Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents. Includes cash and cash equivalents associated with the entity's continuing operations. Excludes cash and cash equivalents associated with the disposal group (and discontinued operation).

Represents the noncurrent portion of deferred tax liabilities, which result from applying the applicable tax rate to net taxable temporary differences pertaining to each jurisdiction to which the entity is obligated to pay income tax. A noncurrent taxable temporary difference is a difference between the tax basis and the carrying amount of a noncurrent asset or liability in the financial statements prepared in accordance with generally accepted accounting principles. In a classified statement of financial position, an enterprise separates deferred tax liabilities and assets into a current amount and a noncurrent amount. Deferred tax liabilities and assets are classified as current or noncurrent based on the classification of the related asset or liability for financial reporting. A deferred tax liability or asset that is not related to an asset or liability for financial reporting, including deferred tax assets related to carryforwards, are classified according to the expected reversal date of the temporary difference.

- Definition
Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents.

| Summary Of Significant Accounting Policies [Abstract] | |
| Summary Of Significant Accounting Policies | (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, 2011 and 2010 were $53,083,000 and $24,626,000, 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, 2011 and 2010 were $15,530,000 and $3,453,000, 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 months, unless the drydocking extends the life or improves the operating capability of the vessels which results 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, 2011 and 2010. For 2011 and 2010, 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, 2011 and 2010 was $500,935,000 and $246,340,000, respectively, and accumulated amortization at December 31, 2011 and 2010 was $15,566,000. Accumulated impairment losses were $1,901,000 at December 31, 2011 and 2010. Net goodwill for the marine transportation segment was $276,163,000 and $153,870,000 at December 31, 2011 and 2010, respectively. Net goodwill for the diesel engine services segment was $207,305,000 and $75,003,000 at December 31, 2011 and 2010, respectively. 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, up to the Company's deductible, for 2011, 2010 and 2009 were $18,673,000, $13,461,000 and $12,786,000, 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 Standards In September 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2011-08, "Testing Goodwill for Impairment." ASU 2011-08 amends the guidance in ASC 350-20, "Intangibles – Goodwill and Other – Goodwill." Under ASU 2011-08, entities have the option of performing a qualitative assessment before calculating the fair value of the reporting unit when testing goodwill for impairment. If the fair value of the reporting unit is determined, based on qualitative factors, to be more likely than not less than the carrying amount of the reporting unit, then entities are required to perform the two-step goodwill impairment test. This ASU is effective for goodwill impairment tests performed in interim and annual periods for fiscal years beginning after December 15, 2011, with early adoption permitted. The Company adopted the provisions of this ASU for its 2011 goodwill impairment testing with no impact on its consolidated financial statements. In June 2011, the FASB issued ASU 2011-05, "Comprehensive Income (Topic 220): Presentation of Comprehensive Income." ASU 2011-05 requires entities to present components of comprehensive income in either a single continuous statement of comprehensive income or two separate but consecutive statements that would include reclassification adjustments for items that are reclassified from other comprehensive income ("OCI") to net income on the face of the financial statements. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The adoption of ASU 2011-05 will not have a material impact on the Company's consolidated financial statements. In December 2011, the FASB issued ASU 2011-12, "Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05" ("ASU 2011-12"). The amendments to the Codification in ASU 2011-12 are effective at the same time as the amendments in ASU 2011-05, so that entities will not be required to comply with the presentation requirements in ASU 2011-05 that ASU 2011-12 is deferring. The amendments are being made to allow the FASB time to reevaluate whether to present on the face of the financial statements the effects of reclassifications out of accumulated OCI on the components of net income and OCI for all periods presented. ASU 2011-12 will be effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The adoption of ASU 2011-12 will not have a material impact on the Company's consolidated financial statements.

| Acquisitions | (2) Acquisitions 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 have 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 the acquisition date, K-Sea'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. K-Sea'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. K-Sea's customers include major oil companies and refiners, many of which are current Company customers for inland tank barge services. K-Sea has operating facilities in New York, Philadelphia, Seattle and Honolulu. The Company considers K-Sea to be a natural extension of the current marine transportation segment, expanding into the coastal marine transportation business from the predominately inland based marine transportation business. Total consideration transferred was as follows (in thousands):
The fair values of the assets acquired and liabilities assumed recorded at the acquisition date were as follows (in thousands):
The analysis of the K-Sea fair values above is substantially complete but all fair values have not been finalized pending obtaining the information necessary to complete the analysis. Companies have one year after an acquisition to finalize acquisition accounting under current accounting rules. As a result of the acquisition, the Company recorded $113,973,000 of goodwill and $11,400,000 of net intangibles. The net intangibles have a weighted average amortization period of approximately 11 years. The Company expects substantially all of the goodwill will be deductible for tax purposes. Acquisition and integration related costs of $5,353,000, consisting primarily of legal, audit and other professional fees plus other expenses, were expensed as incurred to selling, general and administrative expense in 2011. 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. United, headquartered in Oklahoma City, Oklahoma with 21 locations across seven states, distributes and services equipment and parts for Allison Transmission ("Allison"), MTU Detroit Diesel ("MTU"), Daimler Trucks NA ("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. The Company considers United to be a natural extension of the current diesel engine services segment, expanding into the land-based diesel engines and transmissions service business, especially the pressure pumping and oilfield services market. Total consideration transferred was as follows (in thousands):
The fair values of the assets acquired and liabilities assumed recorded at the acquisition date were as follows (in thousands):
The analysis of the United fair values above is substantially complete but all fair values have not been finalized pending obtaining the information necessary to complete the analysis. Companies have one year after an acquisition to finalize acquisition accounting under current accounting rules. As a result of the acquisition, the Company recorded $132,302,000 of goodwill and $75,697,000 of intangibles. The intangibles have a weighted average amortization period of approximately 16 years. The Company expects substantially all of the goodwill will be deductible for tax purposes. Acquisition related costs of $760,000, consisting primarily of legal and audit fees and other expenses, were expensed as incurred to selling, general and administrative expense in 2011. 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, 2009. The pro forma results do not include the acquisitions of 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, elimination of K-Sea's goodwill impairment charge in the second quarter of 2010, 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 had been consummated as of January 1, 2009 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, 2011, 2010 and 2009 (unaudited and in thousands, except per share amounts):

| Fair Value Measurements | (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, 2011 and 2010 (in thousands):
The fair value of the Company's derivative instruments is more fully described below in Note 5, Derivative Instruments. In connection with the acquisition of United on April 15, 2011, United's former owners are 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 is based on a valuation of the estimated fair value of the liability after probability weighting and discounting various potential payments. The increase in the fair value of the earnout liability of $6,300,000 for 2011 was charged to selling, general and administrative expense. As of December 31, 2011, the Company had recorded an earnout liability of $22,600,000. 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 Company is of the opinion that amounts included in the consolidated financial statements for outstanding debt materially represent the fair value of such debt due to their variable interest rates. 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, 2011 and 2010, there was no indication that the Company's long-lived assets were impaired, and accordingly, measurement at fair value was not required. |

| Derivative Instruments | (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. Special accounting for derivatives qualifying as fair value hedges allows a derivative's gains and losses to offset related results on the hedged item in the statement of earnings. 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 and expects to continue to utilize 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. Derivative financial instruments related to the Company's interest rate risks are intended to reduce the Company's exposure to increases in the benchmark interest rates underlying the Company's floating rate senior notes, variable rate term loan and variable rate bank revolving credit facility.
From time to time, the Company hedges its exposure to fluctuations in short-term interest rates under its variable rate bank revolving credit facility and floating rate senior notes by entering into interest rate swap agreements. The interest rate swap agreements are designated as cash flow hedges, therefore, the changes in fair value, to the extent the swap agreements are effective, are recognized in OCI until the hedged interest expense is recognized in earnings. The current swap agreements effectively convert the Company's interest rate obligation on the Company's variable rate senior notes from quarterly floating rate payments based on the London Interbank Offered Rate ("LIBOR") to quarterly fixed rate payments. As of December 31, 2011, the Company had a total notional amount of $200,000,000 of interest rate swaps designated as cash flow hedges for its variable rate senior notes as follows (dollars in thousands):
Foreign Currency Risk Management From time to time, the Company has utilized and expects to continue to utilize 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, 2011, the Company had forward contracts with notional amounts aggregating $5,406,000 to hedge its exposure to foreign currency rate fluctuations in expected foreign currency transactions. These contracts expire on various dates beginning in the first quarter of 2012 and ending in the first quarter of 2014. These forward contracts are designated as cash flow hedges, therefore, the changes in fair value, to the extent the forward contracts are effective, are recognized in OCI until the forward contracts expire and are recognized in cost of sales and operating expenses. Fair Value of Derivative Instruments The following table sets forth the fair value of the Company's derivative instruments recorded as liabilities located on the consolidated balance sheet at December 31, 2011 and 2010 (in thousands):
Fair value amounts were derived as of December 31, 2011 and 2010 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, 2011, 2010 and 2009 (in thousands):
The Company anticipates $4,781,000 of net losses on interest rate swap agreements included in accumulated OCI will be transferred into earnings over the next year based on current interest rates. Gains or losses on interest rate swap agreements offset increases or decreases in rates of the underlying debt, which results in a fixed rate for the underlying debt. The Company also expects $211,000 of net losses on foreign currency contracts included in accumulated OCI will be transferred into earnings over the next year based on current spot rates. |

On May 31, 2011, the Company entered into 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 a base rate calculated with reference to the agent bank's prime rate, among other factors (the "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. The primary purpose of the Term Loan was to provide financing for the Company's acquisition of K-Sea. The acquisition of K-Sea was completed and the Term Loan funded on July 1, 2011. As of December 31, 2011, the Company was in compliance with all Term Loan covenants and had $507,000,000 outstanding under the Term Loan, $39,000,000 of which was classified as current portion of long-term debt. The Term Loan's average interest rate for 2011 was 1.8%, computed by dividing the interest expense under the Term Loan by the average Term Loan borrowings. The Company has an 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 Revolving Credit Facility allows for an increase in the commitments of the banks from $250,000,000 up to a maximum of $325,000,000, subject to the consent of each bank that elects to participate in the increased commitment. On May 31, 2011, the Revolving Credit Facility was amended to conform the interest rate spread to the spread provided in the Term Loan described above. The unsecured Revolving Credit Facility has a variable interest rate based on LIBOR or an Alternate Base Rate. The variable interest rate spread varies with the Company's senior debt rating. The variable interest rate spread is currently 1.5% over LIBOR for LIBOR loans and 0.5% over the Alternate Base Rate for Alternate Base Rate loans. 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, 2011, the Company was in compliance with all Revolving Credit Facility covenants and had $95,000,000 outstanding under the Revolving Credit Facility. The average borrowing under the Revolving Credit Facility during 2011 was $59,608,000, computed by averaging the daily balance, and the weighted average interest rate was 1.9%, 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 $2,440,000 as of December 31, 2011.
The Company has $200,000,000 of unsecured floating rate senior notes ("Senior Notes") due February 28, 2013. The Senior Notes pay interest quarterly at a rate equal to LIBOR plus a margin of 0.5%. The Senior Notes are callable, at the Company's option, at par. No principal payments are required until maturity in February 2013. As of December 31, 2011, $200,000,000 was outstanding under the Senior Notes and the 2011 average interest rate was 0.8%, computed by dividing the interest expense under the Senior Notes by the average Senior Notes borrowings of $200,000,000. The Company was in compliance with all Senior Notes covenants at December 31, 2011. 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 30, 2012. 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 did not have any borrowings outstanding under the Credit Line as of December 31, 2011. Outstanding letters of credit under the Credit Line were $4,093,000 as of December 31, 2011. The Company is of the opinion that the amounts included in the consolidated financial statements for outstanding debt materially represent the fair value of such debt at December 31, 2011 and 2010 due to their variable interest rates. |

| Taxes On Income | (7) Taxes on Income Earnings before taxes on income and details of the provision for taxes on income for the years ended December 31, 2011, 2010 and 2009 were as follows (in thousands):
During the three years ended December 31, 2011, 2010 and 2009, tax benefits related to the exercise of stock options and the issuance of restricted stock that were allocated directly to additional paid-in capital were $1,348,000, $373,000 and $1,013,000, respectively. The Company's provision for taxes on income varied from the statutory federal income tax rate for the years ended December 31, 2011, 2010 and 2009 due to the following:
The tax effects of temporary differences that give rise to significant portions of the current deferred tax assets and non-current deferred tax assets and liabilities at December 31, 2011 and 2010 were as follows (in thousands):
The Company has determined that it is more likely than not that all deferred tax assets at December 31, 2011 will be realized, including its operating loss carryforwards of $1,305,000 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 2008 through 2010 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 2005 through 2010 tax years. As of December 31, 2011, the Company has provided a liability of $2,509,000 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 $1,775,000, 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, 2012 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, 2011, 2010 and 2009, is as follows (in thousands):
The Company accounts for interest and penalties related to uncertain tax positions as part of its provision for federal and state income taxes. The Company recognized net expense (income) of $16,000, $43,000 and $(221,000) in interest and penalties for the years ended December 31, 2011, 2010 and 2009, respectively. The Company had $977,000, $993,000 and $964,000 of accrued liabilities for the payment of interest and penalties at December 31, 2011, 2010 and 2009, respectively. |

| Retirement Plans | (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 $174,223,000 and $152,696,000 at December 31, 2011 and 2010, respectively. As of December 31, 2011 and 2010, these assets were allocated among asset categories as follows:
The cash and cash equivalents asset category exceeded the maximum percentage allocation in 2011 due to the 2011 pension plan contribution of $27,500,000 being funded on the last day of 2011 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 2012.
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 2011 and 2010. 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 contribution of $27,500,000 in December 2011 resulted in funding 97% of the pension plan's ABO at December 31. 2011. 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.

| Contingencies And Commitments [Abstract] | |
| Contingencies And Commitments | (13) 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 $3,500,000 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 cost and expenses supporting documentation 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 noticed 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 the 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 continue to discuss suggested pro rata allocations of costs to all PRPs with the EPA and the U.S. Department of Justice ("DOJ") in order to resolve the EPA's past costs claim. In 2000, the Company and approximately 50 other companies were notified that they are PRPs under the CERCLA with respect to a Superfund site, the State Marine of Port Arthur Superfund Site ("State Marine"), located in Port Arthur, Texas. In the past, State Marine performed tank barge cleaning and services for various subsidiaries of the Company. In March 2010, the DOJ and EPA issued a letter to seven PRPs, which include the former owners/operator of the site and others, including the Company, indicating their intent to pursue reimbursement of its past costs of approximately $2,977,000 in connection with clean-up activities in relation to the site. The Company and the other PRPs will continue to pursue documentation concerning the site activities related to all PRPs in order to determine appropriate allocation of past costs relative to activities at the site to develop suggested pro rata sharing to resolve the EPA's past cost claim. 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 tankerman employed with the Company, is entitled to overtime pay under the Fair Labor Standards Act. Plaintiffs assert that vessel tankerman are not seaman 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 a plaintiff. The notice period closes on February 27, 2012 after which time discovery will be conducted with respect to the merits of the case. Plaintiff seeks to maintain a collective action, compensatory damages in the form of back pay, attorneys fees, cost and liquidated damages. As discovery as to the merits of the case has not been conducted to date, the Company is unable to assess the liability at this time. Accordingly, the Company is not able to estimate any amount of loss or range of loss. On January 30, 2012 in the U.S. District Court for the District of New Jersey and styled Rescue Mission of El Paso., Inc., et al. v. John J. Nicola, et al., the Company, its subsidiary, K-Sea and current and former officers and directors of K-Sea were named defendants in a putative class action complaint asserting that during the period of January 30, 2009 to January 27, 2010, K-Sea allegedly failed to disclose certain facts regarding K-Sea's operations and financial conditions, and asserting violations of Sections 10(b)(5) and 20(a) of the Securities and Exchange Act of 1934 and Rule 10b-5 thereunder. Plaintiff seeks class certification, compensatory damages, attorneys fees and costs. The Company believes that this suit is without merit and intends to vigorously defend itself in this matter based on the information available to the Company at this time. The Company does not expect the outcome of this matter to have a material adverse effect on its consolidated financial statements; however, there can be no assurance as to the ultimate outcome of this matter. 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, agricultural chemical manufacturers and refining companies operating in the United States. During 2011, approximately 75% of marine transportation's inland revenues were from movements of such products under term contracts, ranging from one year to five years, with renewal options. During the second half of 2011, approximately 60% 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 2011. The Dow Chemical Company accounted for 12% of the Company's revenues in 2010 and 11% in 2009. SeaRiver Maritime, Inc., the United States transportation affiliate of Exxon Mobil Corporation, accounted for 11% of the Company's revenues in 2010 and 10% in 2009. 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 46 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 and Louisiana. 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 2011, 2010 and 2009. 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 $26,329,000 at December 31, 2011, including $9,260,000 in letters of credit and debt guarantees, and $17,069,000 in performance bonds. All of these instruments have an expiration date within three 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. |

| Segment Data | (14) Segment Data The Company's operations are classified into two reportable business segments as follows: Marine Transportation — Marine transportation 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 products, refined petroleum products and agricultural chemicals. Diesel Engine Services — Overhaul and repair of medium-speed and high-speed diesel engines, reduction gear repair, and sale of related parts and accessories for customers in the marine and power generation applications, and distribution and service of high-speed diesel engines, transmissions, including the manufacture and remanufacture of hydraulic fracturing equipment for 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 2011, 2010 and 2009 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, 2011, 2010 and 2009 (in thousands):

| Summary Of Significant Accounting Policies [Abstract] | |
| Principles Of Consolidation | 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. |
| Cash Equivalents | 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 | 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, 2011 and 2010 were $53,083,000 and $24,626,000, 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, 2011 and 2010 were $15,530,000 and $3,453,000, respectively, of receivables from insurance companies to cover claims in excess of the Company's deductible. |
| Concentrations Of Credit Risk | 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 | 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, 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 | 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 months, unless the drydocking extends the life or improves the operating capability of the vessels which results in the costs being capitalized. Routine repairs and maintenance on ocean-going vessels are expensed as incurred. |
| Environmental Liabilities | Environmental Liabilities. The Company expenses costs related to environmental events as they are incurred or when a loss is considered probable and estimable. |
| Goodwill | 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, 2011 and 2010. For 2011 and 2010, 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, 2011 and 2010 was $500,935,000 and $246,340,000, respectively, and accumulated amortization at December 31, 2011 and 2010 was $15,566,000. Accumulated impairment losses were $1,901,000 at December 31, 2011 and 2010. Net goodwill for the marine transportation segment was $276,163,000 and $153,870,000 at December 31, 2011 and 2010, respectively. Net goodwill for the diesel engine services segment was $207,305,000 and $75,003,000 at December 31, 2011 and 2010, respectively. |
| Revenue Recognition | 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 | 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 | 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. 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, up to the Company's deductible, for 2011, 2010 and 2009 were $18,673,000, $13,461,000 and $12,786,000, respectively. |
| Noncontrolling Interests | 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 | 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 | 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. |
