NOTES TO CONDENSED FINANCIAL STATEMENTS

(Unaudited)

In the opinion of management, the accompanying unaudited condensed financial statements of Kirby Corporation and consolidated subsidiaries (the “Company”) contain all adjustments (consisting of only normal recurring accruals) necessary to present fairly the financial position as of September 30, 2010 and December 31, 2009, and the results of operations for the three months and nine months ended September 30, 2010 and 2009.

(1)

BASIS FOR PREPARATION OF THE CONDENSED FINANCIAL STATEMENTS

The condensed financial statements included herein have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Although the Company believes that the disclosures are adequate to make the information presented not misleading, certain information and footnote disclosures, including significant accounting policies normally included in annual financial statements, have been condensed or omitted pursuant to such rules and regulations. It is suggested that these condensed financial statements be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2009.

(2)

ACCOUNTING ADOPTION

In January 2010, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2010-06, “Improving Disclosures about Fair Value Measurements”. ASU 2010-06 requires additional disclosures about fair value measurements including transfers in and out of Levels 1 and 2 as well as the reasons for the transfers and a greater level of disaggregation for each class of assets and liabilities. For the reconciliation of Level 3 fair value measurements, information about purchases, sales, issuances and settlements are presented separately rather than one net number. This standard is effective for interim and annual reporting periods beginning after December 15, 2009 with the exception of revised Level 3 disclosure requirements which are effective for interim and annual reporting periods beginning after December 15, 2010. The Company applied the provisions of this standard to its financial statement disclosures beginning in the first quarter of 2010.

(3)

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.

FAIR VALUE MEASUREMENTS — (CONTINUED)

The following table summarizes the assets and liabilities measured at fair value on a recurring basis at September 30, 2010 (in thousands):


	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total Fair Value Measurements
Assets:
Derivatives	$	—	$	5	$	—	$	5

Liabilities:
Derivatives	$	—	$	20,583	$	—	$	20,583

The following table summarizes the assets and liabilities measured at fair value on a recurring basis at December 31, 2009 (in thousands):


	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total Fair Value Measurements
Assets:
Derivatives	$	—	$	138	$	—	$	138

Liabilities:
Derivatives	$	—	$	15,301	$	—	$	15,301

The fair value of the Company’s derivative instruments is more fully described below in Note 4, Derivative Instruments.

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 nine months ended September 30, 2010, there was no indication that the Company’s long-lived assets were impaired, and accordingly, measurement at fair value was not required.

(4)

DERIVATIVE INSTRUMENTS

The Company recognizes all derivative instruments (including certain derivative instruments embedded in other contracts) 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,

KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES

NOTES TO CONDENSED FINANCIAL STATEMENTS—(Continued)

(Unaudited)

(4)

DERIVATIVE INSTRUMENTS — (CONTINUED)

changes in fair value, to the extent the hedge is effective, are recognized in other comprehensive income (“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 collar and 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 and variable rate bank credit facility.

From time to time, the Company hedges its exposure to fluctuations in short-term interest rates under its variable rate bank credit facility and floating rate senior notes by entering into interest rate collar and swap agreements. The interest rate collar and swap agreements are designated as cash flow hedges, therefore, the changes in fair value, to the extent the collar and swap agreements are effective, are recognized in OCI until the hedged interest expense is recognized in earnings. The 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 September 30, 2010, 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):


Notional Amount	Effective date	Termination date	Fixed pay rate	Receive rate
$ 100,000	March 2006	February 2013	5.45%	Three-month LIBOR
$ 50,000	November 2008	February 2013	3.50%	Three-month LIBOR
$ 50,000	May 2009	February 2013	3.795%	Three-month LIBOR

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.

KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES

NOTES TO CONDENSED FINANCIAL STATEMENTS—(Continued)

(Unaudited)

(4)

DERIVATIVE INSTRUMENTS — (CONTINUED)

As of September 30, 2010, the Company has forward contracts with notional amounts aggregating $15,537,000 to hedge its exposure to foreign currency rate fluctuations in expected foreign currency transactions. These contracts expire on various dates beginning in the fourth quarter of 2010 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 assets on the consolidated balance sheet at September 30, 2010 and December 31, 2009 (in thousands):


Asset Derivatives	Balance Sheet Location		September 30, 2010		December 31, 2009

The following table sets forth the fair value of the Company’s derivative instruments recorded as liabilities on the consolidated balance sheet at September 30, 2010 and December 31, 2009 (in thousands):


Liability Derivatives	Balance Sheet Location		September 30, 2010		December 31, 2009

Total derivatives designated as hedging instruments under ASC 815			$	20,583	$	15,301

Total liability derivatives			$	20,583	$	15,301

Fair value amounts were derived as of September 30, 2010 and December 31, 2009 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 3, Fair Value Measurements.

DERIVATIVE INSTRUMENTS — (CONTINUED)

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 three months and nine months ended September 30, 2010 and 2009 (in thousands):

The Company anticipates $5,214,000 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 $498,000 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.

The Company has two employee stock award plans for selected officers and other key employees which provide for the issuance of stock options and restricted stock. For both of the plans, the exercise price for each option equals the fair market value per share of the Company’s common stock on the date of grant. The terms of the options granted prior to January 25, 2010 are five years and vest ratably over three years. Options granted on or after January 25, 2010 have terms of seven years and vest ratably over three years. At September 30, 2010, 1,454,352 shares were available for future grants under the employee plans and no outstanding stock options under the employee plans were issued with stock appreciation rights.

The following is a summary of the stock option activity under the employee plans described above for the nine months ended September 30, 2010:

The Company has two director stock award plans for nonemployee directors of the Company which provide for the issuance of stock options and restricted stock. No additional options can be granted under one of the plans. The 2000 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. In addition, the 2000 Director Plan allows for the issuance of stock options or restricted stock in lieu of cash for all or part of the annual director fee at the option of the director. The exercise prices for all options granted under the plans 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 when first elected a director vest immediately. The options granted and restricted stock issued after each annual meeting of stockholders vest six months after the date of grant. Options granted and restricted stock issued in lieu of cash director fees vest in equal quarterly increments during the year to which they relate. At September 30, 2010, 324,766 shares were available for future grants under the 2000 Director Plan. The director stock award plans are intended as an incentive to attract and retain qualified and competent independent directors.

RETIREMENT PLANS

The Company sponsors a defined benefit plan for 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 2009 for the 2009 year as assets of the pension plan were 107% of the plan’s ABO at December 31, 2009. 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. Based on current pension plan assets and market conditions, the Company expects to contribute between $15,000,000 and $25,000,000 to its pension plan prior to December 31, 2010 to fund its 2010 pension plan obligations. As of September 30, 2010, no 2010 year contributions have been made.

The Company sponsors an unfunded defined benefit health care plan that provides limited postretirement medical benefits to employees who meet 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 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 components of net periodic benefit cost for the Company’s defined benefit plans for the three months and nine months ended September 30, 2010 and 2009 were as follows (in thousands):

CONTINGENCIES

In 2000, the Company and a group of approximately 45 other companies were notified that they are Potentially Responsible Parties (“PRPs”) under the Comprehensive Environmental Response, Compensation and Liability Act (“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 United States Environmental Protection Agency (“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 PRP’s entered into an agreement with the EPA in regards 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 all PRPs with the EPA and the U.S. Department of Justice in order to resolve the EPA’s past cost 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 had performed tank barge cleaning and services for various subsidiaries of the Company. In March 2010, the Department of Justice 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 $2,902,000 in connection with clean-up activities in relation to the site. The Company and the other PRPs have requested 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 its best estimate for 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.

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.

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 $26,517,000 at September 30, 2010, including $7,323,000 in letters of credit and debt guarantees, and $19,194,000 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.

Management’s Discussion and Analysis of Financial Condition and Results of Operations

Statements contained in this Form 10-Q that are not historical facts, including, but not limited to, any projections contained herein, are forward-looking statements and involve a number of risks and uncertainties. Such statements can be identified by the use of forward-looking terminology such as “may,” “will,” “expect,” “anticipate,” “estimate,” or “continue” or the negative thereof or other variations thereon or comparable terminology. The actual results of the future events described in such forward-looking statements in this Form 10-Q could differ materially from those stated in such forward-looking statements. Among the factors that could cause actual results to differ materially are: adverse economic conditions, industry competition and other competitive factors, adverse weather conditions such as high water, low water, tropical storms, hurricanes, fog and ice, marine accidents, lock delays, fuel costs, interest rates, construction of new equipment by competitors, government and environmental laws and regulations, and the timing, magnitude and number of acquisitions made by the Company. For a more detailed discussion of factors that could cause actual results to differ from those presented in forward-looking statements, see Item 1A-Risk Factors found in the Company’s annual report on Form 10-K for the year ended December 31, 2009. Forward-looking statements are based on currently available information and the Company assumes no obligation to update any such statements.

For purposes of the 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 the three months and nine months ended September 30, 2010 and 2009 were as follows:

53,337

The increase in the weighted average number of common shares for both 2010 periods compared with the 2009 periods primarily reflected the issuance of restricted stock and the exercise of stock options, partially offset by common stock repurchases in the 2010 second and third quarters.

Overview

The Company is the nation’s largest domestic inland tank barge operator with a fleet of 850 active tank barges, including 52 leased barges, with 16.4 million barrels of capacity as of September 30, 2010. The Company operated an average of 217 inland towing vessels during the 2010 third quarter, of which an average of 50 was chartered. The Company uses the United States inland waterway system to transport bulk liquids including petrochemicals, black oil products, refined petroleum products and agricultural chemicals. The Company also owns and operates four ocean-going barge and tug units transporting dry-bulk commodities in United States coastwise trade. Through its diesel engine services segment the Company provides after-market services for medium-speed and high-speed diesel engines used in marine, power generation and railroad applications.

For the 2010 third quarter, net earnings attributable to Kirby were $30,687,000, or $.57 per share, on revenues of $281,317,000, compared with 2009 third quarter net earnings attributable to Kirby of $35,014,000, or $.65 per share, on revenues of $272,166,000. For the 2010 first nine months, net earnings attributable to Kirby were $84,629,000, or $1.56 per share, on revenues of $823,239,000, compared with the 2009 first nine months net earnings attributable to Kirby of $96,739,000, or $1.79 per share, on revenues of $822,570,000.

KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES

Marine Transportation

For the 2010 third quarter and first nine months, 83% 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 raw materials for many of the end products used widely by businesses and consumers – plastics, fiber, paints, detergents, oil additives and paper, among others. Consequently, the Company’s business tends to mirror the general performance of the United States economy and volumes produced by the Company’s customer base, enhanced by the inherent efficiencies of barge transportation which is generally the lowest cost mode of surface transportation.

The Company’s marine transportation segment’s revenue for the 2010 third quarter and first nine months increased 2% and 3%, respectively, compared with revenue for the 2009 third quarter and first nine months. The segment’s operating income for the third quarter and first nine months of 2010 decreased 11% and 9%, respectively, when compared with operating income for the 2009 third quarter and first nine months. The higher marine transportation revenues reflected an improvement in tank barge demand and equipment utilization due to higher production volumes from United States petrochemical customers in the second and third quarters and anomalies impacting refinery customers in the 2010 third quarter. In addition, diesel fuel prices for the 2010 third quarter and first nine months increased 15% and 35%, respectively, compared with the 2009 third quarter and first nine months, thereby positively impacting marine transportation revenues as fuel is escalated and de-escalated through revenue adjustment clauses in customers’ term contracts. Offsetting the improved demand and higher equipment utilization was the negative impact of lower term contract and spot contract rates negotiated throughout 2009 and the first half of 2010 due to recessionary pressure and resulting lower industry-wide demand.

During the 2010 third quarter and first nine months, approximately 75% of the marine transportation revenues were under term contracts and 25% were spot contract revenues. Time charters, which insulate the Company from revenue fluctuations caused by weather and navigational delays and temporary market declines, represented 52% and 51%, respectively, of the revenues under term contracts during the 2010 third quarter and first nine months compared with 54% and 56%, respectively, during the 2009 third quarter and first nine months. Rates on term contracts renewed in the 2010 third quarter were relatively flat compared with the 2010 first and second quarters, as well as relatively flat compared with the 2009 third quarter. Spot contract rates for the 2010 third quarter, which include the cost of fuel, were relatively flat to slightly positive compared with the 2010 second quarter. Effective January 1, 2010, annual escalators for labor and the producer price index on a number of multi-year contracts were neutral.

The marine transportation operating margin for the 2010 third quarter was 22.1% compared with 25.3% for the 2009 third quarter and 21.0% for the 2010 first nine months compared with 23.6% for the 2009 first nine months. The lower operating margins reflected the impact of lower term contract and spot contract pricing negotiated throughout the 2009 year and the 2010 first half, higher fuel costs and increased delay days, partially offset by higher tank barge utilization in the petrochemical market during the 2010 second and third quarters and black oil market in the 2010 third quarter, and by the cost reduction initiatives implemented during 2009 and in the 2010 first quarter.

Diesel Engine Services

For the 2010 third quarter and first nine months, 17% of the Company’s revenue was generated by the diesel engine services segment, of which 64% was generated through service and 36% from direct parts sales. The results of the diesel engine services segment are largely influenced by the economic cycles of the marine, power generation and railroad industries it serves.

The Company’s diesel engine services segment’s 2010 third quarter revenue increased 9% and operating income decreased 3% compared with the third quarter of 2009. For the first nine months of 2010, revenues and operating income decreased 11% and 21%, respectively, compared with the 2009 first nine months. The medium-speed power generation market for the 2010 third quarter was stronger, positively impacted by additional engine-generator set upgrades and higher parts and engines sales, accounting for the higher 2010 third quarter revenue compared with the 2009 third quarter. Demand levels for service and direct parts sales across the majority of the marine markets, particularly the Gulf Coast oil services market, remained weak during the 2010 third quarter and first nine months, resulting from customers’ continued deferral of major maintenance projects. In addition, the moratorium on Gulf of Mexico deep water drilling negatively impacted both the Gulf Coast medium-speed and high-speed operations during the 2010 second and third quarters. Partially offsetting the weaknesses in the marine market was required repair work for customers involved in the Gulf Coast oil spill cleanup.

The diesel engine services segment’s operating margin for the 2010 third quarter was 9.3% compared with 10.4% for the third quarter of 2009. For the 2010 first nine months, the operating margin was 9.7% compared with 10.9% for the 2009 first nine months. Both 2010 periods reflected overall lower service and direct parts sales, excluding the power generation market as noted above, some pricing pressure in the high-speed marine markets and lower labor utilization, partially offset by the positive impact of the 2009 cost reduction initiatives. The 2009 first nine months operating margin was negatively impacted by a first quarter charge for early retirements and staff reductions of $1,426,000.

Cash Flow and Capital Expenditures

The Company continued to generate strong operating cash flow during the 2010 first nine months, with net cash provided by operating activities of $169,837,000 compared with net cash provided by operating activities for the 2009 first nine months of $237,101,000. The 2010 first nine months experienced a net decrease in cash flows from changes in operating assets and liabilities of $22,874,000, primarily due to a federal income tax receivable as of September 30, 2010 of $25,169,000, the result of the recently enacted Small Business Jobs Act of 2010 that included a one-year extension of bonus tax depreciation on qualified property. This extension was granted after the Company’s estimated tax payment was made on September 15, 2010, based on the assumption that bonus tax depreciation would not be extended and, as a result, the Company overpaid its 2010 estimated federal income taxes. This compares with a net increase in the 2009 first nine months of $31,964,000, primarily due to a decrease in receivables in the 2009 first nine months resulting from decreased revenues due to weaker business activity levels. In addition, during the 2010 and 2009 first nine months, the Company generated cash of $3,824,000 and $2,056,000, respectively, from the exercise of stock options, and $7,501,000 and $3,619,000, respectively, from proceeds from the disposition of assets.

For the 2010 first nine months, cash generated was used for capital expenditures of $108,036,000, including $60,330,000 for new tank barge and towboat construction and $47,706,000 primarily for upgrading the existing marine transportation fleet, and $20,584,000 for the repurchase of the Company’s

KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES

common stock. The Company’s debt-to-capitalization ratio decreased to 15.1% at September 30, 2010 from 15.9% at December 31, 2009, primarily due to the increase in equity from net earnings attributable to Kirby for the 2010 first nine months of $84,629,000, exercise of stock options and the amortization of unearned equity compensation, partially offset by treasury stock purchases. As of September 30, 2010, the Company had no outstanding balance under its $250,000,000 revolving credit facility and had $149,204,000 of cash and cash equivalents.

The Company projects that capital expenditures for 2010 will be in the $135,000,000 to $145,000,000 range, including approximately $70,000,000 for new tank barge and towboat construction, taking advantage of current attractive tank barge construction prices, and prepayments on 2011 new tank barge construction. For 2010, new construction commitments consist of 58 tank barges, three 1800 horsepower towboats and prepayments on 2011 tank barge construction. New construction capital expenditures for 2011 are currently projected in the $50,000,000 to $60,000,000 range based on current commitments for 31 new tank barges, current steel prices and projected delivery schedules.

Outlook

The Company’s strong cash flow and unutilized loan facilities position the Company to take advantage of internal and external growth opportunities in its marine transportation and diesel engine services segments. The marine transportation segment’s external growth opportunities include potential acquisitions of independent operators and captive fleet owners seeking to outsource their requirements. Increasing the fleet size would allow the Company to improve fleet productivity through more backhaul opportunities, faster barge turnarounds, more efficient use of horsepower, barges positioned closer to cargoes, less cleaning due to operating more barges with compatible prior cargoes, lower incremental costs due to enhanced purchasing power and minimal incremental administrative staff. The diesel engine services segment’s external growth opportunities include further consolidation of strategically located diesel service providers, and expanded service capability for other engine and marine gear related products.

Petrochemical and black oil tank barge utilization levels on the Gulf Intracoastal Waterway and into the Midwest improved during the 2010 first nine months compared with the 2009 year, a year of economic recession. While improvement in utilization levels in these markets is encouraging, the continued sluggish United States economy, consistent high unemployment levels, negative consumer confidence, current excess industry tank barge capacity, and the continued negative impact of pending safety regulations enacted on Gulf of Mexico drillers and its unknown impact on the diesel engine services segment leaves the Company’s outlook for the balance of 2010 and into 2011 unclear.

In regard to the current excess industry tank barge capacity, during 2009 some incremental capacity was added to the industry fleet with a reported 192 tank barges constructed and delivered. The Company estimates that 140 tank barges were scrapped during 2009, for a net addition to the industry fleet of approximately 50 tank barges. At the beginning of 2010, the Company estimates there were approximately 3,150 tank barges in the industry fleet, of which approximately 500 were over 35 years old and approximately 250 of those over 40 years old. For 2010, the Company estimates that less than 100 tank barges will be constructed, of which 58 were ordered by the Company. Given the age profile of the industry fleet and current industry-wide excess tank barge capacity, the Company expects older barges will continue to be removed from service and the industry’s supply versus demand will continue to slowly move closer to balance.

Results of Operations

The Company reported 2010 third quarter net earnings attributable to Kirby of $30,687,000, or $.57 per share, on revenues of $281,317,000, compared with 2009 third quarter net earnings attributable to Kirby of $35,014,000, or $.65 per share, on revenues of $272,166,000. Net earnings attributable to Kirby for the 2010 first nine months were $84,629,000, or $1.56 per share, on revenues of $823,239,000, compared with $96,739,000, or $1.79 per share, on revenues of $822,570,000 for the 2009 first nine months.

The following table sets forth the Company’s marine transportation and diesel engine services revenues for the 2010 third quarter compared with the third quarter of 2009, the first nine months of 2010 compared with the first nine months of 2009 and the percentage of each to total revenues for the comparable periods (dollars in thousands):

As a result of the lower demand during the 2008 fourth quarter and 2009 year in both the marine transportation and diesel engine services segments, the Company took specific steps during 2009 to reduce overhead and lower expenditures, including a reduction in its shore staff. During the 2010 first quarter, the Company continued its cost reduction initiatives by further reducing its marine transportation and corporate overhead costs through retirements and staff reductions, incurring a charge of $4,072,000 before taxes, or $.05 per share. Since its peak headcount in October 2008, the Company has reduced its shore staff by 24% through retirements, staff reductions and employee attrition.

Marine Transportation

The Company, through its marine transportation segment, is a provider of marine transportation services, operating inland tank barges and towing vessels, transporting petrochemicals, black oil products, refined petroleum products and agricultural chemicals along the United States inland waterways. As of September 30, 2010, the Company operated 850 active inland tank barges, with a total capacity of 16.4 million barrels, compared with 874 active inland tank barges at September 30, 2009, with a total capacity of 16.8 million barrels. The Company operated an average of 217 active inland towing vessels during the 2010 third quarter and 221 during the 2010 first nine months compared with 215 during the third quarter of 2009 and 222 during the first nine months of 2009. The Company owns and operates four offshore dry-bulk barge and tug units engaged in the offshore transportation of dry-bulk cargoes. The Company also owns a two-thirds interest in Osprey Line, L.L.C., which transports cargo containers and project cargoes by barge on the United States inland waterway system.

KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES

Marine transportation revenues for the 2010 third quarter and first nine months increased 2% and 3%, respectively, compared with the 2009 third quarter and first nine months, reflecting an improvement in tank barge demand and equipment utilization due to higher production volumes from United States petrochemical customers and anomalies impacting refinery customers. In addition, diesel fuel prices for the 2010 third quarter and first nine months increased 15% and 35%, respectively, compared with the 2009 third quarter and first nine months, thereby positively impacting marine transportation revenues.

The petrochemical market, the Company’s largest market, contributed 69% of the marine transportation revenue for the 2010 first nine months. During the 2010 first nine months, petrochemical transportation demand reflected a continued improvement in business levels, driven by higher United States petrochemical volumes. The 2010 first quarter’s improvement was also attributable to supply chain disruptions caused by petrochemical turnarounds and unscheduled plant maintenance. Lower domestic natural gas prices have improved the global competitiveness of the United States petrochemical business in the global markets, thereby producing increased marine transportation volumes for basic petrochemicals to both domestic consumers and terminals for export destinations. As a result of the higher volumes, the Company’s petrochemical tank barge fleet’s utilization level was in the high 80% range in both the 2010 second and third quarters. The black oil products market, which contributed 18% of 2010 first nine months marine transportation revenue, saw lower utilization of the fleet, as well as a heavy shipyard maintenance cycle for black oil barges during the 2010 first half. During the 2010 third quarter, a heavy United States refinery maintenance schedule which required additional black oil shipments between refineries, coupled with the exportation of heavy fuel to South America and the Pacific Rim, resulted in the Company’s black oil fleet maintaining a high 80% range utilization level. The refined petroleum products market, which contributed 8% of 2010 first nine months marine transportation revenue, reflected continued lower demand for movements of products, consistent with prevailing conditions in the United States economy, partially offset by an improvement of river ethanol volumes. The agricultural chemical market, which contributed 5% of 2010 first nine months marine transportation revenue, was weak during the first quarter due to high Midwest inventory levels, fueled by heavy rain and snow which reduced the farmer’s ability to apply fertilizer, improved in the second quarter with the Midwest spring fill, but declined significantly in the third quarter with a worldwide shortage of fertilizer.

For the third quarter of 2010, the marine transportation segment incurred 1,006 delay days, 46% more than the 2009 third quarter delay days of 688. For the 2010 first nine months, 4,274 delay days occurred, 26% more than the 3,393 delay days that occurred in the 2009 first nine months. 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. The 2010 third quarter and first nine months delay days reflected more normal weather and lock conditions, including ice and high water conditions during portions of the first and second quarters and numerous delays from scheduled lock repairs during the third quarter. This compares with the 2009 third quarter and first nine months that experienced milder winter weather conditions and favorable water levels. The higher 2010 delay days led to increased operating expenses compared with 2009.

During the 2010 third quarter and first nine months, approximately 75% of marine transportation revenues were under term contracts and 25% were spot contract revenues, compared with 80% under term contracts and 20% under spot contracts during the 2009 third quarter and first nine months. The percentage applicable to term contracts declined beginning in the fourth quarter of 2009 as certain

KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES

customers switched to spot contracts, and in some cases, short-term charters when their term contracts expired. Time charters, which insulate the Company from revenue fluctuations caused by weather and navigational delays and temporary market declines, represented 52% and 51% of the revenues under term contracts during the 2010 third quarter and first nine months compared with 54% and 56% in the 2009 third quarter and first nine months, respectively.

Rates on term contracts renewed in the 2010 first quarter generally decreased an average of approximately 10% when compared with term contract renewals in the first quarter of 2009. Rates on term contracts renewed in the 2010 second quarter were relatively flat with the 2010 first quarter renewals, but when compared with the 2009 second quarter declined an average of 10% to 12%. For the 2010 third quarter, term contract renewals were relatively flat with the 2010 first and second quarters, as well as relatively flat compared with the 2009 third quarter. Spot contract rates for the 2010 first quarter, which include the cost of fuel, were up an average of 3% to 6% when compared with the 2009 fourth quarter, but down an average of 15% to 25% compared with the 2009 first quarter. Spot contract rates for the 2010 second quarter were relatively flat when compared with the 2010 first quarter, but when compared with the 2009 second quarter were down an average of 10% to 15%. Spot contract rates for the 2010 third quarter were relatively flat to slightly positive compared with the 2010 second quarter. Effective January 1, 2010, annual escalators for labor and the producer price index on a number of multi-year contracts were neutral.

Marine Transportation Costs and Expenses

Costs and expenses for the 2010 third quarter and first nine months increased 7% and 6%, respectively, compared with the 2009 third quarter and first nine months, primarily reflecting higher costs and expenses associated with increased marine transportation volumes and the 15% and 35%, respectively, increase in diesel fuel prices. Unfavorable winter and spring weather operating conditions during the 2010 first and second quarters and numerous lock repairs during the third quarter compared with more favorable conditions during the 2009 comparable periods also increased operating expenses.

Costs of sales and operating expenses for the 2010 third quarter and first nine months increased 9% and 8%, respectively, compared with the third quarter and first nine months of 2009, reflecting higher expenses associated with the increased demand and higher fuel costs as noted above, partially offset by the positive impact of cost savings initiatives.

The marine transportation segment operated an average of 217 towboats during the 2010 third quarter compared with 215 during the 2009 third quarter. During the 2010 first nine months, the segment operated an average of 221 towboats, compared with 222 towboats operated during the 2009 first nine months.

During the 2010 third quarter, the Company consumed 10.8 million gallons of diesel fuel compared to 11.0 million gallons consumed during the 2009 third quarter. For the 2010 first nine months, the Company consumed 32.4 million gallons of diesel fuel compared with 31.2 million during the 2009 first nine months. The average price per gallon of diesel fuel consumed during the 2010 third quarter was $2.17, an increase of 15% compared with $1.89 per gallon for the third quarter of 2009, and $2.20 per gallon for the 2010 first nine months, a 35% increase when compared with $1.63 per gallon for the 2009 first nine months. The lower gallons consumed during the 2010 third quarter as compared with the 2009 third quarter primarily reflected the decline in agricultural chemical and river refined products volumes as noted above. The higher gallons consumed during the 2010 first nine months reflected higher overall demand levels and more normal weather conditions during the 2010 first nine months that required additional horsepower, compared with the milder weather conditions during the 2009 first nine months.

KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES

Selling, general and administrative expenses for the 2010 third quarter and first nine months increased 9% and 2%, respectively, compared with the 2009 third quarter and first nine months, primarily the result of salary increases effective April 1, 2010 and higher incentive compensation accruals in the 2010 third quarter and first nine months, partially offset by the reduced number of administrative personnel, resulting from the 2009 and 2010 first quarter retirements and staff reductions, and a lower provision for doubtful accounts. The 2010 first quarter included a retirement and shore staff reduction charge of $2,724,000 compared to a charge of $2,527,000 in the 2009 first quarter.

Taxes, other than on income, for the 2010 third quarter and first nine months increased 2% and 13%, respectively, compared with the third quarter and first nine months of 2009, primarily the reflection of higher waterway user taxes from increased mileage associated with improved demand on taxable waterways and higher property taxes.

Depreciation and amortization for the 2010 third quarter decreased 4% compared with the 2009 third quarter and increased 1% for the 2010 first nine months compared with the 2009 first nine months. The 4% decrease and 1% increase reflected the net changes of asset lives on certain equipment with revised accelerated tank barge retirement schedules and increased capital expenditures, including new tank barges and towboats.

Marine Transportation Operating Income and Operating Margins

The marine transportation operating income for the 2010 third quarter and first nine months decreased 11% and 9%, respectively, compared with the 2009 third quarter and first nine months. The operating margin was 22.1% for the 2010 third quarter compared with 25.3% for the 2009 third quarter and 21.0% for the 2010 first nine months compared with 23.6% for the 2009 first nine months. Both the lower operating income and lower operating margin for both comparable periods were a reflection of lower term contract and spot contract rates negotiated throughout 2009 and the 2010 first half due to recessionary pressure and resulting industry-wide lower demand, higher fuel costs, and increased delay days during the 2010 third quarter and first nine months, partially offset by the cost reduction initiatives implemented during 2009 and the 2010 first quarter.

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 and reduction gears, and maintains facilities to rebuild component parts or entire medium-speed and high-speed diesel engines, and entire reduction gears. The Company services the marine, power generation and railroad markets.

Diesel Engine Services Revenues

The following table shows the markets serviced by the Company’s diesel engine services segment, the revenue distribution for the first nine months of 2010 and the customers for each market:


Markets Serviced	2010 Nine Months Revenue Distribution			Customers
Marine		68	%	Inland River Carriers – Dry and Liquid, Offshore Towing – Dry and Liquid, Offshore Oilfield Services – Drilling Rigs & Supply Boats, Harbor Towing, Dredging, Great Lake Ore Carriers
Power Generation		24	%	Standby Power Generation, Pumping Stations
Railroad		8	%	Passenger (Transit Systems), Class II, Shortline, Industrial

Diesel engine services revenues for the 2010 third quarter increased 9% compared with the 2009 third quarter and decreased 11% compared with the 2009 first nine months. During the 2009 third quarter, demand levels for all three markets declined significantly in response to the economic recession. The 2010 third quarter increase of 9% primarily reflected higher engine-generator set upgrades and higher engine and direct parts sales in the medium-speed power generation market. During the 2010 third quarter and first nine months, the segment continued to experience weak service levels and direct parts sales in both the medium-speed and high-speed marine markets, particularly the Gulf Coast oil services market where customers continue to defer major maintenance projects. During the 2010 second and third quarters the Gulf Coast oil services market was further weakened by the Gulf of Mexico deep water drilling moratorium and the uncertainty around new drilling regulations. In addition, the segment continued to experience pricing pressure in the high-speed marine market. The segment somewhat benefited from required repair work for customers involved in the Gulf Coast oil spill cleanup effort in the 2010 second and third quarters, and from modestly higher direct parts sales in the medium-speed railroad market in the 2010 first nine months. Both the 2010 and 2009 first quarters benefited from seasonal work for Midwest and Great Lakes medium-speed customers.

Diesel Engine Services Costs and Expenses

Costs and expenses for the 2010 third quarter increased 10% compared with the 2009 third quarter and decreased 10% for the 2010 first nine months compared with the 2009 first nine months. The 2009 first nine months included a $1,426,000 charge in the 2009 first quarter for early retirements and staff reductions applicable to the diesel engine services segment.

Cost of sales and operating expenses for the 2010 third quarter increased 13% compared with the 2009 third quarter, and decreased 9% for the first nine months of 2010 compared with the 2009 first nine months. The 2010 third quarter increase of 13% reflected the costs and expenses associated with the stronger power generation engine-generator set upgrades, engine sales and higher direct parts sales, partially offset by lower marine market service and direct parts sales activity noted above, and cost savings from the 2009 staff reductions. The 2010 first nine months decrease of 9% reflected the overall lower service and direct parts sales activity noted above. The 2009 first nine months expenses included $621,000 of the 2009 first quarter early retirements and staff reduction charge.

Selling, general and administrative expenses for the 2010 third quarter and first nine months decreased 2% and 14%, respectively, when compared with the 2009 third quarter and first nine months, reflecting the cost savings from the 2009 staff reductions. The 2009 first nine months expenses included $805,000 of the 2009 first quarter early retirements and staff reduction charge.

Diesel Engine Services Operating Income and Operating Margins

Operating income for the diesel engine services segment for the 2010 third quarter and first nine months decreased 3% and 21%, respectively, compared with the 2009 corresponding periods. The operating margin for the 2010 third quarter was 9.3% compared with 10.4% for the 2009 third quarter and 9.7% for the 2010 first nine months compared with 10.9% for the 2009 first nine months. The 2009 first nine months included a $1,426,000 first quarter early retirements and staff reductions charge. The 2010 third quarter and first nine months operating income reflected the continued weak medium-speed and high-speed Gulf Coast oil services and inland marine markets, and some downward pressure on pricing in the high-speed marine market, partially offset by cost reduction initiatives implemented during 2009. The 2010 third quarter and first nine months operating margin reflected the lower service and direct parts sales, some pricing pressure in the high-speed marine market and lower labor utilization, partially offset by the positive impact of the 2009 cost reduction initiatives. The 2009 first nine months operating income and operating margin was negatively impacted by the 2009 first quarter charge for early retirements and staff reductions noted above.

General Corporate Expenses

General corporate expenses for the 2010 third quarter were $3,175,000, a 1% increase compared with $3,129,000 for the third quarter of 2009. For the first nine months of 2010, general corporate expenses were $10,590,000, a 17% increase compared with $9,045,000 for the first nine months of 2009. The increase for the 2010 first nine months included $1,088,000 of the 2010 first quarter charge for retirements and staff reductions noted above and higher incentive compensation accruals.

Interest Expense

Interest expense for the 2010 third quarter and first nine months decreased 1% and 3%, respectively, compared with the third quarter and first nine months of 2009, primarily the result of lower average debt levels, partially offset by higher average interest rates. The average debt and average interest rate for the 2010 and 2009 third quarters, including the effect of interest rate swaps, were $200,186,000 and 5.5%, and $205,886,000 and 5.4%, respectively. For the first nine months of 2010 and 2009, the average debt and average interest rate, including the effect of interest rate swaps, were $200,209,000 and 5.4%, and $220,565,000 and 5.1%, respectively.

KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES

Current assets as of September 30, 2010 increased 30% compared with December 31, 2009, primarily reflecting a 53% increase in cash and cash equivalents. Trade accounts receivable increased 12%, primarily a reflection of higher 2010 third quarter marine transportation revenues when compared with the 2009 fourth quarter, partially associated with the pass through to customers of higher diesel fuel costs as fuel is escalated and de-escalated through revenue adjustment clauses in customers’ term contracts. Other accounts receivable increased 359%, predominately due to a federal income tax receivable as of September 30, 2010 of $25,169,000, the result of the recently enacted Small Business Jobs Act of 2010 that included a one-year extension of bonus tax depreciation on qualified property. This extension was granted after the Company’s estimated tax payment was made on September 15, 2010, based on the assumption that bonus tax depreciation would not be extended and, as a result, the Company overpaid its 2010 estimated federal income taxes. Finished goods inventory decreased 6% due to the continued reduction of diesel engine services inventory levels associated with the weak business levels.

Property and equipment, net of accumulated depreciation, at September 30, 2010 increased 3% compared with December 31, 2009. The increase reflected $108,036,000 of capital expenditures for the 2010 first nine months, more fully described under Capital Expenditures below, less $68,727,000 of depreciation expense for the first nine months of 2010 and $6,672,000 of property disposals during the 2010 first nine months.

Current liabilities as of September 30, 2010 increased 11% compared with December 31, 2009. Accounts payable increased 19%, a reflection of the higher business activity levels during the 2010 first nine months in the marine transportation segment and higher shipyard accruals. Accrued liabilities increased 5%, primarily from higher property tax accruals, marine insurance claims and deferred revenues, partially offset by payments during the 2010 first nine months of employee incentive compensation accrued during 2009 and payment of severance accrued in the 2009 fourth quarter.

Long-term debt, less current portion, as of September 30, 2010 was in line with December 31, 2009 as the Company had no outstanding balance under its $250,000,000 revolving credit facility during the first nine months of 2010.

Deferred income taxes as of September 30, 2010 increased 12% compared with December 31, 2009. The increase was primarily due to the 2010 first nine months deferred tax provision of $28,025,000, which included bonus tax deprecation on qualifying expenditures due to the recently enacted one-year extension of bonus tax depreciation as noted above.

Other long-term liabilities as of September 30, 2010 increased 33% compared with December 31, 2009, primarily reflecting increased pension plan accruals, and the recording of a $4,566,000 increased liability in the fair value of derivative instruments, more fully described under Fair Value of Derivative Instruments below.

KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES

Equity as of September 30, 2010 increased 7% compared with December 31, 2009. The increase was the result of $84,629,000 of net earnings attributable to Kirby for the 2010 first nine months, a decrease of $5,237,000 in accumulated other comprehensive income and an increase in treasury stock of $14,400,000. The decrease in accumulated other comprehensive income primarily resulted from the net change in fair value of derivative instruments, net of taxes, more fully described under Fair Value of Derivative Instruments below and the increase in unrecognized losses related to the Company’s defined benefit plans. The increase in treasury stock was attributable to purchases during the 2010 second and third quarters of $20,584,000 of Company common stock, partially offset by the exercise of stock options and the issuance of restricted stock during the 2010 first nine months.

Long-Term Financing

The Company has a $250,000,000 unsecured revolving credit facility (“Revolving Credit Facility”) with a syndicate of banks, with JPMorgan Chase Bank as the agent bank, with a maturity date of June 14, 2011. 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 elected to participate in the increased commitment. The unsecured Revolving Credit Facility has a variable interest rate based on LIBOR that varies with the Company’s senior debt rating and the level of debt outstanding. As of September 30, 2010, the Company was in compliance with all Revolving Credit Facility covenants and had no borrowings outstanding under the Revolving Credit Facility during any portion of the quarter. 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 $11,000 as of September 30, 2010.

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 September 30, 2010, $200,000,000 was outstanding under the Senior Notes and the average interest rate for the 2010 third quarter and first nine months was 1.0% and 0.9%, respectively. The Company was in compliance with all Senior Notes covenants at September 30, 2010.

The Company has a $5,000,000 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, 2011. 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 September 30, 2010. Outstanding letters of credit under the Credit Line were $4,030,000 as of September 30, 2010.

Interest Rate Risk Management

KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES

From time to time, the Company hedges its exposure to fluctuations in short-term interest rates under its variable rate bank credit facility and floating rate senior notes by entering into interest rate collar and swap agreements. The interest rate collar and swap agreements are designated as cash flow hedges, therefore, the changes in fair value, to the extent the collar and swap agreements are effective, are recognized in OCI until the hedged interest expense is recognized in earnings. The 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 LIBOR to quarterly fixed rate payments. As of September 30, 2010, 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):


Notional Amount	Effective date	Termination date	Fixed pay rate	Receive rate
$ 100,000	March 2006	February 2013	5.45%	Three-month LIBOR
$ 50,000	November 2008	February 2013	3.50%	Three-month LIBOR
$ 50,000	May 2009	February 2013	3.795%	Three-month LIBOR

Capital Expenditures

Capital expenditures for the 2010 first nine months were $108,036,000, of which $60,330,000 was for construction of new tank barges and towboats, and $47,706,000 was primarily for upgrading of the existing marine transportation fleet. Capital expenditures for the 2009 first nine months were $162,972,000, of which $121,742,000 was for construction of new tank barges and towboats, and $41,230,000 was primarily for upgrading of the existing marine transportation fleet. Financing of the construction of the new tank barges and towboats was through operating cash flows and available credit under the Company’s Revolving Credit Facility.

During the 2010 first nine months, the Company took delivery of 48 new tank barges and five new chartered tank barges with a total capacity of 638,000 barrels, and three new 1800 horsepower towboats. During the 2010 fourth quarter, the Company anticipates the delivery of 10 new tank barges with a total capacity of 140,000 barrels. The Company projects capital expenditures for 2010 will be in the $135,000,000 to $145,000,000 range, including approximately $70,000,000 for new tank barge and towboat construction, taking advantage of current attractive tank barge construction prices, and prepayments on 2011 new tank barge construction. The Company’s current plans are not to expand the fleet and to use these new tank barges to replace older equipment removed from service. During the 2010 first nine months, the Company retired 66 tank barges, reducing its capacity by 1,014,000 barrels. Based on current commitments, steel prices and projected delivery schedules, the Company’s 2011 new construction capital expenditures will consist of 31 new tank barges with a total capacity of 868,000 barrels in the $50,000,000 to $60,000,000 range.

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

Treasury Stock Purchases

During the 2010 third quarter, the Company purchased 497,000 shares of its common stock for $18,887,000, for an average price per share of $38.01. From June through October 2010, the Company purchased 618,000 shares of its common stock for $23,793,000, for an average price per share of $38.47. The common stock was purchased through a combination of discretionary purchases and purchases pursuant to a stock trading plan entered into with a brokerage firm pursuant to Rule 10b5-1 under the Securities and Exchange Act of 1934. The Company’s Board of Directors on July 27, 2010 authorized the repurchase of an additional 2,000,000 shares of its common stock. As of November 3, 2010, the Company had 2,086,000 shares available under its existing repurchase authorizations. Historically, treasury stock purchases have been financed through operating cash flows and borrowing 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 $169,837,000 during the nine months ended September 30, 2010 compared with $237,101,000 generated during the nine months ended September 30, 2009. The 2010 first nine months experienced a net $22,874,000 decrease in cash flows from changes in operating assets and liabilities, primarily due to a federal income tax receivable as of September 30, 2010 of $25,169,000, the result of the recently enacted Small Business Jobs Act of 2010 that included a one-year extension of bonus tax depreciation on qualified property. This extension was granted after the Company’s estimated tax payment was made on September 15, 2010, based on the assumption that bonus tax depreciation would not be extended and, as a result, the Company overpaid its 2010 estimated federal income taxes. The 2009 first nine months experienced a net decrease in cash flows from changes in operating assets and liabilities of $31,964,000, primarily due to a decrease in receivables in the 2009 first nine months as a result of decreased revenues due to weaker business activity levels.

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 November 3, 2010, $249,989,000 under its Revolving Credit Facility and $861,000 available under its Credit Line and cash and cash equivalents of $159,201,000.

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.

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

KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES

The Revolving Credit Facility’s commitment is in the amount of $250,000,000 and expires June 14, 2011. As of September 30, 2010, the Company had $249,989,000 available under its Revolving Credit Facility. Future extension of the Revolving Credit Facility may contain terms that are less favorable than those of the current Revolving Credit Facility should current credit market volatility be prolonged. The Revolving Credit Facility also allows for an increase in the commitments from the banks from the current $250,000,000 level up to a maximum of $325,000,000, subject to the consent of each bank that elects to participate in the increased commitment. Based on current economic conditions and credit market volatility, there is no guarantee that the participating banks would elect to increase the commitment, and if they did, the terms may be less favorable than the current Revolving Credit Facility. The Senior Notes do not mature until 2013 and require no prepayments. While the Company has no current plans to access the bond market or private placement market, should the Company decide to do so in the near term, the terms, size and cost of a new debt issue could be less favorable.

Current market conditions also elevate the concern over counterparty risks related to the Company’s interest rate swap agreements used to hedge the Company’s exposure to fluctuating interest rates and the Company’s forward contracts used to hedge the Company’s exposure to fluctuating foreign currency rates. The counterparties to these contracts are large multinational banks. The Company may not realize the benefit of some of its hedges should one of these financial counterparties not perform.

There are numerous factors that may negatively impact the Company’s cash flow in 2010. For a list of significant risks and uncertainties that could impact cash flows, see Note 12, Contingencies and Commitments, and Item 1A – Risk Factors, in the Company’s annual report on Form 10-K for the year ended December 31, 2009. 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 5, Long-Term Debt, in the Company’s annual report on Form 10-K for the year ended December 31, 2009.

All marine transportation term contracts contain fuel escalation clauses. 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 and 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.

Item 3.

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 have no impact on the 2010 interest expense based on balances outstanding at December 31, 2009 as the Company’s outstanding debt is approximately 100% hedged by interest rate swaps, and would change the fair value of the Company’s debt by less than 1%.

Interest Rate Risk Management

From time to time, the Company hedges its exposure to fluctuations in short-term interest rates under its variable rate bank credit facility and floating rate senior notes by entering into interest rate collar and swap agreements. The interest rate collar and swap agreements are designated as cash flow hedges, therefore, the changes in fair value, to the extent the collar and swap agreements are effective, are recognized in OCI until the hedged interest expense is recognized in earnings. The 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 LIBOR to quarterly fixed rate payments. As of September 30, 2010, 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):


Notional Amount	Effective date	Termination date	Fixed pay rate	Receive rate
$ 100,000	March 2006	February 2013	5.45%	Three-month LIBOR
$ 50,000	November 2008	February 2013	3.50%	Three-month LIBOR

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 September 30, 2010.
