FORWARD-LOOKING STATEMENTS

Statements in this report not based on historical facts are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 and, accordingly, involve known and unknown risks and uncertainties that are difficult to predict and could cause our actual results, performance, or achievements to differ materially from those discussed. These statements include statements as to our future expectations, beliefs, plans, strategies, objectives, events, conditions, financial performance, prospects, or future events. In some cases, forward-looking statements can be identified by the use of words such as “may,” “could,” “expect,” “intend,” “plan,” “seek,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “outlook,” “continue,” “likely,” “will,” and “would”, and similar words and phrases. Forward-looking statements are necessarily based on estimates and assumptions that, while considered reasonable by us and our management, are inherently uncertain. Accordingly, you should not place undue reliance on forward-looking statements, which speak only as of the date they are made, and are not guarantees of future performance. We do not undertake any obligation to publicly update or revise these forward-looking statements.

A detailed discussion of the known material risks and uncertainties that could cause actual results and events to differ materially from such forward-looking statements is included in our Annual Report on Form 10-K for the year ended December 31, 2016,2017, and in our other filings with the Securities and Exchange Commission ("SEC"). The following factors, in addition to those discussed under "Risk Factors", in our Annual Report on Form 10-K for the year ended December 31, 2016,2017, could cause actual results to differ materially from our current expectations expressed in forward looking statements:
exposure to damages, fines, criminal and civil penalties, and reputational harm arising from a negative outcome in litigation, including claims arising from an accident involving our railcars
inability to maintain our assets on lease at satisfactory rates due to oversupply of railcars in the market or other changes in supply and demand
weak economic conditions and other factors that may decreasea significant decline in customer demand for our railcars or other assets andor services, including as a result of:
decreased demand for portions ofweak macroeconomic conditions
weak market conditions in our railcar fleet due to customers' businesses
declines in harvest or production volumes
adverse changes in the price of, or demand for, commodities that are shipped
changes in railroad operations or efficiency
changes in supply chains
availability of pipelines, trucks, and other alternative modes of transportation
other operational or commercial needs or decisions of our railcarscustomers
higher costs associated with increased railcar assignments following non-renewal of leases, customer defaults, and compliance maintenance programs or other maintenance initiatives
events having an adverse impact on assets, customers, or regions where we have a concentrated investment exposure
financial and operational risks associated with long-term railcar purchase commitments, including increased costs due to tariffs or trade disputes
reduced opportunities to generate asset remarketing income
operational and financial risks related to our affiliate investments, including the Rolls-Royce & Partners Finance joint ventures (collectively the “RRPF affiliates”"RRPF affiliates")
the impact of changes to the Internal Revenue Code as a result of the Tax Cuts and Jobs Act of 2017 (the "Tax Act"), and uncertainty as to how this legislation will be interpreted and applied.
fluctuations in foreign exchange rates
failure to successfully negotiate collective bargaining agreements with the unions representing a substantial portion of our employees
changes in railroad operations that could decrease demand for railcars, either due to increased railroad efficiency or decreased attractiveness of rail service relative to other modes
the impact of regulatory requirements applicable to tank cars carrying crude, ethanol, and other flammable liquids
asset impairment charges we may be required to recognize
deterioration of conditions in the capital markets, reductions in our credit ratings, or increases in our financing costs
competitive factors in our primary markets, including competitors with a significantly lower cost of capital than GATX
risks related to our international operations and expansion into new geographic markets, including the imposition of new or additional tariffs, quotas, or trade barriers
changes in, or failure to comply with, laws, rules, and regulations
inability to obtain cost-effective insurance
environmental remediation costs
inadequate allowances to cover credit losses in our portfolio
inability to maintain and secure our information technology infrastructure from cybersecurity threats and related disruption of our business

GATX CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)



NOTE 1. Description of Business

As used herein, "GATX," "we," "us," "our," and similar terms refer to GATX Corporation and its subsidiaries, unless indicated otherwise.

We lease, operate, manage, and remarket long-lived, widely-used assets, primarily in the rail market. We report our financial results through fourprimary business segments: Rail North America, Rail International, Portfolio Management, and American Steamship Company (“ASC”), and Portfolio Management..

NOTE 2. Basis of Presentation

We prepared the accompanying unaudited consolidated financial statements in accordance with USU.S. Generally Accepted Accounting Principles ("GAAP") for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, our unaudited consolidated financial statements do not include all of the information and footnotes required for complete financial statements. We have included all of the normal recurring adjustments that we deemed necessary for a fair presentation. Certain prior year amounts have been reclassified to conform to the 2018 presentation.

Operating results for the nine months ended September 30, 2017,2018 are not necessarily indicative of the results we may achieve for the entire year ending December 31, 2017.2018. In particular, ASC's fleet is inactive for a significant portion of the first quarter of each year due to winter conditions on the Great Lakes. In addition, asset remarketing income does not occur evenly throughout the year. For more information, refer to the consolidated financial statements and footnotes in our Annual Report on Form 10-K for the year ended December 31, 2016.2017.

New Accounting Pronouncements Adopted

Equity Method and Joint Ventures
Standard/DescriptionEffective Date and Adoption ConsiderationsEffect on Financial Statements or Other Significant Matters
Revenue from Contracts with Customers
In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-07, Investments - Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting, which eliminates the requirement to retrospectively apply equity method accounting when an entity increases ownership or influence in a previously held investment. The new guidance was effective for us in the first quarter of 2017. Application of the new guidance did not impact our financial statements or related disclosures.

Stock Compensation

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which simplifies and clarifies certain aspects of share-based payments accounting and presentation. The update requires recognition of excess tax benefits and tax deficiencies, which arise due to differences between the measure of compensation expense and the amount deductible for tax purposes, to be recorded directly through earnings as a component of income tax expense. Previously, these differences were generally recorded in additional paid-in capital and thus had no impact on net income. The change in treatment of excess tax benefits and tax deficiencies also impacts the computation of diluted earnings per share, and the cash flows associated with those items are classified as operating activities on the consolidated statements of cash flows. The guidance also clarifies that all cash payments made to taxing authorities on the employees' behalf for withheld shares should be classified as financing activities on the consolidated statements of cash flows. Additionally, the guidance permits entities to make an accounting policy election for the impact of forfeitures on the recognition of expense for share-based payment awards. Forfeitures can be estimated as of the initial valuation date, as allowed under the previous guidance, or recognized when they occur. We changed our accounting policy to recognize forfeitures when they occur as part of this adoption. These amendments became effective in the first quarter of 2017, and we adopted this guidance as of January 1, 2017. Adoption of this new standard did not have a material impact on our financial statements or related disclosures.
In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09,
Revenue from Contracts with Customers(Topic 606), which supersedes most current revenue recognition guidance, including industry-specific guidance. Subsequently, the FASB has issued updates which provide additional implementation guidance. The new guidance requires companies to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration it expects to be entitled to in exchange for those goods or services.


We adopted this guidance in the first quarter of 2018 applying the modified retrospective approach.


We have completed our review of all revenue sources in scope for the new standard, and marine operating revenue is our largest component. In accordance with the new standard, the basis for determining revenue and expenses allocable to in-process shipments has been modified; however, the impact does not have a material impact on our financial statements. The net cumulative effect adjustment for this change was immaterial to retained earnings as of January 1, 2018.
Financial Instruments

In January 2016, the FASB issued ASU 2016-01,
Financial Instruments - Overall (Topic 825): Recognition and Measurement of Financial Assets and Financial Liabilities, which modifies the accounting and reporting requirements for certain equity securities and financial liabilities.


We adopted the new guidance in the first quarter of 2018.


The application of this new guidance did not impact our financial statements or related disclosures.
GATX CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (Continued)


Statement of Cash Flows

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which clarifies the classification and presentation of changes in restricted cash on the statement of cash flows. We elected to early adopt the new guidance as of January 1, 2017, using the retrospective method. Application of the new guidance requires presentation of restricted cash together with cash and cash equivalents on the consolidated statements of cash flows and eliminates the disclosure of the related changes in restricted cash within investing activities.

New Accounting Pronouncements Not Yet Adopted (Continued)
Standard/DescriptionEffective Date and Adoption ConsiderationsEffect on Financial Statements or Other Significant Matters
Income Taxes

In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which modifies how an entity will recognize the income tax consequences of an intra-entity transfer of an asset when the transfer occurs.


We adopted the new guidance in the first quarter of 2018, applying the modified retrospective method.


The application of this new guidance had an immaterial impact on our financial statements and related disclosures, including the net cumulative effect adjustment recorded in retained earnings as of January 1, 2018.
Compensation

In March 2017, the FASB issued ASU 2017-07,
Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which modifies how an entity must present service costs and other components of net benefit cost.


We adopted the new guidance in the first quarter of 2018, applying the retrospective method. The optional practical expedient was elected.


Application of the new guidance had an immaterial impact on the presentation of our financial statements as certain components of our net periodic pension and other post-retirement benefits costs were reclassified to an alternative income statement line.
Deferred Income Tax

ber 2017, the FASB issued ASU 2017-15, Codification Improvements to Topic 995, U.S. Steamship Entities, which supersedes obsolete guidance in Topic 995 on unrecognized deferred taxes related to certain statutory reserve deposits. If an entity has unrecognized deferred income taxes related to statutory deposits made on or before December 15, 1992, the entity would be required to recognize the unrecognized income taxes in accordance with Topic 740.


We elected to early adopt this new guidance in the first quarter of 2018, applying the modified retrospective method.


The application of this new guidance had an immaterial impact on our financial statements and related disclosures, including the net cumulative effect adjustment recorded in retained earnings as of January 1, 2018.
Accumulated Other Comprehensive Income

In February 2018, the FASB issued ASU 2018-02,
Income Statement Reporting - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which permits reclassification of certain stranded tax effects from the Tax Cuts and Jobs Act from Accumulated Other Comprehensive Income to Retained Earnings. The amount of the reclassification is calculated on the basis of the difference between the historical and newly enacted tax rates recorded for the applicable AOCI components.


We adopted the new guidance in the first quarter of 2018.


The application of this new guidance resulted in the reclassification of stranded tax effects resulting from the newly enacted Tax Act of $19.4 million from Accumulated Other Comprehensive Income to Retained Earnings.

Revenue from Contracts with Customers

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes most current revenue recognition guidance, including industry-specific guidance. Subsequently, the FASB has issued updates which provide additional implementation guidance. The new guidance requires companies to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration it expects to be entitled to in exchange for those goods or services. The FASB delayed the effective date of this guidance to the first quarter of 2018, with early adoption permitted as of the original effective date of the first quarter of 2017. We plan to adopt this guidance as of January 1, 2018, using the modified retrospective approach. Our primary source of revenue is lease revenue, which will continue to be within the scope of existing lease accounting guidance upon adoption of Topic 606. We have substantially completed our review of all other revenue sources in scope for the new standard and have concluded the new guidance will not have a material impact on our financial statements.

Leases

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which supersedes most current lease guidance. The new guidance requires companies to recognize most leases on the balance sheet and modifies accounting, presentation, and disclosure for both lessors and lessees. The new guidance is effective for us in the first quarter of 2019, with early adoption permitted. We plan to adopt this guidance on January 1, 2019, using a modified retrospective transition method, and we expect to utilize the package of three optional practical expedients as provided in the standard. We continue to assess the effect the new guidance will have on our consolidated financial statements and related disclosures.

Financial Instruments

In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Topic 825): Recognition and Measurement of Financial Assets and Financial Liabilities, which modifies the accounting and reporting requirements for certain equity securities and financial liabilities. The new guidance is effective for us beginning in the first quarter of 2018, with certain provisions eligible for early adoption. We do not expect the new guidance to have a significant impact on our financial statements or related disclosures.

Credit Losses

In June 2016, the FASB issued ASU 2016-13, Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which modifies how entities will measure credit losses. The new guidance is effective for us in the first quarter of 2020, with early adoption permitted. We are evaluating the effect the new guidance will have on our financial statements and related disclosures.

Statement of Cash Flows

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which clarifies the classification of certain cash receipts and payments in the statement of cash flows. The new guidance is effective for us in the first quarter of 2018, with early adoption permitted. We do not expect the new guidance to have a significant impact on our financial statements or related disclosures.

NOTE 3. Revenue

Adoption of Accounting Standards Codification Topic 606, “Revenue from Contracts with Customers”

In the first quarter of 2018, we adopted Topic 606 using the modified retrospective method with respect to applicable contracts existing as of January 1, 2018. As provided in the guidance, we recognize marine operating revenue in the amount that corresponds directly to the value transferred to the customer. Contract assets and liabilities related to our customer performance obligations are not material to our financial statements. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts have not been adjusted and continue to be reported in accordance with appropriate accounting guidance. We recorded an immaterial cumulative adjustment to opening retained earnings, with the impact completely attributable to our marine operating revenue.

Revenue Recognition

Revenue is recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services.

We disaggregate revenue into three categories as presented on our income statement:

Lease Revenue

Lease revenue, which includes operating lease revenue and finance lease revenue, is our primary source of revenue which continues to be within the scope of existing lease guidance. Therefore, the adoption of Topic 606 had no impact on our recognition or presentation of lease revenue.

Operating Lease Revenue

We lease railcars and other operating assets under full-service and net operating leases. We price full-service leases as an integrated service that includes amounts related to executory costs, such as maintenance, insurance, and ad valorem taxes. We do not offer stand-alone maintenance service contracts and are unable to separate executory costs from full-service lease revenue. Operating lease revenue, including amounts related to executory costs, is recognized on a straight-line basis over the term of the underlying lease. As a result, we may not recognize lease revenue in the same period as maintenance and other executory costs, which we expense as incurred. Contingent rents are recognized when the contingency is resolved. Revenue is not recognized if collectability is not reasonably assured.

Finance Lease Revenue

In certain cases, we lease railcars and other operating assets that, at lease inception, are classified as finance leases. We recognize unearned income as lease revenue using the interest method, which produces a constant yield over the lease term. Initial unearned income is the amount that the original lease payment receivable and the estimated residual value of the leased asset exceeds the original cost or carrying value of the leased asset.

Marine Operating Revenue

We generate marine operating revenue through shipping services completed by our marine vessels. Upon adoption of Topic 606, marine operating revenue is recognized over time as the performance obligation is satisfied, beginning when cargo is loaded through its delivery and discharge. Revenue is recognized pro rata over the projected duration of each voyage, which is derived from our historical voyage data.

Other Revenue

Other revenue comprises customer liability repair revenue, utilization income, fee income, interest on loans, and other miscellaneous revenues. Select components of other revenue are within the scope of Topic 606 but based on our assessment, we determined that our

current revenue elements and timing for purposes of income recognition are consistent with applicable provisions in the new standard. The remaining items are considered lease components that continue to be within the scope of existing lease guidance.

We value derivatives using a pricing model with inputs (such as yield curves and foreign currency rates) that are observable in the market or that can be derived principally from observable market data.

Derivative instruments

Fair Value Hedges

We use interest rate swaps to manage the fixed-to-floating rate mix of our debt obligations by converting thea portion of our fixed rate debt to floating rate debt. For fair value hedges, we recognize changes in fair value of both the derivative and the hedged item as interest expense. We had eightnine instruments outstanding with an aggregate notional amount of $450.0$500.0 million as of September 30, 2017 that mature2018 with maturities ranging from 20182019 to 2022 and eightten instruments outstanding with an aggregate notional amount of $550.0 million as of December 31, 20162017 with maturities ranging from 20172018 to 2020.2022.

GATX CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (Continued)


Cash Flow Hedges

We use interest rate swaps to convert floating rate debt to fixed rate debt. We use Treasury rate locks and swap rate locks to hedge our exposure to interest rate risk on anticipated transactions. We also use currency swaps to hedge our exposure to fluctuations in the exchange rates of the foreign currencies in which we conduct business. We had eleven8 instruments outstanding with an aggregate notional amount of $290.2$291.1 million as of September 30, 20172018 that mature from 20172018 to 2022 and ninefive instruments outstanding with an aggregate notional amount of $412.1$285.6 million as of December 31, 20162017 with maturities ranging from 20172019 to 2022. Within the next 12 months, we expect to reclassify $5.2$2.9 million ($3.32.2 million after-tax) of net losses on previously terminated derivatives from accumulated other comprehensive income (loss) to interest expense or operating lease expense, as applicable. We reclassify these amounts when interest and operating lease expense on the related hedged transactions affect earnings.

Non-designated Derivatives

We do not hold derivative financial instruments for purposes other than hedging, although certain of our derivatives are not designated as accounting hedges. We recognize changes in the fair value of these derivatives in other (income) expense immediately.

Some of our derivative instruments contain credit risk provisions that could require us to make immediate payment on net liability positions in the event that we default on certain outstanding debt obligations. The aggregate fair value of our derivative instruments with credit risk related contingent features that are in a liability position as of September 30, 2017,2018 was $23.7$34.7 million. We are not required to post any collateral on our derivative instruments and do not expect the credit risk provisions to be triggered.

In the event that a counterparty fails to meet the terms of an interest rate swap agreement or a foreign exchange contract, our exposure is limited to the fair value of the swap, if in our favor. We manage the credit risk of counterparties by transacting with institutions that we consider financially sound and by avoiding concentrations of risk with a single counterparty. We believe that the risk of non-performance by any of our counterparties is remote.

Other Financial Instruments

The carrying amounts of cash and cash equivalents, restricted cash, rent and other receivables, accounts payable, and commercial paper and bank credit facilities approximate fair value due to the short maturity of those instruments. We base the fair values of investment funds, which are accounted for under the cost method, on the best information available, which may include quoted investment fund values. We estimate the fair values of loans and fixed and floating rate debt using discounted cash flow analyses that are based on interest rates currently offered for loans with similar terms to borrowers of similar credit quality. The inputs we use to estimate each of these values are classified in Level 2 of the fair value hierarchy because they are directly or indirectly observable inputs.

The following table shows the carrying amounts and fair values of our other financial instruments (in millions):

U.S. taxation of earnings repatriated from our foreign subsidiaries and affiliates. Other provisions included an immediate deduction for qualified investments and limitations on the deductibility of interest expense and executive compensation. Due to our net operating loss position, these adjustments had no cash impact on our tax positions.

In 2017, we recorded a one-time non-cash net tax benefit of $315.9 million, which represented our provisional estimate of the impact of the Tax Act. This amount included a net benefit of $371.4 million associated with the re-measurement of our net deferred tax liability utilizing the lower U.S. tax rate. The Tax Act also imposed a one-time transitional repatriation tax of $57.2 million on certain undistributed earnings of our non-U.S. subsidiaries and affiliates.

We continue to evaluate the provisions of the Tax Act, and the ultimate impact may differ from this provisional estimate, due to, among other things, changes in interpretations and assumptions made by us, additional guidance that may be issued by the Internal Revenue Service and the U.S. Department of the Treasury, and actions that we may take. In addition, these estimates may change due to guidance provided by state taxing authorities and the completion of our 2017 U.S. and state income tax returns. No adjustments were made to our initial provisional estimate during the nine months ended September 30, 2018.

Our effective tax rate was 26% for the nine months ended September 30, 2018, compared to 32% for the nine months ended September 30, 2017, compared to 33% for the nine months ended September 30, 2016.2017. The difference in the effective rates for the current year compared to the prior year is primarily attributable to the reduction in the U.S. corporation income tax rate from 35% to 21%, as part of the Tax Act. Additionally, the effective tax rate was impacted by the mix of pre-tax income among domestic and foreign jurisdictions, which are taxed at different rates. Additionally, during the quarter, based upon the status of our current state incomeIncremental tax audits and our expectations of the ultimate resolution, we released the remaining balance of our liability for unrecognized tax benefits and recognized an income tax benefit of $4.3 million ($2.8 million, net of federal tax). Also, our consolidated state income tax rate increased, effective July 1, 2017, due to legislation enacted in the state of Illinois. Accordingly, we recorded a deferred state income tax adjustment of $3.1 million in the quarter. Finally, the 2017 effective tax rate reflects incremental benefits associated with equity awardsshare-based compensation were also recognized in accordance witheach of the adoption of new accounting rulesnine-month periods ended September 30, 2018 and the impact of reductions in the statutory tax rates in Quebec and Saskatchewan, Canada and India, partially offset by an increase to the effective tax rate in Germany.2017.

NOTE 8. Commercial Commitments

We have entered into various commercial commitments, such as guarantees, standby letters of credit, and performance bonds, related to certain transactions. These commercial commitments require us to fulfill specific obligations in the event of third-party demands. Similar to our balance sheet investments, these commitments expose us to credit, market, and equipment risk. Accordingly, we evaluate these commitments and other contingent obligations using techniques similar to those we use to evaluate funded transactions.

The carrying value of liabilities on the balance sheet for commercial commitments was $2.3 million at September 30, 2017 and $3.0 million at December 31, 2016. The expirations of these commitments range from 2017 to 2023.
(1) The carrying value of liabilities on the balance sheet for commercial commitments was $1.2 million at September 30, 2018 and $2.0 million at December 31, 2017. The expirations of these commitments range from 2019 to 2023. We are not aware of any event that would require us to satisfy any of our commitments.

Lease payment guarantees are commitments to financial institutions to make lease payments for a third party in the event they default. We reduce any liability that may result from these guarantees by the value of the underlying asset or group of assets.

We are also parties to standby letters of credit and performance bonds, which primarily relate to contractual obligations and general liability insurance coverages. No material claims have been made against these obligations, and no material losses are anticipated.

NOTE 9. Earnings per Share

We compute basic earnings per share by dividing net income available to our common shareholders by the weighted average number of shares of our common stock outstanding. We weightedweight shares issued or reacquired during the period for the portion of the period that they were outstanding. Our diluted earnings per share reflect the impacts of our potentially dilutive securities, which include our equity compensation awards.

NOTE 11. Legal Proceedings and Other Contingencies

Various legal actions, claims, assessments and other contingencies arising in the ordinary course of business are pending against GATX and certain of our subsidiaries. These matters are subject to many uncertainties, and it is possible that some of these matters could ultimately be decided, resolved or settled adversely. For a full discussion of our pending legal matters, please refer to "Note 22. Legal Proceedings and Other Contingencies" of our consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2016.2017.

Viareggio Derailment

In June 2009, a train consisting of fourteen liquefied petroleum gas (“LPG”) tank cars owned by GATX Rail Austria GmbH and its subsidiaries (collectively, “GRA”) derailed while passing through the City of Viareggio, in the province of Lucca, Italy. Five tank cars overturned and one of the overturned cars was punctured by a peg or obstacle along the side of the track, resulting in a release of LPG, which subsequently ignited. The accident resulted in multiple deaths, personal injuries and property damage. The LPG tank cars were leased to FS Logistica S.p.A., a subsidiary of the Italian state-owned railway, Ferrovie dello Stato S.p.A (the “Italian Railway”).

On December 14, 2012, the prosecutors for Lucca charged the Italian Railway, GRA, and a number of their maintenance, operations, and managerial employees with various negligence-based crimes related to the accident. A trial was held in the court of Lucca and, on January 31, 2017, the court announced guilty verdicts against various Italian Railway companies, GRA, and certain of their employees. The court imposed a fine of 1.4 million Euros against GRA and prison sentences against the employees. GRA disagrees with the trial court’s ruling and believes that the evidence shows it and its employees acted diligently and in accordance with all applicable laws and regulations at all times. On October 14, 2017, GRA filed its appeal of the trial court’s ruling with the Court of Appeal in Florence (Corte d’Appello di Firenze) and, pending the final disposition of the appeal, these fines and penalties are not enforceable.

With respect to civil claims, the insurers for the Italian Railway and GRA have fully settled and resolved most of the claims arising out of the accident. With respect to unsettled claims, the Lucca court ordered all convicted defendants (including various Italian Railway entities and GRA) to pay final damages or advances to the remaining 56 claimants. The amount of these awards is immaterial and GRA expects that its insurers will continue to cover most of these damages to claimants except for a small number of civil claims. GRA will continue to incur legal expenses for the criminal appeals although they are not expected to be material. We cannot predict the outcome of the appeals process and thus cannot reasonably estimate the possible amount or range of costs that may be ultimately incurred in connection with this litigation.

NOTE 12. Financial Data of Business Segments

The financial data presented below depicts the profitability, financial position, and capital expenditures of each of our business segments.

We lease, operate, manage, and remarket long-lived, widely-used assets, primarily in the rail market. We report our financial results through four primary business segments: Rail North America, Rail International, Portfolio Management, and American Steamship Company (“ASC”), and Portfolio Management..

Rail North America is composed of our wholly owned operations in the United States, Canada, and Mexico, as well as an affiliate investment. Rail North America primarily provides railcars pursuant to full-service leases under which it maintains the railcars, pays ad valorem taxes and insurance, and provides other ancillary services.

Rail International is composed of our wholly owned European operations in Europe ("GATX Rail Europe" or "GRE"), our wholly owned railcar leasing business in India ("Rail India"), and our wholly owned operations in Russia.Russia ("Rail Russia"). GRE leases railcars to customers throughout Europe pursuant to full-service leases under which it maintains the railcars and provides value-adding services according to customer requirements.

ASC operates the largest fleet of US-flagged vessels on the Great Lakes, providing waterborne transportation of dry bulk commodities such as iron ore, coal, limestone aggregates, and metallurgical limestone.

Portfolio Management is composed primarily of our ownership in a group of joint ventures with Rolls-Royce plc that lease aircraft spare engines, as well as five liquefied gas carrying vessels (the "Norgas Vessels") and assorted other marine assets. In prior years, Portfolio Management

We are inIn 2015, we made the process of disposing ofdecision to exit the majority of the marine investments, excluding the Norgas Vessels, within our Portfolio Management segment, including six chemical parcel tankers, a number of inland marine vessels, and our 50% interest in this segment.the Cardinal Marine joint venture, all of which had been sold as of December 31, 2017.

ASC operates the largest fleet of US-flagged vessels on the Great Lakes, providing waterborne transportation of dry bulk commodities such as iron ore, coal, limestone aggregates, and metallurgical limestone.

Segment profit is an internal performance measure used by the Chief Executive Officer to assess the performance of each segment in a given period. Segment profit includes all revenues, pre-tax earnings from affiliates, and net gains on asset dispositions that are attributable to the segments, as well as expenses that management believes are directly associated with the financing, maintenance, and operation of the revenue earning assets. Segment profit excludes selling, general and administrative expenses, income taxes, and certain other amounts not allocated to the segments. These amounts are included in Other.

We allocate debt balances and related interest expense to each segment based upon predetermined debt to equity leverage ratios. The leverage levels are 5:1 for Rail North America, 3:1 for Rail International, 1.5:1 for ASC, and 1:1 for Portfolio Management.Management, and 1.5:1 for ASC. We believe that by using this leverage and interest expense allocation methodology, each operating segment’s financial performance reflects appropriate risk-adjusted borrowing costs.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

BUSINESS OVERVIEW

We lease, operate, manage, and remarket long-lived, widely-used assets, primarily in the rail market. We report our financial results through four primary business segments: Rail North America, Rail International, Portfolio Management, and American Steamship Company (“ASC”), and Portfolio Management..

The following discussion and analysis should be read in conjunction with the MD&A in our Annual Report on Form 10-K for the year ended December 31, 2016.2017. We based the discussion and analysis that follows on financial data we derived from the financial statements prepared in accordance with USU.S. Generally Accepted Accounting Standards ("GAAP") and on certain other financial data that we prepared using non-GAAP components. For a reconciliation of these non-GAAP components to the most comparable GAAP components, see “Non-GAAP Financial Measures” at the end of this item.

Operating results for the three and nine months ended September 30, 20172018 are not necessarily indicative of the results we may achieve for the entire year ending December 31, 2017.2018. In particular, ASC's fleet is inactive for a significant portion of the first quarter of each year due to winter conditions on the Great Lakes. In addition, asset remarketing income does not occur evenly throughout the year. For more information about our business, refer to our Annual Report on Form 10-K for the year ended December 31, 2016.2017.

Net income was $159.9$162.1 million, or $4.04$4.21 per diluted share, for the first nine months of 20172018 compared to $226.2$159.9 million, or $5.49$4.04 per diluted share, in 2016.2017. Results for the nine months ended September 30, 2018 included costs of approximately $5.8 million (after-tax) associated with the closure of a maintenance facility at Rail International, and results for the nine months ended September 30, 2017 and 2016, included a net gainsgain of approximately $1.1 million and $2.1 million, respectively, associated with(after-tax) from the planned exit of the majority of Portfolio Management's marine investments. In addition, during the nine months ended September 30, 2016, net proceeds of $30.3 million were recorded as a result of the settlement of a residual sharing agreement, and a $3.9 million benefit from deferred income tax adjustments was recorded due to enacted statutory rate decreases in the United Kingdom. Seeinvestments (see "Non-GAAP Financial Measures" at the end of this item for further details.details). Excluding the impact of these items, net income decreased $31.1increased $9.1 million compared to the prior year.

The increase was driven by higher asset disposition gains and lower maintenance expense at Rail North America, higher lease revenue, resulting from more railcars on lease, and the positive impacts of foreign exchange rates, both at Rail International, and higher income from affiliates. These positive impacts were partially offset by lower lease revenue at Rail North America, due to lower lease rates and fewer railcars on lease, as well as lower residual sharing fees from our managed portfolio and lower marine operating results at our Portfolio Management segment.
Net income was $49.0$47.0 million, or $1.25$1.22 per diluted share, for the third quarter of 20172018 compared to $95.7$49.0 million, or $2.36$1.25 per diluted share, in 2016. Results for the third quarter of 2016 included net gains of approximately $0.4 million associated with the planned exit of the majority of Portfolio Management's marine investments. In addition, during the third quarter of 2016, net proceeds of $30.3 million were recorded as a result of the settlement of a residual sharing agreement, and a $3.9 million benefit from deferred income tax adjustments was recorded due to enacted statutory rate decreases in the United Kingdom. See "Non-GAAP Financial Measures" at the end of this item for further details. Excluding the impact of these items, net2017. Net income decreased $12.1$2.0 million compared to the prior year.
The decreases in both the quarter and year-to-date net income for 2017 were primarily driven by lower disposition gains anddecrease was largely due to lower lease revenue, at Rail North America, resulting fromas a result of lower lease rates and fewer railcars on lease. In the prior year, disposition gains forlease at Rail North America, as well as lower affiliate income. These negative impacts were partially offset by lower maintenance expense at Rail North America, as well as higher lease revenue, resulting from more railcars on lease, and lower maintenance expense, both the quarter and year-to-date included sizeable residual sharing fees from the managed portfolio at our Portfolio Management segment.Rail International.

SEGMENT OPERATIONSSegment Operations

Segment profit is an internal performance measure used by the Chief Executive Officer to assess the performance of each segment in a given period. Segment profit includes all revenues, pre-tax earnings from affiliates, and net gains on asset dispositions that are attributable to the segments, as well as expenses that management believes are directly associated with the financing, maintenance, and operation of the revenue earning assets. Segment profit excludes selling, general and administrative expenses, income taxes, and certain other amounts not allocated to the segments. These amounts are included in Other.

We allocate debt balances and related interest expense to each segment based upon predetermined debt to equity leverage ratios. The leverage levels are 5:1 for Rail North America, 3:1 for Rail International, 1.5:1 for ASC, and 1:1 for Portfolio Management. Management, and 1.5:1 for ASC.We believe that by using this leverage and interest expense allocation methodology, each operating segment’s financial performance reflects appropriate risk-adjusted borrowing costs.


RAIL NORTH AMERICA

Segment Summary

Challenging conditions continue in the North American railcar leasing market due to the oversupply of existing railcars and a large railcar manufacturing backlog. Despite this difficultThe operating environment for Rail North America has been successful in maintaining high utilization of its railcars across all tankcontinued to improve, as railroad car loadings increased and freight types.

railroad velocity decreased relative to 2017. Despite absolute lease rates improving, revenue pressure continues. At September 30, 2017,2018, Rail North America's wholly owned fleet, excluding boxcars, consisted of approximately 103,700 cars. Fleet103,400 cars, and fleet utilization excluding boxcars, was 98.5% at the end of September 30, 2017, compared to 98.8% at the end of prior quarter, and 99.0%99.2% at September 30, 2016. Fleet utilization for approximately 16,600 boxcars was 92.4% at the end of September 30, 2017,2018, compared to 90.2%98.9% at the end of the prior quarter, and 98.5% at September 30, 2017. Fleet utilization for our approximately 16,000 boxcars was 94.7% at September 30, 2016.2018, compared to 92.8% at the end of the prior quarter, and 92.4% at September 30, 2017.

For the third quarter of 2018, an average of approximately 102,100 railcars, excluding boxcars, were on lease, compared to 101,300 in the prior quarter and 102,600 at September 30, 2017. The decrease in railcars on lease in the current year is largely due to railcars that

were sold or scrapped, consistent with our ongoing strategy to optimize the composition of our fleet. During the third quarter of 2017,2018, the renewal rate change of the Lease Price Index (the "LPI", see definition below) decreased 27.0%was negative 11.5%, compared to decreases of 21.4%negative 16.1% in the prior quarter and 21.4%negative 27.0% in the third quarter of 2016.2017. Lease terms on renewals for cars in the LPI averaged 3533 months in the current quarter, compared to 3241 months in the prior quarter, and 2935 months in the third quarter of 2016.2017. Additionally, the renewal success rate, which represents the percentage of expiring leases that were renewed with the existing lessee, was 74.9%82.9% in the current quarter, compared to 75.1%78.6% in the prior quarter, and 74.1%74.9% in the third quarter of 2016.2017. Railcars returned by our customers may incur transitional costs, including additional repairs and related service prior to being leased to new customers, which may increase maintenance and associated expenses.

In 2014, we entered into a long-term supply agreement with Trinity Rail Group, LLC ("Trinity"), a subsidiary of Trinity Industries that took effect in mid-2016. Under the terms of that agreement, we may order up to 8,950 newly built railcars over a four-year period from March, 2016 through March, 2020. We may order either tank or freight cars; however, we expect that the majority of the order will be for tank cars. As of September 30, 2018, 7,715 railcars have been ordered, of which 5,095 railcars have been delivered. On May 24, 2018, we amended our long-term supply agreement with Trinity to extend the challenging lease rate environment persists,term to December 2023. We agreed to purchase an additional 4,800 tank cars (1,200 per year) beginning in January 2020 and continuing through the expiration of the extended term. Pricing will be on an agreed upon or cost-plus basis subject to certain adjustments and surcharges specified in the agreement.

On July 30, 2018, we entered into a multi-year railcar supply agreement with American Railcar Industries, Inc. ("ARI"), pursuant to which we will continuepurchase 7,650 newly built railcars. The order encompasses a mix of tank and freight cars to experience pressure onbe delivered over a five-year period, beginning in April 2019. ARI will deliver 450 railcars in 2019, with the LPI. Forremaining 7,200 to be delivered ratably over the third quarterfour-year period of 2017,2020 to 2023.

Lease Price Index

Our LPI is an internally-generated business indicator that measures lease rate pricing on renewals for our North American railcar fleet, excluding boxcars. We calculate the index using the weighted average lease rate for a group of railcar types that we believe best represents our overall North American fleet, excluding boxcars. The average renewal lease rate change is reported as the percentage change between the average renewal lease rate and the average expiring lease rate, weighted by fleet composition. The average renewal lease term is reported in months and reflects the average renewal lease term of railcar types in the LPI, weighted by fleet composition.

Comparison of the First Nine Months of 20172018 to the First Nine Months of 20162017

Segment Profit

SegmentIn the first nine months of 2018, segment profit wasof $241.3 million increased 1.3% compared to $238.1 million in the same period in the prior year. The increase was driven by higher asset disposition gains and lower maintenance expense, partially offset by lower lease revenue and lower termination fees.

Revenues

In the first nine months of 2018, lease revenue decreased $22.1 million, or 3.3%, primarily due to lower lease rates and fewer railcars on lease. Other revenue decreased $8.9 million, largely a result of lower termination fees in the current period, partially offset by higher repair revenue. Other revenue in 2017 included $7.8 million of compensation for damage to returned railcars. The expenses to repair these railcars are recognized as incurred.


Expenses

In the first nine months of 2018, maintenance expense decreased $9.5 million, largely due to fewer tank qualifications, lower assignment-related costs, and fewer repairs performed by the railroads. Maintenance expenses will likely increase in the fourth quarter of 2018 and into 2019 as tank car compliance service events increase. Depreciation expense increased $7.0 million due to new railcar investments and the purchase of railcars previously on operating leases. Operating lease expense decreased $7.8 million, resulting from the purchase of railcars previously on operating leases in both 2018 and 2017.

Other Income (Expense)

In the first nine months of 2018, net gain on asset dispositions increased $25.8 million, attributable to more railcars sold in the current year, as well as higher scrapping gains resulting primarily from a higher scrap price per ton. Net interest expense increased $3.0 million, driven by a higher average debt balance.

Investment Volume

During the first nine months of 2018, investment volume was $414.7 million compared to $333.7 million in the same period in 2017. We acquired 3,045 newly built railcars and purchased 793 railcars in the secondary market in the first nine months of 20172018, compared to $273.42,532 newly built railcars and 212 railcars purchased in the secondary market in the same period in 2017.

Our investment volume is predominantly composed of acquired railcars, but also includes certain capitalized repairs and improvements to owned railcars and our maintenance facilities. As a result, the dollar value of investment volume does not necessarily correspond to the number of railcars acquired in any given period. In addition, the comparability of amounts invested and the number of railcars acquired in each period is impacted by the mix of railcars purchased, which may include tank cars and freight cars, as well as newly manufactured railcars or those purchased in the secondary market.

Comparison of the Third Quarter of 2018 to the Third Quarter of 2017

Segment Profit

In the third quarter of 2018, segment profit of $68.2 million decreased 2.8% compared to $70.2 million in the same period in the prior year. The decrease was driven by lower lease revenue and higher maintenance expense,other revenue, partially offset by higher asset disposition gains.lower maintenance expense.

Revenues

LeaseIn the third quarter of 2018 lease revenue decreased $25.6$6.3 million, in the first nine months of 2017,or 2.8%, primarily due to lower lease rates and fewer railcars on lease. Other revenue decreased $3.5$2.7 million, in the first nine months of 2017 due to lower repair revenueexcess mileage and lower lease termination fees. Other revenue in 2016 included a lease termination fee of approximately $10.0 million for allowing a customer to return railcars prior to the contractual end of an existing lease. Other revenue in the current year included $7.8 million for compensation of damages to returned cars. The expenses to repair these cars will be recognized as incurred. In some cases, it may be more economical to scrap the railcar rather than incur these expenses.

Other Income (Expense)

NetIn the third quarter of 2018, net gain on asset dispositions increased $6.2$1.5 million, in the first nine months of 2017, in part dueattributable to higher average net gains on railcarmore railcars sold and locomotive sales. In addition, higher scrapping gains resulting from more railcars scrapped and higher scrap prices, were partially offset by an impairment loss recorded in the current year, on certain railcars.partially offset by the absence of net gains from locomotives sold in the prior year. The higher scrapping gains were due to higher scrap prices that more than offset fewer railcars scrapped. Net interest expense increased $8.9$1.3 million, in the first nine months of 2017, due todriven by a higher average interest rate and a higher average debt balance. Other expense in the first nine months of 2017 was comparable to the same period in the prior year.

Investment Volume

During the first nine months of 2017, investment volume was $333.7 million compared to $366.7 million in the same period in 2016. We acquired 2,532 newly built railcars and purchased 212 railcars in the secondary market in the first nine months of 2017, compared to 2,361 newly built railcars and 25 railcars purchased in the secondary market in the same period in 2016.

Comparison of the Third Quarter of 2017 to the Third Quarter of 2016

Revenues

Lease revenue decreased $8.5 million in the third quarter of 2017, primarily due to lower lease rates and fewer cars on lease. Other revenue in the third quarter of 2017 was comparable to the same period in the prior year.

Expenses

Maintenance expense increased $3.3 million in the third quarter of 2017, primarily due to an increase in costs associated with cars assigned to new lessees, partially offset by lower expenses for the boxcar fleet and lower repairs performed by the railroads. Depreciation expense increased $1.7 million in the period, largely due to new investments. Operating lease expense decreased $1.7 million in the third quarter of 2017, resulting from the purchase of railcars previously on operating leases in both years. Other operating expense decreased $1.3 million in the period, primarily due to lower switching and freight costs.

Other Income (Expense)

Net gain on asset dispositions decreased $5.0 million in the third quarter of 2017, primarily due to fewer railcars sold in the current year, as well as lower scrapping gains. Net interest expense increased $3.4 million in the third quarter of 2017, due to a higher average interest rate and a higher average debt balance.

RAIL INTERNATIONAL

Segment Summary

Rail International, composed primarily of GATX Rail Europe ("GRE"), produced solid operating results in 2017. Despite pressure on lease rates,the first nine months of 2018. In Europe, we continue to see gradual, broad improvement across the chemical, petroleum, and freight markets, and GRE benefited from stable demand, leading to successwas successful in maintaining high fleet utilization.utilization across all railcar types in the third quarter of 2018. Railcar utilization for GRE was 95.6%98.4% at the end of the third quarter of 2017,September 30, 2018, compared to 95.7%97.8% at the end of the prior quarter and 95.0%95.6% at September 30, 2016.2017. In addition, Rail India and Rail Russia benefited from more cars on lease as they continue to expand their fleets.

GRE's results in 2016 were impacted by higher wheelset costs,In the second quarter of 2018, GRE recorded $8.6 million of expense attributable to the closure of a refurbishment program enacted to address anti-corrosion paint issues on certain wheelsets.railcar maintenance facility in Germany.

Our investment volume is predominantly composed of acquired railcars, but may also include certain capitalized repairs and improvements to owned railcars. As a result, the dollar value of investment volume does not necessarily correspond to the number of railcars acquired in any given period. In addition, the comparability of amounts invested and the number of railcars acquired in each period is impacted by the mix of the various car types acquired, as well as fluctuations in the exchange rates of the foreign currencies in which Rail International conducts business.

Foreign Currency

Rail International's reported results of operations are impacted by fluctuations in the exchange rates of the foreign currencies in which it conducts business, primarily the euro. In the third quarter of 2018, a weaker euro negatively impacted lease revenue by approximately $0.5 million and segment profit, excluding other income (expense), by approximately $0.3 million compared to the same period in 2017.

PORTFOLIO MANAGEMENT

Segment Summary

Portfolio Management's segment profit includesis primarily attributable to income from our investment in the Rolls-Royce & Partners Finance companies (collectively the "RRPF affiliates").RRPF affiliates. The RRPF affiliates are a group of sixteeneighteen 50% owned domestic and foreign joint ventures with Rolls-Royce plc (or affiliates thereof, collectively “Rolls-Royce”), a leading manufacturer of commercial aircraft jet engines. Segment profit included earnings from the RRPF affiliates of $47.6 million and $14.3 million for the nine months and three months ended September 30, 2018, compared to $38.8 million and $15.3 million for the first nine months and third quarter of 2017, compared to $32.0 million and $14.2 millionsame periods in 2016.2017. As of September 30, 2017,2018, the RRPF affiliates owned 409439 aircraft spare engines with a net book value of approximately $3,959 million, compared to 410432 aircraft spare engines with a net book value of approximately $3,764 million at September 30, 2016.

Portfolio Management's results also include the operations of five liquefied gas carrying vessels (the "Norgas Vessels"). During the first nine months of 2017, the Norgas Vessels experienced lower rates, due in part to the impact of new competing vessels that entered the market during the current year, as well as lower utilization of our vessels resulting from supply disruptions caused by unplanned outages at certain customers' petrochemical plants.December 31, 2017.

As we have disclosed previously, we made the decision to exit the majority of our marine investments, including six chemical parcel tankers (the "Nordic Vessels"), most of our inland marine vessels, and our 50% interest in the Cardinal Marine joint venture. To date,As of December 31, 2017, we havehad completed theall planned sales of the Nordic Vessels,marine assets, including our 50% interest in the Cardinal Marine joint venture, and the majority of our inland marine assets. In the first nine months of 2017, we soldventure.

Portfolio Management continues to own other marine assets, consisting primarily of five liquefied gas-carrying vessels (the "Norgas Vessels"). The Norgas Vessels specialize in the transport of pressurized gases and chemicals, such as liquefied petroleum gas, liquefied natural gas, and ethylene, primarily on shorter-term spot contracts for total proceeds of $28.2 million, resulting in a net gain of $1.8 million. In the first nine months of 2016, we sold marine assets for total proceeds of $48.4 million, resulting in a net gain of $4.2 million. We

expect to sell the remaining targeted inland marine assets in 2017. Upon completion of these sales, Portfolio Management will continue to ownmajor oil and operate some marine investments, primarily the Norgas Vessels.chemical customers worldwide.

Portfolio Management's total asset base was $614.9 million at September 30, 2018, compared to $582.8 million at December 31, 2017, and $616.8 million at September 30, 2017, compared to $593.5 million at December 31, 2016, and $606.2 million at September 30, 2016. Assets held for sale were $19.2 million at September 30, 2017, $45.6 million at December 31, 2016, and $60.5 million at September 30, 2016.2017.

SG&A, Unallocated Interest and Other

During the third quarter GATX early terminatedof 2017, we exercised our option to terminate the office lease at itsour corporate headquarters.headquarters early. As a result, accelerated depreciation on leasehold improvementsimprovement was recorded in SG&A, and certain associatedlease termination costs were recorded in SG&A and Otherother expense (income), respectively..

SG&A increased $1.0$9.8 million infor the first nine months of 2017, due to a combination of higher compensation2018 and employee benefits costs, accelerated depreciation expense$4.0 million for leasehold improvements, and higher information technology expense, substantially offset by the impact of a settlement accounting adjustment recorded in the prior year attributable to the early retirement program offered to eligible employees. SG&A decreased $5.3 million in the third quarter of 2017, driven by the impact of the settlement accounting adjustment noted above, partially offset by2018, both variances primarily due to higher employee compensation expenses and accelerated depreciation forof leasehold improvements and higher information technology expense.beginning in the prior year. The negative impacts of changes in foreign exchange rates also contributed to the increase compared to the prior year nine-month period.

Unallocated interest expense (the difference between external interest expense and interest expense allocated to the reporting segments in accordance with assigned leverage targets) in any year is affected by our consolidated leverage position, the timing of debt issuances and investing activities, and intercompany allocations.

We generate a significant amount of cash from operating activities and from our investment portfolio proceeds. We also access domestic and international capital markets by issuing unsecured or secured debt and commercial paper. We use these resources, along with our available cash balances, to fulfill our debt, lease, and dividend obligations, to support our share repurchase program,programs, and to fund portfolio investments and capital additions. We primarily use cash from operations and commercial paper issuances to fund daily operations.

The timing of asset dispositions and changes in working capital impactsimpact cash flows from portfolio proceeds and operations. As a result, these cash flow components may vary materially from quarter to quarter and year to year. As of September 30, 2017,2018, we had an unrestricted cash balance of $199.2$254.5 million.

Net cash provided by operating activities of $317.5$341.3 million decreased $118.0increased $23.5 million compared to 2016.2017. The decreaseincrease was driven by lower operating lease payments and the timing of interest payments, as well as the positive impact of changes in foreign exchange rates. These positive drivers were partially offset by lower lease revenue, lower affiliate dividends, and lower fee income, which included $9.8$1.7 million of residual sharing income in 20172018 compared to $83.2$9.8 million in 2016, lower contributions from our marine operations at Portfolio Management, and lower lease revenue. In addition, the net impact of changes in the balances of certain working capital items negatively impacted cash provided from operating activities.2017.

Portfolio proceeds primarily consist of loan and finance lease receipts, proceeds from sales of operating assets and loan and finance lease receipts. Portfolio proceeds of $198.6 million for the nine months of 2018 increased by $67.6 million from the prior year, primarily due to higher proceeds from sales of securities, and capital distributionsrailcars at Rail North America, partially offset by lower proceeds from affiliates. Portfolio proceeds included net proceeds of $28.2 million in 2017 and $48.4 million in 2016 from the sales of marine investments as part of our decision to exit the majority of the marine assets at our Portfolio Management segment.Management.

Rail North America completed a sale-leaseback financingsfinancing for 467 railcars in the third quarter of 2018 and 699 railcars in the first nine monthssecond quarter of 2017 and 574 railcars in the first nine months of 2016.

Proceeds from the issuance of debt for the first nine months ended September 30, 2018 were $297.1 million (net of 2017 werehedges and debt issuance costs), compared to $308.6 million (net of hedges and debt issuance costs), primarily attributable to in the same period in 2017. In each of 2018 and 2017, a $300 million,$300-million, 10-year unsecured financing that was completed. In the first nine months of 2016, proceeds, net of hedges and debt issuance costs, of $801.8 million included a $350 million 10-year unsecured offering, a $200 million 5-year unsecured financing, and a $150 million 50-year unsecured offering, as well as $125 million drawn and subsequently repaid on a secured railcar funding facility. Debt repayments of $301.5$267.3 million for the first nine months of 20172018 were $499.7$34.2 million lower than prior year. Each yearRepayments in both years consisted of scheduled maturity payments. Debt repayments in 2016 also includedpayments and the early retirements. Additionally, we extended the maturitiesretirement of certain of our credit facilities and loans in the second quarter of 2017.debt issuances.


Portfolio investments and capital additions primarily consist of purchases of operating assets, investments in affiliates, and capitalized asset improvements. Portfolio investments and capital additions of $459.0$536.7 million for the first nine months of 2018 increased $16.4$77.7 million compared to 2016, primarily2017, due to more railcars acquired at Rail North America and Rail International, partially offset by the absence of investments at the RRPF affiliates at Portfolio Management partially offset by lower investments at Rail North America resulting fromin the mix and related cost of railcars purchased as part of our long-term supply agreement.prior year.

Purchases of leased-in assets of $93.2$66.6 million for the first nine months of 2018 decreased $23.3$26.6 million compared to 2016. Athe same period in 2017. The decrease was attributable to a $24.0 million decrease at ASC, related to the purchase of $47.3a vessel in 2017 that was previously on lease, and a $2.6 million decrease at Rail North America due to fewer railcars purchased was partially offset by a $24.0 million increase at ASC for the purchase of a vessel that was previously on lease.in 2018 (1,232 railcars in 2018 compared to 1,815 railcars in 2017).

In the first quarter ofOn January 29, 2016, our boardBoard of directors authorizedDirectors (the "Board") approved a $300 million share repurchase program, pursuant to which we are authorized to purchase shares of our common stock in the open market, in privately negotiated transactions, or otherwise, including pursuant to Rule 10b5-1 plans. As of December 31, 2017, $80.0 million remained available under this program. On January 26, 2018, the Board approved an additional share repurchase authorization of $170 million, bringing our aggregate available repurchase authorization to $250 million. During the nine months ended September 30, 2017,2018, we acquired 0.5 million shares of common stock for $37.4 million, compared to 1.2 million shares of common stock for $75.0 million compared to 2.2 million shares for $95.0 million during the same period in 2016.2017.

(3)Primarily railcar purchase commitments. The amounts shown for all years are based on management's estimates of the timing, anticipated car types, and related costs of railcars to be purchased under its agreements.

In 2014, we entered into a long-term supply agreement with Trinity Rail Group, LLC ("Trinity"), a subsidiary of Trinity Industries Inc. that took effect in mid-2016. Under the terms of that agreement, we may order up to 8,950 newly built railcars over a four-year period from March, 2016 through March, 2020. We may order either tank or freight cars; however, we expect that the majority of the order will be for tank cars. PursuantAs of September 30, 2018, 7,715 railcars have been ordered, of which 5,095 railcars have been delivered. On May 24, 2018, we amended our long-term supply agreement with Trinity to extend the termsterm to December 2023. We agreed to purchase an additional 4,800 tank cars (1,200 per year) beginning in January 2020 and continuing through the expiration of the extended term. Pricing will be on an agreed upon or cost-plus basis subject to certain adjustments and surcharges specified in the agreement.

On July 30, 2018, we entered into a multi-year railcar supply agreement the parties conducted a review of the contract pricing in January 2017 as it no longer reflected market rates. Based on this review, the parties agreed to reduce contract pricing for future orderswith American Railcar Industries, Inc. ("ARI"), pursuant to which we will purchase 7,650 newly built railcars. The order encompasses a mix of tank and freight cars to be delivered over a five-year period, beginning in April 2019. ARI will deliver 450 railcars in 2019, with the termsremaining 7,200 to be delivered ratably over the four-year period of the agreement.2020 to 2023. The agreement also includes an option to order up to an additional 4,400 railcars subject to certain restrictions.

Credit Lines and Facilities

We have a $600 million, 5-year unsecured revolving credit facility in the US that matures inU.S. In the second quarter of 2018, we extended the maturity on this facility by one year from May 2022.2022 to May 2023. As of September 30, 2017,2018, the full $600 million was available under the facility. Additionally, we have a $250 million 5-year secured railcar funding facility in the USU.S. with a 3-year revolving period that matures in May 2022. As of September 30, 2017,2018, the full $250 million was available under this facility.

Restrictive Covenants

Our $600 million revolving credit facility contains various restrictive covenants, including requirements to maintain a fixed charge coverage ratio and an asset coverage test. CertainSome of our other financingsbank term loans have the same financial covenants as the facility.
The indentures for our public debt also contain various restrictive covenants, including limitations on liens provisions that limitrestrict the amount of additional secured indebtedness that we may incur. Additionally, certain exceptions to the covenants permit us to incur an unlimited amount of purchase money and nonrecourse indebtedness.

The loan agreements for certain of our European rail subsidiaries also contain restrictive covenants, including leverage and cash flow covenants specific to those subsidiaries, restrictions on making loans, and limitations on the ability of those subsidiaries to repay loans or to distribute capital to certain related parties (including GATX, the USU.S. parent company). These covenants effectively limit GRE's ability to transfer funds to GATX.

We do not anticipate any covenant violations nor do we anticipateexpect that any of these covenants will restrict our operations or our ability to obtain additional financing. At September 30, 2017,2018, we were in compliance with all covenants and conditions of all of our credit agreements.

Credit Ratings

The global capital market environment and outlook may affect our funding options and our financial performance. Our access to capital markets at competitive rates depends on our credit rating and ratingsrating outlook, as determined by rating agencies. As of September 30, 2017, 2018,

our long-term unsecured debt was rated BBB by Standard & Poor's and Baa2 by Moody’s InvestorsInvestor Service and our short-term unsecured debt was rated A-2 by Standard & Poor's and P-2 by Moody’s InvestorsInvestor Service. Our rating outlook from both agencies was stable.


CRITICAL ACCOUNTING POLICIES AND ESTIMATES

There have been no changes to our critical accounting policies during the nine months ended September 30, 2017.2018. Refer to our Annual Report on Form 10-K for the year ended December 31, 2016,2017, for a summary of our policies.

NON-GAAP FINANCIAL MEASURES
    
In addition to financial results reported in accordance with GAAP, we compute certain financial measures using non-GAAP components, as defined by the SEC. These measures are not in accordance with, or a substitute for, GAAP, and our financial measures may be different from non-GAAP financial measures used by other companies. We have provided a reconciliation of our non-GAAP components to the most directly comparable GAAP components.

Reconciliation of Non-GAAP Components Used in the Computation of Certain Financial Measures

Balance Sheet Measures

We include total on- and off-balance sheet assets because a portion of our North American railcar fleet has been financed through sale-leasebacks that are accounted for as operating leases and are not recorded on the balance sheet. Similarly, ASC utilizesASC's fleet previously included vessels that arewere accounted for as operating leases and arewere not recorded on the balance sheet. We include these leased-in assets in our calculation of total assets (as adjusted) because we believe it gives investors a more comprehensive representation of the magnitude of the assets we operate and that drive our financial performance. In addition, this calculation of total assets (as adjusted) provides consistency with other non-financial information we disclose about our fleet, including the number of railcars in the fleet, average number of cars on lease, and utilization. We also provide information regarding our leverage ratios, which are expressed as a ratio of debt (including off-balance sheet debt) to equity. The off-balance sheet debt amount in this calculation is the equivalent of the off-balance sheet asset amount. We believe reporting this corresponding off-balance sheet debt amount provides investors and other users of our financial statements with a more comprehensive representation of our debt obligations, leverage, and capital structure.

Net Income Measures

We exclude the effects of certain tax adjustments and other items for purposes of presenting net income, diluted earnings per share, and return on equity because we believe these items are not attributable to our business operations. Management utilizes net income, excluding tax adjustments and other items, when analyzing financial performance because such amounts reflect the underlying operating results that are within management’s ability to influence. Accordingly, we believe presenting this information provides investors and other users of our financial statements with meaningful supplemental information for purposes of analyzing year-to-year financial performance on a comparable basis and assessing trends.
