Report of Independent Registered Public Accounting Firm

To the Administrator of the

Capital One Financial Corporation Associate Savings Plan

We have audited the accompanying statements of net assets available for benefits of the Capital One Financial Corporation Associate Savings Plan (the “Plan”) as of December 31, 2012 and 2011, and the related statements of changes in net assets available for benefits for the years then ended. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Capital One Financial Corporation Associate Savings Plan as of December 31, 2012 and 2011, and the changes in its net assets available for benefits for the years then ended in conformity with accounting principles generally accepted in the United States.

Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules of Schedule H, Line 4a – Schedule of Delinquent Participant Contributions and Schedule H, Line 4i – Schedule of Assets (Held at End of Year) are presented for the purpose of additional analysis and are not a required part of the basic financial statements, but are supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. These supplemental schedules are the responsibility of the Plan’s management. These supplemental schedules have been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated in all material aspects in relation to the basic financial statements taken as a whole.

Capital One Financial Corporation Associate Savings Plan

Notes to Financial Statements

Note 1—Description of Plan

Effective January 1, 1995, Capital One Financial Corporation (the “Company”) established and adopted the Capital One Financial Corporation Associate Savings Plan (the “Plan”) for the benefit of its eligible employees. Effective December 31, 2012, the ING Direct 401(k) Savings Plan and ING Direct Pension Plan (the “INGD Plans”), both of which are defined contribution plans, were merged into the Plan. The INGD Plans’ net assets of $136,387,399 as of December 31, 2012, were received by the Plan in January 2013, in accordance with Section 414(I) of the Internal Revenue Code of 1986, as amended. The Company makes contributions to each eligible associate’s account and matches a portion of associate contributions.

The Benefits Committee of the Company was the Plan administrator, and Fidelity Management Trust Company (the “Trustee”) was the Plan trustee for both the 2012 and 2011 Plan years.

The following description of the Plan provides only general information. Participants should refer to the Plan document for a more complete description of the Plan’s provisions.

General

The Plan is a defined contribution plan covering all employees of the Company and certain affiliates who are age 18 or older. Eligible employees are automatically enrolled in the Plan immediately upon hire unless they elect to opt-out of Plan participation. The Plan is a qualified defined contribution retirement plan under Internal Revenue Code Section 401(k) and subject to the provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”), as amended.

Contributions

Under the Plan, participants can elect to make annual pre-tax and Roth contributions of no more than 50% of their eligible compensation, subject to Internal Revenue Service (“IRS”) limitations. The IRS limitation was $17,000 for 2012 and $16,500 for 2011. Participants who are age 50 or older at the end of a particular calendar year are permitted to make additional elective deferral contributions of $5,500. Participants may also contribute amounts representing distributions from other qualified plans as roll-over contributions. The Company’s contributions, which provide for a maximum annual Company contribution of up to 7.5% of eligible compensation, consist of two major components: (1) a basic safe-harbor non-elective contribution, and (2) two Company matching contributions. The Plan’s contribution structure is summarized in the following table.

Contribution Type	Contribution Structure
1.      Basic safe-harbor non-elective contribution	•   3% of eligible compensation
2.      Company matching contributions	•   Up to 3% of eligible compensation, calculated as 100% Company match on the first 3% of associate deferrals •   Up to 1.5% of eligible compensation, calculated as 50% Company match on the next 3% of associate deferrals
Total annual contribution opportunity	•   Maximum of 7.5% of eligible compensation

The basic safe-harbor non-elective contribution of 3% of eligible compensation, as defined in the Plan document, is made for all eligible employees regardless of participation in the Plan. In addition, the Company makes matching contributions of up to 4.5% of a participant’s eligible compensation. The Company makes “true-up” matching contributions for participants who did not receive the full match to which participants would have been entitled if participants had contributed to the Plan ratably throughout the year. Employees who have made pre-tax and/or Roth contributions to the Plan during the Plan year are eligible for the Company matching contributions. The Company makes contributions on a per-pay period basis, and new employees become immediately eligible for the Company’s matching contributions. All Company contributions are cash contributions.

Notes to Financial Statements (Continued)

Participant Accounts

Each participant’s account is credited with the participant’s contributions and allocations of the Company’s contributions and Plan earnings. Allocations of employer contributions are determined based on participant contributions or eligible compensation, as defined in the Plan document. Allocations of Plan earnings are determined based upon the number of units of the Plan’s investment options in each participant’s account. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account as of the date of record.

Vesting

Participant contributions and the earnings on those contributions vest immediately. The Company’s basic contributions also vest immediately. The Company’s matching contributions plus actual earnings thereon vest after two years of service.

Forfeited Accounts

Excess forfeited balances of terminated participants’ non-vested accounts, after payment of administrative expenses, are used to reduce future Company contributions. Forfeited non-vested accounts totaled $2,006,773 and $789,069 as of December 31, 2012 and 2011, respectively. Forfeitures used to reduce administrative expense totaled $777,094 and $626,140 in 2012 and 2011, respectively.

Investment Options

All investments in the Plan are participant-directed. Participants may change their investment options at any time. As of December 31, 2012, the Company offered 24 investment options, which are summarized below:

• BGI LifePath Fund (2015, 2020, 2025, 2030, 2035, 2040, 2045, 2050, 2055 and Retirement)—Each fund is a broadly diversified portfolio, tailored to the investment horizon of the fund. The name of each fund (e.g., BGI LifePath 2015) represents the year during which the investor will most likely begin to draw income and/or principal out of his or her investment portfolio.

• Capital One Pooled Company Stock Fund—Monies are invested by the Trustee in a unitized trust fund which invests in shares of the Company’s common stock. The Trustee is also permitted to invest in short-term temporary investments, including pooled funds which bear interest at market rates.

• Dodge & Cox Balanced Fund—Monies are primarily invested in a diversified mix of common and preferred stocks and investment-grade bonds, generally rated in the top four rating categories.

• Dodge & Cox International Stock Fund—Monies are primarily invested in equity securities of companies outside the U.S. from at least three different foreign countries, including emerging markets.

• Fidelity BrokerageLink—This self-directed option allows participants to invest in mutual funds and other investment options beyond the investment options offered directly through the Plan.

• Fidelity Capital Appreciation Fund—Monies are primarily invested in common stocks.

• Goldman Sachs Large Cap Value Fund—Monies are primarily invested in a diversified portfolio of equity investments in large-cap U.S. issuers with public stock market capitalizations within the range of the market capitalization of companies constituting the Russell 1000^® Value Index at the time of investment.

• Hartford Mid Cap Fund—Monies are primarily invested in common stocks of mid-capitalization companies.

5

Capital One Financial Corporation Associate Savings Plan

Notes to Financial Statements (Continued)

• Hartford Small Company Fund—Monies are primarily invested in common stocks of small capitalization companies.

• Invesco Stable Value Fund—Monies are invested in a diversified portfolio of investment contracts issued by high-quality insurance companies and banks, with each contract carrying a crediting rate of interest, and backed by high quality securities.

• Lazard Emerging Markets Equity Fund—Monies are primarily invested in equity securities of companies whose principal business activities are located in emerging market countries, with a focus on Latin America, the Pacific Basin and Eastern Europe.

• Northern Small Cap Value Fund—Monies are primarily invested in equity securities of small capitalization companies.

• PIMCO Total Return Fund—Monies are invested in all types of bonds, including U.S. government, corporate, mortgage and foreign.

• Spartan U.S. Equity Index Fund—Monies are primarily invested in common stocks included in the S&P 500 Index, which broadly represents the performance of common stocks publicly traded in the United States.

• Wells Fargo Capital Growth Fund—Monies are primarily invested in securities of large-capitalization companies that the manager believes to offer the potential for above-average earnings growth.

Participant Notes Receivable

Participants may elect to borrow from their fund accounts a minimum of $1,000 and up to a maximum of the lesser of $50,000, or 50% of their vested account balance. Loan transactions are treated as a transfer from (to) the investment fund to (from) the loan fund. Loan terms range from one to five years or up to 10 years for the purchase of a primary residence. The loans are secured by the balance in the participant’s account and bear interest at a rate commensurate with local prevailing rates as determined by the Benefits Committee. Principal and interest are paid ratably through bi-weekly payroll deductions. Management has evaluated participant notes receivable for collectability and has determined that no allowance is considered necessary.

Payment of Benefits

A participant may elect to receive an amount up to the vested value of his or her account through a lump-sum distribution upon the participant’s death, hardship, retirement, termination of service or for other reasons as governed by the Plan document. If the participant has invested in the Capital One Pooled Company Stock Fund, he or she may elect to receive distributions of whole shares of common stock with fractional shares paid in cash.

Administrative Expenses

Accounting fees are paid by the Company. The majority of administrative expenses of the Plan are paid by the Company, with the remainder offset by forfeitures.

Note 2—Summary of Significant Accounting Policies

Basis of Accounting

The financial statements of the Plan are prepared in accordance with generally accepted accounting principles in the U.S. (“GAAP”). Benefits are recorded when paid.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Valuation and Income Recognition

The Plan’s investments are reported at fair value and securities transactions are recorded as of the trade-date. The fair value of units in the Capital One Pooled Company Stock Fund is determined based upon the stock price of the last reported sales transaction on the last business day of the Plan year. The fair value of shares of registered investment companies is based on quoted market prices, which represent the net asset values of shares held by the Plan as of year end. The Plan’s investment in the Invesco Stable Value Fund has underlying investments in guaranteed investment contracts (“GICs”) and synthetic GICs, as well as cash equivalents, and is measured and accounted for based on contract value. The contract value is equal to the principal balance plus accrued interest, which represents the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan. These fully benefit-responsive investment contracts are reported at fair value in the Plan’s Statements of Net Assets Available for Benefits, with a corresponding adjustment to reflect these investments at contract value. The Statements of Changes in Net Assets Available for Benefits have been prepared on a contract value basis for the years ended December 31, 2012 and 2011.

Participant notes receivable are recorded at their unpaid principal balance plus any accrued but unpaid interest.

Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date.

Recently Issued and Adopted Accounting Guidance

Fair Value Measurement: Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (“IFRS”)

In May 2011, the Financial Accounting Standards Board (“FASB”) issued amended guidance on fair value that is intended to provide a converged fair value framework for U.S. GAAP and IFRS. The amended guidance results in a consistent definition of fair value and common requirements for measurement of and disclosure about fair value between U.S. GAAP and IFRS. While the amended guidance continues to define fair value as an exit price, it changes some fair value measurement principles and expands the existing disclosure requirements for fair value measurements. The amended guidance is effective for public entities for interim and annual periods beginning on or after December 15, 2011, with early adoption prohibited. The new guidance requires prospective application and disclosure in the period of adoption of the change, if any, in valuation techniques and related inputs resulting from application of the amendments and quantification of the total effect, if practicable. The Plan adopted this guidance on January 1, 2012. The Plan’s adoption of this guidance did not affect the Statements of Net Assets Available for Benefits or the Statements of Changes in Net Assets Available for Benefits. See “Note 4— Fair Value Measurements” for additional information and related disclosures regarding fair value measurements.

Notes to Financial Statements (Continued)

Risks and Uncertainties

The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the Statements of Net Assets Available for Benefits.

Note 3—Investments

The Plan’s investments are held in a trust administered by the Trustee. A complete listing of the Plan’s investments as of December 31, 2012 is included in the Schedule H, Line 4i – Schedule of Assets (Held at End of Year). The table below presents investments that represented 5% or more of the Plan’s net assets as of December 31, 2012 and 2011.

Fully Benefit-Responsive Investment Contracts

The Invesco Stable Value Fund (the “Fund”) invests primarily in investment contracts such as traditional GICs and wrapper contracts (also known as synthetic GICs). In a traditional GIC, the issuer takes a deposit from the Fund and purchases investments that are held in the issuer’s general account. The issuer is contractually obligated to repay the principal and a specified rate of interest guaranteed to the Fund. In a wrapper contract structure, the underlying investments are owned by the Fund and held in trust for Plan participants. The Fund purchases a wrapper contract from an insurance company or bank. The wrapper contract amortizes the realized and unrealized gains and losses on the underlying fixed income investments, typically over the duration of the investment, through adjustments to the future interest crediting rate (which is the rate earned by participants in the Fund for the underlying investments).

The issuer of the wrapper contract provides assurance that the adjustments to the interest crediting rate do not result in a future interest crediting rate that is less than zero. An interest crediting rate less than zero would result in a loss of principal or accrued interest. The key factors that influence future interest crediting rates for a wrapper contract include the level of market interest rates, the amount and timing of participant contributions, transfers and withdrawals into and out of the wrapper contract, the investment returns generated by the fixed income investments that back the wrapper contract and the duration of the underlying investments backing the wrapper contract. Wrapper contracts’ interest crediting rates are typically reset on a monthly or quarterly basis.

In certain circumstances, the amount withdrawn from the wrapper contract would be payable at fair value rather than at contract value. These circumstances include termination of the Plan; a material adverse change to the provisions of the Plan; the Company making an election to withdraw from a wrapper contract in order to switch to a different investment provider; or the terms of a successor Plan (in the event of spin-off or sale of a division) do not meet the wrapper contract issuer’s underwriting criteria for the issuance of a clone wrapper contract. Examples of events that would permit a wrapper contract issuer to terminate a wrapper contract upon short notice include the Plan’s loss of its qualified status; un-cured material breaches of responsibilities; or material and adverse changes to the provisions of the Plan. If one of these events occurred, the wrapper contract issuer could terminate the wrapper contract at the market value of the underlying investments (or in the case of a traditional GIC, at the hypothetical market value based upon a contractual formula). The Plan administrator believes that the events noted above that limit the Plan’s ability to execute transactions at contract value are unlikely to occur.

8

Capital One Financial Corporation Associate Savings Plan

Notes to Financial Statements (Continued)

The Fund is presented in the financial statements at contract value, as reported to the Plan by the Trustee. There are no reserves against contract value for credit risk of the contract issuer or otherwise as of December 31, 2012 or 2011. The average yield for the investment contracts based on actual earnings was 0.91% and 1.47% for 2012 and 2011, respectively. This average yield represents the annualized earnings of all investments in the Fund during each year divided by the fair value of all investments in the Fund. The average yield adjusted to reflect the actual interest rate credited to participants was 2.13% and 3.14% for 2012 and 2011, respectively. The average credited yield represents the annualized earnings credited to participants in the Fund during each year divided by the fair value of all investments in the Fund.

Note 4—Fair Value Measurement

Fair value is defined as the price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date (also referred to as an exit price). The fair value accounting guidance provides a three-level fair value hierarchy for classifying financial instruments. This hierarchy is based on whether the inputs to the valuation techniques used to measure fair value are observable or unobservable. Fair value measurement of a financial asset or liability is assigned to a level based on the lowest level of any input that is significant to the fair value measurement in its entirety. The three levels of the fair value hierarchy are described below:

• Level 1—Quoted prices (unadjusted) in active markets for identical assets or liabilities.

• Level 2—Observable market-based inputs, other than quoted prices in active markets for identical assets or liabilities.

• Level 3—Unobservable inputs.

Level 1, 2 and 3 Valuation Techniques

The valuation of financial instruments is classified as Level 1 when it is determined based on quoted prices in active markets for identical assets or liabilities. The valuation is classified as Level 2 when it is determined based on quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or models using inputs that are observable or can be corroborated by observable market data of substantially the full term of the assets or liabilities. The valuation is classified as Level 3 when it is determined based on the use of pricing models, discounted cash flow methodologies or similar techniques, and at least one significant model assumption or input is unobservable and the determination of the fair value requires significant management judgment or estimation. The accounting guidance for fair value requires that the use of observable inputs be maximized and the use of unobservable inputs be minimized in determining fair value.

The determination of the classification of financial instruments in Level 2 or Level 3 of the fair value hierarchy is performed at the end of each reporting period, taking into consideration all available information, including observable market data, indications of market liquidity and orderliness, and the valuation techniques and significant inputs. Based upon the specific facts and circumstances of each instrument or instrument category, judgments are made regarding the significance of the Level 3 inputs to the instrument’s fair value measurement in its entirety. If Level 3 inputs are considered significant, the instrument is classified as Level 3.

Total unrealized losses		(194,999	)
Balance as of December 31, 2012	$	—

Level 3 Valuation Techniques

The fair value of wrapper contracts is determined based on the present value of excess future wrap fees. When the replacement cost of the wrapper contract (a re-pricing provided annually by the contract issuer) is greater than the current wrap fee, the difference is converted into the implied additional fee payment cash flows for the duration of the holding. The present value of that cash flow stream is calculated using a swap curve yield that is based on the duration of the holding and adjusted for the holding’s credit quality rating. Because the replacement cost of the wrapper contracts held by the Plan at December 31, 2012 did not exceed the current wrap fee, the fair value of these assets was zero as of December 31, 2012. Certain other disclosures related to the fair value of the wrapper contracts have not been presented since the fair value of the contracts is not material to the Plan’s investment in the Invesco Stable Value Fund.

Note 5—Plan Termination

Although it has not expressed any intent to do so, the Company has the right to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants will become 100% vested in their accounts.

Note 6—Income Tax Status

The Plan received a determination letter from the Internal Revenue Service dated January 12, 2004, stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (the “Code”); therefore, the related trust is exempt from taxation. Subsequent to the issuance of this determination letter, the Plan was amended. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. Because the Plan is being operated in compliance with the applicable requirements of the Code, the Plan administrator believes that the Plan is qualified and the related trust is tax exempt.

Note 7—Transactions with Parties-in-Interest

Transactions involving the investments presented below, which reflect the fair value as of December 31, 2012 and 2011, are considered to be party-in-interest transactions for which a statutory exception exists.

Note 9—Prohibited Transactions

During the Plan year ended December 31, 2012, the Company failed to remit certain contributions to the Plan timely, as reflected in Schedule H, Line 4a – Schedule of Delinquent Participant Contributions. The Company remitted the contributions to the Plan in December 2012 and submitted additional funds for lost earnings to the affected participants’ accounts in January 2013. The Company reported these transactions to the Department of Labor under its Voluntary Fiduciary Correction Program (“VFCP”), and received confirmation of approval of the Company’s corrective action in a letter dated May 2, 2013.

Notes to Financial Statements (Continued)

Note 10—Subsequent Events

In accordance with U.S. GAAP, the Plan evaluates subsequent events that have occurred after the balance sheet date but before the financial statements are issued. There are two types of subsequent events: (1) recognized, or those that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements, and (2) non-recognized, or those that provide evidence about conditions that did not exist at the date of the balance sheet but arose after that date. The Plan evaluated subsequent events through June 25, 2013, the financial statement issuance date.

Based on the evaluation, the Plan did not identify any recognized or non-recognized subsequent events that would have required adjustment to the financial statements.
