NOTES TO CONDENSED FINANCIAL STATEMENTS
(Unaudited)

(1)BASIS FOR PREPARATION OF THE CONDENSED FINANCIAL STATEMENTS

The condensed financial statements included herein have been prepared by Kirby Corporation (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, 2015.2016.

(2)ACCOUNTING STANDARDS ADOPTIONS

In August 2016,March 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-07, “Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” (“ASU 2017-07”) which requires employers to include only the service cost component of net periodic pension cost and net periodic postretirement benefit cost in operating expenses. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations.  The standard allows only the service cost component to be eligible for capitalization when applicable.  ASU 2017-07 is effective for annual and interim periods beginning after December 15, 2017 with early adoption permitted.  This standard shall be applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost in the income statement and prospectively for the capitalization of the service cost benefit in assets.  The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04, “Intangibles – Goodwill and Other (Topic 350):  Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”) which simplifies the subsequent measurement of goodwill by eliminating Step 2 in the goodwill impairment test that required an entity to perform procedures to determine the fair value of its assets and liabilities at the testing date.  An entity instead will perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying value and record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary.  ASU 2017-04 will be applied prospectively and is effective for annual and interim goodwill impairment tests conducted in fiscal years beginning after December 15, 2019.  Early adoption is permitted for interim or annual goodwill impairment testing dates after January 1, 2017.  The Company is currently evaluating the impact, if any, that the adoption of this standard will have on its consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments” (“ASU 2016-15”) to create consistency in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. ASU 2016-15 is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, “Improvements“Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”) which simplifies several aspects of the accounting for share-based payment transactions, including income tax consequences, forfeitures, minimum statutory tax withholding requirements, classification as either equity or liabilities, and classification on the statement of cash flows. The Company adopted the provisions of ASU 2016-09 is effective for annualon January 1, 2017.  ASU 2016-09 requires all excess tax benefits and interim periods beginning after December 15, 2016. Early adoption is permitted with any adjustments reflectedtax deficiencies be recognized as income tax expense or benefit in the income statement, thus eliminating additional paid-in capital pools.  The Company recognized a cumulative effect adjustment of $8,486,000 to retained earnings on a modified retrospective basis as of January 1, 2017 and will apply the beginningnew standard guidance prospectively to all excess tax benefits and tax deficiencies resulting from settlements after January 1, 2017.  The standard also requires a policy election to either estimate the number of the fiscal year of adoption.awards that are expected to vest or account for forfeitures when they occur.  The Company is currently evaluatingwill elect to account for forfeitures when they occur.  Also, the impactstandard requires that excess tax benefits should be classified along with other income tax cash flows as an operating activity on the statement of adoptingcash flows, which differs from the Company’s historical classification of excess tax benefits as cash inflows from financing activities.  The Company elected to apply this guidance.provision using the prospective transition method.  Additionally, the standard requires cash paid by an employer when directly withholding shares for tax withholding purposes to be classified in the statement of cash flows as a financing activity, which differs from the Company’s previous method of classification of such cash payments as an operating activity.  The Company applied this provision retrospectively and, for the three months ended March 31, 2016, reclassified $1,749,000, which increased net cash provided by operating activities and net cash used in financing activities.

6

In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”) to increase transparency and comparability among organizations by requiring recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements. ASU 2016-02 is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted. A modified retrospective approach is required. The Company is currently evaluatinghas formed a project team to evaluate the impact that the adoption of this standard will have on its consolidated financial statements and disclosures. The project team has completed training on the new standard and has started lease review and documentation, but the Company has not yet determined the effect of ASU 2016-02 on its ongoing financial reporting.

In November 2015, the FASB issued ASU 2015-17, “Balance Sheet Classification of Deferred Taxes” (“ASU 2015-17”) which requires that deferred tax liabilities and assets be classified as noncurrent on the balance sheet. The current requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and presented as a single amount is not affected by this guidance. ASU 2015-17 is effective for annual and interim periods beginning after December 15, 2016 but early application is permitted and theThe guidance may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. The Company does not anticipateadopted the provisions of ASU 2015-17 on January 1, 2017 on a material impact on itsretrospective basis.  The December 31, 2016 current deferred tax assets of $13,604,000 have been reclassified in the consolidated financial statements at the time of adoption of this new standard.balance sheet from current deferred income taxes asset to noncurrent deferred income taxes liability.

In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory” (“ASU 2015-11”) which applies to inventory that is measured using first-in, first-out (“FIFO”) or average cost. Under the guidance, an entity should measure inventory that is within the scope of this update at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. ASU 2015-11 is effective for annual and interim periods beginning after December 15, 2016, and should be applied prospectively with early adoption permitted at the beginning of an interim period or annual reporting period. The Company is currently evaluating the impact of adopting this guidance.
6

In April 2015, the FASB issued ASU 2015-03, “Simplifying the Presentation of Debt Issuance Costs” (“ASU 2015-03”). ASU 2015-03 requires debt issuance costs to be presented in the balance sheet as a direct deduction from the associated debt liability. Effective January 1, 2016, the Company adopted the provisions of ASU 2015-032015-11 on January 1, 2017 and, prior period amounts have been reclassified to conform to the current period presentation. Thebased on a lower of cost and net realizable value inventory analysis as of December 31, 2015 net debt issuance costs2016, no adjustments to inventory value were required.  The analysis reflected the inventory values are proper within the guidance of $3,985,000 have been reclassified in the consolidated balance sheet from other assets to long-term debt, less current portion.ASU 2015-11.

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”). ASU 2014-09 requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in United States Generally Accepted Accounting Principles when it becomes effective. In July 2015, the FASB voted to delay the effective date of ASU 2014-09 by one year, making it effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, with early adoption permitted as of the original effective date. ASU 2014-09 permits the use of either the retrospective, modified retrospective or prospective with a cumulative effect transition method.catch-up approach.

(11)(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.
13

On April 12, 2017, the Company amended its pension plan to cease all benefit accruals for periods after May 31, 2017 for certain participants.  Participants who will be grandfathered and not be impacted are those, as of the close of business on May 31, 2017, who either (a) have completed 15 years of pension service or (b) have attained age 50 and completed 10 years of pension service.    Participants who are non-grandfathered will be eligible to receive discretionary 401(k) plan contributions.   The Company does not expect any one-time charges related to this amendment but does expect the plan amendment to reduce the pension plan’s projected benefit obligation.  The Company is in the process of having its actuary remeasure its pension plan obligations.

The Company’s pension plan funding strategy has historically beenis to contribute an amountmake annual contributions in amounts equal to theor greater of the minimum required contribution under ERISA or the amountthan amounts necessary to fully fund the plan on an accumulatedmeet minimum government funding requirements.  The plan’s benefit obligation (“ABO”) basis at the end of the fiscal year. The ABO isobligations are 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 expectsdoes not expect to make a contribution of up to $25,000,000 to its pension plan prior to December 31, 2016 to fund its 2016 pension plan obligations. As of September 30, 2016, no 2016 year contributions have been made.during 2017.

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 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.

On October 13, 2016, the tug Nathan E. Stewart and barge DBL 55, an articulated tank barge and tugboat unit (“ATB”), ran aground at the entrance to Seaforth Channel on Atholone Island, British Columbia. The grounding resulted in a breach of a portion of the Nathan E. Stewart’s fuel tanks causing a discharge of diesel fuel into the water.  The Company has undertaken its responsibilities to salvage and cleanup. The United States Coast Guard (“USCG”) and the National Transportation Safety Board (“NTSB”) designated the Company as a party of interest in their investigation as to the cause of the incident. The Canadian authorities including Transport Canada and the Canadian Transportation Safety Board are also investigating the cause of the incident. The Company is subject to claims from third parties as well as the provincial and federal government as a result of the incident. The Company has various insurance policies covering liabilities including pollution, property, marine and general liability. The Companyliability and believes that it has satisfactory insurance coverage for the cost of cleanup and salvage operations as well as other potential liabilities arising from the incident.

On March 22, 2014, two tank barges and a towboat (the M/V Miss Susan), owned by Kirby Inland Marine, LP, a wholly owned subsidiary of the Company, were involved in a collision with the M/S Summer Wind on the Houston Ship Channel near Texas City, Texas. The lead tank barge was damaged in the collision resulting in a discharge of intermediate fuel oil from one of its cargo tanks. The USCG and the NTSB named the Company and the Captain of the M/V Miss Susan, as well as the owner and the pilot of the M/S Summer Wind, as parties of interest in their investigation as to the cause of the incident. Sea Galaxy Ltd is the owner of the M/S Summer Wind. The Company is participating in the natural resource damage assessment and restoration process with federal and state government natural resource trustees.

The Company and the owner of the M/S Summer Wind filed actions in the U.S. District Court for the Southern District of Texas seeking exoneration from or limitation of liability relating to the foregoing incident as provided for in the federal rules of procedure for maritime claims. The two actions were consolidated for procedural purposes since they both arise out of the same occurrence. Multiple parties filed claims in limitation seeking various damages under the Oil Pollution Act of 1990 (“OPA”), including claims for business interruption, loss of profit and loss of use of natural resources (OPA claimants). On November 2, 2016, the Company, the M/S Summer Wind and its owners and the OPA claimants entered into a settlement agreement pursuant to which the parties have resolved their respective claims against one another. The Company has adequate insurance for its sharedismissal of the settlement payment.OPA claims was entered by the Court on November 14, 2016.  On March 22, 2017, the deadline for claimants to file claims under OPA passed as the three year statute of limitations expired.

Overview

The Company is the nation’s largest domestic tank barge operator, transporting bulk liquid products throughout the Mississippi River System, on the Gulf Intracoastal Waterway, coastwise along all three United States coasts and in Alaska and Hawaii. The Company transports petrochemicals, black oil, refined petroleum products and agricultural chemicals by tank barge. As of September 30, 2016,March 31, 2017, the Company operated a fleet of 881864 inland tank barges with 17.917.6 million barrels of capacity, and operated an average of 227235 inland towboats during the 2016 third2017 first quarter. The Company’s coastal fleet consisted of 68 tank barges with 6.06.1 million barrels of capacity and 8071 coastal tugboats. The Company also owns and operates sixfive offshore dry-bulk bargecargo barges and five offshore tugboats and one docking tugboat units transporting dry-bulk commodities in United States coastal trade. Through its diesel engine services segment, the Company provides after-market services for medium-speed and high-speed diesel engines, reduction gears and ancillary products for marine and power generation applications, distributes and services high-speed diesel engines, transmissions and pumps, and manufactures and remanufactures oilfield service equipment, including pressure pumping units, for the land-based oilfield service and oil and gas operator and producer markets.

For the 2016 third2017 first quarter, net earnings attributable to Kirby were $32,010,000,$27,483,000, or $0.59$0.51 per share, on revenues of $434,708,000,$491,705,000, compared with 2015 third2016 first quarter net earnings attributable to Kirby of $56,843,000,$38,099,000, or $1.04$0.71 per share, on revenues of $532,565,000. For the 2016 first nine months, net earnings attributable to Kirby were $109,051,000, or $2.02 per share, on revenues of $1,335,023,000, compared with 2015 first nine months net earnings attributable to Kirby of $175,996,000, or $3.17 per share, on revenues of $1,663,394,000.$458,733,000. The 2016 first quarter and first nine months results included $5,605,000 before taxes, or $.06 per share, of severance charges. The severance charges were a result of a reduction in force across the marine transportation and diesel engine services businesses and corporate staff in order to reduce costs in light of challenging market conditions. The 2015 first quarter, third quarter and first nine months included $1,225,000, $702,000 and $1,927,000, respectively, of severance charges which were mainly reflected in the diesel engine services results. Also, the 2015 first quarter and first nine months results included a gain of $1,621,000 before taxes, or $.02 per share, on the sale of the assets of a small product line in the diesel engine services segment.

Marine Transportation

For the 2016 third2017 first quarter, and first nine months, the Company’s marine transportation segment generated 83% and 84%, respectively,70% of the Company’s revenues.revenue was generated by its marine transportation segment. The segment’s customers include many of the major petrochemical and refining companies that operate in the United States. Products transported include intermediate materials used to produce many of the end products used widely by businesses and consumers — plastics, fiber, paints, detergents, oil additives and paper, among others, as well as residual fuel oil, ship bunkers, asphalt, gasoline, diesel fuel, heating oil, crude oil, natural gas condensate and agricultural chemicals. Consequently, the Company’s marine transportation business generally mirrorsis directly affected by the volumes produced by the Company’s petroleum, petrochemical and refining customer base.

The Company’s marine transportation segment’s revenues for the 2016 third2017 first quarter and first nine months decreased 14% and 12%, respectively,9% when compared with the 2015 third2016 first quarter and first nine months. The decreases wererevenues, primarily due to lower inland marine transportation term and spot contract pricing, lower inland andcoastal marine transportation spot contract pricing, lower coastal equipment utilization a decline in the average cost of marine diesel fuel which is largely passed through to the customer, and an increase in the number of coastal vessels operating in the spot market which led to increased idle time and decreased revenues, partially offset by the addition of the SeacorSEACOR Holdings Inc. (“Seacor”) tank barges acquired in April 2016. The segment’s operating income for the 2016 third2017 first quarter and first nine months decreased 41% and 31%, respectively,49% compared with the 2015 third quarter and2016 first nine months.quarter. The decreases weredecrease was primarily due to lower inland and coastal equipment utilization, lower inland term and spot contract pricing, lower coastal spot contract pricing, lower coastal equipment utilization, and more coastal equipment operating in the spot market which adds increased idle time and voyage costs, for coastal vessels and higher depreciation expense, partially offset by savings from a reduction in force earlier in the yearcoastal market from the release of chartered tugboats, idling owned barges and during 2015,tugboats and reducing headcount accordingly and by a reduction in the average number of inland towboats operated.  The 2016 first nine monthsquarter marine transportation results also included $3,792,000 of severance charges in the 2016 first quarter.charges. For the 2017 and 2016 and 2015 thirdfirst quarters, the inland tank barge fleet contributed 66%71% and 68%67%, respectively, and the coastal fleet contributed 34%29% and 32%, respectively, of marine transportation revenues.  For the 2016 and 2015 first nine months, the inland tank barge fleet contributed 67% and 68%, respectively, and the coastal fleet contributed 33% and 32%, respectively, of marine transportation revenues.

Outlook

Reduced crude oil volumes to be moved by tank barge due to additional pipelines, coupled with the large number of tank barges built during the last several years, many of which were for the movement of crude oil and natural gas condensate, hashave resulted in excess industry-wide tank barge capacity and lower equipment utilization for both the inland and coastal marine transportation markets. This extra capacity has placed inland and coastal tank barge rates under some pressure. The Company’s inland term contract rates that renewed in the 2016 third quarter and first nine months decreased in the 5% to 9% average range compared with term contract rates renewed in the 2015 third quarter and first nine months. Spot contract rates, which include the cost of fuel, were relatively flat in the 2016 first quarter when compared with the 2015 fourth quarter and were at or below term contract rates for the 2016 second and third quarters. As a result, the Company remains cautious with regard to 2016 fourth quarter pricing expectationsinland market for the inland marine transportation marketsremainder of 2017 will be impacted by the pricing declines experienced throughout 2016 and expects continued modest pricing pressurethe 2017 first quarter. However, with anticipated utilization in the low-to-mid 80% range. Futuremid-80% to low 90% levels for 2017, the industry could achieve a supply and demand balance during 2017, leading to modestly improving pricing in the second half of the year. In addition, future inland tank barge demand for petrochemical and refined petroleum products volumes from increased production from current facilities, plant expansions or the reopeningopening of idlednew facilities could offset possible further declines in crude oil and natural gas condensateshould benefit the inland marine transportation movements.markets.

In the coastal marine transportation market, a decline in crude oil and natural gas condensate transportation volumes has increased available capacity and has resulted in some reluctance among certain customers to extend term contracts, which has led to an increase in the number of coastal vessels operating in the spot market. In addition, the Company and the industry have added new coastal tank barge capacity during 2015 and the 2016, first nine months, with additional new capacity coming on-line in 2017 and 2018. While much of this new capacity is replacement capacity for older vessels anticipated to be retired, the Company maintains a cautious outlook as the industry absorbs the new capacity. While the Company does expect the supply of tank barges and capacity in the coastal industry fleet to eventually balance with demand, the Company does not anticipate that balance occurring in 2017 without an improvement in demand.  As a result, in the 2017 first quarter, the Company released chartered tugboats, idled owned barges and tugboats and reduced headcount accordingly.  For the 2016 fourth quarter,remainder of 2017, the Company expects tank barge utilization for the coastal markets to remain in the low-to-mid 80% range.range from mid-70% to mid-80%.

As of September 30, 2016,March 31, 2017, the Company estimated there were approximately 3,9003,850 inland tank barges in the industry fleet, of which approximately 600500 were over 30 years old and approximately 250 of those over 40 years old. Given the age profile of the industry inland tank barge fleet and current market conditions, the expectation is that many older tank barges will be removed from service during 2016.2017.  The Company estimates that approximately 10040 tank barges were ordered during 2015 and 2016 for delivery throughout 2016,2017, five of which five wereare for the Company, significantly less than the 260 new inlandand many older tank barges, placed in service during 2015,including an expected 36 of which were forby the Company.Company, will be retired, dependent on 2017 market conditions. Historically, 75 to 150 older inland tank barges are retired from service each year industry-wide, with the extent of the retirements dependent on petrochemical and refinery production levels, and crude oil and natural gas condensate movements, both of which can have a direct effect on industry-wide tank barge utilization, as well as term and spot contract rates.

As of September 30, 2016,March 31, 2017, the Company estimated there were approximately 290295 tank barges operating in the 195,000 barrel or less coastal industry fleet, the sector of the market in which the Company operates, and approximately 35 of those were over 30 years old. In 2014 and 2015, theThe Company placed orders for the constructionexpects to take delivery of two 185,000 barrel coastal ATBs, one of which was placed in service in late 2015 and the second in June 2016, twoa new 155,000 barrel coastal ATBs, one scheduled to be placed in service in the 2016 fourth quarter and oneATB in the 2017 first half, one 35,000 barrel coastal petrochemical tank barge scheduled to be placed in service in early 2017 and two 4900 horsepower coastal tugboats.third quarter. The Company is also aware of 1911 announced coastal tank barge and tugboat units in the 195,000 barrel or less category under construction by competitors of which eight were delivered in the first nine months of 2016 and the remaining 11 are for delivery in 2017 and 2018.

In the land-based diesel engine services segment,market, the Company is experiencing a healthy rebound in service demand, particularly with pressure pumping unit remanufacturing. The United States land rig count has improved from the current crudelows of 2016, oil environmentprices have recently traded at a consistent level in the $50 per barrel range, and corresponding announced capital spending reductions by oilfield service companiesintensity in the well completion business has increased. The condition of the industry’s pressure pumping fleet is poor. Based on these positive conditions, the Company anticipates that for remainder of 2017 the demand for pressure pumping unit remanufacturing will remain strong and oil and gas operators and producers, inboundthat a small number of orders during the 2016 first nine months for the manufacturing ofnew pressure pumping units and otherancillary oilfield service support equipment have essentially stopped. However, the 2016 third quarter saw an increase in activity for the remanufacturing and servicing of pressure pumping units. The distribution portion of the land-based market, including engine, transmission and parts sales and service, remains at weaker levels. The Company took aggressive measures in 2015 and the 2016 first quarter to reduce costs, including reducing the staffing level in the land-based manufacturing area. The Company anticipates its land-based market to remain challenging for the 2016 fourth quarter as a more meaningful recovery in the land-based market is not likely until 2017, when customer inventories for parts, transmissions and engines are depleted and oilfield service activity accelerates, which may necessitate new orders for products, parts and service.will be received.

For the marine diesel engine services market, the Company anticipates continued weakness in the Gulf of Mexico oilfield services market.  Formarket throughout the remainder of 2017, with the other marine markets to remain relatively consistent with 2016 and the 2017 first quarter.  The power generation market should remain stable, benefiting from engine-generator set upgrades and other marine markets in the 2016 fourth quarter, the Company anticipates a normal fourth quarter seasonal decline.parts sales for both domestic and international customers.

Marine transportation revenues for the 2016 third2017 first quarter and first nine months decreased 14% and 12%, respectively,9% when compared with the 2015 third2016 first quarter, and first nine months, primarily due to lower inland marine transportation term and spot contract pricing, lower inland andcoastal marine transportation spot contract pricing, lower coastal equipment utilization a decline in the average cost of marine diesel fuel for the 2016 third quarter and first nine months of 17% and 30%, respectively, which is largely passed through to the customer, and an increase in the number of coastal vessels operating in the spot market which led to increased idle time and decreased revenues, partially offset by the addition of the Seacor tank barges acquired in April 2016. Results were also impacted by customer requested acceleration of regulatory shipyards on two large units into the 2017 first quarter. For the 2017 and 2016 and 2015 thirdfirst quarters, the inland tank barge fleet contributed 66%71% and 68%67%, respectively, and the coastal fleet contributed 34%29% and 32%33%, respectively, of marine transportation revenues. ForTank barge utilization levels of the 2016 and 2015 first nine months, the inland tank barge fleet contributed 67% and 68%, respectively, and the coastal fleet contributed 33% and 32%, respectively, of marine transportation revenues. The Company’s inland marine transportation fleet tank barge utilization levels declinedmarkets were in the 2016 third quarter to the low-to-mid 80% range compared to the high 80% to low 90% range forduring the 2017 first quarter compared to the low 80% to high 80% range during the 2016 secondfourth quarter and the 90% to 95% range for the 2016 first quarter and the 2015 third quarter and first nine months.  The decline inquarter.  Coastal tank barge utilization from the 2016 first quarter to 2016 second quarter was largely attributable to a shortened spring season for agricultural chemical products and soft demand for transportation of refined petroleum products, which was largely related to high inventory levels.  The decline in utilization from the 2016 second quarterlevels declined to the 2016 third quarter was mainly duemid-70% to high refined petroleum product inventory levels, as well as overall softer utilization levels that are common in mid-summer as operating conditions improve.  The utilization levels for the coastal marine transportation markets declined slightly to the low-to-midlow 80% range during the 2016 third2017 first quarter compared to the midlow 80% level duringin the 2016 secondfourth quarter and the high 80% to low 90% range in the 2016 first quarter and compared to utilization levels of 90% to 95%quarter.  Utilization in the 2015 third quarter and first nine months.coastal marine fleet continued to be impacted by the oversupply of tank barges in the coastal industry.

The petrochemical market, the Company’s largest market, contributed 49%55% of marine transportation revenues for the 2016 third2017 first quarter, and first nine months, reflecting continued stable volumes from Gulf Coast petrochemical plants for both domestic consumption and to terminals for export destinations, aside frompartially offset by the negative impact of plant maintenance turnarounds.  Also, demand for movements of certain upriver petrochemicals was strong in the 2016 third quarter.  Low priced domestic natural gas, a basic feedstock for the United States petrochemical industry, provides the industry with a competitive advantage relative to naphtha-based foreign petrochemical producers.

The black oil market, which contributed 25%24% of marine transportation revenues for the 2016 third2017 first quarter, and first nine months, respectively, reflected lowerhigher fleet utilization in the inland market compared to demand in the 2016 fourth quarter due to commodity price volatility. Duringrefinery turnarounds during the 2016 third quarter, the2017 first quarter. The Company continued to transport crude oil and natural gas condensate produced from the Eagle Ford and Permian Basin shale formations in Texas both along the Gulf Intracoastal Waterway with inland vessels and in the Gulf of Mexico with coastal equipment, and continued to transport Utica natural gas condensate downriver from the Mid-Atlantic to the Gulf Coast, however at significantly reduced levels compared with the 2015 third quarter and2016 first nine months.quarter.

The refined petroleum products market, which contributed 23%17% of marine transportation revenues for the 2016 third2017 first quarter, and first nine months, respectively, reflected increasedstable volumes in the inland market, as a result of the Seacor acquisition in April 2016, partially offset by soft demand in the coastal market, primarily a result of weak distillate and gasolineheating oil demand in the 2017 first quarter due to the unseasonably warm weather in the Northeast.

The agricultural chemicalschemical market, which contributed 3%4% of marine transportation revenues for the 2016 third2017 first quarter, and first nine months, saw typical seasonal demand for transportation of both domestically produced and imported products during the first and third quarters and a decline in demand in the second quarter, primarily due to a shortened spring season.quarter.

For the thirdfirst quarter of 2016,2017, the inland operations incurred 9292,267 delay days, 35% less1% more than the 1,431 delay days that occurred during the 2015 third quarter and 54% less than the 2,0352,236 delay days that occurred during the 2016 second quarter. For the first nine months of 2016, 5,200 delay days occurred, 12% lessquarter and 9% more than the 5,8852,078 delay days that occurred during the 2015 first nine months.2016 fourth quarter. Delay days measure the lost time incurred by a tow (towboat and one or more tank barges) during transit when the tow is stopped due to weather, lock conditions or other navigational factors. DuringOperating conditions during the 2016 third2017 first quarter operating conditions were seasonally normal although there was significant flooding in Louisiana that caused some disruptions inwith periodic high wind and heavy fog along the Gulf Intracoastal Waterway for a short period.Coast.

During the 2017 and 2016 first quarters, approximately 75% and 2015 third quarters and first nine months, approximately 80%, respectively, of inland marine transportationtransportation’s inland revenues were under term contracts and 25% and 20%, respectively, were spot contract revenues. Inland time charters duringrepresented 48% of the 2016 third quarter and first nine months represented 52% and 53%, respectively, of theinland revenues under term contracts during the 2017 first quarter compared with 55% and 56% induring the 2015 third quarter and2016 first nine months, respectively.quarter.

During the 2017 and 2016 third quarter and first nine months,quarters, approximately 80% of the coastal revenues were under term contracts and 20% were spot contract revenues.  For the 2015 third quarter and first nine months, approximately 80% and 85%, respectively, of marine transportation’s coastal revenues were under term contracts and approximately 20% and 15%, respectively, were under spot contracts.  The 2016 first nine months decrease in term contract revenues reflected the continued trend of non-renewal of certain term contracts which put increased equipment in the spot contract market, leading to increased idle time. However, the coastal revenues reflected the new 185,000 barrel ATB placed in service in the 2015 fourth quarter under a long-term contract.  The second new 185,000 barrel ATB was placed in service in June 2016, also under a long-term contract.  Coastal time charters represented approximately 90%85% of thecoastal revenues under term contracts during the 2017 first quarter compared with 90% during the 2016 and 2015 third quarters and first nine months.quarter.

Rates on inland term contracts renewed in the 2016 third2017 first quarter and first nine months decreased in the 5%4% to 9%6% average range compared with term contracts renewed in the 2015 thirdfirst quarter and first nine months.of 2016. Spot contract rates, which include the cost of fuel, were relatively flat in the 2016 first quarter when compared with the 20152016 fourth quarter, and at orbut below term contract pricing during the 2016 second and third quarters.rates. Effective January 1, 2016,2017, annual escalators for labor and the producer price index on a number of inland multi-year contracts resulted in rate increases on those contracts of approximately 1.5%0.6%, excluding fuel.

Rates on coastal term contracts renewed in the 2016 third2017 first quarter and first nine months were essentially flat when compared with term contracts renewed in the 2015 third2016 first quarter, although most contracts failed to renew and first nine months.customers elected to source their needs in the spot market. Spot contract rates, remained above term contract rates duringwhich include the 2016 first quarter, fluctuated around term contract rates during the 2016 second quarter and fellcost of fuel, were meaningfully below term contract rates during the 2016 third2017 first quarter.

Marine Transportation Costs and Expenses

Costs and expenses for the 2016 third2017 first quarter and first nine months decreased 7% and 6%, respectively,increased 1% when compared with the 2015 third2016 first quarter and first nine months. Costs of sales and operating expenses for the 2016 third quarter and first nine months decreased 8% and 9%, respectively, compared with the third quarter and first nine months of 2015, primarily reflecting lower business activity levels, lowerdue to higher fuel costs, due to the decline in the price of diesel fuel andpartially offset by fewer inland towboats operated.

The inland marine transportation fleet operated an average of 227235 towboats during the 2016 third2017 first quarter, of which an average of 69 towboats72 were chartered, compared with 246240 during the 2015 third quarter, of which an average of 76 towboats were chartered. During the 2016 first nine months, the inland operations operated an average of 236 towboats, of which an average of 78 towboats were chartered, compared with 249 towboats operated during the 2015 first nine months,quarter, of which an average of 79 were chartered. As demand, or anticipated demand, increases or decreases, as new tank barges are added to the fleet, as chartered towboat availability changes, or as weather or water conditions dictate, such as the high wind and heavy ice and high waterfog conditions that occurred in the 20162017 first quarter, the Company charters-incharters in or releases chartered towboats in an effort to balance horsepower needs with current requirements. The Company has historically used chartered towboats for approximately one-third of its horsepower requirements.

During the 2016 third2017 first quarter, the inland operations consumed 9.810.6 million gallons of diesel fuel compared to 10.810.1 million gallons consumed during the 2015 third2016 first quarter. The average price per gallon of diesel fuel consumed during the 2016 third2017 first quarter was $1.59$1.78 per gallon compared with $1.91$1.27 per gallon for the 2015 third quarter. For the 2016 first nine months, the inland operations consumed 29.8 million gallons of diesel fuel compared to 32.6 million gallons consumed during the 2015 first nine months. The average price per gallon of diesel fuel consumed during the 2016 first nine months was $1.40 compared with $2.00 for the 2015 first nine months.quarter. Fuel escalation and de-escalation clauses on term contracts are designed to rebate fuel costs when prices decline and recover additional fuel costs when fuel prices rise; however, there is generally a 30 to 90 day delay before the contracts are adjusted. Spot contracts do not have escalators for fuel.

Taxes, other than on income, for the 2016 third quarter and first nine months increased 1% and 6%, respectively, compared with the 2015 third quarter and first nine months.  The increase for the 2016 first nine months over the 2015 first nine months was mainly due to an increase in the inland waterways user tax rate effective April 1, 2015.

Selling, general and administrative expenses for the 2016 third2017 first quarter decreased 8%15% compared with the 2015 third quarter and were flat for the 2016 first nine months compared to the 2015 first nine months,quarter, primarily a reflection of a $3,792,000 severance charge in the 2016 first quarter and the resulting cost savings in the 2017 first quarter from the reduction in force in early 2016, second and third quarters, partially offset by salary increases effective August 1, 2016.

Depreciation and amortizationTaxes, other than on income for the 2016 third2017 first quarter and first nine months increased 1% and 4%, respectively,26% compared with the 2015 third2016 first quarter, mainly due to higher property taxes on marine transportation equipment and first nine months. The increases were primarily attributable to the Seacor acquisition and increased capital expenditures in both the inland and coastal fleets, including new inland tank barges and towboats, as well as a coastal 185,000 barrel ATB placed in service in the fourth quarter of 2015 and a second coastal 185,000 barrel ATB placed in service in the second quarter of 2016.state franchise taxes effective January 1, 2017.

There are numerous factors that may negatively impact the Company’s cash flow in 2016.2017. For a list of significant risks and uncertainties that could impact cash flows, see Note 12,11, Contingencies, in the financial statements, and Item 1A — Risk Factors and Note 12,13, Contingencies and Commitments, in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015.2016.

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 $14,162,000$13,593,000 at September 30, 2016,March 31, 2017, including $4,057,000$4,034,000 in letters of credit and $10,105,000$9,559,000 in performance bonds.  All of these instruments have an expiration date within fourthree 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.

29

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

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

33

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 impact the 20162017 interest expense by $68,000$172,000 based on balances outstanding at December 31, 2015,2016, and would change the fair value of the Company’s debt by less than 1%.

Item 4.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 (“Exchange Act”)) as of September 30, 2016.March 31, 2017. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that, as of September 30, 2016,March 31, 2017, the disclosure controls and procedures were effective to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. There were no changes in the Company’s internal control over financial reporting during the quarter ended September 30, 2016March 31, 2017 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
