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 ~~also invest in joint ventures that complement our existing business activities. We~~ report our financial results through four primary business segments: Rail North America, Rail International, American Steamship Company (“ASC”), and Portfolio Management.

NOTE 2. Basis of Presentation

We prepared the accompanying unaudited consolidated financial statements in accordance with US 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.

Operating results for the three months ended March 31, ~~2016,~~2017, are not necessarily indicative of the results we may achieve for the entire year ending December 31, ~~2016.~~2017. 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, ~~2015.~~2016.

~~Accounting Changes~~

~~Change in Accounting Estimate~~

At the end of 2015, we changed the approach used to measure service and interest costs for pension and other postretirement benefits. In prior years, the Company measured service and interest costs utilizing a single weighted-average discount rate derived from the yield curve used to measure the plan obligations. For 2016, we measured service and interest costs by applying the specific spot rates along that yield curve to the plans’ liability cash flows. The Company believes this approach provides a more precise measurement of service and interest costs by aligning the timing of the plans’ liability cash flows to the corresponding spot rates on the yield curve. This change does not affect the measurement of our plan obligations. The Company has accounted for this change as a change in accounting estimate and, accordingly, has accounted for it on a prospective basis. The Company's adoption of the full yield curve approach will reduce 2016 service and interest cost by approximately $4.5 million ($2.8 million after-tax) as compared to the previous method.

New Accounting Pronouncements Adopted

~~Consolidation~~Equity Method and Joint Ventures

In ~~February 2015,~~March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") ~~2015-02,~~2016-07, ~~Consolidation~~Investments - Equity Method and Joint Ventures (Topic ~~810) Amendments~~323): Simplifying the Transition to the ~~Consolidation Analysis~~Equity Method of Accounting, which ~~amends~~eliminates the ~~analysis required~~requirement to ~~determine whether to consolidate certain types of legal entities such as limited partnerships, limited liability corporations, and certain securitization structures.~~retrospectively apply equity method accounting when an entity increases ownership or influence in a previously held investment. The new guidance was effective for us ~~beginning~~ in the first quarter of ~~2016.~~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 payment 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 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.

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.

GATX CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (Continued)

~~Business Combinations~~

~~In September 2015, the FASB issued ASU 2015-16,~~ ~~Business Combinations (Topic 805), Simplifying the Accounting for Measurement-Period Adjustments,~~ which requires the acquirer in a business combination to recognize measurement-period adjustments in the period in which it determines the amount of the adjustment. The new guidance was effective for us in the first quarter of 2016. Application of the new guidance did not impact our financial statements or related disclosures.

New Accounting Pronouncements Not Yet Adopted

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 can adopt the new guidance using either the retrospective method or the cumulative effect transition method. We are evaluating the effect that the new guidance will have on our consolidated financial statements and related disclosures and when we will electplan to adopt this ~~standard.~~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. With respect to our other revenue elements, marine operating revenue is our biggest component. The new standard may modify the recognition timing of certain in-transit cargo revenue, but we do not expect such changes to 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, using a modified retrospective transition method. We plan to adopt this guidance on January 1, 2019, using a modified retrospective transition method. We are evaluating the effect that the new guidance will have on our consolidated financial statements and related ~~disclosures and when we will elect to adopt this standard.~~disclosures.

Financial Instruments

In January 2016, the FASB issued ASU 2016-01, Financial Instruments - ~~Overall:~~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.

~~NOTE 3. Variable Interest Entities~~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 are evaluating the effect the new guidance will have on our financial statements and related disclosures.

We are the primary beneficiary of one of our variable interest entities, a structured lease financing of a portfolio of railcars, because we have the power to direct its significant activities. As a result, we consolidate this variable interest entity. The risks associated with it are similar to those of our wholly owned railcar leasing activities.

We determined that we are not the primary beneficiary of our other variable interest entities, which are primarily investments in aircraft spare engine leasing affiliates that were financed through a variety of equity investments and third-party lending arrangements. We are not the primary beneficiary of these variable interest entities because we do not have the power to direct the activities that most significantly impact the entities’ economic performance. Rather, that power was shared by the affiliate partners based on the terms of the relevant joint venture agreements, which require approval of all partners for significant decisions regarding the variable interest entity.

Fair Value Hedges

We use interest rate swaps to manage the fixed-to-floating rate mix of our debt obligations by converting the 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.

Cash Flow Hedges

We use interest rate swaps to convert floating rate debt to fixed rate debt. We use Treasury 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 fifteen instruments outstanding with an aggregate notional amount of ~~$592.9~~$317.6 million as of March 31, ~~2016~~2017 that mature from ~~2016~~2017 to 2022 and ~~ten~~nine instruments outstanding with an aggregate notional amount of ~~$442.9~~$412.1 million as of December 31, ~~2015.~~2016 with maturities ranging from 2017 to 2022. Within the next 12 months, we expect to reclassify ~~$5.8~~$5.7 million ($~~3.6~~3.5 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 March 31, ~~2016,~~2017, was ~~$21.9 million~~.$2.0 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 ~~estimated fair~~inputs we use to estimate each of these values ~~for these investments~~ are classified in Level 2 of the fair value hierarchy because they are ~~based on~~ directly or indirectly observable inputs.

The difference in the effective rates for ~~each period,~~the current year compared to ~~the statutory rate of 35%,~~prior year is primarily attributable to the mix of pretax income ~~in each year~~ among domestic and foreign jurisdictions which are taxed at different rates. In addition, the effective tax rate reflects incremental benefits associated with equity awards in accordance with new accounting rules, as well as the impact on deferred taxes of reductions in the statutory tax rates in Quebec, Canada and India.

As of March 31, ~~2016,~~2017, our gross liability for unrecognized tax benefits was $4.3 million. If fully recognized, these tax benefits would decrease our income tax expense by $4.3 million ($2.8 million, net of federal tax). ~~During~~Based upon the ~~three months ended March 31, 2016,~~status of current state income tax audits and our expectation of the ultimate resolution, we ~~reduced our unrecognized~~believe that it is reasonably possible that we will recognize a tax benefit ~~by $1.4~~of $4.3 million ~~based on a final determination ruling for a disputed state tax filing position.

NOTE 9.8. 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.

(1)	The carrying value of liabilities on the balance sheet for commercial commitments was $2.8 million at March 31, 2017 and $3.0 million at December 31, 2016. The expirations of these commitments range from 2017 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~~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 ~~10.~~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 appropriately weighted 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.

In 2015, we completed our $250 million share repurchase authorization approved in 2014. On January 29, 2016, our board of directors authorized a new $300 million stock repurchase program. As of March 31, 2016, 1.2 million shares had been repurchased for $50.0 million.

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 ~~24.~~22.

~~Viareggio Derailment~~

In June 2009, a train consisting of fourteen liquefied petroleum gas (“LPG”) tank cars owned by GATX Rail Austria GmbH (an indirect subsidiary of the Company, "GATX Rail Austria") and its subsidiaries 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. Thirty-two people died and others were injured in the fire, which also resulted in 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”).

~~NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (Continued)~~

On December 14, 2012, the Public Prosecutors of Lucca ("Public Prosecutors") formally charged GATX Rail Austria and two of its subsidiaries (collectively, "GRA"), as well as ten maintenance and supervisory employees (the "Employees"), with various negligence-based crimes related to the accident, all of which are punishable under Italian law by incarceration, damages, and fines. Similar charges were brought against four Italian Railway companies and eighteen of their employees, among others. The Public Prosecutors assert that the axle on a tank car broke, causing the derailment and resulting in a tank rupture and release of LPG, after the car hit an obstacle placed on the side of the track by the Italian Railway. The Public Prosecutors further allege that a crack in the axle was detectable at the time of final inspection but was overlooked by the Employees at the Jungenthal Waggon GmbH workshop (a subsidiary of GATX Rail Austria). The trial in the Court of Lucca (the “Lucca Trial”) commenced on November 13, 2013.

With respect to civil claims, GRA’s insurers continue to work cooperatively with the insurer for the Italian Railway to adjust and settle personal injury and property damage claims. These joint settlement efforts have so far settled most of the significant civil claims related to the accident; however, approximately 80 civil claimants did not settle and are currently parties to the Lucca Trial. The Court of Lucca will determine both the civil and criminal liability of the defendants in the one proceeding. GRA expects that its insurers will cover any civil damages if awarded to the claimants in the Lucca trial. The Public Prosecutors and civil claimants have finished presenting their cases in the Lucca Trial. GRA, the Italian Railway, and the other defendants in the Lucca Trial began presenting the defense of their cases on September 16, 2015, which presentations are currently underway.

Since May 2012, one of the excess insurers providing coverage, Liberty Mutual Insurance Europe Limited (“Liberty”), settled civil claims but refused to reimburse GRA for its ongoing legal defense fees and costs, taking a position contrary to our other insurers in the prior underlying layers that had provided coverage for such expenses. As of March 31, 2016, GRA had incurred approximately $14.7 million in unreimbursed defense fees and costs, and GRA continues to incur costs in connection with the Lucca Trial. Consequently, in October 2013, GRA filed an arbitration proceeding against Liberty seeking to recoup its unreimbursed defense fees and costs (the “Liberty Arbitration”), which was heard in November 2015. GRA received a partial arbitration award in its favor and anticipates reimbursement of a portion its defense costs in relation to the Lucca Trial. GRA is currently negotiating issues of reimbursement for outstanding defense costs with the insurers in the current coverage layer, which also includes a 25% share held by Liberty.

While GRA believes that it and its Employees acted diligently and properly, we cannot predict the outcome of the Lucca Trial, the negotiations with our insurers, or what other legal proceedings or claims, if any, may be initiated against GRA or its personnel, and, therefore, cannot reasonably estimate the possible amount or range of loss that may ultimately be incurred in connection with this accident.

NOTE 1312. 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 ~~also invest in joint ventures that complement our existing business activities. We~~ report our financial results through four primary business segments: Rail North America, Rail International, ~~ASC,~~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 ("GATX Rail Europe" or "GRE"), ~~and~~ a wholly owned railcar leasing business in India ("Rail India"), ~~as well as one development stage affiliate~~and our operations in ~~China.~~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 ~~generates~~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 and assorted other marine assets. In prior years, Portfolio Management generated leasing, marine operating, asset remarketing, and management fee income through a collection of diversified wholly owned assets and joint venture investments. We are in the process of disposing of the majority of the marine investments ~~and managed assets.~~in this segment.

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, pretax 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. ~~Due to changes in the composition of our segments, we have modified segment leverage levels for 2016.~~ The leverage levels ~~for 2016~~ are 5:1 for Rail North America, 3:1 for Rail International, 1.5:1 for ASC, and 1:1 for Portfolio Management. ~~The leverage levels for 2015 were 5:1 for Rail North America, 2:1 for Rail International, 1.5:1 for ASC, and 3:1 for Portfolio Management.~~ We believe that by using this leverage and interest expense allocation methodology, each operating segment’s financial performance reflects appropriate risk-adjusted borrowing ~~costs~~.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 also invest in joint ventures that complement our existing business activities.~~ We report our financial results through four primary business segments: Rail North America, Rail International, 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, ~~2015.~~2016. We based the discussion and analysis that follows on financial data we derived from the financial statements prepared in accordance with ~~GAAP~~US 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 months ended March 31, ~~2016~~2017 are not necessarily indicative of the results we may achieve for the entire year ending December 31, ~~2016.~~ 2017. 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 ourAnnual Report on Form 10-K for the year ended December 31, ~~2015.~~2016.

DISCUSSION OF OPERATING RESULTS

	2017		2016
ROE (GAAP)	18.2	%	16.4	%
ROE, excluding tax adjustments and other items (non-GAAP)	16.8	%	18.6	%

Net income was $57.5 million, or $1.44 per diluted share, for the first quarter 2017 compared to $69.3 million, or $1.66 per diluted share, ~~for the first quarter of 2016 compared to $62.2 million, or $1.39 per diluted share,~~ in ~~2015.~~2016. Results in the first quarter of 2016 included a gain of approximately $1.5 million, net of tax, associated with the planned exit of the majority of Portfolio Management's marine investments (see "Non-GAAP Financial Measures" at the end of this item for further details). Excluding the impact of the gain, net income ~~increased $5.6~~decreased $10.3 million compared to the prior year, ~~driven by higher~~the result of lower lease revenue, ~~higher fees,~~lower marine operating results, and ~~lower~~higher selling, general, and administrative expenses, partially offset by ~~lower~~higher disposition gains.

Segment Operations

We allocate debt balances and related interest expense to each segment based upon predetermined debt to equity leverage ratios. ~~Due to changes in the composition of our segments, we have modified segment leverage levels for 2016.~~ The leverage levels ~~for 2016~~ are 5:1 for Rail North America, 3:1 for Rail International, 1.5:1 for ASC, and 1:~~1 for Portfolio Management. The leverage levels for 2015 were 5:1 for Rail North America, 2:1 for Rail International, 1.5:1 for ASC, and 3:~~1 for Portfolio Management. We believe that by using this leverage and interest expense allocation methodology, each operating segment’s financial performance reflects appropriate risk-adjusted borrowing ~~costs.~~costs.

RAIL NORTH AMERICA

Segment Summary

~~Rail~~Continued railcar oversupply, a large manufacturing backlog, and low fleet utilization within the North America ~~is facing an increasingly challenging~~ market across many car types. The growing oversupply of many railcar types, excess new railcar manufacturing capacity, declining carloadings of certain commodities, and increases in railroad velocity have createdall combined to maintain pressure on lease rates ~~renewal success rate, and new car placements. However,~~across the ~~strategic steps~~fleet in the first quarter.

At March 31, ~~2016,~~2017, Rail North America's wholly owned fleet, excluding boxcars, consisted of approximately ~~105,400~~103,700 cars. Fleet utilization, excluding boxcars, was ~~98.9%~~99.1% at the end of ~~the first quarter of 2016~~March 31, 2017, compared to ~~99.1%~~98.9% at the end of prior quarter, and ~~99.3%~~98.9% at March 31, ~~2015.~~2016. Fleet utilization for approximately ~~18,300~~17,400 boxcars was ~~97.1%~~92.9% at the end of ~~the first quarter of 2016,~~March 31, 2017 compared to ~~97.7%~~93.8% at the end of the prior quarter and ~~92.8%~~97.1% at March 31, ~~2015.~~2016.

During the first quarter of ~~2016,~~2017, the Lease Price Index ~~on renewals~~ (the ~~“LPI”~~"LPI", see definition below) ~~increased 6.4%~~decreased 32.6%, compared to ~~an increase~~a decrease of ~~20.5%~~36.2% in the prior quarter and ~~43.2%~~an increase of 6.4% in the first quarter of ~~2015.~~2016. Lease terms on renewals for cars in the LPI averaged 3429 months in the current quarter, compared to 4329 months in the prior quarter, and 5934 months in ~~the~~ first quarter of ~~2015.~~2016. Additionally, the renewal success rate was ~~67.5%~~72.4% in the current quarter, compared to ~~81.8%~~64.7% in the prior quarter and ~~84.8%~~67.5% in the first quarter of ~~2015.~~2016. As ~~current market~~the challenging lease ~~rates decline,~~rate environment persists, we will continue to experience pressure on the LPI. For the first quarter of ~~2016,~~2017, an average of approximately ~~104,500~~103,000 railcars, excluding boxcars, were on lease, compared to ~~105,300~~103,700 in the prior quarter and ~~106,500~~104,500 in the first quarter of ~~2015.~~2016. The decrease in railcars on lease in the current year is largely due to railcars that were sold or scrapped in an effort to optimize the composition of our fleet.

As of March 31, ~~2016,~~2017, leases for approximately ~~10,300~~12,500 railcars in our term lease fleet and approximately ~~3,800~~4,550 boxcars are scheduled to expire over the remainder of ~~2016.~~2017. These amounts exclude railcars on leases that ~~were~~are scheduled to expire later in ~~2016~~2017 but have already been renewed or assigned to a new lessee.

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 Three Months of ~~2016~~2017 to the First Three Months of ~~2015~~2016

Segment Profit

Segment profit was ~~$108.7~~$93.0 million in the first quarter of ~~2016,~~2017, compared to ~~$105.8~~$108.7 million in the prior year.

~~North American Rail Regulatory Matters~~

On May 1, 2015, the Pipeline and Hazardous Materials Safety Administration of the US Department of Transportation (“PHMSA”) issued final rules that established new design standards for tank cars in flammable liquids service (the “PHMSA Rules”). The PHMSA Rules became effective on July 7, 2015, and all newly built tank cars for use in certain flammable liquids service were required to comply with the new design standards commencing on October 1, 2015. The PHMSA Rules also established standards for modifications to existing tank cars in certain flammable liquids service and deadlines for modifying or removing those cars from service. The US Congress subsequently adopted the Fixing America’s Surface Transportation Act (“FAST Act”), which changed certain requirements of the PHMSA Rules. Key changes included revisions to the design standards for modified cars, amendments to the modification deadlines, and expansion of the applicability of the new tank car design standards to all cars used in flammable liquids service. Under the FAST Act, the deadlines for modifying or removing existing tank cars from flammables service range from January 2018 to May 2029, depending on the type of car and the type of commodity carried. While several legal challenges to the PHMSA Rules are pending in the US Circuit Court for the District of Columbia, the tank car design standards and the deadlines for modifying or removing cars from service were enacted into law by the FAST Act, and therefore, are unlikely to be affected by the outcome of these legal challenges.

On May 1, 2015, Transport Canada (“TC”) issued final rules establishing new design standards for tank cars carrying flammable liquids in Canada (the “Canadian Rules”). The Canadian Rules became effective on May 20, 2015, and all newly built tank cars for use in flammable liquids service were required to comply with the new standards effective October 1, 2015. The Canadian Rules also established standards for modifications to existing tank cars in flammable liquids service and deadlines for modifying or removing cars from service ranging from May 2017 to May 2025, depending on the type of car and the type of commodity carried.

We have a fleet of approximately 124,000 railcars in North America, including approximately 13,500 tank cars currently used to transport flammable liquids that are affected by the new rules, of which approximately 4,100 are moving crude oil and ethanol. Over 90% of our affected tank cars have a compliance deadline of 2023 or later. We expect to modify some of the most modern of our affected tank cars to comply with the new standards. However, for the majority of the affected cars, we currently anticipate retiring, redeploying, or selling them rather than performing retrofits.

RAIL INTERNATIONAL

Segment Summary

Rail International, ~~particularly~~composed primarily of GATX Rail Europe ("~~GATX Rail Europe" or "GRE"~~GRE"), ~~continues~~continued to ~~achieve~~maintain high utilization of its railcars and produced solid operating results ~~with utilization remaining above 95% and market lease rates relatively consistent with expiring rates.~~in 2017. Railcar utilization for GRE was ~~95.1%~~95.0% at the end of the first quarter of ~~2016~~2017, compared to ~~95.8%~~95.6% at the end of the prior quarter and ~~95.9%~~95.1% at March 31, ~~2015.~~2016.

GRE's results in ~~the first quarter of~~ 2016 were impacted by higher wheelset costs, primarily due to a refurbishment program enacted to address ~~anti-corrosion~~corrosion paint issues on certain ~~existing~~ wheelsets. ~~GRE is addressing this issue with the wheelset supplier and pursuing warranty remedies.~~

Comparison of the First Three Months of ~~2016~~2017 to the First Three Months of ~~2015~~2016

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 first three months of ~~2016,~~2017, a weaker euro negatively impacted lease revenue by approximately ~~$1.1~~$1.5 million and segment profit, excluding other income (expense), by approximately ~~$0.6~~$0.7 million compared to the first three months of ~~2015.~~2016.

Segment Profit

Segment profit was ~~$12.6~~$13.4 million in the first quarter of ~~2016,~~2017, compared to ~~$21.8~~$12.6 million in the prior year. The ~~decrease~~increase was largely due to lower maintenance expense, primarily as a result of lower wheelset costs, and lower legal defense costs, partially offset by lower lease revenue.

Revenues

Lease revenue decreased $1.6 million in the first quarter of 2017, primarily due to the effects of a weaker euro, as noted above. Other revenue decreased $0.5 million, primarily due to lower compensation for damaged railcars and lower repair revenue.

Expenses

Maintenance expense decreased $2.5 million in the first quarter of 2017, primarily due to lower wheelset costs, as well as fewer railcar revisions and lower refurbishment costs. Depreciation expense and other operating expense were comparable to prior year.

Other Income (Expense)

Net gain on ~~the sale of a workshop in the~~asset dispositions was comparable to prior ~~year,~~year. Net interest expense increased $0.6 million, largely due to higher ~~maintenance~~average interest rates and higher average debt balances. Other expense ~~and~~decreased $0.7 million, largely due to lower legal costs, partially offset by the unfavorable impact of changes in foreign exchange rates on non-functional currency items ~~partially offset by higher lease revenue.~~

~~Revenues~~

Lease revenue increased $2.8 million in the first quarter of 2016, primarily due to more cars on lease at higher rates in the current year, partially offset by the effects of a weaker euro, as noted above. Other revenue decreased $0.3 million, primarily due to the absence of interest income on a loan that was repaid in the first quarter of 2015.

~~Expenses~~

~~Maintenance expense increased $3.6 million in the first quarter of 2016, primarily due to higher costs of wheelset replacements, as discussed above,~~ and the higher cost of railcar revisions. Depreciation expense increased $0.4 million, driven by the impact of new cars added to the fleet, partially offset by the effects of a weaker euro. Other operating expense increased $0.5 million, largely due to higher switching and freight costs.

~~Other Income (Expense)~~

Net gain on asset dispositions decreased $4.2 million in the first quarter of 2016, primarily due to a gain on the sale of a workshop in the prior year. Net interest expense increased $0.8 million, largely due to a higher average debt balance, partially offset by lower average interest rates. Other expense increased $2.2 million largely due to the unfavorable impact of changes in foreign exchange rates on non-functional currency items. In addition, expenses associated with the Viareggio matter were incurred in both years.derivatives.

Investment Volume

During the first quarter of ~~2016,~~2017, investment volume was ~~$22.0~~$18.7 million compared to ~~$41.4~~$22.0 million in the first quarter of ~~2015.~~2016. We acquired approximately 207 railcars in the first quarter of 2017 compared to 191 railcars in the first quarter of ~~2016 compared to 485 railcars in the first quarter of 2015.~~2016.

ASC

Segment Summary

~~Our~~ASC's fleet is largely inactive for the first three months of each year due to winter conditions on the Great Lakes. ~~The~~Freight volume in the first quarter ~~freight volume~~ is largely attributable to prior year commitments completed in January of each period. Our 2017 sailing season began in late March. Because of the mild winter weather, there was less ice coverage on the Great Lakes, which will benefit early season operations. During the first quarter of ~~2016,~~2017, we carried ~~0.6~~1.0 million net tons of freight compared to ~~0.8~~0.6 million net tons during the first quarter of ~~2015. Consistent with 2015, we expect that lower iron ore demand and shipments will continue throughout 2016, negatively impacting operating results.~~2016.

PORTFOLIO MANAGEMENT

Segment Summary

InA significant portion of Portfolio Management's segment profit is generated by the ~~third~~Rolls-Royce & Partners Finance companies (collectively the "RRPF affiliates"). The RRPF affiliates are a group of fifteen 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 $11.2 million for the first quarter of ~~2015, GATX management~~2017, compared to $10.1 million in 2016.

As we have disclosed previously, we made the decision to exit the majority of our marine investments, ~~within the Portfolio Management segment,~~ including six chemical parcel tankers (the "Nordic Vessels"), most of ~~the~~our inland marine vessels, and our 50% interest in the Cardinal Marine joint venture. ~~As a result,~~To date, we ~~sold certain~~completed the sales of ~~our marine investments during 2015, including~~all six of the Nordic Vessels, our 50% interest in the Cardinal Marine joint ~~venture. In~~venture, and the ~~first quarter~~majority of ~~2016, we sold additional marine investments, including three of the Nordic Vessels and other~~our inland marine ~~vessels. Proceeds from~~assets. No sales were completed in the first quarter of ~~2016 were $37.6~~2017; in the prior year quarter, we sold marine assets for net proceeds of $36.7 million, resulting in a net gain of $2.4 million. We expect to sell the remaining targeted inland marine ~~investments~~assets in ~~2016.~~2017. Upon completion of these sales, Portfolio Management will continue to own and operate other marine investments, consisting primarily of five liquefied gas carrying vessels (the "Norgas Vessels").

The Rolls-Royce & Partners Finance companies (collectively the "RRPF affiliates") reported solid results, which reflect continued strong demand for aircraft spare engines. The RRPF affiliates contributed $10.1 million to segment profit for the first quarter of 2016, compared to $11.6 million in 2015.

Portfolio Management's total asset base was $600.0 million at March 31, 2017, compared to $593.5 million at December 31, 2016, and $605.8 million at March 31, ~~2016, compared to $636.5 million at December 31, 2015, and $794.4 million at March 31, 2015.~~2016. Assets held for sale were $45.6 million at March 31, 2017 and December 31, 2016, and $69.6 million at March 31, ~~2016 and $103.4 million at December 31, 2015.~~2016.

Comparison of the First Three Months of ~~2016~~2017 to the First Three Months of ~~2015~~2016

Comparisons of reported results for the current year and the prior year are impacted by the ~~sale~~sales of marine investments.

Segment Profit

Segment profit was ~~$18.6~~$14.7 million for the first quarter of ~~2016,~~2017, compared to ~~$15.9~~$18.6 million for the prior year. ~~The current year~~Segment profit for 2016 included a net gain of approximately $2.4 million associated with the sale of certain marine investments. Excluding this gain, results ~~within~~for the Portfolio Management segment were ~~consistent with prior year.~~$1.5 million lower for the first quarter of 2017, primarily due to lower residual sharing gains from the managed portfolio and lower aggregate marine operating results, offset by higher earnings from affiliates and other income.

Revenues

Lease revenue decreased ~~$4.7~~$0.8 million in the first quarter of ~~2016,~~2017, primarily due to the impact of the sales of leased assets in ~~both years.~~2016. Marine operating revenue decreased ~~$1.0~~$5.6 million, largely due to lower revenue from the Norgas vessels, as well as the absence of revenue from the Nordic vessels that were sold ~~marine investments, partially offset by higher revenue from the Norgas Vessels.

Other income in 2017 reflects conditional proceeds that we received related to the sale of certain aircraft assets completed in a prior year. ~~Net interest expense decreased $3.0 million as a result of a lower average debt balance and lower average interest rates.~~

Share of affiliates' ~~earnings decreased $1.3~~pretax income increased $1.5 million in the first quarter of ~~2016~~2017, primarily due to ~~lower~~higher operating ~~income, partially offset by higher gains on engine sales~~results at the RRPF affiliates, as well as additional proceeds received in the ~~current year.~~first quarter of 2017 attributable to the prior Cardinal Marine affiliate sale.

CASH FLOW AND LIQUIDITY

We generate a significant amount of cash from operating activities and from our investment ~~portfolio.~~portfolio proceeds. We also access domestic and international capital markets by issuing unsecured or secured debt and commercial paper. We use these sources of cash, along with our available cash balances, to fulfill our debt, lease, and dividend obligations, to support our share repurchase program, 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 impacts cash flows from ~~operations~~portfolio proceeds and ~~portfolio proceeds.~~operations. As a result, these cash flow components may vary materially from quarter to quarter and year to year. As of March 31, ~~2016,~~2017, we had an unrestricted cash balance of ~~$216.2~~$155.2 million.

The following table shows our principal sources and uses of cash for the three months ended March 31, 2017 (in millions):

Net cash provided by operating activities of ~~$77.5~~$52.0 million ~~increased $21.7~~decreased $27.9 million compared to ~~2015.~~2016. The ~~increase~~decrease was ~~driven by higher~~primarily due to lower lease revenue and ~~fee income,~~lower contributions from our marine operations at Portfolio Management and ~~lower~~higher operating lease payments, partially offset by ~~higher~~lower interest payments and lower income tax ~~payments, as well as~~payments. In addition, the net impact of changes in the balances of certain working capital ~~items.~~items negatively impacted cash provided from operating activities.

Portfolio proceeds ~~for the first three months~~primarily consist of loan and finance lease receipts, proceeds from sales of operating assets, proceeds from sales of securities, and capital distributions from affiliates. In 2016, portfolio proceeds included net proceeds of ~~$98.4~~$36.7 million ~~decreased by $78.4 million compared to 2015, primarily due to proceeds received in the prior year~~ from the ~~repayment~~sales of ~~a loan. In January 2015, AAE Cargo AG repaid its outstanding loan in~~marine investments as part of our decision to exit the ~~amount~~majority of ~~€67.5 million ($76.4 million).~~the marine assets at our Portfolio Management segment.

Proceeds from the issuance of debt for the first three months of ~~2016~~2017 were ~~$332.5~~$297.9 million (net of hedges and debt issuance costs). In ~~2016,~~2017, a ~~$200 million 5-year~~$300-million, 10-year unsecured financing was completed. Additionally, ~~$125~~we extended the maturity on $180 million ~~was drawn on~~of a ~~new $250 million railcar facility.~~$200-million term loan by one year to May 2022.

Each year ~~included~~consisted of scheduled ~~maturities. In addition, the prior year included early retirement of higher cost debt and a $129.0 million repayment in Europe.~~maturity payments.

Portfolio investments and capital additions primarily consist of purchases of operating assets, investments in affiliates, and capitalized asset improvements. ~~See individual segment discussions for further information on investment volume.~~Portfolio investments and capital additions of $129.0 million decreased $11.2 million compared to 2016, largely due to lower railcar purchases at Rail North America.

Purchases of leased-in assets of $79.3 million decreased $13.5 million compared to 2016. The decrease was a result of fewer leased railcars purchased at Rail North America, partially offset by the purchase of a previously leased vessel at ASC.

In the first quarter of 2016, our board of directors authorized a $300 million share repurchase program. During the three months ended March 31, 2017, we acquired 0.4 million shares of stock for $25.0 million, compared to 1.2 million shares for $50.0 million during the same period in 2016. As of March 31, 2017, $155.0 million remained available under the repurchase authorization.

(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 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 ~~1.2 million shares had been acquired~~through March, 2020. We may order either tank or freight cars; however, we expect that the majority of the order will be for ~~$50.0 million.~~tank cars. Pursuant to the terms of the 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 orders pursuant to the terms of the agreement.

~~Revolving~~ Credit ~~Facility~~Lines and Facilities

~~As of March 31, 2016, we had~~We have a ~~$575~~$600 million, 5-year unsecured credit facility in the US that matures ~~on April 30, 2020.~~in May 2021. As of March 31, ~~2016,~~2017, the full ~~$575~~$600 million was available under the facility. Additionally, we have a $250 million 5-year secured railcar facility with a 3-year revolving period in the US that matures in February 2021. As of March 31, 2017, the full $250 million was available under this facility.

Restrictive Covenants

Our ~~$575~~$600 million revolving credit facility contains various restrictive covenants, including requirements to maintain a fixed charge coverage ratio and an asset coverage test. Certain of our other financings have the same financial covenants as the facility.

The indentures for our public debt also contain various restrictive covenants, including ~~limitation~~limitations on liens provisions that limit 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 ~~("GATX Rail Europe" or "GRE")~~ 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 US parent company). These covenants effectively limit GRE's ability to transfer funds to us.

We do not anticipate any covenant violations nor do we anticipate that any of these covenants will restrict our operations or our ability to obtain additional financing. At March 31, ~~2016,~~2017, 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 ratings outlook, as determined by rating agencies. As of March 31, ~~2016,~~2017, our long-term unsecured debt was rated BBB by Standard & Poor's and Baa2 by Moody’s Investors Service and our short-term unsecured debt was rated A-2 by Standard & Poor's and P-2 by Moody’s Investors Service. Our rating outlook from both agencies was stable.

(2) 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. The amount shown for 2017 includes $24.0 million related to an option we exercised to purchase a vessel that is currently on lease.

In 2014, we entered into a long-term supply agreement with Trinity Rail Group, LLC, a subsidiary of Trinity Industries, Inc., to take effect in 2016. Under terms of the agreement, we will purchase 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. Except to the extent the parties otherwise agree, railcar pricing will be on an agreed upon or cost-plus basis subject to certain specified adjustments and surcharges throughout the term of the agreement. In addition, in January, 2017, either party may initiate a review of the cost-plus basis pricing if it is not reflective of then-current market prices. If the parties cannot agree on revised cost-plus pricing (or otherwise agree that no changes are necessary), either party may, at its election, deliver to the other party a notice of its intent to terminate, and in such case, the agreement will automatically terminate 30 days thereafter, unless the non-terminating party agrees to a specified revised margin as set forth in the agreement.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

There have been no changes to our critical accounting policies during the three months ended March 31, ~~2016.~~2017. Refer to our Annual Report on Form 10-K for the year ended December 31, ~~2015,~~2016, for a summary of our policies.

NON-GAAP FINANCIAL MEASURES

WeIn 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. We include these non-GAAP financial measures to provide additional information and insight into our operating results and financial position. We use these measures in analyzing our financial performance from period to period and when making compensation decisions.

~~Glossary of Key Terms~~

~~Non-GAAP financial measures~~ — Numerical or percentage-based measures of a company’s historical performance, financial position, or liquidity calculated using a component different from that presented in the financial statements as prepared in accordance with GAAP.

~~Net income, excluding other items~~ ~~— Net income, excluding certain items that we believe are not necessarily related to our ongoing business activities.~~

~~Off-balance sheet assets~~ — Assets, primarily railcars, that are financed with operating leases and therefore not recorded on the balance sheet. We estimate the off-balance-sheet asset amount by calculating the present value of committed future operating lease payments using the interest rate implicit in each lease.

~~On-balance sheet assets~~ ~~— Total assets reported on the balance sheet.~~

~~Return on equity~~ ~~— Net income divided by average shareholders’ equity.~~

~~Return on equity, excluding other items~~ ~~— Net income, excluding certain items, divided by average shareholders’ equity.~~

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

Balance Sheet Measures

We ~~disclose~~include total on- and off-balance sheet assets because a portion of our North ~~America~~American railcar fleet has been financed through sale-leasebacks that are accounted for as operating leases and ~~the assets~~ are not recorded on the balance sheet. ~~Additionally,~~Similarly, ASC utilizes ~~a tug and barge unit and a vessel~~vessels that are accounted for as operating leases and ~~the assets~~ are not recorded on the balance sheet. We include these leased-in assets in our calculation of total assets (as adjusted) because we believe ~~this information provides~~it gives investors ~~with~~ a ~~better~~more comprehensive representation of the magnitude of the assets ~~deployed~~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 ~~businesses.~~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.

The following table shows total ~~on- and off-balance~~balance sheet assets (in millions):

Net Income Measures

We exclude the effects of certain tax adjustments and other items ~~when we present~~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 ~~diluted earnings per share. We exclude these~~other items, ~~to provide a more meaningful comparison of~~when analyzing financial performance ~~between years~~because such amounts reflect the underlying operating results that are within management’s ability to influence.
