NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1.         Description of Business

GATX Corporation (“GATX” or the “Company”) leases, operates, manages and remarkets long-lived, widely-used assets primarily in the rail and marine markets. GATX also invests in joint ventures that complement existing business activities. Headquartered in Chicago, Illinois, GATX has three financial reporting segments: Rail, American Steamship Company (“ASC”) and Portfolio Management.

NOTE 2.         Basis of Presentation

The accompanying unaudited consolidated financial statements of GATX Corporation and its subsidiaries have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by these accounting principles for complete financial statements. In the opinion of management, all adjustments (which are of a normal recurring nature) considered necessary for a fair presentation have been included. Operating results for the nine months ended September 30, 2012, are not necessarily indicative of the results that may be achieved for the entire year ending December 31, 2012. In particular, ASC’s fleet is generally inactive for a significant portion of the first quarter of each year due to the winter conditions on the Great Lakes. In addition, the timing of asset remarketing income is dependent, in part, on market conditions and, therefore, does not occur evenly from period to period. For further information, refer to the consolidated financial statements and footnotes as set forth in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011.

NOTE 3.         Investments in Affiliated Companies

Investments in affiliated companies represent investments in and loans to domestic and foreign companies and joint ventures that are in businesses similar to those of GATX, such as lease financing and related services for customers operating rail, marine and industrial equipment assets as well as other business activities.

Operating results for all affiliated companies, assuming GATX held a 100% interest, would be (in millions):

	Three Months Ended September 30				Nine Months Ended September 30
	2012		2011		2012		2011
Revenues	$	163.2	$	165.9	$	506.4	$	502.0
Pre-tax income reported by affiliates		40.2		6.7		41.6		89.2

NOTE 4.         Variable Interest Entities

GATX evaluates whether an entity is a variable interest entity (“VIE”) based on the sufficiency of the entity’s equity and whether the equity holders have the characteristics of a controlling financial interest. To determine if it is the primary beneficiary of a VIE, GATX assesses whether it has the power to direct the activities that most significantly impact the economic performance of the VIE and the obligation to absorb losses or the right to receive benefits that may be significant to the VIE. These determinations are both qualitative and quantitative in nature and require certain judgments and assumptions about the VIE’s forecasted financial performance and the volatility inherent in those forecasted results. GATX evaluates new investments for VIE determination and regularly reviews all existing entities for any events that may result in an entity becoming a VIE or GATX becoming the primary beneficiary of an existing VIE.

GATX is the primary beneficiary of a consolidated VIE related to a structured lease financing for a portfolio of railcars because it has the power to direct the significant activities of the VIE through its ownership of the equity interests in the transaction. The risks associated with this VIE are substantially similar to those of GATX’s wholly-owned railcar leasing activities.

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

The carrying amounts of assets and liabilities of the VIE were (in millions):

	September 30 2012		December 31 2011
Operating assets, net of accumulated depreciation (a)	$	99.7	$	104.3
Nonrecourse debt		37.5		45.2

(a) All operating assets are pledged as collateral on the nonrecourse debt.

GATX is also involved with other entities determined to be VIEs of which GATX is not the primary beneficiary. These VIEs are primarily leveraged leases and certain investments in railcar and equipment leasing affiliates that have been financed through a mix of equity investments and third party lending arrangements. GATX determined that it is not the primary beneficiary of these VIEs because it does not have the power to direct the activities that most significantly impact the entities’ economic performance. For certain investments in affiliates determined to be VIEs, GATX concluded that power was shared among the affiliate partners based on the terms of the relevant joint venture agreements, which require approval of all partners for significant decisions involving the VIE.

The carrying amounts and maximum exposure to loss with respect to VIEs that GATX does not consolidate were (in millions):

	September 30, 2012				December 31, 2011

(a) Designated as hedges

(b) Not designated as hedges

Available for sale equity securities are valued based on quoted prices on an active exchange. Warrants are valued based on the fair value of the underlying securities. Derivatives are valued using a pricing model with inputs (such as yield curves and credit spreads) that are observable in the market or can be derived principally from or corroborated by observable market data.

Derivative instruments

Fair Value Hedges — GATX uses interest rate swaps to convert fixed rate debt to floating rate debt and to manage the fixed to floating rate mix of its debt obligations. For fair value hedges, changes in fair value of both the derivative and the hedged item are recognized in earnings as interest expense. As of September 30, 2012 and December 31, 2011, GATX had three instruments outstanding with an aggregate notional amount of $350.0 million for each period. As of September 30, 2012, these derivatives had maturities ranging from 2012-2015.

Cash Flow Hedges — GATX uses interest rate swaps to convert floating rate debt to fixed rate debt and to manage the fixed to floating rate mix of its debt obligations. GATX also uses interest rate swaps and Treasury rate locks to hedge its exposure to interest rate risk on existing and anticipated transactions. As of September 30, 2012 and December 31, 2011, GATX had 12 instruments outstanding with an aggregate notional amount of $99.1 million and 11 instruments outstanding with an aggregated notional amount of $73.4 million, respectively. As of September 30, 2012, these derivatives had maturities ranging from 2012-2019. Within the next 12 months, GATX expects to reclassify $6.9 million ($4.4 million after-tax) of net losses on previously terminated derivatives from accumulated unrealized loss on derivative instruments to earnings. Amounts are reclassified when interest and operating lease expense attributable to the hedged transactions affect earnings.

Non-designated Derivatives — GATX does not hold or issue derivative financial instruments for purposes other than hedging, although certain derivatives are not designated as accounting hedges. Changes in the fair value of these derivatives are recognized in earnings immediately.

Certain of GATX’s derivative instruments contain credit risk provisions that could require GATX to make immediate payment on net liability positions in the event that GATX defaulted on certain outstanding debt obligations. The aggregate fair value of all derivative instruments with credit risk related contingent features that are in a liability position as of September 30, 2012, was $1.3 million. GATX is not required to post any collateral on its derivative instruments and does not expect the credit risk provisions to be triggered.

In the event that a counterparty fails to meet the terms of the interest rate swap agreement or a foreign exchange contract, GATX’s exposure is limited to the fair value of the swap if in GATX’s favor. GATX manages the credit risk of counterparties by transacting only with institutions that the Company considers financially sound and by avoiding concentrations of risk with a single counterparty. GATX considers the risk of non-performance by a counterparty to be remote.

The income statement and other comprehensive income impacts of GATX’s derivative instruments were (in millions):

Derivative Designation	Location of Gain (Loss) Recognized	Three Months  Ended September 30						Nine Months  Ended September 30
		2012			2011			2012			2011
Fair value hedges (a)	Interest expense	$	(1.3	)	$	0.4		$	(3.9	)	$	(0.3	)

Cash flow hedges	Interest expense (effective portion reclassified from accumulated unrealized loss on derivative instruments)		(1.1	)		(2.1	)		(4.1	)		(6.0	)
Cash flow hedges	Operating lease expense (effective portion reclassified from accumulated unrealized loss on derivative instruments)		(0.4	)		(0.4	)		(1.1	)		(1.2	)
Non-designated	Other expense		(2.1	)		2.6			(0.6	)		2.3

(a) Equally offsetting the amount recognized in interest expense was the fair value adjustment relating to the underlying debt.

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. The fair values of investment funds (which are accounted for under the cost method) are based on the best information available and may include quoted investment fund values. The fair values of loans and fixed and floating rate debt were estimated based on discounted cash flow analyses using interest rates currently offered for loans with similar terms to borrowers of similar credit quality. The inputs used in estimating each of these fair values are significant observable inputs and therefore are classified in Level 2 of the fair value hierarchy.

The following table sets forth the carrying amounts and fair values of GATX’s other financial instruments as of (in millions):

	September 30, 2012				December 31, 2011
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Assets
Investment funds	$	2.5	$	5.8	$	2.7	$	7.4

Nonrecourse debt		133.3		142.2		149.4		159.3

NOTE 6.         Commercial Commitments

In connection with certain investments or transactions, GATX has entered into various commercial commitments, such as guarantees and standby letters of credit, which could potentially require performance in the event of demands by third parties. Similar to GATX’s balance sheet investments, these guarantees expose GATX to credit, market and equipment risk; accordingly, GATX evaluates its commitments and other contingent obligations using techniques similar to those used to evaluate funded transactions.

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

The following table shows GATX’s commercial commitments as of (in millions):

	September 30		December 31
	2012		2011
Affiliate guarantees	$	42.0	$	42.0
Asset residual value guarantees		35.3		33.9
Lease payment guarantees		42.4		47.0
Performance bonds		1.3		1.3
Standby letters of credit		9.6		9.8
Total commercial commitments (a)	$	130.6	$	134.0

(a) At September 30, 2012 and December 31, 2011, the carrying values of liabilities on the balance sheet for commercial commitments were $6.7 million and $6.4 million, respectively. The expirations of these commitments range from 2013 to 2022. GATX is not aware of any event that would require it to satisfy any of these commitments.

Affiliate guarantees generally represent GATX’s guarantee of repayment of a portion of the financing utilized by the affiliate to acquire or lease-in assets. These guarantees are in lieu of making direct equity investments in the affiliate and reduce the affiliate’s financing costs. GATX is not aware of any event that would require it to satisfy these guarantees and expects the affiliates to generate sufficient cash flow to satisfy their financing obligations.

Asset residual value guarantees represent GATX’s commitment to third parties that an asset or group of assets will be worth a specified amount at the end of a lease term. GATX earns an initial fee for providing these asset value guarantees, which is amortized into income over the guarantee period. Upon disposition of the assets, GATX receives a share of any proceeds in excess of the amount guaranteed. Such residual sharing gains are recorded in asset remarketing income. If, at the end of the lease term, the net realizable value of the asset is less than the guaranteed amount, any liability resulting from GATX’s performance pursuant to the residual value guarantee will be reduced by the value realized from disposition of the asset. Asset residual value guarantees include those related to assets of affiliated companies.

Lease payment guarantees represent GATX’s guarantee of third-party lease payments to financial institutions. Any liability resulting from GATX’s performance pursuant to these guarantees will be reduced by the value realized from the underlying asset or group of assets.

GATX and its subsidiaries are also parties to standby letters of credit and performance bonds primarily related to workers’ compensation and general liability insurance coverages. No material claims have been made against these obligations. At September 30, 2012, GATX does not expect any material losses to result from these off balance sheet instruments since performance is not anticipated to be required.

NOTE 7.         Share-Based Compensation

In the first nine months of 2012, GATX granted 350,200 stock appreciation rights (“SARs”), 63,380 restricted stock units, 76,780 performance shares and 15,420 phantom stock units. For the three and nine months ended September 30, 2012, total share-based compensation expense was $3.0 million and $9.1 million, respectively, and related tax benefits were $1.1 million and $3.4 million, respectively. For the three and nine months ended September 30, 2011, total share-based compensation expense was $2.0 million and $6.9 million, respectively, and related tax benefits were $0.8 million and $2.6 million, respectively.

NOTE 8.         Income Taxes

GATX’s effective tax rate was 20% for the nine months ended September 30, 2012, compared to 25% for the nine months ended September 30, 2011. GATX’s effective tax rate in any period is driven by the mix of pre-tax income, including share of affiliates’ earnings, among domestic and foreign jurisdictions which are taxed at different rates. The effective rate for both the current and prior periods reflects the impact of $20.9 million of losses and $11.0 million of gains, respectively, related to certain interest rate swaps at GATX’s European Rail affiliate, AAE Cargo A.G. (“AAE”), which were taxed at the Swiss statutory rate of approximately 10%. Additionally, in the current year, tax benefits of $15.5 million were recognized in connection with the close of a federal tax audit, a $4.6 million deferred tax benefit was recognized in connection with a reduction in the statutory tax rates of the United Kingdom and a $0.7 million deferred tax expense was recognized in connection with an increase in the statutory tax rates of Canada. In the prior year, a $4.1 million deferred tax benefit was recognized in connection with a reduction in the statutory tax rates of the United Kingdom. Excluding the effect of the AAE interest rate swaps and tax adjustments from each period, the effective tax rates for each of the first nine months of 2012 and 2011 was 31%.

As of September 30, 2012, GATX’s gross liability for unrecognized tax benefits totaled $4.7 million, which, if fully recognized, would decrease income tax expense by $4.7 million ($3.2 million net of federal tax). Subject to the completion of certain audits or the expiration of the applicable statute of limitations, the Company believes it is reasonably possible that within the next 12 months, unrecognized foreign tax benefits of $0.4 million may be recognized.

NOTE 10.         Earnings Per Share

Basic earnings per share were computed by dividing net income available to common shareholders by the weighted average number of shares of common stock outstanding during each period. Shares issued or reacquired during the period, if applicable, were weighted for the portion of the period that they were outstanding. Diluted earnings per share give effect to potentially dilutive securities, including convertible preferred stock and equity compensation awards.

The following table sets forth the computation of basic and diluted net income per common share (in millions, except per share amounts):

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 its 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 discussion of these matters, please refer to Note 22 to the Company’s consolidated financial statements as set forth in GATX’s Annual Report on Form 10-K for the year ended December 31, 2011. Except as noted below, there have been no material changes or developments in these matters.

Viareggio Derailment

On June 29, 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, Italy. Five tank cars overturned and one of the overturned cars was punctured by a peg or

10

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

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”). On June 28, 2012, the Public Prosecutors of Lucca (“Public Prosecutors”) formally notified GATX Rail Austria and two of its subsidiaries (collectively, “GRA”), as well as several maintenance and supervisory employees (the “Employees”), that they had concluded their investigation of the Viareggio accident and intend to charge GRA and 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 notices were issued to, among others, four Italian Railway companies and eighteen of their employees. The Public Prosecutor’s report asserts that a crack in one of the tank car’s axles broke, causing the derailment and resulting in a tank car rupture and release of LPG, after the car hit an obstacle on the side of the track placed there by the Italian Railway. The report alleges that the crack was detectible 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 Company believes that GRA and its Employees acted diligently and properly with respect to applicable legal and industry standards and will present numerous scientific and technical defenses to the Public Prosecutor’s report in the forthcoming proceedings. With respect to claims for personal injuries and property damages, the Company and its subsidiaries maintain insurance for such losses, and the Company’s insurers are working cooperatively with the insurer for the Italian Railway to adjust and settle these claims. These joint settlement efforts have resolved the majority of asserted civil damage claims related to the accident, and joint efforts to resolve the remaining civil claims are ongoing. In addition to settling civil claims, the Company’s insurers have been providing reimbursement for legal defense costs, including the costs of criminal defense. Recently, one of the Company’s eleven insurers notified the Company that, with respect to its layer of coverage, it will not reimburse the costs of criminal defense, and the Company is engaged in insurance coverage discussions with that insurer to attempt resolution of the issue. The Company cannot predict the outcome of those discussions or the amount of criminal defense costs that ultimately may not be reimbursed by that insurer. Additionally, the Company cannot predict the outcome of the foregoing legal proceedings or what other legal proceedings, if any, may be initiated against GRA or its personnel, and, therefore, cannot reasonably estimate the amount or range of loss (including criminal defense costs) that may ultimately be incurred in connection with this accident. Accordingly, the Company has not established any accruals with respect to this matter.

Litigation Accruals

The Company has recorded accruals totaling $1.9 million at September 30, 2012, for losses related to those litigation matters that the Company believes to be probable and for which an amount of loss can be reasonably estimated. However, the Company cannot determine a reasonable estimate of the maximum possible loss or range of loss for these matters given that they are at various stages of the litigation process and each case is subject to the inherent uncertainties of litigation (such as the strength of the Company’s legal defenses and the availability of insurance recovery). Although the maximum amount of liability that may ultimately result from any of these matters cannot be predicted with absolute certainty, management expects that none of the matters for which the Company has recorded an accrual, when ultimately resolved, will have a material adverse effect on GATX’s consolidated financial position or liquidity. It is possible, however, that the ultimate resolution of one or more of these matters could have a material adverse effect on the Company’s results of operations in a particular quarter or year if such resolution results in liability that materially exceeds the accrued amount.

In addition, other litigation matters are pending for which the Company has not recorded any accruals because the Company’s potential liability for those matters is not probable or cannot be reasonably estimated based on currently available information. For those matters where the Company has not recorded an accrual but a loss is reasonably possible, the Company cannot determine a reasonable estimate of the maximum possible loss or range of loss for these matters given that they are at various stages of the litigation process and each case is subject to the inherent uncertainties of litigation (such as the strength of the Company’s legal defenses and the availability of insurance recovery). Although the maximum amount of liability that may ultimately result from any of these matters cannot be predicted with absolute certainty, management expects that none of the matters for which the Company has not recorded an accrual, when ultimately resolved, will have a material adverse effect on GATX’s consolidated financial position or liquidity. It is possible, however, that the ultimate resolution of one or more of these matters could have a material adverse effect on the Company’s results of operations in a particular quarter or year if such resolution results in a significant liability for the Company.

Environmental

The Company’s operations are subject to extensive federal, state and local environmental regulations. GATX’s operating procedures include practices to protect the environment from the risks inherent in full service railcar leasing, which involves maintaining railcars used by customers to transport chemicals and other hazardous materials. Additionally, some of GATX’s real estate holdings, including previously owned properties, are or have been used for industrial or transportation-related purposes or leased to commercial or industrial companies whose activities might have resulted in discharges on the property. As a result, GATX is subject to

11

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

environmental cleanup and enforcement actions. In particular, the federal Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), also known as the Superfund law, as well as similar state laws, impose joint and several liability for cleanup and enforcement costs on current and former owners and operators of a site without regard to fault or the legality of the original conduct. If there are other potentially responsible parties (“PRPs”), GATX generally contributes to the cleanup of these sites through cost-sharing agreements with terms that vary from site to site. Costs are typically allocated based on the relative volumetric contribution of material, the period of time the site was owned or operated, and/or the portion of the site owned or operated by each PRP. GATX has been notified that it is a PRP, among many PRPs, for study and cleanup costs at three Superfund sites for which investigation and remediation payments have yet to be determined.

At the time a potential environmental issue is identified, initial accruals for environmental liability are established when such liability is probable and a reasonable estimate of the associated costs can be made. Costs are estimated based on the type and level of investigation and/or remediation activities that the Company’s internal environmental staff (and where appropriate, independent consultants) have determined to be necessary to comply with applicable laws and regulations. Activities include surveys and environmental studies of potentially contaminated sites as well as costs for remediation and restoration of sites determined to be contaminated. In addition, GATX has provided indemnities for potential environmental liabilities to buyers of divested companies. In these instances, accruals are based on the scope and duration of the respective indemnities together with the extent of known contamination. Estimates are periodically reviewed and adjusted as required to reflect additional information about facility or site characteristics or changes in regulatory requirements. GATX conducts a quarterly environmental contingency analysis, which considers a combination of factors including independent consulting reports, site visits, legal reviews, analysis of the likelihood of participation in and the ability of other PRPs to pay for cleanup, and historical trend analyses. GATX does not believe that a liability exists for known environmental risks beyond what has been provided for in its environmental accrual.

GATX is involved in administrative and judicial proceedings and other voluntary and mandatory cleanup efforts at 17 sites, including the Superfund sites, at which it is contributing to the cost of performing the study or cleanup, or both, of alleged environmental contamination. As of September 30, 2012, GATX has recorded accruals of $15.9 million for remediation and restoration costs that the Company believes to be probable and for which the amount of loss can be reasonably estimated. These amounts are included in other liabilities on GATX’s balance sheet. GATX’s environmental liabilities are not discounted.

The Company did not materially change its methodology for identifying and calculating environmental liabilities in the last three years. Currently, no known trends, demands, commitments, events or uncertainties exist that are reasonably likely to occur and materially affect the methodology or assumptions described above.

The recorded accruals represent the Company’s best estimate of all costs for remediation and restoration of affected sites, without reduction for anticipated recoveries from third parties, and include both asserted and unasserted claims. However, the Company is unable to provide a reasonable estimate of the maximum potential loss associated with these sites because cleanup costs cannot be predicted with certainty. Various factors beyond the Company’s control can impact the amount of loss the Company will ultimately incur with respect to these sites, including the extent of corrective actions that may be required; evolving environmental laws and regulations; advances in environmental technology, the extent of other parties’ participation in cleanup efforts; developments in periodic environmental analyses related to sites determined to be contaminated, and developments in environmental surveys and studies of potentially contaminated sites. As a result, future charges associated with these sites could have a significant effect on results of operations in a particular quarter or year if the costs materially exceed the accrued amount as individual site studies and remediation and restoration efforts proceed. However, management believes it is unlikely that the ultimate cost to GATX for any of these sites, either individually or in the aggregate, will have a material adverse effect on its financial position or liquidity.

NOTE 12.        Financial Data of Business Segments

GATX leases, operates, manages and remarkets long-lived, widely-used assets primarily in the rail and marine markets. GATX also invests in joint ventures that complement existing business activities. Headquartered in Chicago, Illinois, GATX has three financial reporting segments: Rail, American Steamship Company (“ASC”) and Portfolio Management.

Rail is principally engaged in leasing tank and freight railcars and locomotives. Rail provides railcars primarily pursuant to full-service leases, under which it maintains the railcars, and pays ad valorem taxes and insurance. Rail also offers net leases for railcars and most of its locomotives, in which case the lessee is responsible for maintenance, insurance and taxes.

ASC owns and operates the largest fleet of U.S. flagged self-unloading vessels on the Great Lakes, providing waterborne transportation of dry bulk commodities for a range of industrial customers.

Portfolio Management focuses on maximizing the value of its existing portfolio of wholly-owned and managed assets, which includes identifying opportunities to remarket certain assets. Portfolio Management also seeks to maximize value from its joint ventures and to selectively invest in domestic marine and container related assets.

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 and GATX’s share of affiliates’ earnings attributable to the segments as well as ownership and operating costs that management believes are directly associated with the maintenance or operation of the revenue earning assets. Operating costs include maintenance costs, marine operating costs and other operating costs such as litigation, asset impairment charges, provisions for losses, environmental costs and asset storage costs. Segment profit excludes selling, general and administrative expenses, income taxes and certain other amounts not allocated to the segments.

GATX allocates debt balances and related interest expense to each segment based upon a pre-determined fixed recourse leverage level expressed as a ratio of recourse debt (including off balance sheet debt) to equity. The leverage levels for Rail, ASC and Portfolio Management are set at 4:1, 1.5:1 and 3:1, respectively. Management believes that by utilizing this leverage and interest expense allocation methodology, each operating segment’s financial performance reflects appropriate risk-adjusted borrowing costs.

Business Overview

This “Management’s Discussion and Analysis of Financial Condition and Results of Operations” is based on financial data derived from the financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and certain other financial data that is 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.

GATX Corporation leases, operates, manages and remarkets long-lived, widely-used assets primarily in the rail and marine markets. GATX also invests in affiliates that complement existing business activities. Headquartered in Chicago, Illinois, GATX has three financial reporting segments: Rail, American Steamship Company (“ASC”) and Portfolio Management.

Operating results for the nine months ended September 30, 2012 are not necessarily indicative of the results that may be achieved for the entire year ending December 31, 2012. For further information, refer to GATX’s Annual Report on Form 10-K for the year ended December 31, 2011.

DISCUSSION OF OPERATING RESULTS

Net income was $107.6 million for the first nine months of 2012 compared to net income of $79.2 million for the first nine months of 2011. Results for the first nine months of 2012 and 2011 include benefits from Tax Adjustments and Other Items of $0.7 million and $13.9 million, respectively. Net income was $53.8 million for the third quarter of 2012 compared to net income of $32.9 million for the third quarter of 2011. Results for the third quarter of 2012 and 2011 include benefits from Tax Adjustments and Other Items of $18.2 million and $1.3 million, respectively. Details of the Tax Adjustments and Other Items can be found under Non-GAAP Financial Measures at the end of this Item 2.

Total investment volume was $523.4 million for the first nine months of 2012 compared to $460.1 million for the first nine months of 2011.

Segment 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 and GATX’s share of affiliates’ earnings attributable to the segments as well as ownership and operating costs that management believes are directly associated with the maintenance or operation of the revenue earning assets. Operating costs include maintenance costs, marine operating costs, and other operating costs such as litigation, asset impairment charges, provisions for losses, environmental costs and asset storage costs. Segment profit excludes selling, general and administrative expenses, income taxes and certain other amounts not allocated to the segments. These amounts are discussed below in Other.

GATX allocates debt balances and related interest expense to each segment based upon a pre-determined fixed recourse leverage level expressed as a ratio of recourse debt (including off balance sheet debt) to equity. The leverage levels for Rail, ASC and Portfolio Management are set at 4:1, 1.5:1 and 3:1, respectively. Management believes that by utilizing this leverage and interest expense allocation methodology, each operating segment’s financial performance reflects appropriate risk-adjusted borrowing costs.

Rail

In the third quarter of 2012, lease rate pricing and demand for tank railcars remained strong. Rail’s utilization in North America was 98.2%, compared to 98.3% at the end of the second quarter and 98.2% at September 30, 2011. The average lease renewal rate on cars in the GATX Lease Price Index (the “LPI”, see definition below) increased 26.4% from the weighted average expiring lease rate, compared to increases of 23.9% for the second quarter of 2012 and 9.6% for the third quarter of 2011.

Rail entered 2012 with leases on approximately 20,000 railcars in North America scheduled to expire during the year, of which approximately 3,700 remained at the end of the third quarter. The majority of year-to-date expirations were renewed with existing customers. In the current strong lease rate environment, as evidenced by the LPI, Rail is highly focused on lengthening lease terms. Lease terms on renewals for cars in the LPI averaged 59 months in the current quarter, consistent with the prior quarter and up from 49 months in the third quarter of 2011. While utilization is high for most railcar types, demand across freight car types is inconsistent, with coal cars particularly weak. Leases on approximately 200 coal cars are scheduled to expire during the remainder of 2012, a portion of which are unlikely to be renewed.

In Europe, Rail has experienced modest improvements in lease rate pricing and has increased its wholly-owned tank car fleet through investments in new railcars. At the end of the third quarter of 2012, fleet utilization was 96.6% compared to 96.3% at the end of the second quarter and 96.0% at September 30, 2011. Demand for tank cars serving the petroleum markets is solid; however, demand for railcars serving the chemical markets has softened. GATX’s European Rail affiliate, AAE Cargo A.G. (“AAE”), which serves freight car markets, is experiencing relatively stable operating results; however, fleet utilization remains much lower than historical norms due to ongoing weakness in the European economy.

During the first nine months of 2012, Rail’s investment volume was $443.9 million, compared to $290.1 million in 2011. Year-to-date, Rail has acquired approximately 4,300 railcars, including railcars delivering under a five-year supply agreement. Also, during the second quarter, GATX entered the Indian railcar leasing market with an agreement to purchase newly manufactured railcars, which are expected to deliver and be placed on lease beginning in the fourth quarter.

GATX Lease Price Index

The LPI is an internally generated business indicator that measures general lease rate pricing on renewals within GATX’s North American rail fleet. The index reflects the weighted average lease rate for a select group of railcar types that GATX believes to be representative of its overall North American fleet. The average renewal lease rate change reflects the percentage change between the weighted average renewal lease rate and the weighted average expiring lease rate for railcars in the LPI. The average renewal term reflects the weighted average renewal lease term in months for railcars in the LPI.

Comparison of the First Nine Months of 2012 to the First Nine Months of 2011

Segment Profit

Rail’s segment profit for the first nine months of 2012 and 2011 reflects losses of $20.9 million and gains of $11.0 million respectively, related to certain interest rate swaps at AAE. Excluding these items from each period, Rail’s segment profit increased $32.3 million, primarily due to higher lease and asset remarketing income, higher affiliate earnings and lower maintenance costs, partially offset by the unfavorable remeasurement of an embedded foreign currency derivative, lower scrapping gains and the unfavorable foreign exchange effects of a stronger U.S. dollar.

AAE holds multiple interest rate swaps intended to hedge interest rate risk associated with existing and forecasted floating rate debt issuances. Some of these swaps do not qualify for hedge accounting and as a result, changes in their fair values are recognized currently in income. The unrealized gains and losses were primarily driven by changes in the underlying benchmark interest rates. AAE’s earnings may be impacted by future gains or losses associated with these swaps. Unrealized losses in 2012 were $7.4 million and unrealized gains in 2011 were $11.0 million. Additionally, in the second quarter of 2012, AAE refinanced a portion of its debt and terminated an associated swap at a loss. GATX’s portion of the loss was $13.5 million, which was included in share of affiliates’ earnings.

Gross Income

Lease income in North America increased $20.5 million, primarily due to higher lease rates in the current year. In Europe, a $2.2 million decrease in lease income was driven primarily by the foreign exchange rate effects of a stronger U.S. dollar, partially offset by higher lease rates and an average of approximately 650 more railcars on lease. Asset remarketing income increased $7.1 million, primarily due to more assets sold in the current year. Other income was $6.5 million lower, primarily due to lower scrapping gains resulting from lower scrap steel rates. Affiliates’ earnings decreased $25.6 million from the prior year. Excluding the impact of the interest rate swaps at AAE from each period, affiliates’ earnings increased $6.3 million, primarily due to higher affiliate operating income, which included lower depreciation expense at AAE of $4.1 million due to a change in railcar depreciation policy enacted in the third quarter of 2012 (based on a re-evaluation of the underlying assumptions) that extended depreciable lives and increased estimated salvage values. The change in policy is expected to benefit AAE’s pre-tax income by an additional $2.0 million in the fourth quarter.

Ownership Costs

Ownership costs were $1.6 million higher than the prior year, primarily due to higher debt and asset balances from acquisitions of railcars, partially offset by the foreign exchange effects of a stronger U.S. dollar.

Other Costs and Expenses

In North America, maintenance costs decreased by $9.7 million, largely due to fewer service events resulting from high lease renewal success. In Europe, maintenance costs were $4.7 million lower, primarily due to the foreign exchange effects of a stronger U.S. dollar.

Other costs were $5.6 million higher than the prior year, primarily due to the unfavorable current year impact from the remeasurement of an embedded foreign currency derivative (related to certain non-functional currency lease contracts).

Comparison of the Third Quarter 2012 to the Third Quarter 2011

Segment Profit

Rail’s segment profit for the third quarter of 2012 and 2011 reflects unrealized losses of $2.1 million and $3.1 million, respectively, related to the interest rate swaps at AAE. Excluding these losses from each period, Rail’s segment profit decreased $0.5 million, primarily due to the unfavorable impact from the remeasurement of an embedded foreign currency derivative, lower scrapping gains and the unfavorable foreign exchange effects of a stronger U.S. dollar, partially offset by higher lease and affiliate income.

22

Gross Income

Lease income in North America increased $10.0 million, primarily due to higher lease rates. In Europe, a $1.3 million decrease in lease income was driven primarily by the foreign exchange effects of a stronger U.S. dollar, partially offset by an average of approximately 600 more railcars on lease at higher lease rates. Asset remarketing income decreased $1.4 million, primarily due to fewer assets sold in the current year. Other income was $4.7 million lower, primarily due to lower scrapping gains resulting from fewer railcars scrapped at lower scrap steel rates. Affiliates’ earnings were $6.3 million higher than the prior year. Excluding the impact of the interest rate swaps at AAE from each period, affiliates’ earnings were $5.3 million higher in the current year, primarily due to the change in depreciation policy at AAE.

Ownership Costs

Ownership costs were $3.1 million higher than the prior year, primarily due to higher debt and asset balances from acquisitions of railcars, partially offset by the foreign exchange effects of a stronger U.S. dollar.

Other Costs and Expenses

In North America, maintenance costs increased $0.8 million, largely due to higher railroad repairs. In Europe, maintenance costs were $1.7 million lower, primarily due to the foreign exchange effects of a stronger U.S. dollar.

Other costs were $6.2 million higher than the prior year, primarily due to the unfavorable current year impact from the remeasurement of an embedded foreign currency derivative.

ASC

Steel production increased in 2012, which drove strong customer demand for iron ore. During the first nine months of 2012, ASC carried 20.9 million net tons of freight compared to 18.6 million net tons in the prior year period. During the third quarter of 2011, the licensed crew members represented by the American Maritime Officers (AMO) declared a strike, which resulted in lower shipping volumes and higher operating costs. During the second quarter of 2012, ASC took delivery of and placed into service a newly constructed articulated tug-barge (“ATB”). This vessel is expected to bring added flexibility to ASC’s fleet. ASC ended the third quarter operating 14 vessels, consistent with the prior year quarter.

Components of ASC’s operating results are outlined below (in millions):

Comparison of the First Nine Months of 2012 to the First Nine Months of 2011

Segment Profit

ASC’s segment profit for the first nine months of 2012 was $11.4 million higher than the prior year, primarily due to higher iron ore freight volumes and the absence of the negative impact of a labor work stoppage in the prior year.

Gross Income

Gross income increased $27.0 million, primarily due to higher iron ore freight volumes and rates and higher fuel surcharges, which offset higher fuel costs.

Ownership Costs

Ownership costs were $2.4 million higher than the prior year, primarily due to lease expense related to the ATB.

Other Costs and Expenses

Maintenance costs were $2.6 million higher than the prior year, primarily due to increased repairs in the current year. Marine operating expenses including fuel costs, increased $10.0 million, primarily due to more vessel operating days in the current year, partially offset by the absence of costs related to the work stoppage in the prior year. Other costs in 2012 primarily related to reserves and settlements for ongoing litigation matters.

Comparison of the Third Quarter of 2012 to the Third Quarter of 2011

Segment Profit

ASC’s segment profit for the third quarter of 2012 was $4.7 million higher than the prior year, primarily due to the absence of the negative impact of a labor work stoppage in the prior year.

Gross Income

Gross income increased $8.9 million, primarily due to higher freight volumes and rates and higher fuel surcharges, which offset higher fuel costs.

Ownership Costs

Ownership costs were $1.5 million higher than the prior year, primarily due to lease expense related to the ATB.

Other Costs and Expenses

Maintenance costs increased $1.0 million, primarily due to increased repairs in the current year. Marine operating expenses including fuel costs, increased $0.8 million, primarily due to more vessel operating days in the current year, partially offset by the absence of costs related to the work stoppage in the prior year. Other costs in 2012 primarily related to reserves and settlements for ongoing litigation matters.

Portfolio Management

Portfolio Management’s total asset base, including off balance sheet assets, was $815.1 million at September 30, 2012, compared to $846.6 million at December 31, 2011, and $864.8 million at September 30, 2011. Investment volume was $62.8 million in the first nine months of 2012 compared to $151.4 million in the prior year period. Investments in 2012 primarily consisted of $24.3 million in new and existing affiliates and $36.6 million in barges and equipment. The Rolls Royce affiliates continued to produce strong operating results while the marine markets remain generally weak for both wholly-owned and affiliate vessels.

(a) Includes off balance sheet assets

Comparison of the First Nine Months of 2012 to the First Nine Months of 2011

Segment Profit

Portfolio Management’s segment profit for the first nine months of 2012 was $20.6 million higher than the prior year, primarily due to higher affiliate earnings and higher asset remarketing income.

Gross Income

Lease income was $4.5 million higher than the prior year, primarily due to income from six vessels acquired from an affiliate in late 2011. Asset remarketing income increased $3.9 million primarily due to higher equipment sales in the current year. Affiliates’ earnings were $15.0 million higher than the prior year, primarily due to higher affiliate asset remarketing income in the current year and the absences of a prior year unfavorable adjustment attributable to an accounting change for residual value guarantees and prior year losses from the dissolution of an affiliate.

Ownership Costs

Ownership costs were slightly higher than the prior year as higher depreciation expense related to the six acquired vessels was largely offset by lower interest expense driven by lower interest rates.

Other Costs and Expenses

Operating costs increased $7.3 million, primarily due to operating expenses related to the six acquired vessels. Other costs decreased $6.0 million, primarily due to the reversal of a provision for losses upon the sale of a non-performing leveraged lease investment and the favorable impact of current year warrant remeasurements.

25

Comparison of the Third Quarter of 2012 to the Third Quarter of 2011

Segment Profit

Portfolio Management’s segment profit for the third quarter of 2012 was $3.5 million higher than the prior year, primarily due to higher affiliate earnings, partially offset by lower asset remarketing income.

Gross Income

Lease income was $1.2 million higher than the prior year, primarily due to income from six vessels acquired from an affiliate in late 2011. Asset remarketing income decreased $7.1 million primarily due to lower equipment sales in the current quarter. Affiliates’ earnings increased $11.0 million, primarily due to higher affiliate asset remarketing income and the absence of losses from the dissolution of an affiliate in the prior year.

Ownership Costs

Ownership costs were comparable to the prior year, as higher depreciation expense related to the six acquired vessels was largely offset by lower interest expense driven by a lower average debt balance and lower interest rates.

Other Costs and Expenses

Other costs and expenses increased $1.2 million, primarily due to operating expenses related to the six acquired vessels, partially offset by lower operating costs for pooled barges.

Other

Other is comprised of selling, general and administrative expenses (“SG&A”), unallocated interest expense and miscellaneous income and expense not directly associated with the reporting segments and eliminations.

Components of Other are outlined below (in millions):

	Three Months Ended September 30					Nine Months Ended September 30
	2012			2011		2012			2011
Selling, general and administrative expenses	$	38.6		$	38.5	$	115.6		$	112.3
Unallocated interest expense, net		1.8			0.8		4.0			3.1
Other income and expense, including eliminations		(0.3	)		—		(0.9	)		(0.4	)
Income taxes		(2.2	)		10.8		26.3			26.0

SG&A in 2012 was $3.3 million and $0.1 million higher for the first nine months and third quarter, respectively, compared to the prior year. Each of the increases was primarily due to higher compensation and post-employment benefits expenses. Largely offsetting the increased expenses in the current quarter were lower facilities and outside services expenses. Unallocated interest expense (the difference between external interest expense and amounts allocated to the reporting segments in accordance with assigned leverage targets) in any period is affected by the Company’s consolidated leverage level as well as the timing of debt issuances and segment investments.

26

Income Taxes

GATX’s effective tax rate was 20% for the nine months ended September 30, 2012, compared to 25% for the nine months ended September 30, 2011. GATX’s effective tax rate in any period is driven by the mix of pre-tax income, including share of affiliates’ earnings, among domestic and foreign jurisdictions which are taxed at different rates. The effective rate for both the current and prior periods reflects the impact of $20.9 million of losses and $11.0 million of gains, respectively, related to certain interest rate swaps at AAE, which were taxed at the Swiss statutory rate of approximately 10%. Additionally, in the current year, tax benefits of $15.5 million were recognized in connection with the close of a federal tax audit, a $4.6 million deferred tax benefit was recognized in connection with a reduction in the statutory tax rates of the United Kingdom and a $0.7 million deferred tax expense was recognized in connection with an increase in the statutory tax rates of Canada. In the prior year, a $4.1 million deferred tax benefit was recognized in connection with a reduction in the statutory tax rates of the United Kingdom. Excluding the effect of the AAE interest rate swaps and tax adjustments from each period, the effective tax rates for each of the first nine months of 2012 and 2011 was 31%.

Cash Flow and Liquidity

GATX generates a significant amount of cash from its operating activities and proceeds from its investment portfolio. GATX also accesses domestic and international capital markets through the issuance of secured and unsecured debt and commercial paper, and borrowings against committed revolving credit lines. These sources of cash, along with available cash balances, are used to service GATX’s debt, lease and dividend obligations, and fund portfolio investments and capital additions. Cash from operations and commercial paper issuances are the primary sources of cash used to fund daily operations.

Cash flows from operations and portfolio proceeds are impacted by changes in working capital and the timing of asset dispositions. As a result, cash flow components may vary materially from quarter to quarter and year to year. As of September 30, 2012, GATX had unrestricted cash balances of $430.6 million. Subsequent to the quarter end, GATX repaid $300.0 million of debt and $85.0 million of commercial paper.

The following table sets forth GATX’s principal sources and uses of cash for the nine months ended September 30 (in millions):

	2012			2011
Principal sources of cash
Net cash provided by operating activities	$	224.6		$	188.9
Portfolio proceeds		260.2			108.9
Other asset sales		22.5			31.5
Proceeds from sale-leaseback		71.3			—
Proceeds from issuance of debt, commercial paper and credit facilities		501.1			555.0
	$	1,079.7		$	884.3
Principal uses of cash

Dividends		(43.6	)		(42.3	)
	$	(905.8	)	$	(859.1	)

Net cash provided by operating activities for the first nine months of 2012 was $224.6 million, an increase of $35.7 million from the prior year. The increase was primarily driven by higher lease and marine income, higher dividends from affiliates, lower maintenance expenses and other changes in working capital. The increase was partially offset by higher incentive compensation payments, and income and value added tax payments in the current year compared to refunds received in the prior year.

Portfolio proceeds for the first nine months of 2012 of $260.2 million increased by $151.3 million from the prior year, primarily due to higher proceeds from sales of leased equipment. Proceeds in 2012 primarily included $133.5 million from sale of operating assets and $82.5 million from the sale of leverage lease investments. Proceeds from other asset sales (primarily scrapping of railcars) of $22.5 million for the first nine months of 2012 decreased by $9.0 million from the prior year. In addition, a sale-leaseback financing was completed for 788 railcars and net proceeds of $71.3 million in the third quarter of 2012.

27

Portfolio investments and capital additions primarily consist of purchases of operating assets, investments in affiliates, loans and capitalized asset improvements. In the first nine months of 2012, Rail acquired approximately 3,400 railcars in North America and 900 railcars in Europe, compared to approximately 2,300 total railcars for the same period of 2011. Portfolio Management investments in 2012 primarily consisted of $24.3 million in new and existing affiliates and $36.6 million in equipment.

Proceeds from the issuance of debt for the first nine months of 2012 were $501.1 million (net of hedges and debt issuance costs). Debt repayments of $334.5 million for the first nine months of 2012 consisted of scheduled debt maturities and repayment of short-term debt.

GATX has a $560 million senior unsecured revolving credit facility that expires in May 2015. As of September 30, 2012, availability under this facility was $415.4 million, with $135.0 million of commercial paper outstanding and $9.6 million of letters of credit issued, both of which are backed by the facility.

Restrictive Covenants

GATX’s $560 million revolving credit facility contains various restrictive covenants, including requirements to maintain a minimum fixed charge coverage ratio and an asset coverage test. Certain of GATX’s bank term loans have the same financial covenants as the $560 million facility.

The indentures for GATX’s public debt also contain various restrictive covenants, including limitation on liens provisions that limit the amount of additional secured indebtedness that GATX may incur. Additionally, certain exceptions to the covenants permit GATX to incur an unlimited amount of purchase money and nonrecourse indebtedness.

The loan agreements for certain of GATX’s wholly-owned European Rail subsidiaries (collectively, “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 these subsidiaries to repay loans to certain related parties (including GATX) and to pay dividends to GATX. The covenants relating to loans and dividends effectively limit the ability of GRE to transfer funds to GATX.

GATX does not anticipate any covenant violations nor does it anticipate that any of these covenants will restrict its operations or its ability to procure additional financing. At September 30, 2012, GATX was in compliance with all covenants and conditions of its credit agreements.

Credit Ratings

The availability of GATX’s funding options may be affected by certain factors, including the global capital market environment and outlook as well as GATX’s financial performance. GATX’s access to capital markets at competitive rates is dependent on its credit rating and ratings outlook, as determined by rating agencies such as Standard & Poor’s (“S&P”) and Moody’s Investor Service (“Moody’s”). As of September 30, 2012, GATX’s long term unsecured debt was rated BBB by S&P and Baa2 by Moody’s. GATX’s ratings outlook from both agencies was stable. GATX’s short-term unsecured debt was rated A-2 by S&P and P-2 by Moody’s.

Critical Accounting Policies

There have been no changes to GATX’s critical accounting policies during the nine months ending September 30, 2012; refer to GATX’s Annual Report on Form 10-K for the year ended December 31, 2011, for a summary of GATX’s policies.

Non-GAAP Financial Measures

This report includes certain financial performance measures computed using non-GAAP components as defined by the SEC. GATX has provided a reconciliation of those non-GAAP components to the most directly comparable GAAP components. Financial measures disclosed in this report are meant to provide additional information and insight into the historical operating results and financial position of the Company. Management uses these measures in analyzing GATX’s financial performance from period to period and in making compensation decisions. These measures are not in accordance with, or a substitute for, GAAP and may be different from, or inconsistent with, non-GAAP financial measures used by other companies.

GATX presents the financial measures of return on equity and net income that exclude the effect of Tax Adjustments and Other Items. Management believes that excluding these items facilitates a more meaningful comparison of financial performance between years and provides transparency into the operating results of GATX’s business. In addition, GATX discloses total on and off balance sheet assets because a significant portion of GATX’s rail fleet has been financed through sale-leasebacks that are accounted for as operating leases and the assets are not recorded on the balance sheet. Management believes this information provides investors with a better representation of the assets deployed in GATX’s businesses.

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 Tax Adjustments and Other Items — Net income excluding certain items that GATX believes are not necessarily related to its ongoing business activities.

• Off Balance Sheet Assets — Assets, primarily railcars, which are financed with operating leases and therefore not recorded on the balance sheet. GATX estimates 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 as reported on the balance sheet.

• Total On and Off Balance Sheet Assets — The total of on balance sheet assets and off balance sheet assets.

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

• Return on Equity Excluding Tax Adjustments and Other Items — Net income excluding tax adjustments and other items divided by average shareholders’ equity.

Variable Interest Entities

Variable Interest Entities

NOTE 4.         Variable Interest Entities

GATX evaluates whether an entity is a variable interest entity (“VIE”) based on the sufficiency of the entity’s equity and whether the equity holders have the characteristics of a controlling financial interest. To determine if it is the primary beneficiary of a VIE, GATX assesses whether it has the power to direct the activities that most significantly impact the economic performance of the VIE and the obligation to absorb losses or the right to receive benefits that may be significant to the VIE. These determinations are both qualitative and quantitative in nature and require certain judgments and assumptions about the VIE’s forecasted financial performance and the volatility inherent in those forecasted results. GATX evaluates new investments for VIE determination and regularly reviews all existing entities for any events that may result in an entity becoming a VIE or GATX becoming the primary beneficiary of an existing VIE.

GATX is the primary beneficiary of a consolidated VIE related to a structured lease financing for a portfolio of railcars because it has the power to direct the significant activities of the VIE through its ownership of the equity interests in the transaction. The risks associated with this VIE are substantially similar to those of GATX’s wholly-owned railcar leasing activities.

The carrying amounts of assets and liabilities of the VIE were (in millions):

	September 30 2012		December 31 2011
Operating assets, net of accumulated depreciation (a)	$	99.7	$	104.3
Nonrecourse debt		37.5		45.2

(a) All operating assets are pledged as collateral on the nonrecourse debt.

GATX is also involved with other entities determined to be VIEs of which GATX is not the primary beneficiary. These VIEs are primarily leveraged leases and certain investments in railcar and equipment leasing affiliates that have been financed through a mix of equity investments and third party lending arrangements. GATX determined that it is not the primary beneficiary of these VIEs because it does not have the power to direct the activities that most significantly impact the entities’ economic performance. For certain investments in affiliates determined to be VIEs, GATX concluded that power was shared among the affiliate partners based on the terms of the relevant joint venture agreements, which require approval of all partners for significant decisions involving the VIE.

The carrying amounts and maximum exposure to loss with respect to VIEs that GATX does not consolidate were (in millions):

	September 30, 2012				December 31, 2011

Basis of Presentation

NOTE 2.         Basis of Presentation

The accompanying unaudited consolidated financial statements of GATX Corporation and its subsidiaries have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by these accounting principles for complete financial statements. In the opinion of management, all adjustments (which are of a normal recurring nature) considered necessary for a fair presentation have been included. Operating results for the nine months ended September 30, 2012, are not necessarily indicative of the results that may be achieved for the entire year ending December 31, 2012. In particular, ASC’s fleet is generally inactive for a significant portion of the first quarter of each year due to the winter conditions on the Great Lakes. In addition, the timing of asset remarketing income is dependent, in part, on market conditions and, therefore, does not occur evenly from period to period. For further information, refer to the consolidated financial statements and footnotes as set forth in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011.

Financial Data of Business Segments

NOTE 12.        Financial Data of Business Segments

GATX leases, operates, manages and remarkets long-lived, widely-used assets primarily in the rail and marine markets. GATX also invests in joint ventures that complement existing business activities. Headquartered in Chicago, Illinois, GATX has three financial reporting segments: Rail, American Steamship Company (“ASC”) and Portfolio Management.

Rail is principally engaged in leasing tank and freight railcars and locomotives. Rail provides railcars primarily pursuant to full-service leases, under which it maintains the railcars, and pays ad valorem taxes and insurance. Rail also offers net leases for railcars and most of its locomotives, in which case the lessee is responsible for maintenance, insurance and taxes.

ASC owns and operates the largest fleet of U.S. flagged self-unloading vessels on the Great Lakes, providing waterborne transportation of dry bulk commodities for a range of industrial customers.

Portfolio Management focuses on maximizing the value of its existing portfolio of wholly-owned and managed assets, which includes identifying opportunities to remarket certain assets. Portfolio Management also seeks to maximize value from its joint ventures and to selectively invest in domestic marine and container related assets.

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 and GATX’s share of affiliates’ earnings attributable to the segments as well as ownership and operating costs that management believes are directly associated with the maintenance or operation of the revenue earning assets. Operating costs include maintenance costs, marine operating costs and other operating costs such as litigation, asset impairment charges, provisions for losses, environmental costs and asset storage costs. Segment profit excludes selling, general and administrative expenses, income taxes and certain other amounts not allocated to the segments.

GATX allocates debt balances and related interest expense to each segment based upon a pre-determined fixed recourse leverage level expressed as a ratio of recourse debt (including off balance sheet debt) to equity. The leverage levels for Rail, ASC and Portfolio Management are set at 4:1, 1.5:1 and 3:1, respectively. Management believes that by utilizing this leverage and interest expense allocation methodology, each operating segment’s financial performance reflects appropriate risk-adjusted borrowing costs.

The following tables depict the profitability, financial position and capital expenditures of each of GATX’s business segments for the three and nine months ended September 30, 2012 and 2011 (in millions):

Commercial Commitments

NOTE 6.         Commercial Commitments

In connection with certain investments or transactions, GATX has entered into various commercial commitments, such as guarantees and standby letters of credit, which could potentially require performance in the event of demands by third parties. Similar to GATX’s balance sheet investments, these guarantees expose GATX to credit, market and equipment risk; accordingly, GATX evaluates its commitments and other contingent obligations using techniques similar to those used to evaluate funded transactions.

The following table shows GATX’s commercial commitments as of (in millions):

	September 30		December 31
	2012		2011
Affiliate guarantees	$	42.0	$	42.0
Asset residual value guarantees		35.3		33.9
Lease payment guarantees		42.4		47.0
Performance bonds		1.3		1.3
Standby letters of credit		9.6		9.8
Total commercial commitments (a)	$	130.6	$	134.0

(a) At September 30, 2012 and December 31, 2011, the carrying values of liabilities on the balance sheet for commercial commitments were $6.7 million and $6.4 million, respectively. The expirations of these commitments range from 2013 to 2022. GATX is not aware of any event that would require it to satisfy any of these commitments.

Affiliate guarantees generally represent GATX’s guarantee of repayment of a portion of the financing utilized by the affiliate to acquire or lease-in assets. These guarantees are in lieu of making direct equity investments in the affiliate and reduce the affiliate’s financing costs. GATX is not aware of any event that would require it to satisfy these guarantees and expects the affiliates to generate sufficient cash flow to satisfy their financing obligations.

Asset residual value guarantees represent GATX’s commitment to third parties that an asset or group of assets will be worth a specified amount at the end of a lease term. GATX earns an initial fee for providing these asset value guarantees, which is amortized into income over the guarantee period. Upon disposition of the assets, GATX receives a share of any proceeds in excess of the amount guaranteed. Such residual sharing gains are recorded in asset remarketing income. If, at the end of the lease term, the net realizable value of the asset is less than the guaranteed amount, any liability resulting from GATX’s performance pursuant to the residual value guarantee will be reduced by the value realized from disposition of the asset. Asset residual value guarantees include those related to assets of affiliated companies.

Lease payment guarantees represent GATX’s guarantee of third-party lease payments to financial institutions. Any liability resulting from GATX’s performance pursuant to these guarantees will be reduced by the value realized from the underlying asset or group of assets.

GATX and its subsidiaries are also parties to standby letters of credit and performance bonds primarily related to workers’ compensation and general liability insurance coverages. No material claims have been made against these obligations. At September 30, 2012, GATX does not expect any material losses to result from these off balance sheet instruments since performance is not anticipated to be required.

Basic earnings per share were computed by dividing net income available to common shareholders by the weighted average number of shares of common stock outstanding during each period. Shares issued or reacquired during the period, if applicable, were weighted for the portion of the period that they were outstanding. Diluted earnings per share give effect to potentially dilutive securities, including convertible preferred stock and equity compensation awards.

Income Taxes

NOTE 8.         Income Taxes

GATX’s effective tax rate was 20% for the nine months ended September 30, 2012, compared to 25% for the nine months ended September 30, 2011. GATX’s effective tax rate in any period is driven by the mix of pre-tax income, including share of affiliates’ earnings, among domestic and foreign jurisdictions which are taxed at different rates. The effective rate for both the current and prior periods reflects the impact of $20.9 million of losses and $11.0 million of gains, respectively, related to certain interest rate swaps at GATX’s European Rail affiliate, AAE Cargo A.G. (“AAE”), which were taxed at the Swiss statutory rate of approximately 10%. Additionally, in the current year, tax benefits of $15.5 million were recognized in connection with the close of a federal tax audit, a $4.6 million deferred tax benefit was recognized in connection with a reduction in the statutory tax rates of the United Kingdom and a $0.7 million deferred tax expense was recognized in connection with an increase in the statutory tax rates of Canada. In the prior year, a $4.1 million deferred tax benefit was recognized in connection with a reduction in the statutory tax rates of the United Kingdom. Excluding the effect of the AAE interest rate swaps and tax adjustments from each period, the effective tax rates for each of the first nine months of 2012 and 2011 was 31%.

As of September 30, 2012, GATX’s gross liability for unrecognized tax benefits totaled $4.7 million, which, if fully recognized, would decrease income tax expense by $4.7 million ($3.2 million net of federal tax). Subject to the completion of certain audits or the expiration of the applicable statute of limitations, the Company believes it is reasonably possible that within the next 12 months, unrecognized foreign tax benefits of $0.4 million may be recognized.

Legal Proceedings and Other Contingencies

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 its 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 discussion of these matters, please refer to Note 22 to the Company’s consolidated financial statements as set forth in GATX’s Annual Report on Form 10-K for the year ended December 31, 2011. Except as noted below, there have been no material changes or developments in these matters.

Viareggio Derailment

On June 29, 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, 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”). On June 28, 2012, the Public Prosecutors of Lucca (“Public Prosecutors”) formally notified GATX Rail Austria and two of its subsidiaries (collectively, “GRA”), as well as several maintenance and supervisory employees (the “Employees”), that they had concluded their investigation of the Viareggio accident and intend to charge GRA and 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 notices were issued to, among others, four Italian Railway companies and eighteen of their employees. The Public Prosecutor’s report asserts that a crack in one of the tank car’s axles broke, causing the derailment and resulting in a tank car rupture and release of LPG, after the car hit an obstacle on the side of the track placed there by the Italian Railway. The report alleges that the crack was detectible 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 Company believes that GRA and its Employees acted diligently and properly with respect to applicable legal and industry standards and will present numerous scientific and technical defenses to the Public Prosecutor’s report in the forthcoming proceedings. With respect to claims for personal injuries and property damages, the Company and its subsidiaries maintain insurance for such losses, and the Company’s insurers are working cooperatively with the insurer for the Italian Railway to adjust and settle these claims. These joint settlement efforts have resolved the majority of asserted civil damage claims related to the accident, and joint efforts to resolve the remaining civil claims are ongoing. In addition to settling civil claims, the Company’s insurers have been providing reimbursement for legal defense costs, including the costs of criminal defense. Recently, one of the Company’s eleven insurers notified the Company that, with respect to its layer of coverage, it will not reimburse the costs of criminal defense, and the Company is engaged in insurance coverage discussions with that insurer to attempt resolution of the issue. The Company cannot predict the outcome of those discussions or the amount of criminal defense costs that ultimately may not be reimbursed by that insurer. Additionally, the Company cannot predict the outcome of the foregoing legal proceedings or what other legal proceedings, if any, may be initiated against GRA or its personnel, and, therefore, cannot reasonably estimate the amount or range of loss (including criminal defense costs) that may ultimately be incurred in connection with this accident. Accordingly, the Company has not established any accruals with respect to this matter.

Litigation Accruals

The Company has recorded accruals totaling $1.9 million at September 30, 2012, for losses related to those litigation matters that the Company believes to be probable and for which an amount of loss can be reasonably estimated. However, the Company cannot determine a reasonable estimate of the maximum possible loss or range of loss for these matters given that they are at various stages of the litigation process and each case is subject to the inherent uncertainties of litigation (such as the strength of the Company’s legal defenses and the availability of insurance recovery). Although the maximum amount of liability that may ultimately result from any of these matters cannot be predicted with absolute certainty, management expects that none of the matters for which the Company has recorded an accrual, when ultimately resolved, will have a material adverse effect on GATX’s consolidated financial position or liquidity. It is possible, however, that the ultimate resolution of one or more of these matters could have a material adverse effect on the Company’s results of operations in a particular quarter or year if such resolution results in liability that materially exceeds the accrued amount.

In addition, other litigation matters are pending for which the Company has not recorded any accruals because the Company’s potential liability for those matters is not probable or cannot be reasonably estimated based on currently available information. For those matters where the Company has not recorded an accrual but a loss is reasonably possible, the Company cannot determine a reasonable estimate of the maximum possible loss or range of loss for these matters given that they are at various stages of the litigation process and each case is subject to the inherent uncertainties of litigation (such as the strength of the Company’s legal defenses and the availability of insurance recovery). Although the maximum amount of liability that may ultimately result from any of these matters cannot be predicted with absolute certainty, management expects that none of the matters for which the Company has not recorded an accrual, when ultimately resolved, will have a material adverse effect on GATX’s consolidated financial position or liquidity. It is possible, however, that the ultimate resolution of one or more of these matters could have a material adverse effect on the Company’s results of operations in a particular quarter or year if such resolution results in a significant liability for the Company.

Environmental

The Company’s operations are subject to extensive federal, state and local environmental regulations. GATX’s operating procedures include practices to protect the environment from the risks inherent in full service railcar leasing, which involves maintaining railcars used by customers to transport chemicals and other hazardous materials. Additionally, some of GATX’s real estate holdings, including previously owned properties, are or have been used for industrial or transportation-related purposes or leased to commercial or industrial companies whose activities might have resulted in discharges on the property. As a result, GATX is subject to environmental cleanup and enforcement actions. In particular, the federal Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), also known as the Superfund law, as well as similar state laws, impose joint and several liability for cleanup and enforcement costs on current and former owners and operators of a site without regard to fault or the legality of the original conduct. If there are other potentially responsible parties (“PRPs”), GATX generally contributes to the cleanup of these sites through cost-sharing agreements with terms that vary from site to site. Costs are typically allocated based on the relative volumetric contribution of material, the period of time the site was owned or operated, and/or the portion of the site owned or operated by each PRP. GATX has been notified that it is a PRP, among many PRPs, for study and cleanup costs at three Superfund sites for which investigation and remediation payments have yet to be determined.

At the time a potential environmental issue is identified, initial accruals for environmental liability are established when such liability is probable and a reasonable estimate of the associated costs can be made. Costs are estimated based on the type and level of investigation and/or remediation activities that the Company’s internal environmental staff (and where appropriate, independent consultants) have determined to be necessary to comply with applicable laws and regulations. Activities include surveys and environmental studies of potentially contaminated sites as well as costs for remediation and restoration of sites determined to be contaminated. In addition, GATX has provided indemnities for potential environmental liabilities to buyers of divested companies. In these instances, accruals are based on the scope and duration of the respective indemnities together with the extent of known contamination. Estimates are periodically reviewed and adjusted as required to reflect additional information about facility or site characteristics or changes in regulatory requirements. GATX conducts a quarterly environmental contingency analysis, which considers a combination of factors including independent consulting reports, site visits, legal reviews, analysis of the likelihood of participation in and the ability of other PRPs to pay for cleanup, and historical trend analyses. GATX does not believe that a liability exists for known environmental risks beyond what has been provided for in its environmental accrual.

GATX is involved in administrative and judicial proceedings and other voluntary and mandatory cleanup efforts at 17 sites, including the Superfund sites, at which it is contributing to the cost of performing the study or cleanup, or both, of alleged environmental contamination. As of September 30, 2012, GATX has recorded accruals of $15.9 million for remediation and restoration costs that the Company believes to be probable and for which the amount of loss can be reasonably estimated. These amounts are included in other liabilities on GATX’s balance sheet. GATX’s environmental liabilities are not discounted.

The Company did not materially change its methodology for identifying and calculating environmental liabilities in the last three years. Currently, no known trends, demands, commitments, events or uncertainties exist that are reasonably likely to occur and materially affect the methodology or assumptions described above.

The recorded accruals represent the Company’s best estimate of all costs for remediation and restoration of affected sites, without reduction for anticipated recoveries from third parties, and include both asserted and unasserted claims. However, the Company is unable to provide a reasonable estimate of the maximum potential loss associated with these sites because cleanup costs cannot be predicted with certainty. Various factors beyond the Company’s control can impact the amount of loss the Company will ultimately incur with respect to these sites, including the extent of corrective actions that may be required; evolving environmental laws and regulations; advances in environmental technology, the extent of other parties’ participation in cleanup efforts; developments in periodic environmental analyses related to sites determined to be contaminated, and developments in environmental surveys and studies of potentially contaminated sites. As a result, future charges associated with these sites could have a significant effect on results of operations in a particular quarter or year if the costs materially exceed the accrued amount as individual site studies and remediation and restoration efforts proceed. However, management believes it is unlikely that the ultimate cost to GATX for any of these sites, either individually or in the aggregate, will have a material adverse effect on its financial position or liquidity.

(a) Designated as hedges

(b) Not designated as hedges

Available for sale equity securities are valued based on quoted prices on an active exchange. Warrants are valued based on the fair value of the underlying securities. Derivatives are valued using a pricing model with inputs (such as yield curves and credit spreads) that are observable in the market or can be derived principally from or corroborated by observable market data.

Derivative instruments

Fair Value Hedges — GATX uses interest rate swaps to convert fixed rate debt to floating rate debt and to manage the fixed to floating rate mix of its debt obligations. For fair value hedges, changes in fair value of both the derivative and the hedged item are recognized in earnings as interest expense. As of September 30, 2012 and December 31, 2011, GATX had three instruments outstanding with an aggregate notional amount of $350.0 million for each period. As of September 30, 2012, these derivatives had maturities ranging from 2012-2015.

Cash Flow Hedges — GATX uses interest rate swaps to convert floating rate debt to fixed rate debt and to manage the fixed to floating rate mix of its debt obligations. GATX also uses interest rate swaps and Treasury rate locks to hedge its exposure to interest rate risk on existing and anticipated transactions. As of September 30, 2012 and December 31, 2011, GATX had 12 instruments outstanding with an aggregate notional amount of $99.1 million and 11 instruments outstanding with an aggregated notional amount of $73.4 million, respectively. As of September 30, 2012, these derivatives had maturities ranging from 2012-2019. Within the next 12 months, GATX expects to reclassify $6.9 million ($4.4 million after-tax) of net losses on previously terminated derivatives from accumulated unrealized loss on derivative instruments to earnings. Amounts are reclassified when interest and operating lease expense attributable to the hedged transactions affect earnings.

Non-designated Derivatives — GATX does not hold or issue derivative financial instruments for purposes other than hedging, although certain derivatives are not designated as accounting hedges. Changes in the fair value of these derivatives are recognized in earnings immediately.

Certain of GATX’s derivative instruments contain credit risk provisions that could require GATX to make immediate payment on net liability positions in the event that GATX defaulted on certain outstanding debt obligations. The aggregate fair value of all derivative instruments with credit risk related contingent features that are in a liability position as of September 30, 2012, was $1.3 million. GATX is not required to post any collateral on its derivative instruments and does not expect the credit risk provisions to be triggered.

In the event that a counterparty fails to meet the terms of the interest rate swap agreement or a foreign exchange contract, GATX’s exposure is limited to the fair value of the swap if in GATX’s favor. GATX manages the credit risk of counterparties by transacting only with institutions that the Company considers financially sound and by avoiding concentrations of risk with a single counterparty. GATX considers the risk of non-performance by a counterparty to be remote.

Non-designated	Other expense		(2.1	)		2.6			(0.6	)		2.3

(a) Equally offsetting the amount recognized in interest expense was the fair value adjustment relating to the underlying debt.

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. The fair values of investment funds (which are accounted for under the cost method) are based on the best information available and may include quoted investment fund values. The fair values of loans and fixed and floating rate debt were estimated based on discounted cash flow analyses using interest rates currently offered for loans with similar terms to borrowers of similar credit quality. The inputs used in estimating each of these fair values are significant observable inputs and therefore are classified in Level 2 of the fair value hierarchy.
