimated there are approximately 265 tank barges operating in the 195,000 barrel or less coastal industry fleet, the sector of the market in which the Company operates. The Company believes that very few coastal tank barges were built during 2012 and 2013. The Company announced in January 2014 the signing of an agreement to construct an articulated 185,000 barrel coastal tank barge and 10000 horsepower tugboat unit.  Delivery is anticipated to be in mid-to-late 2015. The Company is aware of several coastal tank barge and tugboat units under construction by competitors for delivery in 2014, 2015 and 2016.
 
Higher fuel prices could increase operating expenses. The cost of fuel during 2013 was approximately 15% of marine transportation revenue. All marine transportation term contracts contain fuel escalation clauses, or the customer pays for the fuel. However, there is generally a 30 to 90 day delay before contracts are adjusted depending on the specific contract. In general, the fuel escalation clauses are effective over the long-term in allowing the Company to adjust to changes in fuel costs due to fuel price changes; however, the short-term effectiveness of the fuel escalation clauses can be affected by a number of factors including, but not limited to, specific terms of the fuel escalation formulas, fuel price volatility, navigating conditions, tow sizes, trip routing, and the location of loading and discharge ports that may result in the Company over or under recovering its fuel costs. Spot contract rates generally reflect current fuel prices at the time the contract is signed but do not have escalators for fuel.

Loss of a large customer or other significant business relationship could adversely affect the Company. Two marine transportation customers, Dow and SeaRiver Maritime, Inc. ("SeaRiver"), the United States transportation affiliate of Exxon Mobil Corporation, accounted for approximately 13% of the Company’s 2013 revenue, 14% of 2012 revenue and 16% of 2011 revenue. The Company has a contract with Dow through 2016 and with SeaRiver through 2017. Although the Company considers its relationships with Dow and SeaRiver to be strong, the loss of either customer could have an adverse effect on the Company.
The Company’s diesel engine services segment has a 48-year relationship with EMD, the largest manufacturer of medium-speed diesel engines. In addition, the Company serves as both an EMD distributor and service center for select markets and locations for both service and parts. Sales and service of EMD products account for approximately 3% of the Company’s revenue for 2013. Although the Company considers its relationship with EMD to be strong, the loss of the EMD distributorship and service rights, or a disruption of the supply of EMD parts, could have a negative impact on the Company’s ability to service its customers.

United has maintained continuous exclusive distribution rights for MTU and Allison since 1946. United is one of MTU’s top five distributors of off-highway engines in North America, with exclusive distribution rights in Oklahoma, Arkansas, Louisiana and Mississippi. In addition, as a distributor of Allison products, United has distribution rights in Oklahoma, Arkansas and Louisiana. United is also the exclusive distributor for Daimler for engines and related equipment in Oklahoma, Arkansas and Louisiana. Sales and service of MTU and Allison products account for approximately 2% and 3%, respectively, of the Company’s revenue during 2013. Although the Company considers its relationships with MTU and Allison to be strong, the loss of MTU, Allison or Daimler distributorships and service rights, or a disruption of the supply of MTU or Allison parts, could have a negative impact on the Company’s ability to service its customers.

The Company is subject to competition in both its marine transportation and diesel engine services segments. The inland and coastal tank barge industry remains very competitive. The Company’s primary competitors are noncaptive inland tank barge operators and coastal operators. The Company also competes with companies who operate refined product and petrochemical pipelines, railroad tank cars and tractor-trailer tank trucks. Increased competition from any significant expansion of or additions to facilities or equipment by the Company’s competitors could have a negative impact on the Company’s results of operations.

The diesel engine services industry is also very competitive. The segment’s primary marine competitors are independent diesel services companies and other factory-authorized distributors, authorized service centers and authorized marine dealers. Certain operators of diesel powered marine equipment also elect to maintain in-house service capabilities. In the power generation market, the primary competitors are other independent service companies. The segment’s land-based market’s principal competitors are independent diesel engine service and oilfield manufacturing companies and other factory-authorized distributors and service centers. In addition, certain oilfield service companies that are customers of the Company also manufacture and service a portion of their own oilfield equipment. Increased competition in the diesel engine services industry and continued low price of natural gas, and resulting decline in drilling for natural gas in North American shale formation, could result in less oilfield equipment being manufactured and remanufactured, lower rates for service and parts pricing and result in less manufacturing, remanufacturing, service and repair opportunities and parts sales for the Company.

Significant increases in the construction cost of tank barges and towboats may limit the Company’s ability to earn an adequate return on its investment in new tank barges and towboats. The price of steel increased significantly from 2006 to 2009, thereby increasing the construction cost of new tank barges and towboats. The Company’s average construction price for a new 30,000 barrel capacity inland tank barge ordered in 2008 for 2009 delivery was approximately 90% higher than in 2000, primarily due to the increase in steel prices. During 2009, the United States and global recession negatively impacted demand levels for inland tank barges and as a result, the construction price of inland tank barges for 2010 delivery fell significantly, primarily due to a significant decrease in steel prices, as well as a decrease in the number of tank barges ordered. The average construction price for tank barges ordered in 2011 for delivery in 2012, ordered in 2012 for delivery in 2013 and ordered in 2013 for delivery in 2014 increased, but remained below the construction price for tank barges built in 2008 and delivered in 2009.

The Company’s marine transportation segment could be adversely impacted by the failure of the Company’s shipyard vendors to deliver new vessels according to contractually agreed delivery schedules and terms.  The Company contracts with shipyards to build new vessels and currently has many vessels under construction.  Construction projects are subject to risks of delay and cost overruns, resulting from shortages of equipment, materials and skilled labor; lack of shipyard availability; unforeseen design and engineering problems; work stoppages; weather interference; unanticipated cost increases; unscheduled delays in the delivery of material and equipment; and financial and other difficulties at shipyards including labor disputes, shipyard insolvency and inability to obtain necessary certifications and approvals.  A significant delay in the construction of new vessels or a shipyard’s inability to perform under the construction contract could negatively impact the Company’s ability to fulfill contract commitments and to realize timely revenues with respect to vessels under construction.  Significant cost overruns or delays for vessels under construction could also adversely affect the Company’s financial condition, results of operations and cash flows.
The Company’s diesel engine services segment could be adversely impacted by future legislation or additional regulation of hydraulic fracturing practices. The Company, through its United subsidiary, is a distributor and service provider of engine and transmission related products for the oil and gas services, power generation and transportation industries, and a manufacturer of oilfield service equipment, including pressure pumping units. The EPA is studying hydraulic fracturing practices, and legislation may be introduced in Congress that would authorize the EPA to impose additional regulations on hydraulic fracturing. In addition, a number of states have adopted or are evaluating the adoption of legislation or regulations governing hydraulic fracturing. Such federal or state legislation and/or regulations could materially impact customers’ operations and greatly reduce or eliminate demand for the Company’s pressure pumping fracturing equipment and related products. The Company is unable to predict whether future legislation or any other regulations will ultimately be enacted and, if so, the impact on the Company’s diesel engine services segment.

The Company’s diesel engine services segment could be adversely impacted by the construction of hydraulic fracturing horsepower by its competitors. At the present time, there is an estimated 18 million horsepower of hydraulic fracturing equipment in North America used in the hydraulic fracturing of shale formations. Increased expansion of, or additions to, facilities or equipment by the Company’s competitors could have a negative impact on the Company’s results of operations. A significant drop in demand as well could result in oversupply in the pressure pumping market as attrition rates may not be high enough to absorb the new capacity entering the market and could negatively impact the Company’s results of operations.

Item 3. Legal Proceedings

In June 2011, the Company as well as three other companies received correspondence from the EPA concerning ongoing cleanup and restoration activities under CERCLA with respect to a Superfund site, the Gulfco Marine Maintenance Site (“Gulfco”), located in Freeport, Texas. In prior years, various subsidiaries of the Company utilized a successor to Gulfco to perform tank barge cleaning services, sand blasting and repair on certain Company vessels. The EPA continues to investigate activities at the site to assess additional Potentially Responsible Parties (“PRPs”). Since 2005, four named PRPs have participated in the investigation, cleanup and restoration of the site under an administrative order from EPA. Information received to date indicates that approximately $4,500,000 has been incurred in connection with the cleanup effort in addition to EPA’s oversight costs of approximately $1,800,000. To date, neither the EPA nor the named PRPs have performed an allocation of potential liability in connection with the site nor have they provided requested supporting documentation for costs and expenses related to the site. The Company is investigating its activities at the site in order to assess what, if any, liability it has in connection with the site.

In 2009, the Company was named a PRP in addition to a group of approximately 250 named PRPs under CERCLA with respect to a Superfund site, the Portland Harbor Superfund site (“Portland Harbor”) in Portland, Oregon. The site was declared a Superfund site in December 2000 as a result of historical heavily industrialized use due to manufacturing, shipbuilding, petroleum storage and distribution, metals salvaging, and electrical power generation activities which led to contamination of Portland Harbor, an urban and industrial reach of the lower Willamette River located immediately downstream of downtown Portland. The Company’s involvement arises from four spills at the site after it was declared a Superfund site, as a result of predecessor entities’ actions in the area. To date, there is no information suggesting the extent of the costs or damages to be claimed from the 250 notified PRPs. Based on the nature of the involvement at the Portland Harbor site, the Company believes its potential contribution is de minimis; however, to date neither the EPA nor the named PRPs have performed an allocation of potential liability in connection with the site nor have they provided costs and expenses in connection with the site.
In 2000, the Company and a group of approximately 45 other companies were notified that they are PRPs under CERCLA with respect to a Superfund site, the Palmer Barge Line Superfund Site (“Palmer”), located in Port Arthur, Texas. In prior years, Palmer had provided tank barge cleaning services to various subsidiaries of the Company. The Company and three other PRPs entered into an agreement with the EPA to perform a remedial investigation and feasibility study and, subsequently, a limited remediation was performed and is now complete. During the 2007 third quarter, five new PRPs entered into an agreement with the EPA related to the Palmer site. In July 2008, the EPA sent a letter to approximately 30 PRPs for the Palmer site, including the Company, indicating that it intends to pursue recovery of $2,949,000 of costs it incurred in relation to the site. The Company and the other PRPs submitted recommended pro rata allocations of costs among all PRPs to the EPA and the U.S. Department of Justice (“DOJ”) in order to resolve the EPA’s past costs claim which is under consideration by the DOJ.

With respect to the above sites, the Company has recorded reserves, if applicable, for its estimated potential liability for its portion of the EPA’s past costs claim based on information developed to date including various factors such as the Company’s liability in proportion to other responsible parties and the extent to which such costs are recoverable from third parties.

On July 25, 2011, a subsidiary of the Company was named as a defendant in the U.S. District Court for the Southern District of Texas - Galveston Division, in a complaint styled Figgs. v. Kirby Inland Marine, et al., which alleges that the plaintiff individually as a vessel tankerman, and on behalf of other current and former similarly situated vessel tankermen employed with the Company, is entitled to overtime pay under the Fair Labor Standards Act. Plaintiffs assert that vessel tankermen are not seamen who are expressly exempt from overtime pay provisions under the law. The case was conditionally certified as a collective action on December 22, 2011 at which time the Court prescribed a notice period for current and former employees to voluntarily participate as plaintiffs. The notice period closed on February 27, 2012. Plaintiffs seek compensatory damages in the form of back pay, attorneys’ fees, cost and liquidated damages. As this matter is in the initial stage of discovery as to the merits of the case, the Company is unable to assess what liability, if any, it may have.
 
In addition, the Company is involved in various legal and other proceedings which are incidental to the conduct of its business, none of which in the opinion of management will have a material effect on the Company’s financial condition, results of operations or cash flows. Management believes that it has recorded adequate reserves and believes that it has adequate insurance coverage or has meritorious defenses for these other claims and contingencies.

For purposes of Management’s Discussion, all net earnings per share attributable to Kirby common stockholders are “diluted earnings per share.” The weighted average number of common shares applicable to diluted earnings per share for 2013, 2012 and 2011 were 56,552,000, 55,674,000 and 54,413,000, respectively. The increase in the weighted average number of common shares for 2013 compared with 2012 and 2011 primarily reflects the issuance of 500,000 shares of Company common stock associated with the December 14, 2012 acquisition of Penn, the issuance of 1,939,234 shares of Company common stock associated with the July 1, 2011 acquisition of K-Sea, the issuance of restricted stock and the exercise of stock options.
Overview

The Company is the nation’s largest domestic tank barge operator, transporting bulk liquid products throughout the Mississippi River System, on the Gulf Intracoastal Waterway, coastwise along all three United States coasts and in Alaska and Hawaii. The Company transports petrochemicals, black oil, refined petroleum products and agricultural chemicals by tank barge. As of December 31, 2013, the Company operated a fleet of 861 inland tank barges with 17.3 million barrels of capacity, and operated an average of 256 inland towboats during 2013. The Company’s coastal fleet consisted of 72 tank barges with 6.0 million barrels of capacity and 76 coastal tugboats. The Company also owns and operates eight offshore barge and tug units transporting dry-bulk commodities in United States coastal trade. Through its diesel engine services segment the Company provides after-market services for medium-speed and high-speed diesel engines, reduction gears and ancillary products for marine and power generation applications, distributes and services high-speed diesel engines and transmissions, pumps and compression products, and manufactures and remanufactures oilfield service equipment, including pressure pumping units, for the land-based pressure pumping and oilfield service markets.

For 2013, net earnings attributable to Kirby were $253,061,000, or $4.44 per share, on revenues of $2,242,195,000, compared with 2012 net earnings attributable to Kirby of $209,438,000, or $3.73 per share, on revenues of $2,112,658,000. The 2013 year results included a credit to selling, general and administrative expenses of $18,300,000 before taxes, or $.20 per share, eliminating the fair value of the contingent earnout liability associated with the April 2011 acquisition of United. This compares with a $4,300,000 before taxes, or $.05 per share, credit to selling, general and administrative expenses for 2012 decreasing the fair value of the contingent earnout liability. The 2013 year included an estimated $.03 per share negative impact during the second quarter from high water on the Mississippi and Illinois Rivers and the closure for repair of the Algiers Lock near New Orleans on the Gulf Intracoastal Waterway, net of certain revenue and cost recovery from contracts with terms that provide reimbursements for delays and increased costs. The 2012 year included an estimated $.06 to $.07 per share negative impact from low water throughout the Mississippi River System during the second, third and fourth quarters, net of certain revenue and cost recovery from contracts with terms that provide reimbursements for delays and increased costs, and the impact of Hurricane Isaac in the second quarter which made landfall near the mouth of the Mississippi River on August 28, 2012 as a category 1 storm, impacting both the marine transportation and diesel engine services segments, and Hurricane Sandy in the fourth quarter which made landfall in the New Jersey area as a category 1 storm, impacting the Northeast marine transportation operations.

Marine Transportation

For 2013, 76% of the Company’s revenue was generated by its marine transportation segment. The segment’s customers include many of the major petrochemical and refining companies that operate in the United States. Products transported include intermediate materials used to produce many of the end products used widely by businesses and consumers — plastics, fiber, paints, detergents, oil additives and paper, among others, as well as residual fuel oil, ship bunkers, asphalt, gasoline, diesel fuel, heating oil, crude oil, gas condensate and agricultural chemicals. Consequently, the Company’s marine transportation business mirrors the volumes produced by the Company’s petroleum, petrochemical and refining customer base. The Company’s marine transportation results include the operations of Allied, acquired on November 1, 2012, and Penn, acquired on December 14, 2012, and described below.

The Company’s marine transportation segment’s revenues for 2013 increased 22% compared with 2012 and operating income for 2013 increased 31% compared with 2012. The higher marine transportation revenues and operating income reflected the acquisitions of Allied and Penn and reflected continued strong demand across all inland marine transportation markets along with continued favorable pricing trends. The Company’s inland petrochemical, black oil and refined petroleum products fleets achieved consistent tank barge utilization levels in the 90% to 95% range throughout 2013.  High water conditions on the Mississippi and Illinois Rivers during the entire 2013 second quarter, and the closure of the Algiers Lock located on the Gulf Intracoastal Waterway due to structural damage during the entire second quarter and through the majority of July created heavy congestion and multi-day delays in the New Orleans area and along the alternate route to the Mississippi River at the Bayou Sorrels and Port Allen Locks. In addition, low water levels on the upper Mississippi River System led to the light loading of tank barges destined for that area during the months of September and October 2013.  During the 2012 second quarter, low water conditions on the Mississippi River System in mid-May and throughout June created delays and increased transit times. The Company’s coastal marine transportation markets continued to improve with tank barge utilization levels in the 90% range throughout 2013, aided by the addition of petrochemical volumes with the acquisition of the Allied fleet and additional black oil volumes with the acquisition of Penn, along with increased transportation of crude oil and gas condensate.
During 2013, approximately 75% of the inland marine transportation revenues were under term contracts and 25% were spot contract revenues, thereby providing the operations with a predictable revenue stream. Inland time charters, which insulate the Company from revenue fluctuations caused by weather and navigational delays and temporary market declines, represented 58% of the inland revenues under term contracts during 2013 compared with 57% during 2012. Rates on inland term contract rates renewed in each of the 2013 quarters increased in the 4% to 6% average range compared with term contracts in the corresponding quarters of 2012. Spot contract rates, which include the cost of fuel, increased modestly in each 2013 quarter compared with the prior quarters. Effective January 1, 2013, annual escalators for labor and the producer price index on a number of inland multi-year contracts resulted in rate increases on those contracts by approximately 1%, excluding fuel.

During 2013, approximately 75% of the coastal marine transportation revenues were under term contracts and 25% were spot contract revenues.  Coastal time charters, which insulate the Company from revenue fluctuations caused by weather and navigational delays and temporary market declines, represented approximately 90% of the coastal revenues under term contracts during 2013.  During 2012, approximately 60% of the coastal marine transportation revenues were under term contracts and 40% were spot contract revenues. Coastal time charters represented approximately 90% of the coastal revenues under term contracts during 2012.  The increase in term contracts reflected stronger demand for coastal tank barges, new contracts with inland customers with coastal tank barge requirements and the 2012 fourth quarter acquisitions of Allied and Penn.  Rates on coastal term contracts renewed throughout 2013 increased in the 7% to 9% average range compared with term contracts in 2012.  Spot contract rates, which include the cost of fuel, continued to improve during 2013 and remained above term contract rates.

The 2013 marine transportation operating margin was 23.8% compared with 22.1% for 2012. The higher operating margin was a reflection of continued high inland utilization, leading to higher inland term and spot contract rates negotiated throughout 2013, as well as higher coastal utilization, including the Allied and Penn equipment, that led to higher coastal term and spot contract rates negotiated throughout 2013.

Diesel Engine Services

During 2013, the diesel engine services segment generated 24% of the Company’s revenue, of which 53% was generated from overhauls and service, 26% from direct parts sales and 21% from manufacturing. The results of the diesel engine services segment are largely influenced by the economic cycles of the marine and power generation markets and the land-based pressure pumping and oilfield services industries.

Diesel engine services revenues for 2013 decreased 25% and operating income decreased 36% compared with 2012. The 2013 operating income included an $18,300,000 credit to selling, general and administrative expenses, resulting from a net decrease in the fair value of the contingent earnout liability associated with the April 2011 acquisition of United, thereby eliminating the remaining liability. This compares with a $4,300,000 credit to selling, general and administrative expenses for 2012, resulting from a net decrease in the fair value of the contingent earnout liability.

The 2013 decreases in revenues and operating income were primarily attributable to a continuation of lower demand for the manufacturing of oil service equipment, including pressure pumping units, and the sale and service of land-based diesel engines, transmissions and parts.  The market for the remanufacturing of older pressure pumping units during 2013 remained relatively stable, but at lower levels. This decline in revenues for 2013 reflected the current state of the pressure pumping market and current oversupply of pressure pumping units, the result of over building in 2011 and of low natural gas prices and corresponding decline in drilling for natural gas in North America. The marine diesel engine services market remained stable, benefiting from major service projects for both inland and coastal customers. The power generation market, consisting of major engine-generator set upgrades and parts sales for both domestic and international power generation customers, was stable.
The diesel engine services operating margin for 2013 was 8.1% compared with 9.4% for 2012. The operating margin for 2013 was positively impacted by the $18,300,000 credit to the contingent earnout liability noted above, while the operating margin for 2012 was positively impacted by the $4,300,000 credit to the contingent earnout liability.

Cash Flow and Capital Expenditures

The Company continued to generate strong operating cash flow during 2013 with net cash provided by operating activities of $601,032,000 compared with $325,730,000 of net cash provided by operating activities for 2012. The 85% increase was primarily from higher net earnings attributable to Kirby, higher depreciation and amortization and a higher deferred tax provision in 2013 versus 2012, as well as a $56,566,000 net increase in cash flows from changes in operating assets and liabilities during 2013 compared to a $124,607,000 net decrease in cash flows from changes in operating assets and liabilities during 2012. In addition, during 2013 and 2012, the Company generated cash of $6,635,000 and $8,932,000, respectively, from the exercise of stock options and $33,982,000 and $19,651,000, respectively, from proceeds from the disposition of assets.

For 2013, cash generated and borrowings under the Company’s revolving credit facility were used for capital expenditures of $253,227,000, including $147,786,000 for inland tank barge and towboat construction and progress payments on the construction of two offshore articulated dry-bulk barge and tugboat units completed in the 2013 second quarter, and $105,441,000 primarily for upgrading the existing marine transportation fleet. The Company’s debt-to-capitalization ratio decreased to 27.0% at December 31, 2013 from 39.9% at December 31, 2012, primarily due to a decrease of $385,960,000 of debt outstanding and the increase in total equity from net earnings attributable to Kirby for 2013 of $253,061,000, exercise of stock options, and the amortization of unearned equity compensation.  As of December 31, 2013, the Company had $41,150,000 outstanding under its revolving credit facility, $208,000,000 outstanding under its term loan and $500,000,000 of senior notes outstanding.

During 2013, the Company took delivery of 70 new inland tank barges with a total capacity of approximately 1,400,000 barrels, retired 46 inland tank barges and returned four leased inland tank barges, reducing its capacity by approximately 800,000 barrels. As a result, the Company added a net 20 inland tank barges and approximately 600,000 barrels of capacity.  The Company’s inland operation also took delivery of three new inland towboats.

The Company projects that capital expenditures for 2014 will be in the $200,000,000 to $210,000,000 range. The 2014 construction program will consist of 37 inland tank barges with a total capacity of 390,000 barrels and progress payments on the construction of a 185,000 barrel coastal articulated tank barge and tugboat unit scheduled to be placed in service in mid-to-late 2015 at a cost of $75,000,000 to $80,000,000. Based on current commitments, steel prices and projected delivery schedules, the Company’s 2014 payments on new inland tank barges will be approximately $45,000,000, and approximately $45,000,000 in  progress payments on the construction of the 185,000 barrel coastal articulated tank barge and tugboat unit. The balance of approximately $110,000,000 to $120,000,000 is primarily capital upgrades and improvements to existing marine equipment, and marine transportation and diesel engine services facilities.

Outlook

Petrochemical and black oil inland tank barge utilization levels remained strong during 2013 in the 90% to 95% range. While the United States economy remains sluggish with consistently high unemployment levels, the United States petrochemical industry continues to see strong production levels for both domestic consumption and exports. Low priced domestic natural gas, a basic feedstock for the United States petrochemical industry, provides the industry with a competitive advantage against foreign petrochemical producers. As a result, United States petrochemical production remained strong throughout 2013, thereby producing increased marine transportation volumes of basic petrochemicals to both domestic consumers and terminals for export destinations. The black oil market also remained strong throughout 2013, primarily due to continued stable United States refinery utilization levels, aided by the export of refined petroleum products and heavy fuel oils, and demand for the inland transportation of crude oil and gas condensate from shale formations in South Texas, as well as the movement of Canadian, Bakken and Utica crude oil and gas condensate from the Midwest to the Gulf Coast.
The United States petrochemical industry is globally competitive based on a number of factors, including a highly integrated and efficient transportation system of pipelines, tank barges, railroads and trucks, largely depreciated yet well maintained and operated facilities, and a low cost feedstock slate, which includes natural gas. Certain United States producers have announced plans for plant capacity expansions and the reopening of idled petrochemical facilities. The current production volumes from the Company’s petrochemical and refinery customers have resulted in the Company’s inland petrochemical, black oil and refined petroleum products tank barge utilization levels in the 90% to 95% range and any increased production from current facilities, plant expansions or the reopening of idled facilities should drive feedstock and production volumes higher, in turn leading to higher tank barge utilization levels and higher term and spot contract pricing, which could be mitigated by additional tank barge capacity.

As of December 31, 2013, the Company estimated there were approximately 3,450 inland tank barges in the industry fleet, of which approximately 500 were over 35 years old and approximately 275 of those were over 40 years old. Given the age profile of the industry inland tank barge fleet, the expectation is that older tank barges will continue to be removed from service and replaced by new tank barges that will enter the fleet. During 2013, with continued strong demand for inland petrochemical and black oil tank barges, the Company estimates that approximately 260 inland tank barges were ordered industry-wide during 2013 and early 2014 for delivery throughout 2014. Historically, 75 to 150 older inland tank barges are retired from service each year, with the extent of the retirements dependent on 2014 petrochemical and refinery production levels, crude oil and gas condensate movements and industry-wide tank barge utilization levels.

During 2011 and the first half of 2012, the marine transportation segment was negatively impacted by excess coastal tank barge capacity limiting tank barge utilization to the 75% range. The coastal operations reflected improvements in market conditions during the 2012 second half and 2013, with tank barge utilization improving to the 75% to 80% range in the 2012 third quarter, 85% to 90% in the 2012 fourth quarter, and to the 90% range throughout 2013.  During 2012 and 2013, the Company experienced increased coastal demand for the movement of crude and gas condensate in the Gulf of Mexico, down the Hudson River to East Coast refineries, and starting in late 2013 from the Columbia River to West Coast refineries.  During 2012 and 2013, the Company was also successful in expanding the coastal customer base to include inland customers with coastal requirements. The acquisitions of Allied and Penn during the 2012 fourth quarter also contributed to the higher 2013 revenue and operating income. As of December 31, 2013, the Company estimated there were approximately 265 tank barges operating in the 195,000 barrel or less coastal industry fleet, the sector of the market in which the Company operates. The Company believes that very few, if any, coastal tank barges in the 195,000 barrel or less category were built during 2012 and 2013.  The Company announced in January 2014 the signing of an agreement to construct an articulated 185,000 barrel coastal tank barge and 10000 horsepower tugboat unit.  Delivery is anticipated to be in mid-to-late 2015.  The Company is aware of several coastal tank barge and tugboat units under construction by competitors for delivery in 2014, 2015 and 2016.
 
In the diesel engine services segment, with the increase in drilling rigs operating in the Gulf of Mexico, positive inland marine transportation markets during 2012 and 2013, and improving coastal marine transportation markets during the 2012 second half and 2013, service activity levels for the marine diesel engine market reflected a modest improvement and should continue to modestly improve as activity increases. The power generation market should remain stable, benefiting from engine-generator set upgrades and parts sales for both domestic and international customers. The land-based diesel engine services market consists of manufacturing and remanufacturing of oilfield service equipment, including pressure pumping units, and the distribution and service of their components, which include high-speed diesel engines, transmissions and pumps, many of the same components used by marine customers. Currently, an estimated 18 million horsepower is employed in the North American pressure pumping business. With the current low price of natural gas, the exploration of United States natural gas shale formations has declined, resulting in excess pressure pumping horsepower. However, with the current high price of crude oil, the exploration of United States crude oil shale formations has remained active. As a result of the excess pressure pumping horsepower in 2012 and 2013, new orders for pressure pumping units essentially stopped and the supply and distribution portion of the land-based market slowed. The Company believes its land-based diesel engine business is at the bottom of the current cycle and it expects improvement in this market sometime in 2014. The Company will continue to manufacture oil service equipment. However, the primary focus for growth in this business, currently as well as into the future, will be on the remanufacturing and service of existing pressure pumping equipment.
Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company evaluates its estimates and assumptions on an ongoing basis based on a combination of historical information and various other assumptions that are believed to be reasonable under the particular circumstances. Actual results may differ from these estimates based on different assumptions or conditions. The Company believes the critical accounting policies that most impact the consolidated financial statements are described below. It is also suggested that the Company’s significant accounting policies, as described in the Company’s financial statements in Note 1, Summary of Significant Accounting Policies, be read in conjunction with this Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Accounts Receivable. The Company extends credit to its customers in the normal course of business. The Company regularly reviews its accounts and estimates the amount of uncollectible receivables each period and establishes an allowance for uncollectible amounts. The amount of the allowance is based on the age of unpaid amounts, information about the current financial strength of customers, and other relevant information. Estimates of uncollectible amounts are revised each period, and changes are recorded in the period they become known. Historically, credit risk with respect to these trade receivables has generally been considered minimal because of the financial strength of the Company’s customers; however, a United States or global recession could impact the collectability of certain customers’ trade receivables which could have a material effect on the Company’s results of operations.

Property, Maintenance and Repairs. Property is recorded at cost. Improvements and betterments are capitalized as incurred. Depreciation is recorded on the straight-line method over the estimated useful lives of the individual assets. When property items are retired, sold or otherwise disposed of, the related cost and accumulated depreciation are removed from the accounts with any gain or loss on the disposition included in the statement of earnings. Maintenance and repairs on vessels built for use on the inland waterways are charged to operating expense as incurred and includes the costs incurred in USCG inspections unless the shipyard extends the life or improves the operating capacity of the vessel which results in the costs being capitalized.  The Company’s ocean-going vessels are subject to regulatory drydocking requirements after certain periods of time to be inspected, have planned major maintenance performed and be recertified by the ABS. These recertifications generally occur twice in a five year period. The Company defers the drydocking expenditures incurred on its ocean-going vessels due to regulatory marine inspections by the ABS and amortizes the costs of the shipyard over the period between drydockings, generally 30 or 60 months, depending on the type of major maintenance performed.  Drydocking expenditures that extend the life or improve the operating capability of the vessel result in the costs being capitalized. Routine repairs and maintenance on ocean-going vessels are expensed as incurred.

The Company reviews long-lived assets for impairment by vessel class whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. Recoverability of the assets is measured by a comparison of the carrying amount of the assets to future net cash expected to be generated by the assets. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. There are many assumptions and estimates underlying the determination of an impairment event or loss, if any. The assumptions and estimates include, but are not limited to, estimated fair market value of the assets and estimated future cash flows expected to be generated by these assets, which are based on additional assumptions such as asset utilization, length of service the asset will be used, and estimated salvage values. Although the Company believes its assumptions and estimates are reasonable, deviations from the assumptions and estimates could produce a materially different result.

Goodwill. The excess of the purchase price over the fair value of identifiable net assets acquired in transactions accounted for as a purchase are included in goodwill. Management monitors the recoverability of goodwill on an annual basis, or whenever events or circumstances indicate that interim impairment testing is necessary. The amount of goodwill impairment, if any, is typically measured based on projected discounted future operating cash flows using a discount rate reflecting the Company’s average weighted cost of capital. The assessment of the recoverability of goodwill will be impacted if estimated future operating cash flows are not achieved. There are many assumptions and estimates underlying the determination of an impairment event or loss, if any. Although the Company believes its assumptions and estimates are reasonable, deviations from the assumptions and estimates could produce a materially different result.
Accrued Insurance. The Company is subject to property damage and casualty risks associated with operating vessels carrying large volumes of bulk liquid and dry cargo in a marine environment. The Company maintains insurance coverage against these risks subject to a deductible, below which the Company is liable. In addition to expensing claims below the deductible amount as incurred, the Company also maintains a reserve for losses that may have occurred but have not been reported to the Company, or are not yet fully developed. The Company uses historic experience and actuarial analysis by outside consultants to estimate an appropriate level of reserves. If the actual number of claims and magnitude were substantially greater than assumed, the required level of reserves for claims incurred but not reported or fully developed could be materially understated. The Company records receivables from its insurers for incurred claims above the Company’s deductible. If the solvency of the insurers became impaired, there could be an adverse impact on the accrued receivables and the availability of insurance.

Acquisitions

On December 28, 2012, the Company purchased the assets of Flag for $6,864,000 in cash. Flag was an East Coast high-speed diesel engine service provider, operating factory-authorized full service marine dealerships for Caterpillar, Cummins, MTU and John Deere diesel engines. Financing of the acquisition was through the Company’s revolving credit facility.

On December 14, 2012, the Company completed the acquisition of Penn, an operator of tank barges and tugboats participating in the coastal transportation of refinery feedstocks, asphalt and crude oil in the United States. The total value of the transaction was $300,538,000, consisting of $146,750,000 of cash, $29,080,000 through the issuance of 500,000 shares of Company common stock valued at $58.16 per share, and $124,708,000 of cash for the retirement of Penn’s debt. Penn’s fleet, comprised of 18 double hull tank barges with a capacity of 1.9 million barrels and 16 tugboats, operated along the East Coast and Gulf Coast of the United States and primarily transported refinery feedstocks, asphalt and crude oil. Financing of the acquisition was through a combination of new senior notes and the issuance of Company common stock.

On November 1, 2012, the Company purchased from Allied 10 coastal tank barges with a total capacity of 680,000 barrels, three offshore dry-bulk barges with a total capacity of 48,000 deadweight tons and seven coastal tugboats for $108,547,000 in cash plus a provision for up to $10,000,000 that will be paid contingent on developments with the sugar provisions in the United States Farm Bill. The fair value of the contingent liability recorded at the acquisition date was $9,756,000. A payment of $5,000,000 was made in the 2013 first quarter on the contingent liability. Allied provided coastal transportation of petrochemicals as well as dry sugar products in the Northeast, Atlantic and Gulf Coast regions of the United States. Financing of the equipment acquisition was through the Company’s revolving credit facility.

On December 15, 2011, the Company completed the purchase of the coastal tank barge fleet of Seaboats, consisting of three 80,000 barrel coastal tank barges and tugboats for $42,745,000 in cash. The three coastal tank barges and tugboats currently operate along the United States East Coast and had an average age of five years. Financing of the equipment acquisition was through the Company’s revolving credit facility.

On July 1, 2011, the Company completed the acquisition of K-Sea, now named Kirby Offshore Marine, an operator of tank barges and tugboats participating in the coastal transportation primarily of refined petroleum products in the United States. The total value of the transaction was $603,427,000, excluding transaction fees, consisting of $227,617,000 of cash paid to K-Sea common and preferred unit holders and the general partner, $262,791,000 of cash to retire K-Sea’s outstanding debt, and $113,019,000 through the issuance of 1,939,234 shares of Company common stock valued at $58.28 per share, the Company’s closing share price on July 1, 2011. The transaction was financed through a combination of the new $540,000,000 term loan and the issuance of Company common stock.

On the acquisition date, Kirby Offshore Marine's fleet, comprised of 57 coastal tank barges with a capacity of 3.8 million barrels and 63 tugboats, operated along the East Coast, West Coast and Gulf Coast of the United States, as well as in Alaska and Hawaii. Kirby Offshore Marine's tank barge fleet, 54 of which were double hulled and had an average age of approximately nine years, is one of the youngest fleets in the coastal trade. Kirby Offshore Marine's customers include major oil companies and refiners, many of which are current Company customers for inland tank barge services. Kirby Offshore Marine has operating facilities in New York, Seattle and Honolulu.
On April 15, 2011, the Company purchased United, a distributor and service provider of engine and transmission related products for the oil and gas services, power generation and transportation industries, and manufacturer of oilfield service equipment. The purchase price was $271,192,000 in cash, plus a three-year earnout provision for up to an additional $50,000,000 payable in 2014, dependent on achieving certain financial targets. As of December 31, 2013, the financial targets were not achieved and no payment will be made. United, headquartered in Oklahoma City, Oklahoma with 21 locations across seven states, distributes and services equipment and parts for Allison, MTU, Daimler, and other diesel and natural gas engines. United also manufactures oilfield service equipment, including hydraulic fracturing equipment. United’s principal customers are oilfield service companies, oil and gas operators and producers, compression companies and on-highway transportation companies. Financing of the acquisition was through the Company’s operating cash flows and borrowings under the Company’s revolving credit facility.

On February 24, 2011, the Company purchased 21 inland and offshore tank barges and 15 inland towboats and offshore tugboats from Enterprise for $53,200,000 in cash. Enterprise provided transportation and delivery services for ship bunkers (engine fuel) to cruise ships, container ships and freighters primarily in the Miami, Port Everglades and Cape Canaveral, Florida area, the three largest cruise ship ports in the United States, as well as Tampa, Florida, Mobile, Alabama and Houston, Texas. Financing of the equipment was through the Company’s operating cash flows.

On February 9, 2011, the Company purchased from Kinder Morgan for $4,050,000 in cash a 51% interest in Kinder Morgan’s shifting operation and fleeting facility for dry cargo barges and tank barges on the Houston Ship Channel. Kinder Morgan retained the remaining 49% interest and the Company will manage the operation. In addition, the Company purchased a towboat from Kinder Morgan for $1,250,000 in cash. Financing of the acquisition was through the Company’s operating cash flows.

The 2013 operating results included a credit to selling, general and administrative expenses of $18,300,000 before taxes, or $.20 per share, eliminating the fair value of the contingent earnout liability associated with the April 2011 acquisition of United. For 2012 and 2011, the operating results included a credit of $4,300,000 before taxes, or $.05 per share, and a charge of $6,300,000, or $.07 per share, respectively, associated with the change in the fair value of the United contingent earnout liability. The 2013 year included an estimated $.03 per share negative impact during the second quarter from high water on the Mississippi and Illinois Rivers and the closure for repair of the Algiers Lock near New Orleans on the Gulf Intracoastal Waterway, net of certain revenue and cost recovery from contracts with terms that provide reimbursements for delays and increased costs. The 2012 year included an estimated $.06 to $.07 per share negative impact from low water throughout the Mississippi River System during the second, third and fourth quarters, net of certain revenue and cost recovery from contracts with terms that provide reimbursements for delays and increased costs, and the impact of Hurricane Isaac in the second quarter which made landfall near the mouth of the Mississippi River on August 28, 2012 as a category 1 storm, impacting both the marine transportation and diesel engine services segments, and Hurricane Sandy in the fourth quarter which made landfall in the New Jersey area as a category 1 storm, impacting the Northeast marine transportation operations.
Marine Transportation

The Company, through its marine transportation segment, is a provider of marine transportation services, operating tank barges and towing vessels transporting bulk liquid products throughout the Mississippi River System, on the Gulf Intracoastal Waterway, coastwise along all three United States coasts and in Alaska and Hawaii. The Company transports petrochemicals, black oil, refined petroleum products and agricultural chemicals by tank barge. As of December 31, 2013, the Company operated 861 inland tank barges, including 44 leased barges, with a total capacity of 17.3 million barrels. This compares with 841 inland tank barges operated as of December 31, 2012, including 49 leased barges, with a total capacity of 16.7 million barrels. The Company operated an average of 256 inland towboats during 2013, of which an average of 77 were chartered, compared with 245 during 2012, of which an average of 64 were chartered. The Company’s coastal tank barge fleet as of December 31, 2013 consisted of 72 tank barges, one of which was single hull and 11 of which were leased, with 6.0 million barrels of capacity, and 76 tugboats, seven of which were chartered. This compares with 81 coastal tank barges operated as of December 31, 2012, two of which were single hull and 12 of which were leased, with 6.3 million barrels of capacity, and 86 coastal tugboats, three of which were chartered. As of December 31, 2013 and 2012, the Company operated eight offshore dry-bulk barge and tugboat units, of which one of the tugboats was chartered in 2012, engaged in the offshore transportation of dry-bulk cargoes. The Company also owns a two-thirds interest in Osprey which transports project cargoes and cargo containers by barge, as well as a 51% interest in a shifting operation and fleeting facility for dry cargo barges and tank barges on the Houston Ship Channel.

2013 Compared with 2012

Marine Transportation Revenues

Marine transportation revenues for 2013 increased 22% when compared with 2012, reflecting the expansion of the coastal transportation business with the acquisition of Allied on November 1, 2012 and Penn on December 14, 2012. The inland tank barge fleet contributed approximately 70% and the coastal fleet approximately 30% of 2013 marine transportation revenues. Equipment utilization during 2013 for the inland petrochemical, black oil and refined petroleum products fleets remained in the 90% to 95% range, consistent with 2012.  The coastal equipment utilization for 2013 was in the 90% range, a major improvement over the 80% range reported for 2012.

The petrochemical market, the Company’s largest market, contributed 47% of marine transportation revenues for 2013, reflecting continued strong volumes from Gulf Coast petrochemical plants for both domestic consumers and to terminals for export destinations. Low priced domestic natural gas, a basic feedstock for the United States petrochemical industry, provides the industry with a competitive advantage against foreign petrochemical producers. The 2013 year also included a full year of revenues from the 10 coastal tank barges purchased from Allied that transport petrochemicals coastwise.

The black oil market, which contributed 25% of marine transportation revenues for 2013, also reflected continued strong demand, driven by steady refinery production levels, the export of refined petroleum products and fuel oils, and increased demand for crude oil transportation from the Eagle Ford shale formations in South Texas both along the Gulf Intracoastal Waterway with inland vessels and in the Gulf of Mexico with coastal equipment, and for the movement of Canadian, Bakken and Utica crude oil and gas condensate downriver from the Midwest to the Gulf Coast. The coastal fleet also moved Bakken crude from Albany, New York to Northeast refineries during 2013 and in the 2013 fourth quarter began moving Bakken crude from the Columbia River to West Coast refineries. The 2013 year also included a full year of revenues from the 18 coastal tank barges acquired with the acquisition of Penn, expanding the Company’s coastal black oil movements of refinery feedstocks, asphalt, crude oil and gas condensate. 

The refined petroleum products market, which contributed 24% of marine transportation revenues for 2013, reflected higher demand for the movement of products in the inland and coastal markets, benefiting from additional volumes from major customers and aided by the export of refined petroleum products and heavy fuel oils. The coastal refined products market was also driven by continued success in expanding the coastal customer base to inland customers with coastal requirements, as well as a colder winter in the Northeast that increased the demand for distillate products.

The agricultural chemical market, which contributed 4% of 2013 marine transportation revenues, saw weak demand during January and February due to winter weather and low water conditions in the Midwest. Demand increased significantly in March for both domestically produced and imported products and continued throughout the second quarter.  Demand decreased during the 2013 third quarter due to seasonality and the Midwest drought but improved during the fourth quarter with the traditional fall fill.

For 2013, the inland operations incurred 7,843 delay days, 23% more than the 6,358 delay days that occurred during 2012. Delay days measure the lost time incurred by a tow (towboat and one or more tank barges) during transit when the tow is stopped due to weather, lock conditions or other navigational factors. High water conditions on the Mississippi and Illinois Rivers during the entire 2013 second quarter, and the closure of the Algiers Lock located on the Gulf Intracoastal Waterway due to structural damage during the entire second quarter and through the majority of July, created heavy congestion and multi-day delays in the New Orleans area and along the alternate route to the Mississippi River at the Bayou Sorrels and Port Allen Locks. In addition, low water levels on the upper Mississippi River System led to the light loading of tank barges destined for that area during the months of September and October 2013.
During 2013 and 2012, approximately 75% of marine transportation’s inland revenues were under term contracts and 25% were spot contract revenues. Inland time charters, which insulate the Company from revenue fluctuations caused by weather and navigational delays and temporary market declines, represented 58% of the revenues under term contracts during 2013 compared with 57% during 2012. The 75% term contract and 25% spot contract mix provides the inland operations with a predictable revenue stream.

During 2013, approximately 75% of the coastal revenues were under term contracts and 25% were spot contract revenues. Coastal time charters represented approximately 90% of the revenues under term contracts. For 2012, approximately 60% of the coastal revenues were under term contracts and 40% were spot contract revenues. The increase in term contracts reflected the stronger demand for coastal tank barges, as well as the 2012 fourth quarter acquisitions of Allied and Penn.

Rates on inland term contracts renewed throughout 2013 increased in the 4% to 6% average range compared with term contracts renewed throughout 2012. Spot contract rates in 2013, which include the cost of fuel, increased modestly compared with 2012. Effective January 1, 2013, annual escalators for labor and the producer price index on a number of inland multi-year contracts resulted in rate increases on those contracts of approximately 1%, excluding fuel.

Rates on coastal term contracts renewed throughout 2013 increased in the 7% to 9% average range compared with term contracts renewed throughout 2012.  Spot contract rates, which include the cost of fuel, continued to improve during 2013 and remained above term contract rates.

Marine Transportation Costs and Expenses

Costs and expenses for 2013 increased 19% compared with the 2012, reflecting higher costs and expenses associated with increased marine transportation demand, and to a lesser extent the Allied and Penn acquisitions in late 2012. Costs of sales and operating expenses for 2013 increased 21% compared with 2012.

The inland operations operated an average of 256 towboats during 2013, of which an average of 77 were chartered, compared with 245 during 2012, of which an average of 64 were chartered. The increase in the number of towboats operated was a reflection of the higher tank barge utilization levels in the petrochemical, black oil and refined petroleum products markets during 2013 compared with 2012, as well as higher demand for towboats associated with the high water and lock closure issues noted above. As demand increases or decreases, or as weather or water conditions dictate, the Company charters-in or releases chartered towboats in an effort to balance horsepower needs with current requirements. The Company has historically used chartered towboats for approximately one-third of its inland horsepower requirements.

During 2013, the inland operations consumed 43.3 million gallons of diesel fuel compared to 43.1 million gallons consumed during 2012. The average price per gallon of diesel fuel consumed during 2013 was $3.21 compared with $3.24 for 2012. Fuel escalation and de-escalation clauses on term contracts are designed to rebate fuel costs when prices decline and recover additional fuel costs when fuel prices rise; however, there is generally a 30 to 90 day delay before the contracts are adjusted. Spot contracts do not have escalators for fuel.

Selling, general and administrative expenses for 2013 increased 6% compared with 2012, reflecting the acquisitions of Allied and Penn, and 2013 severance charges of $370,000 associated with the integration of Penn's administrative functions into the Company. The 2012 year included $2,920,000 of severance charges associated with the integration of Kirby Offshore Marine’s administrative functions into the Company.

Depreciation and amortization for 2013 increased 15% compared with 2012.  The increase was primarily attributable to increased capital expenditures, including new inland tank barges and towboats, and the acquisitions of Allied and Penn during late 2012.

        Marine Transportation Operating Income and Operating Margins

Marine transportation operating income for 2013 increased 31% compared with 2012. The operating margin was 23.8% for 2013 compared with 22.1% for 2012. The higher operating income and operating margin was a reflection of continued high inland equipment utilization, leading to higher inland term and spot contract rates negotiated throughout 2012 and 2013, as well as higher coastal equipment utilization, including the Allied and Penn equipment, that led to higher coastal term and spot contract rates negotiated throughout 2013.
2012 Compared with 2011

Marine Transportation Revenues

Marine transportation revenues for 2012 increased 18% compared with 2011, reflecting the expansion into the coastal transportation business with the acquisition of Kirby Offshore Marine on July 1, 2011, the acquisition of the marine transportation fleet of Allied on November 1, 2012 and the acquisition of Penn on December 14, 2012. The coastal tank barge fleet contributed approximately 21% of the 2012 and 11% of 2011 marine transportation revenues. The increase also reflected strong United States petrochemical production levels and stable refinery production levels, resulting in equipment utilization levels in the 90% to 95% range for the inland petrochemical and black oil fleets, as well as favorable term and spot contract pricing. In addition, average diesel fuel prices for 2012 increased 5% compared with 2011, positively impacting marine transportation revenues since fuel price increases are covered by fuel escalation and de-escalation clauses in the Company’s term contracts, or the customer pays for the fuel.

During the 2012 third quarter, the inland operations experienced low water conditions throughout the Mississippi River System. During the 2012 fourth quarter, conditions deteriorated between St. Louis, Missouri and Cairo, Illinois, as well as on the Illinois River; however, water levels improved late in the fourth quarter on the lower Mississippi and Ohio Rivers. The low water conditions required a reduction in tow sizes, slower transit times and draft reductions on tank barges with Mississippi River destinations all resulting in lower revenues. Water levels on the Gulf Intracoastal Waterway remained at normal levels and were not impacted by the low water levels on the Mississippi River System. The 2012 third quarter was negatively impacted by Hurricane Isaac which made landfall at the mouth of the Mississippi River on August 28, 2012 as a category 1 storm, impacting both the inland and coastal transportation operations and Gulf Coast diesel engine services operations. The 2012 fourth quarter was negatively impacted by Hurricane Sandy which made landfall near Atlantic City, New Jersey as a category 1 storm, impacting coastal operations along the Atlantic Seaboard and New York harbor. The Company estimates that the low water and Hurricane Isaac negatively impacted the 2012 third quarter by an estimated $.03 to $.04 per share. The Company estimates that the low water and Hurricane Sandy negatively impacted the 2012 fourth quarter by an estimated $.02 to $.03 per share.

The petrochemical market, the Company’s largest market, contributed 51% of the marine transportation revenues for 2012, reflecting continued strong business levels. Low-priced natural gas, a basic feedstock for the United States petrochemical industry, provided the industry with a competitive advantage over foreign petrochemical producers. As a result, United States petrochemical production remained strong during 2012, producing stable marine transportation volumes for the movement of basic petrochemicals for both domestic consumers and terminals for foreign destinations. The Company entered the coastal petrochemical market with the acquisition of Allied on November 1, 2012.

The refined petroleum products market, which contributed 26% of 2012 marine transportation revenues, reflected higher demand for the movement of products in the inland market, benefiting from additional volumes from major customers. The coastal refined products market saw overall equipment utilizations in the 75% to 80% range for the majority of 2012, with demand increasing in the 2012 fourth quarter.

The black oil market, which contributed 19% of 2012 marine transportation revenues, also reflected stronger demand, driven by steady refinery production levels, the export of heavy fuel oil, demand for crude oil transportation from the Eagle Ford shale formations in South Texas both along the Gulf Intracoastal Waterway and in the Gulf of Mexico, and for the movement of Canadian and Bakken crude downriver from the Midwest to the Gulf Coast. The coastal fleet also moved Bakken crude from Albany, New York to Northeast refineries during the 2012 second half. With the acquisition on December 14, 2012 of Penn, the Company expanded its coastal black oil movements, including refinery feedstocks, asphalt and crude oil.

The agricultural chemical market, which contributed 4% of 2012 marine transportation revenues, saw the traditional spring fill start early in the first quarter and continue through April and May. The traditional fall fill started early in July and continued through September with the movement of both domestically produced and imported products, driven by low fertilizer inventories. The low water levels and the Midwest drought negatively impacted demand during the 2012 fourth quarter.
The coastal marine transportation operations reflected improvements in market conditions during the 2012 second half, with tank barge utilization improving to the 75% to 80% range in the third quarter and 85% to 90% in the fourth quarter, and some days higher, compared with 75% for the 2012 first six months. During the 2012 second half, and particularly the fourth quarter, the coastal market experienced increased demand for crude and condensates moves, as well as success in expanding the coastal customer base to inland customers with coastal requirements. The acquisitions of Allied and Penn during the 2012 fourth quarter also contributed to the higher revenues and operating income, more than offsetting the additional interest expense and transaction fees incurred.

For 2012, the inland operations of the marine transportation segment incurred 6,358 delay days, 6% less than the 6,777 delay days that occurred during 2011. Delay days measure the lost time incurred by a tow (towboat and one or more tank barges) during transit when the tow is stopped due to weather, lock conditions and other navigational factors. Low water conditions on the Mississippi River System, starting in mid-May 2012, and continuing through the remainder to the year, created delays. Hurricane Isaac also created delays in the 2012 third quarter. For the 2012 first quarter, weather and water conditions in the Midwest were better compared with the first quarter of 2011, but fog and high winds along the Gulf Coast during the 2012 first quarter created delays days in excess of the 2011 first quarter. Lock repairs on the Gulf Intracoastal Waterway and the Ohio River during the 2012 first and second quarters also created delays. During the 2012 fourth quarter, low water levels on the Mississippi River between Cairo, Illinois and St. Louis, Missouri, as well as on the Illinois River, caused delays.

During 2012, approximately 75% of inland marine transportation revenues were under term contracts and 25% were spot contract revenues. Inland operations time charters, which insulate the Company from revenue fluctuations caused by weather and navigational delays and temporary market declines, represented 57% of the revenues under term contracts during 2012 compared with 55% during 2011. The 75% term contract and 25% spot contract mix provides the inland operations with a predictable revenue stream.

During 2012, approximately 60% of the coastal marine transportation revenues were under term contracts and 40% were spot contract revenues. As of December 31, 2012, with the acquisitions of Allied and Penn, along with stronger demand for coastal tank barges, approximately 70% of the coastal revenues were under term contracts. Coastal time charters represented approximately 90% of the revenues under term contracts during 2012.

Inland operations term contracts renewed throughout 2012 increased in the 4% to 6% average range compared with term contracts renewed throughout 2011. Spot contracts throughout 2012, which include the cost of fuel, increased modestly compared with 2011. Effective January 1, 2012, annual escalators for labor and the producer price index on a number of inland operations multi-year contracts resulted in rate increases on those contracts in the 2% range, excluding fuel.

For the coastal operations, term contracts renewed in the 2012 first six months were relatively stable compared with contract rates in the 2011 first six months. No term contracts were renewed in the 2012 third quarter. Contracts renewed in the 2012 fourth quarter increased in the 7% to 9% average range compared with the 2011 fourth quarter. Spot contract rates for the 2012 first and second quarter were relatively stable compared with the corresponding prior quarter. Spot contract rates for the 2012 third quarter improved in the 2% to 4% average range compared with the 2012 second quarter, while spot contract rates for the 2012 fourth quarter increased in the 5% to 9% average range compared with the 2012 third quarter.

Marine Transportation Costs and Expenses

Costs and expenses, as well as costs of sales and operating expenses, for 2012 increased 18% compared with 2011, reflecting the Kirby Offshore Marine acquisition effective July 1, 2011, and to a lesser extent the Allied and Penn acquisitions in late 2012, as well as higher costs and expenses associated with increased inland marine transportation demand and higher diesel fuel prices.
The inland operations of the marine transportation segment operated an average of 245 towboats during 2012, of which an average of 64 were chartered, compared with 240 during 2011, of which an average of 61 were chartered. As demand increases or decreases, or as weather or water conditions dictate, the Company charters-in or releases chartered towboats in an effort to balance horsepower needs with current requirements. The Company has historically used chartered towboats for approximately one-third of its horsepower requirements.

During 2012, the inland operations of the marine transportation segment consumed 43.1 million gallons of diesel fuel compared to 44.8 million gallons consumed during 2011. The average price per gallon of diesel fuel consumed during 2012 was $3.24, an increase of 5% compared with $3.08 per gallon for 2011. Fuel escalation and de-escalation clauses are designed to rebate fuel costs when prices decline and recover additional fuel costs when fuel prices rise; however, there is generally a 30 to 90 day delay before the contracts are adjusted. Spot contracts do not have escalators for fuel.

Selling, general and administrative expenses for 2012 increased 16% compared with 2011, primarily reflecting the acquisition of Kirby Offshore Marine effective July 1, 2011 and a $2,421,000 first quarter of 2012 and $499,000 second quarter of 2012 severance charge associated with the integration of Kirby Offshore Marine’s administrative functions into the Company, and to a lesser extent the acquisitions of Allied and Penn during late 2012.

Depreciation and amortization for 2012 increased 17% compared with 2011, primarily attributable to the acquisitions of Kirby Offshore Marine and Seaboats during 2011, and to a lesser extent the acquisitions of Allied and Penn during late 2012.

Marine Transportation Operating Income and Operating Margins

The marine transportation operating income for 2012 increased 19% compared with 2011. The higher operating income was primarily a reflection of higher inland tank barge utilization, higher inland term and spot contract rates negotiated throughout 2012, and the operating income from Kirby Offshore Marine, Allied and Penn, partially offset by the negative impact of low water conditions and Hurricanes Isaac and Sandy as noted above. The Company estimates that Allied and Penn contributed $.03 per share to 2012 earnings, more than offsetting the additional interest expense and transaction fees incurred with the acquisitions. The 2012 operating margin was 22.1% compared with 21.9% for 2011. The slight improvement was primarily a reflection of higher inland tank barge utilization and higher inland term and spot contract rates negotiated throughout 2012, partially offset by a lower but improved operating margin for the coastal operations.

Diesel Engine Services

The Company, through its diesel engine services segment, sells genuine replacement parts, provides service mechanics to overhaul and repair medium-speed and high-speed diesel engines, transmissions, reduction gears, pumps and compression products, maintains facilities to rebuild component parts or entire medium-speed and high-speed diesel engines, transmissions and entire reduction gears, and manufactures and remanufactures oilfield service equipment, including pressure pumping units. The Company primarily services the marine, power generation and land-based oil and gas operator and producer markets.

2013 Compared with 2012
 
Diesel Engine Services Revenues
 
Diesel engine services revenues for 2013 decreased 25% compared with 2012, primarily attributable to a continuation of lower demand for the manufacturing of oil service equipment and the sale and service of land-based diesel engines, transmissions and parts.  The market for the remanufacturing of older pressure pumping units remained relatively stable, but at lower levels. This decline in revenues for 2013 reflected the current state of the pressure pumping market and current oversupply of pressure pumping units, the result of over building in 2011 and of low natural gas prices and corresponding decline in drilling for natural gas in North America. The marine diesel engine services market remained stable, benefiting from major service projects for Midwest and Gulf Coast inland customers, and East Coast, Gulf Coast and West Coast offshore customers.   The power generation market, consisting of major engine-generator set upgrades and parts sales for both domestic and international power generation customers, was stable.

Diesel Engine Services Costs and Expenses

Costs and expenses for 2013 decreased 24% compared with 2012 and costs of sales and operating expenses decreased 25%, corresponding with the decrease in land-based revenues noted above. Selling, general and administrative expenses for 2013 decreased 14% compared with 2012, as 2013 included an $18,300,000 credit resulting from a decrease in the fair value of the contingent earnout liability associated with the April 2011 acquisition of United, thereby eliminating the remaining liability. This compares with a $4,300,000 credit for 2012 resulting from a net decrease in the fair value of the contingent earnout liability.  The 2013 year also included a reduction in force charge in the marine high-speed sector, as well as higher warranty reserves and certain employee related costs in the land-based sector related to personnel changes.

Diesel Engine Services Operating Income and Operating Margins

Diesel engine services operating income for 2013 decreased 36% compared with 2012.  The operating margin for 2013 was 8.1% compared with 9.4% for 2012.  The lower operating income and operating margin primarily reflected the significant reduction in the number of pressure pumping units manufactured and the decline in the sale and service of land-based diesel engines, transmissions and parts during 2013 compared with 2012. In addition, 2013 and 2012 included the $18,300,000 and $4,300,000, respectively, earnout credit noted above.

2012 Compared with 2011

Diesel Engine Services Revenues

Diesel engine services revenue for 2012 increased 7% compared with 2011, reflecting the acquisition of United on April 15, 2011, a strong 2012 first quarter land-based market that benefited from the manufacture and remanufacture of pressure pumping units, as well as favorable sales and service of diesel engines and transmissions. The second, third and fourth quarters of 2012 reflected the curtailment of land-based demand for the manufacturing of pressure pumping units, as well as a decline in service of land-based diesel engines and sales of diesel engines, transmissions and parts, primarily associated with the current low price of natural gas and resulting decline in drilling for natural gas in North American shale formations. Partially offsetting the decline in the manufacturing of pressure pumping units was the continued demand for the manufacturing of blenders, pumpers, cementers and fire pumps, as well as an increase in the number of pressure pumping units to be remanufactured. The segment experienced higher marine engine service work for oil service customers as the Gulf of Mexico oil and gas drilling activity increased, partially offset by weakness in the 2012 second half in the Midwest and Gulf Coast marine markets with the deferral of large engine overhaul projects driven by the low water issues on the Mississippi River and Hurricane Isaac during the 2012 third quarter. Revenue from the power generation market was consistent with 2011 for engine-generator set upgrades and parts sales for both domestic and international customers.
Diesel Engine Services Costs and Expenses

Costs and expenses for 2012 increased 8% compared with 2011, corresponding with the increases and decreases in revenues noted above. The increase in each cost and expense category, except selling, general and administrative, was primarily attributable to the United acquisition. In addition, start-up costs associated with a new marine power distribution agreement and a new engine certification in the power generation market also increased costs. Selling, general and administrative expense decreased 2%, reflecting a $4,300,000 credit resulting from a net decrease in the fair value of the contingent earnout liability associated with the April 2011 acquisition of United. This compares with a charge to selling, general and administrative expense for 2011 of $6,300,000 resulting from a net increase in the fair value of the contingent earnout liability.

Diesel Engine Services Operating Income and Operating Margins

Operating income for the diesel engine services segment for 2012 decreased 3% compared with 2011, reflecting the April 15, 2011 acquisition of United, the significant reduction in the number of pressure pumping units manufactured by United and decline in United’s service of land-based diesel engines and sales transmission and parts during 2012 versus 2011. This decline was partially offset by an increase in the remanufacturing of older pressure pumping units, the manufacturing of other land-based equipment and higher operating results from the marine market. The operating margin for 2012 was 9.4% compared with 10.4% for 2011. The lower operating margin for 2012 primarily reflected the weaker land-based oil services market.

General Corporate Expenses

General corporate expenses for 2013, 2012 and 2011 were $15,728,000, $13,294,000 and $17,915,000, respectively. The 18% increase for 2013 compared with 2012 was primarily due to higher employee incentive compensation accruals, employee recruiting costs, and additional corporate personnel and related costs to support the Allied and Penn acquisitions.  The 26% decrease for 2012 compared with 2011 reflected higher 2011 legal, investment banking and transactions fees associated with the 2011 acquisitions described above.

Gain (Loss) on Disposition of Assets

The Company reported a net gain on disposition of assets of $888,000 in 2013 compared with a net loss on disposition of assets of $14,000 in 2012 and $40,000 in 2011. The net gains and losses were predominantly from the sale or retirement of marine equipment and the sale of a diesel engine services facility in 2013.

Equity in Earnings of Affiliates

Equity in earnings of affiliates consisted of the Company’s 50% ownership of a barge fleeting operation.

Noncontrolling Interests

Noncontrolling interests for 2013 increased 2% compared with 2012 and increased 29% for 2012 compared with 2011, primarily the result of the purchase in February 2011 of a 51% interest in Kinder Morgan’s shifting operation and fleeting facility for dry cargo barges and tank barges on the Houston Ship Channel and the increase in the demand for the facility since the date of acquisition. Kinder Morgan retained the remaining 49% interest.

Interest Expense

Interest expense for 2013 increased 14% compared with 2012, primarily the result of borrowings under the revolving credit facility to finance the November 2012 Allied acquisition, as well as the new senior notes to finance the December 2012 Penn acquisition.  Interest expense for 2012 increased 36% compared with 2011, primarily the result of borrowing under the revolving credit facility to finance the April 2011 United acquisition and the November 2012 Allied acquisition, as well as the $540,000,000 term loan to finance the July 2011 K-Sea acquisition. During 2013, 2012 and 2011, the average debt and average interest rate, including the effect of interest rate swaps in 2012 and 2011, were $974,012,000 and 2.8%, $800,123,000 and 3.0%, and $518,303,000 and 3.4%, respectively.

2013 Compared with 2012

Current assets as of December 31, 2013 decreased 9% compared with December 31, 2012. Trade accounts receivable decreased 1%, primarily a reflection of better collection efforts.   Inventory in the diesel engine services segment decreased 23%, primarily due to a reduction in the number of engines and transmissions on hand at the Company’s land-based diesel engine service facilities that were purchased in 2012 for specific customers and sold in 2013, and the sale of pressure pumping units held on hand.

Property and equipment, net of accumulated depreciation, at December 31, 2013 increased 2% compared with December 31, 2012. The increase reflected $253,227,000 of capital expenditures for 2013, more fully described under Capital Expenditures below, less $155,068,000 of depreciation expense for 2013 and $32,798,000 of property disposals during 2013.

Other assets at December 31, 2013 increased 21% compared with December 31, 2012 primarily due to deferred major maintenance dry-dock expenditures on ocean-going vessels during 2013 and the recording of a pension asset of $4,563,000 due to the Company’s pension plan being in a fully funded position at December 31, 2013.

Current liabilities as of December 31, 2013 decreased 3% compared with December 31, 2012.  At December 31, 2013, none of the long-term debt was classified as current due to prepayments of the term loan during 2013, compared with $65,000,000 classified as current portion of long-term debt at December 31, 2012. Accounts payable increased 13% primarily from higher voyage expenditures associated with higher marine transportation activity levels and higher shipyard accruals.  Accrued liabilities increased 13% primarily from higher employee incentive compensation accruals, accrued interest and marine insurance claim reserves. Deferred revenues increased 118%, primarily reflecting increased advanced billings for coastal transportation customers.

Long-term debt, less current portion, as of December 31, 2013 decreased 30% compared with December 31, 2012, reflecting payments on the revolving credit facility and term loan during 2013.

Deferred income taxes as of December 31, 2013 increased 28% compared with December 31, 2012. The increase was primarily due to the 2013 deferred tax provision of $103,056,000, the result of bonus tax depreciation on qualifying expenditures due to the American Taxpayers Relief Act of 2012 that provides 50% bonus tax depreciation for capital investments placed in service through December 31, 2013.

Other long-term liabilities as of December 31, 2013 decreased 78% compared with December 31, 2012. The decrease was due to the reversal of pension plan accruals of $49,100,000 as the Company’s pension plan was fully funded at December 31, 2013, the reversal during 2013 of the $18,300,000 contingent earnout liability associated with the acquisition of United, and a $5,000,000 payment associated with the $10,000,000 contingent liability recorded at the acquisition date of Allied pertaining to developments with the sugar provisions in the United States Farm Bill.

Total equity as of December 31, 2013 increased 18% compared with December 31, 2012. The increase was primarily the result of $253,061,000 of net earnings attributable to Kirby for 2013, a $5,493,000 decrease in treasury stock, a $12,830,000 increase in additional paid-in capital and a $44,334,000 increase in accumulated other comprehensive income ("OCI"). The decrease in treasury stock was attributable to the exercise of stock options and the issuance of restricted stock. The increase in additional paid-in capital was due to the excess of proceeds received upon exercise of stock options and the issuance of restricted stock over the cost of the treasury stock issued. The increase in accumulated OCI primarily resulted from the net change in fair value of interest rate swap agreements, net of taxes, more fully described under Fair Value of Derivative Instruments below, and the decrease in unrecognized losses related to the Company’s defined benefit plans.

2012 Compared with 2011

Current assets as of December 31, 2012 increased 13% compared with current assets as of December 31, 2011. Trade accounts receivable increased 3%, primarily reflecting the acquisitions of Allied and Penn, partially offset by lower trade receivables from the land-based diesel engine services market due to a decline in business activity levels. Inventory increased 36%, primarily reflecting the decrease in land-based diesel engine service activity levels, as well as the purchase of engines and transmissions to be sold to specific customers in 2013.
Property and equipment, net of accumulated depreciation, at December 31, 2012 increased 27% compared with December 31, 2011. The increase reflected $312,167,000 of capital expenditures for 2012, more fully described under Capital Expenditures below, the fair value of the property and equipment acquired in the Allied and Penn acquisitions of $334,819,000, less $136,701,000 of depreciation expense for 2012 and $18,717,000 of property disposals during 2012.

Goodwill as of December 31, 2012 increased 23% compared with December 31, 2011, predominately reflecting the goodwill recorded in the Allied, Penn and Flag acquisitions.

Other assets as of December 31, 2012 increased 18% compared with December 31, 2011, primarily reflecting other assets acquired in the Allied, Penn and Flag acquisitions, including intangible assets other than goodwill.

Current liabilities as of December 31, 2012 decreased 1% compared with December 31, 2011. The current portion of long-term debt as of December 31, 2012 reflected the reclassification of an additional $26,000,000 of the term loan as current. Accounts payable decreased 1%, primarily from the decrease in business activity levels in the land-based diesel engine services market, partially offset by the Penn acquisition. Accrued liabilities decreased 3%, primarily reflecting lower incentive compensation accruals. Deferred revenues decreased 57%, primarily reflecting reduced deposits received from customers for the construction of new oilfield service equipment in the land-based diesel engine services market.

Long-term debt, less current portion, as of December 31, 2012 increased 40% compared with December 31, 2011, primarily reflecting the borrowings under the Company’s revolving credit facility in November 2012 to finance the Allied acquisition and the $275,000,000 drawn down under the new $500,000,000 note purchase agreement in December 2012 to finance the Penn acquisition, less payments on the revolving credit facility and the term loan during 2012.

Deferred income taxes as of December 31, 2012 increased 46% compared with December 31, 2011. The increase was primarily due to the recording of $59,020,000 of deferred income taxes with the Penn acquisition on December 14, 2012 and the 2012 deferred income tax provision of $77,005,000. The deferred tax provision was primarily due to bonus tax depreciation on qualifying expenditures due to the Tax Relief Act that provided 50% bonus tax depreciation for capital investments placed in service through December 31, 2012.

Other long-term liabilities as of December 31, 2012 increased 3% compared with December 31, 2011. The increase was primarily due increase in the pension liability of $6,397,000 and the recording of a $9,756,000 contingent liability payable in 2013 through 2015 based on developments with the sugar provisions in the United States Farm Bill, associated with the purchase of Allied on November 1, 2012, partially offset by a $4,300,000 credit reducing the fair value of the contingent earnout liability associated with the acquisition of United in April 2011, and the reclassification of $9,202,000 of the long-term portion of the value of derivatives to short-term due to their February 28, 2013 maturity.

Total equity as of December 31, 2012 increased 17% compared with December 31, 2011. The increase was the result of $209,438,000 of net earnings attributable to Kirby for 2012, and a $4,951,000 decrease in accumulated OCI, a $7,415,000 decrease in treasury stock, and stock issued with a fair value of $29,080,000 in connection with the acquisition of Penn. The decrease in accumulated OCI primarily resulted from the increase in unrecognized losses related to the Company’s defined benefit plans. The decrease in treasury stock was attributable to the exercise of stock options and the issuance of restricted stock.

Retirement Plans

The Company sponsors a defined benefit plan for its inland vessel personnel and shore based tankermen. The plan benefits are based on an employee’s years of service and compensation. The plan assets consist primarily of equity and fixed income securities. The Company’s pension plan funding strategy has historically been to contribute an amount equal to the greater of the minimum required contribution under ERISA or the amount necessary to fully fund the plan on an accumulated benefit obligation (“ABO”) basis at the end of the fiscal year. No pension contribution was made in 2013 for the 2013 year as funding of the pension plan’s ABO was 127% at December 31, 2013.  The pension contribution for the 2012 year was $25,000,000 and resulted in funding 101% of the pension plan’s ABO at December 31, 2012. The fair value of plan assets was $254,523,000 and $217,811,000 at December 31, 2013 and December 31, 2012, respectively.
The Company’s investment strategy focuses on total return on invested assets (capital appreciation plus dividend and interest income). The primary objective in the investment management of assets is to achieve long-term growth of principal while avoiding excessive risk. Risk is managed through diversification of investments within and among asset classes, as well as by choosing securities that have an established trading and underlying operating history.

The Company makes various assumptions when determining defined benefit plan costs including, but not limited to, the current discount rate and the expected long-term return on plan assets. Discount rates are determined annually and are based on a yield curve that consists of a hypothetical portfolio of high quality corporate bonds with maturities matching the projected benefit cash flows. The Company used discount rates of 5.0% and 4.1% in 2013 and 2012, respectively, in determining its benefit obligations. The Company estimates that every 0.1% decrease in the discount rate results in an increase in the ABO of approximately $3,200,000. The Company assumed that plan assets would generate a long-term rate of return of 7.5% in 2013 and 2012. The Company developed its expected long-term rate of return assumption by evaluating input from investment consultants and comparing historical returns for various asset classes with its actual and targeted plan investments. The Company believes that long-term asset allocation, on average, will approximate the targeted allocation.

Long-Term Financing

The Company has $500,000,000 of unsecured senior notes (“Senior Notes Series A” and “Senior Notes Series B”) with a group of institutional investors, consisting of $150,000,000 of 2.72% Senior Notes Series A due February 27, 2020 and $350,000,000 of 3.29% Senior Notes Series B due February 27, 2023. The Company issued $82,500,000 of Senior Notes Series A and $192,500,000 of Senior Notes Series B on December 13, 2012, the proceeds of which were used to fund the acquisition of Penn. The Company issued $67,500,000 of Senior Notes Series A and $157,500,000 of Senior Notes Series B on February 27, 2013, the proceeds of which were used to refinance $200,000,000 of floating rate senior notes due February 28, 2013, with the balance used to pay down the Company’s unsecured revolving credit facility. No principal payments are required until maturity. The Senior Notes Series A and Series B contain certain covenants on the part of the Company, including an interest coverage covenant, a debt-to-capitalization covenant and covenants relating to liens, asset sales and mergers, among others. The Senior Notes Series A and Series B also specify certain events of default, upon the occurrence of which the maturity of the notes may be accelerated, including failure to pay principal and interest, violation of covenants or default on other indebtedness, among others. As of December 31, 2013, the Company was in compliance with all Senior Notes Series A and Series B covenants and had $150,000,000 of Senior Notes Series A outstanding and $350,000,000 of Senior Notes Series B outstanding.

The Company has a $325,000,000 unsecured revolving credit facility (“Revolving Credit Facility”) with a syndicate of banks, with JPMorgan Chase Bank, N.A. as the administrative agent bank, with a maturity date of November 9, 2015. The variable interest rate spread varies with the Company’s senior debt rating and is currently 1.5% over the London Interbank Offered Rate (“LIBOR”) or 0.5% over an alternate base rate calculated with reference to the agent bank’s prime rate, among other factors (“Alternate Base Rate”). The commitment fee is currently 0.3%. The Revolving Credit Facility contains certain restrictive financial covenants including an interest coverage ratio and a debt-to-capitalization ratio. In addition to financial covenants, the Revolving Credit Facility contains covenants that, subject to exceptions, restrict debt incurrence, mergers and acquisitions, sales of assets, dividends and investments, liquidations and dissolutions, capital leases, transactions with affiliates and changes in lines of business. Borrowings under the Revolving Credit Facility may be used for general corporate purposes, the purchase of existing or new equipment, the purchase of the Company’s common stock, or for business acquisitions. As of December 31, 2013, the Company was in compliance with all Revolving Credit Facility covenants and had $41,150,000 outstanding under the Revolving Credit Facility. The Revolving Credit Facility includes a $25,000,000 commitment which may be used for standby letters of credit. Outstanding letters of credit under the Revolving Credit Facility were $3,930,000 as of December 31, 2013.
The Company has a credit agreement (“Term Loan”) with a group of commercial banks, with Wells Fargo Bank, National Association as the administrative agent bank, with a maturity date of July 1, 2016. The Term Loan provides for a $540,000,000 five-year unsecured term loan facility with a variable interest rate based on LIBOR or an Alternate Base Rate. The interest rate spread varies with the Company’s senior debt rating and is currently 1.5% over LIBOR or 0.5% over the Alternate Base Rate. The outstanding balance of the Term Loan is subject to quarterly amortization in increasing amounts and is prepayable, in whole or in part, without penalty. The Term Loan contains certain restrictive financial covenants including an interest coverage ratio and a debt-to-capitalization ratio. In addition to financial covenants, the Term Loan contains covenants that, subject to exceptions, restrict debt incurrence, mergers and acquisitions, sales of assets, dividends and investments, liquidations and dissolutions, capital leases, transactions with affiliates and changes in lines of business. As of December 31, 2013, the Company was in compliance with all Term Loan covenants and had $208,000,000 outstanding under the Term Loan, none of which was classified as current portion of long-term debt. 

The Company had $200,000,000 of unsecured floating rate senior notes (“Senior Notes”) that were retired on February 28, 2013, the maturity date of the Senior Notes, with the proceeds from the Senior Notes Series A and Senior Notes Series B described above.

The Company has a $10,000,000 line of credit (“Credit Line”) with Bank of America for short-term liquidity needs and letters of credit, with a maturity date of June 29, 2014. The Credit Line allows the Company to borrow at an interest rate agreed to by Bank of America and the Company at the time each borrowing is made or continued. The Company had no borrowings outstanding under the Credit Line as of December 31, 2013. Outstanding letters of credit under the Credit Line were $869,000 as of December 31, 2013.

Interest Rate Risk Management

From time to time, the Company has utilized derivative financial instruments with respect to a portion of its interest rate risks to achieve a more predictable cash flow by reducing its exposure to interest rate fluctuations. These transactions generally are interest rate swap agreements and are entered into with large multinational banks. On February 28, 2013, all of the Company’s outstanding interest rate swaps expired. These interest rate swaps, with a notional amount of $200,000,000, were designated as cash flow hedges.

Foreign Currency Risk Management

From time to time, the Company has utilized derivative financial instruments with respect to its forecasted foreign currency transactions to attempt to reduce the risk of its exposure to foreign currency rate fluctuations in its transactions denominated in foreign currency. These transactions, which relate to foreign currency obligations for the purchase of equipment from foreign suppliers or foreign currency receipts from foreign customers, generally are forward contracts or purchased call options and are entered into with large multinational banks.

As of December 31, 2013, the Company had a forward contract with a notional amount of $469,000 to hedge its exposure to foreign currency rate fluctuations in expected foreign currency transactions. This contract expired in January 2014. This forward contract was designated as a cash flow hedge, therefore, the change in fair value, to the extent the forward contract was effective, was recognized in OCI until the forward contract expired and was recognized in cost of sales and operating expenses.

Fair value amounts were derived as of December 31, 2013 and December 31, 2012 utilizing fair value models of the Company and its counterparties on the Company’s portfolio of derivative instruments. These fair value models use the income approach that relies on inputs such as yield curves, currency exchange rates and forward prices. The fair value of the Company’s derivative instruments is described in Note 4, Fair Value Measurements.

Cash Flow Hedges

For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the derivative is reported as a component of OCI and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings. Any ineffectiveness related to the Company’s hedges was not material for any of the periods presented.

The following table sets forth the location and amount of gains and losses on the Company’s derivative instruments in the consolidated statements of earnings for the years ended December 31, 2013, 2012 and 2011 (in thousands):

The Company expects $59,000 of its net loss on a foreign currency contract included in accumulated OCI will be transferred into earnings over the next year based on the maturity date of the forward contract.

Capital Expenditures

Capital expenditures for 2013 were $253,227,000, including $147,786,000 for construction of new inland tank barges and towboats and progress payments on the construction of two offshore articulated dry-bulk barge and tugboat units completed in the 2013 second quarter, and $105,441,000 primarily for upgrading of the existing inland and coastal marine transportation equipment and diesel engine service facilities. Capital expenditures for 2012 were $312,167,000, including $135,622,000 for construction of inland tank barges and towboats, $60,373,000 for progress payments on the two offshore articulated dry-bulk barge and tugboat units, and $116,172,000 primarily for upgrading of the existing inland and coastal marine transportation equipment and diesel engine services facilities. Capital expenditures for 2011 were $226,238,000, including $114,703,000 for construction of inland tank barges and towboats, $33,335,000 for progress payments on the construction of the two offshore articulated dry-bulk barge and tugboat units, and $78,200,000 primarily for upgrading of the existing inland and coastal marine transportation equipment. Financing of the construction of the inland tank barges and towboats and offshore dry-bulk barges and tugboats was through operating cash flows and available credit under the Company’s Revolving Credit Facility.
During 2013, the Company took delivery of 70 new inland tank barges with a total capacity of approximately 1,400,000 barrels, retired 46 inland tank barges and returned four leased inland tank barges, reducing its capacity by approximately 800,000 barrels.  As a result, for 2013 the Company added a net 20 inland tank barges and approximately 600,000 barrels of capacity.  The Company’s inland operation also took delivery of three inland towboats during 2013.

The Company projects that capital expenditures for 2014 will be in the $200,000,000 to $210,000,000 range. The 2014 construction program will consist of 37 inland tank barges with a total capacity of approximately 390,000 barrels and progress payments on the construction of a 185,000 barrel coastal articulated tank barge and tugboat unit scheduled to be placed in service in mid-to-late 2015 at a cost of $75,000,000 to $80,000,000.  Based on current commitments, steel prices and projected delivery schedules, the Company’s 2014 payments on new inland tank barges will be approximately $45,000,000, and approximately $45,000,000 in  progress payments on the construction of the 185,000 barrel coastal articulated tank barge and tugboat unit. The balance of approximately $110,000,000 to $120,000,000 is primarily capital upgrades and improvements to existing marine equipment, and marine transportation and diesel engine services facilities.

Funding for future capital expenditures is expected to be provided through operating cash flows and available credit under the Company’s Revolving Credit Facility.

        Treasury Stock Purchases

The Company did not purchase any treasury stock during 2013, 2012 or 2011.  As of February 21, 2014, the Company had approximately 2,685,000 shares available under the existing repurchase authorization.  Historically, treasury stock purchases have been financed through operating cash flows and borrowings under the Company’s Revolving Credit Facility. The Company is authorized to purchase its common stock on the New York Stock Exchange and in privately negotiated transactions. When purchasing its common stock, the Company is subject to price, trading volume and other market considerations. Shares purchased may be used for reissuance upon the exercise of stock options or the granting of other forms of incentive compensation, in future acquisitions for stock or for other appropriate corporate purposes.

Liquidity

The Company generated net cash provided by operating activities of $601,032,000, $325,730,000 and $311,995,000 for the years ended December 31, 2013, 2012 and 2011, respectively. The 2013 year experienced a net increase in cash flows from changes in operating assets and liabilities of $56,566,000 compared with a net decrease in the 2012 year of $124,607,000.  The net increase was primarily due to a decrease in inventory during 2013 due to the sale during 2013 of inventories that were purchased in 2012 for specific customers and the sale of pressure pumping units on hand. In addition, deferred revenue increased during 2013 due to increased advance billings for coastal transportation customers compared to a decrease in deferred revenue during 2012. Also, there was no pension plan contribution in 2013 compared to a $25,000,000 pension plan contribution in 2012.

The 2012 year experienced a net decrease in cash flows from changes in operating assets and liabilities of $124,607,000 primarily due to a decrease in accounts payable during 2012 due to lower business activity levels at United and the timing of payments for inventory received at United which was acquired in April 2011.  In addition, deferred revenues had a larger decrease in 2012 versus 2011 reflecting reduced deposits received from customers for the construction of new oilfield service equipment in the land-based diesel engine services market.  The 2011 year experienced a net decrease in cash flows from changes in operating assets and liabilities of $79,618,000 primarily due to larger increases in trade accounts receivable and inventory from stronger business activity levels in 2011 versus 2010 and a pension contribution of $27,500,000 in December 2011.
Funds generated are available for acquisitions, capital expenditure projects, common stock repurchases, repayments of borrowings and for other corporate and operating requirements. In addition to net cash flow provided by operating activities, the Company also had available as of February 21, 2014, $287,654,000 under its Revolving Credit Facility and $8,221,000 available under its Credit Line.

Neither the Company, nor any of its subsidiaries, is obligated on any debt instrument, swap agreement, or any other financial instrument or commercial contract which has a rating trigger, except for pricing grids on its Revolving Credit Facility and Term Loan.

The Company expects to continue to fund expenditures for acquisitions, capital construction projects, common stock repurchases, repayment of borrowings, and for other operating requirements from a combination of available cash and cash equivalents, funds generated from operating activities and available financing arrangements.

The Revolving Credit Facility’s commitment is in the amount of $325,000,000 and expires November 9, 2015. As of December 31, 2013, the Company had $283,850,000 available under the Revolving Credit Facility. The Senior Notes Series A and Senior Notes Series B do not mature until February 27, 2020 and February 27, 2023, respectively, and require no prepayments. The outstanding balance of the Term Loan is subject to quarterly amortization in increasing amounts and is prepayable, in whole or in part, without penalty.

There are numerous factors that may negatively impact the Company’s cash flow in 2014. For a list of significant risks and uncertainties that could impact cash flows, see Note 14, Contingencies and Commitments in the financial statements, and Item 1A — Risk Factors. Amounts available under the Company’s existing financial arrangements are subject to the Company continuing to meet the covenants of the credit facilities as described in Note 6, Long-Term Debt in the financial statements.

The Company has issued guaranties or obtained standby letters of credit and performance bonds supporting performance by the Company and its subsidiaries of contractual or contingent legal obligations of the Company and its subsidiaries incurred in the ordinary course of business. The aggregate notional value of these instruments is $40,343,000 at December 31, 2013, including $6,108,000 in letters of credit and $34,235,000 in performance bonds. All of these instruments have an expiration date within four years. The Company does not believe demand for payment under these instruments is likely and expects no material cash outlays to occur in connection with these instruments.

All marine transportation term contracts contain fuel escalation clauses, or the customer pays for the fuel. However, there is generally a 30 to 90 day delay before contracts are adjusted depending on the specific contract. In general, the fuel escalation clauses are effective over the long-term in allowing the Company to recover changes in fuel costs due to fuel price changes. However, the short-term effectiveness of the fuel escalation clauses can be affected by a number of factors including, but not limited to, specific terms of the fuel escalation formulas, fuel price volatility, navigating conditions, tow sizes, trip routing, and the location of loading and discharge ports that may result in the Company over or under recovering its fuel costs. Spot contract rates generally reflect current fuel prices at the time the contract is signed but do not have escalators for fuel.

During the last three years, inflation has had a relatively minor effect on the financial results of the Company. The marine transportation segment has long-term contracts which generally contain cost escalation clauses whereby certain costs, including fuel as noted above, can be passed through to its customers. Spot contract rates include the cost of fuel and are subject to market volatility. The repair portion of the diesel engine services segment is based on prevailing current market rates.

Approximately half of the towboat charter agreements are for terms of one year or less. The Company’s towboat rental agreements provide the Company with the option to terminate most agreements with notice ranging from seven to 90 days. The Company estimates that 80% of the charter rental cost is related to towboat crew costs, maintenance and insurance.

The Company’s pension plan funding strategy has historically been to contribute an amount equal to the greater of the minimum required contribution under ERISA or the amount necessary to fully fund the plan on an ABO basis at the end of the fiscal year. The ABO is based on a variety of demographic and economic assumptions, and the pension plan assets’ returns are subject to various risks, including market and interest rate risk, making an accurate prediction of the pension plan contribution difficult resulting in the Company electing to only make an expected pension contribution forecast of one year. As of December 31, 2013, the pension plan was funded at 127% of the ABO.

Accounting Standard

In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2013-02, “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” (“ASU 2013-02”). ASU 2013-02 established the effective date for the requirement to present components of reclassifications out of accumulated OCI on the face of the financial statements. The adoption of ASU 2013-02 in the first quarter of 2013 did not have an impact on the Company’s consolidated financial statements except the Company has applied these provisions to its presentation of consolidated financial statements.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

The Company is exposed to risk from changes in interest rates on certain of its outstanding debt. The outstanding loan balances under the Company’s bank credit facilities bear interest at variable rates based on prevailing short-term interest rates in the United States and Europe. A 10% change in variable interest rates would impact the 2014 interest expense by $64,000 based on balances outstanding at December 31, 2013, and would change the fair value of the Company’s debt by approximately 1.3%.

Interest Rate Risk Management

From time to time, the Company has utilized derivative financial instruments with respect to a portion of its interest rate risks to achieve a more predictable cash flow by reducing its exposure to interest rate fluctuations. These transactions generally are interest rate swap agreements and are entered into with large multinational banks. On February 28, 2013, all of the Company’s outstanding interest rate swaps expired. These interest rate swaps, with a total notional amount of $200,000,000, were designated as cash flow hedges.
Foreign Currency Risk Management

From time to time, the Company has utilized derivative financial instruments with respect to its forecasted foreign currency transactions to attempt to reduce the risk of its exposure to foreign currency rate fluctuations in its transactions denominated in foreign currency. These transactions, which relate to foreign currency obligations for the purchase of equipment from foreign suppliers or foreign currency receipts from foreign customers, generally are forward contracts or purchased call options and are entered into with large multinational banks.

As of December 31, 2013, the Company had a forward contract with a notional amount of $469,000 to hedge its exposure to foreign currency rate fluctuations in expected foreign currency transactions. This contract expired in January 2014. This forward contract was designated as a cash flow hedge, therefore, the change in fair value, to the extent the forward contract was effective, was recognized in OCI until the forward contract expired and was recognized in cost of sales and operating expenses.

Fair value amounts were derived as of December 31, 2013 and December 31, 2012 utilizing fair value models of the Company and its counterparties on the Company’s portfolio of derivative instruments. These fair value models use the income approach that relies on inputs such as yield curves, currency exchange rates and forward prices. The fair value of the Company’s derivative instruments is described in Note 4, Fair Value Measurements.
Cash Flow Hedges

For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the derivative is reported as a component of OCI and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings. Any ineffectiveness related to the Company’s hedges was not material for any of the periods presented.

The response to this item is submitted as a separate section of this report (see Item 15, page 99).

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

Not applicable.
Item 9A.                          Controls and Procedures

Disclosure Controls and Procedures. The Company’s management, with the participation of the Chief Executive Officer and the Chief Financial Officer, has evaluated the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)), as of December 31, 2013. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that, as of December 31, 2013, the disclosure controls and procedures were effective to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms.

Management’s Report on Internal Control Over Financial Reporting. Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act). The Company’s management, with the participation of the Chief Executive Officer and the Chief Financial Officer, evaluated the effectiveness of the Company’s internal control over financial reporting as of December 31, 2013 using the framework in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on that evaluation, management concluded that the Company’s internal control over financial reporting was effective as of December 31, 2013. KPMG LLP, the Company’s independent registered public accounting firm, has audited the Company’s internal control over financial reporting, as stated in their report which is included herein.

There were no changes in the Company’s internal control over financial reporting during the quarter ended December 31, 2013 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART III

Items 10 Through 14.

The information for these items is incorporated by reference to the definitive proxy statement filed by the Company with the Commission pursuant to Regulation 14A within 120 days of the close of the fiscal year ended December 31, 2013, except for the information regarding executive officers which is provided under Item 1.
Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of Kirby Corporation:

We have audited Kirby Corporation and consolidated subsidiaries’ internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Kirby Corporation’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, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included 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, Kirby Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Kirby Corporation and consolidated subsidiaries as of December 31, 2013 and 2012, and the related consolidated statements of earnings, stockholders’ equity and comprehensive income, and cash flows for each of the years in the three-year period ended December 31, 2013, and our report dated February 24, 2014 expressed an unqualified opinion on those consolidated financial statements.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of Kirby Corporation:

We have audited the accompanying consolidated balance sheets of Kirby Corporation and consolidated subsidiaries as of December 31, 2013 and 2012, and the related consolidated statements of earnings, stockholders’ equity and comprehensive income, and cash flows for each of the years in the three-year period ended December 31, 2013. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements 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 financial position of Kirby Corporation and consolidated subsidiaries as of December 31, 2013 and 2012, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2013, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Kirby Corporation’s internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated February 24, 2014 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) Summary of Significant Accounting Policies

Principles of Consolidation. The consolidated financial statements include the accounts of Kirby Corporation and all majority-owned subsidiaries (“the Company”). Two affiliated limited partnerships, in which the Company owns a 50% interest, is the general partner and has effective control and whose activities are an integral part of the operations of the Company, are consolidated. All other investments in which the Company owns 20% to 50% and exercises significant influence over operating and financial policies are accounted for using the equity method. All material intercompany accounts and transactions have been eliminated in consolidation. Certain reclassifications have been made to reflect the current presentation of financial information.

Accounting Policies

Cash Equivalents. Cash equivalents consist of all short-term, highly liquid investments with maturities of three months or less at date of purchase.

Accounts Receivable. In the normal course of business, the Company extends credit to its customers. The Company regularly reviews the accounts and makes adequate provisions for probable uncollectible balances. It is the Company’s opinion that the accounts have no impairment, other than that for which provisions have been made. Included in accounts receivable as of December 31, 2013 and 2012 were $69,481,000 and $81,447,000, respectively, of accruals for revenues earned which have not been invoiced as of the end of each year.

The Company’s marine transportation and diesel engine services operations are subject to hazards associated with such businesses. The Company maintains insurance coverage against these hazards with insurance companies. Included in accounts receivable as of December 31, 2013 and 2012 were $22,396,000 and $20,953,000, respectively, of receivables from insurance companies to cover claims in excess of the Company’s deductible.

Concentrations of Credit Risk. Financial instruments which potentially subject the Company to concentrations of credit risk are primarily trade accounts receivables. The Company’s marine transportation customers include the major oil refining and petrochemical companies. The diesel engine services customers are oil and gas service companies, marine transportation companies, commercial fishing companies, power generation companies, and the United States government. The Company regularly reviews its accounts and estimates the amount of uncollectible receivables each period and establishes an allowance for uncollectible amounts. The amount of the allowance is based on the age of unpaid amounts, information about the current financial strength of customers, and other relevant information. Estimates of uncollectible amounts are revised each period, and changes are recorded in the period they become known.

Fair Value of Financial Instruments. Cash, accounts receivable, accounts payable and accrued liabilities have carrying values that approximate fair value due to the short-term maturity of these financial instruments. The fair value of the Company’s debt instruments is more fully described in Note 6, Long-Term Debt.

Property, Maintenance and Repairs. Property is recorded at cost. Improvements and betterments are capitalized as incurred. Depreciation is recorded on the straight-line method over the estimated useful lives of the individual assets as follows: marine transportation equipment, 5-40 years; buildings, 10-40 years; other equipment, 2-10 years; and leasehold improvements, term of lease. When property items are retired, sold or otherwise disposed of, the related cost and accumulated depreciation are removed from the accounts with any gain or loss on the disposition included in the statement of earnings. Maintenance and repairs on vessels built for use on the inland waterways are charged to operating expense as incurred and includes the costs incurred in United States Coast Guard (“USCG”) inspections unless the shipyard extends the life or improves the operating capacity of the vessel which results in the costs being capitalized.

Drydocking on Ocean-Going Vessels. The Company’s ocean-going vessels are subject to regulatory drydocking requirements after certain periods of time to be inspected, have planned major maintenance performed and be recertified by the American Bureau of Shipping (“ABS”). These recertifications generally occur twice in a five year period. The Company defers the drydocking expenditures incurred on its ocean-going vessels due to regulatory marine inspections by the ABS and amortizes the costs of the shipyard over the period between drydockings, generally 30 or 60 months, depending on the type of major maintenance performed. Drydocking expenditures that extend the life or improve the operating capability of the vessel result in the costs being capitalized. Routine repairs and maintenance on ocean-going vessels are expensed as incurred.
Environmental Liabilities. The Company expenses costs related to environmental events as they are incurred or when a loss is considered probable and estimable.

Goodwill. The excess of the purchase price over the fair value of identifiable net assets acquired in transactions accounted for as a purchase is included in goodwill. The Company conducted its annual goodwill impairment test at November 30, 2013 and 2012. For 2013 and 2012, the Company noted no impairment of goodwill. The Company will continue to conduct goodwill impairment tests as of November 30 of subsequent years, or whenever events or circumstances indicate that interim impairment testing is necessary. The gross carrying value of goodwill at December 31, 2013 and 2012 was $608,872,000 and $613,497,000, respectively and accumulated amortization at December 31, 2013 and 2012 was $15,566,000. Accumulated impairment losses were $1,901,000 at December 31, 2013 and 2012.

Net goodwill for the marine transportation segment was $381,243,000 and $385,868,000 at December 31, 2013 and 2012, respectively. Net goodwill for the diesel engine services segment was $210,162,000 at December 31, 2013 and 2012.

Revenue Recognition. The majority of marine transportation revenue is derived from term contracts, ranging from one to five years, some of which have renewal options, and the remainder is from spot market movements. The majority of the term contracts are for terms of one year. The Company is a provider of marine transportation services for its customers and, in almost all cases, does not assume ownership of the products it transports. A term contract is an agreement with a specific customer to transport cargo from a designated origin to a designated destination at a set rate or at a daily rate. The rate may or may not escalate during the term of the contract, however, the base rate generally remains constant and contracts often include escalation provisions to recover changes in specific costs such as fuel. A spot contract is an agreement with a customer to move cargo from a specific origin to a designated destination for a rate negotiated at the time the cargo movement takes place. Spot contract rates are at the current “market” rate, including fuel, and are subject to market volatility. The Company uses a voyage accounting method of revenue recognition for its marine transportation revenues which allocates voyage revenue based on the percent of the voyage completed during the period. There is no difference in the recognition of revenue between a term contract and a spot contract.

Diesel engine service products and services are generally sold based upon purchase orders or preferential service agreements with the customer that include fixed or determinable prices and that do not include right of return or significant post-delivery performance obligations. Diesel engine parts sales are recognized when title passes upon shipment to customers or when customer-specific acceptance requirements are met. Service revenue is recognized as the service is provided. Diesel manufacturing and assembly projects revenue is reported on the percentage of completion method of accounting using measurements of progress towards completion appropriate for the work performed.

Stock-Based Compensation. The Company has share-based compensation plans covering selected officers and other key employees as well as the Company’s Board of Directors. Stock-based grants made under the Company’s stock plans are recorded at fair value on the date of the grant and the cost is recognized ratably over the vesting period of the stock option or restricted stock. Stock option grants are valued at the date of grant as calculated under the Black-Scholes option pricing model. The Company’s stock-based compensation plans are more fully described in Note 9, Stock Award Plans.

Taxes on Income. The Company follows the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
Accrued Insurance. Accrued insurance liabilities include estimates based on individual incurred claims outstanding and an estimated amount for losses incurred but not reported (“IBNR”) or fully developed based on past experience. Insurance premiums, IBNR losses and incurred claim losses, in excess of the Company’s deductible for 2013, 2012 and 2011 were $22,971,000, $17,876,000 and $18,673,000, respectively.

Noncontrolling Interests. The Company has a majority interest in and is the general partner in several affiliated entities. In situations where losses applicable to the minority interest in the affiliated entities exceed the limited partners’ equity capital, such excess and any further loss attributable to the minority interest is charged against the Company’s interest in the affiliated entities. If future earnings materialize in the respective affiliated entities, the Company’s interest would be credited to the extent of any losses previously absorbed.

Treasury Stock. The Company follows the average cost method of accounting for treasury stock transactions.

Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of. The Company reviews long-lived assets and certain identifiable intangibles for impairment by vessel class whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable.

Recoverability on marine transportation assets is assessed based on vessel classes, not on individual assets, because identifiable cash flows for individual marine transportation assets are not available. Projecting customer contract volumes allows estimation of future cash flows by projecting pricing and utilization by vessel class but it is not practical to project which individual marine transportation asset will be utilized for any given contract. Because customers do not specify which particular vessel is used, prices are quoted based on vessel classes not individual assets. Nominations of vessels for specific jobs are determined on a day by day basis and are a function of the equipment class required and the geographic position of vessels within that class at that particular time as vessels within a class are interchangeable and provide the same service. The Company’s vessels are mobile assets and equipped to operate in geographic regions throughout the United States and the Company has in the past and expects to continue to move vessels from one region to another when it is necessary due to changing markets and it is economical to do so. Barge vessel classes are based on similar capacities, hull type, and type of product and towing vessels are based on similar hull type and horsepower. Recoverability of the vessel classes is measured by a comparison of the carrying amount of the assets to future net cash flows expected to be generated by the assets. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.

Accounting Standard

In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2013-02, “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” (“ASU 2013-02”). ASU 2013-02 established the effective date for the requirement to present components of reclassifications out of accumulated other comprehensive income (“OCI”) on the face of the financial statements. The adoption of ASU 2013-02 in the first quarter of 2013 did not have an impact on the Company’s consolidated financial statements except the Company has applied these provisions to its presentation of consolidated financial statements.

(2) Acquisitions

On December 28, 2012, the Company purchased the assets of Flag Service & Maintenance, Inc. (“Flag”) for $6,864,000 in cash.

The fair value of the contingent liability recorded at the acquisition date was $9,756,000. A payment of $5,000,000 was made in the 2013 first quarter on the contingent liability. Allied provided coastal transportation of petrochemicals as well as dry sugar products in the Northeast, Atlantic and Gulf Coast regions of the United States.

On December 15, 2011, the Company completed the purchase of the coastal tank barge fleet of Seaboats, Inc. and affiliated companies (“Seaboats”) consisting of three 80,000 barrel coastal tank barges and tugboats for $42,745,000 in cash. The three coastal tank barges and tugboats currently operate along the United States East Coast and had an average age of five years.

On July 1, 2011, the Company completed the acquisition of K-Sea Transportation Partners L.P. (“K-Sea”), an operator of tank barges and tugboats participating in the coastal transportation primarily of refined petroleum products in the United States. The total value of the transaction was $603,427,000, excluding transaction fees, consisting of $227,617,000 of cash paid to K-Sea common and preferred unit holders and the general partner, $262,791,000 of cash to retire K-Sea’s outstanding debt, and $113,019,000 through the issuance of 1,939,234 shares of Company common stock valued at $58.28 per share, the Company’s closing share price on July 1, 2011.

On April 17, 2012, the Company changed the name of K-Sea to Kirby Offshore Marine, LLC (“Kirby Offshore Marine”) to more fully integrate the Company’s coastal operations with the Company’s inland marine transportation operations. The acquired company is referred to in this report as either K-Sea or Kirby Offshore Marine, depending on the context.

On the acquisition date, Kirby Offshore Marine’s fleet, comprised of 57 coastal tank barges with a capacity of 3.8 million barrels and 63 tugboats, operated along the East Coast, West Coast and Gulf Coast of the United States, as well as in Alaska and Hawaii. Kirby Offshore Marine’s tank barge fleet, 54 of which were double hulled and had an average age of approximately nine years, is one of the youngest fleets in the coastal trade. Kirby Offshore Marine’s customers include major oil companies and refiners, many of which are current Company customers for inland tank barge services. Kirby Offshore Marine has operating facilities in New York, Seattle and Honolulu.

On April 15, 2011, the Company purchased United Holdings LLC (“United”), a distributor and service provider of engine and transmission related products for the oil and gas services, power generation and on-highway transportation industries, and manufacturer of oilfield service equipment. The purchase price was $271,192,000 in cash, plus a three-year earnout provision for up to an additional $50,000,000 payable in 2014, dependent on achieving certain financial targets. As of December 31, 2013, the financial targets were not achieved and no payment will be made.  United, headquartered in Oklahoma City, Oklahoma with 21 locations across seven states, distributes and services equipment and parts for Allison Transmission (“Allison”), MTU, Daimler Trucks NA (“Daimler”), and other diesel and natural gas engines. United also manufactures oilfield service equipment, including pressure pumping units. United’s principal customers are oilfield service companies, oil and gas operators and producers, compression companies and on-highway transportation companies.

On February 24, 2011, the Company purchased 21 inland and offshore tank barges and 15 inland towboats and offshore tugboats from Enterprise Marine Services LLC (“Enterprise”) for $53,200,000 in cash. Enterprise provided transportation and delivery services for ship bunkers (engine fuel) to cruise ships, container ships and freighters primarily in the Miami, Port Everglades and Cape Canaveral, Florida area, the three largest cruise ship ports in the United States, as well as Tampa, Florida, Mobile, Alabama and Houston, Texas.
On February 9, 2011, the Company purchased from Kinder Morgan Petcoke, L.P. (“Kinder Morgan”) for $4,050,000 in cash a 51% interest in Kinder Morgan’s shifting operation and fleeting facility for dry cargo barges and tank barges on the Houston Ship Channel. Kinder Morgan retained the remaining 49% interest and the Company will manage the operation. In addition, the Company purchased a towboat from Kinder Morgan for $1,250,000 in cash.

The following unaudited pro forma results present consolidated information as if the United and K-Sea acquisitions had been completed as of January 1, 2011. The pro forma results do not include the acquisitions of Flag, Penn, Allied, Seaboats, Enterprise and Kinder Morgan described above as the effect of these acquisitions would not be materially different from the Company’s actual results.

The pro forma results include the amortization associated with the acquired intangible assets, interest expense associated with the debt used to fund a portion of the acquisitions, the impact of the additional shares issued in connection with the K-Sea acquisition, the impact of certain fair value adjustments such as depreciation adjustments related to adjustments to property and equipment and standardization of accounting policies. The pro forma results do not include any cost savings or potential synergies related to the acquisitions nor any integration costs. The pro forma results should not be considered indicative of the results of operations or financial position of the combined companies had the acquisitions been consummated as of January 1, 2011, and are not necessarily indicative of results of future operations of the Company.

The following table sets forth the Company’s pro forma revenues, net earnings attributable to Kirby, basic net earnings per share and fully diluted net earnings per share attributable to Kirby common stockholders for the years ended December 31, 2013, 2012 and 2011 (in thousands, except per share amounts):

(4) Fair Value Measurements

The accounting guidance for using fair value to measure certain assets and liabilities establishes a three tier value hierarchy, which prioritizes the inputs to valuation techniques used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little, if any, market data exists, therefore requiring an entity to develop its own assumptions about the assumptions that market participants would use in pricing the asset or liability.

The following table summarizes the assets and liabilities measured at fair value on a recurring basis at December 31, 2013 and 2012 (in thousands):

In connection with the acquisition of Allied on November 1, 2012, Allied’s former owners are eligible to receive up to an additional $10,000,000 payable in 2013 through 2015, contingent on developments with the sugar provisions in the United States Farm Bill. The fair value of the contingent liability recorded at the acquisition date was $9,756,000. The fair value of the contingent liability is based on a valuation of the estimated fair value of the liability after probability weighting and discounting various potential payments. A payment of $5,000,000 was made in the 2013 first quarter on the contingent liability. The increase in the fair value of the contingent liability of $136,000 and $11,000 for the years ended December 31, 2013 and 2012, respectively, was charged to selling, general and administrative expense. As of December 31, 2013, the Company had recorded a contingent liability of $4,903,000.

In connection with the acquisition of United on April 15, 2011, United’s former owners were eligible to receive a three-year earnout provision for up to an additional $50,000,000 payable in 2014, dependent on achieving certain financial targets. The fair value of the contingent earnout liability recorded at the acquisition date was $16,300,000. The fair value of the earnout was based on a valuation of the estimated fair value of the liability after probability weighting and discounting various potential payments. The decrease in the fair value of the earnout liability of $18,300,000 and $4,300,000 for the years ended December 31, 2013 and 2012, respectively, were credited to selling, general and administrative expense. As of December 31, 2013, the financial targets were not achieved and no payment will be made.  No United earnout liability was recorded as of December 31, 2013 compared with $18,300,000 as of December 31, 2012.
Cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities have carrying values that approximate fair value due to the short-term maturity of these financial instruments.  The fair value of the Company’s debt instruments is described in Note 6, Long-Term Debt.

Certain assets are measured at fair value on a nonrecurring basis and therefore are not included in the table above. These assets are adjusted to fair value when there is evidence of impairment. During the years ended December 31, 2013 and 2012, there was no indication that the Company’s long-lived assets were impaired, and accordingly, measurement at fair value was not required.

(5) Derivative Instruments

The Company recognizes all derivative instruments at fair value in the balance sheet as either assets or liabilities. The accounting for changes in the fair value of a derivative instrument depends on the intended use of the derivative and the resulting designation, which is established at the inception date of a derivative. For derivative instruments designated as cash flow hedges, changes in fair value, to the extent the hedge is effective, are recognized in OCI until the hedged item is recognized in earnings. Hedge effectiveness is measured at least quarterly based on the cumulative difference between the fair value of the derivative contract and the hedged item over time. Any change in fair value resulting from ineffectiveness is recognized immediately in earnings.

Interest Rate Risk Management

From time to time, the Company has utilized derivative financial instruments with respect to a portion of its interest rate risks to achieve a more predictable cash flow by reducing its exposure to interest rate fluctuations. These transactions generally are interest rate swap agreements and are entered into with large multinational banks. On February 28, 2013, all of the Company’s outstanding interest rate swaps expired. These interest rate swaps, with a total notional amount of $200,000,000, were designated as cash flow hedges.

Foreign Currency Risk Management

From time to time, the Company has utilized derivative financial instruments with respect to its forecasted foreign currency transactions to attempt to reduce the risk of its exposure to foreign currency rate fluctuations in its transactions denominated in foreign currency. These transactions, which relate to foreign currency obligations for the purchase of equipment from foreign suppliers or foreign currency receipts from foreign customers, generally are forward contracts or purchased call options and are entered into with large multinational banks.

As of December 31, 2013, the Company had a forward contract with a notional amount of $469,000 to hedge its exposure to foreign currency rate fluctuations in expected foreign currency transactions. This contract expired in January 2014. This forward contract was designated as a cash flow hedge, therefore, the change in fair value, to the extent the forward contract was effective, was recognized in OCI until the forward contract expired and was recognized in cost of sales and operating expenses.

Fair Value of Derivative Instruments

Fair value amounts were derived as of December 31, 2013 and 2012 utilizing fair value models of the Company and its counterparties on the Company’s portfolio of derivative instruments. These fair value models use the income approach that relies on inputs such as yield curves, currency exchange rates and forward prices. The fair value of the Company’s derivative instruments is described above in Note 4, Fair Value Measurements.

Cash Flow Hedges

For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the derivative is reported as a component of OCI and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings. Any ineffectiveness related to the Company’s hedges was not material for any of the periods presented.

The following table sets forth the location and amount of gains and losses on the Company’s derivative instruments in the consolidated statements of earnings for the years ended December 31, 2013, 2012 and 2011 (in thousands):

The Company has $500,000,000 of unsecured senior notes (“Senior Notes Series A” and “Senior Notes Series B”) with a group of institutional investors, consisting of $150,000,000 of 2.72% Senior Notes Series A due February 27, 2020 and $350,000,000 of 3.29% Senior Notes Series B due February 27, 2023. The Company issued $82,500,000 of Senior Notes Series A and $192,500,000 of Senior Notes Series B on December 13, 2012, the proceeds of which were used to fund the acquisition of Penn. The Company issued $67,500,000 of Senior Notes Series A and $157,500,000 of Senior Notes Series B on February 27, 2013, the proceeds of which were used to refinance $200,000,000 of floating rate senior notes due February 28, 2013, with the balance used to pay down the Company’s unsecured revolving credit facility. No principal payments are required until maturity. The Senior Notes Series A and Series B contain certain covenants on the part of the Company, including an interest coverage covenant, a debt-to-capitalization covenant and covenants relating to liens, asset sales and mergers, among others. The Senior Notes Series A and Series B also specify certain events of default, upon the occurrence of which the maturity of the notes may be accelerated, including failure to pay principal and interest, violation of covenants or default on other indebtedness, among others. As of December 31, 2013, the Company was in compliance with all Senior Notes Series A and Series B covenants and had $150,000,000 of Senior Notes Series A outstanding and $350,000,000 of Senior Notes Series B outstanding.
The Company has a $325,000,000 unsecured revolving credit facility (“Revolving Credit Facility”) with a syndicate of banks, with JPMorgan Chase Bank, N.A. as the administrative agent bank, with a maturity date of November 9, 2015. The variable interest rate spread varies with the Company’s senior debt rating and is currently 1.5% over LIBOR or 0.5% over an alternate base rate calculated with reference to the agent bank’s prime rate, among other factors (“Alternate Base Rate”). The commitment fee is currently 0.3%. The Revolving Credit Facility contains certain restrictive financial covenants including an interest coverage ratio and a debt-to-capitalization ratio. In addition to financial covenants, the Revolving Credit Facility contains covenants that, subject to exceptions, restrict debt incurrence, mergers and acquisitions, sales of assets, dividends and investments, liquidations and dissolutions, capital leases, transactions with affiliates and changes in lines of business. Borrowings under the Revolving Credit Facility may be used for general corporate purposes, the purchase of existing or new equipment, the purchase of the Company’s common stock, or for business acquisitions. As of December 31, 2013, the Company was in compliance with all Revolving Credit Facility covenants and had $41,150,000 outstanding under the Revolving Credit Facility. The average borrowing under the Revolving Credit Facility during 2013 was $75,113,000, computing by averaging the daily balance, and the weighted average interest rate was 1.7%, computed by dividing the interest expense under the Revolving Credit Facility by the average Revolving Credit Facility borrowing. The Revolving Credit Facility includes a $25,000,000 commitment which may be used for standby letters of credit. Outstanding letters of credit under the Revolving Credit Facility were $3,930,000 as of December 31, 2013.

The Company has a credit agreement (“Term Loan”) with a group of commercial banks, with Wells Fargo Bank, National Association as the administrative agent bank, with a maturity date of July 1, 2016. The Term Loan provides for a $540,000,000 five-year unsecured term loan facility with a variable interest rate based on LIBOR or an Alternate Base Rate.

The outstanding balance of the Term Loan is subject to quarterly amortization in increasing amounts and is prepayable, in whole or in part, without penalty. The Term Loan contains certain restrictive financial covenants including an interest coverage ratio and a debt-to-capitalization ratio. In addition to financial covenants, the Term Loan contains covenants that, subject to exceptions, restrict debt incurrence, mergers and acquisitions, sales of assets, dividends and investments, liquidations and dissolutions, capital leases, transactions with affiliates and changes in lines of business. As of December 31, 2013, the Company was in compliance with all Term Loan covenants and had $208,000,000 outstanding under the Term Loan, none of which was classified as current portion of long-term debt. The average borrowing under the Term Loan during 2013 was $401,270,000, computed by averaging the daily balance, and the weighted average interest rate was 1.7%, computed by dividing the interest expense under the Term Loan by the average Term Loan borrowing.

The Company had $200,000,000 of unsecured floating rate senior notes (“Senior Notes”) that were retired on February 28, 2013, the maturity date of the Senior Notes, with the proceeds from the Senior Notes Series A and Senior Notes Series B described above.
The Company has a $10,000,000 line of credit (“Credit Line”) with Bank of America, N.A. (“Bank of America”) for short-term liquidity needs and letters of credit, with a maturity date of June 29, 2014. The Credit Line allows the Company to borrow at an interest rate agreed to by Bank of America and the Company at the time each borrowing is made or continued. The Company had no borrowings outstanding under the Credit Line as of December 31, 2013. Outstanding letters of credit under the Credit Line were $869,000 as of December 31, 2013.

The estimated fair value of total debt outstanding at December 31, 2013 and 2012 was $710,377,000 and $1,130,967,000, respectively, which differs from the carrying amount of $749,150,000 and $1,135,110,000, respectively, included in the consolidated financial statements. The fair value was determined using an income approach that relies on inputs such as yield curves.

The Company has determined that it is more likely than not that all deferred tax assets at December 31, 2013 will be realized, including its operating loss carryforwards of $5,699,000 that expire in various amounts through 2030.

The Company or one of its subsidiaries files income tax returns in the United States federal jurisdiction and various state jurisdictions. The Company is currently open to audit under the statute of limitations by the Internal Revenue Service for the 2010 through 2012 tax years. With few exceptions, the Company and its subsidiaries’ state income tax returns are open to audit under the statute of limitations for the 2007 through 2012 tax years.

As of December 31, 2013, the Company has provided a liability of $1,215,000 for unrecognized tax benefits related to various income tax issues which includes interest and penalties. The amount that would impact the Company’s effective tax rate, if recognized, is $827,000, with the difference between the total amount of unrecognized tax benefits and the amount that would impact the effective tax rate being primarily related to the federal tax benefit of state income tax items. It is not reasonably possible to determine if the liability for unrecognized tax benefits will significantly change prior to December 31, 2014 due to the uncertainty of possible examination results.
A reconciliation of the beginning and ending amount of the liability for unrecognized tax benefits for the years ended December 31, 2013, 2012 and 2011, is as follows (in thousands):

The Company has a director stock award plan for nonemployee directors of the Company which provides for the issuance of stock options and restricted stock. The director plan provides for the automatic grants of stock options and restricted stock to nonemployee directors on the date of first election as a director and after each annual meeting of stockholders.

The exercise prices for all options granted under the plan are equal to the fair market value per share of the Company’s common stock on the date of grant. The terms of the options are ten years. The options granted to a director when first elected vest immediately. The options granted and restricted stock issued after each annual meeting of stockholders vest six months after the date of grant.

The total intrinsic value of all the restricted stock vestings under all of the Company’s plans was $10,993,000, $11,878,000 and $7,921,000 for the years ended December 31, 2013, 2012 and 2011, respectively. The actual tax benefit realized for tax deductions from restricted stock vestings was $4,133,000, $4,418,000 and $3,034,000 for the years ended December 31, 2013, 2012 and 2011, respectively.

As of December 31, 2013, there was $2,576,000 of unrecognized compensation cost related to nonvested stock options and $15,854,000 related to restricted stock. The stock options are expected to be recognized over a weighted average period of approximately 1.2 years and restricted stock over approximately 2.6 years. The total fair value of stock options vested was $3,341,000, $2,846,000 and $2,618,000 during the years ended December 31, 2013, 2012 and 2011, respectively. The fair value of the restricted stock vested was $10,993,000, $11,878,000 and $7,921,000 for the years ended December 31, 2013, 2012 and 2011, respectively.

The weighted average per share fair value of stock options granted during the years ended December 31, 2013, 2012 and 2011 was $25.14, $22.21 and $18.84, respectively. The fair value of the stock options granted during the years ended December 31, 2013, 2012 and 2011 was $4,184,000, $3,691,000 and $3,081,000, respectively. The Company currently uses treasury stock shares for restricted stock grants and stock option exercises. The fair value of each stock option was determined using the Black-Scholes option pricing model. The key input variables used in valuing the stock options during the years ended December 31, 2013, 2012 and 2011 were as follows:

(10) Retirement Plans

The Company sponsors a defined benefit plan for its inland vessel personnel and shore based tankermen. The plan benefits are based on an employee’s years of service and compensation. The plan assets consist primarily of equity and fixed income securities.

The fair value of plan assets was $254,523,000 and $217,811,000 at December 31, 2013 and 2012 respectively. As of December 31, 2013 and 2012, these assets were allocated among asset categories as follows:

The cash and cash equivalents asset category exceeded the maximum percentage allocation in 2012 due to the 2012 pension plan contribution of $25,000,000 being funded on the last day of the year which resulted in insufficient time to properly allocate the contribution among the asset categories. The Company allocated the contribution among the appropriate asset categories in January 2013.

The plan assets are invested entirely in common collective trusts. These instruments are public investment vehicles valued using the net asset value provided by the administrator of the fund. The net asset value is classified within Level 2 of the valuation hierarchy as set forth in the accounting guidance for fair value measurements because the net asset value price is quoted on an inactive private market although the underlying investments are traded on an active market.

The Company’s investment strategy focuses on total return on invested assets (capital appreciation plus dividend and interest income). The primary objective in the investment management of assets is to achieve long-term growth of principal while avoiding excessive risk. Risk is managed through diversification of investments within and among asset classes, as well as by choosing securities that have an established trading and underlying operating history.

The Company makes various assumptions when determining defined benefit plan costs including, but not limited to, the current discount rate and the expected long-term return on plan assets. Discount rates are determined annually and are based on a yield curve that consists of a hypothetical portfolio of high quality corporate bonds with maturities matching the projected benefit cash flows. The Company assumed that plan assets would generate a long-term rate of return of 7.5% in 2013 and 2012. The Company developed its expected long-term rate of return assumption by evaluating input from investment consultants comparing historical returns for various asset classes with its actual and targeted plan investments. The Company believes that its long-term asset allocation, on average, will approximate the targeted allocation.

The Company’s pension plan funding strategy has historically been to contribute an amount equal to the greater of the minimum required contribution under ERISA or the amount necessary to fully fund the plan on an accumulated benefit obligation (“ABO”) basis at the end of the fiscal year. The ABO is based on a variety of demographic and economic assumptions, and the pension plan assets’ returns are subject to various risks, including market and interest rate risk, making an accurate prediction of the pension plan contribution difficult. The Company’s pension plan funding was 127% of the pension plan’s ABO at December 31, 2013.
The Company sponsors an unfunded defined benefit health care plan that provides limited postretirement medical benefits to employees who met minimum age and service requirements, and to eligible dependents. The plan limits cost increases in the Company’s contribution to 4% per year. The plan is contributory, with retiree contributions adjusted annually. The plan eliminated coverage for future retirees as of December 31, 2011. The Company also has an unfunded defined benefit supplemental executive retirement plan (“SERP”) that was assumed in an acquisition in 1999. That plan ceased to accrue additional benefits effective January 1, 2000.

The Company also contributes to a multiemployer pension plan pursuant to a collective bargaining agreement which covers certain vessel crew members of its coastal operations and expires on April 30, 2015. The Company began participation in the Seafarers Pension Trust (“SPT”) with the Penn acquisition on December 14, 2012.

Contributions to the SPT are made currently based on a per day worked basis and charged to expense as incurred and included in costs of sales and operating expenses in the consolidated statement of earnings. During 2013 and 2012, the Company made contributions of $1,368,000 and $107,000, respectively, to the SPT and none of the Company’s contributions to the SPT exceeded 5% of total contributions to the SPT nor did the Company pay any material surcharges.

The federal identification number of the SPT is 13-6100329 and the Certified Zone Status is Green at December 31, 2013. The Company’s future minimum contribution requirements under the SPT are unavailable because actuarial reports for the 2013 plan year are not yet complete and such contributions are subject to negotiations between the employers and the unions. The SPT was neither in endangered or critical status for the 2012 plan year, the latest period for which a report is available, as the funded status was in excess of 100%. Based on an actuarial valuation performed as of December 31, 2012, there would be no withdrawal liability if the Company chose to withdraw from the SPT although the Company currently has no intention of terminating its participation in the SPT.

In addition to the defined benefit plans, the Company sponsors various defined contribution plans for substantially all employees. The aggregate contributions to the plans were $23,158,000, $22,427,000 and $13,793,000 in 2013, 2012 and 2011, respectively.

(14) Contingencies and Commitments

In June 2011, the Company as well as three other companies received correspondence from United States Environmental Protection Agency (“EPA”) concerning ongoing cleanup and restoration activities under the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) with respect to a Superfund site, the Gulfco Marine Maintenance Site (“Gulfco”), located in Freeport, Texas. In prior years, various subsidiaries of the Company utilized a successor to Gulfco to perform tank barge cleaning services, sand blasting and repair on certain Company vessels. The EPA continues to investigate activities at the site to assess additional Potentially Responsible Parties (“PRPs”). Since 2005, four named PRPs have participated in the investigation, cleanup and restoration of the site under an administrative order from EPA. Information received to date indicates that approximately $4,500,000 has been incurred in connection with the cleanup effort in addition to EPA’s oversight costs of approximately $1,800,000. To date, neither the EPA nor the named PRPs have performed an allocation of potential liability in connection with the site nor have they provided requested supporting documentation for costs and expenses related to the site. The Company is investigating its activities at the site in order to assess what, if any, liability it has in connection with the site.

In 2009, the Company was named a PRP in addition to a group of approximately 250 named PRPs under CERCLA with respect to a Superfund site, the Portland Harbor Superfund site (“Portland Harbor”) in Portland, Oregon. The site was declared a Superfund site in December 2000 as a result of historical heavily industrialized use due to manufacturing, shipbuilding, petroleum storage and distribution, metals salvaging, and electrical power generation activities which led to contamination of Portland Harbor, an urban and industrial reach of the lower Willamette River located immediately downstream of downtown Portland. The Company’s involvement arises from four spills at the site after it was declared a Superfund site, as a result of predecessor entities’ actions in the area. To date, there is no information suggesting the extent of the costs or damages to be claimed from the 250 notified PRPs. Based on the nature of the involvement at the Portland Harbor site, the Company believes its potential contribution is de minimis; however, to date neither the EPA nor the named PRPs have performed an allocation of potential liability in connection with the site nor have they provided costs and expenses in connection with the site.

In 2000, the Company and a group of approximately 45 other companies were notified that they are PRPs under CERCLA with respect to a Superfund site, the Palmer Barge Line Superfund Site (“Palmer”), located in Port Arthur, Texas. In prior years, Palmer had provided tank barge cleaning services to various subsidiaries of the Company. The Company and three other PRPs entered into an agreement with the EPA to perform a remedial investigation and feasibility study and, subsequently, a limited remediation was performed and is now complete. During the 2007 third quarter, five new PRPs entered into an agreement with the EPA related to the Palmer site. In July 2008, the EPA sent a letter to approximately 30 PRPs for the Palmer site, including the Company, indicating that it intends to pursue recovery of $2,949,000 of costs it incurred in relation to the site. The Company and the other PRPs submitted recommended pro rata allocations of costs among all PRPs to the EPA and the U.S. Department of Justice (“DOJ”) in order to resolve the EPA’s past costs claim which is under consideration by the DOJ.

With respect to the above sites, the Company has recorded reserves, if applicable, for its estimated potential liability for its portion of the EPA’s past costs claim based on information developed to date including various factors such as the Company’s liability in proportion to other responsible parties and the extent to which such costs are recoverable from third parties.
On July 25, 2011, a subsidiary of the Company was named as a defendant in the U.S. District Court for the Southern District of Texas - Galveston Division, in a complaint styled Figgs. v. Kirby Inland Marine, et al., which alleges that the plaintiff individually as a vessel tankerman, and on behalf of other current and former similarly situated vessel tankermen employed with the Company, is entitled to overtime pay under the Fair Labor Standards Act. Plaintiffs assert that vessel tankermen are not seamen who are expressly exempt from overtime pay provisions under the law. The case was conditionally certified as a collective action on December 22, 2011 at which time the Court prescribed a notice period for current and former employees to voluntarily participate as plaintiffs. The notice period closed on February 27, 2012. Plaintiffs seek compensatory damages in the form of back pay, attorneys’ fees, cost and liquidated damages. As this matter is in the initial stage of discovery as to the merits of the case, the Company is unable to assess what liability, if any, it may have.
 
In addition, the Company is involved in various legal and other proceedings which are incidental to the conduct of its business, none of which in the opinion of management will have a material effect on the Company’s financial condition, results of operations or cash flows. Management believes that it has recorded adequate reserves and believes that it has adequate insurance coverage or has meritorious defenses for these other claims and contingencies.

Certain Significant Risks and Uncertainties. The preparation of financial statements in conformity with United States generally accepted accounting principles 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. Actual results could differ from those estimates. However, in the opinion of management, the amounts would be immaterial.

The customer base of the marine transportation segment includes the major industrial petrochemical and chemical manufacturers, refining companies and agricultural chemical manufacturers operating in the United States. During 2013, approximately 75% of marine transportation’s inland revenues were from movements of such products under term contracts, typically ranging from one year to five years, with renewal options. During 2013, approximately 75% of the marine transportation’s coastal revenues were under term contracts. While the manufacturing and refining companies have generally been customers of the Company for numerous years (some as long as 40 years) and management anticipates a continuing relationship, there is no assurance that any individual contract will be renewed. No single customer of the marine transportation segment accounted for more than 10% of the Company’s revenues in 2013, 2012 and 2011.

Major customers of the diesel engine services segment include inland and offshore barge operators, oilfield service companies, oil and gas operators and producers, compression companies, offshore fishing companies, marine and on-highway transportation companies, the USCG and United States Navy, and power generation, nuclear and industrial companies. The segment operates as an authorized distributor in 17 eastern states and the Caribbean, and as non-exclusive authorized service centers for Electro-Motive Diesel, Inc. (“EMD”) throughout the rest of the United States for marine and power generation applications. The diesel engine services segment’s relationship with EMD has been maintained for 48 years. The segment also operates factory-authorized full service marine dealerships for Cummins, Detroit Diesel and John Deere high-speed diesel engines and Allison transmissions and gears in the Gulf Coast region, as well as an authorized marine dealer for Caterpillar in Alabama, Kentucky, Louisiana and New Jersey.

United has maintained continuous exclusive distribution rights for MTU and Allison since 1946. United is one of MTU’s top five distributors of MTU off-highway engines in North America with exclusive distribution rights in Oklahoma, Arkansas, Louisiana and Mississippi. In addition, as a distributor of Allison transmission products, United has distribution rights in Oklahoma, Arkansas and Louisiana. Finally, United is also the exclusive distributor for Daimler engines and related equipment, in Oklahoma, Arkansas and Louisiana.

The results of the diesel engine services segment are largely tied to the industries it serves and, therefore, can be influenced by the cycles of such industries. No single customer of the diesel engine services segment accounted for more than 10% of the Company’s revenues in 2013, 2012 and 2011.
Weather can be a major factor in the day-to-day operations of the marine transportation segment. Adverse weather conditions, such as high or low water, tropical storms, hurricanes, tsunamis, fog and ice, can impair the operating efficiencies of the marine fleet. Shipments of products can be delayed or postponed by weather conditions, which are totally beyond the control of the Company. Adverse water conditions are also factors which impair the efficiency of the fleet and can result in delays, diversions and limitations on night passages, and dictate horsepower requirements and size of tows. Additionally, much of the inland waterway system is controlled by a series of locks and dams designed to provide flood control, maintain pool levels of water in certain areas of the country and facilitate navigation on the inland river system. Maintenance and operation of the navigable inland waterway infrastructure is a government function handled by the Army Corps of Engineers with costs shared by industry. Significant changes in governmental policies or appropriations with respect to maintenance and operation of the infrastructure could adversely affect the Company.

The Company’s marine transportation segment is subject to regulation by the USCG, federal laws, state laws and certain international conventions, as well as numerous environmental regulations. The Company believes that additional safety, environmental and occupational health regulations may be imposed on the marine industry. There can be no assurance that any such new regulations or requirements, or any discharge of pollutants by the Company, will not have an adverse effect on the Company.

The Company’s marine transportation segment competes principally in markets subject to the Jones Act, a federal cabotage law that restricts domestic marine transportation in the United States to vessels built and registered in the United States, and manned and owned by United States citizens. The Jones Act cabotage provisions occasionally come under attack by interests seeking to facilitate foreign flag competition in trades reserved for domestic companies and vessels under the Jones Act. The Company believes that continued efforts will be made to modify or eliminate the cabotage provisions of the Jones Act. If such efforts are successful, certain elements could have an adverse effect on the Company.

The Company has issued guaranties or obtained standby letters of credit and performance bonds supporting performance by the Company and its subsidiaries of contractual or contingent legal obligations of the Company and its subsidiaries incurred in the ordinary course of business. The aggregate notional value of these instruments is $40,343,000 at December 31, 2013, including $6,108,000 in letters of credit and $34,235,000 in performance bonds. All of these instruments have an expiration date within four years. The Company does not believe demand for payment under these instruments is likely and expects no material cash outlays to occur in connection with these instruments.
 (15) Segment Data

The Company’s operations are classified into two reportable business segments as follows:

Marine Transportation — Marine transportation principally by United States flag vessels of liquid cargoes throughout the United States inland waterway system, along all three United States coasts, Alaska and Hawaii and, to a lesser extent, United States coastal transportation of dry-bulk cargoes. The principal products transported include petrochemicals, black oil, refined petroleum products and agricultural chemicals.

Diesel Engine Services — Provides after-market services for medium-speed and high-speed diesel engines, reduction gears and ancillary products for marine and power generation applications, and distributes and services high-speed diesel engines, transmissions, pumps and compression products, and manufactures and remanufactures oilfield service equipment, including pressure pumping units, for the land-based pressure pumping and oilfield service markets.

The Company’s two reportable business segments are managed separately based on fundamental differences in their operations. The Company’s accounting policies for the business segments are the same as those described in Note 1, Summary of Significant Accounting Policies. The Company evaluates the performance of its segments based on the contributions to operating income of the respective segments, and before income taxes, interest, gains or losses on disposition of assets, other nonoperating income, noncontrolling interests, accounting changes, and nonrecurring items. Intersegment sales for 2013, 2012 and 2011 were not significant.

The following table sets forth by reportable segment the revenues, profit or loss, total assets, depreciation and amortization, and capital expenditures attributable to the principal activities of the Company for the years ended December 31, 2013, 2012 and 2011 (in thousands):
