1.    Description of Business, Basis of Presentation, and Changes in Significant Accounting Policies

Ally Financial Inc. (referred to herein as Ally, we, our, or us) is a leading, independent, diversified financial services firm. Founded in 1919, we are a leading financial services company with more than 95 years of experience providing a broad array of financial products and services, primarily to automotive dealers and retail customers. We operate as a financial holding company (FHC) and a bank holding company (BHC). Our banking subsidiary, Ally Bank, is an indirect, wholly-owned subsidiary of Ally Financial Inc. and a leading franchise in the growing direct (internet, telephone, mobile, and mail) banking market.

Our accounting and reporting policies conform to accounting principles generally accepted in the United States of America (GAAP). Additionally, where applicable, the policies conform to the accounting and reporting guidelines prescribed by bank regulatory authorities. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and that affect income and expenses during the reporting period and related disclosures. In developing the estimates and assumptions, management uses all available evidence; however, actual results could differ because of uncertainties associated with estimating the amounts, timing, and likelihood of possible outcomes.

The Condensed Consolidated Financial Statements at March 31, 2015, and for the three months endedMarch 31, 2015, and 2014, are unaudited but reflect all adjustments that are, in management’s opinion, necessary for the fair presentation of the results for the interim periods presented. All such adjustments are of a normal recurring nature. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements (and the related notes) included in our Annual Report on Form 10-K for the year ended December 31, 2014, as filed on February 27, 2015, with the U.S. Securities and Exchange Commission (SEC).

Significant Accounting Policies

Income Taxes

In calculating the provision for interim income taxes, in accordance with Accounting Standards Codification (ASC) 740, Income Taxes, we apply an estimated annual effective tax rate to year-to-date ordinary income. At the end of each interim period, we estimate the effective tax rate expected to be applicable for the full fiscal year. This method differs from that described in Note 1 to the Consolidated Financial Statements in our 2014 Annual Report on Form 10-K, which describes our annual significant income tax accounting policy and related methodology.

Refer to Note 1 to the Consolidated Financial Statements in our 2014 Annual Report on Form 10-K regarding additional significant accounting policies.

Recently Adopted Accounting Standards

Receivables — Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (ASU 2014-04)

As of January 1, 2015, we adopted ASU 2014-04. The amendments in this ASU clarify the timing for which an entity should reclassify a loan that has been foreclosed or where an in substance repossession has occurred to real estate owned. The guidance requires a reclassification to occur when the entity obtains legal title upon completion of foreclosure or the borrower conveys all interest in the residential real estate property to the entity to satisfy the loan through completion of a deed in lieu of foreclosure or similar legal agreement. In addition, the ASU clarifies that redemption rights of the borrower should be ignored for purposes of determining whether legal title has transferred. We adopted the guidance utilizing a modified retrospective approach. The adoption of this guidance did not have a material effect on our consolidated financial condition or results of operations.

Presentation of Financial Statements and Property, Plant, and Equipment — Reporting Discontinued Operations and Disclosure of Disposals of Components of an Entity (ASU 2014-08)

As of January 1, 2015, we adopted ASU 2014-08. The amendments in this ASU modify the requirements for the reporting of discontinued operations. In order to qualify as a discontinued operation, the disposal of a component of an entity, a group of components, or a business of an entity must represent a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. The ASU further indicates that the timing for recording a discontinued operation is when one of the following occurs: the component, group of components, or business meets the criteria to be classified as held-for-sale; the component, group of components, or business is disposed of by sale; or the component, group of components, or business is disposed of other than by sale (for example abandonment or spinoff). In addition, the ASU also requires additional disclosure items about an entity’s discontinued operations. The amendments were applied prospectively solely to newly identified disposals that qualify as discontinued operations after the effective date. Items previously reported as discontinued operations will maintain their classification based on the prior guidance. The adoption of this guidance did not have a material effect on our consolidated financial condition or results of operations.

Transfers and Servicing — Repurchase-to-Maturity Transactions, Repurchase Financings and Disclosures (ASU 2014-11)

As of January 1, 2015, we adopted ASU 2014-11. The amendments in this ASU change the accounting for repurchase-to-maturity transactions and repurchase financing transactions such that both will be reported as secured borrowings. In addition to the changes to how

10

Notes to Condensed Consolidated Financial Statements (unaudited)

Ally Financial Inc. • Form 10-Q

these transactions are reported, the ASU also includes new disclosure requirements. The amendments are effective for us beginning on January 1, 2015. The amendments were applied to all transactions that fall under the guidance as of the date of adoption with a cumulative effect adjustment recorded on the date of initial adoption. The adoption of this guidance did not have a material effect on our consolidated financial condition or results of operations.

Recently Issued Accounting Standards

Revenue from Contracts with Customers (ASU 2014-09)

In May 2014, the Financial Accounting Standards Board (FASB) issued ASU 2014-09. The purpose of this guidance is to streamline and consolidate existing revenue recognition principles in GAAP and to converge revenue recognition principles with International Financial Reporting Standards (IFRS). The core principle of the amendments is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to receive in exchange for those goods or services. The amendments include a five step process for consideration of the main principle, guidance on the accounting treatment for costs associated with a contract, and disclosure requirements related to the revenue process. The amendments are effective for us beginning on January 1, 2017. The amendments can be applied either through a full retrospective application or retrospectively with a cumulative effect adjustment on the date of initial adoption. Early adoption is prohibited. Management is assessing the impact of the adoption of this guidance.

Consolidation — Amendments to the Consolidation Analysis (ASU 2015-02)

In February 2015, the FASB issued ASU 2015-02. The amendments in this update modify the requirements of consolidation with respect to entities that are or are similar in nature to limited partnerships or are variable interest entities (VIEs). For entities that are or are similar to limited partnerships, the guidance clarifies the evaluation of kick-out rights, removes the presumption that the general partner will consolidate and generally states that such entities will be presumed to be VIEs unless proven otherwise. For VIEs, the guidance modifies the analysis related to the evaluation of servicing fees, excludes servicing fees that are deemed commensurate with the level of service required from the determination of the primary beneficiary and clarifies certain considerations related to the consolidation analysis when performing a related party assessment. The amendments are effective for us on January 1, 2016, with early adoption permitted. The amendments can be applied either through a full retrospective application or on a modified retrospective basis with a cumulative effect adjustment on the date of initial adoption. Management is assessing the impact of the adoption of this guidance.

Imputation of Interest — Simplifying the Presentation of Debt Issuance Costs (ASU 2015-03)

In April 2015, the FASB issued ASU 2015-03. The amendments in this update require that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. Currently debt issuance costs are presented as a deferred charge and are therefore presented as an asset. The recognition and measurement requirements will not change as a result of this guidance. The amendments are effective for us on January 1, 2016, with early adoption permitted. The amendments must be applied with retrospective application, with each balance sheet period presented showing the impacts of applying the guidance. The guidance is not expected to have a material impact to our consolidated financial condition or results of operations.

2.     Discontinued and Held-for-sale Operations

Discontinued Operations

Prior to the adoption of ASU 2014-08, which is to be prospectively applied only to newly identified disposals that qualify as discontinued operations beginning after January 1, 2015, we have classified operations as discontinued when operations and cash flows will be eliminated from our ongoing operations and we do not expect to retain any significant continuing involvement in their operations after the respective sale or disposal transactions. For all periods presented, the operating results for these discontinued operations have been removed from continuing operations and presented separately as discontinued operations, net of tax, in the Condensed Consolidated Statement of Comprehensive Income. The Notes to the Condensed Consolidated Financial Statements have been adjusted to exclude discontinued operations unless otherwise noted.

Select Automotive Finance Operations

During the fourth quarter of 2012, we committed to sell our automotive finance operations in Europe and Latin America to General Motors Financial Company, Inc. (GMF). On the same date, we entered into an agreement with GMF to sell our 40% interest in a motor vehicle finance joint venture in China. During the second quarter of 2013, we completed the sale of our operations in Europe and the majority of Latin America. The transaction included European operations in Germany, the United Kingdom, Italy, Sweden, Switzerland, Austria, Belgium, France and the Netherlands, and Latin America operations in Mexico, Chile, and Colombia. During the fourth quarter of 2013, we completed the sale of our Latin American operations in Brazil.

On January 2, 2015, the sale of our interest in the motor vehicle finance joint venture in China was completed and an after-tax gain of approximately $400 million was recorded. The tax expense included in this gain was reduced by the release of valuation allowance on our capital loss carryforward deferred tax asset that was utilized to offset capital gains stemming from this sale.

Other Operations

Other operations relate to previous discontinued operations for which we continue to have minimal residual costs.

Select Financial Information

Select financial information of discontinued operations is summarized below. The pretax income or loss, including direct costs to transact a sale, includes any impairment recognized to present the operations at the lower-of-cost or fair value. Fair value was based on the estimated sales price, which could differ from the ultimate sales price due to price volatility, changing interest rates, changing foreign-currency rates, and future economic conditions.

The following table presents gross gains and losses realized upon the sales of available-for-sale securities and other-than-temporary impairment.

Certain available-for-sale securities were sold at a loss in 2015 and 2014 as a result of market conditions within these respective periods (e.g., a downgrade in the rating of a debt security), in accordance with our risk management policies and practices. The table below summarizes available-for-sale securities in an unrealized loss position in accumulated other comprehensive income. Based on the methodology that was applied to these securities, we believe that the unrealized losses relate to factors other than credit losses in the current market environment. As of March 31, 2015, we did not have the intent to sell the debt securities with an unrealized loss position in accumulated other comprehensive income, and it is not more likely than not that we will be required to sell these securities before recovery of their amortized cost basis. As of March 31, 2015, we had the ability and intent to hold equity securities with an unrealized loss position in accumulated other comprehensive income, and it is not more likely than not that we will be required to sell these securities before recovery of their amortized cost basis. As a result, we believe that the securities with an unrealized loss position in accumulated other comprehensive income are not considered to be other-than-temporarily impaired at March 31, 2015. Refer to Note 1 to the Consolidated Financial Statements in our 2014 Annual Report on Form 10-K for additional information related to investment securities and our methodology for evaluating potential other-than-temporary impairments.

Troubled Debt Restructurings

Troubled Debt Restructurings (TDRs) are loan modifications where concessions were granted to borrowers experiencing financial difficulties. Numerous initiatives are in place to provide support to our mortgage customers in financial distress, including principal forgiveness, maturity extensions, delinquent interest capitalization, and changes to contractual interest rates. Additionally for automotive loans, we may offer several types of assistance to aid our customers, including extension of the loan maturity date and rewriting the loan terms. Total TDRs recorded at historical cost and reported at carrying value before allowance for loan losses were $557 million and $681 million at March 31, 2015, and December 31, 2014, respectively. The decrease was primarily due to the whole-loan sale of consumer mortgage TDRs. Refer to Note 1 to the Consolidated Financial Statements in our 2014 Annual Report on Form 10-K for additional information.

9.    Securitizations and Variable Interest Entities

We are involved in several types of securitization and financing transactions that utilize special-purpose entities (SPEs). A SPE is an entity that is designed to fulfill a specified limited need of the sponsor. Our principal use of SPEs is to obtain liquidity by securitizing certain of our financial assets and operating lease assets.

The SPEs involved in our securitization and other financing transactions are generally considered VIEs. VIEs are entities that have either a total equity investment at risk that is insufficient to permit the entity to finance its activities without additional subordinated financial support or whose equity investors at risk lack the ability to control the entity's activities.

We provide a wide range of consumer and commercial automotive loans, operating leases, and commercial loans to a diverse customer base. We often securitize these loans (also referred to as financial assets) and leases through the use of securitization entities, which may or may not be consolidated on our Condensed Consolidated Balance Sheet.

There were no sales of financial assets into nonconsolidated securitization and asset-backed financing entities for the three months ended March 31, 2015 and 2014.

We have involvement with various other on-balance sheet, immaterial VIEs. Most of these VIEs are used for additional liquidity whereby we sell certain financial assets into the VIE and issue beneficial interests to third parties for cash. We also provide long-term guarantee contracts to investors in certain nonconsolidated affordable housing entities and have extended a line of credit to provide liquidity and minimize our exposure under these contracts. Since we do not have control over the entities or the power to make decisions, we do not consolidate the entities and our involvement is limited to the guarantee and the line of credit.

We have involvement with various other nonconsolidated affordable housing entities and venture capital funds. We do not consolidate these entities and our involvement is limited to the capital contributed and committed to these funds plus any previously recognized low income housing tax credits.

Refer to Note 10 to the Consolidated Financial Statements in our 2014 Annual Report on Form 10-K for further description of our securitization activities and our involvement with VIEs.

10.     Servicing Activities

Automotive Finance Servicing Activities

We service consumer automotive contracts. Historically, we have sold a portion of our consumer automotive contracts. With respect to contracts we sell, we retain the right to service and earn a servicing fee for our servicing function. Typically, we conclude that the fee we are paid for servicing consumer automotive finance receivables represents adequate compensation, and consequently, we do not recognize a servicing asset or liability. We recognized automotive servicing fee income of $10 million and $9 million during the three months endedMarch 31, 2015 and 2014, respectively.

The following table presents the composition of our short-term borrowings portfolio.

(a) Refer to Note 14 for further details on assets restricted as collateral for payment of the related debt.

We periodically enter into term repurchase agreements, short-term borrowing agreements in which we sell financial instruments to one or more investors while simultaneously committing to repurchase them at a specified future date, at the stated price plus accrued interest. As of March 31, 2015, the financial instruments sold under agreement to repurchase consisted of U.S. Treasury and Federal Agency securities with maturities as follows: $1.7 billion within the next 30 days and $504 million within 31 to 60 days. The primary risk associated with these repurchase agreements is that the counterparty will be unable to perform under the terms of the contract. As the borrower, we are exposed to the excess market value of the securities pledged over the amount borrowed. Daily mark-to-market collateral management is designed to limit this risk to the initial margin. However, should a counterparty declare bankruptcy or become insolvent, we may incur additional delays and costs.

19.    Regulatory Capital and Other Regulatory Matters

As a BHC, we and our wholly-owned state-chartered banking subsidiary, Ally Bank, are subject to capital requirements issued by U.S. banking regulators that require us to maintain risk-based and leverage capital ratios above minimum levels. A risk-based capital ratio is a ratio of a banking organization’s regulatory capital to its risk-weighted assets. A leverage capital ratio is a ratio of a banking organization’s regulatory capital to a measure of assets or exposures that is not risk-weighted. As of January 1, 2015, Ally and Ally Bank became subject to the rules implementing the 2010 Basel III capital framework in the United States (U.S. Basel III), which reflect new and higher capital requirements, capital buffers, and new regulatory capital definitions, deductions and adjustments. Certain aspects of U.S. Basel III, including the new capital buffers and regulatory capital deductions, will be phased in over several years.

Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary action by regulators that, if undertaken, could have a direct material effect on the Condensed Consolidated Financial Statements or the results of operations and financial condition of Ally and Ally Bank. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, we must meet specific capital guidelines that involve quantitative measures of our capital, assets and certain off-balance sheet items. These measures and related classifications, which are used in our risk-based and leverage capital ratios, are also subject to qualitative judgments by the regulators about the components of capital, the risk-weightings of our assets and other exposures, and other factors. The U.S. banking regulators also use these ratios and guidelines as part of the capital planning and stress testing processes. In addition, in order for Ally to maintain its status as a FHC, Ally and its bank subsidiary, Ally Bank, must remain “well-capitalized” and “well-managed,” as defined under applicable law. Effective January 1, 2015, the “well-capitalized” standard for insured depository institutions, such as Ally Bank, was revised to reflect the new and higher capital requirements under U.S. Basel III.

Under U.S. Basel III, Ally must maintain a minimum Common Equity Tier 1 risk-based capital ratio of 4.5%, a minimum Tier 1 risk-based capital ratio of 6%, and a minimum Total risk-based capital ratio of 8%. In addition to these minimum requirements, Ally will also be subject to a Common Equity Tier 1 capital conservation buffer of more than 2.5%, subject to a phase-in period from January 1, 2016 through December 31, 2018. Failure to maintain the full amount of the buffer will result in restrictions on Ally’s ability to make capital distributions, including dividend payment and stock repurchases and redemptions, and to pay discretionary bonuses to executive officers. In addition to these new risk-based capital standards, U.S. Basel III subjects all U.S. banking organizations, including Ally, to a minimum Tier 1 leverage ratio of 4%, the denominator of which takes into account only on-balance sheet assets.

In addition to introducing new capital ratios, U.S. Basel III revises the eligibility criteria for regulatory capital instruments and provides for the phase-out of existing capital instruments that do not satisfy the new criteria. Subject to certain exceptions (e.g., for certain debt or equity issued to the U.S. government under the Emergency Economic Stabilization Act), trust preferred and other “hybrid” securities will be phased out from a banking organization’s Tier 1 capital by January 1, 2016. Also, subject to a phase-in schedule, certain new items will be deducted from Common Equity Tier 1 capital, and certain other deductions from regulatory capital will be modified. Among other things, U.S. Basel III requires significant investments in the common shares of unconsolidated financial institutions, mortgage servicing rights, and

certain deferred tax assets that exceed specified individual and aggregate thresholds to be deducted from Common Equity Tier 1 capital. U.S. Basel III also revises the standardized approach for calculating risk-weighted assets by, among other things, modifying certain risk weights and introducing new methods for calculating risk-weighted assets for certain types of assets and exposures.

Ally is subject to the U.S. Basel III standardized approach for counterparty credit risk. It is not subject to the U.S. Basel III advanced approaches for counterparty credit risk. Ally is currently not subject to the U.S. market risk capital rule, which applies only to banking organizations with significant trading assets and liabilities.

During 2010, Ally, IB Finance Holding Company, LLC (IB Finance), Ally Bank, and the Federal Deposit Insurance Corporation (FDIC) entered into a Capital and Liquidity Maintenance Agreement (CLMA). The effective date of the CLMA was August 24, 2010. The CLMA requires capital at Ally Bank to be maintained at a level such that Ally Bank's leverage ratio is at least 15%. For this purpose, the leverage ratio is determined in accordance with the FDIC's regulations related to capital maintenance.

The following table summarizes our capital ratios under the U.S. Basel III capital framework.

	Under Basel III				Under Basel I
	March 31, 2015 (a)				December 31, 2014 (b)				Required minimum			Well-capitalized minimum

(a) U.S. Basel III became effective for us on January 1, 2015, subject to transitional provisions primarily related to deductions and adjustments impacting Common Equity Tier 1 capital and Tier 1 capital.

(b) Capital ratios as of December 31, 2014 are presented under the U.S. Basel I capital framework.

(c) Previously referred to as Tier 1 Common Equity under the U.S. Basel I capital framework.

(d) U.S. Basel III does not establish standards for determining whether a BHC is "well-capitalized."

(e) Federal regulatory reporting guidelines require the calculation of adjusted quarterly average assets using a daily average methodology.

(f) Ally Bank, in accordance with the CLMA, is required to maintain a Tier 1 leverage ratio of at least 15%.

At March 31, 2015, Ally and Ally Bank were “well-capitalized” and met all capital requirements to which each was subject.

Capital Planning and Stress Tests

As a BHC with $50 billion or more of consolidated assets, Ally is required to conduct periodic internal stress tests, is subject to an annual supervisory stress test conducted by the Board of Governors of the Federal Reserve System (FRB), and must submit an annual capital plan to the FRB. Ally’s capital plan must include a description of all planned capital actions over a nine-quarter planning horizon. The capital plan must also include a discussion of how Ally will maintain capital above the minimum regulatory capital ratios and above a Tier 1 common equity-to-total risk-weighted assets ratio of 5% under baseline, adverse, and severely adverse economic scenarios, and serve as a source of strength to Ally Bank. The FRB must approve Ally's capital plan before Ally may take any capital action. Even with an approved capital plan, Ally must seek the approval of the FRB before making a capital distribution if, among other factors, Ally would not meet its regulatory capital requirements after making the proposed capital distribution.

On January 5, 2015, Ally Financial Inc. submitted the results of its semi-annual stress test and its proposed capital actions to the FRB, and Ally Bank submitted the results of its annual company-run stress test to the FDIC. On March 6, 2015, Ally Financial Inc. and Ally Bank publicly disclosed summary results of the stress test under the most severe scenario in accordance with regulatory requirements. On March 11, 2015, Ally received a non-objection to its capital plan from the FRB, including the proposed capital actions contained in its submission. As a result, we redeemed $1.3 billion in Series G preferred securities in April 2015, and announced a tender offer to purchase up to 13 million shares of our outstanding Series A preferred securities for $26.65 per share.

20.    Derivative Instruments and Hedging Activities

We enter into interest rate, foreign-currency, and equity swaps, futures, forwards, options, and swaptions in connection with our market risk management activities. Derivative instruments are used to manage interest rate risk relating to specific groups of assets and liabilities, including automotive loan assets and debt. We use foreign exchange contracts to mitigate foreign-currency risk associated with foreign-currency-denominated debt, foreign exchange transactions, and our net investment in foreign subsidiaries. In addition, we also enter into equity option contracts to manage our exposure to the equity markets. Our primary objective for utilizing derivative financial instruments is to manage interest rate risk associated with our fixed and variable rate assets and liabilities, foreign exchange risks related to our foreign-currency denominated assets and liabilities, and market risks related to our investment portfolio and certain of our executive share-based compensation plans.

Interest Rate Risk

We monitor our mix of fixed- and variable-rate assets and liabilities. When it is cost-effective to do so, we may enter into interest rate swaps, forwards, futures, options, and swaptions to achieve our desired mix of fixed- and variable-rate assets and liabilities. We execute interest rate swaps, forwards, futures, options, and swaptions to modify our exposure to interest rate risk by converting certain fixed-rate instruments to a variable-rate and certain variable-rate instruments to a fixed-rate. We use a mix of both derivatives that qualify for hedge accounting treatment and economic hedges.

Derivatives qualifying for hedge accounting consist of receive-fixed swaps designated as fair value hedges of specific fixed-rate debt obligations, pay-fixed swaps designated as fair value hedges of specific portfolios of fixed-rate held-for-investment retail automotive loan assets, and pay-fixed swaps designated as cash flow hedges of the expected future cash flows in the form of interest payments on certain outstanding variable-rate borrowings associated with our secured debt.

We also execute economic hedges, which consist of interest rate swaps and interest rate caps held to mitigate interest rate risk associated with our debt portfolio. We also use interest rate swaps to economically hedge our net fixed-versus-variable interest rate exposure. We enter into economic hedges in the form of short-dated, exchange-traded Eurodollar futures to hedge the interest rate exposure of our fixed-rate automotive loans, as well as forwards, options, and swaptions to economically hedge our net fixed-versus-variable interest rate exposure.

Foreign Exchange Risk

We enter into derivative financial instrument contracts to mitigate the risk associated with variability in cash flows related to our various foreign-currency exposures.

We enter into foreign-currency forwards with external counterparties as net investment hedges of foreign exchange exposure on our investments in foreign subsidiaries. However, we have reduced our foreign exchange exposure to net investments in foreign operations through the sales and disposals of discontinued international businesses. Refer to Note 2 for further details on these sales.

Our remaining foreign subsidiaries in wind-down maintain both assets and liabilities in local currencies. These local currencies are generally the subsidiaries' functional currencies for accounting purposes. Foreign-currency-exchange-rate gains and losses arise when the assets or liabilities of our subsidiaries are denominated in currencies that differ from its functional currency. In addition, our equity is impacted by the cumulative translation adjustments resulting from the translation of foreign subsidiary results; this impact is reflected in our accumulated other comprehensive income (loss).

We utilize a cross-currency swap to economically hedge foreign exchange exposure on foreign-currency-denominated debt by converting the funding currency to our functional currency. This swap was entered into concurrent with the debt issuance with the terms of the derivative matching the terms of the underlying debt.

We also enter into foreign currency forwards to economically hedge our foreign denominated debt, our centralized lending program, and foreign-denominated third party loans. The hedge of foreign denominated debt was entered into concurrent with the debt issuance with the terms of the derivative matching the terms of the underlying debt. The centralized lending program manages liquidity for our subsidiary businesses, but as of March 31, 2015, this activity is immaterial. Foreign-currency-denominated loan agreements are executed with our foreign subsidiaries in their local currencies. We evaluate our foreign-currency exposure resulting from intercompany lending and manage our currency risk exposure by entering into foreign-currency derivatives with external counterparties. Our remaining foreign-currency derivatives, such as hedges of foreign-denominated third party loans, are recorded at fair value with changes recorded as income offsetting the gains and losses on the associated foreign-currency transactions.

Market Risk

We enter into equity options to economically hedge our exposure to the equity markets. We purchase options to assume a long position on certain equities and write options to assume a short position.

We have also entered into prepaid equity forward contracts to economically hedge the price risk associated with certain of our executive share-based compensation plans. The prepaid equity forward contracts are hybrid instruments containing an embedded forward contract, which is considered a derivative instrument. The embedded derivative instrument is bifurcated from the host contract and is recorded at fair value with changes in fair value recorded in compensation and benefits expense. The balance of the prepaid component of these equity forward contracts was $62 million as of March 31, 2015, and was recorded within other assets on the Condensed Consolidated Balance Sheet.

Counterparty Credit Risk

Derivative financial instruments contain an element of credit risk if counterparties are unable to meet the terms of the agreements. Credit risk associated with derivative financial instruments is measured as the net replacement cost should the counterparties that owe us under the contract completely fail to perform under the terms of those contracts, assuming no recoveries of underlying collateral as measured by the market value of the derivative financial instrument.

To mitigate the risk of counterparty default, we maintain collateral agreements with certain counterparties. The agreements require both parties to maintain collateral in the event the fair values of the derivative financial instruments meet established thresholds. In the event that either party defaults on the obligation, the secured party may seize the collateral. Generally, our collateral arrangements are bilateral such that we and the counterparty post collateral for the value of our total obligation to each other. Contractual terms provide for standard and customary exchange of collateral based on changes in the market value of the outstanding derivatives. The securing party posts additional collateral when their obligation rises or removes collateral when it falls.

Certain derivative instruments contain provisions that require us to either post additional collateral or immediately settle any outstanding liability balances upon the occurrence of a specified credit risk-related event. If a credit risk-related event had been triggered, the amount of additional collateral required to be posted by us would have been insignificant.

We placed cash and securities collateral totaling $228 million and $236 million at March 31, 2015 and December 31, 2014, respectively, in accounts maintained by counterparties, $18 million of which relates to non-derivative collateral at March 31, 2015 and December 31, 2014. We received cash collateral from counterparties totaling $118 million at March 31, 2015, $13 million of which relates to non-derivative collateral. We received cash collateral from counterparties totaling $71 million at December 31, 2014. The receivables for collateral placed and the payables for collateral received are included on our Condensed Consolidated Balance Sheet in other assets and accrued expenses and other liabilities, respectively. In certain circumstances, we receive or post securities as collateral with counterparties. We do not record such collateral received on our Condensed Consolidated Balance Sheet unless certain conditions are met. At March 31, 2015 and December 31, 2014, we received noncash collateral of $24 million and $15 million, respectively.

Balance Sheet Presentation

The following table summarizes the fair value amounts of derivative instruments reported on our Condensed Consolidated Balance Sheet. The fair value amounts are presented on a gross basis, are segregated by derivatives that are designated and qualifying as hedging instruments or those that are not, and are further segregated by type of contract within those two categories. Notional amounts are reference amounts from which contractual obligations are derived and are not recorded on the balance sheet. In our view, derivative notional is not an accurate measure of our derivative exposure when viewed in isolation from other factors, such as market rate fluctuations and counterparty credit risk.

21.    Income Taxes

We recognized total income tax expense from continuing operations of $103 million during the three months endedMarch 31, 2015, compared to income tax expense of $94 million for the same period in 2014. The increase in income tax expense for the three months endedMarch 31, 2015, compared to the same period in 2014, was driven primarily by a reduction in tax credits.

As of each reporting date, we consider existing evidence, both positive and negative, that could impact our view with regard to future realization of deferred tax assets. We continue to believe it is more likely than not that the benefit for certain foreign tax credits and state net operating loss carryforwards will not be realized. In recognition of this risk, we continue to provide a partial valuation allowance on the deferred tax assets relating to these carryforwards.

It is reasonably possible the unrecognized tax benefits disclosed in our 2014 Annual Report on Form 10-K will decrease by up to $180 million over the next 12 months if certain tax matters ultimately settle with the applicable taxing jurisdiction as anticipated.

22.    Fair Value

Fair Value Measurements

For purposes of this disclosure, fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability (exit price) in the principal or most advantageous market in an orderly transaction between market participants at the measurement date. Fair value is based on the assumptions market participants would use when pricing an asset or liability. Additionally, entities are required to consider all aspects of nonperformance risk, including the entity’s own credit standing, when measuring the fair value of a liability.

GAAP specifies a three-level hierarchy that is used when measuring and disclosing fair value. The fair value hierarchy gives the highest priority to quoted prices available in active markets (i.e., observable inputs) and the lowest priority to data lacking transparency (i.e., unobservable inputs). An instrument’s categorization within the fair value hierarchy is based on the lowest level of significant input to its valuation. The following is a description of the three hierarchy levels.

Level 1 Inputs are quoted prices in active markets for identical assets or liabilities at the measurement date. Additionally, the entity must have the ability to access the active market, and the quoted prices cannot be adjusted by the entity.

Level 2 Inputs are other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices in active markets for similar assets or liabilities; quoted prices in inactive markets for identical or similar assets or liabilities; or inputs that are observable or can be corroborated by observable market data by correlation or other means for substantially the full term of the assets or liabilities.

Level 3 Unobservable inputs are supported by little or no market activity. The unobservable inputs represent management's best assumptions of how market participants would price the assets or liabilities. Generally, Level 3 assets and liabilities are valued using pricing models, discounted cash flow methodologies, or similar techniques that require significant judgment or estimation.

Transfers Transfers into or out of any hierarchy level are recognized at the end of the reporting period in which the transfer occurred. There were no transfers between any levels during the three months endedMarch 31, 2015.

Following are descriptions of the valuation methodologies used to measure material assets and liabilities at fair value and details of the valuation models, key inputs to those models, and significant assumptions utilized.

• Available-for-sale securities — All classes of available-for-sale securities are carried at fair value based on observable market prices, when available. If observable market prices are not available, our valuations are based on internally developed discounted cash flow models (an income approach) that use a market-based discount rate and consider recent market transactions, experience with similar securities, current business conditions, and analysis of the underlying collateral, as available. To estimate cash flows, we are required to utilize various significant assumptions including market observable inputs (e.g., forward interest rates) and internally developed inputs (including prepayment speeds, delinquency levels, and credit losses).

• Automotive loans held-for-sale, net — Our automotive loans held-for-sale are accounted for at the lower-of-cost or fair value. The automotive loans at fair value are presented in the nonrecurring fair value measurement table. We based our valuation of automotive loans held-for-sale on internally developed discounted cash flow models (an income approach) and classified all these loans as Level 3. These valuation models estimate the exit price we expect to receive in the loan’s principal market, which, depending on characteristics of the loans, may be the whole-loan market or the securitization market. Although we utilize and give priority to market observable inputs, such as interest rates and market spreads within these models, we are typically required to utilize internal inputs, such as prepayment speeds (absolute prepayment model, or ABS), gross loss range by loan segment (percentage of receivable balance lost in the event of default), and credit spreads (the risk premium component added to observed benchmark rate to determine the discount rate used in the discounted cash flow model). While numerous controls exist to calibrate, corroborate, and validate these internal inputs, these internal inputs require the use of judgment and can have a significant impact on the determination of the loan’s value. Accordingly, we classified all automotive loans held-for-sale as Level 3.

• Mortgage loans held-for-sale, net — Certain of our mortgage loans held-for-sale are accounted for at fair value because of fair value option elections. Mortgage loans held-for-sale are typically pooled together and sold into certain exit markets depending on underlying attributes of the loan, such as eligibility with the Federal National Mortgage Association (Fannie Mae), the Federal Home Loan Mortgage Corporation (Freddie Mac), or the Government National Mortgage Association (Ginnie Mae) (collectively, the Government-sponsored Enterprises, or GSEs), product type, interest rate, and credit quality. Mortgage loans previously classified as Level 2 were mainly GSE-eligible mortgage loans carried at fair value due to fair value option election, which were valued predominantly using published forward agency prices. It also included any domestic loans where recently negotiated market prices for the loan pool exist with a counterparty (which approximates fair value) or quoted market prices for similar loans are available. These mortgage loans were transferred into Level 3 as of December 31, 2014 based on decreased observability of significant inputs resulting from no longer being an active seller of mortgage loans to GSEs. As a result, they are now valued based on a discounted cash flow basis utilizing cash flow projections from internally developed models that utilized prepayment, default, and discount rate assumptions.

Refer to the section within this note titled Fair Value Option for Financial Assets and Financial Liabilities for further information about the fair value elections.

• Interests retained in financial asset sales — The interests retained are in securitization trusts and deferred purchase prices on the sale of whole-loans. Due to inactivity in the market, valuations are based on internally developed discounted cash flow models (an income approach) that use a market-based discount rate; therefore, we classified these assets as Level 3. The valuation considers recent market transactions, experience with similar assets, current business conditions, and analysis of the underlying collateral, as available. To estimate cash flows, we utilize various significant assumptions, including market observable inputs (e.g., forward interest rates) and internally developed inputs (e.g., prepayment speeds, delinquency levels, and credit losses).

• Derivative instruments — We enter into a variety of derivative financial instruments as part of our risk management strategies. Certain of these derivatives are exchange traded, such as Eurodollar futures, options of Eurodollar futures, and equity options. To determine the fair value of these instruments, we utilize the quoted market prices for the particular derivative contracts; therefore, we classified these contracts as Level 1.

We also execute over-the-counter (OTC) and centrally-cleared derivative contracts, such as interest rate swaps, a cross-currency swap, swaptions, foreign-currency denominated forward contracts, prepaid equity forward contracts, caps, floors, and agency to-be-announced securities. For OTC contracts, we utilize third-party-developed valuation models that are widely accepted in the market to value these OTC derivative contracts. The specific terms of the contract and market observable inputs (such as interest rate forward curves, interpolated volatility assumptions, or equity pricing) are used in the model. We classified these OTC derivative contracts as Level 2 because all significant inputs into these models were market observable. For centrally-cleared contracts, we utilize unadjusted prices obtained from the clearing house as the basis for valuation, and they are also classified as Level 2. During 2014, we began to value our bilateral interest rate swap and interest rate cap portfolio using Overnight Index Swap discount curves. We previously valued this portfolio using London Interbank Offered Rate (LIBOR) discount curves. Because we continued to use a third-party-developed valuation model in which all significant inputs were market observable, these contracts remained classified as Level 2.

Historically, we had a cross-currency swap and interest rate caps accounted for as derivative instruments that were classified as Level 3. However, at March 31, 2015 and December 31, 2014, we did not have any positions classified as Level 3.

We are required to consider all aspects of nonperformance risk, including our own credit standing, when measuring fair value of a liability. We reduce credit risk on the majority of our derivatives by entering into legally enforceable agreements that enable the posting and receiving of collateral associated with the fair value of our derivative positions on an ongoing basis. In the event that we do not enter into legally enforceable agreements that enable the posting and receiving of collateral, we will consider our credit risk and the credit risk of our counterparties in the valuation of derivative instruments through a credit valuation adjustment (CVA), if warranted. The CVA calculation utilizes the credit default swap spreads of the counterparty.

Nonrecurring Fair Value

We may be required to measure certain assets and liabilities at fair value from time to time. These periodic fair value measures typically result from the application of lower-of-cost or fair value accounting or certain impairment measures. These items would constitute nonrecurring fair value measures.

The following table presents quantitative information regarding the significant unobservable inputs used in significant Level 3 assets measured at fair value on a nonrecurring basis.

				Gross loss	0-4.80%
				Credit spread	0.58%

Fair Value Option for Financial Assets

We elected the fair value option for an insignificant amount of conforming and government-insured mortgage loans held-for-sale. We elected the fair value option to mitigate earnings volatility by better matching the accounting for the assets with the related hedges. Our intent in electing fair value measurement was to mitigate a divergence between accounting losses and economic exposure for certain assets and liabilities.

Fair Value of Financial Instruments

The following table presents the carrying and estimated fair value of financial instruments, except for those recorded at fair value on a recurring basis presented in the previous section of this note titled Recurring Fair Value. When possible, we use quoted market prices to determine fair value. Where quoted market prices are not available, the fair value is internally derived based on appropriate valuation methodologies with respect to the amount and timing of future cash flows and estimated discount rates. However, considerable judgment is required in interpreting market data to develop estimates of fair value, so the estimates are not necessarily indicative of the amounts that could be realized or would be paid in a current market exchange. The effect of using different market assumptions or estimation methodologies could be material to the estimated fair values. Fair value information presented herein was based on information available at March 31, 2015 and December 31, 2014.

The following describes the methodologies and assumptions used to determine fair value for the significant classes of financial instruments. In addition to the valuation methods discussed below, we also followed guidelines for determining whether a market was not active and a transaction was not distressed. As such, we assumed the price that would be received in an orderly transaction (including a market-based return) and not in forced liquidation or distressed sale.

• Cash and cash equivalents — Included in cash and cash equivalents are highly liquid investments that are readily convertible to known amounts of cash and which are subject to an insignificant risk of change in value due to interest rate, quoted price, or penalty

on withdrawal. Classified as Level 1 under the fair value hierarchy, cash and cash equivalents generally expose us to limited credit risk and have no stated maturities or have short-term maturities and carry interest rates that approximate market. As such, the carrying value approximates the fair value of these instruments.

• Loans held-for-sale, net — Loans held-for-sale classified as Level 3 include all loans valued using internally developed valuation models because observable market prices were not available. We based our valuation of automotive loans held-for-sale on internally developed discounted cash flow models (an income approach). These valuation models estimate the exit price we expect to receive in the loan’s principal market, which, depending on characteristics of the loans, may be the whole-loan market or the securitization market. Although we utilize and give priority to market observable inputs, such as interest rates and market spreads within these models, we are typically required to utilize internal inputs, such as prepayment speeds (absolute prepayment model, or ABS), gross loss range by loan segment (percentage of receivable balance lost in the event of default), and credit spreads (the risk premium component added to observed benchmark rate to determine the discount rate used in the discounted cash flow model). While numerous controls exist to calibrate, corroborate, and validate these internal inputs, these internal inputs require the use of judgment and can have a significant impact on the determination of the loan’s value. Accordingly, we classified all automotive loans held-for-sale as Level 3. Loans held-for-sale classified as Level 2 as of December 31, 2014 represent mortgage TDR loans valued using quoted prices in active markets for similar assets.

• Finance receivables and loans, net — With the exception of mortgage loans held-for-investment, the fair value of finance receivables and loans was based on discounted future cash flows using applicable spreads to approximate current rates applicable to each category of finance receivables and loans (an income approach using Level 3 inputs). The carrying value of commercial receivables in certain markets and certain automotive and other receivables for which interest rates reset on a short-term basis with applicable market indices are assumed to approximate fair value either because of the short-term nature or because of the interest rate adjustment feature. The fair value of commercial receivables in other markets was based on discounted future cash flows using applicable spreads to approximate current rates applicable to similar assets in those markets.

For consumer mortgage loans, we used valuation methods and assumptions similar to those used for mortgage loans held-for-sale. These valuations consider unique attributes of the loans such as geography, delinquency status, product type, and other factors. Refer to the section above titled Loans held-for-sale, net, for a description of methodologies and assumptions used to determine the fair value of mortgage loans held-for-sale.

• Deposit liabilities — Deposit liabilities represent certain consumer and brokered bank deposits, mortgage escrow deposits, and dealer deposits. The fair value of deposits at Level 3 were estimated by discounting projected cash flows based on discount factors derived from the forward interest rate swap curve.

• Short-term borrowings and Long-term debt — Level 2 debt was valued using quoted market prices for similar instruments, when available, or other means for substantiation with observable inputs. Debt valued using internally derived inputs, such as prepayment speeds and discount rates, was classified as Level 3.

23.    Offsetting Assets and Liabilities

Our qualifying master netting agreements are written, legally enforceable bilateral agreements that (1) create a single legal obligation for all individual transactions covered by the agreement to the non-defaulting entity upon an event of default of the counterparty, including bankruptcy, insolvency, or similar proceeding, and (2) provide the non-defaulting entity the right to accelerate, terminate, and close-out on a net basis all transactions under the agreement and to liquidate or set off collateral promptly upon an event of default of the counterparty. In certain instances we have the option to report financial instruments that are subject to a qualifying master netting agreement on a net basis. However, we have elected to report these instruments as gross assets and liabilities on the Condensed Consolidated Balance Sheet.

To further mitigate the risk of counterparty default related to derivative instruments, we maintain collateral agreements with certain counterparties. The agreements require both parties to maintain collateral in the event the fair values of the derivative financial instruments meet established thresholds. In the event that either party defaults on the obligation, the secured party may seize the collateral. Generally, our collateral arrangements are bilateral such that we and the counterparty post collateral for the value of our total obligation to each other. Contractual terms provide for standard and customary exchange of collateral based on changes in the market value of the outstanding derivatives. The securing party posts additional collateral when their obligation rises or removes collateral when it falls, such that the net replacement cost of the non-defaulting party is covered in the event of counterparty default.

24.    Segment and Geographic Information

Operating segments are defined as components of an enterprise that engage in business activity from which revenues are earned and expenses incurred for which discrete financial information is available that is evaluated regularly by our chief operating decision maker in deciding how to allocate resources and in assessing performance.

We report our results of operations on a line-of-business basis through three operating segments: Automotive Finance operations, Insurance operations, and Mortgage operations, with the remaining activity reported in Corporate and Other. The operating segments are determined based on the products and services offered, and reflect the manner in which financial information is currently evaluated by management. The following is a description of each of our reportable operating segments.

Automotive Finance operations— Provides automotive financing services to consumers and automotive dealers. Our automotive financing services include providing retail installment sales financing, loans, and leases; offering term loans to dealers, financing dealer floorplans and other lines of credit to dealers; fleet financing, and vehicle remarketing services.

Insurance operations — Offers both consumer financial and insurance products sold primarily through the automotive dealer channel, and commercial insurance products sold to dealers. As part of our focus on offering dealers a broad range of consumer financial and insurance products, we provide vehicle service contracts, maintenance coverage, and guaranteed automobile protection (GAP) products. We also underwrite selected commercial insurance coverages, which primarily insure dealers' vehicle inventories.

Mortgage operations — Our ongoing Mortgage operations include the management of our held-for-investment and held-for-sale mortgage portfolios.

Corporate and Other primarily consists of Corporate Finance, centralized corporate treasury activities, such as management of the cash and corporate investment securities portfolios, short- and long-term debt, retail and brokered deposit liabilities, derivative instruments, the amortization of the discount associated with debt issuances and bond exchanges, and the residual impacts of our corporate funds-transfer pricing (FTP) and treasury asset liability management (ALM) activities. Corporate and Other also includes certain equity investments, overhead that was previously allocated to operations that have since been sold or classified as discontinued operations, and reclassifications and eliminations between the reportable operating segments.

We utilize an FTP methodology for the majority of our business operations. The FTP methodology assigns charge rates and credit rates to classes of assets and liabilities based on expected duration and the LIBOR swap curve plus an assumed credit spread. Matching duration allocates interest income and interest expense to these reportable segments so their respective results are insulated from interest rate risk. This methodology is consistent with our ALM practices, which includes managing interest rate risk centrally at a corporate level. The net residual impact of the FTP methodology is included within the results of Corporate and Other.

Certain of our senior notes issued by the parent are guaranteed by 100% directly owned subsidiaries of Ally (the Guarantors). As of March 31, 2015, the Guarantors include Ally US LLC and IB Finance, each of which fully and unconditionally guarantee the senior notes on a joint and several basis.

The following financial statements present condensed consolidating financial data for (i) Ally Financial Inc. (on a parent company-only basis); (ii) the Guarantors; (iii) the nonguarantor subsidiaries (all other subsidiaries); and (iv) an elimination column for adjustments to arrive at (v) the information for the parent company, the Guarantors, and nonguarantors on a consolidated basis.

Investments in subsidiaries are accounted for by the parent company and the Guarantors using the equity-method for this presentation. Results of operations of subsidiaries are therefore classified in the parent company’s and Guarantors’ investment in subsidiaries accounts. The elimination entries set forth in the following condensed consolidating financial statements eliminate distributed and undistributed income of subsidiaries, investments in subsidiaries, and intercompany balances and transactions between the parent, the Guarantors, and nonguarantors.

26.    Contingencies and Other Risks

In the normal course of business, we enter into transactions that expose us to varying degrees of risk. For additional information on contingencies and other risks arising from such transactions, refer to Note 30 to the Consolidated Financial Statements in our 2014 Annual Report on Form 10-K.

Legal Proceedings

We are or may be subject to potential liability under various governmental proceedings, claims, and legal actions that are pending or otherwise asserted against us. We are named as defendants in a number of legal actions, and we are involved in governmental proceedings arising in connection with our respective businesses. Some of the pending actions purport to be class actions, and certain legal actions include claims for substantial compensatory and/or punitive damages or claims for indeterminate amounts of damages. We establish reserves for legal claims when payments associated with the claims become probable and the payments can be reasonably estimated. Given the inherent difficulty of predicting the outcome of litigation and regulatory matters, it is generally very difficult to predict what the eventual outcome will be, and when the matter will be resolved. The actual costs of resolving legal claims may be higher or lower than any amounts reserved for the claims.

On the basis of information currently available, advice of counsel, available insurance coverage, and established reserves, it is the opinion of management that the eventual outcome of the current actions against us will not have a material adverse effect on our consolidated financial condition, results of operations, or cash flows. However, it is possible that the ultimate resolution of legal matters, if unfavorable, may be material to our consolidated financial condition, results of operations, or cash flows in a particular period.

Regulatory Matters

Ally and its subsidiaries, including Ally Bank, are or may become involved from time to time in formal and informal reviews, investigations, examinations, proceedings, and information-gathering requests by federal and state government and self-regulatory agencies, including, among others, the U.S. Department of Justice (DOJ), SEC, Consumer Financial Protection Bureau (CFPB), the FRB, the FDIC, the Utah Department of Department of Financial Institutions, and the Federal Trade Commission regarding their respective operations.

Mortgage Matters

We have received subpoenas from the DOJ that include a broad request for documentation and other information relating to residential mortgage-backed securities issued by our former mortgage subsidiary, Residential Capital, LLC and its subsidiaries (ResCap RMBS). In connection with these requests, the DOJ is investigating potential fraud and other potential legal claims related to ResCap RMBS, including its investigation of potential claims under the Financial Institutions Reform, Recovery, and Enforcement Act of 1989. The DOJ is also investigating potential claims under the False Claims Act (FCA) related to representations made by us in connection with investments in Ally made by the United States Department of the Treasury pursuant to the Troubled Asset Relief Program in 2008 and 2009 regarding certain claims against Residential Capital, LLC or its subsidiaries at that time. We are engaged in ongoing discussions with the DOJ with respect to legal and factual aspects of their investigations. Further, at the request of the DOJ, we have entered into an agreement to voluntarily extend the statutes of limitations related to potential FCA claims.

We have separately received subpoenas and document requests from the SEC that include information covering a wide range of mortgage-related matters.

Automotive Subprime Matters

In October 2014 we received a document request from the SEC in connection with its investigation related to subprime automotive finance and related securitization activities. Separately, in December 2014, we received a subpoena from the DOJ requesting similar information. We are currently cooperating with both the SEC and DOJ with respect to these matters.

CFPB

In December 2013, Ally Financial Inc. and Ally Bank entered into Consent Orders issued by the CFPB and the DOJ pertaining to the allegation of disparate impact in the automotive finance business. The Consent Orders require Ally to create a compliance plan addressing, at a minimum, the communication of Ally’s expectations of Equal Credit Opportunity Act compliance to dealers, maintenance of Ally’s existing limits on dealer finance income for contracts acquired by Ally, and monitoring for potential discrimination both at the dealer level and within our portfolio of contracts acquired across all dealers. Ally formed a compliance committee consisting of certain Ally and Ally Bank directors to oversee Ally’s execution of the Consent Orders’ terms. Ally is required to meet certain stipulations under the Consent Orders, including a requirement to make monetary payments when ongoing remediation targets are not attained.

Each of the regulatory matters set forth above may result in material adverse consequences including without limitation, adverse judgments, significant settlements, fines, penalties, injunctions, or other actions.

Other Contingencies

We are subject to potential liability under various other exposures including tax, nonrecourse loans, self-insurance, and other miscellaneous contingencies. We establish reserves for these contingencies when the loss becomes probable and the amount can be reasonably estimated. The actual costs of resolving these items may be substantially higher or lower than the amounts reserved for any one item. Based on information currently available, it is the opinion of management that the eventual outcome of these items will not have a material adverse impact on our results of operations, financial position, or cash flows.

27.    Subsequent Events

Declaration of Quarterly Dividend Payments

Management's Discussion and Analysis

Ally Financial Inc. • Form 10-Q

As of January 1, 2015, Ally and Ally Bank became subject to the rules implementing the 2010 Basel III capital framework in the United States (U.S. Basel III), which reflect new and higher capital requirements, capital buffers, and new regulatory capital definitions, deductions and adjustments. Certain aspects of U.S. Basel III, including the new capital buffers and regulatory capital deductions, will be phased in over several years. To assess our capital adequacy against the full impact of U.S. Basel III, we also present "fully phased-in" information that reflects regulatory capital rules that will take effect as of January 1, 2019. Our redemption on April 10, 2015, of 1,288,300 shares of our outstanding Series G Preferred Stock, with an aggregate liquidation preference of approximately $1.3 billion would have resulted in a fully phased-in Common Equity Tier 1 Capital ratio of 9.47% as of March 31, 2015. Capital ratios as of March 31, 2014 are presented under the U.S. Basel I capital framework. Refer to Note 19 to the Condensed Consolidated Financial Statements for further information. The following table presents selected regulatory capital data.

	Under Basel III						Under Basel I
	Transitional			Fully Phased-in
($ in millions)	March 31, 2015						March 31, 2014
Common Equity Tier 1 capital ratio (a)(b)	10.94		%	10.36		%	9.14		%
Tier 1 capital ratio (c)	13.16		%	13.04		%	12.12		%
Total capital ratio (d)	14.11		%	14.03		%	13.02		%
Tier 1 leverage (to adjusted quarterly average assets) (e)	11.43		%	11.39		%	10.39		%

Risk-weighted assets (f)	$	130,142		$	130,907		$	127,734

(a) Common Equity Tier 1 Capital generally consists of common stock (plus any related surplus and net of any treasury stock), retained earnings, accumulated other comprehensive income, and minority interests in the common equity of consolidated subsidiaries, together subject to certain adjustments and deductions. At March 31, 2014, the capital ratio presented reflects the Tier 1 common ratio, the closest analogue under U.S. Basel I to the Common Equity Tier 1 capital ratio introduced by U.S. Basel III. We consider various measures when evaluating capital utilization and adequacy, including the Common Equity Tier 1 Capital ratio. Because GAAP does not include capital ratio measures, we believe there are no comparable GAAP financial measures to these ratios. Common Equity Tier 1 Capital is not formally defined by GAAP and, therefore, is considered to be a non-GAAP financial measure. We believe the Common Equity Tier 1 Capital is important because we believe analysts and banking regulators may assess our capital adequacy using this ratio. Additionally, presentation of this measure allows readers to compare certain aspects of our capital adequacy on the same basis to other companies in the industry.

(b) Our redemption on April 10, 2015, of 1,288,300 shares of our outstanding Series G Preferred Stock, with an aggregate liquidation preference of approximately $1.3 billion would have resulted in a fully phased-in Common Equity Tier 1 Capital ratio of 9.47% as of March 31, 2015.

(c) Tier 1 capital generally consists of common equity, minority interests, qualifying noncumulative preferred stock, and the fixed rate cumulative preferred stock sold to the U.S. Department of the Treasury (Treasury) under the Troubled Asset Relief Program, less goodwill and other adjustments.

(d) Total capital is the sum of Tier 1 and Tier 2 capital. Tier 2 capital generally consists of preferred stock not qualifying as Tier 1 capital, limited amounts of subordinated debt and the allowance for loan losses, and other adjustments.

(e) Tier 1 leverage equals Tier 1 capital divided by adjusted quarterly average total assets (which reflects adjustments for disallowed goodwill and certain intangible assets).

(f) Risk-weighted assets are defined by regulation and are determined by allocating assets and specified off-balance sheet financial instruments into several broad risk categories.

Overview

Ally Financial Inc. is a leading, independent, diversified financial services firm. Founded in 1919, we are a leading financial services company with more than 95 years of experience providing a broad array of financial products and services, primarily to automotive dealers and retail customers. We operate as a financial holding company (FHC) and a bank holding company (BHC). Our banking subsidiary, Ally Bank, is an indirect, wholly-owned subsidiary of Ally Financial Inc. and a leading franchise in the growing direct (internet, telephone, mobile, and mail) banking market.

Initial Public Offering of Common Stock and Stock Split

In April 2014, we completed an initial public offering (IPO) of 95 million shares of common stock at $25 per share. Proceeds from the offering amounted to $2.4 billion, which were obtained by the U.S. Department of the Treasury (Treasury) as the single selling stockholder. In May 2014, the underwriters on the IPO elected to partially exercise the over-allotment option to purchase an additional 7,245,670 shares of Ally common stock at the IPO price of $25 per share. In connection with the IPO, we effected a 310-for-one stock split on shares of our common stock, $0.01 par value per share. Accordingly, all references in this MD&A and in the Condensed Consolidated Financial Statements to share and per share amounts relating to common stock have been adjusted, on a retroactive basis, to recognize the 310-for-one stock split.

Discontinued Operations

During 2013 and 2012, certain disposal groups met the criteria to be presented as discontinued operations. For all periods presented, the operating results for these operations have been removed from continuing operations. Refer to Note 2 to the Condensed Consolidated Financial Statements for more details. The MD&A has been adjusted to exclude discontinued operations unless otherwise noted.

Primary Lines of Business

Dealer Financial Services, which includes our Automotive Finance and Insurance operations, and Mortgage are our primary lines of business. The following table summarizes the operating results excluding discontinued operations of each line of business. Operating results for each of the lines of business are more fully described in the MD&A sections that follow.

• Our Dealer Financial Services operations offer a wide range of financial services and products to retail automotive consumers and automotive dealerships. Our Dealer Financial Services consist of two separate reportable segments — Automotive Finance and Insurance operations. Our automotive finance services include providing retail installment sales financing, loans, and leases; offering term loans to dealers, financing dealer floorplans and other lines of credit to dealers; fleet financing, and vehicle remarketing services.

Our Insurance operations offer both consumer finance protection and insurance products sold primarily through the automotive dealer channel, and commercial insurance products sold to dealers. As part of our focus on offering dealers a broad range of consumer finance and insurance products, we provide vehicle service contracts (VSC), maintenance coverage, and Guaranteed Automobile Protection (GAP) products. We also underwrite selected commercial insurance coverage, which primarily insures dealers' vehicle inventories.

Management's Discussion and Analysis

Ally Financial Inc. • Form 10-Q

As part of our continued efforts to diversify, our Insurance operations initially launched our new flagship vehicle service contract, Ally Premier Protection, in March 2015. We expect to begin offering this product nationwide for new and used vehicles of virtually all makes and models later in 2015 and continuing through 2016. Ally Premier Protection replaces the General Motors Protection Plan nameplate.

On April 27, 2015, we announced that Mitsubishi Motors North America, Inc. (MMNA) has selected Ally as the preferred provider of leasing and financing in the United States, replacing MMNA's captive finance company, Mitsubishi Motors Credit of America, Inc. (MMCA). The agreement broadens our existing relationship with Mitsubishi, and makes our full suite of products and services available to all Mitsubishi dealers and their customers. We intend to purchase the existing consumer portfolio from MMCA, which includes approximately $750 million in retail financings and leases as of January 31, 2015. In addition, we will begin to provide commercial financing to dealerships with approximately $300 million in floorplan assets that are currently financing through MMCA, with the potential to increase dealership relationships in the future.

On May 1, 2015, we were named as the preferred financing source for Aston Martin and will offer our full suite of automotive financial products and services at Aston Martin’s network of 37 dealerships in the United States.

• Our ongoing Mortgage operations are limited to the management of our held-for-investment and held-for-sale mortgage loan portfolios, and include the execution of bulk purchases of high-quality jumbo mortgage loans originated by third parties. During the first quarter of 2015, we continued to execute bulk purchases of mortgage loans that were originated by third parties. Year-to-date purchases have totaled $654 million. We expect this activity to continue in support of our treasury asset liability management (ALM) activities and diversification. Further, we executed the sale of a portfolio of troubled debt restructured (TDR) loans totaling $614 million of unpaid principal balance during the three months ended March 31, 2015.

• Corporate and Other primarily consists of Corporate Finance, centralized corporate treasury activities, such as management of the cash and corporate investment securities and loan portfolios, short- and long-term debt, retail and brokered deposit liabilities, derivative instruments, the amortization of the discount associated with debt issuances and bond exchanges, and the residual impacts of our corporate funds-transfer pricing (FTP) and treasury ALM activities. Corporate and Other also includes certain equity investments, reclassifications and eliminations between the reportable operating segments, and overhead that was previously allocated to operations that have since been sold or classified as discontinued operations. Corporate Finance provides senior secured commercial-lending products to primarily U.S.-based middle market companies. Effective May 1, 2014, Corporate Finance was aligned under Ally Bank, allowing this business to have a more competitive source of funding.

We earned net income from continuing operations of $179 million for the three months endedMarch 31, 2015, compared to $198 million for the three months endedMarch 31, 2014. Net income from continuing operations for the three months endedMarch 31, 2015 was unfavorably impacted by a higher loss on extinguishment of debt resulting from a debt tender offer in February 2015, and an increase in depreciation expense related to lower lease remarketing gains and higher operating lease asset balances. These items were partially offset by lower funding costs resulting from the maturity and repayment of higher-cost debt and lower original issue discount (OID) amortization expense related to bond maturities and normal monthly amortization, as well as a net gain on the sale of a portfolio of TDR loans at our Mortgage operations, and an increase in income from certain equity method investments.

Total financing revenue and other interest income increased $9 million for the three months endedMarch 31, 2015, compared to the same period in 2014. The increase was primarily due to an increase in consumer financing revenue (combined with interest income on consumer loans held-for-sale) for our Automotive Finance operations as a result of continued origination growth across all retail channels, and an increase in operating lease revenue resulting primarily from higher lease asset balances. The increase was partially offset by a decrease in commercial financing revenue for our Automotive Finance operations primarily due to lower commercial assets and lower yields as a result of a competitive wholesale marketplace, as well as a short-term margin impact resulting from the migration of a portion of our dealer floorplan accounts from Prime to London Interbank Offered Rate (LIBOR) indices.

Total interest expensedecreased14% for the three months endedMarch 31, 2015, compared to the same period in 2014, primarily due to lower funding costs as a result of continued deposit growth, the repayment of higher-cost legacy debt, and a decrease in OID amortization expense and increased operating efficiencies.

Depreciation expense on operating lease assets increased $80 million for the three months endedMarch 31, 2015, compared to the same period in 2014, primarily due to lower lease remarketing gains resulting from lower lifetime depreciation recognized on terminated lease vehicles as a result of higher anticipated proceeds based on recent market conditions, as well as higher lease asset balances.

Management's Discussion and Analysis

Ally Financial Inc. • Form 10-Q

Net gain on mortgage and automotive loans increased $46 million for the three months endedMarch 31, 2015, compared to the same period in 2014, primarily due to the sale of a portfolio of TDR loans at our Mortgage operations.

We incurred a loss on extinguishment of debt of $198 million for the three months endedMarch 31, 2015, compared to $39 million for the same period in 2014. The increase was due to a debt tender offer in February 2015.

Other gain on investments, net, was $55 million for the three months endedMarch 31, 2015, compared to $43 million for the same period in 2014. The increase was primarily due to a decrease in other-than-temporary-impairment recognized on certain equity securities, as well as increased sales of equity investments at our Insurance operations.

Other income, net of losses, increased$30 million for the three months endedMarch 31, 2015, compared to the same period in 2014, primarily due to an increase in income from certain equity method investments.

The provision for loan losses was $116 million for the three months endedMarch 31, 2015, compared to $137 million for the same period in 2014. The decrease was primarily due to continued strong performance of the commercial portfolio, combined with improvement in macroeconomic conditions.

Total noninterest expense decreased $18 million for the three months endedMarch 31, 2015, compared to the same period in 2014. The decrease was primarily due to lower VSC losses for our Insurance operations, as well as the overall streamlining of the company from strategic actions.

We recognized total income tax expense from continuing operations of $103 million for the three months endedMarch 31, 2015, compared to income tax expense of $94 million for the same period in 2014. The increase in income tax expense for the three months endedMarch 31, 2015, compared to the same period in 2014, was driven primarily by a reduction in tax credits.

In calculating the continuing operations provision for income taxes, we apply an estimated annual effective tax rate to year-to-date ordinary income on an interim basis. Refer to Note 1 to the Condensed Consolidated Financial Statements for further details.

Our Automotive Finance operations earned income from continuing operations before income tax expense of $331 million for the three months endedMarch 31, 2015, compared to $339 million for the three months endedMarch 31, 2014. Results for the three months endedMarch 31, 2015 were primarily driven by a decrease in net financing revenue due to lower net lease revenue, primarily resulting from lower lease remarketing gains.

Consumer financing revenue (combined with interest income on consumer loans held-for-sale) increased$25 million for the three months endedMarch 31, 2015, compared to the same period in 2014, primarily due to continued origination growth across all retail channels.

Commercial financing revenue decreased $26 million for the three months endedMarch 31, 2015, compared to the same period in 2014, primarily due to lower commercial assets and lower yields as a result of a competitive wholesale marketplace, as well as a short-term margin impact resulting from the migration of a portion of our dealer floorplan accounts from Prime to LIBOR indices.

Total net operating lease revenue decreased 16% for the three months endedMarch 31, 2015, compared to the same period in 2014. The decrease was primarily due to lower lease remarketing gains resulting from lower lifetime depreciation recognized on terminated lease vehicles as a result of higher anticipated proceeds based on recent market conditions, as well as an increase in depreciation expense due to higher operating lease asset balances. We recognized remarketing gains of $69 million for the three months endedMarch 31, 2015, compared to $109 million for the same period in 2014. These items were partially offset by an increase in operating lease revenue resulting from higher lease asset balances.

Interest expense decreased $45 million for the three months endedMarch 31, 2015, compared to the same period in 2014, primarily due to lower funding costs as a result of an increase in deposits and company-wide liability management actions that include the repayment of high-cost debt.

The provision for loan losses was $127 million for the three months endedMarch 31, 2015, compared to $159 million for the same period in 2014. The decrease was primarily due to continued strong performance of the commercial portfolio, combined with improvement in macroeconomic conditions.

Total consumer automotive financing originations increased $652 million for the three months endedMarch 31, 2015, compared to the same period in 2014. The increase for the three months ended March 31, 2015, was primarily due to continued growth in the Non-GM/Chrysler channel, as well as strong volume in the Chrysler channel. Non-GM/Chrysler volume increased 54% for the three months endedMarch 31, 2015, compared to the same period in 2014, due to continued efforts to expand this business. Chrysler channel volume increased 44% for the three months endedMarch 31, 2015, compared to the same period in 2014. The increase in volume was partially offset, as expected, by lower GM lease and new retail subvented business that resulted from GM's recent decision to provide lease subvention programs for Buick, GMC, Cadillac, and Chevrolet products exclusively through its wholly-owned subsidiary, General Motors Financial Company, Inc. (GMF). As a result of this decision, the trend of lower GM lease origination volume will continue and diminish to a negligible level over the near term. However, GM new retail standard increased 34% for the three months endedMarch 31, 2015, compared to the same period in 2014.

Commercial wholesale financing average volume decreased $295 million during the three months endedMarch 31, 2015, compared to the same period in 2014, primarily due to lower dealer inventories. Wholesale penetration with GM and Chrysler decreased slightly for the three months endedMarch 31, 2015, compared to the same period in 2014, as a result of increased competition in the wholesale marketplace. The decrease in GM new receivables was partially offset by an increase in Non-GM/Chrysler commercial wholesale financing volume.

Combined ratio (b)	85.9		%	87.9		%

(a) Includes gain on investments of $33 million and $29 million for the three months endedMarch 31, 2015 and 2014, respectively; and interest expense of $13 million and $14 million for the three months endedMarch 31, 2015 and 2014, respectively.

(b) Management uses a combined ratio as a primary measure of underwriting profitability. Underwriting profitability is indicated by a combined ratio under 100% and is calculated as the sum of all incurred losses and expenses (excluding interest and income tax expense) divided by the total of premiums and service revenues earned and other fee income.

Our Insurance operations earned income from continuing operations before income tax expense of $78 million for the three months ended March 31, 2015, compared to $74 million for the three months ended March 31, 2014. The increase for the three months ended March 31, 2015, was primarily due to lower VSC losses, partially offset by lower earned premium and service revenue.

Insurance premiums and service revenue earned was $233 million for the three months ended March 31, 2015, compared to $241 million for the same period in 2014. The decrease was due primarily to lower earned revenue on Canadian VSC products, lower earned revenue on maintenance and wear products, and higher dealer participation in reinsurance programs.

Insurance losses and loss adjustment expenses totaled $56 million for the three months ended March 31, 2015, compared to $68 million for the same period in 2014. The decrease was primarily due to lower non-weather-related losses driven by lower loss experience of VSC products, and lower wholesale weather losses. This primarily drove the decrease in the combined ratio to 85.9% during the three months ended March 31 2015, compared to 87.9% for the three months ended March 31, 2014.

Insurance premiums and service revenue written was $239 million for the three months ended March 31, 2015, compared to $244 million for the same period in 2014. The decrease was primarily due to lower wholesale premiums driven by non-renewal of non-strategic policies and lower floorplan balances, as well as higher vehicle service reinsurance participation. The decreases were partially offset by higher premiums from new and used vehicle service contracts.

Cash and Investments

A significant aspect of our Insurance operations is the investment of proceeds from premiums and other revenue sources. We use these investments to satisfy our obligations related to future claims at the time these claims are settled. Our Insurance operations have an Investment Committee, which develops guidelines and strategies for these investments. The guidelines established by this committee reflect our risk tolerance, liquidity requirements, regulatory requirements, and rating agency considerations, among other factors.

Our Mortgage operations earned income from continuing operations before income tax expense of $69 million for the three months endedMarch 31, 2015, compared to $17 million for the three months endedMarch 31, 2014. Results for the three months endedMarch 31, 2015, were favorably impacted by a $66 million net gain on the sale of a portfolio of TDR loans totaling $614 million of unpaid principal balance, partially offset by higher provision for loan losses.

Net financing revenue was $15 million for the three months endedMarch 31, 2015, compared to $14 million for the same period in 2014, primarily due to lower interest expense as a result of lower funding costs.

We recognized a net gain on mortgage loans of $66 million for the three months endedMarch 31, 2015, compared to no such activity in the same period in 2014. The increase was primarily due to the sale of a portfolio of TDR loans totaling $614 million of unpaid principal balance.

The provision for loan losses increased$18 million for the three months endedMarch 31, 2015, compared to the same period in 2014, primarily due to lower reserve releases for the three months endedMarch 31, 2015.

Total noninterest expense decreased21% for the three months endedMarch 31, 2015, compared to the same period in 2014. The decrease was primarily due to the sale of our Document Custody Division during the second quarter of 2014.

(b) The amortization is included as interest on long-term debt on the Condensed Consolidated Statement of Comprehensive Income.

Corporate and Other incurred a loss from continuing operations before income tax expense of $196 million for the three months endedMarch 31, 2015, compared to $138 million for the three months endedMarch 31, 2014. The increase in loss from continuing operations before income tax expense for the three months endedMarch 31, 2015 was primarily due to an increase in loss on the extinguishment of debt resulting from a debt tender offer in February, partially offset by a decrease in interest expense and an increase in income from certain equity method investments. Interest expense decreased primarily as a result of lower funding costs resulting from the maturity and repayment of higher-cost debt, and lower OID amortization expense related to bond maturities and normal monthly amortization. The decrease in interest expense was partially offset by unfavorable derivative activity as a result of changes in rates and their impact on economic hedge positions as well as less amortization of deferred basis adjustments on de-designated hedges for the three months endedMarch 31, 2015 compared to the three months endedMarch 31, 2014.

Corporate and Other also includes the results of Corporate Finance which earned income from continuing operations before income tax expense of $19 million for the three months endedMarch 31, 2015, compared to $10 million for the three months endedMarch 31, 2014. The increase resulted from higher net financing revenue due primarily to asset growth in this business, as well as reserve recapture resulting from repayment of certain nonaccrual loan exposures.

Risk Management

Managing the risk/reward trade-off is a fundamental component of operating our businesses. Our risk management program is overseen by the Board, various risk committees, the executive leadership team, and our associates. The Risk and Compliance Committee of the Board, together with the Board, sets the risk appetite across our company while the risk committees, executive leadership team, and our associates identify and monitor current and emerging risks and manage those risks to be within our risk appetite. Ally's primary types of risk include credit, lease residual, market, operational, insurance/underwriting, and liquidity. For more information on our risk management process, refer to the Risk Management MD&A section of our 2014 Annual Report on Form 10-K.

The risks inherent in our loan and lease exposures are largely driven by changes in the overall economy, used vehicle and housing price levels, unemployment levels, and their impact to our borrowers. The potential financial statement impact of these exposures varies depending on the accounting classification and future expected disposition strategy. We retain the majority of our automotive loans as they complement our core business model, but we do sell loans from time to time on an opportunistic basis. We ultimately manage the associated risks based on the underlying economics of the exposure.

Credit Risk Management

Credit risk is defined as the potential failure to receive payments due from an obligor in accordance with contractual obligations. Therefore, credit risk is a major source of potential economic loss to us. Credit risk is monitored by several groups and functions throughout the organization, including enterprise and line of business committees and the Enterprise Risk Management organization. Together, they oversee the credit decisioning and management processes, and monitor credit risk exposures to ensure they are managed in a safe-and-sound manner and are within our risk appetite. In addition, our Loan Review Group provides an independent assessment of the quality of our credit portfolios and credit risk management practices, and directly reports its findings to the Risk and Compliance Committee of the Board on a regular basis.

To mitigate risk, we have implemented specific policies and practices across all lines of business, utilizing both qualitative and quantitative analyses. This reflects our commitment to maintain an independent and ongoing assessment of credit risk and credit quality. Our policies require an objective and timely assessment of the overall quality of the consumer and commercial loan and lease portfolios. This includes the identification of relevant trends that affect the collectability of the portfolios, segments of the portfolios that are potential problem areas, loans and leases with potential credit weaknesses, and the assessment of the adequacy of internal credit risk policies and procedures to

Management's Discussion and Analysis

monitor compliance with relevant laws and regulations. Our consumer and commercial loan and lease portfolios are subject to regular stress tests that are based on plausible, but unexpected, economic scenarios to ensure that we can weather a severe economic downturn. In addition, we maintain limits and underwriting policies that reflect our risk appetite.

We manage credit risk based on the risk profile of the borrower, the source of repayment, the underlying collateral, and current market conditions. We monitor the credit risk profile of individual borrowers and the aggregate portfolio of borrowers either within a designated geographic region or a particular product or industry segment. We perform ongoing analyses of the consumer automotive, consumer mortgage, and commercial portfolios using a range of indicators to assess the adequacy of the allowance based on historical and current trends. Refer to Note 7 to the Condensed Consolidated Financial Statements for additional information.

Additionally, we utilize numerous collection strategies to mitigate loss and provide ongoing support to customers in financial distress. For automotive loans, we work with customers when they become delinquent on their monthly payment. In lieu of repossessing their vehicle, we may offer several types of assistance to aid our customers based on their willingness and ability to repay their loan. Loss mitigation may include extension of the loan maturity date and rewriting the loan terms. For mortgage loans, as part of our participation in certain governmental programs, we offer mortgage loan modifications to qualified borrowers. Numerous initiatives are in place to provide support to our mortgage customers in financial distress, including principal forgiveness, maturity extensions, delinquent interest capitalization, and changes to contractual interest rates.

Furthermore, we manage our counterparty credit exposure based on the risk profile of the counterparty. Within our policies, we have established standards and requirements for managing counterparty risk exposures in a safe-and-sound manner. Counterparty credit risk is derived from multiple exposure types, including derivatives, securities trading, securities financing transactions, financial futures, cash balances (e.g., due from depository institutions, restricted accounts, and cash equivalents), and investment in debt securities. For more information on derivative counterparty credit risk, refer to Note 20 to the Condensed Consolidated Financial Statements.

During the three months endedMarch 31, 2015, the U.S. economy continued to expand. The labor market recovered further during the period, with nonfarm payrolls increasing and the annual unemployment rate falling to 5.5% at March 31, 2015. Within the U.S. automotive market, new light vehicle sales continued to increase to a 16.6 million annual pace for the three months ended March 31, 2015. We closely monitor macro-economic trends given the nature of our business and the potential economic impacts on our credit risk. We continue to be cautious with the economic outlook given continued weak global economic growth and expected higher interest rates as the Federal Reserve is expected to normalize monetary policy later this year.

On-balance Sheet Portfolio

Our on-balance sheet portfolio includes both finance receivables and loans and loans held-for-sale. At March 31, 2015, this primarily included $91.7 billion of automotive finance receivables and loans and $7.7 billion of mortgage finance receivables and loans. Within our on-balance sheet portfolio, we have elected to account for certain mortgage loans at fair value. Changes in the fair value of loans are classified as gain on mortgage and automotive loans, net, in the Condensed Consolidated Statement of Comprehensive Income. Our ongoing Mortgage operations are limited to the management of our held-for-investment and held-for-sale mortgage loan portfolios. During the first quarter of 2015, we continued to execute bulk purchases of high-quality jumbo mortgage loans originated by third parties. We expect to continue this activity in support of our treasury ALM activities and diversification.

(c) Includes outstanding loans from our Commercial Services Group (CSG) of $5.5 billion and $5.2 billion at March 31, 2015 and December 31, 2014, respectively, and recreational vehicle loans of $1.2 billion at both March 31, 2015 and December 31, 2014.

Total on-balance sheet loans outstanding at March 31, 2015, decreased$535 million to $101.4 billion from December 31, 2014, reflecting a decrease of $1.2 billion in the commercial portfolio, partially offset by an increase of $631 million in the consumer portfolio. The decrease in commercial on-balance sheet loans outstanding was primarily driven by seasonality of dealer inventories. The increase in consumer on-balance sheet loans was primarily driven by automotive originations, which outpaced portfolio runoff and partially offset by a whole-loan sale.

Total TDRs outstanding at March 31, 2015, decreased $534 million from December 31, 2014, primarily due to a sale of consumer mortgage TDR loans from the held-for-sale portfolio. Refer to Note 7 to the Condensed Consolidated Financial Statements for additional information.

Total nonperforming loans at March 31, 2015, decreased$54 million to $599 million from December 31, 2014, reflecting a decrease of $37 million of consumer nonperforming loans and a decrease of $17 million of commercial nonperforming loans. The decrease in total nonperforming loans from December 31, 2014 was driven, in part, by fewer accounts deteriorating into nonperforming status within the consumer mortgage portfolio due to continued improvement in the macroeconomic environment. Nonperforming loans include finance receivables and loans on nonaccrual status when the principal or interest has been delinquent for 90 days or when full collection is determined not to be probable. Refer to Note 1 to the Consolidated Financial Statements included in our 2014 Annual Report on Form 10-K for additional information.

Net charge-offs were $150 million for the three months endedMarch 31, 2015, compared to $133 million for the three months endedMarch 31, 2014. The increase during the three months ended March 31, 2015, was driven primarily by the change in our portfolio composition as we continued the execution of our underwriting strategy to originate consumer automotive assets across a broad risk spectrum and aligned with the growth of the portfolio. Loans held-for-sale are accounted for at the lower-of-cost or fair value and, therefore, we do not record charge-offs.

The Consumer Credit Portfolio and Commercial Credit Portfolio discussions that follow relate to consumer and commercial finance receivables and loans recorded at historical cost. Finance receivables and loans recorded at historical cost have an associated allowance for loan losses. Finance receivables and loans measured at fair value were excluded from these discussions since those exposures are not accounted for within our allowance for loan losses.

Consumer Credit Portfolio

During the three months endedMarch 31, 2015, the credit performance of the consumer portfolio remained strong and reflects the continued execution of our underwriting strategy to originate consumer automotive assets across a broad risk spectrum, including used, nonprime, extended term, Non-GM/Chrysler, and non-subvented finance receivables and loans. For information on our consumer credit risk practices and policies regarding delinquencies, nonperforming status, and charge-offs, refer to Note 1 to the Consolidated Financial Statements included in our 2014 Annual Report on Form 10-K.

Total consumer outstanding finance receivables and loans increased$1.1 billion at March 31, 2015 compared with December 31, 2014. The increase in consumer automotive finance receivables and loans was primarily related to our loan originations, which outpaced portfolio runoff and was partially offset by $1.2 billion of loans originated to the held-for-sale portfolio. The increase in consumer mortgage finance receivables and loans was primarily due to growth in the portfolio due to the execution of bulk loan purchases, partially offset by the continued runoff of legacy mortgage assets.

Total consumer nonperforming finance receivables and loans at March 31, 2015decreased$35 million to $528 million from December 31, 2014. The decrease in nonperforming consumer mortgage finance receivables and loans was primarily due to fewer accounts deteriorating into nonperforming status due to continued improvement in the macroeconomic environment. Nonperforming consumer automotive finance receivables and loans decreased primarily due to seasonality. Refer to Note 7 to the Condensed Consolidated Financial Statements for additional information. Nonperforming consumer finance receivables and loans as a percentage of total outstanding consumer finance receivables and loans were 0.8% and 0.9% at March 31, 2015 and December 31, 2014, respectively.

Consumer automotive loans accruing and past due 30 days or more decreased $467 million to $1.1 billion at March 31, 2015, compared with December 31, 2014, primarily due to seasonality.

Our net charge-offs from total consumer finance receivables and loans were $151 million for the three months endedMarch 31, 2015, compared to $133 million for the three months endedMarch 31, 2014. The increase during the three months ended March 31, 2015, was driven primarily by the change in our portfolio composition as we continued the execution of our underwriting strategy to originate consumer automotive assets across a broad risk spectrum, as well as portfolio growth and the seasoning of accounts now entering their prime loss periods.

The following table summarizes the unpaid principal balance of total consumer loan originations for the periods shown. Total consumer loan originations include loans classified as finance receivables and loans and loans held-for-sale during the period.

Total automotive-originated loans increased$1.7 billion for the three months endedMarch 31, 2015, compared to the same period in 2014. The increase during the three months ended March 31, 2015, was distributed across the consumer automotive portfolio with primarily strong growth in new and used originations within both the Non-GM/Chrysler and Chrysler channels.

The following table shows the percentage of total consumer finance receivables and loans recorded at historical cost reported at carrying value before allowance for loan losses by state concentration. Total automotive loans were $57.4 billion and $56.6 billion at March 31, 2015, and December 31, 2014, respectively. Total mortgage and home equity loans were $7.7 billion and $7.5 billion at March 31, 2015 and December 31, 2014, respectively.

Concentrations in our mortgage portfolio are closely monitored given the volatility of the housing market, with special attention given to states with greater declines in real estate values.

Repossessed and Foreclosed Assets

We classify an asset as repossessed or foreclosed (included in other assets on the Condensed Consolidated Balance Sheet) when physical possession of the collateral is taken. We dispose of the acquired collateral in a timely fashion in accordance with regulatory requirements. For more information on repossessed and foreclosed assets, refer to Note 1 to the Consolidated Financial Statements included in our 2014 Annual Report on Form 10-K.

Repossessed assets in our Automotive Finance operations at March 31, 2015 decreased $4 million to $86 million from December 31, 2014. Foreclosed mortgage assets at March 31, 2015, increased $2 million to $12 million from December 31, 2014.

Commercial Credit Portfolio

During the three months endedMarch 31, 2015, the credit performance of the commercial portfolio remained strong, as nonperforming finance receivables and loans improved and no net charge-offs were realized. For information on our commercial credit risk practices and policies regarding delinquencies, nonperforming status, and charge-offs, refer to Note 1 to the Consolidated Financial Statements included in our 2014 Annual Report on Form 10-K.

(c) Other commercial primarily includes senior secured commercial lending.

Total commercial finance receivables and loans outstanding decreased$1.1 billion from December 31, 2014, to $34.8 billion at March 31, 2015. The commercial and industrial finance receivables and loans outstanding decreased $1.2 billion primarily due to seasonality of dealer inventories. This decrease was partially offset by the increase within Other, representing the Corporate Finance portfolio, as the growth in this portfolio continues in line with our business strategy.

Total commercial nonperforming finance receivables and loans were $65 million at March 31, 2015, reflecting a decrease of $17 million when compared to December 31, 2014. The decrease was primarily driven by the full payoff of a nonperforming account and no additional accounts deteriorating into nonperforming status within the Corporate Finance portfolio. Nonperforming commercial finance receivables and loans as a percentage of outstanding commercial finance receivables and loans remained flat at 0.2% at both March 31, 2015, and December 31, 2014.

Commercial Criticized Exposure

Finance receivables and loans classified as special mention, substandard, or doubtful are deemed criticized. These classifications are based on regulatory definitions and generally represent finance receivables and loans within our portfolio that have a higher default risk or have already defaulted. These finance receivables and loans require additional monitoring and review including specific actions to mitigate our potential loss.

The following table presents the percentage of total commercial criticized finance receivables and loans by industry concentrations. These finance receivables and loans within our Automotive and Corporate Finance portfolios are reported at carrying value before allowance for loan losses.

The allowance for consumer loan losses at March 31, 2015, declined$218 million compared to March 31, 2014. The decrease was primarily due to the transfer of consumer mortgage assets to held-for-sale as of the year ended December 31, 2014, combined with the continued runoff of legacy mortgage assets within our Mortgage operations.

The allowance for commercial loan losses declined$41 million at March 31, 2015, compared to March 31, 2014, primarily due to continued strong performance in the portfolio.

The provision for consumer loan losses increased$13 million for the three months endedMarch 31, 2015, compared to the same period in 2014. The increase was primarily due to lower reserve releases on mortgage assets.

The provision for commercial loan losses was a net credit of $37 million for the three months ended March 31, 2015, compared to a net credit of $3 million for the same period in 2014. This decrease was largely driven by reserve releases due to continued strong performance in the portfolio.

Lease Residual Risk Management

We are exposed to residual risk on vehicles in the consumer lease portfolio. This lease residual risk represents the possibility that the actual proceeds realized upon the sale of returned vehicles will be lower than the projection of these values used in establishing the pricing at lease inception. For information on our valuation of automotive lease residuals including periodic revisions through adjustments to depreciation expense based on current and forecasted market conditions, refer to Critical Accounting Estimates — Valuation of Automotive Lease Assets and Residuals within the MD&A included in our 2014 Annual Report on Form 10-K.

Lease Vehicle Terminations and Remarketing

The following table summarizes the volume of Ally lease terminations and average gain per vehicle in the United States over recent periods, as well as our methods of vehicle sales at lease termination, stated as a percentage of total lease vehicle disposals. The actual gain per vehicle on lease terminations varies based upon the type of vehicle.

	Three months ended March 31,
	2015			2014
Off-lease vehicles terminated (in units)	65,060			61,001
Average gain per vehicle ($ per unit)	$	1,067		$	1,791
Method of vehicle sales
Auction (internet and physical)	63		%	59		%
Sale to dealer, lessee, and other	37			41

The number of off-lease vehicles remarketed during the three months endedMarch 31, 2015 increased 7% as compared to the same period in 2014. While we expect lease termination volumes to continue to remain near current levels throughout 2015, actual termination volumes may vary in the future from forecasted volumes due to programs designed to encourage lessees to terminate their leases early in conjunction with the acquisition of a new vehicle, referred to as lease pull-ahead programs. GM’s recent decision to provide lease subvention programs for Buick, GMC, and Cadillac products exclusively through its wholly-owned subsidiary, GMF, is not expected to affect lease termination volumes throughout 2015.

Average gain per vehicle decreased during the three months endedMarch 31, 2015, primarily due to lower lifetime depreciation recognized on terminated lease vehicles as a result of higher anticipated proceeds based on recent market conditions. For more information on our investment in operating leases, refer to Note 8 to the Condensed Consolidated Financial Statements, and Note 1 to the Consolidated Financial Statements in our 2014 Annual Report on Form 10-K.

Market Risk

Our automotive financing, mortgage, and insurance activities give rise to market risk representing the potential loss in the fair value of assets or liabilities and earnings caused by movements in market variables, such as interest rates, foreign-exchange rates, equity prices, market perceptions of credit risk, and other market fluctuations that affect the value of securities, assets held-for-sale, and operating leases. We are exposed to interest rate risk arising from changes in interest rates related to financing, investing, and cash management activities. More specifically, we have entered into contracts to provide financing and to retain various assets related to securitization activities all of which are exposed in varying degrees to changes in value due to movements in interest rates. Interest rate risk arises from the mismatch between assets and the related liabilities used for funding. We enter into various financial instruments, including derivatives, to maintain the desired level of exposure to the risk of interest rate and other fluctuations. Refer to Note 20 to the Condensed Consolidated Financial Statements for further information.

We are also exposed to some foreign-currency risk arising from foreign-currency denominated assets and liabilities, primarily in Canada. We enter into hedges to mitigate foreign exchange risk.

We also have exposure to equity price risk, primarily in our Insurance operations, which invests in equity securities that are subject to price risk influenced by capital market movements. We enter into equity options to economically hedge our exposure to the equity markets. Additionally, we have exposure to equity price risk related to certain share-based compensation. We enter into prepaid equity forward contracts to economically hedge a portion of this exposure.

Although the diversity of our activities from our complementary lines of business may partially mitigate market risk, we also actively manage this risk. We maintain risk management control systems to monitor interest rates, foreign-currency exchange rates, equity price risks, and any of their related hedge positions. Positions are monitored using a variety of analytical techniques including market value, sensitivity analysis, and value at risk models.

Net Financing Revenue Sensitivity Analysis

Interest rate risk represents our most significant exposure to market risk. We actively monitor the level of exposure so that movements in interest rates do not adversely affect future earnings. We use net financing revenue sensitivity analysis as our primary metric to measure and manage the interest rate sensitivities of our financial instruments.

We prepare forward-looking forecasts of net financing revenue, which take into consideration anticipated future business growth, asset/liability positioning, and interest rates based on the implied forward curve. Simulations are used to assess changes in net financing revenue in multiple interest rates scenarios relative to the baseline forecast. The changes in net financing revenue relative to the baseline are defined as the sensitivity. Our simulation incorporates contractual cash flows and repricing characteristics for all assets, liabilities and off-balance sheet exposures and incorporates the effects of changing interest rates on the prepayment and attrition rates of certain assets and liabilities. The analysis is highly dependent upon a variety of assumptions including the repricing characteristics of deposits with non-contractual maturities. Our simulation does not assume any specific future actions are taken to mitigate the impacts of changing interest rates.

The net financing revenue sensitivity tests measure the potential change in our pretax net financing revenue over the following twelve months. A number of alternative rate scenarios are tested, including immediate parallel shocks to the forward yield curve, nonparallel shocks to the forward yield curve, and stresses to certain term points on the yield curve in isolation to capture and monitor a number of risk types.

Our twelve-month pretax net financing revenue sensitivity based on the forward-curve was as follows.

Instantaneous Change in Interest Rates as of ($ in millions)	March 31, 2015			December 31, 2014
Parallel rate shifts (relative to the base forward-curve)
-100 basis points	$	31		$	78
+100 basis points	(89		)	(130		)
+200 basis points	(191		)	(215		)

We remain moderately liability sensitive as our simulation models assume liabilities will initially re-price faster than assets. A material portion of our interest rate exposure has been driven by Prime rate index floors on certain commercial loans that limit interest income increases until the index rises above the level of the floor. Due to market demand for our London Interbank Offered Rate (LIBOR)-based product and to reduce our exposure to rising interest rates, we have migrated a substantial portion of its dealer floorplan accounts from Prime to LIBOR indices. As of March 31, more than 60% of our floorplan assets will re-price directly with changes in LIBOR.

Our liability sensitive risk position is also driven by receive-fixed interest rate swaps designated as fair value hedges of certain fixed-rate liabilities including legacy unsecured debt. These swaps continue to generate positive financing revenue in the current interest rate environment, but also add to our liability sensitive position. The size, maturity and mix of our hedging activities change frequently as we adjust our broader asset and liability management objectives.

The future repricing behavior of retail deposit liabilities, particularly non-maturity deposits, remains a significant driver of interest rate sensitivity. The sustained low interest rate environment increases the uncertainty of assumptions for deposit repricing relationships to market interest rates. Our interest rate risk models use dynamic assumptions driven by a number of factors, including the overall level of interest rates and the spread between short-term and long-term interest rates to project changes in our retail deposit offered rates. Ally’s interest rate risk metrics currently assume a long-term retail deposit beta of greater than 80%. We believe our deposits may ultimately be less sensitive to interest rate changes, which will reduce our overall exposure to rising rates.

The adverse impact of upward shock scenarios has decreased since December 31, 2014, driven primarily by the migration of dealer floorplan accounts to LIBOR-based indices as noted and discussed above. The positive impact of downward rate shocks remains somewhat muted by the current low interest rate environment, which limits absolute declines in short-term rates in a shock scenario.

Liquidity Management, Funding, and Regulatory Capital

Overview

The purpose of liquidity management is to ensure our ability to meet loan and lease demand, debt maturities, deposit withdrawals, and other cash commitments under both normal operating conditions as well as periods of economic or financial stress. Our primary objective is to maintain cost-effective, stable and diverse sources of funding capable of sustaining the organization throughout all market cycles. Sources of funding include both retail and brokered deposits and secured and unsecured market-based funding across various maturity, interest rate, and investor profiles. Additional liquidity is available through a pool of unencumbered highly liquid securities, borrowing facilities, repurchase agreements, as well as funding programs supported by the Federal Reserve and the Federal Home Loan Bank of Pittsburgh (FHLB).

We define liquidity risk as the risk that an institution's financial condition or overall safety and soundness is adversely affected by an inability, or perceived inability, to meet its financial obligations, and to withstand unforeseen liquidity stress events. Liquidity risk can arise from a variety of institution specific or market-related events that could have a negative impact on cash flows available to the organization. Effective management of liquidity risk helps ensure an organization's preparedness to meet cash flow obligations caused by unanticipated events. Managing liquidity needs and contingent funding exposures has proven essential to the solvency of financial institutions.

The Asset-Liability Committee (ALCO) is chaired by the Corporate Treasurer and is responsible for overseeing our liquidity, funding strategies and plans, contingency funding plans, and counterparty credit exposure arising from financial transactions. Corporate Treasury is responsible for managing our liquidity positions within prudent operating guidelines and targets approved by ALCO and the Risk and Compliance Committee of the Ally Financial Board of Directors. Liquidity risk is managed for the parent company, Ally Bank, and the consolidated organization. The parent company and Ally Bank prepare periodic forecasts depicting anticipated funding needs and sources of funds with oversight and monitoring by the Liquidity Risk group within Corporate Treasury. Corporate Treasury executes our funding strategies and manages liquidity under baseline economic projections as well as more severely stressed macroeconomic environments.

Multiple measures are used to frame the level of liquidity risk, manage the liquidity position, or identify related trends. These measures include coverage ratios that measure the sufficiency of the liquidity portfolio and stability ratios that measure longer-term structural liquidity. In addition, we have established internal management routines designed to review all aspects of liquidity and funding plans, evaluate the adequacy of liquidity buffers, review stress testing results, and assist senior management in the execution of its funding strategy and risk management accountabilities.

We maintain available liquidity in the form of cash, unencumbered highly liquid securities, and available credit facility capacity that, taken together, allows us to operate and to meet our contractual and contingent obligations in the event of market-wide disruptions and enterprise-specific events. The available liquidity is held at various entities and considers regulatory restrictions and tax implications that may limit our ability to transfer funds across entities. At March 31, 2015, we maintained $8.7 billion of total available parent company liquidity and $10.5 billion of total available liquidity at Ally Bank. Parent company liquidity is defined as our consolidated operations less Ally Bank and the regulated subsidiaries of Ally Insurance's holding company. To optimize cash between entities, the parent company lends cash to Ally Bank on occasion under an intercompany loan agreement. At March 31, 2015, $700 million was outstanding under the intercompany loan agreement. Amounts outstanding are repayable to the parent company upon demand, subject to a five day notice period. As a result, this amount is included in the parent company available liquidity and excluded from the available liquidity at Ally Bank.

Funding Strategy

Liquidity and ongoing profitability are largely dependent on the timely and cost-effective access to retail deposits and funding in different segments of the capital markets. Our funding strategy largely focuses on the development of diversified funding sources across a broad investor base to meet liquidity needs throughout different market cycles, including periods of financial distress. These funding sources include wholesale and retail unsecured debt, public and private asset-backed securitizations, whole-loan sales, committed credit facilities, brokered deposits, and retail deposits. We also supplement these funding sources with a modest amount of short-term borrowings, including Demand Notes, and repurchase arrangements. The diversity of our funding sources enhances funding flexibility, limits dependence on any one source, and results in a more cost-effective funding strategy over the long term. We evaluate funding markets on an ongoing basis to achieve an appropriate balance of unsecured and secured funding sources and maturity profiles. In addition, we further distinguish our funding strategy between Ally Bank funding and parent company (nonbank) funding.

We diversify Ally Bank's overall funding in order to reduce reliance on any one source of funding and to achieve a well-balanced funding portfolio across a spectrum of risk, duration, and cost of funds characteristics. We optimize our funding sources at Ally Bank by growing retail deposits, maintaining active public and private securitization programs, managing a prudent maturity profile of our brokered deposit portfolio, utilizing repurchase agreements, and continuing to access funds from the FHLB.

Since 2009, a significant portion of asset originations in the United States have been directed to Ally Bank in order to reduce parent company exposures and funding requirements, and to utilize our growing consumer deposit-taking capabilities. This has allowed us to use bank funding for a wider array of our automotive finance assets and to provide a sustainable long-term funding channel for the business, while also improving the cost of funds for the enterprise.

Ally Bank

Ally Bank gathers retail deposits directly from customers through direct banking via the internet, telephone, mobile, and mail channels. These retail deposits provide our Automotive Finance, Mortgage, and Corporate Finance operations with a stable and low-cost funding source. At March 31, 2015, Ally Bank had $60.6 billion of total external deposits, including $50.6 billionof retail deposits.

At March 31, 2015, Ally Bank maintained cash liquidity of $4.0 billion and unencumbered highly liquid U.S. federal government and U.S. agency securities of $5.7 billion. In addition, at March 31, 2015, Ally Bank had unused capacity in committed secured funding facilities of $1.5 billion. Our ability to access unused capacity depends on having eligible assets to collateralize the incremental funding and, in some instances, the execution of interest rate hedges. To optimize cash between entities, the parent company lends cash to Ally Bank on occasion under an intercompany loan agreement. Amounts outstanding on this loan are repayable to the parent company upon demand, subject to a five day notice period. Ally Bank had total available liquidity of $10.5 billion at March 31, 2015, excluding the intercompany loan of $700 million.

Optimizing bank funding continues to be a key part of our long-term liquidity strategy. We have made significant progress in migrating asset originations to Ally Bank and growing our retail deposit base since becoming a BHC in December 2008. Retail deposit growth is a key driver of optimizing funding costs and reducing reliance on capital markets based funding. We believe deposits provide a stable, low-cost source of funds that are less sensitive to interest rate changes, market volatility, or changes in credit ratings when compared to other funding sources. We have continued to expand our deposit gathering efforts through both direct and indirect marketing channels. Current retail deposit offerings consist of a variety of products including CDs, savings accounts, money market accounts, IRA deposit products, as well as an interest checking product. In addition, we utilize brokered deposits, which are obtained through third-party intermediaries. In the first three months of 2015 the deposit base at Ally Bank grew $2.7 billion, ending the quarter at $60.6 billion from $57.9 billion at December 31, 2014. The growth in deposits has been primarily attributable to our retail deposit portfolio, particularly within our savings and money market accounts. Strong retention rates continue to materially contribute to our growth in retail deposits. Refer to Note 12 to the Condensed Consolidated Financial Statements for a summary of deposit funding by type.

The following table shows Ally Bank's number of accounts and deposit balances by type as of the end of each quarter since 2014.

($ in millions)	1st Quarter 2015		4th Quarter 2014		3rd Quarter 2014		2nd Quarter 2014		1st Quarter 2014
Number of retail accounts	1,818,770		1,731,105		1,698,585		1,641,327		1,589,441

Total deposits	$	60,565	$	57,903	$	56,483	$	55,693	$	54,946

(a) Other deposits include mortgage escrow and other deposits (excluding intercompany deposits).

In addition to building a larger deposit base, we continue to remain active in the securitization markets to finance our Ally Bank automotive loan portfolios. During the first quarter of 2015, Ally Bank completed three term securitization transactions backed by dealer floorplan and automotive lease notes that raised $1.4 billion. Ally Bank also executed a $1.0 billion whole-loan sale comprised of retail automotive loans.

Securitization has proven to be a reliable and cost-effective funding source. Additionally, for retail automotive loans and lease notes, the term structure of the transaction locks in funding for a specified pool of loans and leases for the life of the underlying asset, creating an effective tool for managing interest rate and liquidity risk. We manage secured funding execution risk by maintaining a diverse investor base and available committed credit facility capacity. Ally Bank has exclusive access to a syndicated credit facility comprised of eighteen lenders that can fund automotive retail and dealer floorplan loans, as well as leases. During March 2015, this facility was renewed and increased to $4.5 billion with the maturity extended to March 2017. At March 31, 2015, the amount outstanding under this facility was $3.0 billion. Our ability to access the unused capacity in the secured facility depends on the availability of eligible assets to collateralize the incremental funding and, in some instances, on the execution of interest rate hedges.

Ally Bank also has access to funding through advances with the FHLB. These advances are primarily secured by consumer and commercial mortgage finance receivables and loans. As of March 31, 2015, Ally Bank had pledged $10.8 billion of assets and investment securities to the FHLB resulting in $7.0 billion in total funding capacity with $3.8 billion of debt outstanding.

In addition, Ally Bank has access to repurchase agreements. A repurchase agreement is a transaction in which the firm sells financial instruments to a buyer, typically in exchange for cash, and simultaneously enters into an agreement to repurchase the same or substantially the same financial instruments from the buyer at a stated price plus accrued interest at a future date. The financial instruments sold in repurchase agreements typically include U.S. government and federal agency, and investment-grade sovereign obligations. As of March 31, 2015, Ally Bank had $681 million of debt outstanding under repurchase agreements.

Additionally, Ally Bank has access to the Federal Reserve Bank Discount Window and can borrow funds to meet short-term liquidity demands. However, the Federal Reserve Bank is not a primary source of funding for day to day business. Instead, it is a liquidity source that can be accessed in stressed environments or periods of market disruption. Ally Bank has assets pledged and restricted as collateral to the Federal Reserve Bank totaling $3.3 billion. Ally Bank had no debt outstanding with the Federal Reserve as of March 31, 2015.

Parent Company (Nonbank) Funding

At March 31, 2015, the parent company maintained liquid cash and equivalents in the amount of $3.0 billion as well as unencumbered highly liquid U.S. federal government and U.S. agency securities of $2.1 billion that can be used to obtain funding through repurchase agreements with third parties or outright sales. At March 31, 2015, the parent company had $1.5 billion debt outstanding under repurchase agreements. In addition, at March 31, 2015, the parent company had available liquidity from unused capacity in committed credit facilities of $2.9 billion. Parent company liquidity is defined as our consolidated operations less Ally Bank and the regulated subsidiaries of Ally Insurance's holding company. The parent company's ability to access unused capacity in secured facilities depends on the availability of eligible assets to collateralize the incremental funding and, in some instances, on the execution of interest rate hedges. Funding sources at the parent company generally consist of long-term unsecured debt, unsecured retail term notes, committed credit facilities, asset-backed securitizations, and a modest amount of short-term borrowings. To optimize cash and secured facility capacity between entities, the parent company lends cash to Ally Bank on occasion under an intercompany loan agreement. Amounts outstanding on this loan are repayable to the parent company upon demand, subject to a five day notice period. The parent company had total available liquidity of $8.7 billion at March 31, 2015, which included the intercompany loan of $700 million.

In the first quarter of 2015, we completed several transactions through the unsecured debt capital markets totaling $2.5 billion. In addition, Ally Financial Inc. completed a tender offer to buy back $950 million of its high-coupon debt. We recorded a loss of $197 million on extinguishment of debt in the first quarter related to this transaction. We expect to continue accessing the unsecured debt capital markets as well as pursuing tender offers on high-cost debt on an opportunistic basis.

In addition, we have short-term and long-term unsecured debt outstanding from retail term note programs. These programs generally consist of callable fixed-rate instruments with fixed-maturity dates. There were $341 million and $335 million of retail term notes outstanding at March 31, 2015, and December 31, 2014, respectively.

We also obtain unsecured funding from the sale of floating-rate demand notes under our Demand Notes program. The holder has the option to require us to redeem these notes at any time without restriction. Demand Notes outstanding were $3.5 billion at March 31, 2015, compared to $3.3 billion at December 31, 2014. Refer to Note 13 and Note 14 to the Condensed Consolidated Financial Statements for additional information about our outstanding short-term borrowings and long-term unsecured debt, respectively.

Secured funding continues to be a significant source of financing at the parent company. The total capacity in our committed funding facilities is provided by banks and other financial institutions through private transactions. The committed secured funding facilities can be revolving in nature and allow for additional funding during the commitment period, or they can be amortizing and not allow for any further funding after the closing date. At March 31, 2015, $17.2 billion of our $18.1 billion of committed capacity was revolving. Our revolving facilities generally have an original tenor ranging from 364 days to two years. As of March 31, 2015, we had $13.4 billion of committed funding capacity from revolving facilities with a remaining tenor greater than 364 days. The parent company's largest facility is an $8.0 billion revolving syndicated credit facility secured by automotive receivables. In March 2015, this facility was renewed by a syndicate of eighteen lenders and extended until March 2017. In the event this facility is not renewed at maturity, the outstanding debt will be repaid over time as the underlying collateral amortizes. At March 31, 2015, there was $8.0 billion outstanding under this facility. In addition to our syndicated revolving credit facility, we also maintain various bilateral and multilateral secured credit facilities that fund our Automotive Finance operations. These are primarily private securitization facilities that fund a specific pool of automotive assets.

During the first quarter of 2015, the parent company raised $1.3 billion through a public securitization transaction comprised of nonprime retail automotive loan collateral.

At March 31, 2015, the parent company maintained exclusive access to $18.1 billion of committed secured credit facilities with outstanding debt of $15.2 billion.

Recent Funding Developments

During the first three months of 2015, we accessed the public and private markets to execute secured funding transactions, a whole-loan sale, unsecured funding transactions, and funding facility renewals totaling $18.7 billion. Key funding highlights from January 1, 2015 to date were as follows:

• Ally Financial Inc. renewed, increased, and/or extended $12.5 billion in U.S. credit facilities. The automotive credit facility renewal amount includes the March 2015 refinancing of $12.5 billion in credit facilities at both the parent company and Ally Bank with a syndicate of eighteen lenders. The $12.5 billion capacity is secured by retail, lease, and dealer floorplan automotive assets and is allocated to two separate facilities; one is an $8.0 billion facility which is available to the parent company, while the other is a $4.5 billion facility available to Ally Bank. Both facilities mature in March 2017.

(a) Funding from committed secured facilities is available on request in the event excess collateral resides in certain facilities or is available to the extent incremental collateral is available and contributed to the facilities.

Cash Flows

Net cash provided by operating activities was $247 million for the three months ended March 31, 2015, compared to $932 million for the same period in 2014. The decrease in net cash provided by operating activities was primarily due to a decrease in new originations and purchases of loans held-for-sale exceeding cash inflows from sales and repayments of such loans by $1.1 billion.

Net cash provided by investing activities was $805 million for the three months ended March 31, 2015, compared to $2.1 billion for the same period in 2014. The decrease in net cash provided from investing activities was primarily due to a $2.6 billion decrease in net cash provided by sales, maturities and repayment of available-for-sale securities, net of purchases, and a $1.7 billion decrease in restricted cash. This was partially offset by an increase in net cash provided by finance receivables and loans of $1.0 billion, an increase in net cash inflows from operating lease activity of $1.0 billion, and $1.0 billion in proceeds from the sale of a business unit.

Net cash provided by financing activities for the three months ended March 31, 2015, was $1.0 billion, compared to net cash used in financing activities of $2.7 billion for the same period in 2014. The increase was primarily due to lower repayments of short-term borrowings of $2.8 billion and long-term debt of $905 million.

Capital Planning and Stress Tests

As a BHC with $50 billion or more of consolidated assets, Ally is required to conduct periodic internal stress tests, is subject to an annual supervisory stress test conducted by the Board of Governors of the Federal Reserve System (FRB), and must submit an annual capital plan to the FRB. In October 2014, the FRB issued instructions and scenarios for the 2015 capital planning and stress test processes.

Ally’s capital plan must include a description of all planned capital actions over a nine-quarter planning horizon. The capital plan must also include a discussion of how Ally will maintain capital above the minimum regulatory capital ratios and above a Tier 1 common equity-to-total risk-weighted assets ratio of 5% under baseline, adverse, and severely adverse economic scenarios, and serve as a source of strength to Ally Bank. The FRB must approve Ally's capital plan before Ally may take any capital action. Even with an approved capital plan, Ally must seek the approval of the FRB before making a capital distribution if, among other factors, Ally would not meet its regulatory capital requirements after making the proposed capital distribution.

On January 5, 2015, Ally Financial Inc. submitted the results of its semi-annual stress test and its proposed capital actions to the FRB, and Ally Bank submitted the results of its annual company-run stress test to the Federal Deposit Insurance Corporation. On March 6, 2015, Ally Financial Inc. and Ally Bank publicly disclosed summary results of the stress test under the most severe scenario in accordance with regulatory requirements. On March 11, 2015, Ally received a non-objection to its capital plan from the FRB, including the proposed capital actions contained in its submission. As a result, we redeemed $1.3 billion in Series G preferred securities in April 2015, and announced a tender offer to purchase up to 13 million shares of our outstanding Series A preferred securities for $26.65 per share. We also plan to redeem additional preferred securities through the remainder of 2015 and 2016, as well as repurchase additional high-cost unsecured debt as part of our ALM initiatives.

Regulatory Capital

Refer to Note 19 to the Condensed Consolidated Financial Statements and Selected Financial Data within this MD&A.

Credit Ratings

The cost and availability of unsecured financing are influenced by credit ratings, which are intended to be an indicator of the creditworthiness of a particular company, security, or obligation. Lower ratings result in higher borrowing costs and reduced access to capital markets. This is particularly true for certain institutional investors whose investment guidelines require investment-grade ratings on term debt and the two highest rating categories for short-term debt (particularly money market investors).

Nationally recognized statistical rating organizations rate substantially all our debt. The following table summarizes our current ratings and outlook by the respective nationally recognized rating agencies.

Rating agency	Short-term	Senior debt	Outlook	Date of last action
Fitch	B	BB+	Stable	April 8, 2015 (a)
Moody’s	Not Prime	B1	Positive	July 14, 2014 (b)
S&P	B	BB+	Stable	December 12, 2014 (c)
DBRS	R-4	BB	Positive	September 17, 2014 (d)

(a) Fitch affirmed our senior debt rating of BB+, affirmed our short term rating of B and maintained a Stable outlook on April 8, 2015.

(b) Moody's affirmed our corporate family rating of Ba3, senior debt rating of B1, and short-term rating of Not Prime and changed the outlook to Positive on July 14, 2014. Effective December 1, 2014, we determined to not renew our contractual arrangement with Moody's related to their providing of our corporate family, senior debt, and short-term ratings. Notwithstanding this, Moody's has determined to continue to provide these ratings on a discretionary basis. However, Moody's has no obligation to continue to provide these ratings, and could cease doing so at any time.

(c) Standard & Poor's upgraded our senior debt rating to BB+ from BB and affirmed our short term rating of B on December 12, 2014.

(d) DBRS confirmed our senior debt rating of BB, confirmed our short term rating of R-4, and changed the trend on Ally's senior debt to Positive on September 17, 2014.

Management's Discussion and Analysis

Ally Financial Inc. • Form 10-Q

Recently Issued Accounting Standards

Refer to Note 1 to the Condensed Consolidated Financial Statements.

Forward-looking Statements

The foregoing Management’s Discussion and Analysis of Financial Condition and Results of Operations and other portions of this Form 10-Q contain various forward-looking statements within the meaning of applicable federal securities laws, including the Private Securities Litigation Reform Act of 1995, that are based upon our current expectations and assumptions concerning future events that are subject to a number of risks and uncertainties that could cause actual results to differ materially from those anticipated.

The words “expect,” “anticipate,” “estimate,” “forecast,” “initiative,” “objective,” “plan,” “goal,” “project,” “outlook,” “priorities,” “target,” “intend,” “evaluate,” “pursue,” “seek,” “may,” “would,” “could,” “should,” “believe,” “potential,” “continue,” or the negatives of any of these words or similar expressions are intended to identify forward-looking statements. All statements herein, other than statements of historical fact, including without limitation statements about future events and financial performance, are forward-looking statements that involve certain risks and uncertainties.

While these statements represent our current judgment on what the future may hold, and we believe these judgments are reasonable, these statements are not guarantees of any events or financial results, and Ally's actual results may differ materially due to numerous important factors that are described in the most recent reports on SEC Forms 10-K and 10-Q for Ally, each of which may be revised or supplemented in subsequent reports filed with the SEC. Such factors include, among others, the following: maintaining the mutually beneficial relationship between Ally and General Motors, and Ally and Chrysler, and our ability to further diversify our business; the significant regulation and restrictions that we are subject to as a bank holding company and financial holding company; the potential for deterioration in the residual value of off-lease vehicles; disruptions in the market in which we fund our operations, with resulting negative impact on our liquidity; changes in our accounting assumptions that may require or that result from changes in the accounting rules or their application, which could result in an impact on earnings; changes in our credit ratings; changes in economic conditions, currency exchange rates or political stability in the markets in which we operate; and changes in the existing or the adoption of new laws, regulations, policies or other activities of governments, agencies and similar organizations (including as a result of the Dodd-Frank Act and Basel III).

Use of the term “loans” describes products associated with direct and indirect lending activities of Ally’s global operations. The specific products include retail installment sales contracts, loans, lines of credit, leases or other financing products. The term “originate” refers to Ally’s purchase, acquisition, or direct origination of various “loan” products.

Controls and Procedures

Ally Financial Inc. • Form 10-Q

Item 4.    Controls and Procedures

We maintain disclosure controls and procedures, as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act), designed to ensure that information required to be disclosed in reports filed under the Exchange Act is recorded, processed, summarized, and reported within the specified time periods. Our disclosure controls and procedures are also designed to ensure that information required to be disclosed in the reports we file and submit under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer (Principal Financial Officer), to allow timely decisions regarding required disclosure.

As of the end of the period covered by this report, our Principal Executive Officer and Principal Financial Officer evaluated, with the participation of our management, the effectiveness of our disclosure controls and procedures and concluded that our disclosure controls and procedures were effective.

There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) that occurred during our most recent fiscal quarter that materially affected, or were reasonably likely to materially affect, our internal control over financial reporting.

Our management, including our Principal Executive Officer and Principal Financial Officer, does not expect that our disclosure controls or our internal controls will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within Ally have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with associated policies or procedures. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

EX-10.1

RELEASE AGREEMENT

Barbara A. Yastine and Ally Financial Inc. have reached the following Release Agreement. In this Release Agreement, "Employee" refers to Barbara A. Yastine, and "Company" refers to Ally Financial Inc., its shareholders, subsidiaries, affiliates and divisions, predecessors and successors, joint ventures, employee benefit plans, directors, officers, agents, employees, and assigns, including but not limited to IB Finance Holding Company, LLC and Ally Bank.

WHEREAS Company and Employee have decided it is in their best interest to terminate their employment relationship according to the terms set forth below, the parties agree as follows:

1. Provided that this signed and notarized document is received by James J. Duffy, Ally Financial Inc. Group Vice President and Chief Human Resources Officer, 1177 Avenue of the Americas, New York, NY 10036, no later than March 31, 2015 and not revoked in accordance with Paragraph 18, Employee’s termination of employment will be reflected as a Mutually Satisfactory Separation effective June 19, 2015. Until then, effective on the date the seven (7) day revocation period referred to in Paragraph 18 of this Release Agreement expires, Employee will resign from her positions as Chairperson, CEO, and President of Ally Bank, and all related board positions, and commence a transitional assignment as an advisor to the Company CEO and Board of Directors as requested. Except as required to perform such requested tasks, Employee shall have no obligation to be present in Company’s business offices. During this transition, she will receive cash compensation equal to her 2014 total direct compensation rate of $425,000 per month (“Transition Compensation Rate”)

and remain eligible for all the benefits to which other active Company employees are eligible and subject to all the terms and conditions of employment to which other active Company employees are subject.

2. The Company and Employee have agreed on the wording of the announcement of Employee’s separation, which has been appended to this Release Agreement as Exhibit 1. The parties agree that the public disclosure and discussion about Employee’s employment and separation will be consistent with this announcement.

3. Employee agrees that the separation status, compensation, and consideration referred to in Paragraph 1 are more than the Company is required to provide under its normal policies and procedures. Employee agrees to remain actively employed in good standing and meet the specific objectives required of her transitional assignment until June 19, 2015. Notwithstanding the above, if Employee wishes to terminate her employment prior to June 19, 2015, she will provide the Company with two (2) weeks advance notice, at which point the Company may agree to a new separation date and pay Employee her Transition Compensation Rate (but no benefits) as if she remained employed through June 19, 2015. If the Company does not agree to the new separation date, which agreement will not be unreasonably withheld, Employee’s separation will be deemed a Voluntarily Resignation effective two (2) weeks from the date of her notice, and Employee will forfeit any right to continued payment of the Transition Compensation Rate or Company benefits under this Release Agreement as of her separation date. Under either scenario, the release language contained in Paragraph 4 will remain in full force and effect.

4. Employee for herself, family, heirs and representatives further agrees that, by entering into this Release Agreement, she releases the Company from all claims or demands she may have based on her employment with the Company, this Release Agreement, or the termination of her employment. This release specifically includes, without limitation, a release of any rights or claims she may have under:

• the Employee Retirement Income Security Act of 1974, as amended, which regulates employee benefit plans;

• Title VII of the Civil Rights Act of 1964, as amended, the Civil Rights and Women’s Equity Act of 1991, as amended, and the Equal Pay Act of 1963, as amended, which prohibit discrimination in employment based on race, color, national origin, religion, or sex;

• the Age Discrimination in Employment Act, which prohibits discrimination based on age;

• the Rehabilitation Act of 1973, as amended, and the Americans with Disabilities Act, as amended, which prohibit discrimination based on disability;

• the Family Medical Leave Act, as amended;

• the Worker Adjustment and Retraining Notification Act (WARN), as amended;

• the National Labor Relations Act, as amended;

• state fair employment practices or civil rights laws;

• the Dodd-Frank Wall Street Reform and Consumer Protection Act, as amended, and Sarbanes-Oxley Act of 2002, as amended, which govern whistleblower claims by financial services employees; and

• any other federal, state, or local laws, or regulations, or any common law actions relating to employment, or employment discrimination.

This includes, without limitation, any claims for breach of employment contract, either expressed or implied, violation of public policy, breach of implied covenant of good faith and fair dealing, intentional infliction of emotional distress, negligent infliction of emotional distress, fraud, false imprisonment, invasion of privacy, commercial or trade defamation, defamation, slander, libel, tort, and wrongful discharge. This release does not foreclose Employee’s ability to file an administrative charge with the Equal Employment Opportunity Commission (“EEOC”), however, Employee expressly waives any right or claim to monetary relief in relation to any charge she files should any administrative agency, including but not limited to the EEOC, pursue any claim on Employee’s behalf to the maximum extent permitted by law. This release does not include any claims to: (a) vested 401(k) pension benefits; (b) vested deferred compensation such as deferred stock units; (c) unemployment compensation; or (d) enforce the terms of this Release Agreement. This release covers all claims accrued or un-accrued, known or unknown, up to the effective date of this Release Agreement. If any claim is not subject to release, to the extent permitted by law, Employee waives any right or ability to be a class or collective action representative or to otherwise participate in any putative or certified class, collective or multi-party action or proceeding based on such a claim in which Company is a

party.  Employee promises not to consent to become a member of any class or collective in a case in which claims are asserted against Company that are related in any way to her employment or the termination of her employment with Company. If Employee is made a member of a class in any such proceeding, she will immediately opt out of the class.

5. Employee understands and agrees that she is not eligible for severance benefits under the Ally Financial Inc. Severance Plan – any claim to which Employee expressly waives by signing this Release Agreement.

6. The Company makes this Release Agreement to avoid the cost of defending against any possible lawsuit or claims. By making this Release Agreement, the Company does not admit that it has done anything wrong.

7. If the Company successfully asserts this Release Agreement as a defense against a future lawsuit or claim of Employee, Employee will pay for all costs incurred by the Company, including reasonable attorney’s fees, in defending against her claim, unless such lawsuit or claim is brought by Employee for purposes of enforcing this Release Agreement.

8. Employee is advised to consult with an attorney before signing this Release Agreement. Employee understands that whether or not she does so is her decision. Employee will have until March 31, 2015 to accept or reject this Release Agreement.

Nothing in this Agreement prohibits Employee or her attorney from initiating communications directly with, or responding to any inquiry from or providing testimony before, the SEC, FINRA, or any other self-regulatory organization or any other state or federal regulatory authority or responding to any subpoena or other legal process. Employee acknowledges that a breach of this Paragraph 10 will entitle Company to legal and equitable relief.

11. Employee acknowledges that she is able to work and suffers from no disability that would preclude her from doing her regularly assigned job.

12. Employee understands and agrees that the existence and terms of this Release Agreement may be publicly disclosed in accordance with applicable law; provided however, that the negotiations, discussions, and proceedings leading up to this Release Agreement are confidential, and that neither she, nor her attorney, nor any individual

acting on her behalf may disclose these matters to any person or entity, except as expressly required by law.

13. Employee agrees to cooperate with the Company and its legal counsel on any matters relating to the conduct of any administrative or judicial litigation, claim, suit, investigation or proceeding involving the Company in connection with any facts or circumstances occurring during her employment with the Company.

Except as otherwise specifically provided below, the obligations of the Company to you which arise upon the termination of your employment pursuant to this Letter Agreement shall not be subject to mitigation or offset.

         You agree that you will not at any time publish or communicate to any person or entity any Disparaging (as defined below) remarks, comments or statements concerning the Company, its parent, subsidiaries and affiliates, and their respective present and former members, partners, directors, officers, shareholders, employees, agents, attorneys, successors and assigns. The Company agrees to instruct its executive officers and directors to refrain from publishing or communicating to any person or entity any Disparaging remarks, comments or statements concerning you at any time, provided that, nothing shall prevent either you or the Company from (a) responding in a truthful manner to inquiries regarding your employment or the termination thereof, from investors, regulators, the Company’s auditors or insurers, or as otherwise may be required by applicable law, rules or regulations, or (b) disclosing information concerning your employment, or the termination of your employment, to officers of the Company or its affiliates who, at the discretion of the Company, should know such information. “Disparaging” remarks, comments or statements are those that impugn the character, honesty, integrity or morality or business acumen or abilities of the individual or entity being disparaged in connection with any aspect of the operation of business. Nothing in this paragraph shall prohibit the reporting of

2

misconduct by any party to any court of law, any governmental agency having supervisory authority over the business of the Company or any administrative or legislative body (including a committee thereof) of the government of the U.S. or any state of the U.S. (any or all, “Government Authority”).

         During the course of your employment by the Company, you had access to certain trade secrets and confidential information relating to the Company and its subsidiaries (the “Protected Parties”) which is not readily available from sources outside the Company. The confidential and proprietary information and, in any material respect, trade secrets of the Protected Parties are among their most valuable assets, including, but not limited to, their customer, supplier and vendor lists, databases, competitive strategies, computer programs, frameworks, or models, their marketing programs, their sales, financial, marketing, training and technical information, their product development (and proprietary product data) and any other information, whether communicated orally, electronically, in writing or in other tangible forms concerning how the Protected Parties create, develop, acquire or maintain their products and marketing plans, target their potential customers and operate their retail, investment and other businesses. The Protected Parties invested, and continue to invest, considerable amounts of time and money in their process, technology, know-how, obtaining and developing the goodwill of their customers, their other external relationships, their data systems and data bases, and all the information described above (hereinafter collectively referred to as “Confidential Information”), and any misappropriation or unauthorized disclosure of Confidential Information in any form would irreparably harm the Protected Parties. You acknowledge that such Confidential Information constitutes valuable, highly confidential, special and unique property of the Protected Parties. You shall hold in a fiduciary capacity for the benefit of the Protected Parties all Confidential Information relating to the Protected Parties and their businesses, which shall have been obtained by you during your employment by the Company or its subsidiaries and which shall not be or become public knowledge (other than by acts by you or your representatives in violation of this Letter Agreement). You shall not disclose any Confidential Information, directly or indirectly, to any person or entity for any reason or purpose whatsoever, nor shall you use it in any way, except (i) in the course of your consulting services as provided above, (ii) to enforce any rights or defend any claims hereunder or under any other agreement to which you are a party, provided that such disclosure is relevant to the enforcement of such rights or defense of such claims and is only disclosed in the formal proceedings related thereto, (iii) as may be ordered by, or in the context of,

3

reporting misconduct to a Government Authority, (iv) as to such Confidential Information that becomes generally known to the public or trade without your violation of this paragraph of this Letter Agreement or (v) to your spouse, attorney and/or your personal tax and financial advisors as reasonably necessary or appropriate to advance your tax, financial and other personal planning (each an “Exempt Person”), provided such Exempt Person agrees to hold such Confidential Information in confidence to the same extent that you are required to do so hereunder. You shall take all reasonable steps to safeguard the Confidential Information. You understand and agree that you shall acquire no rights to such Confidential Information, except as explicitly provided above.

        All originals and copies of documents, drawings, specifications, data, computer programs, electronic files, evaluation mechanisms and analytics and similar items (and the contents of thereof) containing Confidential Information, including all customer lists, specific customer information, compilations of product research and marketing techniques of the Company and its subsidiaries, whether prepared by you or otherwise coming into your possession, shall remain the exclusive property of the Company and its subsidiaries; provided, however, nothing in this Letter Agreement shall prevent you from retaining your personal notes, personal memoranda and personal correspondences and personal rolodexes.

         As requested by the Company and at the Company’s expense, you will promptly deliver to the Company and its subsidiaries all copies and embodiments, in whatever form, of all Confidential Information in your possession or within your control (including, but not limited to, memoranda, records, notes, plans, photographs, manuals, notebooks, documentation, program listings, flow charts, magnetic media, disks, diskettes, tapes, computer drives and all other materials containing any Confidential Information provided that this requirement does not apply to personal materials which you are permitted to retain as provided above).

    It is understood and agreed that while employed by the Company or its subsidiaries you assigned to the Company your interest in any invention, improvement or discovery made or conceived by you, either alone or jointly with others, in connection with your employment with the Company. At the Company’s request and expense, you will assist the Company and its subsidiaries (subject to reasonable notice and taking into account your schedule) in connection with any controversy or legal proceeding relating to such invention, improvement or

4

discovery and in obtaining domestic and foreign patent or other protection covering the same.

         Following the Termination Date, including but not limited to the Consulting Period, you will give your assistance and cooperation upon reasonable advance notice, with due consideration for your other business or personal commitments, with respect to any investigation or the Company’s defense or prosecution of any existing or future claims or litigations or other proceedings relating to matters in which you were involved or of which you had knowledge by virtue of your employment with the Company. This may include your cooperation in any matter relating to your position with the Company, or your expertise or experience, as the Company may reasonably request, including your attendance and truthful testimony when reasonably deemed appropriate by the Company. In no event shall our cooperation materially interfere with your services for a subsequent employer or other similar service recipient. To the extent permitted by law, the Company agrees that (i) it will promptly reimburse you for your reasonable and documented expenses in connection with your rendering assistance and/or cooperation requested under this paragraph upon your presentation of documentation for such expenses and (ii) you will be compensated at an agreed reasonable rate of pay for the services as requested under this paragraph rendered after the conclusion of the Consulting Period.

         During the 12-month period following the Termination Date, you shall not (a) directly or indirectly solicit or attempt to solicit or induce, directly or indirectly, any party who is a customer of the Company or its subsidiaries or who is a prospective customer that has been identified and targeted by the Company or its subsidiaries, for the purpose of marketing, selling or providing to any such party any services or products offered by or available from the Company or its subsidiariesor (b) directly or indirectly solicit or attempt to solicit any employee of the Company or any of its subsidiaries (a “Current Employee”) or any person who was an employee of the Company or any of its subsidiaries during the 60-day period immediately prior to the Termination Date (a “Former Employee”) to terminate such employee’s employment relationship with the Protected Parties in order, in either case, to enter into a similar relationship with you, or any other person or any entity or hire any employee or Former Employee. For the sake of clarity, nothing in this paragraph shall prevent you from providing referrals or recommendations on behalf of a Current Employee or a Former Employee.

5

        During the Consulting Period, you will not, whether individually, as a director, manager, member, stockholder, partner, owner, employee, consultant or agent of any business, or in any other capacity, other than on behalf of the Company or a subsidiary, organize, establish, own, operate, manage, control, engage in, participate in, invest in, permit your name to be used by, act as a consultant or advisor to, render services for (alone or in association with any person, firm, corporation or business organization), or otherwise assist any person or entity that engages in or owns, invests in, operates, manages or controls any venture or enterprise which engages or proposes to engage in any business conducted by the Company or any of its subsidiaries on the date of your termination of employment or within 6 months prior to your termination of employment in the geographic locations where the Company and its subsidiaries engage, or have active plans to engage, of which you are aware, in such business (the “Business”). Notwithstanding the foregoing, nothing in this Letter Agreement shall prevent you from (i) owning for passive investment purposes not intended to circumvent this Letter Agreement, less than five percent (5%) of the publicly traded common equity securities of any company engaged in the Business (so long as you have no power to manage, operate, or control the competing enterprise and no power, alone or in conjunction with other affiliated parties, to select a director, manager, general partner, or similar governing official of the competing enterprise other than in connection with the voting powers afforded you in connection with customary equity ownership), (ii) being employed by or otherwise associated with an organization or entity of which a subsidiary, division, segment, unit, etc. is engaged in the Business (a “Competing Division”), provided that (x) you have no direct or indirect responsibilities or involvement with such Competing Division, (y) the Competing Division does not account for more than 20% of the gross revenues of such organization or entity for its prior fiscal year and (z) the Business that is competitive with the Company or any of its Subsidiaries does not account for more than 20% of the gross revenues of the Company and its Subsidiaries.

         We both acknowledge and agree that your breach or threatened breach of any of the restrictive covenants as set forth above will result in irreparable and continuing damage to the Protected Parties for which there may be no adequate remedy at law and that the Protected Parties shall be entitled to seek equitable relief, including specific performance and injunctive relief as remedies for any such breach or threatened or attempted breach, without requiring the posting of a bond. You hereby consent to the grant of an injunction (temporary or otherwise) against you or the entry of any other court order against you prohibiting and

6

enjoining you from violating, or directing you to comply with, any provision of the above paragraphs of this Letter Agreement, if such is determined by a court of competent jurisdiction. You also agree that such remedies shall be in addition to any and all other remedies, including damages, available to the Protected Parties against you for such breaches or threatened or attempted breaches.

         The Company agrees, to the extent permitted by applicable law and its organizational documents, to indemnify, defend and hold you harmless from and against any and all losses, suits, actions, causes of action, judgments, damages, liabilities, penalties, fines, costs or claims of any kind or nature (“Indemnified Claim”), including reasonable legal fees and related costs incurred by you in connection with the preparation for or defense of any Indemnified Claim, whether or not resulting in any liability, to which you may become subject or liable or which may be incurred by or assessed against you, relating to or arising out of your employment by the Company or the services to be performed pursuant to this Letter Agreement. The Company’s obligations under this paragraph shall be in addition to any other right, remedy or indemnification that you may have or be entitled to at common law or otherwise. For a period of 6 years after the Termination Date, the Company agrees to continue and maintain a directors and officers’ liability insurance policy covering you to the extent and in no less amount than the Company provides such coverage on the Termination Date for its managers, directors and/or other executive officers.

         Any notice or other communication required or which may be given hereunder shall be in writing and shall be delivered personally, including by courier service with receipt acknowledged in writing, emailed, sent by facsimile transmission or sent by certified or registered mail, postage prepaid and return receipt requested and shall be deemed to have been delivered on the date of delivery, the date of emailing or other facsimile transmission, or on the third business day after the date of mailing, addressed as follows (or to such other address as the party entitled to notice shall hereafter designate in accordance with the terms hereof):

If to you, to your home address reflected in the Company’s records.

         This Letter Agreement contains the entire agreement between you and the Company with respect to the subject matter hereof and supersedes all prior agreements, written or oral, with respect to such subject matter. For the sake of clarity, nothing in this paragraph is intended to negate or otherwise adversely affect your rights under compensation and benefit programs at the Company including, without limitation, the Deferred Stock Units.

         You represent and warrant that you are not a party to or subject to any restrictive covenants, legal restrictions or other agreements in favor of any entity or person which would in any way preclude, inhibit, impair or limit your ability to perform your obligations under this Letter Agreement, including, but not limited to, non-competition agreements, non-solicitation agreements or confidentiality agreements. The Company represents and warrants that it is fully authorized and empowered to enter into this Letter Agreement and that the performance of its obligations under this Letter Agreement will not violate any agreement between it and any other person, firm or organization.

         This Letter Agreement may be amended, modified, superseded, canceled, renewed or extended, and the terms and conditions hereof may be waived, only by a written instrument signed by both you and the Company. No delay on the part of either party in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any waiver on the part of any right, power or privilege hereunder, nor any single or partial exercise of any right, power or privilege hereunder, preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder.

8

         This Letter Agreement, except to the extent superseded by Federal law, shall be governed and construed in accordance with the laws of the State of New York applicable to agreements made and not to be performed entirely within such state, without regard to conflicts of law principles.

         We both agree irrevocably to submit to the exclusive jurisdiction of the Federal courts or, if no Federal jurisdiction exists, the state courts, located in the City of New York, Borough of Manhattan, for the purposes of any suit, action or other proceeding brought by any party arising out of any breach of any of the provisions of this Letter Agreement and hereby waive, and agree not to assert by way of motion, as a defense or otherwise, in any such suit, action, or proceeding, any claim that it is not personally subject to the jurisdiction of the above-named courts, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper, or that the provisions of this Letter Agreement may not be enforced in or by such courts. In addition, we both agree to waive trial by jury.

        This Letter Agreement, and the rights and obligations hereunder, may not be assigned by the Company or by you without written consent signed by the other party, provided that the Company may assign this Letter Agreement to any successor that continues all, or substantially all, the business of the Company.

         This Letter Agreement may be executed in counterparts, each of which shall be deemed an original but all of which shall constitute one and the same instrument.

         If any term, provision, covenant or restriction of this Letter Agreement, or any part thereof, is held by a court of competent jurisdiction of any foreign, federal, state, county or local government or any other governmental, regulatory or administrative agency or authority to be invalid, void, unenforceable or against public policy for any reason, the remainder of the terms, provisions, covenants and restrictions of this Letter Agreement shall remain in full force and effect and shall in no way be affected or impaired or invalidated. You acknowledge that the restrictive covenants contained in this Letter Agreement are a condition of this Letter Agreement and are reasonable and valid in temporal scope and in all other respects. For the sake of clarity, if any court determines that any of the restrictive covenants contained in this Letter Agreement, or any part of any of them, is invalid or unenforceable, the remainder of such covenants and parts thereof shall not

9

thereby be affected and shall be given full effect, without regard to the invalid portion. If any court determines that any of such covenants, or any part thereof, is invalid or unenforceable because of the geographic or temporal scope of such provision, such court shall reduce such scope to the minimum extent necessary to make such covenants valid and enforceable.

         The Company or other payor is authorized to withhold from any benefit provided or payment due hereunder, the amount of withholding taxes due any federal, state or local authority in respect of such benefit or payment and to take such other action as may be necessary in the opinion of the Company to satisfy all obligations for the payment of such withholding taxes.

         Notwithstanding any other provision of this Letter Agreement, if at the time of the termination your employment you are a “specified employee” (as defined in Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”)) and any payments under this Letter Agreement will result in additional tax or interest to you under Section 409A, you will not be entitled to receive such payments until the date which is six (6) months after the termination of your employment for any reason, other than as a result of your death or disability (as such term is defined in Section 409A). In addition, if any provision of this Letter Agreement would subject you to any additional tax or interest under Section 409A, then the Company shall reform such provision; provided that the Company shall (x) maintain, to the maximum extent practicable, the original intent of the applicable provision without subjecting you to such additional tax or interest and (y) not incur any additional compensation expense as a result of such reformation.

You shall be an independent contractor of the Company and shall have no authority (and shall not hold yourself out as having authority) to bind the Company and shall not make any agreements or representations on the Company’s behalf without the Company’s prior written consent. You shall be issued a tax form 1099 by the Company which reflects the applicable amount of any taxable payments in respect of your consulting services hereunder. There shall be no withholding or deduction from any amounts payable for such services, and you shall be solely responsible for, and indemnify and hold the Company harmless in respect of, the payment of any federal, state, local or other income, payroll and/or employment taxes. You agree, upon the request of the Company, to provide any reasonable assistance to the Company that may be required of it to demonstrate to a

10

Government Authority that your services under this Letter Agreement qualified as services by an independent contractor and all appropriate taxes with respect to any amounts paid hereunder (including but not limited to self-employment and income tax payments) have been paid.

(a) During 2013 and 2012, certain disposal groups met the criteria to be presented as discontinued operations. For all periods presented, the operating results for these operations have been removed from continuing operations. We report these businesses separately as discontinued operations in the Condensed Consolidated Financial Statements. Refer to Note 2 to the Condensed Consolidated Financial Statements for further discussion of our discontinued operations. All reported periods of the calculation of the ratio of earnings to fixed charges exclude discontinued operations.

(b) Amount for 2013 includes a $240 million reduction to retained earnings (accumulated deficit) related to a repurchase of mandatorily convertible preferred stock held by U.S. Department of Treasury and elimination of share adjustment right on November 20, 2013. Amount for 2010 includes a $616 million reduction to retained earnings (accumulated deficit) related to a conversion of preferred stock and related amendment that occurred on December 30, 2010.

(c) The ratio indicates a less than one-to-one coverage for the years ended December 31, 2011 and 2010. Earnings available for fixed charges for the years ended December 31, 2011 and 2010 were inadequate to cover fixed charges. The deficient amounts for the ratio were $183 million and $244 million for the years ended December 31, 2011 and 2010, respectively.

(d) The ratio indicates a less than one-to-one coverage for the years ended December 31, 2013, 2012, 2011, and 2010. Earnings available for fixed charges and preferred dividend requirements for the years ended December 31, 2013, 2012, 2011, and 2010 were inadequate to cover total fixed charges and preferred dividend requirements. The deficient amounts for the ratio were $708 million, $292 million, $946 million, and $2,104 million for the years ended December 31, 2013, 2012, 2011, and 2010, respectively.

Schedule of Unrealized Loss on Investments [Table Text Block]

The table below summarizes available-for-sale securities in an unrealized loss position in accumulated other comprehensive income. Based on the methodology that was applied to these securities, we believe that the unrealized losses relate to factors other than credit losses in the current market environment. As of March 31, 2015, we did not have the intent to sell the debt securities with an unrealized loss position in accumulated other comprehensive income, and it is not more likely than not that we will be required to sell these securities before recovery of their amortized cost basis. As of March 31, 2015, we had the ability and intent to hold equity securities with an unrealized loss position in accumulated other comprehensive income, and it is not more likely than not that we will be required to sell these securities before recovery of their amortized cost basis. As a result, we believe that the securities with an unrealized loss position in accumulated other comprehensive income are not considered to be other-than-temporarily impaired at March 31, 2015. Refer to Note 1 to the Consolidated Financial Statements in our 2014 Annual Report on Form 10-K for additional information related to investment securities and our methodology for evaluating potential other-than-temporary impairments.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Fair Value Amounts of Derivative Instruments Reported On Our Condensed Consolidated Balance Sheet [Table Text Block]

The following table summarizes the fair value amounts of derivative instruments reported on our Condensed Consolidated Balance Sheet. The fair value amounts are presented on a gross basis, are segregated by derivatives that are designated and qualifying as hedging instruments or those that are not, and are further segregated by type of contract within those two categories. Notional amounts are reference amounts from which contractual obligations are derived and are not recorded on the balance sheet. In our view, derivative notional is not an accurate measure of our derivative exposure when viewed in isolation from other factors, such as market rate fluctuations and counterparty credit risk.

Fair Value Disclosures [Abstract]

Fair Value Measurements - Recurring Basis [Table Text Block]

The following tables display the assets and liabilities measured at fair value on a recurring basis including financial instruments elected for the fair value option. We often economically hedge the fair value change of our assets or liabilities with derivatives and other financial instruments. The tables below display the hedges separately from the hedged items; therefore, they do not directly display the impact of our risk management activities.

The following table presents quantitative information regarding the significant unobservable inputs used in significant Level 3 assets measured at fair value on a nonrecurring basis.

Fair Value of Financial Intruments [Table Text Block]

The following table presents the carrying and estimated fair value of financial instruments, except for those recorded at fair value on a recurring basis presented in the previous section of this note titled Recurring Fair Value. When possible, we use quoted market prices to determine fair value. Where quoted market prices are not available, the fair value is internally derived based on appropriate valuation methodologies with respect to the amount and timing of future cash flows and estimated discount rates. However, considerable judgment is required in interpreting market data to develop estimates of fair value, so the estimates are not necessarily indicative of the amounts that could be realized or would be paid in a current market exchange. The effect of using different market assumptions or estimation methodologies could be material to the estimated fair values. Fair value information presented herein was based on information available at March 31, 2015 and December 31, 2014.

Regulatory Capital Requirements [Abstract]

Regulatory Capital Requirements under Banking Regulations [Text Block]

Regulatory Capital and Other Regulatory Matters

As a BHC, we and our wholly-owned state-chartered banking subsidiary, Ally Bank, are subject to capital requirements issued by U.S. banking regulators that require us to maintain risk-based and leverage capital ratios above minimum levels. A risk-based capital ratio is a ratio of a banking organization’s regulatory capital to its risk-weighted assets. A leverage capital ratio is a ratio of a banking organization’s regulatory capital to a measure of assets or exposures that is not risk-weighted. As of January 1, 2015, Ally and Ally Bank became subject to the rules implementing the 2010 Basel III capital framework in the United States (U.S. Basel III), which reflect new and higher capital requirements, capital buffers, and new regulatory capital definitions, deductions and adjustments. Certain aspects of U.S. Basel III, including the new capital buffers and regulatory capital deductions, will be phased in over several years.

Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary action by regulators that, if undertaken, could have a direct material effect on the Condensed Consolidated Financial Statements or the results of operations and financial condition of Ally and Ally Bank. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, we must meet specific capital guidelines that involve quantitative measures of our capital, assets and certain off-balance sheet items. These measures and related classifications, which are used in our risk-based and leverage capital ratios, are also subject to qualitative judgments by the regulators about the components of capital, the risk-weightings of our assets and other exposures, and other factors. The U.S. banking regulators also use these ratios and guidelines as part of the capital planning and stress testing processes. In addition, in order for Ally to maintain its status as a FHC, Ally and its bank subsidiary, Ally Bank, must remain “well-capitalized” and “well-managed,” as defined under applicable law. Effective January 1, 2015, the “well-capitalized” standard for insured depository institutions, such as Ally Bank, was revised to reflect the new and higher capital requirements under U.S. Basel III.

Under U.S. Basel III, Ally must maintain a minimum Common Equity Tier 1 risk-based capital ratio of 4.5%, a minimum Tier 1 risk-based capital ratio of 6%, and a minimum Total risk-based capital ratio of 8%. In addition to these minimum requirements, Ally will also be subject to a Common Equity Tier 1 capital conservation buffer of more than 2.5%, subject to a phase-in period from January 1, 2016 through December 31, 2018. Failure to maintain the full amount of the buffer will result in restrictions on Ally’s ability to make capital distributions, including dividend payment and stock repurchases and redemptions, and to pay discretionary bonuses to executive officers. In addition to these new risk-based capital standards, U.S. Basel III subjects all U.S. banking organizations, including Ally, to a minimum Tier 1 leverage ratio of 4%, the denominator of which takes into account only on-balance sheet assets.

In addition to introducing new capital ratios, U.S. Basel III revises the eligibility criteria for regulatory capital instruments and provides for the phase-out of existing capital instruments that do not satisfy the new criteria. Subject to certain exceptions (e.g., for certain debt or equity issued to the U.S. government under the Emergency Economic Stabilization Act), trust preferred and other “hybrid” securities will be phased out from a banking organization’s Tier 1 capital by January 1, 2016. Also, subject to a phase-in schedule, certain new items will be deducted from Common Equity Tier 1 capital, and certain other deductions from regulatory capital will be modified. Among other things, U.S. Basel III requires significant investments in the common shares of unconsolidated financial institutions, mortgage servicing rights, and certain deferred tax assets that exceed specified individual and aggregate thresholds to be deducted from Common Equity Tier 1 capital. U.S. Basel III also revises the standardized approach for calculating risk-weighted assets by, among other things, modifying certain risk weights and introducing new methods for calculating risk-weighted assets for certain types of assets and exposures.

Ally is subject to the U.S. Basel III standardized approach for counterparty credit risk. It is not subject to the U.S. Basel III advanced approaches for counterparty credit risk. Ally is currently not subject to the U.S. market risk capital rule, which applies only to banking organizations with significant trading assets and liabilities.

During 2010, Ally, IB Finance Holding Company, LLC (IB Finance), Ally Bank, and the Federal Deposit Insurance Corporation (FDIC) entered into a Capital and Liquidity Maintenance Agreement (CLMA). The effective date of the CLMA was August 24, 2010. The CLMA requires capital at Ally Bank to be maintained at a level such that Ally Bank's leverage ratio is at least 15%. For this purpose, the leverage ratio is determined in accordance with the FDIC's regulations related to capital maintenance.

The following table summarizes our capital ratios under the U.S. Basel III capital framework.

	Under Basel III				Under Basel I
	March 31, 2015 (a)				December 31, 2014 (b)				Required minimum			Well-capitalized minimum
($ in millions)	Amount		Ratio		Amount		Ratio
Risk-based capital
Common Equity Tier 1 (to risk-weighted assets) (c)
Ally Financial Inc.	$	14,240	10.94	%	$	12,588	9.64	%	4.50	%		(d)

Total (to risk-weighted assets)
Ally Financial Inc.	$	18,365	14.11	%	$	17,294	13.24	%	8.00	%		(d)
Ally Bank	16,574		17.91		16,468		17.36		8.00			10.00	%

Ally Financial Inc.	$	17,131	11.43	%	$	16,389	10.94	%	4.00	%		(d)
Ally Bank	16,185		15.61		16,022		15.44		15.00		(f)	5.00	%

(a) U.S. Basel III became effective for us on January 1, 2015, subject to transitional provisions primarily related to deductions and adjustments impacting Common Equity Tier 1 capital and Tier 1 capital.

(b) Capital ratios as of December 31, 2014 are presented under the U.S. Basel I capital framework.

(c) Previously referred to as Tier 1 Common Equity under the U.S. Basel I capital framework.

(d) U.S. Basel III does not establish standards for determining whether a BHC is "well-capitalized."

(e) Federal regulatory reporting guidelines require the calculation of adjusted quarterly average assets using a daily average methodology.

(f) Ally Bank, in accordance with the CLMA, is required to maintain a Tier 1 leverage ratio of at least 15%.

At March 31, 2015, Ally and Ally Bank were “well-capitalized” and met all capital requirements to which each was subject.

Capital Planning and Stress Tests

As a BHC with $50 billion or more of consolidated assets, Ally is required to conduct periodic internal stress tests, is subject to an annual supervisory stress test conducted by the Board of Governors of the Federal Reserve System (FRB), and must submit an annual capital plan to the FRB. Ally’s capital plan must include a description of all planned capital actions over a nine-quarter planning horizon. The capital plan must also include a discussion of how Ally will maintain capital above the minimum regulatory capital ratios and above a Tier 1 common equity-to-total risk-weighted assets ratio of 5% under baseline, adverse, and severely adverse economic scenarios, and serve as a source of strength to Ally Bank. The FRB must approve Ally's capital plan before Ally may take any capital action. Even with an approved capital plan, Ally must seek the approval of the FRB before making a capital distribution if, among other factors, Ally would not meet its regulatory capital requirements after making the proposed capital distribution.

On January 5, 2015, Ally Financial Inc. submitted the results of its semi-annual stress test and its proposed capital actions to the FRB, and Ally Bank submitted the results of its annual company-run stress test to the FDIC. On March 6, 2015, Ally Financial Inc. and Ally Bank publicly disclosed summary results of the stress test under the most severe scenario in accordance with regulatory requirements. On March 11, 2015, Ally received a non-objection to its capital plan from the FRB, including the proposed capital actions contained in its submission.

Offsetting [Abstract]

Assets and Liabilities Subject to Enforceable Master Netting Arrangements [Text Block]

Offsetting Assets and Liabilities

Our qualifying master netting agreements are written, legally enforceable bilateral agreements that (1) create a single legal obligation for all individual transactions covered by the agreement to the non-defaulting entity upon an event of default of the counterparty, including bankruptcy, insolvency, or similar proceeding, and (2) provide the non-defaulting entity the right to accelerate, terminate, and close-out on a net basis all transactions under the agreement and to liquidate or set off collateral promptly upon an event of default of the counterparty. In certain instances we have the option to report financial instruments that are subject to a qualifying master netting agreement on a net basis. However, we have elected to report these instruments as gross assets and liabilities on the Condensed Consolidated Balance Sheet.

To further mitigate the risk of counterparty default related to derivative instruments, we maintain collateral agreements with certain counterparties. The agreements require both parties to maintain collateral in the event the fair values of the derivative financial instruments meet established thresholds. In the event that either party defaults on the obligation, the secured party may seize the collateral. Generally, our collateral arrangements are bilateral such that we and the counterparty post collateral for the value of our total obligation to each other. Contractual terms provide for standard and customary exchange of collateral based on changes in the market value of the outstanding derivatives. The securing party posts additional collateral when their obligation rises or removes collateral when it falls, such that the net replacement cost of the non-defaulting party is covered in the event of counterparty default.

The composition of offsetting derivative instruments, financial assets, and financial liabilities was as follows.

	Gross Amounts of Recognized Assets/(Liabilities)			Gross Amounts Offset in the Condensed Consolidated Balance Sheet		Net Amounts of Assets/(Liabilities) Presented in the Condensed Consolidated Balance Sheet

Fair Value Disclosures [Abstract]

Fair Value Disclosures [Text Block]

Fair Value

Fair Value Measurements

For purposes of this disclosure, fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability (exit price) in the principal or most advantageous market in an orderly transaction between market participants at the measurement date. Fair value is based on the assumptions market participants would use when pricing an asset or liability. Additionally, entities are required to consider all aspects of nonperformance risk, including the entity’s own credit standing, when measuring the fair value of a liability.

GAAP specifies a three-level hierarchy that is used when measuring and disclosing fair value. The fair value hierarchy gives the highest priority to quoted prices available in active markets (i.e., observable inputs) and the lowest priority to data lacking transparency (i.e., unobservable inputs). An instrument’s categorization within the fair value hierarchy is based on the lowest level of significant input to its valuation. The following is a description of the three hierarchy levels.

Level 1 Inputs are quoted prices in active markets for identical assets or liabilities at the measurement date. Additionally, the entity must have the ability to access the active market, and the quoted prices cannot be adjusted by the entity.

Level 2 Inputs are other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices in active markets for similar assets or liabilities; quoted prices in inactive markets for identical or similar assets or liabilities; or inputs that are observable or can be corroborated by observable market data by correlation or other means for substantially the full term of the assets or liabilities.

Level 3 Unobservable inputs are supported by little or no market activity. The unobservable inputs represent management's best assumptions of how market participants would price the assets or liabilities. Generally, Level 3 assets and liabilities are valued using pricing models, discounted cash flow methodologies, or similar techniques that require significant judgment or estimation.

Transfers Transfers into or out of any hierarchy level are recognized at the end of the reporting period in which the transfer occurred. There were no transfers between any levels during the three months endedMarch 31, 2015.

Following are descriptions of the valuation methodologies used to measure material assets and liabilities at fair value and details of the valuation models, key inputs to those models, and significant assumptions utilized.

• Available-for-sale securities — All classes of available-for-sale securities are carried at fair value based on observable market prices, when available. If observable market prices are not available, our valuations are based on internally developed discounted cash flow models (an income approach) that use a market-based discount rate and consider recent market transactions, experience with similar securities, current business conditions, and analysis of the underlying collateral, as available. To estimate cash flows, we are required to utilize various significant assumptions including market observable inputs (e.g., forward interest rates) and internally developed inputs (including prepayment speeds, delinquency levels, and credit losses).

• Automotive loans held-for-sale, net — Our automotive loans held-for-sale are accounted for at the lower-of-cost or fair value. The automotive loans at fair value are presented in the nonrecurring fair value measurement table. We based our valuation of automotive loans held-for-sale on internally developed discounted cash flow models (an income approach) and classified all these loans as Level 3. These valuation models estimate the exit price we expect to receive in the loan’s principal market, which, depending on characteristics of the loans, may be the whole-loan market or the securitization market. Although we utilize and give priority to market observable inputs, such as interest rates and market spreads within these models, we are typically required to utilize internal inputs, such as prepayment speeds (absolute prepayment model, or ABS), gross loss range by loan segment (percentage of receivable balance lost in the event of default), and credit spreads (the risk premium component added to observed benchmark rate to determine the discount rate used in the discounted cash flow model). While numerous controls exist to calibrate, corroborate, and validate these internal inputs, these internal inputs require the use of judgment and can have a significant impact on the determination of the loan’s value. Accordingly, we classified all automotive loans held-for-sale as Level 3.

• Mortgage loans held-for-sale, net — Certain of our mortgage loans held-for-sale are accounted for at fair value because of fair value option elections. Mortgage loans held-for-sale are typically pooled together and sold into certain exit markets depending on underlying attributes of the loan, such as eligibility with the Federal National Mortgage Association (Fannie Mae), the Federal Home Loan Mortgage Corporation (Freddie Mac), or the Government National Mortgage Association (Ginnie Mae) (collectively, the Government-sponsored Enterprises, or GSEs), product type, interest rate, and credit quality. Mortgage loans previously classified as Level 2 were mainly GSE-eligible mortgage loans carried at fair value due to fair value option election, which were valued predominantly using published forward agency prices. It also included any domestic loans where recently negotiated market prices for the loan pool exist with a counterparty (which approximates fair value) or quoted market prices for similar loans are available. These mortgage loans were transferred into Level 3 as of December 31, 2014 based on decreased observability of significant inputs resulting from no longer being an active seller of mortgage loans to GSEs. As a result, they are now valued based on a discounted cash flow basis utilizing cash flow projections from internally developed models that utilized prepayment, default, and discount rate assumptions.

Refer to the section within this note titled Fair Value Option for Financial Assets and Financial Liabilities for further information about the fair value elections.

• Interests retained in financial asset sales — The interests retained are in securitization trusts and deferred purchase prices on the sale of whole-loans. Due to inactivity in the market, valuations are based on internally developed discounted cash flow models (an income approach) that use a market-based discount rate; therefore, we classified these assets as Level 3. The valuation considers recent market transactions, experience with similar assets, current business conditions, and analysis of the underlying collateral, as available. To estimate cash flows, we utilize various significant assumptions, including market observable inputs (e.g., forward interest rates) and internally developed inputs (e.g., prepayment speeds, delinquency levels, and credit losses).

• Derivative instruments — We enter into a variety of derivative financial instruments as part of our risk management strategies. Certain of these derivatives are exchange traded, such as Eurodollar futures, options of Eurodollar futures, and equity options. To determine the fair value of these instruments, we utilize the quoted market prices for the particular derivative contracts; therefore, we classified these contracts as Level 1.

We also execute over-the-counter (OTC) and centrally-cleared derivative contracts, such as interest rate swaps, a cross-currency swap, swaptions, foreign-currency denominated forward contracts, prepaid equity forward contracts, caps, floors, and agency to-be-announced securities. For OTC contracts, we utilize third-party-developed valuation models that are widely accepted in the market to value these OTC derivative contracts. The specific terms of the contract and market observable inputs (such as interest rate forward curves, interpolated volatility assumptions, or equity pricing) are used in the model. We classified these OTC derivative contracts as Level 2 because all significant inputs into these models were market observable. For centrally-cleared contracts, we utilize unadjusted prices obtained from the clearing house as the basis for valuation, and they are also classified as Level 2. During 2014, we began to value our bilateral interest rate swap and interest rate cap portfolio using Overnight Index Swap discount curves. We previously valued this portfolio using London Interbank Offered Rate (LIBOR) discount curves. Because we continued to use a third-party-developed valuation model in which all significant inputs were market observable, these contracts remained classified as Level 2.

Historically, we had a cross-currency swap and interest rate caps accounted for as derivative instruments that were classified as Level 3. However, at March 31, 2015 and December 31, 2014, we did not have any positions classified as Level 3.

We are required to consider all aspects of nonperformance risk, including our own credit standing, when measuring fair value of a liability. We reduce credit risk on the majority of our derivatives by entering into legally enforceable agreements that enable the posting and receiving of collateral associated with the fair value of our derivative positions on an ongoing basis. In the event that we do not enter into legally enforceable agreements that enable the posting and receiving of collateral, we will consider our credit risk and the credit risk of our counterparties in the valuation of derivative instruments through a credit valuation adjustment (CVA), if warranted. The CVA calculation utilizes the credit default swap spreads of the counterparty.

Recurring Fair Value

The following tables display the assets and liabilities measured at fair value on a recurring basis including financial instruments elected for the fair value option. We often economically hedge the fair value change of our assets or liabilities with derivatives and other financial instruments. The tables below display the hedges separately from the hedged items; therefore, they do not directly display the impact of our risk management activities.

Nonrecurring Fair Value

We may be required to measure certain assets and liabilities at fair value from time to time. These periodic fair value measures typically result from the application of lower-of-cost or fair value accounting or certain impairment measures. These items would constitute nonrecurring fair value measures.

The following tables display the assets and liabilities measured at fair value on a nonrecurring basis.

Accordingly, the table above excludes total gains and losses included in earnings for these items. The carrying values are inclusive of the respective valuation or loan loss allowance.

(b) Represents the portion of the portfolio specifically impaired during 2015. The related valuation allowance represents the cumulative adjustment to fair value of those specific receivables.

(c) The allowance provided for repossessed and foreclosed assets represents any cumulative valuation adjustment recognized to adjust the assets to fair value.

The following table presents quantitative information regarding the significant unobservable inputs used in significant Level 3 assets measured at fair value on a nonrecurring basis.

				Gross loss	0-4.80%
				Credit spread	0.58%

Fair Value Option for Financial Assets

We elected the fair value option for an insignificant amount of conforming and government-insured mortgage loans held-for-sale. We elected the fair value option to mitigate earnings volatility by better matching the accounting for the assets with the related hedges. Our intent in electing fair value measurement was to mitigate a divergence between accounting losses and economic exposure for certain assets and liabilities.

Fair Value of Financial Instruments

The following table presents the carrying and estimated fair value of financial instruments, except for those recorded at fair value on a recurring basis presented in the previous section of this note titled Recurring Fair Value. When possible, we use quoted market prices to determine fair value. Where quoted market prices are not available, the fair value is internally derived based on appropriate valuation methodologies with respect to the amount and timing of future cash flows and estimated discount rates. However, considerable judgment is required in interpreting market data to develop estimates of fair value, so the estimates are not necessarily indicative of the amounts that could be realized or would be paid in a current market exchange. The effect of using different market assumptions or estimation methodologies could be material to the estimated fair values. Fair value information presented herein was based on information available at March 31, 2015 and December 31, 2014.

The following describes the methodologies and assumptions used to determine fair value for the significant classes of financial instruments. In addition to the valuation methods discussed below, we also followed guidelines for determining whether a market was not active and a transaction was not distressed. As such, we assumed the price that would be received in an orderly transaction (including a market-based return) and not in forced liquidation or distressed sale.

• Cash and cash equivalents — Included in cash and cash equivalents are highly liquid investments that are readily convertible to known amounts of cash and which are subject to an insignificant risk of change in value due to interest rate, quoted price, or penalty on withdrawal. Classified as Level 1 under the fair value hierarchy, cash and cash equivalents generally expose us to limited credit risk and have no stated maturities or have short-term maturities and carry interest rates that approximate market. As such, the carrying value approximates the fair value of these instruments.

• Loans held-for-sale, net — Loans held-for-sale classified as Level 3 include all loans valued using internally developed valuation models because observable market prices were not available. We based our valuation of automotive loans held-for-sale on internally developed discounted cash flow models (an income approach). These valuation models estimate the exit price we expect to receive in the loan’s principal market, which, depending on characteristics of the loans, may be the whole-loan market or the securitization market. Although we utilize and give priority to market observable inputs, such as interest rates and market spreads within these models, we are typically required to utilize internal inputs, such as prepayment speeds (absolute prepayment model, or ABS), gross loss range by loan segment (percentage of receivable balance lost in the event of default), and credit spreads (the risk premium component added to observed benchmark rate to determine the discount rate used in the discounted cash flow model). While numerous controls exist to calibrate, corroborate, and validate these internal inputs, these internal inputs require the use of judgment and can have a significant impact on the determination of the loan’s value. Accordingly, we classified all automotive loans held-for-sale as Level 3. Loans held-for-sale classified as Level 2 as of December 31, 2014 represent mortgage TDR loans valued using quoted prices in active markets for similar assets.

• Finance receivables and loans, net — With the exception of mortgage loans held-for-investment, the fair value of finance receivables and loans was based on discounted future cash flows using applicable spreads to approximate current rates applicable to each category of finance receivables and loans (an income approach using Level 3 inputs). The carrying value of commercial receivables in certain markets and certain automotive and other receivables for which interest rates reset on a short-term basis with applicable market indices are assumed to approximate fair value either because of the short-term nature or because of the interest rate adjustment feature. The fair value of commercial receivables in other markets was based on discounted future cash flows using applicable spreads to approximate current rates applicable to similar assets in those markets.

For consumer mortgage loans, we used valuation methods and assumptions similar to those used for mortgage loans held-for-sale. These valuations consider unique attributes of the loans such as geography, delinquency status, product type, and other factors. Refer to the section above titled Loans held-for-sale, net, for a description of methodologies and assumptions used to determine the fair value of mortgage loans held-for-sale.

• Deposit liabilities — Deposit liabilities represent certain consumer and brokered bank deposits, mortgage escrow deposits, and dealer deposits. The fair value of deposits at Level 3 were estimated by discounting projected cash flows based on discount factors derived from the forward interest rate swap curve.

• Short-term borrowings and Long-term debt — Level 2 debt was valued using quoted market prices for similar instruments, when available, or other means for substantiation with observable inputs. Debt valued using internally derived inputs, such as prepayment speeds and discount rates, was classified as Level 3.

Segment Reporting [Abstract]

Segment Reporting Disclosure [Text Block]

Segment and Geographic Information

Operating segments are defined as components of an enterprise that engage in business activity from which revenues are earned and expenses incurred for which discrete financial information is available that is evaluated regularly by our chief operating decision maker in deciding how to allocate resources and in assessing performance.

We report our results of operations on a line-of-business basis through three operating segments: Automotive Finance operations, Insurance operations, and Mortgage operations, with the remaining activity reported in Corporate and Other. The operating segments are determined based on the products and services offered, and reflect the manner in which financial information is currently evaluated by management. The following is a description of each of our reportable operating segments.

Automotive Finance operations— Provides automotive financing services to consumers and automotive dealers. Our automotive financing services include providing retail installment sales financing, loans, and leases; offering term loans to dealers, financing dealer floorplans and other lines of credit to dealers; fleet financing, and vehicle remarketing services.

Insurance operations — Offers both consumer financial and insurance products sold primarily through the automotive dealer channel, and commercial insurance products sold to dealers. As part of our focus on offering dealers a broad range of consumer financial and insurance products, we provide vehicle service contracts, maintenance coverage, and guaranteed automobile protection (GAP) products. We also underwrite selected commercial insurance coverages, which primarily insure dealers' vehicle inventories.

Mortgage operations — Our ongoing Mortgage operations include the management of our held-for-investment and held-for-sale mortgage portfolios.

Corporate and Other primarily consists of Corporate Finance, centralized corporate treasury activities, such as management of the cash and corporate investment securities portfolios, short- and long-term debt, retail and brokered deposit liabilities, derivative instruments, the amortization of the discount associated with debt issuances and bond exchanges, and the residual impacts of our corporate funds-transfer pricing (FTP) and treasury asset liability management (ALM) activities. Corporate and Other also includes certain equity investments, overhead that was previously allocated to operations that have since been sold or classified as discontinued operations, and reclassifications and eliminations between the reportable operating segments.

We utilize an FTP methodology for the majority of our business operations. The FTP methodology assigns charge rates and credit rates to classes of assets and liabilities based on expected duration and the LIBOR swap curve plus an assumed credit spread. Matching duration allocates interest income and interest expense to these reportable segments so their respective results are insulated from interest rate risk. This methodology is consistent with our ALM practices, which includes managing interest rate risk centrally at a corporate level. The net residual impact of the FTP methodology is included within the results of Corporate and Other.

The information presented in our reportable operating segments and geographic areas tables that follow are based in part on internal allocations, which involve management judgment.

Financial information for our reportable operating segments is summarized as follows.

Parent and Guarantor Condensed Consolidating Financial Statements

Certain of our senior notes issued by the parent are guaranteed by 100% directly owned subsidiaries of Ally (the Guarantors). As of March 31, 2015, the Guarantors include Ally US LLC and IB Finance, each of which fully and unconditionally guarantee the senior notes on a joint and several basis.

The following financial statements present condensed consolidating financial data for (i) Ally Financial Inc. (on a parent company-only basis); (ii) the Guarantors; (iii) the nonguarantor subsidiaries (all other subsidiaries); and (iv) an elimination column for adjustments to arrive at (v) the information for the parent company, the Guarantors, and nonguarantors on a consolidated basis.

Investments in subsidiaries are accounted for by the parent company and the Guarantors using the equity-method for this presentation. Results of operations of subsidiaries are therefore classified in the parent company’s and Guarantors’ investment in subsidiaries accounts. The elimination entries set forth in the following condensed consolidating financial statements eliminate distributed and undistributed income of subsidiaries, investments in subsidiaries, and intercompany balances and transactions between the parent, the Guarantors, and nonguarantors.

Discontinued and Held-for-sale Operations

Discontinued Operations

Prior to the adoption of ASU 2014-08, which is to be prospectively applied only to newly identified disposals that qualify as discontinued operations beginning after January 1, 2015, we have classified operations as discontinued when operations and cash flows will be eliminated from our ongoing operations and we do not expect to retain any significant continuing involvement in their operations after the respective sale or disposal transactions. For all periods presented, the operating results for these discontinued operations have been removed from continuing operations and presented separately as discontinued operations, net of tax, in the Condensed Consolidated Statement of Comprehensive Income. The Notes to the Condensed Consolidated Financial Statements have been adjusted to exclude discontinued operations unless otherwise noted.

Select Automotive Finance Operations

During the fourth quarter of 2012, we committed to sell our automotive finance operations in Europe and Latin America to General Motors Financial Company, Inc. (GMF). On the same date, we entered into an agreement with GMF to sell our 40% interest in a motor vehicle finance joint venture in China. During the second quarter of 2013, we completed the sale of our operations in Europe and the majority of Latin America. The transaction included European operations in Germany, the United Kingdom, Italy, Sweden, Switzerland, Austria, Belgium, France and the Netherlands, and Latin America operations in Mexico, Chile, and Colombia. During the fourth quarter of 2013, we completed the sale of our Latin American operations in Brazil.

On January 2, 2015, the sale of our interest in the motor vehicle finance joint venture in China was completed and an after-tax gain of approximately $400 million was recorded. The tax expense included in this gain was reduced by the release of valuation allowance on our capital loss carryforward deferred tax asset that was utilized to offset capital gains stemming from this sale.

Other Operations

Other operations relate to previous discontinued operations for which we continue to have minimal residual costs.

Select Financial Information

Select financial information of discontinued operations is summarized below. The pretax income or loss, including direct costs to transact a sale, includes any impairment recognized to present the operations at the lower-of-cost or fair value. Fair value was based on the estimated sales price, which could differ from the ultimate sales price due to price volatility, changing interest rates, changing foreign-currency rates, and future economic conditions.

Contingencies And Other Risks

3 Months Ended

Mar. 31, 2015

Loss Contingency [Abstract]

Contingencies Disclosure and Other Risks [Text Block]

Contingencies and Other Risks

In the normal course of business, we enter into transactions that expose us to varying degrees of risk. For additional information on contingencies and other risks arising from such transactions, refer to Note 30 to the Consolidated Financial Statements in our 2014 Annual Report on Form 10-K.

Legal Proceedings

We are or may be subject to potential liability under various governmental proceedings, claims, and legal actions that are pending or otherwise asserted against us. We are named as defendants in a number of legal actions, and we are involved in governmental proceedings arising in connection with our respective businesses. Some of the pending actions purport to be class actions, and certain legal actions include claims for substantial compensatory and/or punitive damages or claims for indeterminate amounts of damages. We establish reserves for legal claims when payments associated with the claims become probable and the payments can be reasonably estimated. Given the inherent difficulty of predicting the outcome of litigation and regulatory matters, it is generally very difficult to predict what the eventual outcome will be, and when the matter will be resolved. The actual costs of resolving legal claims may be higher or lower than any amounts reserved for the claims.

On the basis of information currently available, advice of counsel, available insurance coverage, and established reserves, it is the opinion of management that the eventual outcome of the current actions against us will not have a material adverse effect on our consolidated financial condition, results of operations, or cash flows. However, it is possible that the ultimate resolution of legal matters, if unfavorable, may be material to our consolidated financial condition, results of operations, or cash flows in a particular period.

Regulatory Matters

Ally and its subsidiaries, including Ally Bank, are or may become involved from time to time in formal and informal reviews, investigations, examinations, proceedings, and information-gathering requests by federal and state government and self-regulatory agencies, including, among others, the U.S. Department of Justice (DOJ), SEC, Consumer Financial Protection Bureau (CFPB), the FRB, the FDIC, the Utah Department of Department of Financial Institutions, and the Federal Trade Commission regarding their respective operations.

Mortgage Matters

We have received subpoenas from the DOJ that include a broad request for documentation and other information relating to residential mortgage-backed securities issued by our former mortgage subsidiary, Residential Capital, LLC and its subsidiaries (ResCap RMBS). In connection with these requests, the DOJ is investigating potential fraud and other potential legal claims related to ResCap RMBS, including its investigation of potential claims under the Financial Institutions Reform, Recovery, and Enforcement Act of 1989. The DOJ is also investigating potential claims under the False Claims Act (FCA) related to representations made by us in connection with investments in Ally made by the United States Department of the Treasury pursuant to the Troubled Asset Relief Program in 2008 and 2009 regarding certain claims against Residential Capital, LLC or its subsidiaries at that time. We are engaged in ongoing discussions with the DOJ with respect to legal and factual aspects of their investigations. Further, at the request of the DOJ, we have entered into an agreement to voluntarily extend the statutes of limitations related to potential FCA claims.

We have separately received subpoenas and document requests from the SEC that include information covering a wide range of mortgage-related matters.

Automotive Subprime Matters

In October 2014 we received a document request from the SEC in connection with its investigation related to subprime automotive finance and related securitization activities. Separately, in December 2014, we received a subpoena from the DOJ requesting similar information. We are currently cooperating with both the SEC and DOJ with respect to these matters.

CFPB

In December 2013, Ally Financial Inc. and Ally Bank entered into Consent Orders issued by the CFPB and the DOJ pertaining to the allegation of disparate impact in the automotive finance business. The Consent Orders require Ally to create a compliance plan addressing, at a minimum, the communication of Ally’s expectations of Equal Credit Opportunity Act compliance to dealers, maintenance of Ally’s existing limits on dealer finance income for contracts acquired by Ally, and monitoring for potential discrimination both at the dealer level and within our portfolio of contracts acquired across all dealers. Ally formed a compliance committee consisting of certain Ally and Ally Bank directors to oversee Ally’s execution of the Consent Orders’ terms. Ally is required to meet certain stipulations under the Consent Orders, including a requirement to make monetary payments when ongoing remediation targets are not attained.

Each of the regulatory matters set forth above may result in material adverse consequences including without limitation, adverse judgments, significant settlements, fines, penalties, injunctions, or other actions.

Other Contingencies

We are subject to potential liability under various other exposures including tax, nonrecourse loans, self-insurance, and other miscellaneous contingencies. We establish reserves for these contingencies when the loss becomes probable and the amount can be reasonably estimated. The actual costs of resolving these items may be substantially higher or lower than the amounts reserved for any one item. Based on information currently available, it is the opinion of management that the eventual outcome of these items will not have a material adverse impact on our results of operations, financial position, or cash flows.

Discontinued Operations

Prior to the adoption of ASU 2014-08, which is to be prospectively applied only to newly identified disposals that qualify as discontinued operations beginning after January 1, 2015, we have classified operations as discontinued when operations and cash flows will be eliminated from our ongoing operations and we do not expect to retain any significant continuing involvement in their operations after the respective sale or disposal transactions. For all periods presented, the operating results for these discontinued operations have been removed from continuing operations and presented separately as discontinued operations, net of tax, in the Condensed Consolidated Statement of Comprehensive Income. The Notes to the Condensed Consolidated Financial Statements have been adjusted to exclude discontinued operations unless otherwise noted.

Description of Business, Basis of Presentation, and Changes in Significant Accounting Policies

Ally Financial Inc. (referred to herein as Ally, we, our, or us) is a leading, independent, diversified financial services firm. Founded in 1919, we are a leading financial services company with more than 95 years of experience providing a broad array of financial products and services, primarily to automotive dealers and retail customers. We operate as a financial holding company (FHC) and a bank holding company (BHC). Our banking subsidiary, Ally Bank, is an indirect, wholly-owned subsidiary of Ally Financial Inc. and a leading franchise in the growing direct (internet, telephone, mobile, and mail) banking market.

Our accounting and reporting policies conform to accounting principles generally accepted in the United States of America (GAAP). Additionally, where applicable, the policies conform to the accounting and reporting guidelines prescribed by bank regulatory authorities. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and that affect income and expenses during the reporting period and related disclosures. In developing the estimates and assumptions, management uses all available evidence; however, actual results could differ because of uncertainties associated with estimating the amounts, timing, and likelihood of possible outcomes.

The Condensed Consolidated Financial Statements at March 31, 2015, and for the three months endedMarch 31, 2015, and 2014, are unaudited but reflect all adjustments that are, in management’s opinion, necessary for the fair presentation of the results for the interim periods presented. All such adjustments are of a normal recurring nature. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements (and the related notes) included in our Annual Report on Form 10-K for the year ended December 31, 2014, as filed on February 27, 2015, with the U.S. Securities and Exchange Commission (SEC).

Significant Accounting Policies

Income Taxes

In calculating the provision for interim income taxes, in accordance with Accounting Standards Codification (ASC) 740, Income Taxes, we apply an estimated annual effective tax rate to year-to-date ordinary income. At the end of each interim period, we estimate the effective tax rate expected to be applicable for the full fiscal year. This method differs from that described in Note 1 to the Consolidated Financial Statements in our 2014 Annual Report on Form 10-K, which describes our annual significant income tax accounting policy and related methodology.

Refer to Note 1 to the Consolidated Financial Statements in our 2014 Annual Report on Form 10-K regarding additional significant accounting policies.

Recently Adopted Accounting Standards

Receivables — Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (ASU 2014-04)

As of January 1, 2015, we adopted ASU 2014-04. The amendments in this ASU clarify the timing for which an entity should reclassify a loan that has been foreclosed or where an in substance repossession has occurred to real estate owned. The guidance requires a reclassification to occur when the entity obtains legal title upon completion of foreclosure or the borrower conveys all interest in the residential real estate property to the entity to satisfy the loan through completion of a deed in lieu of foreclosure or similar legal agreement. In addition, the ASU clarifies that redemption rights of the borrower should be ignored for purposes of determining whether legal title has transferred. We adopted the guidance utilizing a modified retrospective approach. The adoption of this guidance did not have a material effect on our consolidated financial condition or results of operations.

Presentation of Financial Statements and Property, Plant, and Equipment — Reporting Discontinued Operations and Disclosure of Disposals of Components of an Entity (ASU 2014-08)

As of January 1, 2015, we adopted ASU 2014-08. The amendments in this ASU modify the requirements for the reporting of discontinued operations. In order to qualify as a discontinued operation, the disposal of a component of an entity, a group of components, or a business of an entity must represent a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. The ASU further indicates that the timing for recording a discontinued operation is when one of the following occurs: the component, group of components, or business meets the criteria to be classified as held-for-sale; the component, group of components, or business is disposed of by sale; or the component, group of components, or business is disposed of other than by sale (for example abandonment or spinoff). In addition, the ASU also requires additional disclosure items about an entity’s discontinued operations. The amendments were applied prospectively solely to newly identified disposals that qualify as discontinued operations after the effective date. Items previously reported as discontinued operations will maintain their classification based on the prior guidance. The adoption of this guidance did not have a material effect on our consolidated financial condition or results of operations.

Transfers and Servicing — Repurchase-to-Maturity Transactions, Repurchase Financings and Disclosures (ASU 2014-11)

As of January 1, 2015, we adopted ASU 2014-11. The amendments in this ASU change the accounting for repurchase-to-maturity transactions and repurchase financing transactions such that both will be reported as secured borrowings. In addition to the changes to how these transactions are reported, the ASU also includes new disclosure requirements. The amendments are effective for us beginning on January 1, 2015. The amendments were applied to all transactions that fall under the guidance as of the date of adoption with a cumulative effect adjustment recorded on the date of initial adoption. The adoption of this guidance did not have a material effect on our consolidated financial condition or results of operations.

Recently Issued Accounting Standards

Revenue from Contracts with Customers (ASU 2014-09)

In May 2014, the Financial Accounting Standards Board (FASB) issued ASU 2014-09. The purpose of this guidance is to streamline and consolidate existing revenue recognition principles in GAAP and to converge revenue recognition principles with International Financial Reporting Standards (IFRS). The core principle of the amendments is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to receive in exchange for those goods or services. The amendments include a five step process for consideration of the main principle, guidance on the accounting treatment for costs associated with a contract, and disclosure requirements related to the revenue process. The amendments are effective for us beginning on January 1, 2017. The amendments can be applied either through a full retrospective application or retrospectively with a cumulative effect adjustment on the date of initial adoption. Early adoption is prohibited. Management is assessing the impact of the adoption of this guidance.

Consolidation — Amendments to the Consolidation Analysis (ASU 2015-02)

In February 2015, the FASB issued ASU 2015-02. The amendments in this update modify the requirements of consolidation with respect to entities that are or are similar in nature to limited partnerships or are variable interest entities (VIEs). For entities that are or are similar to limited partnerships, the guidance clarifies the evaluation of kick-out rights, removes the presumption that the general partner will consolidate and generally states that such entities will be presumed to be VIEs unless proven otherwise. For VIEs, the guidance modifies the analysis related to the evaluation of servicing fees, excludes servicing fees that are deemed commensurate with the level of service required from the determination of the primary beneficiary and clarifies certain considerations related to the consolidation analysis when performing a related party assessment. The amendments are effective for us on January 1, 2016, with early adoption permitted. The amendments can be applied either through a full retrospective application or on a modified retrospective basis with a cumulative effect adjustment on the date of initial adoption. Management is assessing the impact of the adoption of this guidance.

Imputation of Interest — Simplifying the Presentation of Debt Issuance Costs (ASU 2015-03)

In April 2015, the FASB issued ASU 2015-03. The amendments in this update require that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. Currently debt issuance costs are presented as a deferred charge and are therefore presented as an asset. The recognition and measurement requirements will not change as a result of this guidance. The amendments are effective for us on January 1, 2016, with early adoption permitted. The amendments must be applied with retrospective application, with each balance sheet period presented showing the impacts of applying the guidance. The guidance is not expected to have a material impact to our consolidated financial condition or results of operations.

Loans held-for-sale represent loans that we intend to sell. In situations where we have not identified the specific loans to be sold, we may classify a percentage of the entire loan balance as held-for-investment and a percentage as held-for-sale based on an allocation methodology of loans with similar characteristics. In addition, we may also designate a portion of our originations as held-for-sale based on a similar allocation methodology.

Certain available-for-sale securities were sold at a loss in 2015 and 2014 as a result of market conditions within these respective periods (e.g., a downgrade in the rating of a debt security), in accordance with our risk management policies and practices. The table below summarizes available-for-sale securities in an unrealized loss position in accumulated other comprehensive income. Based on the methodology that was applied to these securities, we believe that the unrealized losses relate to factors other than credit losses in the current market environment. As of March 31, 2015, we did not have the intent to sell the debt securities with an unrealized loss position in accumulated other comprehensive income, and it is not more likely than not that we will be required to sell these securities before recovery of their amortized cost basis. As of March 31, 2015, we had the ability and intent to hold equity securities with an unrealized loss position in accumulated other comprehensive income, and it is not more likely than not that we will be required to sell these securities before recovery of their amortized cost basis. As a result, we believe that the securities with an unrealized loss position in accumulated other comprehensive income are not considered to be other-than-temporarily impaired at March 31, 2015. Refer to Note 1 to the Consolidated Financial Statements in our 2014 Annual Report on Form 10-K for additional information related to investment securities and our methodology for evaluating potential other-than-temporary impairments.

(a) Refer to Note 14 for further details on assets restricted as collateral for payment of the related debt.

We periodically enter into term repurchase agreements, short-term borrowing agreements in which we sell financial instruments to one or more investors while simultaneously committing to repurchase them at a specified future date, at the stated price plus accrued interest. As of March 31, 2015, the financial instruments sold under agreement to repurchase consisted of U.S. Treasury and Federal Agency securities with maturities as follows: $1.7 billion within the next 30 days and $504 million within 31 to 60 days. The primary risk associated with these repurchase agreements is that the counterparty will be unable to perform under the terms of the contract. As the borrower, we are exposed to the excess market value of the securities pledged over the amount borrowed. Daily mark-to-market collateral management is designed to limit this risk to the initial margin. However, should a counterparty declare bankruptcy or become insolvent, we may incur additional delays and costs.

Securitizations And Variable Interest Entities [Abstract]

Securitizations And Variable Interest Entities Disclosure [Text Block]

Securitizations and Variable Interest Entities

We are involved in several types of securitization and financing transactions that utilize special-purpose entities (SPEs). A SPE is an entity that is designed to fulfill a specified limited need of the sponsor. Our principal use of SPEs is to obtain liquidity by securitizing certain of our financial assets and operating lease assets.

The SPEs involved in our securitization and other financing transactions are generally considered VIEs. VIEs are entities that have either a total equity investment at risk that is insufficient to permit the entity to finance its activities without additional subordinated financial support or whose equity investors at risk lack the ability to control the entity's activities.

We provide a wide range of consumer and commercial automotive loans, operating leases, and commercial loans to a diverse customer base. We often securitize these loans (also referred to as financial assets) and leases through the use of securitization entities, which may or may not be consolidated on our Condensed Consolidated Balance Sheet.

There were no sales of financial assets into nonconsolidated securitization and asset-backed financing entities for the three months ended March 31, 2015 and 2014.

We have involvement with various other on-balance sheet, immaterial VIEs. Most of these VIEs are used for additional liquidity whereby we sell certain financial assets into the VIE and issue beneficial interests to third parties for cash. We also provide long-term guarantee contracts to investors in certain nonconsolidated affordable housing entities and have extended a line of credit to provide liquidity and minimize our exposure under these contracts. Since we do not have control over the entities or the power to make decisions, we do not consolidate the entities and our involvement is limited to the guarantee and the line of credit.

We have involvement with various other nonconsolidated affordable housing entities and venture capital funds. We do not consolidate these entities and our involvement is limited to the capital contributed and committed to these funds plus any previously recognized low income housing tax credits.

Refer to Note 10 to the Consolidated Financial Statements in our 2014 Annual Report on Form 10-K for further description of our securitization activities and our involvement with VIEs.

Our involvement with consolidated and nonconsolidated VIEs in which we hold variable interests is presented below.

(a) Asset values represent the current unpaid principal balance of outstanding consumer finance receivables and loans within the VIEs.

(b) Includes $10.2 billion and $12.7 billion of assets that are not encumbered by VIE beneficial interests held by third parties at March 31, 2015 and December 31, 2014, respectively. Ally or consolidated affiliates hold the interests in these assets which eliminate in consolidation.

(c) Maximum exposure to loss represents the current unpaid principal balance of outstanding loans based on our customary representation and warranty provisions. This measure is based on the unlikely event that all of the loans have underwriting defects or other defects that trigger a representation and warranty provision and the collateral supporting the loans are worthless. This required disclosure is not an indication of our expected loss.

(d) Includes $198 million and $164 million classified as other assets, offset by $16 million and $18 million classified as accrued expenses and other liabilities at March 31, 2015, and December 31, 2014, respectively.

(e) Includes a VIE for which we have no management oversight and therefore we are not able to provide the total assets of the VIEs.

Cash Flows with Off-balance Sheet Variable Interest Entities

The following table summarizes cash flows received and paid related to securitization entities and asset-backed financings where the transfer is accounted for as a sale and we have a continuing involvement with the transferred assets (e.g., servicing) that were outstanding during the three months endedMarch 31, 2015 and 2014. Additionally, this table contains information regarding cash flows received from and paid to nonconsolidated securitization entities that existed during each period.

Troubled Debt Restructurings

Troubled Debt Restructurings (TDRs) are loan modifications where concessions were granted to borrowers experiencing financial difficulties. Numerous initiatives are in place to provide support to our mortgage customers in financial distress, including principal forgiveness, maturity extensions, delinquent interest capitalization, and changes to contractual interest rates. Additionally for automotive loans, we may offer several types of assistance to aid our customers, including extension of the loan maturity date and rewriting the loan terms. Total TDRs recorded at historical cost and reported at carrying value before allowance for loan losses were $557 million and $681 million at March 31, 2015, and December 31, 2014, respectively. The decrease was primarily due to the whole-loan sale of consumer mortgage TDRs. Refer to Note 1 to the Consolidated Financial Statements in our 2014 Annual Report on Form 10-K for additional information.

The following table presents information related to finance receivables and loans recorded at historical cost modified in connection with a TDR during the period.

Servicing Activities

Automotive Finance Servicing Activities

We service consumer automotive contracts. Historically, we have sold a portion of our consumer automotive contracts. With respect to contracts we sell, we retain the right to service and earn a servicing fee for our servicing function. Typically, we conclude that the fee we are paid for servicing consumer automotive finance receivables represents adequate compensation, and consequently, we do not recognize a servicing asset or liability. We recognized automotive servicing fee income of $10 million and $9 million during the three months endedMarch 31, 2015 and 2014, respectively.

Description Of Business, Basis of Presentation, And Changes in Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2015

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Income Tax, Policy [Policy Text Block]

Income Taxes

In calculating the provision for interim income taxes, in accordance with Accounting Standards Codification (ASC) 740, Income Taxes, we apply an estimated annual effective tax rate to year-to-date ordinary income. At the end of each interim period, we estimate the effective tax rate expected to be applicable for the full fiscal year. This method differs from that described in Note 1 to the Consolidated Financial Statements in our 2014 Annual Report on Form 10-K, which describes our annual significant income tax accounting policy and related methodology.

Discontinued Operations, Policy [Policy Text Block]

Discontinued Operations

Prior to the adoption of ASU 2014-08, which is to be prospectively applied only to newly identified disposals that qualify as discontinued operations beginning after January 1, 2015, we have classified operations as discontinued when operations and cash flows will be eliminated from our ongoing operations and we do not expect to retain any significant continuing involvement in their operations after the respective sale or disposal transactions. For all periods presented, the operating results for these discontinued operations have been removed from continuing operations and presented separately as discontinued operations, net of tax, in the Condensed Consolidated Statement of Comprehensive Income. The Notes to the Condensed Consolidated Financial Statements have been adjusted to exclude discontinued operations unless otherwise noted.

Derivative Instruments And Hedging Activities

3 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities Disclosure [Text Block]

Derivative Instruments and Hedging Activities

We enter into interest rate, foreign-currency, and equity swaps, futures, forwards, options, and swaptions in connection with our market risk management activities. Derivative instruments are used to manage interest rate risk relating to specific groups of assets and liabilities, including automotive loan assets and debt. We use foreign exchange contracts to mitigate foreign-currency risk associated with foreign-currency-denominated debt, foreign exchange transactions, and our net investment in foreign subsidiaries. In addition, we also enter into equity option contracts to manage our exposure to the equity markets. Our primary objective for utilizing derivative financial instruments is to manage interest rate risk associated with our fixed and variable rate assets and liabilities, foreign exchange risks related to our foreign-currency denominated assets and liabilities, and market risks related to our investment portfolio and certain of our executive share-based compensation plans.

Interest Rate Risk

We monitor our mix of fixed- and variable-rate assets and liabilities. When it is cost-effective to do so, we may enter into interest rate swaps, forwards, futures, options, and swaptions to achieve our desired mix of fixed- and variable-rate assets and liabilities. We execute interest rate swaps, forwards, futures, options, and swaptions to modify our exposure to interest rate risk by converting certain fixed-rate instruments to a variable-rate and certain variable-rate instruments to a fixed-rate. We use a mix of both derivatives that qualify for hedge accounting treatment and economic hedges.

Derivatives qualifying for hedge accounting consist of receive-fixed swaps designated as fair value hedges of specific fixed-rate debt obligations, pay-fixed swaps designated as fair value hedges of specific portfolios of fixed-rate held-for-investment retail automotive loan assets, and pay-fixed swaps designated as cash flow hedges of the expected future cash flows in the form of interest payments on certain outstanding variable-rate borrowings associated with our secured debt.

We also execute economic hedges, which consist of interest rate swaps and interest rate caps held to mitigate interest rate risk associated with our debt portfolio. We also use interest rate swaps to economically hedge our net fixed-versus-variable interest rate exposure. We enter into economic hedges in the form of short-dated, exchange-traded Eurodollar futures to hedge the interest rate exposure of our fixed-rate automotive loans, as well as forwards, options, and swaptions to economically hedge our net fixed-versus-variable interest rate exposure.

Foreign Exchange Risk

We enter into derivative financial instrument contracts to mitigate the risk associated with variability in cash flows related to our various foreign-currency exposures.

We enter into foreign-currency forwards with external counterparties as net investment hedges of foreign exchange exposure on our investments in foreign subsidiaries. However, we have reduced our foreign exchange exposure to net investments in foreign operations through the sales and disposals of discontinued international businesses. Refer to Note 2 for further details on these sales.

Our remaining foreign subsidiaries in wind-down maintain both assets and liabilities in local currencies. These local currencies are generally the subsidiaries' functional currencies for accounting purposes. Foreign-currency-exchange-rate gains and losses arise when the assets or liabilities of our subsidiaries are denominated in currencies that differ from its functional currency. In addition, our equity is impacted by the cumulative translation adjustments resulting from the translation of foreign subsidiary results; this impact is reflected in our accumulated other comprehensive income (loss).

We utilize a cross-currency swap to economically hedge foreign exchange exposure on foreign-currency-denominated debt by converting the funding currency to our functional currency. This swap was entered into concurrent with the debt issuance with the terms of the derivative matching the terms of the underlying debt.

We also enter into foreign currency forwards to economically hedge our foreign denominated debt, our centralized lending program, and foreign-denominated third party loans. The hedge of foreign denominated debt was entered into concurrent with the debt issuance with the terms of the derivative matching the terms of the underlying debt. The centralized lending program manages liquidity for our subsidiary businesses, but as of March 31, 2015, this activity is immaterial. Foreign-currency-denominated loan agreements are executed with our foreign subsidiaries in their local currencies. We evaluate our foreign-currency exposure resulting from intercompany lending and manage our currency risk exposure by entering into foreign-currency derivatives with external counterparties. Our remaining foreign-currency derivatives, such as hedges of foreign-denominated third party loans, are recorded at fair value with changes recorded as income offsetting the gains and losses on the associated foreign-currency transactions.

Market Risk

We enter into equity options to economically hedge our exposure to the equity markets. We purchase options to assume a long position on certain equities and write options to assume a short position.

We have also entered into prepaid equity forward contracts to economically hedge the price risk associated with certain of our executive share-based compensation plans. The prepaid equity forward contracts are hybrid instruments containing an embedded forward contract, which is considered a derivative instrument. The embedded derivative instrument is bifurcated from the host contract and is recorded at fair value with changes in fair value recorded in compensation and benefits expense. The balance of the prepaid component of these equity forward contracts was $62 million as of March 31, 2015, and was recorded within other assets on the Condensed Consolidated Balance Sheet.

Counterparty Credit Risk

Derivative financial instruments contain an element of credit risk if counterparties are unable to meet the terms of the agreements. Credit risk associated with derivative financial instruments is measured as the net replacement cost should the counterparties that owe us under the contract completely fail to perform under the terms of those contracts, assuming no recoveries of underlying collateral as measured by the market value of the derivative financial instrument.

To mitigate the risk of counterparty default, we maintain collateral agreements with certain counterparties. The agreements require both parties to maintain collateral in the event the fair values of the derivative financial instruments meet established thresholds. In the event that either party defaults on the obligation, the secured party may seize the collateral. Generally, our collateral arrangements are bilateral such that we and the counterparty post collateral for the value of our total obligation to each other. Contractual terms provide for standard and customary exchange of collateral based on changes in the market value of the outstanding derivatives. The securing party posts additional collateral when their obligation rises or removes collateral when it falls.

Certain derivative instruments contain provisions that require us to either post additional collateral or immediately settle any outstanding liability balances upon the occurrence of a specified credit risk-related event. If a credit risk-related event had been triggered, the amount of additional collateral required to be posted by us would have been insignificant.

We placed cash and securities collateral totaling $228 million and $236 million at March 31, 2015 and December 31, 2014, respectively, in accounts maintained by counterparties, $18 million of which relates to non-derivative collateral at March 31, 2015 and December 31, 2014. We received cash collateral from counterparties totaling $118 million at March 31, 2015, $13 million of which relates to non-derivative collateral. We received cash collateral from counterparties totaling $71 million at December 31, 2014. The receivables for collateral placed and the payables for collateral received are included on our Condensed Consolidated Balance Sheet in other assets and accrued expenses and other liabilities, respectively. In certain circumstances, we receive or post securities as collateral with counterparties. We do not record such collateral received on our Condensed Consolidated Balance Sheet unless certain conditions are met. At March 31, 2015 and December 31, 2014, we received noncash collateral of $24 million and $15 million, respectively.

Balance Sheet Presentation

The following table summarizes the fair value amounts of derivative instruments reported on our Condensed Consolidated Balance Sheet. The fair value amounts are presented on a gross basis, are segregated by derivatives that are designated and qualifying as hedging instruments or those that are not, and are further segregated by type of contract within those two categories. Notional amounts are reference amounts from which contractual obligations are derived and are not recorded on the balance sheet. In our view, derivative notional is not an accurate measure of our derivative exposure when viewed in isolation from other factors, such as market rate fluctuations and counterparty credit risk.

Income Tax Disclosure [Abstract]

Income Tax Disclosure [Text Block]

Income Taxes

We recognized total income tax expense from continuing operations of $103 million during the three months endedMarch 31, 2015, compared to income tax expense of $94 million for the same period in 2014. The increase in income tax expense for the three months endedMarch 31, 2015, compared to the same period in 2014, was driven primarily by a reduction in tax credits.

As of each reporting date, we consider existing evidence, both positive and negative, that could impact our view with regard to future realization of deferred tax assets. We continue to believe it is more likely than not that the benefit for certain foreign tax credits and state net operating loss carryforwards will not be realized. In recognition of this risk, we continue to provide a partial valuation allowance on the deferred tax assets relating to these carryforwards.

It is reasonably possible the unrecognized tax benefits disclosed in our 2014 Annual Report on Form 10-K will decrease by up to $180 million over the next 12 months if certain tax matters ultimately settle with the applicable taxing jurisdiction as anticipated.
