(h) The Federal Reserve’s Notices of Proposed Rulemaking (“NPRs”) require the Tier 1 common equity ratio to be the lower of the ratio as calculated under the Standardized Approach or Advanced Approach. At March 31, 2013, this ratio was 9.4% under the Standardized Approach compared with 9.7% under the Advanced Approach. At Dec. 31, 2012, this ratio was higher under the Standardized Approach, and therefore was presented under the Advanced Approach. The estimated Basel III Tier 1 common equity ratio of 7.6% at March 31, 2012 was based on prior Basel III guidance and the proposed market risk rule.

(i) In the first quarter of 2013, BNY Mellon was required to implement the Basel II.5 – final market risk rule. Implementation of these rules resulted in an approximately 35-40 basis points decrease to the Basel I Tier I common equity to risk-weighted assets ratio, the Basel I Tier I capital ratio and the Basel I Total capital ratio. Prior period ratios were not impacted by the implementation.

Items 2. and 3. Management’s Discussion and Analysis of Financial Condition and Results of Operations; Quantitative and Qualitative Disclosures about Market Risk

General

In this Quarterly Report on Form 10-Q, references to “our,” “we,” “us,” “BNY Mellon,” the “Company” and similar terms refer to The Bank of New York Mellon Corporation and its consolidated subsidiaries. The term “Parent” refers to The Bank of New York Mellon Corporation but not its subsidiaries.

Certain business terms used in this report are defined in the Glossary included in our Annual Report on Form 10-K for the year ended Dec. 31, 2012 (“2012 Annual Report”).

The following should be read in conjunction with the Consolidated Financial Statements included in this report. Investors should also read the section titled “Forward-looking Statements.”

How we reported results

Throughout this Form 10-Q, measures, which are noted as “Non-GAAP financial measures,” exclude certain items. BNY Mellon believes that these measures are useful to investors because they permit a focus on period-to-period comparisons using measures that relate to our ability to enhance revenues and limit expenses in circumstances where such matters are within our control. We also present the net interest margin on a fully taxable equivalent (“FTE”) basis. We believe that this presentation allows for comparison of amounts arising from both taxable and tax-exempt sources and is consistent with industry practice. Certain immaterial reclassifications have been made to prior periods to place them on a basis comparable with the current period presentation. See “Supplemental information - Explanation of Non-GAAP financial measures” beginning on page 48 for a reconciliation of financial measures presented in accordance with U.S. generally accepted accounting principles (“GAAP”) to adjusted Non-GAAP financial measures.

Overview

BNY Mellon is the corporate brand of The Bank of New York Mellon Corporation (NYSE symbol: BK). BNY Mellon is a global investments company dedicated to helping its clients manage and service their financial assets throughout the investment lifecycle. Whether providing financial services for institutions, corporations or individual investors, BNY Mellon delivers informed investment management and investment services in 36 countries and more than 100 markets. As of March 31, 2013, BNY Mellon had $26.3 trillion in assets under custody and/or administration, and $1.4 trillion in assets under management. BNY Mellon can act as a single point of contact for clients looking to create trade, hold, manage, service, distribute or restructure investments.

Key first quarter 2013 and subsequent events

ConvergEx

In early April 2013, ConvergEx, an entity in which BNY Mellon has a minority interest, completed a divestiture of its software platform business.  As a result of the divestiture and other events, we anticipate recognizing an after-tax gain of approximately $100 million on our investment in ConvergEx in the second quarter of 2013.

Sale of SourceNet Solutions

At the end of the first quarter of 2013, BNY Mellon entered into an agreement to sell our SourceNet Solutions business.  SourceNet Solutions is BNY Mellon’s accounts payable outsourcing support services provider that operates as part of our Investment Services business.  The closing is expected to take place during the second quarter of 2013.  We anticipate recording an immaterial gain as a result of this sale.

BNY Mellon 4

Capital plan and share repurchase program and dividend increase

In March 2013, BNY Mellon received confirmation that the Board of Governors of the Federal Reserve System (the “Federal Reserve”) did not object to our 2013 capital plan submitted in connection with the Federal Reserve’s Comprehensive Capital Analysis and Review (“CCAR”). The board of directors subsequently approved the repurchase of up to $1.35 billion worth of common shares, a 16% increase from the prior year’s board authorization, and a 15% increase in BNY Mellon’s quarterly common stock dividend.

From April 1, 2013 through May 8, 2013, we repurchased 11.0 million common shares in the open market, at an average price of $27.64 per common share for a total of $304 million.

On April 9, 2013, The Bank of New York Mellon Corporation announced a 15% increase in the quarterly common stock dividend, from $0.13 per share to $0.15 per share. This cash dividend was paid to shareholders on May 7, 2013.

Agreement to sell Newton’s Private Client Business

On Feb. 27, 2013, Newton Management Limited, together with Newton Investment Management Limited, an investment boutique of BNY Mellon, announced an agreement to sell Newton’s private client business. The agreement covers 7% of Newton’s assets under management valued at £3.6 billion and approximately 3,000 private clients. The transaction is anticipated to close in the third quarter of 2013, subject to regulatory approval. We expect this transaction to be immaterial to our results of operations.

U.S. Tax Court Ruling

As previously disclosed, on Feb. 11, 2013, the U.S. Tax Court issued a ruling against BNY Mellon upholding the IRS’ disallowance of certain foreign tax credits claimed for the 2001 and 2002 tax years. As a result of the ruling, BNY Mellon recorded an $854 million after-tax charge, or $0.73 per common share, in the first quarter of 2013.

BNY Mellon will appeal the court’s decision. We continue to believe the tax treatment of the

transaction was consistent with statutory and judicial authority existing at the time.

Highlights of first quarter 2013 results

In the first quarter of 2013, we reported a net loss applicable to common shareholders of BNY Mellon of $266 million, or $0.23 per diluted common share, which included a previously announced charge of $854 million, or $0.73 per common share, related to the U.S. Tax Court’s disallowance of certain foreign tax credits. Excluding this charge, net income applicable to common shareholders was $588 million and earnings per diluted common share was $0.50. This compares with net income of $619 million, or $0.52 per diluted common share, in the first quarter of 2012.

Highlights of first quarter 2013 include:

• Assets under custody and/or administration (“AUC/A”) totaled $26.3 trillion at March 31, 2013 compared with $25.7 trillion at March 31, 2012 and $26.3 trillion at Dec. 31, 2012. The increase of 2% year-over-year primarily reflects net new business and improved market values. (See the “Investment Services business” beginning on page 19.)

• Assets under management (“AUM”) totaled a record $1.43 trillion at March 31, 2013 compared with $1.31 trillion at March 31, 2012 and $1.39 trillion at Dec. 31, 2012. This represents an increase of 9% year-over-year and 3% sequentially. Both increases primarily resulted from net new business and higher market values. (See the “Investment Management business” beginning on page 16).

• Investment services fees totaled $1.7 billion in the first quarter of 2013 compared with $1.6 billion in the first quarter of 2012. The increase was driven by improved asset servicing, treasury and clearing services revenue, partially offset by lower issuer services and securities lending revenue. (See the “Investment Services business” beginning on page 19).

• Investment management and performance fees totaled $822 million in the first quarter of 2013 compared with $745 million in the first quarter of 2012. The increase was driven by the acquisition of the remaining 50% interest in Meriten Investment Management (“Meriten”), higher market values, net new business and lower money market fee waivers. (See the

5 BNY Mellon

“Investment Management business” beginning on page 16).

• Foreign exchange and other trading revenue totaled $161 million in the first quarter of 2013 compared with $191 million in the first quarter of 2012. The decrease was driven by lower other trading revenue partially offset by higher foreign exchange revenue. (See “Fee and other revenue” beginning on page 7).

• Investment income and other revenue totaled $72 million in the first quarter of 2013 compared with $139 million in the first quarter of 2012. The decrease primarily resulted from lower leasing gains, foreign currency remeasurement and seed capital gains. (See “Fee and other revenue” beginning on page 7).

• Net interest revenue totaled $719 million in the first quarter of 2013 compared with $765 million in the first quarter of 2012. The net interest margin (FTE) was 1.11% in the first quarter of 2013 compared with 1.32% in the first quarter of 2012. Both decreases primarily reflect lower reinvestment yields, lower accretion and the elimination of interest on European Central Bank Deposits. (See “Net interest revenue” beginning on page 10).

• The provision for credit losses was a credit of $24 million in the first quarter of 2013 compared with a provision of $5 million in the first quarter of 2012. (See “Asset quality and allowance for credit losses” beginning on page 32).

• Noninterest expense was flat year-over-year totaling $2.8 billion in both the first quarter of 2013 and the first quarter of 2012. (See “Noninterest expense” beginning on page 12).

• BNY Mellon recorded an income tax provision of $1 billion in the first quarter of 2013, which included the $854 million charge related to the disallowance of certain foreign tax credits. (See “Income taxes” on page 13).

• The net unrealized pre-tax gain on our total investment securities portfolio was $2.2 billion at March 31, 2013 compared with $2.4 billion at Dec 31, 2012. The decrease primarily reflects an increase in market interest rates and $48 million of realized security gains in the first quarter of 2013. (See “Investment securities” beginning on page 27).

• At March 31, 2013, our estimated Basel III Tier 1 common equity ratio was 9.4% compared with 9.8% at Dec. 31, 2012. (See “Capital” beginning on page 41).

• Our Basel I Tier 1 capital ratio was 13.6% at March 31, 2013 and 15.0% at Dec. 31, 2012. (See “Capital” beginning on page 41).

• In the first quarter of 2013, we repurchased 7.8 million common shares in the open market, at an average price of $27.21 per share, for a total of $211 million.

(c) Reflects revisions, which were not material, for prior periods as a result of our previously disclosed reviews of our AUC/A and our process for reporting information. See pages 4-5 of our 2012 Annual Report. Includes the AUC/A of CIBC Mellon of $1.2 trillion at March 31, 2013, $1.1 trillion at Dec. 31, 2012 and $1.2 trillion at March 31, 2012.

Fee and other revenue

Fee and other revenue totaled $2.8 billion in the first quarter of 2013, essentially unchanged both year-over-year and sequentially. Year-over-year, higher investment management and performance fees and asset servicing revenue were offset by lower investment and other income and lower foreign exchange and other trading revenue. Sequentially, higher asset servicing, issuer services and foreign exchange and other trading revenue were offset by lower investment and other income.

Investment services fees

Investment services fees were impacted by the following compared with the first quarter of 2012 and the fourth quarter of 2012:

• Asset servicing fees increased 3% year-over-year and 3% (unannualized) sequentially, primarily driven by increased activity with existing clients and improved market values, partially offset by lower securities lending revenue.

• Issuer services fees decreased 6% year-over-year and increased 10% (unannualized) sequentially. The year-over-year decrease primarily resulted from lower Depositary Receipts revenue, driven by lower issuance volumes and lower servicing fees. The sequential increase primarily resulted from higher Depositary Receipts revenue driven by an improvement in dividends and higher core volumes, partially offset by lower Corporate Trust revenue reflecting the continued net run-off of structured debt securitizations. We continue to estimate this run-off could reduce the Company’s total annual revenue by approximately one-half to three-quarters of 1% if the structured debt markets do not recover.

• Clearing services fees increased slightly year-over-year and 3% (unannualized) sequentially. Both increases primarily resulted from higher mutual fund fees, increases in positions and assets, higher cash management fees and an increase in daily average revenue trades (“DARTS”), partially offset by higher money market fee waivers and fewer trading days.

• Treasury services fees increased 4% year-over-year and were unchanged sequentially. The

7 BNY Mellon

year-over-year increase primarily reflects higher cash management fees.

See the “Investment Services business” in “Review of businesses” for additional details.

Investment management and performance fees

Investment management and performance fees totaled $822 million in the first quarter of 2013, an increase of 10% year-over-year and a decrease of 4% (unannualized) sequentially. The year-over-year increase was impacted by the acquisition of the remaining 50% interest in Meriten. Excluding the Meriten acquisition, investment management and performance fees increased 9% year-over-year driven by higher market values, net new business and lower money market fee waivers. The sequential decrease reflects seasonally lower performance fees and higher money market fee waivers, partially offset by higher market values. Comparisons to both prior periods were negatively impacted by the stronger U.S. dollar. Performance fees were $15 million in the first quarter of 2013, $16 million in the first quarter of 2012 and $56 million in the fourth quarter of 2012.

Total AUM for the Investment Management business was a record $1.4 trillion at March 31, 2013, a 9% increase compared with the prior year and 3% (unannualized) sequentially. Both increases resulted from net new business and higher market values. In the first quarter of 2013, long-term inflows totaled a record $40 billion primarily benefiting from liability-driven investments as well as equity and fixed income funds.

See the “Investment Management business” in “Review of businesses” for additional details regarding the drivers of investment management and performance fees.

The year-over-year increase primarily reflects higher volumes, partially offset by a decrease in volatility, while the sequential increase reflects increased volatility and higher volumes. Additionally, foreign exchange revenue continues to be impacted by increasingly competitive market pressures. Other trading revenue totaled $12 million in the first quarter of 2013, compared with $55 millionfirst quarter of 2012 and $33 million in the fourth quarter of 2012. Both decreases were principally due to losses on interest rate hedges and lower fixed income and equity trading. Foreign exchange revenue and fixed income trading revenue is reported in the Investment Services business and the Other segment. Equity/other trading revenue is primarily reported in the Other segment.

The foreign exchange trading engaged in by the Company generates revenues, which are influenced by the volume of client transactions and the spread realized on these transactions. The level of volume and spreads is affected by market volatility, the level of cross-border assets held in custody for clients, the level and nature of underlying cross-border investments and other transactions undertaken by corporate and institutional clients. These revenues also depend on our ability to manage the risk associated with the currency transactions we execute. A substantial majority of our foreign exchange trades is undertaken for our custody clients in transactions where BNY Mellon acts as principal, and not as an agent or broker. As a principal, we earn a profit, if any, based on our ability to risk manage the aggregate foreign currency positions that we buy and sell on a daily basis. Generally speaking, custody clients enter into foreign exchange transactions in one of three ways: negotiated trading with BNY Mellon, BNY Mellon’s standing instruction program, or transactions with third-party foreign exchange providers. Negotiated trading generally refers to orders entered by the client or the client’s investment manager, with all decisions related to the transaction, usually on a transaction-specific basis, made by the client or its investment manager. Such transactions may be initiated by (i) contacting one of our sales desks to negotiate the

BNY Mellon 8

rate for specific transactions, (ii) using electronic trading platforms, or (iii) electing other methods such as those pursuant to a benchmarking arrangement, in which pricing is determined by an objective market rate plus a pre-negotiated spread. The preponderance of the notional value of our trading volume with clients is in negotiated trading. Our standing instruction program, including a standing instruction program option called the Defined Spread Offering, which the Company introduced to clients in the first quarter of 2012, provides custody clients and their investment managers with an end-to-end solution that allows them to shift to BNY Mellon the cost, management and execution risk, often in small transactions not otherwise eligible for a more favorable rate or transactions in restricted and difficult to trade currencies. We incur substantial costs in supporting the global operational infrastructure required to administer the standing instruction program; on a per-transaction basis, the costs associated with the standing instruction program exceed the costs associated with negotiated trading. In response to competitive market pressures and client requests, we are continuing to develop standing instruction program products and services and making these new products and services available to our clients. Our custody clients choose to use third-party foreign exchange providers other than BNY Mellon for a substantial majority of their U.S. dollar-equivalent volume foreign exchange transactions.

We typically price negotiated trades for our custody clients at a spread over either our estimation of the current market rate for a particular currency or an agreed upon third-party benchmark. With respect to our standing instruction program, we typically assign a price derived from the daily pricing range for marketable-size foreign exchange transactions (generally more than $1 million) executed between global financial institutions, known as the “interbank range.” Using the interbank range for the given day, we typically price purchases of currencies at or near the low end of this range and sales of currencies at or near the high end of this range. The standing instruction program Defined Spread Offering prices transactions in each pricing cycle (several times a day in the case of developed market currencies) by adding a predetermined spread to an objective market source for developed and certain emerging market currencies or to a reference rate computed by BNY Mellon for other emerging market currencies. A shift by custody clients from the standing

instruction program to other trading options combined with the increasing competitive market pressures on the foreign exchange business may negatively impact our foreign exchange revenue. For the quarter ended March 31, 2013, our total revenue for all types of foreign exchange trading transactions was $149 million, or approximately 4% of our total revenue and approximately 37% of our foreign exchange revenue resulted from foreign exchange transactions undertaken through our standing instruction program.

Distribution and servicing fees

Distribution and servicing fee revenue was $49 million in the first quarter of 2013, $46 million in the first quarter of 2012 and $52 million in the fourth quarter of 2012. The year-over-year increase primarily reflects higher market values. The sequential decrease primarily reflects short-term outflows.

Financing-related fees

Financing-related fees, which are primarily reported in the Other segment, include capital markets fees, loan commitment fees and credit-related fees. Financing-related fees were $41 million in the first quarter of 2013, $44 million in the first quarter of 2012 and $45 million in the fourth quarter of 2012. The decrease from both prior periods was primarily a result of lower capital markets fees.

asset-related gains and losses, lease residual gains, transitional services agreements, gains or losses on seed capital investments, gains and losses on private equity investments, and other income and loss. Expense reimbursements from joint ventures relate to expenses incurred by BNY Mellon on behalf of joint ventures. Asset-related gains (losses) include loan, real estate and other asset dispositions. Transitional services agreements primarily relate to the Shareowner Services business, which was sold on Dec. 31, 2011. Other income (loss) primarily includes foreign currency remeasurement gain (loss), other investments and various miscellaneous revenues. Investment and other income decreased $67 million compared with the first quarter of 2012 and $44 million compared with the fourth quarter of 2012. Both decreases reflect lower leasing gains and lower foreign currency remeasurement.

Additionally, the year-over-year decrease includes lower seed capital gains, and the sequential decrease includes lower net gains on loans held for sale retained from a previously divested bank subsidiary.

Net securities gains

Net securities gains totaled $48 million in the first quarter of 2013, $40 million in the first quarter of 2012 and $50 million in the fourth quarter of 2012. The current low interest rate environment has created the opportunity for us to realize gains as we rebalance and manage the duration risk of the investment securities portfolio. Gains realized on the sales of securities should be considered along with net interest revenue when evaluating our overall results.

Net interest revenue totaled $719 million in the first quarter of 2013, a decrease of $46 million compared with the first quarter of 2012 and $6 million sequentially. The year-over-year decrease was primarily driven by lower accretion, lower yields on the reinvestment of securities and the elimination of interest on European Central Bank deposits, partially offset by a change in the mix of earning assets and higher average interest-earning assets driven by higher deposit levels. The decrease compared with the fourth quarter of 2012 primarily reflects a fewer number of days in the first quarter of 2013.

The net interest margin (FTE) was 1.11% in the first quarter of 2013 compared with 1.32% in the first quarter of 2012 and 1.09% in the fourth quarter of 2012. The year-over-year decrease in the net interest margin (FTE) reflects higher average interest-

earning assets driven by higher deposits levels, lower reinvestment yields, lower accretion and the elimination of interest on European Central Bank deposits.

The current low interest rate environment has continued to negatively impact net interest revenue. However, it has driven significant improvement in the value of the investment securities portfolio while creating the opportunity for us to realize gains as we rebalance and manage the duration risk of this portfolio. Gains realized on these sales should be considered along with net interest revenue when evaluating our overall results. In the first quarter of 2013, combined net interest revenue and net securities gains totaled $767 million compared with $805 million in the first quarter of 2012 and $775 million in the fourth quarter of 2012.

Total noninterest expense increased $72 million, or 3% (unannualized), compared with the first quarter of 2012 and was essentially unchanged compared with the fourth quarter of 2012. Excluding amortization of intangible assets, merger and integration (“M&I”), litigation and restructuring charges, noninterest expense increased 6% year-over-year and 1% (unannualized) sequentially. Both increases were primarily driven by a provision for administrative errors in certain offshore tax-exempt funds and higher pension expense. The increase compared with the first quarter of 2012 also resulted from the cost of generating certain tax credits, higher software and net occupancy expenses and the impact of the Meriten acquisition. The increase compared with the fourth quarter of 2012 also reflects higher incentive and net occupancy expenses, partially offset by lower compensation expense.

Staff expense

Given our mix of fee-based businesses, which are staffed with high-quality professionals, staff expense comprised 54% of total noninterest expense in the first quarter of 2013, 57% in the first quarter of 2012 and 54% in the fourth quarter of 2012, excluding amortization of intangible assets and M&I, litigation and restructuring charges.

Staff expense was $1.5 billion in the first quarter of 2013, an increase of 1% compared with both the first quarter of 2012 and the fourth quarter of 2012. Both increases reflect higher pension expense. The sequential increase also reflects higher incentive expense due to the acceleration of the vesting of long-term stock awards for retirement eligible employees, partially offset by lower compensation expense. The year-over-year increase also includes higher compensation expense, partially offset by lower incentive expense.

Non-staff expense

Non-staff expense, excluding amortization of intangible assets and M&I, litigation and restructuring charges, totaled $1.2 billion in the first quarter of 2013, an increase of 12% compared with the first quarter of 2012 and was flat compared with the fourth quarter of 2012. The year-over-year increase was driven by a provision for administrative errors in certain offshore tax-exempt funds, the cost of generating certain tax credits, higher software and net occupancy expenses. The increase in software expense primarily reflects application development costs and higher amortization related to new technology projects. The increase in net occupancy expense primarily reflects the timing of costs associated with our global footprint and New York

BNY Mellon 12

City real estate initiatives. On a sequential basis, the provision for administrative errors and higher net occupancy expense were primarily offset by lower professional, legal and other purchased services and business development expenses.

The financial services industry has seen a continuing increase in the level of litigation activity. As a result, we anticipate our legal and litigation costs to continue at elevated levels.

For additional information on our legal proceedings, see Note 18 of the Notes to Consolidated Financial Statements.

During the first quarter of 2013, we accomplished the following operational excellence initiatives:

• Continued global footprint position migrations. Lowered operating costs as we ramped up the Eastern European Global Delivery Center.

• Realized savings from reengineering activities relating to Investment Boutique restructurings and Dreyfus back office operations consolidation.

• Achieved further operational synergies related to the BHF Asset Servicing GmbH acquisition.

• Realized compensation savings from efficiencies and additional staff moves to Global Delivery Centers in the Technology organization.

• Consolidated offices and reduced real estate by an additional 35,000 square feet, primarily in the NY Metro and EMEA regions.

Income taxes

BNY Mellon recorded an income tax provision of $1.0 billion in the first quarter of 2013, including the $854 million charge related to the disallowance of certain foreign tax credits. The effective tax rate, on an operating basis - Non-GAAP was 23.7% in the

first quarter of 2013. The provision for income taxes and effective tax rate were $254 million and 28.7%, respectively in the first quarter of 2012 and $207 million and 24.3%, respectively in the fourth quarter of 2012. See “Supplemental information - Explanation of Non-GAAP financial measures” beginning on page 48 for additional information.

We expect the effective tax rate to be approximately 25% to 26% in second quarter of 2013.

Review of businesses

We have an internal information system that produces performance data along product and service lines for our two principal businesses and the Other segment.

Business accounting principles

Our business data has been determined on an internal management basis of accounting, rather than the generally accepted accounting principles used for consolidated financial reporting. These measurement principles are designed so that reported

13 BNY Mellon

results of the businesses will track their economic performance.

For information on the accounting principles of our businesses, the primary types of revenue by business and how our businesses are presented and analyzed, see Note 19 of the Notes to Consolidated Financial Statements.

Business results are subject to reclassification whenever improvements are made in the measurement principles or when organizational changes are made. In the first quarter of 2013, incentive expense related to restricted stock and certain corporate overhead charges were allocated to the Investment Management and Investment Services businesses that had been previously included in the Other segment. All prior periods were restated to reflect these changes. Additionally, the results of the businesses for the first quarter of 2013 reflect higher internal crediting rates for

domestic deposits, which are regularly updated to reflect the value of deposit balances and distribution of overall interest revenue. These changes did not impact the consolidated results.

The results of our businesses may be influenced by client activities that vary by quarter. In the second quarter, we typically experience an increase in securities lending fees due to an increase in demand to borrow securities outside of the United States. In the third quarter, Depositary Receipts revenue is typically higher due to an increased level of client dividend payments paid in the quarter. Also in the third quarter, volume-related fees may decline due to reduced client activity. In our Investment Management business, performance fees are typically higher in the fourth quarter, as the fourth quarter represents the end of the measurement period for many of the performance fee-eligible relationships.

Fee revenue in Investment Management, and to a lesser extent in Investment Services, is impacted by the value of market indices. At March 31, 2013, using the Standard & Poor’s (“S&P”) 500 Index as a proxy for the global equity markets, we estimate that a 100-point change in the value of the S&P 500

Index spread evenly throughout the year, would impact fee revenue by less than 1% and diluted earnings per common share by $0.03 to $0.05. If however, global equity markets do not perform in line with the S&P 500 Index, the impact to fee revenue and earnings per share could be different.

Business description

Our Investment Management business is comprised of our affiliated investment management boutiques, wealth management business and global distribution companies. See page 22 of our 2012 Annual Report for additional information on our Investment Management business.

Review of financial results

Investment management and performance fees are dependent on the overall level and mix of AUM and the management fees expressed in basis points (one-hundredth of one percent) charged for managing those assets. Assets under management were a record $1.43 trillion at March 31, 2013 compared with $1.31 trillion at March 31, 2012 and $1.39 trillion at Dec. 31, 2012. The increases compared with both periods primarily resulted from net new business and higher market values. Net long-term inflows were a record $40 billion in the first quarter of 2013 and benefited from liability-driven investments as well as equity and fixed income funds. Net short-term outflows were $13 billion in the first quarter of 2013.

Revenue generated in the Investment Management business included 44% from non-U.S. sources in the first quarter of 2013 compared with 45% in the first quarter of 2012 and 47% in the fourth quarter of 2012.

In the first quarter of 2013, Investment Management had pre-tax income of $211 million compared with $237 million in the first quarter of 2012 and $226 million in the fourth quarter of 2012. Excluding amortization of intangible assets, pre-tax income was $250 million in the first quarter of 2013 compared with $285 million in the first quarter of 2012 and $274 million in the fourth quarter of 2012. Both decreases were impacted by a provision for administrative errors in certain offshore tax-exempt funds in the first quarter of 2013, which more than offset higher investment management fees.

Investment management fees in the Investment Management business were $812 million in first quarter of 2013 compared with $739 million in the first quarter of 2012 and $801 million in the fourth quarter of 2012. The year-over-year increase was impacted by the Meriten acquisition. Excluding the Meriten acquisition, investment management fees

increased 8% year-over-year driven by higher market values, net new business and lower money market fee waivers. The sequential increase primarily reflects higher market values, partially offset by higher money market fee waivers. Comparisons to both prior periods were negatively impacted by the stronger U.S. dollar.

Performance fees were $15 million in the first quarter of 2013 compared with $16 million in the first quarter of 2012 and $57 million in the fourth quarter of 2012. The sequential decrease was due to seasonality.

In the first quarter of 2013, 36% of investment management fees in the Investment Management business were generated from managed mutual fund fees. These fees are based on the daily average net assets of each fund and the management fee paid by that fund. Managed mutual fund fee revenue was $295 million in the first quarter of 2013 compared with $260 million in the first quarter of 2012 and $293 million in the fourth quarter of 2012. The increases compared with both prior periods primarily resulted from net new business and higher market values.

Distribution and servicing fees were $46 million in the first quarter of 2013 compared with $45 million in the first quarter of 2012 and $50 million in the fourth quarter of 2012. The year-over-year increase primarily reflects higher market values. The sequential decrease primarily reflects short-term outflows.

Other fee revenue was $21 million in the first quarter of 2013 compared with $52 million in the first quarter of 2012 and $25 million in the fourth quarter of 2012. The year-over-year decrease primarily reflects lower seed capital gains.

Net interest revenue was $62 million in the first quarter of 2013 compared with $55 million in both the first quarter of 2012 and fourth quarter of 2012. Both increases resulted from higher average loan and deposit levels. The sequential increase also resulted from higher internal crediting rates for domestic deposits in the first quarter of 2013. Average loans increased 21% year-over-year and 6% sequentially, while average deposits increased 19% year-over-year and 8% sequentially.

17 BNY Mellon

Noninterest expense excluding amortization of intangible assets was $706 million in the first quarter of 2013 compared with $622 million in the first quarter of 2012 and $714 million in the fourth quarter of 2012. Noninterest expense in the first quarter of 2013 includes a provision for administrative errors in certain offshore tax-exempt funds. The year-over-year increase also reflects the

impact of the Meriten acquisition. The sequential decrease also reflects lower incentive expense due to seasonally lower performance fees, as well as lower professional, legal and other purchased services and seasonally lower business development expenses. Comparisons to both prior periods were favorably impacted by the stronger U.S. dollar.

Business description

Our Investment Services business provides global custody and related services, broker-dealer services, collateral services, alternative investment services, corporate trust and depositary receipt services, as well as clearing services and global payment/working capital solutions to institutional clients.

Our comprehensive suite of financial solutions includes: global custody, global fund services, securities lending, investment manager outsourcing, performance and risk analytics, alternative investment services, securities clearance, collateral management, corporate trust, American and global depositary receipt programs, cash management solutions, payment services, liquidity services and other linked revenues, principally foreign exchange, global clearing and execution, managed account services and global prime brokerage solutions. Our clients include corporations, public funds and government agencies, foundations and endowments; global financial institutions including banks, broker-dealers, asset managers, insurance companies and central banks; financial intermediaries and independent registered investment advisors and hedge fund managers. We help our clients service their financial assets through a network of offices and operations centers in 36 countries across six continents.

The results of this business are driven by a number of factors which include: the level of transaction activity; the range of services provided, including custody, accounting, fund administration, daily valuations, performance measurement and risk analytics, securities lending, and investment manager back-office outsourcing; the number of accounts; and the market value of assets under custody and/or administration. Market interest rates impact both securities lending revenue and the earnings on client deposit balances. Business expenses are driven by staff, technology investment, equipment and space required to support the services provided by the business and the cost of execution, clearance and custody of securities.

We are one of the leading global securities servicing providers with $26.3 trillion of assets under custody and/or administration at March 31, 2013. We are the largest custodian for U.S. corporate and public pension plans and we service 46% of the top 50 endowments. We are a leading custodian in the UK

and service 20% of UK pensions that require a custodian. Globalization tends to drive cross-border investment and capital flows, which increases the opportunity to provide solutions to our clients. The changing regulatory environment is also driving demand for new products and services among clients.

BNY Mellon is a leader in both global securities and U.S. Government securities clearance. We clear and settle equity and fixed income transactions in over 100 markets and handle most of the transactions cleared through the Federal Reserve Bank of New York for 17 of the 21 primary dealers. We are a leader in servicing tri-party repo collateral with approximately $2.1 trillion globally. We currently service approximately $1.5 trillion of the $1.8 trillion tri-party repo market in the U.S.

BNY Mellon offers tri-party agent services to dealers and cash investors active in the tri-party repurchase, or tri-party repo, market. We currently have an approximately 80% market share of the U.S. tri-party repo market. As a tri-party repo agent, we facilitate settlement between dealers (cash borrowers) and investors (cash lenders). Our involvement in a transaction commences after a dealer and a cash investor agree to a tri-party repo trade and send instructions to us. We maintain custody of the collateral (the subject securities of the repo) and execute the payment and delivery instructions agreed to and provided by the principals.

BNY Mellon is working to significantly reduce the risk associated with the secured intraday credit we provide with respect to the tri-party repo market. BNY Mellon has implemented several measures in that regard, including reducing the amount of time we extend intraday credit, implementing three-way trade confirmations, and automating the way dealers can substitute collateral in their tri-party repo trades. Additionally, in 2013, we have limited the eligibility for intraday credit associated with tri-party repo transactions to certain more liquid asset classes that will result in a reduction of exposures secured by less liquid forms of collateral by dealers. These efforts are consistent with the recommendations of the Tri-Party Repo Infrastructure Reform Task Force that was sponsored by the Payments Risk Committee of the Federal Reserve Bank of New York and included representatives from a diverse group of market participants, including BNY Mellon. We anticipate that the combination of these measures

BNY Mellon 20

will reduce risks substantially in our tri-party repo activity in the near term and, together with technology enhancements currently in development, will achieve the practical elimination of intraday credit in this activity by the end of 2014.

Since May 2010, the Federal Reserve Bank of New York has released monthly reports on the tri-party repo market, including information on aggregate volumes of collateral used in all tri-party repo transactions by asset class, concentrations, and margin levels, which is available at http://www.newyorkfed.org/banking/tpr_infr_reform.html.

In 2012, we formed Global Collateral Services which serves broker-dealers and institutional investors facing expanding collateral management needs as a result of current and emerging regulatory and market requirements. Global Collateral Services brings together BNY Mellon’s global capabilities in segregating, optimizing, financing and transforming collateral on behalf of clients, including its market leading broker-dealer collateral management, securities lending, collateral financing, liquidity and derivatives services teams.

In securities lending, we are one of the largest lenders of U.S. Treasury securities and depositary receipts and service a lending pool of approximately $3 trillion in 30 markets.

We serve as depositary for 1,359 sponsored American and global depositary receipt programs at March 31, 2013, acting in partnership with leading companies from 64 countries - an estimated 59% global market share.

Pershing and its affiliates provide business solutions to approximately 1,600 financial organizations globally by delivering dependable operational support; robust trading services; flexible technology; an expansive array of investment solutions, practice management support and service excellence.

Role of BNY Mellon, as a trustee, for mortgage-backed securitizations

BNY Mellon acts as trustee and document custodian for certain mortgage-backed security (“MBS”) securitization trusts. The role of trustee for MBS securitizations is limited; our primary role as trustee is to calculate and distribute monthly bond payments to bondholders. As a document custodian, we hold

the mortgage, note, and related documents provided to us by the loan originator or seller and provide periodic reporting to these parties. BNY Mellon, either as document custodian or trustee, does not receive mortgage underwriting files (the files that contain information related to the creditworthiness of the borrower). As trustee or custodian, we have no responsibility or liability for the quality of the portfolio; we are liable only for performance of our limited duties as described above and in the trust documents. BNY Mellon is indemnified by the servicers or directly from trust assets under the governing agreements. BNY Mellon may appear as the named plaintiff in legal actions brought by servicers in foreclosure and other related proceedings because the trustee is the nominee owner of the mortgage loans within the trusts.

Review of financial results

AUC/A at March 31, 2013 were $26.3 trillion, an increase of 2% from $25.7 trillion at March 31, 2012 and unchanged from Dec. 31, 2012. The year-over-year increase was driven by net new business and improved market values, partially offset by the impact of changes in foreign currency rates. Sequentially, improved market values were offset by the impact of changes in foreign currency rates, while net new business was flat. AUC/A were comprised of 33% equity securities and 67% fixed income securities at both March 31, 2013 and Dec. 31, 2012.

Income before taxes was $685 million in the first quarter of 2013 compared with $629 million in the first quarter of 2012 and $526 million in the fourth quarter of 2012. Income before taxes, excluding amortization of intangible assets, was $732 million in the first quarter of 2013 compared with $677 million in the first quarter of 2012 and $574 million in the fourth quarter of 2012. The increase compared with the first quarter of 2012 primarily reflects higher asset servicing fees and lower noninterest expense. The increase sequentially was driven by higher net interest revenue, foreign exchange revenue, issuer services fees and asset servicing fees.

Revenue generated in the Investment Services business included 32% from non-U.S. sources in the first quarter of 2013 compared with 36% in the first quarter of 2012 and 34% in the fourth quarter of 2012.

21 BNY Mellon

Investment services fees increased $22 million, or 1%, in the first quarter of 2013 compared with the first quarter of 2012 and $54 million, or 3% (unannualized), compared with the fourth quarter of 2012, reflecting the following factors:

• Asset servicing fees (global custody, broker-dealer services and global collateral services) were $938 million in the first quarter of 2013 compared with $906 million in the first quarter of 2012 and $917 million in the fourth quarter of 2012 . Both increases primarily reflect increased activity with existing clients and improved market values. The year-over-year increase was partially offset by lower securities lending revenue due to lower spreads and the loss of a client.

• Issuer services fees (Corporate Trust and Depositary Receipts) were $236 million in the first quarter of 2013, compared with $251 million in the first quarter of 2012 and $213 million in the fourth quarter of 2012. The year-over-year decrease primarily resulted from lower Depositary Receipts revenue, driven by lower issuance volumes and lower servicing fees. The sequential increase primarily resulted from higher Depositary Receipts revenue driven by an improvement in dividends and higher core volumes, partially offset by lower Corporate Trust revenue.

• Clearing services fees (Pershing) were $304 million in the first quarter of 2013 compared with $303 million in the first quarter of 2012 and $294 million in the fourth quarter of 2012. Both increases were driven by higher mutual fund fees, increases in positions and assets, higher cash management fees and an increase in DARTS, partially offset by higher money market fee waivers and fewer trading days.

• Treasury services fees were $140 million in the first quarter of 2013 compared with $136 million in the first quarter of 2012 and $140 million in the fourth quarter of 2012. The year-over-year increase primarily reflects higher cash management fees.

Foreign exchange and other trading revenue was $172 million in the first quarter of 2013, compared with $176 million in the first quarter of 2012 and $128 million in the fourth quarter of 2012. The year-over year decrease resulted from lower fixed income trading revenue which was primarily offset by higher foreign exchange revenue driven by higher

volumes, partially offset by a decrease in volatility. The sequential increase was due to higher foreign exchange revenue resulting from increased volatility and higher volumes.

Net interest revenue was $653 million in the first quarter of 2013 compared with $648 million in the first quarter of 2012 and $591 million in the fourth quarter of 2012. Both increases primarily reflect higher internal crediting rates for domestic deposits in the first quarter of 2013 and higher average loan levels.

Noninterest expense, excluding amortization of intangible assets, remained steady at $1.8 billion in the first quarter of 2013, the first quarter of 2012 and the fourth quarter of 2012. Year-over-year, noninterest expense decreased slightly reflecting lower litigation expense. Sequentially, noninterest expense was essentially unchanged as higher incentive expense due to the acceleration of the vesting of long-term stock awards for retirement-eligible employees was offset by lower professional, legal and other purchased services and business development expenses.

Review of financial results

The Other segment incurred a pre-tax loss of $103 million in first quarter of 2013 compared with income of $8 million in first quarter of 2012 and income of $90 million in the fourth quarter of 2012.

Total fee and other revenue decreased $51 million compared with the first quarter of 2012 and $59 million compared with the fourth quarter of 2012. Both decreases reflect lower leasing gains and lower foreign currency remeasurement. The sequential decrease was also due to lower net gains on loans held-for-sale retained from a previously divested bank subsidiary as well as lower fixed income and equity trading revenue.

Net interest revenue decreased $58 million compared with the first quarter of 2012 and $75 million compared with the fourth quarter of 2012. Both decreases reflect higher internal crediting rates to the businesses for domestic deposits in the first quarter of 2013.

The provision for credit losses was a credit of $24 million in the first quarter of 2013. Approximately half of the credit was driven by a broad improvement in the credit quality of the loan portfolio and the other half related to a reduction in our qualitative allowance.

Noninterest expense (excluding M&I and restructuring charges) increased $19 million compared with the first quarter of 2012 and $44 million compared with the fourth quarter of 2012. The year-over-year increase resulted from the cost of

generating certain tax credits as well as higher software and net occupancy expenses, partially offset by lower incentive expense. Sequentially, the increase primarily reflects higher incentive expense due to the acceleration of the vesting of long-term stock awards for retirement eligible employees as well as higher pension and net occupancy expenses.

Consolidated balance sheet review

At March 31, 2013, total assets were $356 billion compared with $359 billion at Dec. 31, 2012. Total assets averaged $334 billion in the first quarter of 2013 compared with $301 billion in the first quarter of 2012 and $336 billion in the fourth quarter of 2012. Fluctuations in the period-end and average total assets were primarily driven by the level of client deposits. Deposits totaled $240 billion at March 31, 2013, and $246 billion at Dec. 31, 2012. Total deposits averaged $218 billion in the first quarter of 2013, $192 billion in the first quarter of 2012 and $223 billion in the fourth quarter of 2012. At March 31, 2013, total interest-bearing deposits were 55% of total interest-earning assets compared with 52% at Dec. 31, 2012.

At March 31, 2013, we had $48 billion of liquid funds and $82 billion of cash (including $78 billion of overnight deposits with the Federal Reserve and other central banks) for a total of $130 billion of available funds. This compares with available funds of $145 billion at Dec. 31, 2012. The decrease in available funds resulted from a lower level of client deposits and by the redeployment of funds on our balance sheet from interest-bearing deposits with the Federal Reserve and other central banks as we increased our investment in high-quality securities and the loan portfolio. Our percentage of available funds to total assets was 37% at March 31, 2013 compared with 40% at Dec. 31, 2012. Of the $48 billion in liquid funds held at March 31, 2013, $41 billion was placed in interest-bearing deposits with large, highly-rated global financial institutions with a weighted-average life to maturity of approximately 59 days. Of the $41 billion, $7 billion was placed with banks in the Eurozone.

Investment securities were $107 billion or 30% of total assets at March 31, 2013, compared with $101 billion or 28% of total assets at Dec. 31, 2012. The increase primarily reflects larger investments in agency RMBS and U.S. Treasury securities.

Trading assets were $12 billion at March 31, 2013 compared with $9 billion at Dec. 31, 2012. The increase in trading assets resulted from higher levels of securities inventory, principally U.S. Government, agency mortgage-backed and U.S. equities, as we expand our broker-dealer business.

Loans were $49 billion or 14% of total assets at March 31, 2013, compared with $47 billion or 13% of total assets at Dec. 31, 2012. The increase in loan levels primarily reflects higher loans to financial institutions.

Long-term debt increased to $19.9 billion at March 31, 2013 from $18.5 billion at Dec. 31, 2012. We issued $1.5 billion of senior debt in the first quarter of 2013 in anticipation of $1.6 billion of maturities in the remainder of 2013.

Total The Bank of New York Mellon Corporation’s shareholders’ equity was $35.7 billion at March 31, 2013 and $36.4 billion at Dec. 31, 2012. The decrease primarily reflects the net loss recorded in the first quarter of 2013, share repurchases and a slight decrease in the valuation of the investment securities portfolio.

Exposure in Ireland, Italy, Spain, Portugal and Greece

The following tables present our on- and off-balance sheet exposure in Ireland, Italy and Spain at March 31, 2013 and Dec. 31, 2012. We have provided expanded disclosure on these countries as they have experienced particular market focus on credit quality and are countries experiencing economic concerns. Where appropriate, we are offsetting the risk associated with the gross exposure in these countries with collateral that has been pledged, which primarily consists of cash or marketable securities, or by transferring the risk to a third-party guarantor in another country.

BNY Mellon has a limited economic interest in the performance of assets of consolidated investment management funds, and therefore they are excluded from this presentation. The liabilities of consolidated investment management funds represent the interest of the noteholders of the funds and are solely dependent on the value of the assets. Any loss in the value of assets of consolidated investment management funds would be incurred by the fund’s noteholders.

At March 31, 2013 and at Dec. 31, 2012, BNY Mellon had exposure of less than $1 million in Portugal and no exposure in Greece. Additionally, BNY Mellon had no sovereign exposure to the countries disclosed below at either March 31, 2013 or Dec. 31, 2012.

Our exposure in Ireland is principally related to Irish domiciled investment funds. Servicing provided to these funds and fund families may result in overdraft exposure.

Investment securities

In the discussion of our investment securities portfolio, we have included certain credit ratings information because the information indicates the degree of credit risk to which we are exposed, and significant changes in ratings classifications for our

investment portfolio could indicate increased credit risk for us and could be accompanied by a reduction in the fair value of our investment securities portfolio.

The following table shows the distribution of our total investment securities portfolio:

(a) Amortized cost before impairments.

(b) Primarily comprised of exposure to UK, Germany, Netherlands and France.

(c) These RMBS were included in the former Grantor Trust and were marked-to-market in 2009. We believe these RMBS would receive higher credit ratings if these ratings incorporated, as additional credit enhancement, the difference between the written-down amortized cost and the current face amount of each of these securities.

(d) Includes RMBS, commercial MBS and other securities. Primarily comprised of exposure to UK and Netherlands.

(e) Primarily comprised of exposure to Canada, UK and Germany.

(f) Includes commercial paper of $2.2 billion and $2.2 billion, fair value, and money market funds of $2.2 billion and $2.5 billion, fair value, at Dec. 31, 2012 and March 31, 2013, respectively.

(g) Includes net unrealized losses on derivatives hedging securities available-for-sale of $305 million at Dec. 31, 2012 and $111 million at March 31, 2013.

The fair value of our investment securities portfolio was $106.6 billion at March 31, 2013 compared with $100.7 billion at Dec. 31, 2012. The increase in the fair value of the investment securities portfolio primarily reflects larger investments in agency RMBS and U.S. Treasury securities, partially offset by a decrease in the unrealized gain of our investment securities. In the first quarter of 2013, we received $183 million of paydowns and sold $141 million of sub-investment grade securities.

At March 31, 2013, the total investment securities portfolio had a net unrealized pre-tax gain of $2.2 billion compared with $2.4 billion at Dec. 31, 2012. The decline in the valuation of the investment securities portfolio was primarily driven by an

increase in market interest rates and $48 million of net realized securities gains in the first quarter of 2013. The unrealized net of tax gain on our investment securities available-for-sale portfolio included in accumulated other comprehensive income was $1.2 billion at March 31, 2013, compared with $1.3 billion at Dec. 31, 2012.

At March 31, 2013 and Dec. 31, 2012, 89% of the securities in our portfolio were rated AAA/AA-.

We routinely test our investment securities for OTTI. (See “Critical accounting estimates” for additional disclosure regarding OTTI.)

At March 31, 2013, we had $789 million of accretable discount related to the restructuring of the investment securities portfolio. These restructured securities had a remaining average life of approximately 5.6 years. The accretion of discount related to these securities increased net interest revenue and was recorded on a level yield basis. The discount accretion totaled $57 million in the first quarter of 2013, $80 million in the first quarter of 2012 and $60 million in fourth quarter of 2012.

Also, at March 31, 2013, we had $2.7 billion of net amortizable purchase premium relating to investment securities with a remaining average life of approximately 4.6 years. For these securities, the amortization of net premium decreased net interest revenue and was recorded on a level yield basis. We recorded net premium amortization of $140 million in the first quarter of 2013, $111 million in the first quarter of 2012 and $138 million in the fourth quarter of 2012.

On a quarterly basis, we perform our impairment analysis using several factors, including projected loss severities and default rates. In the first quarter of 2013, this analysis resulted in $4 million of credit losses primarily on Alt-A, prime and subprime RMBS. If we were to increase or decrease each of our projected loss severities and default rates by 100 basis points on each of the positions in our Alt-A, subprime and prime RMBS portfolios, including the securities previously held by the Grantor Trust, credit-related impairment charges on these securities would have increased by $1 million (pre-tax) or decreased by $1 million (pre-tax) at March 31, 2013. See Note 4 of the Notes to Consolidated Financial Statements for the projected weighted-average default rates and loss severities.

At March 31, 2013, the investment securities portfolio included $34 million of assets not accruing interest. These securities are held at market value.

The following table shows the fair value of the European floating rate notes by geographical location at March 31, 2013. The unrealized loss on these securities was $99 million at March 31, 2013, an improvement of $22 million compared with $121 million at Dec. 31, 2012.

At March 31, 2013, total exposures were $88.0 billion, an increase of 3% from $85.3 billion at Dec. 31, 2012. The increase in total exposure primarily reflects higher loans in the financial institutions portfolio.

Our financial institutions and commercial portfolios comprise our largest concentrated risk. These portfolios make up 56% of our total lending exposure. Additionally, a substantial portion of our overdrafts relate to financial institutions and commercial customers.

The financial institutions portfolio exposure was $29.3 billion at March 31, 2013 compared with $27.0 billion at Dec. 31, 2012. The increase primarily reflects higher exposure to banks, driven by a higher level of trade finance loans.

Financial institution exposures are high quality, with 93% of the exposures meeting the investment grade equivalent criteria of our internal credit rating classification at March 31, 2013. Each customer is assigned an internal credit rating, which is mapped to an equivalent external rating agency grade based upon a number of dimensions which are continually

evaluated and may change over time. The exposure to financial institutions is generally short-term. Of these exposures, 71% expire within one year, and 40% expire within 90 days. In addition, 38% of the financial institutions exposure is secured. For example, securities industry and asset managers often borrow against marketable securities held in custody.

For ratings of non-U.S. counterparties, as a conservative measure, our internal credit rating is generally capped at a rating equivalent to the sovereign rating of the country where the

29 BNY Mellon

counterparty resides regardless of the internal credit rating assigned to the counterparty or the underlying collateral.

Our bank exposure primarily relates to our global trade finance and U.S. dollar-clearing businesses. These exposures are predominately to investment grade counterparties and are short term in nature.

The asset manager portfolio exposures are high- quality, with 99% of the exposures meeting our investment grade equivalent ratings criteria as of March 31, 2013. These exposures are generally short-term liquidity facilities, with the vast majority to regulated mutual funds.

Commercial

The diversity of the commercial portfolio is shown in the following table.

Commercial portfolio exposure	March 31, 2013										Dec. 31, 2012
(dollar amounts in billions)	Loans		Unfunded commitments		Total exposure		% Inv grade		% due <1 yr		Loans		Unfunded commitments		Total exposure

Total	$	1.5	$	18.7	$	20.2	94	%	11	%	$	1.4	$	18.3	$	19.7

The commercial portfolio exposure increased 3% to $20.2 billion at March 31, 2013, from $19.7 billion at Dec. 31, 2012, primarily reflecting an increase in exposure to the energy and utilities and the services and other portfolios.

Our goal is to maintain a predominantly investment grade portfolio. The table below summarizes the percent of the financial institutions and commercial exposures that are investment grade.

Percentage of the portfolios that are investment grade
	March 31, 2012		June 30, 2012		Sept. 30, 2012		Dec. 31, 2012		March 31, 2013
Financial institutions	92	%	92	%	93	%	93	%	93	%
Commercial	92	%	93	%	93	%	93	%	94	%

Our credit strategy is to focus on investment grade names to support cross-selling opportunities and avoid single name/industry concentrations. The execution of our strategy has resulted in 93% of our financial institutions portfolio and 94% of our commercial portfolio rated as investment grade at March 31, 2013.

Wealth management loans and mortgages

Our Wealth management exposure was $10.8 billion at March 31, 2013 compared with $10.6 billion at

Dec. 31, 2012. Wealth management loans and mortgages are primarily comprised of loans to high-net-worth individuals, which are secured by marketable securities and/or residential property. Wealth management mortgages are primarily interest-only adjustable rate mortgages with an average loan to value ratio of 63% at origination. In the wealth management portfolio, less than 1% of the mortgages were past due at March 31, 2013.

At March 31, 2013, the wealth management mortgage portfolio was comprised of the following geographic concentrations: New York - 22%; California - 20%; Massachusetts - 16%; Florida - 8%; and other - 34%.

Commercial real estate

Our commercial real estate facilities are focused on experienced owners and are structured with moderate leverage based on existing cash flows. Our commercial real estate lending activities include both construction facilities and medium-term loans. Our client base consists of experienced developers and long-term holders of real estate assets. Loans are approved on the basis of existing or projected cash flow, and supported by appraisals and knowledge of local market conditions. Development loans are structured with moderate leverage, and in most instances, involve some level of recourse to the developer. Our commercial real estate exposure

BNY Mellon 30

totaled $3.9 billion at March 31, 2013 compared with $3.6 billion at Dec. 31, 2012.

At March 31, 2013, 58% of our commercial real estate portfolio is secured. The secured portfolio is diverse by project type, with 54% secured by residential buildings, 15% secured by office buildings, 12% secured by retail properties, and 19% secured by other categories. Approximately 98% of the unsecured portfolio is allocated to investment grade real estate investment trusts (“REITs”) under revolving credit agreements.

At March 31, 2013, our commercial real estate portfolio is comprised of the following concentrations: New York metro - 46%; investment grade REITs - 41%; and other - 13%.

Lease financings

The leasing portfolio exposure totaled $2.3 billion and included $185 million of airline exposures at March 31, 2013, compared with $2.4 billion of leasing exposures, including $191 million of airline exposures, at Dec. 31, 2012. At March 31, 2013, approximately 85% of the leasing exposure was investment grade.

At March 31, 2013, the $2.1 billion non-airline lease financing portfolio consisted of exposures backed by well-diversified assets, primarily large-ticket transportation equipment.

At March 31, 2013, our $185 million of exposure to the airline industry consisted of $68 million to major U.S. carriers, $99 million to foreign airlines and $18 million to U.S. regional airlines.

Despite the significant improvement in revenues and yields that the U.S domestic airline industry achieved, high fuel prices pose a significant challenge for these carriers. Combined with their high fixed cost operating models, extremely high debt levels and sensitivity to economic cycles, the domestic airlines remain vulnerable. Accordingly, we continue to maintain a sizable allowance for loan losses against these exposures and continue to closely monitor the portfolio.

We utilize the lease financing portfolio as part of our tax management strategy.

Other residential mortgages

The other residential mortgage portfolio primarily consists of 1-4 family residential mortgage loans and totaled $1,570 million at March 31, 2013, compared with $1,632 million at Dec. 31, 2012. Included in this portfolio at March 31, 2013 are $480 million of mortgage loans purchased in 2005, 2006 and the first quarter of 2007 that are predominantly prime mortgage loans, with a small portion of Alt-A loans. As of March 31, 2013, the purchased loans in this portfolio had a weighted-average loan-to-value ratio of 75% at origination and 23% of these loans were at least 60 days delinquent. The properties securing the prime and Alt-A mortgage loans were located (in order of concentration) in California, Florida, Virginia, Maryland and the tri-state area (New York, New Jersey and Connecticut).

To determine the projected loss on the prime and Alt-A mortgage portfolio, we calculate the total estimated defaults of these mortgages and multiply that amount by an estimate of realizable value upon sale in the marketplace (severity).

At March 31, 2013, we had $12 million in subprime mortgages included in the other residential mortgage portfolio. The subprime loans were issued to support our Community Reinvestment Act requirements.

Overdrafts

Overdrafts primarily relate to custody and securities clearance clients. Overdrafts occur on a daily basis in the custody and securities clearance business and are generally repaid within two business days.

Other loans

Other loans primarily included loans to consumers that are fully collateralized with equities, mutual funds and fixed income securities, as well as bankers’ acceptances.

Margin loans

Margin loans are collateralized with marketable securities and borrowers are required to maintain a daily collateral margin in excess of 100% of the value of the loan. Margin loans included $5.1 billion of loans at both March 31, 2013 and Dec. 31,

31 BNY Mellon

2012 related to a term loan program that offers fully collateralized loans to broker-dealers.

Asset quality and allowance for credit losses

Over the past several years, we have improved our risk profile through greater focus on clients who are active users of our non-credit services, de-emphasizing broad-based loan growth. Our primary exposure to the credit risk of a customer consists of funded loans, unfunded formal contractual commitments to lend, standby letters of credit and overdrafts associated with our custody and securities clearance businesses.

The role of credit has shifted to one that complements our other services instead of as a lead product. Credit solidifies customer relationships and, through a disciplined allocation of capital, can earn acceptable rates of return as part of an overall relationship.

The following table details changes in our allowance for credit losses.

Allowance for credit losses activity (dollar amounts in millions)	March 31, 2013			Dec. 31, 2012			March 31, 2012
Margin loans	$	13,242		$	13,397		$	13,144
Non-margin loans	35,982			33,232			29,884

Total allowance for credit losses as a percentage of non-margin loans	0.99		%	1.16		%	1.65		%

Net charge-offs were $5 million in the first quarter of 2013 and $8 million in both the first quarter of 2012 and fourth quarter of 2012. Net charge-offs in these periods primarily reflect charge-offs in the other residential mortgage portfolio. Net charge-offs in the fourth quarter of 2012 also included $5 million in the financial institutions portfolio.

The provision for credit losses was a credit of $24 million in the first quarter of 2013. Approximately half of this credit was driven by a broad improvement in the credit quality of the loan portfolio and half related to a reduction in our qualitative allowance. The provision for credit losses was $5 million in the first quarter of 2012 and a credit of $61 million in the fourth quarter of 2012. We anticipate the provision for credit losses to be approximately zero in the second quarter of 2013.

Given the continuing improvement in housing prices, the improved demand in major U.S. housing markets, and the improvement in the majority of the internal and environmental risk factors tracked in our qualitative framework, management concluded a reduction in the qualitative allowance in the first quarter of 2013 was appropriate. Management believes our quantitative allowance and reduced level of qualitative allowance adequately reflects incurred losses associated with the aggregate risk at this stage of the economic recovery.

The total allowance for credit losses was $358 million at March 31, 2013 and $387 million at Dec. 31, 2012. The decrease in the allowance for credit losses was primarily driven by the factors mentioned above.

The ratio of the total allowance for credit losses to non-margin loans was 0.99% at March 31, 2013, 1.16% at Dec. 31, 2012 and 1.65% at March 31, 2012. The ratio of the allowance for loan losses to non-margin loans was 0.66% at March 31, 2013 compared with 0.80% at Dec. 31, 2012 and 1.29% at March 31, 2012. The lower ratios at March 31, 2013 compared with both prior periods primarily reflect the decrease in the allowance for credit losses driven by the broad improvement in the credit quality of the loan portfolio.

BNY Mellon 32

We had $13.2 billion of secured margin loans on our balance sheet at March 31, 2013 compared with $13.4 billion at Dec. 31, 2012 and $13.1 billion at March 31, 2012. We have rarely suffered a loss on these types of loans and do not allocate any of our allowance for credit losses to them. As a result, we believe that the ratio of total allowance for credit losses to non-margin loans is a more appropriate metric to measure the adequacy of the reserve.

The allowance for loan losses and allowance for lending-related commitments represent management’s estimate of probable losses inherent in our credit portfolio. This evaluation is subject to numerous estimates and judgments.

We utilize a quantitative methodology and qualitative framework for determining the allowance for loan losses and the allowance for lending-related commitments. Within this qualitative framework, management applies judgment when assessing internal risk factors and environmental factors to compute an additional allowance for each component of the loan portfolio.

The three elements of the allowance for loan losses and the allowance for lending-related commitments include the qualitative allowance framework. The three elements are:

• an allowance for impaired credits of $1 million or greater;

• an allowance for higher risk-rated credits and pass-rated credits; and

• an allowance for residential mortgage loans.

Our lending is primarily to institutional customers. As a result, our loans are generally larger than $1 million. Therefore, the first element, impaired credits, is based on individual analysis of all impaired loans of $1 million or greater. The allowance is measured by the difference between the recorded value of impaired loans and their impaired value. Impaired value is either the present value of the expected future cash flows from the borrower, the market value of the loan, or the fair value of the collateral.

The second element, higher risk-rated credits and pass-rated credits, is based on our probable loss model. All borrowers are assigned to pools based on their internal credit rating. The probable loss inherent in each loan in a pool incorporates the

borrower’s credit rating, loss given default rating and maturity. The loss given default incorporates a recovery expectation. The borrower’s probability of default is derived from the associated credit rating. Borrower ratings are reviewed at least annually and are periodically mapped to third-party databases, including rating agency and default and recovery databases, to ensure ongoing consistency and validity. Higher risk-rated credits are reviewed quarterly. All loans over $1 million are individually analyzed before being assigned a credit rating.

The third element, the allowance for residential mortgage loans, is determined by segregating six mortgage pools into delinquency periods ranging from current through foreclosure. Each of these delinquency periods is assigned a probability of default. A specific loss given default is assigned for each mortgage pool. All residential mortgage pools, except home equity lines of credit, are assigned a probability of default and loss given default based on five years of default and loss data derived from our residential mortgage portfolio. For each pool, the inherent loss is calculated using the above factors. The resulting probable loss factor (the probability of default multiplied by the loss given default) is applied against the loan balance to determine the allowance held for each pool. For home equity lines of credit, probability of default and loss given default are based on external data from third party databases due to the small size of the portfolio and insufficient internal data.

The qualitative framework is used to determine an additional allowance for each portfolio based on the factors below:

Internal risk factors:

• Nonperforming loans to total non-margin loans;

• Criticized assets to total loans and lending-related commitments;

• Ratings volatility;

• Borrower concentration; and

• Significant concentration in high risk industries.

Environmental risk factors:

• U.S. non-investment grade default rate;

• Unemployment rate; and

• Change in real GDP (quarter over quarter).

The objective of the qualitative framework is to capture incurred losses that may not have been fully captured in the quantitative reserve, which is based primarily on historical data. Management determines the qualitative allowance each period based on judgment informed by consideration of internal and external risk factors. Once determined in the aggregate, our qualitative allowance is then allocated to each of our loan classes based on the respective classes’ quantitative allowance balances with the allocations adjusted, when necessary, for class specific risk factors.

For each risk factor, we calculate the minimum and maximum values, and percentiles in-between, to evaluate the distribution of our historical experience. The distribution of historical experience is compared to the risk factor’s current quarter observed experience to assess the current risk inherent in the portfolio and overall direction/trend of a risk factor relative to our historical experience.

Based on this analysis, we assign a risk level – no impact, low, moderate, high and elevated – to each risk factor for the current quarter. Management assesses the impact of each risk factor to determine an aggregate risk level. We do not quantify the impact of any particular risk factor. Management’s assessment of the risk factors, as well as the trend in the quantitative allowance, supports management’s judgment for the overall required qualitative allowance. A smaller qualitative allowance may be required when our quantitative allowance has reflected incurred losses associated with the aggregate risk level. A greater qualitative allowance may be required if our quantitative allowance does not yet reflect the incurred losses associated with the aggregate risk level.

Our consideration of these factors has remained consistent for the quarter ended March 31, 2013. As discussed above, the improvements in the U.S. housing market, as well as internal and environmental risk factors, resulted in a $12 million decrease in the qualitative allowance from Dec. 31, 2012 to March 31, 2013.

To the extent actual results differ from forecasts or management’s judgment, the allowance for credit losses may be greater or less than future charge-offs.

Based on an evaluation of the allowance for credit losses as discussed in “Critical accounting estimates” on pages 34 and 35 in our 2012 Annual Report, we have allocated our allowance for credit losses as follows:

Allocation of allowance	March 31, 2013		Dec. 31, 2012		March 31, 2012
Commercial	27	%	27	%	20	%
Other residential mortgages	23		23		33
Foreign	13		12		10
Lease financing	11		13		12
Financial institutions	9		9		11
Commercial real estate	9		8		7
Wealth management (a)	8		8		7
Total	100	%	100	%	100	%

(a) Includes the allowance for wealth management mortgages.

The allocation of the allowance for credit losses is inherently judgmental, and the entire allowance for credit losses is available to absorb credit losses regardless of the nature of the loss.

The credit rating assigned to each credit is a significant variable in determining the allowance. If such credit were rated one grade better, the allowance would have decreased by $53 million, while if each credit were rated one grade worse, the allowance would have increased by $85 million. Similarly, if the loss given default were one rating worse, the allowance would have increased by $52 million, while if the loss given default were one rating better, the allowance would have decreased by $39 million. For impaired credits, if the net carrying value of the loans was 10% higher or lower, the allowance would have decreased or increased by $1 million, respectively.

Total allowance for credit losses/nonperforming assets	153.0		%	155.4		%

(a) Loans of consolidated investment management funds are not part of BNY Mellon’s loan portfolio. Included in these loans are nonperforming loans of $161 million at March 31, 2013 and $174 million at Dec. 31, 2012. These loans are recorded at fair value and therefore do not impact the provision for credit losses and allowance for loan losses, and accordingly are excluded from the nonperforming assets table above.

Nonperforming assets activity (in millions)	March 31, 2013			Dec. 31, 2012
Balance at beginning of period	$	249		$	274
Additions	12			12

Nonperforming assets were $234 million at March 31, 2013, a decrease of $15 million compared with $249 million at Dec. 31, 2012. The decrease primarily resulted from activity in the other residential mortgage loan portfolio consisting of the

return to accrual status of $11 million, sales of $6 million and charge-offs of $3 million, partially offset by additions of $12 million. Additionally, there were $3 million of repayments in the commercial loan portfolio.

See Note 5 of the Notes to Consolidated Financial Statements for additional information on our past due loans. See “Nonperforming assets” in Note 1 of the Notes to Consolidated Financial Statements in our 2012 Annual Report for our policy for placing loans on nonaccrual status.

Deposits

Total deposits were $239.7 billion at March 31, 2013, a decrease of 3% compared with $246.1 billion at Dec. 31, 2012. The decrease in deposits reflects lower levels of non-interest bearing deposits resulting from lower client deposits in our Investment Services business.

Noninterest-bearing deposits were $80.9 billion at March 31, 2013 compared with $93.0 billion at Dec. 31, 2012. Interest-bearing deposits were $158.8 billion at March 31, 2013 compared with $153.1 billion at Dec. 31, 2012.

Short-term borrowings

We fund ourselves primarily through deposits and, to a lesser extent, other borrowings, which are comprised of federal funds purchased and securities sold under repurchase agreements, payables to customers and broker-dealers, commercial paper, other borrowed funds and long-term debt. Certain other borrowings, for example, securities sold under repurchase agreements, require the delivery of securities as collateral.

See “Liquidity and dividends” below for a discussion of long-term debt and liquidity metrics that we monitor.

Information related to federal funds purchased and securities sold under repurchase agreements is presented below.

Average commercial paper outstanding was $245 million in the first quarter of 2013, $805 million in the fourth quarter of 2012 and $67 million in the first quarter of 2012. The maximum daily balance in the first quarter of 2013 was $1.4 billion compared with $2.4 billion in the fourth quarter of 2012 and $1.1 billion in the first quarter of 2012. Fluctuations between periods were a result of Parent funding requirements. Our commercial paper matures within 397 days from date of issue and is not redeemable prior to maturity or subject to voluntary prepayment.

Other borrowed funds primarily include borrowings under lines of credit by our Pershing subsidiaries and overdrafts of sub-custodian account balances in our Investment Services businesses. Overdrafts in

BNY Mellon 36

these accounts typically relate to timing differences for settlements. Other borrowed funds were $789 million at March 31, 2013 compared with $1.4 billion at Dec. 31, 2012 and $2.1 billion at March 31, 2012. Other borrowed funds averaged $1.2 billion in the first quarter of 2013, $1.1 billion in the fourth quarter of 2012 and $2.5 billion in the first quarter of 2012. The maximum daily balance in the first quarter of 2013 was $2.5 billion compared with $2.1 billion in the fourth quarter of 2012 and $5.5 billion in the first quarter of 2012. The decreases compared with the first quarter of 2012 reflect a change in the source of funding for our Pershing subsidiaries.

BNY Mellon defines liquidity as the ability of the Parent and its subsidiaries to access funding or convert assets to cash quickly and efficiently, especially during periods of market stress. Liquidity risk is the risk that BNY Mellon cannot meet its cash and collateral obligations at a reasonable cost for both expected and unexpected cash flows, without adversely affecting daily operations or financial conditions. Liquidity risk can arise from cash flow mismatches, market constraints from inability to convert assets to cash, inability to raise cash in the markets, deposit run-off, or contingent liquidity events.

For additional information on our liquidity policy, see “Risk Management - Liquidity risk” in our 2012 Annual Report.

Our overall approach to liquidity management is to ensure that sources of liquidity are sufficient in amount and diversity such that changes in funding requirements at the Parent and at the various bank subsidiaries can be accommodated routinely without material adverse impact on earnings, daily operations or our financial condition.

BNY Mellon seeks to maintain an adequate liquidity cushion in both normal and stressed environments and seeks to diversify funding sources by line of business, customer and market segment. Additionally, we seek to maintain liquidity ratios within approved limits and liquidity risk tolerance, maintain a liquid asset buffer that can be liquidated, financed and/or pledged as necessary, and control the levels and sources of wholesale funds.

Potential uses of liquidity include withdrawals of customer deposits and client drawdowns on unfunded credit or liquidity facilities. We actively monitor unfunded lending-related commitments, thereby reducing unanticipated funding requirements.

When monitoring liquidity, we evaluate multiple metrics to ensure ample liquidity for expected and unexpected events. Metrics include cashflow mismatches, asset maturities, access to debt and money markets, debt spreads, peer ratios, liquid assets, unencumbered collateral, funding sources and balance sheet liquidity ratios. We monitor the Basel III liquidity coverage ratio as applied to us, based on our current interpretation of Basel III. Ratios we currently monitor as part of our standard analysis include total loans as a percentage of total deposits, deposits as a percentage of total interest-earning assets, foreign deposits as a percentage of total interest-earnings assets, purchased funds as a percentage of total interest-earning assets, liquid assets as a percentage of total interest-earning assets, liquid assets as a percentage of purchased funds, and discount window collateral and central bank deposits as a percentage of total deposits. All of these ratios exceeded our minimum guidelines at March 31, 2013.

We also perform liquidity stress tests to ensure the Company maintains sufficient liquidity resources under multiple stress scenarios. Stress tests are based on scenarios that measure liquidity risks under unlikely but plausible events. The Company performs these tests under various time horizons ranging from one day to one year in a base case, as well as supplemental tests to determine whether the Company’s liquidity is sufficient for severe market events and firm-specific events. Under our scenario testing program, the results of the tests indicate that the Company has sufficient liquidity.

We define available funds as liquid funds (which include interest-bearing deposits with banks and federal funds sold and securities purchased under resale agreements), cash and due from banks, and interest-bearing deposits with the Federal Reserve and other central banks. The table below presents our total available funds including liquid funds at period-end and on an average basis. The lower level of available funds at March 31, 2013 compared with Dec. 31, 2012 resulted from a lower level of client deposits and by the redeployment of funds on our

37 BNY Mellon

balance sheet from interest-bearing deposits with the Federal Reserve and other central banks as we

increased the level of our investment securities and our loan portfolio.

On an average basis for the first quarter of 2013 and the first quarter of 2012, non-core sources of funds such as money market rate accounts, certificates of deposit greater than $100,000, federal funds purchased, trading liabilities and other borrowings were $21.9 billion and $16.8 billion, respectively. The increase primarily reflects higher levels of money market rate accounts. Average foreign deposits, primarily from our European-based Investment Services business, were $99.0 billion in the first quarter of 2013 compared with $86.7 billion in the first quarter of 2012. The increase primarily reflects growth in client deposits. Domestic savings and time deposits averaged $39.9 billion in the first quarter of 2013 compared with $34.3 billion in the first quarter of 2012. The increase primarily reflects higher time deposits. Deposit volumes could be impacted by proposed money market fund reform.

Average payables to customers and broker-dealers were $9.0 billion in the first quarter of 2013 and $7.6 billion in the first quarter of 2012. Payables to customers and broker-dealers are driven by customer trading activity and market volatility. Long-term debt averaged $18.9 billion in the first quarter of 2013 and $20.5 billion in the first quarter of 2012. The decrease in average long-term debt was driven by planned capital actions and anticipated maturities. Average noninterest-bearing deposits increased to $70.3 billion in the first quarter of 2013 from $66.6 billion in the first quarter of 2012 reflecting growth in client deposits. A significant reduction in our Investment Services business would reduce our access to deposits.

The Parent has four major sources of liquidity:

• cash on hand;

• dividends from its subsidiaries;

• access to the commercial paper market; and

• access to the long-term debt and equity markets.

Subsequent to March 31, 2013, our bank subsidiaries could declare dividends to the Parent of approximately $2.0 billion, without the need for a regulatory waiver. In addition, at March 31, 2013, non-bank subsidiaries of the Parent had liquid assets of approximately $1.4 billion.

In the first quarter of 2013, BNY Mellon paid a quarterly cash dividend of $0.13 per common share. In April 2013, BNY Mellon announced a 15% increase in the quarterly common stock dividend, from $0.13 to $0.15 per share beginning in the second quarter of 2013. The Federal Reserve’s current guidance provides that, for large bank holding companies like us, dividend payout ratios exceeding 30% of after-tax net income will receive particularly close scrutiny.

Restrictions on our ability to obtain funds from our subsidiaries are discussed in more detail in “Supervision and Regulation - Capital Planning - Payment of Dividends, Stock Repurchases and Other Capital Distributions” and in Note 20 of the Notes to Consolidated Financial Statements, both contained in our 2012 Annual Report.

The Parent’s average commercial paper borrowings were $245 million in the first quarter of 2013 compared with $67 million in the first quarter of

BNY Mellon 38

2012. The Parent had cash of $5.7 billion at March 31, 2013, compared with $4.0 billion at Dec. 31, 2012. In addition to issuing commercial paper for funding purposes, the Parent issues commercial paper, on an overnight basis, to certain custody clients with excess demand deposit balances. Overnight commercial paper outstanding issued by the Parent was $78 million at March 31, 2013 and $338 million at Dec. 31, 2012. Net of commercial paper outstanding, the Parent’s cash position at March 31, 2013, increased by $2.0 billion compared with Dec. 31, 2012, primarily reflecting the issuance of senior debt.

The Parent’s major uses of funds are payment of dividends, repurchases of common stock, principal and interest payments on its borrowings, acquisitions and additional investments in its subsidiaries.

In the first quarter of 2013, we repurchased 7.8 million common shares in the open market, at an average price of $27.21 per share, for a total of $211 million.

The Parent’s liquidity policy is to have sufficient cash on hand to meet its obligations over the next 18 to 24 months without the need to receive dividends from its bank subsidiaries or issue debt. As of March 31, 2013, the Parent was in compliance with its liquidity policy.

In addition to our other funding sources, we also have the ability to access the capital markets. In June 2010, we filed shelf registration statements on Form S-3 with the SEC covering the issuance of certain securities, including an unlimited amount of debt, common stock, preferred stock and trust preferred securities, as well as common stock issued under the Direct Stock Purchase and Dividend Reinvestment Plans. These registration statements will expire in June 2013, at which time we plan to file new shelf registration statements.

Our ability to access the capital markets on favorable terms, or at all, is partially dependent on our credit ratings, which, as of March 31, 2013, were as follows:

Credit ratings at March 31, 2013
	Moody’s	S&P	Fitch		DBRS
Parent:
Long-term senior debt	Aa3	A+	AA-		AA (low)
Subordinated debt	A1	A	A+		A (high)
Trust-preferred securities	A2	BBB	BBB+		A (high)
Short-term debt	P1	A-1	F1+		R-1 (middle)

(a) Represents senior debt issuer default rating.

As a result of Moody’s and S&P’s government support assumptions on U.S. financial institutions, the Parent’s Moody’s and S&P ratings benefit from one notch of “lift”.  Similarly, The Bank of New York Mellon’s and BNY Mellon, N.A.’s ratings benefit from two notches of “lift” from Moody’s and one notch of “lift” from S&P.

Long-term debt increased to $19.9 billion at March 31, 2013 from $18.5 billion at Dec. 31, 2012. In the first quarter of 2013, the Parent issued $1.5 billion of senior debt in anticipation of $1.6 billion of the Parent’s long-term debt that will mature in the remainder of 2013. Additionally, the Parent called $43 million of subordinated debt, and has the option to call $64 million of subordinated debt in the remainder of 2013, which it may call and refinance if market conditions are favorable.

The following table presents the long-term debt issued by the Parent in the first quarter of 2013.

At March 31, 2013, we had $603 million of trust preferred securities outstanding that qualify as Tier 1 capital, including $300 million that are currently callable. Any decision to take action with respect to the remaining trust preferred securities will be based on several considerations including interest rates, the availability of cash and capital, as well as the implementation of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act” or “Dodd-Frank”).

The double leverage ratio is the ratio of investment in subsidiaries divided by our consolidated equity, which included our noncumulative perpetual preferred stock plus trust preferred securities. Our double leverage ratio was 110.1% at March 31, 2013 and 109.9% at Dec. 31, 2012. The slight increase in the ratio primarily reflects a decline in the Company’s consolidated equity. The double leverage ratio is monitored by regulators and rating agencies and is an important constraint on our ability to invest in our subsidiaries and expand our businesses.

Pershing LLC, an indirect subsidiary of BNY Mellon, has committed and uncommitted lines of credit in place for liquidity purposes which are guaranteed by the Parent. The committed line of credit of $750 million extended by 17 financial institutions matured in March 2013. There were no borrowings against this line in the first quarter of 2013. In March 2013, we executed a new committed line of credit of $750 million extended by 16 financial institutions that matures in March 2014. Pershing LLC has nine separate uncommitted lines of credit amounting to $1.6 billion in aggregate. Average daily borrowing under these lines was $10 million, in aggregate, in the first quarter of 2013. See “Liquidity and dividends” in our 2012 Annual Report for a description of the convenants required to be maintained by the Parent for the committed lines of credit maintained by Pershing LLC. We are currently in compliance with these covenants.

Pershing Limited, an indirect UK-based subsidiary of BNY Mellon, has uncommitted lines of credit in place for liquidity purposes, which are guaranteed by the Parent. Pershing Limited has two separate uncommitted lines of credit amounting to $250 million in aggregate. Average daily borrowing under these lines was $81 million, in aggregate, in the first quarter of 2013.

Statement of cash flows

Cash used for operating activities was $2.7 billion for the three months ended March 31, 2013 compared with cash provided by operating activities of $114 million for the three months ended March 31, 2012. In the first three months of 2013, cash flows from operations were principally the result of changes in trading activities and the net loss in the first quarter of 2013. In the first three months of 2012, cash flows from operations were principally the result of earnings and changes in trading activities, primarily offset by changes in accruals and other balances.

In the three months ended March 31, 2013, cash provided by investing activities was $7.3 billion compared with $24.4 billion in the three months ended March 31, 2012. In the first three months of both 2013 and 2012, decreases in interest-bearing deposits with the Federal Reserve and other central banks, interest-bearing deposits with banks, as well as sales, paydowns and maturities of securities, partially offset by purchases of securities, were significant sources of funds.

In the three months ended March 31, 2013, cash used for financing activities was $4.8 billion compared with $24.4 billion for the three months ended March 31, 2012. In the first three months of both 2013 and 2012, a decrease in deposits, partially offset by an increase in federal funds purchased and securities sold under repurchase agreements and proceeds from the issuance of long-term debt were significant uses of funds.

Total The Bank of New York Mellon Corporation shareholders’ equity decreased compared with Dec. 31, 2012. The decrease primarily reflects the net loss recorded in the first quarter of 2013, share repurchases and a slight decrease in the value of our investment securities portfolio.

During the first quarter of 2013, we repurchased 9.2 million common shares for a total of $252 million.

In the first quarter of 2013, we generated $193 million of capital through the exercise of stock options and awards and employee benefit plan contributions.

From April 1, 2013 through May 8, 2013, we repurchased 11.0 million common shares in the open market, at an average price of $27.64 per common share for a total of $304 million.

In March 2013, BNY Mellon received confirmation that the Federal Reserve did not object to our 2013 comprehensive capital plan. The board of directors subsequently approved the repurchase of up to $1.35 billion worth of common shares, or up to approximately $335 million per quarter in 2013, including both open market purchases and employee benefit plan repurchases. The board-authorized share repurchase amount increased 16% from the prior year’s authorization. The board also approved a 15% increase in the quarterly common stock

dividend to $0.15 per share beginning in the second quarter of 2013.

The unrealized net of tax gain on our available-for-sale investment securities portfolio recorded in accumulated other comprehensive income was $1.2 billion at March 31, 2013 compared with $1.3 billion at Dec. 31, 2012. The decrease in the valuation of the investment securities portfolio was driven by an increase in market interest rates and $48 million of net realized securities gains in the first quarter of 2013.

Capital adequacy

Regulators establish certain levels of capital for bank holding companies and banks, including BNY Mellon and our bank subsidiaries, in accordance with established quantitative measurements. For the Parent to maintain its status as a financial holding company, our bank subsidiaries and BNY Mellon must, among other things, qualify as “well capitalized”.

As of March 31, 2013 and Dec. 31, 2012, BNY Mellon and our bank subsidiaries were considered “well capitalized” on the basis of the Basel I Total and Tier 1 capital to risk-weighted assets ratios and the leverage ratio (Basel I Tier 1 capital to quarterly average assets as defined for regulatory purposes).

41 BNY Mellon

Our consolidated and largest bank subsidiary, The Bank of New York Mellon, capital ratios are shown below.

Consolidated and largest bank subsidiary capital ratios	Well capitalized		Adequately capitalized			March 31,		Dec. 31,		March 31,

Leverage	5	%	3%-4%		(d)	5.2	%	5.4	%	5.7	%

(a) The Federal Reserve’s Notices of Proposed Rulemaking (“NPRs”) require the Tier 1 common equity ratio to be the lower of the ratio as calculated under the Standardized Approach or Advanced Approach. At March 31, 2013, this ratio was 9.4% under the Standardized Approach compared with 9.7% under the Advanced Approach. At Dec. 31, 2012, this ratio was higher under the Standardized Approach, and therefore was presented under the Advanced Approach. The estimated Basel III Tier 1 common equity ratio of 7.6% at March 31, 2012 was based on prior Basel III guidance and the proposed market risk rule.

(b) See “Supplemental Information - Explanation of Non-GAAP financial measures” beginning on page 48 for a calculation of this ratio.

(c) When in this Form 10-Q we refer to BNY Mellon’s or our bank subsidiary’s “Basel I” capital measures (e.g., Basel I Total capital or Basel I Tier 1 capital), we mean Total or Tier 1 capital, as applicable, as calculated under the Federal Reserve’s risk-based capital guidelines that are based on the 1988 Basel Accord, which is often referred to as “Basel I”. Includes full capital credit for certain capital instruments outstanding at March 31, 2013, because implementing regulations with respect to the Collins amendment to the Dodd-Frank Act have not been adopted.

(d) The minimum leverage ratio for state member banks is 3% or 4%, depending on factors specified in regulations.

N/A - Not applicable at the consolidated company level. Well capitalized and adequately capitalized have not been defined for Basel III.

Our estimated Basel III Tier 1 common equity ratio

was 9.4% at March 31, 2013 compared with 9.8% at Dec. 31, 2012. The decrease primarily resulted from the net loss recorded in the first quarter of 2013.

At March 31, 2013, the amounts of capital by which BNY Mellon and our largest bank subsidiary, The Bank of New York Mellon, exceed the “well capitalized” guidelines are as follows.

Capital above guidelines at March 31, 2013 (in millions)	Consolidated		The Bank of New York Mellon
Tier 1 capital	$	9,056	$	6,951
Total capital	5,565		3,543
Leverage	545		507

Failure to satisfy regulatory standards, including “well capitalized” status or capital adequacy guidelines more generally, could result in limitations on our activities and adversely affect our financial condition. See the discussion of these matters in our 2012 Annual Report in “Supervision and Regulation-Regulated Entities of BNY Mellon” and “Risk Factors-Operational and Business Risk-

Failure to satisfy regulatory standards, including “well capitalized” and “well managed” status or capital adequacy guidelines more generally, could result in limitations on our activities and adversely affect our business and financial condition.”

Capital ratios vary depending on the size of the balance sheet at quarter-end and the level and types of investments. The balance sheet size fluctuates from quarter to quarter based on levels of customer and market activity. In general, when servicing clients are more actively trading securities, deposit balances and the balance sheet as a whole are higher. In addition, when markets experience significant volatility or stress, our balance sheet size may increase considerably as client deposit levels increase.

In the first quarter of 2013, net Basel I Tier 1 common equity decreased $455 million, primarily driven by the net loss recorded in the first quarter of 2013 and share repurchases.

Our Basel I Tier 1 capital ratio was 13.6% at March 31, 2013 compared with 15.0% at Dec. 31, 2012. The decrease in the Basel I Tier 1 capital ratio primarily reflects the net loss recorded in the first quarter of 2013, as well as higher risk-weighted assets driven by the required implementation of the Basel II.5 - final market risk rule and a change in asset mix.

In the first quarter of 2013, BNY Mellon was required to implement the Basel II.5 - final market risk rule. Implementation of these rules resulted in an approximately 35-40 basis points decrease to the consolidated Basel I Tier 1 common equity to risk-weighted assets ratio, the consolidated Basel I Tier 1 capital ratio and the consolidated Basel I Total capital ratio. Additionally, these amended market risk rules require us to make publicly available certain quantitative and other disclosures at least quarterly, commencing with the quarterly period ended March 31, 2013. These disclosures will be posted on our website as described below under “Website information.”

Our Basel I Tier 1 leverage ratio was 5.2% at March 31, 2013 compared with 5.3% at Dec. 31, 2012. The leverage ratio of The Bank of New York Mellon was 5.2% at March 31, 2013 compared with

5.4% at Dec. 31, 2012. The decreases in both of the leverage ratios primarily resulted from the net loss recorded in the first quarter of 2013.

The Tier 1 capital, total capital and leverage capital ratios for The Bank of New York Mellon decreased at March 31, 2013 compared with Dec. 31, 2012. The decreases in these ratios primarily reflect the net loss recorded in the first quarter of 2013. Higher risk-weighted assets driven by the required implementation of the Basel II.5 - final market risk rule and a change in asset mix also contributed to the decrease in the Tier 1 and total capital ratios.

The following table shows the impact of a $1 billion increase or decrease in risk-weighted assets/quarterly average assets or a $100 million increase or decrease in common equity on the consolidated capital ratios at March 31, 2013.

Our tangible BNY Mellon shareholders’ equity to tangible assets of operations ratio was 5.9% at March 31, 2013 compared with 6.4% at Dec. 31, 2012. The decrease in the ratio was driven by the net loss recorded in the first quarter of 2013.

At March 31, 2013, we had $603 million of trust preferred securities outstanding that qualify as Tier 1 capital, including $300 million that are currently callable. Any decision to take action with respect to the remaining trust preferred securities will be based on several considerations including interest rates, the availability of cash and capital, as well as the implementation of the Dodd-Frank Act.

Trading activities and risk management

Our trading activities are focused on acting as a market maker for our customers and facilitating customer trades. Positions managed for our own account are immaterial to our foreign exchange and other trading revenue and to our overall results of operations. The risk from market-making activities for customers is managed by our traders and limited in total exposure through a system of position limits, a value-at-risk (“VaR”) methodology based on a Monte Carlo simulation, stop loss advisory triggers, and other market sensitivity measures. The calculation of our VaR used by management and presented below, assumes a one-day holding period, utilizes a 99% confidence level, and incorporates the non-linear characteristics of options. See Note 17 of the Notes to Consolidated Financial Statements for additional information on the VaR methodology.

The following tables indicate the calculated VaR amounts for the trading portfolio for the designated periods:

VaR(a)	1st Quarter 2013							March 31, 2013

(a) VaR figures do not reflect the impact of CVA guidance in ASC 820. This is consistent with the regulatory treatment. VaR exposure does not include the impact of the Company’s consolidated investment management funds and seed capital investments.

N/M - Because the minimum and maximum may occur on different days for different risk components, it is not meaningful to compute a portfolio diversification effect.

The interest rate component of VaR represents instruments whose values predominantly vary with the level or volatility of interest rates. These instruments include, but are not limited to: debt securities, mortgage-backed securities, swaps, swaptions, forward rate agreements, exchange traded futures and options, and other interest rate derivative products.

The foreign exchange component of VaR represents instruments whose values predominantly vary with the level or volatility of currency exchange rates or interest rates. These instruments include, but are not limited to: currency balances, spot and forward transactions, currency options, and exchange traded futures and options, and other currency derivative products.

The equity component of VaR is comprised of instruments that represent an ownership interest in the form of domestic and foreign common stock or other equity-linked instruments. These instruments include, but are not limited to: common stock, exchange traded funds, American Depositary Receipts, listed equity options (puts and calls), OTC equity options, equity total return swaps, equity index futures and other equity derivative products.

The diversification component of VaR is the risk reduction benefit that occurs when combining portfolios and offsetting positions, and from the correlated behavior of risk factor movements.

During the first quarter of 2013, interest rate risk generated 80% of average VaR, equity risk generated 13% of average VaR and foreign exchange risk accounted for 7% of average VaR. During the first quarter of 2013, our daily trading loss did not exceed

our calculated VaR amount of the overall portfolio on any given day.

The following table of total daily trading revenue or loss illustrates the number of trading days in which our trading revenue or loss fell within particular ranges during the past five quarters.

Foreign exchange and other trading

Foreign exchange and other trading revenue totaled $161 million in the first quarter of 2013, $191 million in the first quarter of 2012 and $139 million in the fourth quarter of 2012. In the first quarter of 2013, foreign exchange revenue totaled $149 million, an increase of 10% year-over-year and 41% (unannualized) sequentially. The year-over-year increase primarily reflects higher volumes, partially offset by a decrease in volatility, while the sequential increase reflects increased volatility and higher volumes. Additionally, foreign exchange revenue continues to be impacted by increasingly competitive market pressures. Other trading revenue totaled $12 million in the first quarter of 2013, compared with $55 millionfirst quarter of 2012 and $33 million in the fourth quarter of 2012. Both decreases were principally due to losses on interest rate hedges and lower fixed income and equity trading. Foreign exchange revenue and fixed income trading revenue is reported in the Investment Services business and the Other segment. Equity/other trading revenue is primarily reported in the Other segment.

Trading assets include debt and equity instruments and derivative assets, primarily interest rate and foreign exchange contracts, not designated as hedging instruments. Trading assets totaled $12.2 billion at March 31, 2013 compared with $9.4

45 BNY Mellon

billion at Dec. 31, 2012. The increase in trading assets resulted from higher levels of securities inventory, principally U.S. Government, agency mortgage-backed and U.S. equities, as we expand our broker-dealer business.

Trading liabilities include debt and equity instruments, and derivative liabilities, primarily interest rate and foreign exchange contracts, not designated as hedging instruments. Trading liabilities totaled $8.8 billion at March 31, 2013 compared with $8.2 billion at Dec. 31, 2012.

Under our mark-to-market methodology for derivative contracts, an initial “risk-neutral” valuation is performed on each position assuming time-discounting based on a AA credit curve. In addition, we consider credit risk in arriving at the fair value of our derivatives.

As required by ASC 820 - Fair Value Measurements and Disclosures, we reflect external credit ratings as well as observable credit default swap spreads for both ourselves as well as our counterparties when measuring the fair value of our derivative positions. Accordingly, the valuation of our derivative positions is sensitive to the current changes in our own credit spreads, as well as those of our counterparties. In addition, in cases where a counterparty is deemed impaired, further analyses are performed to value such positions.

At March 31, 2013, our over-the-counter (“OTC”) derivative assets of $5.3 billion included a credit valuation adjustment (“CVA”) deduction of $60 million. Our OTC derivative liabilities of $6.5 billion included a debit valuation adjustment (“DVA”) of $10 million related to our own credit spread. Net of hedges, the CVA decreased $31 million and the DVA decreased $13 million in the first quarter of 2013. The net impact of these adjustments increased foreign exchange and other trading revenue by $18 million in the first quarter of 2013.

In the fourth quarter of 2012, net of hedges, the CVA decreased $34 million and the DVA decreased $6 million. The net impact of these adjustments increased foreign exchange and other trading revenue by $28 million in the fourth quarter of 2012.

In the first quarter of 2012, net of hedges, the CVA decreased $16 million and the DVA decreased $5

million. The net impact of these adjustments increased foreign exchange and other trading revenue by $11 million in the first quarter of 2012.

The table below summarizes the risk ratings for our foreign exchange and interest rate derivative counterparty credit exposure. This information indicates the degree of risk to which we are exposed and significant changes in ratings classifications for which our foreign exchange and other trading activity could result in increased risk for us. The year-over-year increase in the percentage of exposure to counterparties with a risk rating profile of A+ to A- reflects a general increase in foreign exchange activity within this ratings category as well as increases in existing exposure to our inter-bank counterparties.

Asset/liability management

Our diversified business activities include processing securities, accepting deposits, investing in securities, lending, raising money as needed to fund assets, and other transactions. The market risks from these activities are interest rate risk and foreign exchange risk. Our primary market risk is exposure to movements in U.S. dollar interest rates and certain foreign currency interest rates. We actively manage interest rate sensitivity and use earnings simulation and discounted cash flow models to identify interest rate exposures.

An earnings simulation model is the primary tool used to assess changes in pre-tax net interest revenue. The model incorporates management’s assumptions regarding interest rates, balance changes on core deposits, market spreads, changes in

BNY Mellon 46

the prepayment behavior of loans and securities and the impact of derivative financial instruments used for interest rate risk management purposes. These assumptions have been developed through a combination of historical analysis and future expected pricing behavior and are inherently uncertain. As a result, the earnings simulation model cannot precisely estimate net interest revenue or the impact of higher or lower interest rates on net interest revenue. Actual results may differ from projected results due to timing, magnitude and frequency of interest rate changes, and changes in market conditions and management’s strategies, among other factors.

These scenarios do not reflect strategies that management could employ to limit the impact as interest rate expectations change. The table below relies on certain critical assumptions regarding the balance sheet and depositors’ behavior related to interest rate fluctuations and the prepayment and extension risk in certain of our assets. To the extent that actual behavior is different from that assumed in the models, there could be a change in interest rate sensitivity.

We evaluate the effect on earnings by running various interest rate ramp scenarios from a baseline scenario. These scenarios are reviewed to examine the impact of large interest rate movements. Interest rate sensitivity is quantified by calculating the change in pre-tax net interest revenue between the scenarios over a 12-month measurement period.

The following table shows net interest revenue sensitivity for BNY Mellon:

Estimated changes in net interest revenue at March 31, 2013 (dollar amounts in millions)
up 200 bps parallel rate shift vs. baseline (a)	$	351
up 100 bps parallel rate shift vs. baseline (a)	311
Long-term up 50 bps, short-term unchanged (b)	142
Long-term down 50 bps, short-term unchanged (b)	(114		)

(a) In the parallel rate shift, both short-term and long-term rates move equally.

(b) Long-term is equal to or greater than one year.

bps - basis points.

The 100 basis point ramp scenario assumes rates increase 25 basis points in each of the next four quarters and the 200 basis point ramp scenario assumes a 50 basis point per quarter increase.

Our net interest revenue sensitivity table above incorporates assumptions about the impact of changes in interest rates on depositor behavior based on historical experience. Given the exceptionally low interest rate environment, a rise in interest rates could lead to higher depositor withdrawals than historically experienced.

Growth or contraction of deposits could also be affected by the following factors:

• Global economic uncertainty, particularly in Europe;

• Our ratings relative to other financial institutions’ ratings; and

• Money market mutual fund reform.

Any of these events could change our assumptions about depositor behavior and have a significant impact on our balance sheet and net interest revenue.

Off-balance sheet arrangements

Off-balance sheet arrangements discussed in this section are limited to guarantees, retained or contingent interests, support agreements, and obligations arising out of unconsolidated variable interest entities. For BNY Mellon, these items include certain credit guarantees and securitizations. Guarantees include: lending-related guarantees issued as part of our corporate banking business, and securities lending indemnifications issued as part of our Investment Services business. See Note 18 of the Notes to Consolidated Financial Statements for a further discussion of our off-balance sheet arrangements.

Supplemental information - Explanation of Non-GAAP financial measures

BNY Mellon has included in this Form 10-Q certain Non-GAAP financial measures based upon Tier 1 common equity and tangible common shareholders’ equity. BNY Mellon believes that the ratio of Tier 1 common equity to risk-weighted assets and the ratio of tangible common shareholders’ equity to tangible assets of operations are measures of capital strength that provide additional useful information to investors, supplementing the Tier 1 and Total capital ratios which are utilized by regulatory authorities. The ratio of Basel I Tier 1 common equity to risk-weighted assets excludes preferred stock and trust preferred securities from the numerator of the ratio. Unlike the Basel I Tier 1 and Total capital ratios, the tangible common shareholders’ equity ratio fully incorporates those changes in investment securities valuations which are reflected in total shareholders’ equity. In addition, this ratio is expressed as a percentage of the actual book value of assets, as opposed to a percentage of a risk-based reduced value established in accordance with regulatory requirements, although BNY Mellon in its calculation has excluded certain assets which are given a zero percent risk-weighting for regulatory purposes. Further, BNY Mellon believes that the return on tangible common equity measure, which excludes goodwill and intangible assets net of deferred tax liabilities, is a useful additional measure for investors because it presents a measure of BNY Mellon’s performance in reference to those assets which are productive in generating income. BNY Mellon has provided a measure of tangible book value per share, which it believes provides additional useful information as to the level of such assets in relation to shares of common stock outstanding. BNY Mellon has presented its estimated Basel III Tier 1 common equity ratio on a basis that is representative of how it currently understands the Basel III rules. Management views the Basel III Tier 1 common equity ratio as a key measure in monitoring BNY Mellon’s capital position. Additionally, the presentation of the Basel III Tier 1 common equity ratio allows investors to compare BNY Mellon’s Basel III Tier 1 common equity ratio with estimates presented by other companies.

BNY Mellon has presented revenue measures which exclude the effect of noncontrolling interests related to consolidated investment management funds;

expense measures which exclude M&I expenses, litigation charges, restructuring charges and amortization of intangible assets; as well as earnings per share and the provision for income taxes which exclude the charge related to the disallowance of certain foreign tax credits; and investment management fees excluding the impact of the acquisition of Meriten. Return on equity measures and operating margin measures, which exclude some or all of these items, are also presented. BNY Mellon believes that these measures are useful to investors because they permit a focus on period-to-period comparisons which relate to the ability of BNY Mellon to enhance revenues and limit expenses in circumstances where such matters are within BNY Mellon’s control. The excluded items, in general, relate to certain ongoing charges as a result of prior transactions or where we have incurred charges. M&I expenses primarily relate to the acquisitions of Global Investment Servicing on July 1, 2010 and BHF Asset Servicing GmbH on Aug. 2, 2010. M&I expenses generally continue for approximately three years after the transaction and can vary on a year-to year basis depending on the stage of the integration. BNY Mellon believes that the exclusion of M&I expenses provides investors with a focus on BNY Mellon’s business as it would appear on a consolidated going-forward basis, after such M&I expenses have ceased. Future periods will not reflect such M&I expenses, and thus may be more easily compared to our current results if M&I expenses are excluded. Litigation charges represent accruals for loss contingencies that are both probable and reasonably estimable, but exclude standard business-related legal fees. Restructuring charges relate to our operational excellence initiatives and migrating positions to global delivery centers. Excluding these charges permits investors to view expenses on a basis consistent with how management views the business.

The presentation of income from consolidated investment management funds, net of net income attributable to noncontrolling interest related to the consolidation of certain investment management funds permits investors to view revenue on a basis consistent with how management views the business. BNY Mellon believes that these presentations, as a supplement to GAAP information, give investors a clearer picture of the results of its primary businesses.

BNY Mellon 48

In this Form 10-Q, the net interest margin is presented on an FTE basis. We believe that this presentation provides comparability of amounts arising from both taxable and tax-exempt sources, and is consistent with industry practice.

Each of these measures as described above is used by management to monitor financial performance, both on a company-wide and on a business-level basis.

(a) The Federal Reserve’s Notices of Proposed Rulemaking (“NPRs”) require the Tier 1 common equity ratio to be the lower of the ratio as calculated under the Standardized Approach or Advanced Approach. At March 31, 2013, this ratio was 9.4% under the Standardized Approach compared with 9.7% under the Advanced Approach. For all periods prepared under the NPRs prior to March 31, 2013, this ratio was higher under the Standardized Approach, and therefore was presented under the Advanced Approach. The estimated Basel III Tier 1 common equity ratio at March 31, 2012 was based on our interpretation of prior Basel III guidance and the proposed market risk rule.

(b) The NPRs and prior Basel III guidance do not add back to capital the adjustment to other comprehensive income that Basel I makes for pension liabilities and available-for-sale securities. Also, under the NPRs and prior Basel III guidance, pension assets recorded on the balance sheet and adjustments related to equity method investments are a deduction from capital.

(c) Primary differences between risk-weighted assets determined under Basel I compared with the NPRs and prior Basel III guidance include: the determination of credit risk under Basel I uses predetermined risk weights and asset classes and relies in part on the use of external credit ratings, while the NPRs use, in addition to the broader range of predetermined risk weights and asset classes, certain alternatives to external credit ratings. Securitization exposure receives a higher risk-weighting under the NPRs and prior Basel III guidance than Basel I; also, the NPRs and prior Basel III guidance includes additional adjustments for operational risk, market risk, counterparty credit risk and equity exposures.

Recent accounting and regulatory developments

Proposed Accounting Standards

Proposed ASU - Revenue from Contracts with Customers

In June 2010, the FASB issued a proposed ASU, “Revenue from Contracts with Customers”. This proposed ASU is the result of a joint project of the FASB and the IASB to clarify the principles for recognizing revenue and develop a common standard for U.S. GAAP and IFRS. This proposed ASU would establish a broad principle that would require an entity to identify the contract with a customer, identify the separate performance obligations in the contract, determine the transaction price, allocate the transaction price to the separate performance obligations and recognize revenue when each separate performance obligation is satisfied. In 2011, the FASB and the IASB revised several aspects of the original proposal to include distinguishing between goods and services, segmenting contracts, accounting for warranty obligations and deferring contract origination costs.

In November 2011, the FASB re-exposed the proposed ASU. A final standard is expected to be issued in 2013. A retrospective application transition method would be permitted, but the FASB and IASB provides a practicable expedient to reduce the burden on preparers. The FASB and IASB tentatively decided that the effective date of the proposed standard would be annual reporting periods beginning on or after Jan. 1, 2017.

Proposed ASU - Principal versus Agent Analysis

In November 2011, the FASB issued a proposed ASU “Principal versus Agent Analysis”. This proposed ASU would rescind the 2010 indefinite deferral of FAS 167 for certain investment funds, including mutual funds, hedge funds, mortgage real estate investment funds, private equity funds, and venture capital funds, and amends the pre-existing guidance for evaluating consolidation of voting general partnerships and similar entities. The proposed ASU also amends the criteria for determining whether an entity is a variable interest entity under FAS 167, which could affect whether an entity is within its scope. Accordingly, certain funds that previously were not consolidated must be

reviewed to determine whether they will now be required to be consolidated. The proposed accounting standard will continue to require BNY Mellon to determine whether or not it has a variable interest in a variable interest entity. However, consolidation of its variable interest entity and voting general partnership asset management funds will be based on whether or not BNY Mellon, as the asset manager, uses its power as a decision maker as either a principal or an agent. Based on a preliminary review of the proposed ASU, we do not expect to be required to consolidate additional mutual funds, hedge funds, mortgage real estate investment funds, private equity funds, and venture capital funds. In addition, we expect to de-consolidate a portion of the CLOs we currently consolidate, with further deconsolidation possible depending on future changes to BNY Mellon’s investment in subordinated notes. The FASB is currently evaluating comment letters received. A final ASU is expected to be issued during the second quarter of 2013.

FASB and IASB project on Leases

In August 2010, the FASB and IASB issued a joint proposed ASU, “Leases”. FASB has tentatively decided that lessees would apply a “right-of-use” accounting model. This would require the lessee to recognize both a right-of-use asset and a corresponding liability to make lease payments at the lease commencement date, both measured at the present value of the lease payments. The right-of-use asset would be amortized on a systematic basis that would reflect the pattern of consumption of the economic benefits of the leased asset. The liability to make lease payments would be subsequently de-recognized over time by applying the effective interest method to apportion the periodic payment to reductions in the liability to make lease payments and interest expense. Lessors would account for leases by applying a “receivable and residual” accounting approach for those leases where the lessee acquires and consumes more than an insignificant portion of the underlying asset over the lease term. The lessor would recognize a right to receive lease payments and a residual asset at the date of the commencement of the lease. The lessor would initially measure the right to receive lease payments at the sum of the present value of the lease payments, discounted using the rate the lessor charges the lessee. The lessor would initially measure the residual asset as an allocation of the

53 BNY Mellon

carrying amount of the underlying asset and would subsequently measure the residual asset by accreting it over the lease term, using the rate the lessor charges the lessee. The FASB is expected to re-expose the standard during 2013.

Proposed ASU - Financial Instruments - Credit Losses

In December 2012, the FASB issued a proposed ASU, “Financial Instruments-Credit Losses”. This proposed ASU would result in a single model to account for credit losses on financial assets. The proposal would remove the probable threshold for recognizing credit losses and require an estimate of the contractual cash flows an entity does not expect to collect on financial assets not measured at fair value through the income statement. The proposal would also change current practice for recognizing other-than-temporary impairment and interest income on debt securities. In addition, the proposal would result in the recognition of an allowance for credit losses for nearly all types of debt instruments. The proposal would expand the credit quality disclosures to require information about changes in the factors that influence estimates of credit losses and the reasons for those changes. Comments on this proposed ASU are due on May 31, 2013.

Proposed ASU - Effective Control for Transfers with Forward Agreements to Repurchase Assets and Accounting for Repurchase Financings

In January 2013, the FASB issued a proposed ASU, “Effective Control for Transfers with Forward Agreements to Repurchase Assets and Accounting for Repurchase Financings.” This proposed ASU would require certain repurchase agreements to be accounted for as secured borrowings. For repurchase agreements and similar transactions accounted for as secured borrowings, an entity would be required to disclose the carrying value of the borrowing disaggregated by the type of collateral pledged. Comments on this proposed ASU were due on March 29, 2013.

Proposed ASU - Recognition and Measurement of Financial Assets and Financial Liabilities

In February 2013, the FASB issued a proposed ASU, “Recognition and Measurement of Financial Assets and Financial Liabilities.” This proposed ASU would affect entities that hold financial assets and

liabilities and would change the methodology related to recognition, classification, measurement and presentation of financial instruments. The scope of the proposed ASU would exclude instruments classified in shareholder’s equity, share-based arrangements, pension plans, leases, guarantees and derivative instruments accounted under ASC 815. Financial assets would be classified and measured based on the instrument’s cash flow characteristics and an entity’s business model for managing the instrument. Financial liabilities would generally be measured initially at their transaction price. The proposal includes three principal classification and measurement categories: (1) fair value for which all changes in fair value are recognized in net income; (2) fair value with qualifying changes in fair value recognized in other comprehensive income; and (3) amortized cost. This proposed ASU requires financial assets and liabilities to be presented separately on the balance sheet by measurement category. In addition, the fair value of financial assets and liabilities accounted for under amortized cost would be presented parenthetically on the balance sheet. Comments on this proposed ASU are due on May 15, 2013.

Proposed ASU - Reporting Discontinued Operations

In April 2013, the FASB issued a proposed ASU, “Reporting Discontinued Operations.” This proposed ASU would change the criteria and enhance the reporting for discontinued operations. The proposal would also enhance disclosure requirements and adds new disclosures for individually material dispositions that do not qualify as discontinued operations. Under the proposal, a discontinued operation is a component of an entity, or group of components of an entity, that either has been disposed of, or is classified as held for sale and (1) is part of a single coordinated plan to dispose of a separate major line of business or separate major geographical area of operations, or (2) is a business that, on acquisition, meets the criteria for classification as held for sale. The proposal no longer precludes the presentation of a discontinued operation if there is significant continuing involvement with the component after the disposal or if there are ongoing operations or cash flows. Under the proposal, for disposals that are material but do not qualify as discontinued operations, disclosures of pre-tax income or losses of the disposed component and a reconciliation of the major classes of assets and liabilities held for sale to

BNY Mellon 54

the amounts presented separately on the balance sheet would be required. Comments on this proposed ASU are due on Aug. 30, 2013.

Adoption of new accounting standards

For a discussion of the adoption of new accounting standards, see Note 2 of the Notes to Consolidated Financial Statements.

IFRS

International Financial Reporting Standards (“IFRS”) are a set of standards and interpretations adopted by the International Accounting Standards Board. The SEC is currently considering a potential IFRS adoption process in the United States, which would, in the near term, provide domestic issuers with an alternative accounting method and ultimately could replace U.S. GAAP reporting requirements with IFRS reporting requirements. The intention of this adoption would be to provide the capital markets community with a single set of high-quality, globally accepted accounting standards. The adoption of IFRS for U.S. companies with global operations would allow for streamlined reporting, allow for easier access to foreign capital markets and investments, and facilitate cross-border acquisitions, ventures or spin-offs.

In November 2008, the SEC proposed a “roadmap” for phasing in mandatory IFRS filings by U.S. public companies. The roadmap is conditional on progress towards milestones that would demonstrate improvements in both the infrastructure of international standard setting and the preparation of the U.S. financial reporting community. In February 2010, the SEC issued a statement confirming their position that they continue to believe that a single set of high-quality, globally accepted accounting standards would benefit U.S. investors. The SEC continues to support the dual goals of improving financial reporting in the United States and reducing country-by-country disparities in financial reporting. The SEC is developing a work plan to aid in its evaluation of the impact of IFRS on the U.S. securities market.

In May 2011, the SEC published a staff paper, “Exploring a Possible Method of Incorporation”, that presents a possible framework for incorporating IFRS into the U.S. financial reporting system. In the staff paper, the SEC staff elaborates on an approach

that combines elements of convergence and endorsement. This approach would establish an endorsement protocol for the FASB to incorporate newly issued or amended IFRS into U.S. GAAP. During a transition period (e.g., five to seven years), differences between IFRS and U.S. GAAP would be potentially eliminated through ongoing FASB standard setting.

In July 2012, the SEC staff released its final report on IFRS. This Final Report will be used by the SEC Commissioners to decide whether and, if so, when and how to incorporate IFRS into the financial reporting system for U.S. companies. The staff has not specifically requested comments on the Final Report. It is not known when the SEC will make a final decision on the adoption of IFRS in the U.S.

While the SEC decides whether IFRS will be required to be used in the preparation of our consolidated financial statements, a number of countries have mandated the use of IFRS by BNY Mellon’s subsidiaries in their statutory reports. Such countries include Belgium, Brazil, the Netherlands, Australia, Hong Kong, Canada and South Korea.

Proposed Update to Internal Controls - Integrated Framework

In December 2011, The Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) issued for public comment a proposed update to Internal Control - Integrated Framework. The original Framework, issued in 1992, is used by most U.S. public companies and many others to evaluate and report on the effectiveness of their internal control over external financial reporting.

Since the original Framework was introduced, business has become increasingly global and complex. Regulatory regimes also have expanded, and additional forms of external reporting are emerging. The COSO Board has updated the original Framework to make it more relevant to investors and other stakeholders.

The more significant proposed changes to the original Framework include: applying a principles-based approach, clarifying the role of objective-setting in internal control, reflecting the increased relevance of technology, enhancing governance concepts, expanding the objectives of financial reporting, enhancing consideration of anti-fraud

55 BNY Mellon

expectations, and considering different business models and organizational structures.

In September 2012, COSO released a draft of its Internal Control Over External Financial Reporting (“ICEFR”): Compendium of Approaches and Examples (“the Compendium”). The Compendium provides guidance on applying COSO’s Internal Control -Integrated Framework to external financial reporting. COSO also released a revised version of its Internal Control -Integrated Framework (“ICIF”) that incorporates changes based on comments received. Comments on the Compendium and the revised ICIF were due on Nov. 20, 2012. The final document is expected to be issued in May 2013.

Regulatory developments

Resolution Planning

As required by the Dodd-Frank Act, the Federal Reserve and FDIC jointly issued a final rule requiring certain organizations, including each BHC with consolidated assets of $50 billion or more, to report periodically to regulators a resolution plan for its rapid and orderly resolution in the event of material financial distress or failure. In addition, the FDIC issued a final rule that requires insured depository institutions with $50 billion or more in total assets, such as The Bank of New York Mellon, to submit to the FDIC periodic plans for resolution in the event of the institution’s failure.

The two resolution plan rules are complementary and we submitted our initial resolution plan in conformity with both rules on Oct. 1, 2012. The public portions of our resolution plan are available on the FDIC’s website. We are required to submit updated resolution plans annually.  Pursuant to recent guidance issued by the Federal Reserve and FDIC to all companies that submitted initial resolution plans in 2012, the submission date for our 2013 plan has been extended to Oct. 1, 2013.

For a summary of regulatory matters relevant to our operations, see “Supervision and regulation” in our 2012 Annual Report. 

Government monetary policies and competition

Government monetary policies

The Federal Reserve Board has the primary responsibility for U.S. monetary policy. Its actions have an important influence on the demand for credit and investments and the level of interest rates, and thus on the earnings of BNY Mellon.

Competition

BNY Mellon is subject to intense competition in all aspects and areas of our business. Our Investment Management business competes with asset management firms, hedge funds, investment banking companies, and other financial services companies, including trust banks, brokerage firms, and insurance companies. We may compete with these firms and companies domestically or internationally. Our Investment Services business competes with domestic and foreign financial services firms that offer custody services, corporate trust services, clearing services, collateral services, credit services, securities brokerage, foreign exchange services, derivatives services, depositary receipt services, transfer agent services and cash management services and related products, as well as a wide range of technology service providers, such as financial service data processing firms. Competition is based on a number of factors including, among others, customer service, quality and range of products and services offered, price, reputation, interest rates, lending limits and customer convenience.

Many of our competitors, with the particular exception of bank and financial holding companies, banks and trust companies, are not subject to regulation as extensive as BNY Mellon, and, as a result, may have a competitive advantage over us and our subsidiaries in certain respects.

In recent years, there has been substantial consolidation among companies in the financial services industry. Many broad-based financial services firms now have the ability to offer a wide range of products, from loans, deposit-taking and insurance to brokerage and asset management, which may enhance their competitive position.

BNY Mellon 56

As part of our business strategy, we seek to distinguish ourselves from competitors by the level of service we deliver to our clients. We also believe that technological innovation is an important competitive factor, and, for this reason, have made and continue to make substantial investments in this area. The ability to recover quickly from unexpected events is a competitive factor, and we have devoted significant resources to being able to implement this. For additional discussion regarding competition, see “Risk Factors - Operational and Business Risk - We are subject to intense competition in all aspects of our business, which could negatively affect our ability to maintain or increase our profitability” in our 2012 Annual Report.

Notes to Consolidated Financial Statements

Note 1 - Basis of presentation

Basis of Presentation

The accounting and financial reporting policies of BNY Mellon, a global financial services company, conform to U.S. generally accepted accounting principles (“GAAP”) and prevailing industry practices.

The accompanying consolidated financial statements are unaudited. In the opinion of management, all adjustments necessary for a fair presentation of financial position, results of operations and cash flows for the periods have been made. These financial statements should be read in conjunction with BNY Mellon’s Annual Report on Form 10-K for the year ended Dec. 31, 2012. Certain immaterial reclassifications have been made to prior periods to place them on a basis comparable with current period presentation.

Use of estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates based upon assumptions about future economic and market conditions which affect reported amounts and related disclosures in our financial statements. Although our current estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that actual conditions could be worse than anticipated in those estimates, which could materially affect our results of operations and financial condition. Amounts subject to estimates are items such as the allowance for loan losses and lending-related commitments, the fair value of financial instruments and other-than-temporary impairments, goodwill and intangible assets and pension accounting. Among other effects, such changes in estimates could result in future impairments of investment securities, goodwill and intangible assets and establishment of allowances for loan losses and lending-related commitments as well as changes in pension and post-retirement expense.

Note 2 - Accounting changes and new accounting guidance

ASU 2011-11 - Disclosures about Offsetting Assets and Liabilities

In December 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU 2011-11”), “Disclosures about Offsetting Assets and Liabilities”. Entities are required to disclose both gross information and net information about both instruments and transactions eligible for offset in the balance sheet and instruments and transactions subject to an agreement similar to a master netting arrangement. This scope would include derivatives, sale and repurchase agreements and reverse sale and repurchase agreements, and securities borrowing and securities lending arrangements. See Note 17 “Derivative instruments” for our disclosure.

ASU 2012-02 - Testing Indefinite-Lived Intangible Assets for Impairment

In July 2012, the FASB issued ASU 2012-02, “Testing Indefinite-Lived Intangible Assets for Impairment”. This guidance allows an entity an option to first assess qualitative factors to determine whether it is more likely than not (a likelihood of more than 50 percent) that an indefinite-lived intangible asset is impaired. If the intangible asset is impaired, an entity is required to perform the quantitative impairment test. An entity is not required to calculate the fair value of an indefinite-lived intangible asset and perform the quantitative impairment test unless the entity determines that it is more likely than not that the asset is impaired.

ASU 2013-02 - Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income

In February 2013, the FASB issued ASU 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income”. This ASU requires the presentation of the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income. See Note 14 “Other comprehensive income (loss)” for our disclosure.

Notes to Consolidated Financial Statements(continued)

Note 3—Acquisitions

We sometimes structure our acquisitions with both an initial payment and later contingent payments tied to post-closing revenue or income growth. For acquisitions completed prior to Jan. 1, 2009, we record the fair value of contingent payments as an additional cost of the entity acquired in the period that the payment becomes probable. For acquisitions completed after Jan. 1, 2009, subsequent changes in the fair value of a contingent consideration liability are recorded through the income statement. Contingent payments totaled $4 million in the first quarter of 2013.

At March 31, 2013, we were potentially obligated to pay additional consideration which, using reasonable assumptions for the performance of the acquired companies and joint ventures based on contractual agreements, could range from $11 million to $24 million over the next two years.

Acquisitions in 2012

On Oct 1, 2012, BNY Mellon acquired the remaining 50% interest of the WestLB Mellon Asset Management joint venture for cash of $22 million. We later renamed the unit Meriten Investment Management GmbH (“Meriten”). We are obligated to pay, upon occurrence of certain events, contingent additional consideration of up to $13 million. Goodwill related to this acquisition, including the fair value of the contingent additional consideration, totaled $70 million and is included in our Investment Management business. This goodwill is not deductible for tax purposes. Customer relationship intangible assets related to this acquisition are included in our Investment Management business, with a life of eight years, and totaled $23 million.

Other-than-temporary impairment

We routinely conduct periodic reviews of all securities using economic models to identify and evaluate each investment security to determine whether OTTI has occurred. Various inputs to the economic models are used to determine if an unrealized loss on securities is other-than-temporary. For example, the most significant inputs related to non-agency RMBS are:

• Default rate - the number of mortgage loans expected to go into default over the life of the transaction, which is driven by the roll rate of loans in each performance bucket that will ultimately migrate to default; and

• Severity - the loss expected to be realized when a loan defaults.

To determine if an unrealized loss is other-than-temporary, we project total estimated defaults of the underlying assets (mortgages) and multiply that calculated amount by an estimate of realizable value upon sale of these assets in the marketplace (severity) in order to determine the projected collateral loss. We also evaluate the current credit enhancement underlying the bond to determine the impact on cash flows. If we determine that a given security will be subject to a write-down or loss, we

record the expected credit loss as a charge to earnings.

In addition, we have estimated the expected loss by taking into account observed performance of the underlying securities, industry studies, market forecasts, as well as our view of the economic outlook affecting collateral.

The table below shows the projected weighted-average default rates and loss severities for the 2007, 2006 and late 2005 non-agency RMBS and the securities previously held in the Grantor Trust we established in connection with the restructuring of our investment securities portfolio in 2009, at March 31, 2013 and Dec. 31, 2012.

Troubled debt restructurings (“TDRs”)

A modified loan is considered a TDR if the debtor is experiencing financial difficulties and the creditor grants a concession to the debtor that would not

otherwise be considered. A TDR may include a transfer of real estate or other assets from the debtor to the creditor, or a modification of the term of the loan. Not all modified loans are considered TDRs.

The following table presents TDRs that occurred in the first quarter of 2013, the fourth quarter of 2012 and the first quarter of 2012.

TDRs	March 31, 2013					Dec. 31, 2012					March 31, 2012

Other residential mortgages

The modifications of the other residential mortgage loans in the first quarter of 2013, fourth quarter of 2012 and first quarter of 2012 consisted of reducing the stated interest rates, and in certain cases, a forbearance of default and extending the maturity dates. The value of modified loans is based on the fair value of the collateral. Probable loss factors are applied to the value of the modified loans to determine the allowance for credit losses.

Wealth management loans and mortgages

The modifications of the wealth management loans and mortgages in the fourth quarter of 2012 consisted of changes in payment terms and extensions of the maturity dates. The difference between the book value of the loan and the estimated fair value of the collateral is included in the allowance for credit losses.

73 BNY Mellon

Notes to Consolidated Financial Statements(continued)

Commercial

The modification of the commercial exposure in the first quarter of 2012 consisted of changing the stated interest rates and/or extending the maturity dates of the loans. The difference between the book value of the loan and net cash flow discounted at the original loan’s rate, if no observable market price exists, is included in the allowance for credit losses.

Commercial real estate

The modifications of the commercial real estate loans and unfunded lending-related commitments in first quarter of 2012 consisted of changing the stated interest rates and extending the maturity dates of the loans. The difference between the book value of the loan and the estimated fair value of the collateral is included in the allowance for credit losses.

Foreign

The modifications of foreign loans in the first quarter of 2012 consisted of extending the maturity date of the loan. The difference between the book value of the loan and the net present value

discounted at the original loan’s rate is included in the allowance for credit losses.

TDRs that subsequently defaulted

There were 15 residential mortgage loans that had been restructured in a TDR during the previous 12 months and have subsequently defaulted in the first quarter of 2013. The total recorded investment of these loans was $4 million.

Credit quality indicators

Our credit strategy is to focus on investment grade names to support cross-selling opportunities and avoid single name/industry concentrations. Each customer is assigned an internal credit rating which is mapped to an external rating agency grade equivalent based upon a number of dimensions which are continually evaluated and may change over time.

The following tables set forth information about credit quality indicators.

Commercial loan portfolio

Commercial loan portfolio – Credit risk profile by creditworthiness category
	Commercial				Commercial real estate				Financial institutions
(in millions)	March 31, 2013		Dec. 31, 2012		March 31, 2013		Dec. 31, 2012		March 31, 2013		Dec 31, 2012

Total	$	1,480	$	1,417	$	1,874	$	1,740	$	13,784	$	11,288

The commercial loan portfolio is divided into investment grade and non-investment grade categories based on rating criteria largely consistent with those of the public rating agencies. Each customer in the portfolio is assigned an internal credit rating. These internal credit ratings are generally consistent with the ratings categories of the public rating agencies. Customers with ratings consistent with BBB- (S&P)/Baa3 (Moody’s) or better are considered to be investment grade. Those clients with ratings lower than this threshold are considered to be non-investment grade.

Wealth management loans and mortgages

Wealth management loans and mortgages – Credit risk profile by internally assigned grade

Wealth management mortgages	4,287		4,142
Total	$	8,991	$	8,864

Wealth management non-mortgage loans are not typically rated by external rating agencies. A majority of the wealth management loans are secured by the customers’ investment management accounts or custody accounts. Eligible assets

BNY Mellon 74

Notes to Consolidated Financial Statements(continued)

pledged for these loans are typically investment-grade, fixed-income securities, equities and/or mutual funds. Internal ratings for this portion of the wealth management portfolio, therefore, would equate to investment-grade external ratings. Wealth management loans are provided to select customers based on the pledge of other types of assets, including business assets, fixed assets or a modest amount of commercial real estate. For the loans collateralized by other assets, the credit quality of the obligor is carefully analyzed, but we do not consider this portfolio of loans to be investment grade.

Credit quality indicators for wealth management mortgages are not correlated to external ratings. Wealth management mortgages are typically loans to high-net-worth individuals, which are secured primarily by residential property. These loans are primarily interest-only adjustable rate mortgages with an average loan-to-value ratio of 63% at origination. In the wealth management portfolio, less than 1% of the mortgages were past due at March 31, 2013.

At March 31, 2013, the private wealth mortgage portfolio was comprised of the following geographic concentrations: New York - 22%; California - 20%; Massachusetts - 16%; Florida - 8%; and other - 34%.

Other residential mortgages

The other residential mortgage portfolio primarily consists of 1-4 family residential mortgage loans and totaled $1,570 million at March 31, 2013 and $1,632 million at Dec. 31, 2012. These loans are not typically correlated to external ratings. Included in this portfolio at March 31, 2013 are $480 million of mortgage loans purchased in 2005, 2006 and the first quarter of 2007 that are predominantly prime mortgage loans, with a small portion of Alt-A loans. As of March 31, 2013, the purchased loans in this portfolio had a weighted-average loan-to-value ratio of 75% at origination and 23% of these loans were at least 60 days delinquent. The properties securing the prime and Alt-A mortgage loans were located (in order of concentration) in California, Florida, Virginia, Maryland and the tri-state area (New York, New Jersey and Connecticut).

Overdrafts

Overdrafts primarily relate to custody and securities clearance clients and totaled $5,319 million at March 31, 2013 and $5,298 million at Dec. 31, 2012. Overdrafts occur on a daily basis in the custody and securities clearance business and are generally repaid within two business days.

Margin loans

We had $13,242 million of secured margin loans on our balance sheet at March 31, 2013 compared with $13,397 million at Dec. 31, 2012. Margin loans are collateralized with marketable securities and borrowers are required to maintain a daily collateral margin in excess of 100% of the value of the loan. We have rarely suffered a loss on these types of loans and do not allocate any of our allowance for credit losses to margin loans.

Other loans

Other loans primarily includes loans to consumers that are fully collateralized with equities, mutual funds and fixed income securities, as well as bankers’ acceptances.

Reverse repurchase agreements

Reverse repurchase agreements are transactions fully collateralized with high-quality liquid securities. These transactions carry minimal credit risk and therefore are not allocated an allowance for credit losses.

Note 6 - Goodwill and intangible assets

Impairment testing

Goodwill impairment testing is performed at least annually at the reporting unit level. Intangible assets not subject to amortization are tested annually for impairment or more often if events or circumstances indicate they may be impaired.

Goodwill

Seed capital and private equity investments valued using net asset value per share

In our Investment Management business, we manage investment assets, including equities, fixed income, money market and alternative investment funds for institutions and other investors. As part of that activity we make seed capital investments in certain funds. BNY Mellon also holds private equity investments, which consist of investments in private equity funds, mezzanine financings and direct equity investments. Seed capital and private equity investments are included in other assets. Consistent with our policy to focus on our core activities, we continue to reduce our exposure to private equity investments.

The fair value of these investments has been estimated using the net asset value (“NAV”) per share of BNY Mellon’s ownership interest in the funds. The table below presents information about BNY Mellon’s investments in seed capital and private equity investments.

Severance payments are primarily paid over the salary continuance period in accordance with the separation plan.

Operational excellence initiatives

In 2011, we announced our operational excellence initiatives which include an expense reduction initiative impacting approximately 1,500 positions, as well as additional initiatives to transform operations, technology and corporate services that will increase productivity and reduce the growth rate of expenses. We recorded a pre-tax restructuring charge of $107 million related to the operational

As previously disclosed, on Nov. 10, 2009 BNY Mellon filed a petition with the U.S. Tax Court challenging the IRS’ disallowance of certain foreign

tax credits claimed for the 2001 and 2002 tax years. Trial was held from April 16 to May 17, 2012. On Feb. 11, 2013, BNY Mellon received an adverse decision from the U.S. Tax Court.  We continue to believe the tax treatment of the transaction was correct and will appeal the Court’s decision. As a result of the ruling and in accordance with the accounting for uncertain tax positions under ASC 740, BNY Mellon recorded a tax charge of $854 million in the first quarter of 2013.

Our total tax reserves as of March 31, 2013 were $1,050 million compared with $340 million at Dec. 31, 2012. If these tax reserves were unnecessary, $1,050 million would affect the effective tax rate in future periods. We recognize accrued interest and penalties, if applicable, related to income taxes in income tax expense. Included in the balance sheet at March 31, 2013 is accrued interest, where applicable, of $323 million. The additional tax expense related to interest for the three months endedMarch 31, 2013 was $289 million compared with $3 million for the three months endedMarch 31, 2012.

It is reasonably possible the total reserve for uncertain tax positions could decrease within the next 12 months by an amount up to $72 million as a result of adjustments related to tax years that are still subject to examination.

Our federal income tax returns are closed to examination for all periods through 2002. The years 2003 through 2006 remain open to examination. The years 2007 and 2008 are closed for further examination, however one matter is before the Internal Revenue Service (“IRS”) appeals. Our New York State and New York City income tax returns are closed to examination through 2010. Our UK income tax returns are closed to examination through 2008.

Note 12 - Securitizations and variable interest entities

BNY Mellon’s VIEs generally include retail, institutional and alternative investment funds offered to its retail and institutional customers in which it acts as the fund’s investment manager. BNY Mellon earns management fees on these funds as well as performance fees in certain funds. It may also provide start-up capital in its new funds. These VIEs are included in the scope of ASU 2010-10 and

Note 15 - Fair value measurement

The guidance related to “Fair Value Measurement” included in ASC 820 defines fair value as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date and establishes a framework for measuring fair value. It establishes a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date and expands the disclosures about instruments measured at fair value. ASC 820 requires consideration of a company’s own creditworthiness when valuing liabilities.

The standard provides a consistent definition of fair value, which focuses on exit price in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple

valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The objective is to determine from weighted indicators of fair value a reasonable point within the range that is most representative of fair value under current market conditions.

Determination of fair value

Following is a description of our valuation methodologies for assets and liabilities measured at fair value. We have established processes for determining fair values. Fair value is based upon quoted market prices in active markets, where available. For financial instruments where quotes from recent exchange transactions are not available, we determine fair value based on discounted cash flow analysis, comparison to similar instruments, and the use of financial models. Discounted cash flow analysis is dependent upon estimated future

BNY Mellon 82

Notes to Consolidated Financial Statements(continued)

cash flows and the level of interest rates. Model-based pricing uses inputs of observable prices, where available, for interest rates, foreign exchange rates, option volatilities and other factors. Models are benchmarked and validated by an independent internal risk management function. Our valuation process takes into consideration factors such as counterparty credit quality, liquidity, concentration concerns, and observability of model parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value.

Most derivative contracts are valued using internally developed models which are calibrated to observable market data and employ standard market pricing theory for their valuations. An initial “risk-neutral” valuation is performed on each position assuming time-discounting based on a AA credit curve. Then, to arrive at a fair value that incorporates counter-party credit risk, a credit adjustment is made to these results by discounting each trade’s expected exposures to the counterparty using the counterparty’s credit spreads, as implied by the credit default swap market. We also adjust expected liabilities to the counterparty using BNY Mellon’sown credit spreads, as implied by the credit default swap market. Accordingly, the valuation of our derivative position is sensitive to the current changes in our own credit spreads as well as those of our counterparties.

In certain cases, recent prices may not be observable for instruments that trade in inactive or less active markets. Upon evaluating the uncertainty in valuing financial instruments subject to liquidity issues, we make an adjustment to their value. The determination of the liquidity adjustment includes the availability of external quotes, the time since the latest available quote and the price volatility of the instrument.

Certain parameters in some financial models are not directly observable and, therefore, are based on management’s estimates and judgments. These financial instruments are normally traded less actively. We apply valuation adjustments to mitigate the possibility of error and revision in the model based estimate value. Examples include products where parameters such as correlation and recovery rates are unobservable.

The methods described above for instruments that trade in inactive or less active markets may produce

a current fair value calculation that may not be indicative of net realizable value or reflective of future fair values. We believe our methods of determining fair value are appropriate and consistent with other market participants. However, the use of different methodologies or different assumptions to value certain financial instruments could result in a different estimate of fair value.

Valuation hierarchy

ASC 820 established a three-level valuation hierarchy for disclosure of fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are described below.

Level 1: Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 1 assets and liabilities include debt and equity securities and derivative financial instruments actively traded on exchanges and U.S. Treasury securities that are actively traded in highly liquid over-the-counter markets.

Level 2: Observable inputs other than Level 1 prices, for example, quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs that are observable or can be corroborated, either directly or indirectly, for substantially the full term of the financial instrument. Level 2 assets and liabilities include debt instruments that are traded less frequently than exchange-traded securities and derivative instruments whose model inputs are observable in the market or can be corroborated by market-observable data. Examples in this category are agency and non-agency mortgage-backed securities, corporate debt securities and over-the-counter derivative contracts.

Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement. Examples in this category include certain private equity investments, derivative contracts that are highly structured or long-dated, and interests in certain securitized financial assets.

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of

83 BNY Mellon

Notes to Consolidated Financial Statements(continued)

input that is significant to the fair value measurement.

Following is a description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy.

Securities

Where quoted prices are available in an active market, we classify the securities within Level 1 of the valuation hierarchy. Securities include both long and short positions. Level 1 securities include highly liquid government bonds, money market mutual funds and exchange-traded equities.

If quoted market prices are not available, we estimate fair values using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. Examples of such instruments, which would generally be classified within Level 2 of the valuation hierarchy, include agency and non-agency mortgage-backed securities, commercial mortgage-backed securities, sovereign debt, corporate bonds and foreign covered bonds.

For securities where quotes from recent transactions are not available for identical securities, wedetermine fair value primarily based on pricing sources with reasonable levels of price transparency that employ financial models or obtain comparison to similar instruments to arrive at “consensus” prices.

Specifically, the pricing sources obtain recent transactions for similar types of securities (e.g., vintage, position in the securitization structure) and ascertain variables such as discount rate and speed of prepayment for the types of transaction and apply such variables to similar types of bonds. We view these as observable transactions in the current marketplace and classify such securities as Level 2. Pricing sources discontinue pricing any specific security whenever they determine there is insufficient observable data to provide a good faith opinion on price.

In addition, we have significant investments in more actively traded agency RMBS and other types of securities such as sovereign debt. The pricing sources derive the prices for these securities largely from quotes they obtain from three major inter-

dealer brokers. The pricing sources receive their daily observed trade price and other information feeds from the inter-dealer brokers.

For securities with bond insurance, the financial strength of the insurance provider is analyzed and that information is included in the fair value assessment for such securities.

In certain cases where there is limited activity or less transparency around inputs to the valuation, we classify those securities in Level 3 of the valuation hierarchy. Securities classified within Level 3 primarily include securities of state and political subdivisions and distressed debt securities.

At March 31, 2013, more than 99% of our securities were valued by pricing sources with reasonable levels of price transparency. Less than 1% of our securities were priced based on economic models and non-binding dealer quotes, and are included in Level 3 of the ASC 820 hierarchy.

Consolidated collateralized loan obligations

BNY Mellon values assets in consolidated CLOs using observable market prices observed from the secondary loan market. The returns to the note holders are solely dependent on the assets and accordingly equal the value of those assets. Based on the structure of the CLOs, the valuation of the assets is attributable to the senior note holders. Changes in the values of assets and liabilities are reflected in the income statement as investment income and interest of investment management fund note holders, respectively.

Derivatives

We classify exchange-traded derivatives valued using quoted prices in Level 1 of the valuation hierarchy. Examples include exchanged-traded equity and foreign exchange options. Since few other classes of derivative contracts are listed on an exchange, most of our derivative positions are valued using internally developed models that use as their basis readily observable market parameters, and we classify them in Level 2 of the valuation hierarchy. Such derivatives include basic swaps and options and credit default swaps.

Derivatives valued using models with significant unobservable market parameters in markets that lack

two-way flow are classified in Level 3 of the valuation hierarchy. Examples include long-dated interest rate or currency swaps and options, where parameters may be unobservable for longer maturities; and certain products, where correlation risk is unobservable. The fair value of these derivatives compose less than 1% of our derivative financial instruments. Additional disclosures of derivative instruments are provided in Note 17 of the Notes to Consolidated Financial Statements.

Loans and unfunded lending-related commitments

Where quoted market prices are not available, we generally base the fair value of loans and unfunded lending-related commitments on observable market prices of similar instruments, including bonds, credit derivatives and loans with similar characteristics. If observable market prices are not available, we base the fair value on estimated cash flows adjusted for credit risk which are discounted using an interest rate appropriate for the maturity of the applicable loans or the unfunded lending-related commitments.

Unrealized gains and losses, if any, on unfunded lending-related commitments carried at fair value are classified in Other assets and Other liabilities, respectively. Loans and unfunded lending-related commitments carried at fair value are generally classified within Level 2 of the valuation hierarchy.

Seed capital

In our Investment Management business, we manage investment assets, including equities, fixed income, money market and alternative investment funds for institutions and other investors. As part of that activity, we make seed capital investments in certain funds. Seed capital is included in other assets. When applicable, we value seed capital based on the published NAV of the fund. We include funds in which ownership interests in the fund are publicly traded in an active market and institutional funds in which investors trade in and out daily in Level 1 of the valuation hierarchy. We include open-end funds where investors are allowed to sell their ownership interest back to the fund less frequently than daily and where our interest in the fund contains no other rights or obligations in Level 2 of the valuation hierarchy. However, we generally include investments in funds that allow investors to sell their ownership interest back to the fund less frequently

than monthly in Level 3, unless actual redemption prices are observable.

For other types of investments in funds, we consider all of the rights and obligations inherent in our ownership interest, including the reported NAV as well as other factors that affect the fair value of our interest in the fund. To the extent the NAV measurements reported for the investments are based on unobservable inputs or include other rights and obligations (e.g., obligation to meet cash calls), we generally classify them in Level 3 of the valuation hierarchy.

Certain interests in securitizations

For certain interests in securitizations that are classified in securities available-for-sale, trading assets and long-term debt, we use discounted cash flow models, which generally include assumptions of projected finance charges related to the securitized assets, estimated net credit losses, prepayment assumptions and estimates of payments to third-party investors. When available, we compare our fair value estimates and assumptions to market activity and to the actual results of the securitized portfolio.

Private equity investments

Our Other segment includes holdings of nonpublic private equity investment through funds managed by third-party investment managers. We value private equity investments initially based upon the transaction price, which we subsequently adjust to reflect expected exit values as evidenced by financing and sale transactions with third parties or through ongoing reviews by the investment managers.

Private equity investments also include publicly held equity investments, generally obtained through the initial public offering of privately held equity investments. These equity investments are often held in a partnership structure. Publicly held investments are marked-to-market at the quoted public value less adjustments for regulatory or contractual sales restrictions or adjustments to reflect the difficulty in selling a partnership interest.

Discounts for restrictions are quantified by analyzing the length of the restriction period and the volatility of the equity security. Publicly held private equity

investments are primarily classified in Level 2 of the valuation hierarchy.

The following tables present the financial instruments carried at fair value at March 31, 2013 and Dec. 31 2012, by caption on the consolidated balance sheet and by ASC 820 valuation hierarchy

(as described above). We have included credit ratings information in certain of the tables because the information indicates the degree of credit risk to which we are exposed, and significant changes in ratings classifications could result in increased risk for us. There were no material transfers between Level 1 and Level 2 during the first quarter of 2013.

Changes in Level 3 fair value measurements

Our classification of a financial instrument in Level 3 of the valuation hierarchy is based on the significance of the unobservable factors to the overall fair value measurement. However, these instruments generally include other observable components that are actively quoted or validated to third-party sources; accordingly, the gains and losses in the table below include changes in fair value due to observable parameters as well as the unobservable parameters in our valuation methodologies. We also frequently manage the risks of Level 3 financial instruments using securities and derivatives positions that are Level 1 or 2 instruments which are

not included in the table; accordingly, the gains or losses below do not reflect the effect of our risk management activities related to the Level 3 instruments.

The Company has a Level 3 Pricing Committee which evaluates the valuation techniques used in determining the fair value of Level 3 assets and liabilities.

The tables below include a roll forward of the balance sheet amounts for the quarter ended March 31, 2013 and 2012 (including the change in fair value), for financial instruments classified in Level 3 of the valuation hierarchy.

Assets and liabilities measured at fair value on a nonrecurring basis

Under certain circumstances, we make adjustments to fair value our assets, liabilities and unfunded lending-related commitments although they are not measured at fair value on an ongoing basis. An example would be the recording of an impairment of an asset.

The following table presents the financial instruments carried on the consolidated balance sheet by caption and by level in the fair value hierarchy as of March 31, 2013 and Dec. 31, 2012, for which a nonrecurring change in fair value has been recorded during the quarters ended March 31, 2013 and Dec. 31, 2012.

Estimated fair value of financial instruments

The carrying amounts of our financial instruments (i.e., monetary assets and liabilities) are determined under different accounting methods - see Note 1 of the Notes to Consolidated Financial Statements in our 2012 Annual Report. The following disclosure discusses these instruments on a uniform fair value basis. However, active markets do not exist for a significant portion of these instruments. For financial instruments where quoted prices from identical assets and liabilities in active markets do not exist, we determine fair value based on discounted cash flow analysis and comparison to similar instruments. Discounted cash flow analysis is dependent upon estimated future cash flows and the level of interest rates. Other judgments would result in different fair values. The assumptions we used at March 31, 2013 and Dec. 31, 2012 include discount rates ranging principally from 0.20% to 4.87%. The fair value information supplements the basic financial statements and other traditional financial data presented throughout this report.

A summary of the practices used for determining fair value and the respective level in the valuation hierarchy for financial assets and liabilities not recorded at fair value follows.

Interest-bearing deposits with the Federal Reserve and other central banks and interest-bearing deposits with banks

The estimated fair value of interest-bearing deposits with the Federal Reserve and other central banks is equal to the book value as these interest-bearing deposits are generally considered cash equivalents. These instruments are classified as Level 2 within the valuation hierarchy. The estimated fair value of interest-bearing deposits with banks is generally determined using discounted cash flows and duration of the instrument to maturity. The primary inputs used to value these transactions are interest rates based on current LIBOR market rates and time to maturity. Interest-bearing deposits with banks are classified as Level 2 within the valuation hierarchy.

Federal funds sold and securities purchased under resale agreements

The estimated fair value of federal funds sold and securities purchased under resale agreements is based on inputs such as interest rates and tenors.

Federal funds sold and securities purchased under resale agreements are classified as Level 2 within the valuation hierarchy.

Securities held-to-maturity

Where quoted prices are available in an active market for identical assets and liabilities, we classify the securities as Level 1 within the valuation hierarchy. Securities are defined as both long and short positions. Level 1 securities include U.S. Treasury securities.

If quoted market prices are not available for identical assets and liabilities, we estimate fair value using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. Examples of such instruments, which would generally be classified as Level 2 within the valuation hierarchy, include certain agency and non-agency mortgage-backed securities, commercial mortgage-backed securities and state and political subdivision securities. For securities where quotes from active markets are not available for identical securities, we determine fair value primarily based on pricing sources with reasonable levels of price transparency that employ financial models or obtain comparison to similar instruments to arrive at “consensus” prices.

Specifically, the pricing sources obtain active market prices for similar types of securities (e.g., vintage, position in the securitization structure) and ascertain variables such as discount rate and speed of prepayment for the types of transaction and apply such variables to similar types of bonds. We view these as observable transactions in the current marketplace and classify such securities as Level 2 within the valuation hierarchy.

Loans

For residential mortgage loans, fair value is estimated using discounted cash flow analysis, adjusting where appropriate for prepayment estimates, using interest rates currently being offered for loans with similar terms and maturities to borrowers. The estimated fair value of margin loans and overdrafts is equal to the book value due to the short-term nature of these assets. The estimated fair value of other types of loans is determined using discounted cash flows. Inputs include current LIBOR market rates adjusted for credit spreads.

BNY Mellon 94

Notes to Consolidated Financial Statements(continued)

These loans are generally classified as Level 2 within the valuation hierarchy.

Other financial assets

Other financial assets include cash, the Federal Reserve Bank stock and accrued interest receivable. Cash is classified as Level 1 within the valuation hierarchy. The Federal Reserve Bank stock is not redeemable or transferable. The estimated fair value of the Federal Reserve Bank stock is based on the issue price and is classified as Level 2 within the valuation hierarchy. Accrued interest receivable is generally short-term. As a result, book value is considered to equal fair value. Accrued interest receivable is included as Level 2 within the valuation hierarchy.

Noninterest-bearing and interest-bearing deposits

Interest-bearing deposits are comprised of money market rate and demand deposits, savings deposits and time deposits. Except for time deposits, book value is considered to equal fair value for these deposits due to their short duration to maturity or payable on demand feature. The fair value of interest-bearing time deposits is determined using discounted cash flow analysis. Inputs primarily consist of current LIBOR market rates and time to maturity. For all noninterest-bearing deposits, book value is considered to equal fair value as a result of the short duration of the deposit. Interest-bearing and noninterest-bearing deposits are classified as Level 2 within the valuation hierarchy.

Federal funds purchased and securities sold under repurchase agreements

The estimated fair value of federal funds purchased and securities sold under repurchase agreements is based on inputs such as interest rates and tenors. Federal funds purchased and securities sold under

repurchase agreements are classified as Level 2 within the valuation hierarchy.

Payables to customers and broker-dealers

The estimated fair value of payables to customers and broker-dealers is equal to the book value, due to the demand feature of the payables to customers and broker-dealers, and are classified as Level 2 within the valuation hierarchy.

Borrowings

Borrowings primarily consist of overdrafts of subcustodian account balances in our Investment Services businesses, commercial paper and accrued interest payable. The estimated fair value of overdrafts of subcustodian account balances in our Investment Services businesses is considered to equal book value as a result of the short duration of the overdrafts. Overdrafts are typically repaid within two days. The estimated fair value of our commercial paper is based on discount and duration of the commercial paper. Our commercial paper matures within 397 days from date of issue and is not redeemable prior to maturity or subject to voluntary prepayment. Our commercial paper is included in Level 2 of the valuation hierarchy. Accrued interest payable is generally short-term. As a result, book value is considered to equal fair value. Accrued interest payable is included as Level 2 within the valuation hierarchy.

Long-term debt

The estimated fair value of long-term debt is based on current rates for instruments of the same remaining maturity or quoted market prices for the same or similar issues. Long-term debt is classified as Level 2 within the valuation hierarchy.

BNY Mellon values assets in consolidated CLOs using observable market prices observed from the secondary loan market. The returns to the note holders are solely dependent on the assets and accordingly equal the value of those assets. Mark-to-market valuation best reflects the limited interest BNY Mellon has in the economic performance of the consolidated CLOs. Changes in the values of assets and liabilities are reflected in the income statement as investment income of consolidated investment management funds.

We have elected the fair value option on $240 million of long-term debt in connection with ASC 810. At March 31, 2013, the fair value of this long-term debt was $341 million. The long-term debt is valued using observable market inputs and is included in Level 2 of the ASC 820 hierarchy.

The following table presents the changes in fair value of the long-term debt included in foreign exchange and other trading revenue in the consolidated income statement.

(a) The change in fair value of the long-term debt is approximately offset by an economic hedge included in trading.

Note 17 - Derivative instruments

We use derivatives to manage exposure to market risk including interest rate risk, equity price risk and foreign currency risk, as well as credit risk. Our trading activities are focused on acting as a market-maker for our customers and facilitating customer trades. In addition, we periodically manage positions for our own account. Positions managed for our own account are immaterial to our foreign exchange and other trading revenue and to our overall results of operations.

The notional amounts for derivative financial instruments express the dollar volume of the

97 BNY Mellon

Notes to Consolidated Financial Statements(continued)

transactions; however, credit risk is much smaller. We perform credit reviews and enter into netting agreements to minimize the credit risk of derivative financial instruments. We enter into offsetting positions to reduce exposure to foreign currency, interest rate and equity price risk.

Use of derivative financial instruments involves reliance on counterparties. Failure of a counterparty to honor its obligation under a derivative contract is a risk we assume whenever we engage in a derivative contract. There were no counterparty default losses in the first quarter of 2013. Counterparty default losses were less than $1 million in the first quarter of 2012.

Hedging derivatives

We utilize interest rate swap agreements to manage our exposure to interest rate fluctuations. For hedges of available-for-sale investment securities, deposits and long-term debt, the hedge documentation specifies the terms of the hedged items and the interest rate swaps and indicates that the derivative is hedging a fixed rate item and is a fair value hedge, that the hedge exposure is to the changes in the fair value of the hedged item due to changes in benchmark interest rates, and that the strategy is to eliminate fair value variability by converting fixed-rate interest payments to LIBOR.

The available-for-sale investment securities hedged consist of sovereign debt and U.S. Treasury bonds that had original maturities of 30 years or less at initial purchase. The swaps on the sovereign debt and U.S. Treasury bonds are not callable. All of these securities are hedged with “pay fixed rate, receive variable rate” swaps of similar maturity, repricing and fixed rate coupon. At March 31, 2013, $5.9 billion face amount of securities were hedged with interest rate swaps that had notional values of $6.1 billion.

The hedged fixed rate deposits have original maturities of approximately ten years and are not callable. These deposits are hedged with “receive fixed rate, pay variable” rate swaps of similar maturity, repricing and fixed rate coupon. The swaps are not callable. At March 31, 2013, $10 million face amount of deposits were hedged with interest rate swaps that had notional values of $10 million.

The fixed rate long-term debt instruments hedged generally have original maturities of five to 30 years. We issue both callable and non-callable debt. The non-callable debt is hedged with simple interest rate swaps similar to those described for deposits. Callable debt is hedged with callable swaps where the call dates of the swaps exactly match the call dates of the debt. At March 31, 2013, $14 billion par value of debt was hedged with interest rate swaps that had notional values of $14 billion.

In addition, we enter into foreign exchange hedges. We use forward foreign exchange contracts with maturities of nine months or less to hedge our British Pound, Euro, Hong Kong Dollar, Indian Rupee and Singapore Dollar foreign exchange exposure with respect to foreign currency forecasted revenue and expense transactions in entities that have the U.S. dollar as their functional currency. As of March 31, 2013, the hedged forecasted foreign currency transactions and designated forward foreign exchange contract hedges were $139 million (notional), with a pre-tax gain of less than $1 million recorded in accumulated other comprehensive income. This gain will be reclassified to income or expense over the next nine months.

We use forward foreign exchange contracts with remaining maturities of nine months or less as hedges against our foreign exchange exposure to Australian Dollar, Euro, Swedish Krona, British Pound, Danish Krone, Norwegian Krone and Japanese Yen with respect to interest-bearing deposits with banks and their associated forecasted interest revenue. These hedges are designated as cash flow hedges. These hedges are effected such that their maturities and notional values match those of the deposits with banks. As of March 31, 2013, the hedged interest-bearing deposits with banks and their designated forward foreign exchange contract hedges were $6.9 billion (notional), with a pre-tax gain of less than $1 million recorded in accumulated other comprehensive income. This gain will be reclassified to net interest revenue over the next nine months.

Forward foreign exchange contracts are also used to hedge the value of our net investments in foreign subsidiaries. These forward foreign exchange contracts have maturities of less than two years. The derivatives employed are designated as hedges of changes in value of our foreign investments due to exchange rates. Changes in the value of the forward

BNY Mellon 98

Notes to Consolidated Financial Statements(continued)

foreign exchange contracts offset the changes in value of the foreign investments due to changes in foreign exchange rates. The change in fair market value of these forward foreign exchange contracts is deferred and reported within accumulated translation adjustments in shareholders’ equity, net of tax. At March 31, 2013, forward foreign exchange contracts with notional amounts totaling $5.2 billion were designated as hedges.

In addition to forward foreign exchange contracts, we also designate non-derivative financial instruments as hedges of our net investments in foreign subsidiaries. Those non-derivative financial instruments designated as hedges of our net investments in foreign subsidiaries were all long-term liabilities of BNY Mellon in various currencies,

and, at March 31, 2013, had a combined U.S. dollar equivalent value of $500 million.

Trading activities (including trading derivatives)

We manage trading risk through a system of position limits, a VaR methodology based on Monte Carlo simulations, stop loss advisory triggers, and other market sensitivity measures. Risk is monitored and reported to senior management by a separate unit on a daily basis. Based on certain assumptions, the VaR methodology is designed to capture the potential overnight pre-tax dollar loss from adverse changes in fair values of all trading positions. The calculation assumes a one-day holding period for most instruments, utilizes a 99% confidence level, and incorporates the non-linear characteristics of options. The VaR model is one of several statistical models used to develop economic capital results, which is allocated to lines of business for computing risk-adjusted performance.

As the VaR methodology does not evaluate risk attributable to extraordinary financial, economic or other occurrences, the risk assessment process includes a number of stress scenarios based upon the risk factors in the portfolio and management’s assessment of market conditions. Additional stress

scenarios based upon historic market events are also performed. Stress tests, by their design, incorporate the impact of reduced liquidity and the breakdown of observed correlations. The results of these stress tests are reviewed weekly with senior management.

Revenue from foreign exchange and other trading included the following:

primarily includes revenue from equity securities and equity derivatives.

Counterparty credit risk and collateral

We assess credit risk of our counterparties through regular examination of their financial statements, confidential communication with the management of those counterparties and regular monitoring of publicly available credit rating information. This and other information is used to develop proprietary credit rating metrics used to assess credit quality.

Collateral requirements are determined after a comprehensive review of the credit quality of each counterparty. Collateral is generally held or pledged in the form of cash or highly liquid government securities. Collateral requirements are monitored and adjusted daily.

Additional disclosures concerning derivative financial instruments are provided in Note 15 of the Notes to Consolidated Financial Statements.

Disclosure of contingent features in over-the-counter (“OTC”) derivative instruments

Certain OTC derivative contracts and/or collateral agreements of The Bank of New York Mellon, our largest banking subsidiary and the subsidiary through which BNY Mellon enters into the substantial majority of all of its OTC derivative contracts and/or collateral agreements, contain provisions that may require us to take certain actions if The Bank of New York Mellon’s public debt rating fell to a certain level. Early termination provisions,

or “close-out” agreements, in those contracts could trigger immediate payment of outstanding contracts that are in net liability positions. Certain collateral agreements would require The Bank of New York Mellon to immediately post additional collateral to cover some or all of The Bank of New York Mellon’s liabilities to a counterparty.

The following table shows the fair value of contracts falling under early termination provisions that were in net liability positions as of March 31, 2013 for three key ratings triggers:

If The Bank of New York Mellon’s rating was changed to (Moody’s/S&P)	Potential close-out exposures (fair value) (a)
A3/A-		$	824	million
Baa2/BBB		$	993	million
Bal/BB+		$	2,010	million

(a) The change between rating categories is incremental, not cumulative.

Additionally, if The Bank of New York Mellon’s debt rating had fallen below investment grade on March 31, 2013, existing collateral arrangements would have required us to have posted an additional $576 million of collateral.

Offsetting assets and liabilities

The following tables present derivative instruments and financial instruments that are either subject to an enforceable netting agreement or offset by collateral arrangements. There were no derivative instruments or financial instruments subject to a netting agreement for which we are not currently netting.

Note 18 - Commitments and contingent liabilities

In the normal course of business, various commitments and contingent liabilities are outstanding that are not reflected in the accompanying consolidated balance sheets.

Our significant trading and off-balance sheet risks are securities, foreign currency and interest rate risk management products, commercial lending commitments, letters of credit and securities lending indemnifications. We assume these risks to reduce

interest rate and foreign currency risks, to provide customers with the ability to meet credit and liquidity needs and to hedge foreign currency and interest rate risks. These items involve, to varying degrees, credit, foreign currency and interest rate risk not recognized in the balance sheet. Our off-balance sheet risks are managed and monitored in manners similar to those used for on-balance sheet risks. Significant industry concentrations related to credit exposure at March 31, 2013 are disclosed in the financial institutions portfolio exposure table and the commercial portfolio exposure table below.

Major concentrations in securities lending are primarily to broker-dealers and are generally collateralized with cash. Securities lending transactions are discussed below.

The following table presents a summary of our off-balance sheet credit risks, net of participations.

Off-balance sheet credit risks	March 31,		Dec. 31,
(in millions)	2013		2012
Lending commitments (a)	$	31,522	$	31,265
Standby letters of credit (b)	7,129		7,167
Commercial letters of credit	156		219
Securities lending indemnifications	251,977		245,717

(a) Net of participations totaling $612 million at March 31, 2013 and $350 million at Dec. 31, 2012.

(b) Net of participations totaling $1.0 billion at March 31, 2013 and $1.0 billion at Dec. 31, 2012.

Included in lending commitments are facilities that provide liquidity for variable rate tax-exempt securities wrapped by monoline insurers. The credit approval for these facilities is based on an assessment of the underlying tax-exempt issuer and considers factors other than the financial strength of the monoline insurer.

The total potential loss on undrawn lending commitments, standby and commercial letters of credit, and securities lending indemnifications is equal to the total notional amount if drawn upon, which does not consider the value of any collateral.

Since many of the commitments are expected to expire without being drawn upon, the total amount does not necessarily represent future cash requirements. A summary of lending commitment maturities is as follows: $9.2 billion in less than one year, $21.9 billion in one to five years and $0.4 billion over five years.

Standby letters of credit (“SBLC”) principally support corporate obligations. As shown in the off-balance sheet credit risks table, the maximum potential exposure of SBLCs was $7.1 billion at March 31, 2013 and $7.2 billion at Dec. 31, 2012, and includes $677 million and $781 million that were collateralized with cash and securities at March 31, 2013 and Dec. 31, 2012, respectively. At March 31, 2013, $3.9 billion of the SBLCs will expire within one year and $3.2 billion in one to five years.

We must recognize, at the inception of standby letters of credit and foreign and other guarantees, a liability for the fair value of the obligation undertaken in issuing the guarantee. As required by ASC 460 - Guarantees, the fair value of the liability, which was recorded with a corresponding asset in other assets, was estimated as the present value of contractual customer fees.

The estimated liability for losses related to these commitments and SBLCs, if any, is included in the allowance for lending-related commitments. The allowance for lending-related commitments was $121 million at March 31, 2013 and $121 million at Dec. 31, 2012.

Payment/performance risk of SBLCs is monitored using both historical performance and internal ratings criteria. BNY Mellon’s historical experience is that SBLCs typically expire without being funded. SBLCs below investment grade are monitored closely for payment/performance risk. The table below shows SBLCs by investment grade:

Standby letters of credit	March 31,		Dec. 31,
	2013		2012
Investment grade	91	%	93	%
Noninvestment grade	9	%	7	%

A commercial letter of credit is normally a short-term instrument used to finance a commercial contract for the shipment of goods from a seller to a

103 BNY Mellon

Notes to Consolidated Financial Statements(continued)

buyer. Although the commercial letter of credit is contingent upon the satisfaction of specified conditions, it represents a credit exposure if the buyer defaults on the underlying transaction. As a result, the total contractual amounts do not necessarily represent future cash requirements. Commercial letters of credit totaled $156 million at March 31, 2013 compared with $219 million at Dec. 31, 2012.

A securities lending transaction is a fully collateralized transaction in which the owner of a security agrees to lend the security (typically through an agent, in our case, The Bank of New York Mellon), to a borrower, usually a broker-dealer or bank, on an open, overnight or term basis, under the terms of a prearranged contract, which normally matures in less than 90 days.

We typically lend securities with indemnification against borrower default. We generally require the borrower to provide cash collateral with a value of 102% of the fair value of the securities borrowed, which is monitored on a daily basis, thus reducing credit risk. Market risk can also arise in securities lending transactions. These risks are controlled through policies limiting the level of risk that can be undertaken. Securities lending transactions are generally entered into only with highly rated counterparties. Securities lending indemnifications were secured by collateral of $259 billion at March 31, 2013 and $253 billion at Dec. 31, 2012.

We expect many of these guarantees to expire without the need to advance any cash. The revenue associated with guarantees frequently depends on the credit rating of the obligor and the structure of the transaction, including collateral, if any.

Exposure for certain administrative errors

In connection with certain funds that we manage, we may be liable to the funds for certain administrative errors. The errors relate to questions about the resident status of certain offshore tax exempt funds, potentially exposing the Company to a tax liability related to the funds’ earnings. The Company is in discussions with tax authorities regarding the funds. In addition to amounts accrued, we believe it is reasonably possible that we could have a potential additional exposure of up to $175 million.

Indemnification Arrangements

We have provided standard representations for underwriting agreements, acquisition and divestiture agreements, sales of loans and commitments, and other similar types of arrangements and customary indemnification for claims and legal proceedingsrelated to providing financial services that are not otherwise included above. Insurance has been purchased to mitigate certain of these risks. Generally, there are no stated or notional amounts included in these indemnifications and the contingencies triggering the obligation for indemnification are not expected to occur. Furthermore, often counterparties to these transactions provide us with comparable indemnifications. We are unable to develop an estimate of the maximum payout under these indemnifications for several reasons. In addition to the lack of a stated or notional amount in a majority of such indemnifications, we are unable to predict the nature of events that would trigger indemnification or the level of indemnification for a certain event. We believe, however, that the possibility that we will have to make any material payments for these indemnifications is remote. At March 31, 2013 and Dec. 31, 2012, we had no material liabilities under these arrangements.

Clearing and Settlement Exchanges

We are a minority equity investor in, and member of, several industry clearing or settlement exchanges through which foreign exchange, securities, or other transactions settle. Certain of these industry clearing and settlement exchanges require their members to guarantee their obligations and liabilities or to provide financial support in the event other members do not honor their obligations. We believe the likelihood that a clearing or settlement exchange (of which we are a member) would become insolvent is remote. Additionally, certain settlement exchanges have implemented loss allocation policies that enable the exchange to allocate settlement losses to the members of the exchange. It is not possible to quantify such mark-to-market loss until the loss occurs. In addition, any ancillary costs that occur as a result of any mark-to-market loss cannot be quantified. At March 31, 2013 and Dec. 31, 2012, we have not recorded any material liabilities under these arrangements.

BNY Mellon 104

Notes to Consolidated Financial Statements(continued)

Legal proceedings

In the ordinary course of business, BNY Mellon and its subsidiaries are routinely named as defendants in or made parties to pending and potential legal actions and regulatory matters. Claims for significant monetary damages are often asserted in many of these legal actions, while claims for disgorgement, penalties and/or other remedial sanctions may be sought in regulatory matters. It is inherently difficult to predict the eventual outcomes of such matters given their complexity and the particular facts and circumstances at issue in each of these matters. However, on the basis of our current knowledge and understanding, we do not believe that judgments or settlements, if any, arising from these matters (either individually or in the aggregate, after giving effect to applicable reserves and insurance coverage) will have a material adverse effect on the consolidated financial position or liquidity of BNY Mellon, although they could have a material effect on net income in a given period.

In view of the inherent unpredictability of outcomes in litigation and regulatory matters, particularly where (i) the damages sought are substantial or indeterminate, (ii) the proceedings are in the early stages, or (iii) the matters involve novel legal theories or a large number of parties, as a matter of course there is considerable uncertainty surrounding the timing or ultimate resolution of litigation and regulatory matters, including a possible eventual loss, fine, penalty or business impact, if any, associated with each such matter. In accordance with applicable accounting guidance, BNY Mellon establishes accruals for litigation and regulatory matters when those matters proceed to a stage where they present loss contingencies that are both probable and reasonably estimable. In such cases, there may be a possible exposure to loss in excess of any amounts accrued. BNY Mellon will continue to monitor such matters for developments that could affect the amount of the accrual, and will adjust the accrual amount as appropriate. If the loss contingency in question is not both probable and reasonably estimable, BNY Mellon does not establish an accrual and the matter will continue to be monitored for any developments that would make the loss contingency both probable and reasonably estimable. BNY Mellon believes that its accruals for legal proceedings are appropriate and, in the aggregate, are not material to the consolidated financial position of BNY Mellon, although future

accruals could have a material effect on net income in a given period.

For certain of those matters described herein for which a loss contingency may, in the future, be reasonably possible (whether in excess of a related accrued liability or where there is no accrued liability), BNY Mellon is currently unable to estimate a range of reasonably possible loss. For those matters where BNY Mellon is able to estimate a reasonably possible loss, exclusive of matters described in Note 11 of the Notes to Consolidated Financial Statements, subject to the accounting and reporting requirements of ASC 740 (FASB Interpretation 48), the aggregate range of such reasonably possible loss is up to $470 million in excess of the accrued liability (if any) related to those matters.

The following describes certain judicial, regulatory and arbitration proceedings involving BNY Mellon:

Sentinel Matters

As previously disclosed, on Jan. 18, 2008, The Bank of New York Mellon filed a proof of claim in the Chapter 11 bankruptcy proceeding of Sentinel Management Group, Inc. (“Sentinel”) pending in federal court in the Northern District of Illinois, seeking to recover approximately $312 million loaned to Sentinel and secured by securities and cash in an account maintained by Sentinel at The Bank of New York Mellon. On March 3, 2008, the bankruptcy trustee filed an adversary complaint against The Bank of New York Mellon seeking to disallow The Bank of New York Mellon’s claim and seeking damages for allegedly aiding and abetting Sentinel insiders in misappropriating customer assets and improperly using those assets as collateral for the loan. In a decision dated Nov. 3, 2010, the court found for The Bank of New York Mellon and against the bankruptcy trustee, holding that The Bank of New York Mellon’s loan to Sentinel is valid, fully secured and not subject to equitable subordination. The bankruptcy trustee appealed this decision, and on August 9, 2012, the United States Court of Appeals for the Seventh Circuit issued a decision affirming the trial court’s judgment. On September 7, 2012, the bankruptcy trustee filed a petition for rehearing on the fraudulent transfer portion of the opinion and, on November 30, 2012, the Court of Appeals withdrew its opinion and vacated its judgment. The appeal remains under consideration.

105 BNY Mellon

Notes to Consolidated Financial Statements(continued)

As previously disclosed, in November 2009, the Division of Enforcement of the U.S. Commodities Futures Trading Commission (“CFTC”) indicated that it is considering a recommendation to the CFTC that it file a civil enforcement action against The Bank of New York Mellon for possible violations of the Commodity Exchange Act and CFTC regulations in connection with its relationship to Sentinel. The Bank of New York Mellon responded in writing to the CFTC on Jan. 29, 2010 and provided an explanation as to why an enforcement action is unwarranted.

Securities Lending Matters

As previously disclosed, BNY Mellon or its affiliates have been named as defendants in a number of lawsuits initiated by participants in BNY Mellon’s securities lending program, which is a part of BNY Mellon’s Investment Services business. The lawsuits were filed on various dates from 2009 to 2013,and are currently pending in courts in New York, South Carolina, North Carolina and Illinois and in commercial court in London. The complaints assert contractual, statutory, and common law claims, including claims for negligence and breach of fiduciary duty. The plaintiffs allege losses in connection with the investment of securities lending collateral, including losses related to investments in Sigma Finance Inc. (“Sigma”), Lehman Brothers Holdings, Inc. and certain asset-backed securities, and seek damages as to those losses.

Matters Relating To Bernard L. Madoff

As previously disclosed, on May 11, 2010, the New York State Attorney General commenced a civil lawsuit against Ivy Asset Management LLC (“Ivy”), a subsidiary of BNY Mellon that manages primarily funds-of-hedge-funds, and two of its former officers in New York state court. The lawsuit alleges that Ivy, in connection with its role as sub-advisor to investment managers whose clients invested with Madoff, did not disclose certain material facts about Madoff. The complaint seeks an accounting of compensation received from January 1997 to the present by the Ivy defendants in connection with the Madoff investments, and unspecified damages, including restitution, disgorgement, costs and attorneys’ fees.

As previously disclosed, on Oct. 21, 2010, the U.S. Department of Labor commenced a civil lawsuit against Ivy, two of its former officers, and others in federal court in the Southern District of New York.

The lawsuit alleges that Ivy violated the Employee Retirement Income Security Act (“ERISA”) by failing to disclose certain material facts about Madoff to investment managers subadvised by Ivy whose clients included employee benefit plan investors. The complaint seeks disgorgement and damages.

As previously disclosed, Ivy or its affiliates have been named in a number of civil lawsuits filed beginning Jan. 27, 2009 relating to certain investment funds that allege losses due to the Madoff investments. Ivy acted as a sub-advisor to the investment managers of some of those funds. Plaintiffs assert various causes of action including securities and common-law fraud. Certain of the cases have been certified as class actions and/or assert derivative claims on behalf of the funds. Most of the cases have been consolidated in two actions in federal court in the Southern District of New York, with certain cases filed in New York State Supreme Court for New York and Nassau counties.

On Nov. 13, 2012, Ivy entered into a settlement agreement with the New York State Attorney General, the U.S. Department of Labor, and the civil lawsuit plaintiffs that would settle all claims for $210 million. The settlement is subject to judicial approval, which the various courts have preliminarily given. A hearing on final approval was held March 15, 2013; we await the Court’s ruling.

On Dec. 8, 2010, the Trustee overseeing the Madoff liquidation sued many of the same defendants in bankruptcy court in New York, seeking to avoid withdrawals from Madoff investments made by various funds-of-funds (including six funds-of-funds managed by Ivy). On Oct. 12, 2012, Ivy and the Trustee entered into a written settlement agreement, agreeing to settle all claims for $2 million. The settlement was approved by the Bankruptcy Court on Dec. 4, 2012.

Medical Capital Litigations

As previously disclosed, The Bank of New York Mellon has been named as a defendant in a number of class actions and non-class actions brought by numerous plaintiffs in connection with its role as indenture trustee for debt issued by affiliates of Medical Capital Corporation. The actions, filed in late 2009 and currently pending in federal court in the Central District of California, allege that The Bank of New York Mellon breached its fiduciary and

BNY Mellon 106

Notes to Consolidated Financial Statements(continued)

contractual obligations to the holders of the underlying securities, and seek unspecified damages.

On Dec. 21, 2012, The Bank of New York Mellon entered into a settlement agreement with the plaintiffs and the Federal Equity Receiver for Medical Capital Corporation and its affiliates. Under the terms of the settlement, The Bank of New York Mellon will make a payment of $114 million in exchange for a complete release of claims. The settlement was preliminarily approved on Feb. 28, 2013.

Foreign Exchange Matters

As previously disclosed, beginning in December 2009, government authorities have been conducting inquiries seeking information relating primarily to standing instruction foreign exchange transactions in connection with custody services BNY Mellon provides to public pension plans and certain other custody clients. BNY Mellon is cooperating with these inquiries.

In addition, in early 2011, as previously disclosed, the Virginia Attorney General’s Office and the Florida Attorney General’s Office each intervened in a qui tam lawsuit pending in its jurisdiction, and, on Aug. 11, 2011, filed superseding complaints. On Nov. 9, 2012, the Virginia court, which had previously dismissed all of the claims against BNY Mellon, dismissed the lawsuit with prejudice by agreement of the parties. On Oct. 4, 2011, the New York Attorney General’s Office, the New York City Comptroller and various city pension and benefit funds filed a lawsuit asserting, claims under the Martin Act and state and city false claims acts. Also, on Oct. 4, 2011, the United States Department of Justice (“DOJ”) filed a civil lawsuit seeking civil penalties under 12 U.S.C. Section 1833a and injunctive relief under 18 U.S.C. Section 1345 based on alleged ongoing violations of 18 U.S.C. Sections 1341 and 1343 (mail and wire fraud). On Jan. 17, 2012, the court approved a partial settlement resolving the DOJ’s claim for injunctive relief. In October 2011, several political subdivisions of the state of California intervened in a qui tam lawsuit that was removed to federal district court in California. On March 30, 2012, the court dismissed certain of plaintiffs’ claims, including all claims under the California False Claims Act. Certain plaintiffs have since filed an amended complaint. Several plaintiffs also had their claims dismissed for improper venue and one refiled on Sept. 5, 2012 in a

different California federal district court. On Oct. 26, 2011, the Massachusetts Securities Division filed an Administrative Complaint against BNY Mellon.

BNY Mellon has also been named as a defendant in several putative class action federal lawsuits filed on various dates in 2011 and 2012. The complaints, which assert claims including breach of contract and ERISA violations, all allege that the prices BNY Mellon charged for standing instruction foreign exchange transactions executed in connection with custody services provided by BNY Mellon were improper. In addition, BNY Mellon has been named as a nominal defendant in several derivative lawsuits filed 2011 and 2012 in state and federal court in New York. BNY Mellon has also been named in a qui tam lawsuit filed on May 22, 2012 in Massachusetts state court. To the extent these lawsuits are pending in federal court, they have been consolidated for pre-trial purposes in federal court in New York.

Lyondell Litigation

As previously disclosed, in an action filed in New York State Supreme Court for New York County, on Sept. 14, 2010, plaintiffs as holders of debt issued by Basell AF in 2005 allege that The Bank of New York Mellon, as indenture trustee, breached its contractual and fiduciary obligations by executing an intercreditor agreement in 2007 in connection with Basell’s acquisition of Lyondell Chemical Company. Plaintiffs are seeking damages for their alleged losses resulting from the execution of the 2007 intercreditor agreement that allowed the company to increase the amount of its senior debt.

Tax Litigation

As previously disclosed, on Aug. 17, 2009, BNY Mellon received a Statutory Notice of Deficiency disallowing tax benefits for the 2001 and 2002 tax years in connection with a 2001 transaction that involved the payment of UK corporate income taxes that were credited against BNY Mellon’s U.S. corporate income tax liability. On Nov. 10, 2009, BNY Mellon filed a petition with the U.S. Tax Court contesting the disallowance of the benefits. Trial was held from April 16 to May 17, 2012. On Feb. 11, 2013, the Tax Court upheld the IRS’s Notice of Deficiency and disallowed BNY Mellon’s tax credits and associated transaction costs.  BNY Mellon will appeal the Tax Court’s ruling. See Note 11 of the Notes to Consolidated Financial Statements for additional information.

Mortgage-Securitization Trusts Proceeding

As previously disclosed, The Bank of New York Mellon as trustee is the petitioner in a legal proceeding filed in New York State Supreme Court, New York County on June 29, 2011, seeking approval of a proposed settlement involving Bank of America Corporation and bondholders in certain Countrywide residential mortgage-securitization trusts. The New York and Delaware Attorneys General have intervened in this proceeding.

Note 19 - Lines of businesses

We have an internal information system that produces performance data along product and services lines for our two principal businesses and the Other segment.

Business accounting principles

Our business data has been determined on an internal management basis of accounting, rather than the generally accepted accounting principles used for consolidated financial reporting. These

measurement principles are designed so that reported results of the businesses will track their economic performance.

Business results are subject to reclassification whenever improvements are made in the measurement principles or when organizational changes are made. In the first quarter of 2013, incentive expense related to restricted stock and certain corporate overhead charges were allocated to the Investment Management and Investment Services businesses which were previous included in the Other segment. All prior periods were restated to reflect these changes. Additionally, the results of the businesses for the first quarter of 2013 reflect higher internal crediting rates for domestic deposits, which are regularly updated to reflect the value of deposit balances and distribution of overall interest revenue. There was no impact to consolidated results.

The accounting policies of the businesses are the same as those described in Note 1 of the Notes to Consolidated Financial Statements in our 2012 Annual Report.

The primary types of revenue for our two principal businesses and the Other segment are presented below:

Business	Primary types of revenue
Investment Management	Ÿ   Investment management and performance fees from: Mutual funds Institutional clients Private clients High-net-worth individuals and families, endowments and foundations and related entities Ÿ   Distribution and servicing fees
Investment Services	Ÿ   Asset servicing fees, including institutional trust and custody fees, broker-dealer services and securities lending Ÿ   Issuer services fees, including Corporate Trust and Depositary Receipts Ÿ   Clearing services fees, including broker-dealer services, registered investment advisor services and prime brokerage services Ÿ   Treasury services fees, including global payment services and working capital solutions Ÿ   Foreign exchange
Other segment	Ÿ   Credit-related activities Ÿ   Leasing operations Ÿ   Corporate treasury activities Ÿ   Global markets and institutional banking services Ÿ   Business exits

The results of our businesses are presented and analyzed on an internal management reporting basis:

• Revenue amounts reflect fee and other revenue generated by each business. Fee and other revenue transferred between businesses under

revenue transfer agreements is included within other revenue in each business.

• Revenues and expenses associated with specific client bases are included in those businesses. For example, foreign exchange activity

BNY Mellon 108

Notes to Consolidated Financial Statements(continued)

associated with clients using custody products is allocated to Investment Services.

• Net interest revenue is allocated to businesses based on the yields on the assets and liabilities generated by each business. We employ a funds transfer pricing system that matches funds with the specific assets and liabilities of each business based on their interest sensitivity and maturity characteristics.

• Support and other indirect expenses are allocated to businesses based on internally-developed methodologies.

• Recurring FDIC expense is allocated to the businesses based on average deposits generated within each business.

• Litigation expense is generally recorded in the business in which the charge occurs.

• Management of the investment securities portfolio is a shared service contained in the

Other segment. As a result, gains and losses associated with the valuation of the securities portfolio are included in the Other segment.

• Client deposits serve as the primary funding source for our investment securities portfolio. We typically allocate all interest revenue to the businesses generating the deposits. Accordingly, accretion related to the restructured investment securities portfolio has been included in the results of the businesses.

• M&I expenses and restructuring charges are corporate level items and are therefore recorded in the Other segment.

• Balance sheet assets and liabilities and their related income or expense are specifically assigned to each business. Businesses with a net liability position have been allocated assets.

• Goodwill and intangible assets are reflected within individual businesses.

The following consolidating schedules show the contribution of our businesses to our overall profitability.

Item 4. Controls and Procedures

Disclosure controls and procedures

Our management, including the Chief Executive Officer and Chief Financial Officer, with participation by the members of the Disclosure Committee, has responsibility for ensuring that there is an adequate and effective process for establishing, maintaining, and evaluating disclosure controls and procedures that are designed to ensure that information required to be disclosed by us in our SEC reports is timely recorded, processed, summarized and reported and that information required to be disclosed by BNY Mellon is accumulated and communicated to BNY Mellon’s management to allow timely decisions regarding the required disclosure. In addition, our ethics hotline can also be used by employees and others for the anonymous communication of concerns about financial controls or reporting matters. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.

As of the end of the period covered by this report, an evaluation was carried out under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective.

In our 2012 Annual Report, we stated that our disclosure controls and procedures were effective as of December 31, 2012, except for our processes and procedures for reporting AUC/A.  We subsequently filed an Amendment No. 1 on Form 10-K/A to our Annual Report on Form 10-K for the fiscal year ended December 31, 2012 stating that our disclosure controls and procedures were not effective because of our processes and procedures for reporting

AUC/A.

As we previously indicated in our 2012 Annual Report, subsequent to December 31, 2012, we

remediated our disclosure controls and procedures over the preparation of our AUC/A.  The errors relating to AUC/A are unrelated to our internal control over financial reporting.  As previously disclosed in our 2012 Annual Report, we are reviewing our process for the reporting of information included in our public filings and we have initiated plans to streamline and enhance the data collection processes and systems relating to AUC/A and other information in our public filings.  To date, the review has not resulted in any material changes to our publicly disclosed historical information.

Changes in internal control over financial reporting

In the ordinary course of business, we may routinely modify, upgrade or enhance our internal controls and procedures for financial reporting. There have not been any changes in our internal controls over financial reporting as defined in Rule 13a-15(f) of the Exchange Act during the first quarter of 2013 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

CERTIFICATION

Fair Value Disclosures [Abstract]

Fair Value Measurement

Fair value measurement

The guidance related to “Fair Value Measurement” included in ASC 820 defines fair value as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date and establishes a framework for measuring fair value. It establishes a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date and expands the disclosures about instruments measured at fair value. ASC 820 requires consideration of a company’s own creditworthiness when valuing liabilities.

The standard provides a consistent definition of fair value, which focuses on exit price in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The objective is to determine from weighted indicators of fair value a reasonable point within the range that is most representative of fair value under current market conditions.

Determination of fair value

Following is a description of our valuation methodologies for assets and liabilities measured at fair value. We have established processes for determining fair values. Fair value is based upon quoted market prices in active markets, where available. For financial instruments where quotes from recent exchange transactions are not available, we determine fair value based on discounted cash flow analysis, comparison to similar instruments, and the use of financial models. Discounted cash flow analysis is dependent upon estimated future cash flows and the level of interest rates. Model-based pricing uses inputs of observable prices, where available, for interest rates, foreign exchange rates, option volatilities and other factors. Models are benchmarked and validated by an independent internal risk management function. Our valuation process takes into consideration factors such as counterparty credit quality, liquidity, concentration concerns, and observability of model parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value.

Most derivative contracts are valued using internally developed models which are calibrated to observable market data and employ standard market pricing theory for their valuations. An initial “risk-neutral” valuation is performed on each position assuming time-discounting based on a AA credit curve. Then, to arrive at a fair value that incorporates counter-party credit risk, a credit adjustment is made to these results by discounting each trade’s expected exposures to the counterparty using the counterparty’s credit spreads, as implied by the credit default swap market. We also adjust expected liabilities to the counterparty using BNY Mellon’sown credit spreads, as implied by the credit default swap market. Accordingly, the valuation of our derivative position is sensitive to the current changes in our own credit spreads as well as those of our counterparties.

In certain cases, recent prices may not be observable for instruments that trade in inactive or less active markets. Upon evaluating the uncertainty in valuing financial instruments subject to liquidity issues, we make an adjustment to their value. The determination of the liquidity adjustment includes the availability of external quotes, the time since the latest available quote and the price volatility of the instrument.

Certain parameters in some financial models are not directly observable and, therefore, are based on management’s estimates and judgments. These financial instruments are normally traded less actively. We apply valuation adjustments to mitigate the possibility of error and revision in the model based estimate value. Examples include products where parameters such as correlation and recovery rates are unobservable.

The methods described above for instruments that trade in inactive or less active markets may produce a current fair value calculation that may not be indicative of net realizable value or reflective of future fair values. We believe our methods of determining fair value are appropriate and consistent with other market participants. However, the use of different methodologies or different assumptions to value certain financial instruments could result in a different estimate of fair value.

Valuation hierarchy

ASC 820 established a three-level valuation hierarchy for disclosure of fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are described below.

Level 1: Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 1 assets and liabilities include debt and equity securities and derivative financial instruments actively traded on exchanges and U.S. Treasury securities that are actively traded in highly liquid over-the-counter markets.

Level 2: Observable inputs other than Level 1 prices, for example, quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs that are observable or can be corroborated, either directly or indirectly, for substantially the full term of the financial instrument. Level 2 assets and liabilities include debt instruments that are traded less frequently than exchange-traded securities and derivative instruments whose model inputs are observable in the market or can be corroborated by market-observable data. Examples in this category are agency and non-agency mortgage-backed securities, corporate debt securities and over-the-counter derivative contracts.

Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement. Examples in this category include certain private equity investments, derivative contracts that are highly structured or long-dated, and interests in certain securitized financial assets.

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

Following is a description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy.

Securities

Where quoted prices are available in an active market, we classify the securities within Level 1 of the valuation hierarchy. Securities include both long and short positions. Level 1 securities include highly liquid government bonds, money market mutual funds and exchange-traded equities.

If quoted market prices are not available, we estimate fair values using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. Examples of such instruments, which would generally be classified within Level 2 of the valuation hierarchy, include agency and non-agency mortgage-backed securities, commercial mortgage-backed securities, sovereign debt, corporate bonds and foreign covered bonds.

For securities where quotes from recent transactions are not available for identical securities, wedetermine fair value primarily based on pricing sources with reasonable levels of price transparency that employ financial models or obtain comparison to similar instruments to arrive at “consensus” prices.

Specifically, the pricing sources obtain recent transactions for similar types of securities (e.g., vintage, position in the securitization structure) and ascertain variables such as discount rate and speed of prepayment for the types of transaction and apply such variables to similar types of bonds. We view these as observable transactions in the current marketplace and classify such securities as Level 2. Pricing sources discontinue pricing any specific security whenever they determine there is insufficient observable data to provide a good faith opinion on price.

In addition, we have significant investments in more actively traded agency RMBS and other types of securities such as sovereign debt. The pricing sources derive the prices for these securities largely from quotes they obtain from three major inter-dealer brokers. The pricing sources receive their daily observed trade price and other information feeds from the inter-dealer brokers.

For securities with bond insurance, the financial strength of the insurance provider is analyzed and that information is included in the fair value assessment for such securities.

In certain cases where there is limited activity or less transparency around inputs to the valuation, we classify those securities in Level 3 of the valuation hierarchy. Securities classified within Level 3 primarily include securities of state and political subdivisions and distressed debt securities.

At March 31, 2013, more than 99% of our securities were valued by pricing sources with reasonable levels of price transparency. Less than 1% of our securities were priced based on economic models and non-binding dealer quotes, and are included in Level 3 of the ASC 820 hierarchy.

Consolidated collateralized loan obligations

BNY Mellon values assets in consolidated CLOs using observable market prices observed from the secondary loan market. The returns to the note holders are solely dependent on the assets and accordingly equal the value of those assets. Based on the structure of the CLOs, the valuation of the assets is attributable to the senior note holders. Changes in the values of assets and liabilities are reflected in the income statement as investment income and interest of investment management fund note holders, respectively.

Derivatives

We classify exchange-traded derivatives valued using quoted prices in Level 1 of the valuation hierarchy. Examples include exchanged-traded equity and foreign exchange options. Since few other classes of derivative contracts are listed on an exchange, most of our derivative positions are valued using internally developed models that use as their basis readily observable market parameters, and we classify them in Level 2 of the valuation hierarchy. Such derivatives include basic swaps and options and credit default swaps.

Derivatives valued using models with significant unobservable market parameters in markets that lack two-way flow are classified in Level 3 of the valuation hierarchy. Examples include long-dated interest rate or currency swaps and options, where parameters may be unobservable for longer maturities; and certain products, where correlation risk is unobservable. The fair value of these derivatives compose less than 1% of our derivative financial instruments. Additional disclosures of derivative instruments are provided in Note 17 of the Notes to Consolidated Financial Statements.

Loans and unfunded lending-related commitments

Where quoted market prices are not available, we generally base the fair value of loans and unfunded lending-related commitments on observable market prices of similar instruments, including bonds, credit derivatives and loans with similar characteristics. If observable market prices are not available, we base the fair value on estimated cash flows adjusted for credit risk which are discounted using an interest rate appropriate for the maturity of the applicable loans or the unfunded lending-related commitments.

Unrealized gains and losses, if any, on unfunded lending-related commitments carried at fair value are classified in Other assets and Other liabilities, respectively. Loans and unfunded lending-related commitments carried at fair value are generally classified within Level 2 of the valuation hierarchy.

Seed capital

In our Investment Management business, we manage investment assets, including equities, fixed income, money market and alternative investment funds for institutions and other investors. As part of that activity, we make seed capital investments in certain funds. Seed capital is included in other assets. When applicable, we value seed capital based on the published NAV of the fund. We include funds in which ownership interests in the fund are publicly traded in an active market and institutional funds in which investors trade in and out daily in Level 1 of the valuation hierarchy. We include open-end funds where investors are allowed to sell their ownership interest back to the fund less frequently than daily and where our interest in the fund contains no other rights or obligations in Level 2 of the valuation hierarchy. However, we generally include investments in funds that allow investors to sell their ownership interest back to the fund less frequently than monthly in Level 3, unless actual redemption prices are observable.

For other types of investments in funds, we consider all of the rights and obligations inherent in our ownership interest, including the reported NAV as well as other factors that affect the fair value of our interest in the fund. To the extent the NAV measurements reported for the investments are based on unobservable inputs or include other rights and obligations (e.g., obligation to meet cash calls), we generally classify them in Level 3 of the valuation hierarchy.

Certain interests in securitizations

For certain interests in securitizations that are classified in securities available-for-sale, trading assets and long-term debt, we use discounted cash flow models, which generally include assumptions of projected finance charges related to the securitized assets, estimated net credit losses, prepayment assumptions and estimates of payments to third-party investors. When available, we compare our fair value estimates and assumptions to market activity and to the actual results of the securitized portfolio.

Private equity investments

Our Other segment includes holdings of nonpublic private equity investment through funds managed by third-party investment managers. We value private equity investments initially based upon the transaction price, which we subsequently adjust to reflect expected exit values as evidenced by financing and sale transactions with third parties or through ongoing reviews by the investment managers.

Private equity investments also include publicly held equity investments, generally obtained through the initial public offering of privately held equity investments. These equity investments are often held in a partnership structure. Publicly held investments are marked-to-market at the quoted public value less adjustments for regulatory or contractual sales restrictions or adjustments to reflect the difficulty in selling a partnership interest.

Discounts for restrictions are quantified by analyzing the length of the restriction period and the volatility of the equity security. Publicly held private equity investments are primarily classified in Level 2 of the valuation hierarchy.

The following tables present the financial instruments carried at fair value at March 31, 2013 and Dec. 31 2012, by caption on the consolidated balance sheet and by ASC 820 valuation hierarchy (as described above). We have included credit ratings information in certain of the tables because the information indicates the degree of credit risk to which we are exposed, and significant changes in ratings classifications could result in increased risk for us. There were no material transfers between Level 1 and Level 2 during the first quarter of 2013.

Changes in Level 3 fair value measurements

Our classification of a financial instrument in Level 3 of the valuation hierarchy is based on the significance of the unobservable factors to the overall fair value measurement. However, these instruments generally include other observable components that are actively quoted or validated to third-party sources; accordingly, the gains and losses in the table below include changes in fair value due to observable parameters as well as the unobservable parameters in our valuation methodologies. We also frequently manage the risks of Level 3 financial instruments using securities and derivatives positions that are Level 1 or 2 instruments which are not included in the table; accordingly, the gains or losses below do not reflect the effect of our risk management activities related to the Level 3 instruments.

The Company has a Level 3 Pricing Committee which evaluates the valuation techniques used in determining the fair value of Level 3 assets and liabilities.

The tables below include a roll forward of the balance sheet amounts for the quarter ended March 31, 2013 and 2012 (including the change in fair value), for financial instruments classified in Level 3 of the valuation hierarchy.

Assets and liabilities measured at fair value on a nonrecurring basis

Under certain circumstances, we make adjustments to fair value our assets, liabilities and unfunded lending-related commitments although they are not measured at fair value on an ongoing basis. An example would be the recording of an impairment of an asset.

The following table presents the financial instruments carried on the consolidated balance sheet by caption and by level in the fair value hierarchy as of March 31, 2013 and Dec. 31, 2012, for which a nonrecurring change in fair value has been recorded during the quarters ended March 31, 2013 and Dec. 31, 2012.

Estimated fair value of financial instruments

The carrying amounts of our financial instruments (i.e., monetary assets and liabilities) are determined under different accounting methods - see Note 1 of the Notes to Consolidated Financial Statements in our 2012 Annual Report. The following disclosure discusses these instruments on a uniform fair value basis. However, active markets do not exist for a significant portion of these instruments. For financial instruments where quoted prices from identical assets and liabilities in active markets do not exist, we determine fair value based on discounted cash flow analysis and comparison to similar instruments. Discounted cash flow analysis is dependent upon estimated future cash flows and the level of interest rates. Other judgments would result in different fair values. The assumptions we used at March 31, 2013 and Dec. 31, 2012 include discount rates ranging principally from 0.20% to 4.87%. The fair value information supplements the basic financial statements and other traditional financial data presented throughout this report.

A summary of the practices used for determining fair value and the respective level in the valuation hierarchy for financial assets and liabilities not recorded at fair value follows.

Interest-bearing deposits with the Federal Reserve and other central banks and interest-bearing deposits with banks

The estimated fair value of interest-bearing deposits with the Federal Reserve and other central banks is equal to the book value as these interest-bearing deposits are generally considered cash equivalents. These instruments are classified as Level 2 within the valuation hierarchy. The estimated fair value of interest-bearing deposits with banks is generally determined using discounted cash flows and duration of the instrument to maturity. The primary inputs used to value these transactions are interest rates based on current LIBOR market rates and time to maturity. Interest-bearing deposits with banks are classified as Level 2 within the valuation hierarchy.

Federal funds sold and securities purchased under resale agreements

The estimated fair value of federal funds sold and securities purchased under resale agreements is based on inputs such as interest rates and tenors. Federal funds sold and securities purchased under resale agreements are classified as Level 2 within the valuation hierarchy.

Securities held-to-maturity

Where quoted prices are available in an active market for identical assets and liabilities, we classify the securities as Level 1 within the valuation hierarchy. Securities are defined as both long and short positions. Level 1 securities include U.S. Treasury securities.

If quoted market prices are not available for identical assets and liabilities, we estimate fair value using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. Examples of such instruments, which would generally be classified as Level 2 within the valuation hierarchy, include certain agency and non-agency mortgage-backed securities, commercial mortgage-backed securities and state and political subdivision securities. For securities where quotes from active markets are not available for identical securities, we determine fair value primarily based on pricing sources with reasonable levels of price transparency that employ financial models or obtain comparison to similar instruments to arrive at “consensus” prices.

Specifically, the pricing sources obtain active market prices for similar types of securities (e.g., vintage, position in the securitization structure) and ascertain variables such as discount rate and speed of prepayment for the types of transaction and apply such variables to similar types of bonds. We view these as observable transactions in the current marketplace and classify such securities as Level 2 within the valuation hierarchy.

Loans

For residential mortgage loans, fair value is estimated using discounted cash flow analysis, adjusting where appropriate for prepayment estimates, using interest rates currently being offered for loans with similar terms and maturities to borrowers. The estimated fair value of margin loans and overdrafts is equal to the book value due to the short-term nature of these assets. The estimated fair value of other types of loans is determined using discounted cash flows. Inputs include current LIBOR market rates adjusted for credit spreads. These loans are generally classified as Level 2 within the valuation hierarchy.

Other financial assets

Other financial assets include cash, the Federal Reserve Bank stock and accrued interest receivable. Cash is classified as Level 1 within the valuation hierarchy. The Federal Reserve Bank stock is not redeemable or transferable. The estimated fair value of the Federal Reserve Bank stock is based on the issue price and is classified as Level 2 within the valuation hierarchy. Accrued interest receivable is generally short-term. As a result, book value is considered to equal fair value. Accrued interest receivable is included as Level 2 within the valuation hierarchy.

Noninterest-bearing and interest-bearing deposits

Interest-bearing deposits are comprised of money market rate and demand deposits, savings deposits and time deposits. Except for time deposits, book value is considered to equal fair value for these deposits due to their short duration to maturity or payable on demand feature. The fair value of interest-bearing time deposits is determined using discounted cash flow analysis. Inputs primarily consist of current LIBOR market rates and time to maturity. For all noninterest-bearing deposits, book value is considered to equal fair value as a result of the short duration of the deposit. Interest-bearing and noninterest-bearing deposits are classified as Level 2 within the valuation hierarchy.

Federal funds purchased and securities sold under repurchase agreements

The estimated fair value of federal funds purchased and securities sold under repurchase agreements is based on inputs such as interest rates and tenors. Federal funds purchased and securities sold under repurchase agreements are classified as Level 2 within the valuation hierarchy.

Payables to customers and broker-dealers

The estimated fair value of payables to customers and broker-dealers is equal to the book value, due to the demand feature of the payables to customers and broker-dealers, and are classified as Level 2 within the valuation hierarchy.

Borrowings

Borrowings primarily consist of overdrafts of subcustodian account balances in our Investment Services businesses, commercial paper and accrued interest payable. The estimated fair value of overdrafts of subcustodian account balances in our Investment Services businesses is considered to equal book value as a result of the short duration of the overdrafts. Overdrafts are typically repaid within two days. The estimated fair value of our commercial paper is based on discount and duration of the commercial paper. Our commercial paper matures within 397 days from date of issue and is not redeemable prior to maturity or subject to voluntary prepayment. Our commercial paper is included in Level 2 of the valuation hierarchy. Accrued interest payable is generally short-term. As a result, book value is considered to equal fair value. Accrued interest payable is included as Level 2 within the valuation hierarchy.

Long-term debt

The estimated fair value of long-term debt is based on current rates for instruments of the same remaining maturity or quoted market prices for the same or similar issues. Long-term debt is classified as Level 2 within the valuation hierarchy.

The following table presents the estimated fair value and the carrying amount of financial instruments not carried at fair value on the consolidated balance sheet at March 31, 2013 and Dec. 31, 2012, by caption on the consolidated balance sheet and by ASC 820 valuation hierarchy (as described above).

Segment Reporting [Abstract]

Lines of Businesses

Lines of businesses

We have an internal information system that produces performance data along product and services lines for our two principal businesses and the Other segment.

Business accounting principles

Our business data has been determined on an internal management basis of accounting, rather than the generally accepted accounting principles used for consolidated financial reporting. These measurement principles are designed so that reported results of the businesses will track their economic performance.

Business results are subject to reclassification whenever improvements are made in the measurement principles or when organizational changes are made. In the first quarter of 2013, incentive expense related to restricted stock and certain corporate overhead charges were allocated to the Investment Management and Investment Services businesses which were previous included in the Other segment. All prior periods were restated to reflect these changes. Additionally, the results of the businesses for the first quarter of 2013 reflect higher internal crediting rates for domestic deposits, which are regularly updated to reflect the value of deposit balances and distribution of overall interest revenue. There was no impact to consolidated results.

The accounting policies of the businesses are the same as those described in Note 1 of the Notes to Consolidated Financial Statements in our 2012 Annual Report.

The primary types of revenue for our two principal businesses and the Other segment are presented below:

Business	Primary types of revenue
Investment Management	Ÿ   Investment management and performance fees from: Mutual funds Institutional clients Private clients High-net-worth individuals and families, endowments and foundations and related entities Ÿ   Distribution and servicing fees
Investment Services	Ÿ   Asset servicing fees, including institutional trust and custody fees, broker-dealer services and securities lending Ÿ   Issuer services fees, including Corporate Trust and Depositary Receipts Ÿ   Clearing services fees, including broker-dealer services, registered investment advisor services and prime brokerage services Ÿ   Treasury services fees, including global payment services and working capital solutions Ÿ   Foreign exchange
Other segment	Ÿ   Credit-related activities Ÿ   Leasing operations Ÿ   Corporate treasury activities Ÿ   Global markets and institutional banking services Ÿ   Business exits

The results of our businesses are presented and analyzed on an internal management reporting basis:

• Revenue amounts reflect fee and other revenue generated by each business. Fee and other revenue transferred between businesses under revenue transfer agreements is included within other revenue in each business.

• Revenues and expenses associated with specific client bases are included in those businesses. For example, foreign exchange activity associated with clients using custody products is allocated to Investment Services.

• Net interest revenue is allocated to businesses based on the yields on the assets and liabilities generated by each business. We employ a funds transfer pricing system that matches funds with the specific assets and liabilities of each business based on their interest sensitivity and maturity characteristics.

• Support and other indirect expenses are allocated to businesses based on internally-developed methodologies.

• Recurring FDIC expense is allocated to the businesses based on average deposits generated within each business.

• Litigation expense is generally recorded in the business in which the charge occurs.

• Management of the investment securities portfolio is a shared service contained in the Other segment. As a result, gains and losses associated with the valuation of the securities portfolio are included in the Other segment.

• Client deposits serve as the primary funding source for our investment securities portfolio. We typically allocate all interest revenue to the businesses generating the deposits. Accordingly, accretion related to the restructured investment securities portfolio has been included in the results of the businesses.

• M&I expenses and restructuring charges are corporate level items and are therefore recorded in the Other segment.

• Balance sheet assets and liabilities and their related income or expense are specifically assigned to each business. Businesses with a net liability position have been allocated assets.

• Goodwill and intangible assets are reflected within individual businesses.

The following consolidating schedules show the contribution of our businesses to our overall profitability.

Commitments and Contingent Liabilities

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingent Liabilities

Commitments and contingent liabilities

In the normal course of business, various commitments and contingent liabilities are outstanding that are not reflected in the accompanying consolidated balance sheets.

Our significant trading and off-balance sheet risks are securities, foreign currency and interest rate risk management products, commercial lending commitments, letters of credit and securities lending indemnifications. We assume these risks to reduce interest rate and foreign currency risks, to provide customers with the ability to meet credit and liquidity needs and to hedge foreign currency and interest rate risks. These items involve, to varying degrees, credit, foreign currency and interest rate risk not recognized in the balance sheet. Our off-balance sheet risks are managed and monitored in manners similar to those used for on-balance sheet risks. Significant industry concentrations related to credit exposure at March 31, 2013 are disclosed in the financial institutions portfolio exposure table and the commercial portfolio exposure table below.

Financial institutions portfolio exposure (in billions)	March 31, 2013
	Loans		Unfunded commitments		Total exposure
Banks	$	8.6	$	1.9	$	10.5
Securities industry	3.6		1.9		5.5

Manufacturing	0.3		5.5		5.8
Media and telecom	0.1		1.5		1.6
Total	$	1.5	$	18.7	$	20.2

Major concentrations in securities lending are primarily to broker-dealers and are generally collateralized with cash. Securities lending transactions are discussed below.

The following table presents a summary of our off-balance sheet credit risks, net of participations.

Off-balance sheet credit risks	March 31,		Dec. 31,
(in millions)	2013		2012
Lending commitments (a)	$	31,522	$	31,265
Standby letters of credit (b)	7,129		7,167
Commercial letters of credit	156		219
Securities lending indemnifications	251,977		245,717

(a) Net of participations totaling $612 million at March 31, 2013 and $350 million at Dec. 31, 2012.

(b) Net of participations totaling $1.0 billion at March 31, 2013 and $1.0 billion at Dec. 31, 2012.

Included in lending commitments are facilities that provide liquidity for variable rate tax-exempt securities wrapped by monoline insurers. The credit approval for these facilities is based on an assessment of the underlying tax-exempt issuer and considers factors other than the financial strength of the monoline insurer.

The total potential loss on undrawn lending commitments, standby and commercial letters of credit, and securities lending indemnifications is equal to the total notional amount if drawn upon, which does not consider the value of any collateral.

Since many of the commitments are expected to expire without being drawn upon, the total amount does not necessarily represent future cash requirements. A summary of lending commitment maturities is as follows: $9.2 billion in less than one year, $21.9 billion in one to five years and $0.4 billion over five years.

Standby letters of credit (“SBLC”) principally support corporate obligations. As shown in the off-balance sheet credit risks table, the maximum potential exposure of SBLCs was $7.1 billion at March 31, 2013 and $7.2 billion at Dec. 31, 2012, and includes $677 million and $781 million that were collateralized with cash and securities at March 31, 2013 and Dec. 31, 2012, respectively. At March 31, 2013, $3.9 billion of the SBLCs will expire within one year and $3.2 billion in one to five years.

We must recognize, at the inception of standby letters of credit and foreign and other guarantees, a liability for the fair value of the obligation undertaken in issuing the guarantee. As required by ASC 460 - Guarantees, the fair value of the liability, which was recorded with a corresponding asset in other assets, was estimated as the present value of contractual customer fees.

The estimated liability for losses related to these commitments and SBLCs, if any, is included in the allowance for lending-related commitments. The allowance for lending-related commitments was $121 million at March 31, 2013 and $121 million at Dec. 31, 2012.

Payment/performance risk of SBLCs is monitored using both historical performance and internal ratings criteria. BNY Mellon’s historical experience is that SBLCs typically expire without being funded. SBLCs below investment grade are monitored closely for payment/performance risk. The table below shows SBLCs by investment grade:

Standby letters of credit	March 31,		Dec. 31,
	2013		2012
Investment grade	91	%	93	%
Noninvestment grade	9	%	7	%

A commercial letter of credit is normally a short-term instrument used to finance a commercial contract for the shipment of goods from a seller to a buyer. Although the commercial letter of credit is contingent upon the satisfaction of specified conditions, it represents a credit exposure if the buyer defaults on the underlying transaction. As a result, the total contractual amounts do not necessarily represent future cash requirements. Commercial letters of credit totaled $156 million at March 31, 2013 compared with $219 million at Dec. 31, 2012.

A securities lending transaction is a fully collateralized transaction in which the owner of a security agrees to lend the security (typically through an agent, in our case, The Bank of New York Mellon), to a borrower, usually a broker-dealer or bank, on an open, overnight or term basis, under the terms of a prearranged contract, which normally matures in less than 90 days.

We typically lend securities with indemnification against borrower default. We generally require the borrower to provide cash collateral with a value of 102% of the fair value of the securities borrowed, which is monitored on a daily basis, thus reducing credit risk. Market risk can also arise in securities lending transactions. These risks are controlled through policies limiting the level of risk that can be undertaken. Securities lending transactions are generally entered into only with highly rated counterparties. Securities lending indemnifications were secured by collateral of $259 billion at March 31, 2013 and $253 billion at Dec. 31, 2012.

We expect many of these guarantees to expire without the need to advance any cash. The revenue associated with guarantees frequently depends on the credit rating of the obligor and the structure of the transaction, including collateral, if any.

Exposure for certain administrative errors

In connection with certain funds that we manage, we may be liable to the funds for certain administrative errors. The errors relate to questions about the resident status of certain offshore tax exempt funds, potentially exposing the Company to a tax liability related to the funds’ earnings. The Company is in discussions with tax authorities regarding the funds. In addition to amounts accrued, we believe it is reasonably possible that we could have a potential additional exposure of up to $175 million.

Indemnification Arrangements

We have provided standard representations for underwriting agreements, acquisition and divestiture agreements, sales of loans and commitments, and other similar types of arrangements and customary indemnification for claims and legal proceedingsrelated to providing financial services that are not otherwise included above. Insurance has been purchased to mitigate certain of these risks. Generally, there are no stated or notional amounts included in these indemnifications and the contingencies triggering the obligation for indemnification are not expected to occur. Furthermore, often counterparties to these transactions provide us with comparable indemnifications. We are unable to develop an estimate of the maximum payout under these indemnifications for several reasons. In addition to the lack of a stated or notional amount in a majority of such indemnifications, we are unable to predict the nature of events that would trigger indemnification or the level of indemnification for a certain event. We believe, however, that the possibility that we will have to make any material payments for these indemnifications is remote. At March 31, 2013 and Dec. 31, 2012, we had no material liabilities under these arrangements.

Clearing and Settlement Exchanges

We are a minority equity investor in, and member of, several industry clearing or settlement exchanges through which foreign exchange, securities, or other transactions settle. Certain of these industry clearing and settlement exchanges require their members to guarantee their obligations and liabilities or to provide financial support in the event other members do not honor their obligations. We believe the likelihood that a clearing or settlement exchange (of which we are a member) would become insolvent is remote. Additionally, certain settlement exchanges have implemented loss allocation policies that enable the exchange to allocate settlement losses to the members of the exchange. It is not possible to quantify such mark-to-market loss until the loss occurs. In addition, any ancillary costs that occur as a result of any mark-to-market loss cannot be quantified. At March 31, 2013 and Dec. 31, 2012, we have not recorded any material liabilities under these arrangements.

Legal proceedings

In the ordinary course of business, BNY Mellon and its subsidiaries are routinely named as defendants in or made parties to pending and potential legal actions and regulatory matters. Claims for significant monetary damages are often asserted in many of these legal actions, while claims for disgorgement, penalties and/or other remedial sanctions may be sought in regulatory matters. It is inherently difficult to predict the eventual outcomes of such matters given their complexity and the particular facts and circumstances at issue in each of these matters. However, on the basis of our current knowledge and understanding, we do not believe that judgments or settlements, if any, arising from these matters (either individually or in the aggregate, after giving effect to applicable reserves and insurance coverage) will have a material adverse effect on the consolidated financial position or liquidity of BNY Mellon, although they could have a material effect on net income in a given period.

In view of the inherent unpredictability of outcomes in litigation and regulatory matters, particularly where (i) the damages sought are substantial or indeterminate, (ii) the proceedings are in the early stages, or (iii) the matters involve novel legal theories or a large number of parties, as a matter of course there is considerable uncertainty surrounding the timing or ultimate resolution of litigation and regulatory matters, including a possible eventual loss, fine, penalty or business impact, if any, associated with each such matter. In accordance with applicable accounting guidance, BNY Mellon establishes accruals for litigation and regulatory matters when those matters proceed to a stage where they present loss contingencies that are both probable and reasonably estimable. In such cases, there may be a possible exposure to loss in excess of any amounts accrued. BNY Mellon will continue to monitor such matters for developments that could affect the amount of the accrual, and will adjust the accrual amount as appropriate. If the loss contingency in question is not both probable and reasonably estimable, BNY Mellon does not establish an accrual and the matter will continue to be monitored for any developments that would make the loss contingency both probable and reasonably estimable. BNY Mellon believes that its accruals for legal proceedings are appropriate and, in the aggregate, are not material to the consolidated financial position of BNY Mellon, although future accruals could have a material effect on net income in a given period.

For certain of those matters described herein for which a loss contingency may, in the future, be reasonably possible (whether in excess of a related accrued liability or where there is no accrued liability), BNY Mellon is currently unable to estimate a range of reasonably possible loss. For those matters where BNY Mellon is able to estimate a reasonably possible loss, exclusive of matters described in Note 11 of the Notes to Consolidated Financial Statements, subject to the accounting and reporting requirements of ASC 740 (FASB Interpretation 48), the aggregate range of such reasonably possible loss is up to $470 million in excess of the accrued liability (if any) related to those matters.

The following describes certain judicial, regulatory and arbitration proceedings involving BNY Mellon:

Sentinel Matters

As previously disclosed, on Jan. 18, 2008, The Bank of New York Mellon filed a proof of claim in the Chapter 11 bankruptcy proceeding of Sentinel Management Group, Inc. (“Sentinel”) pending in federal court in the Northern District of Illinois, seeking to recover approximately $312 million loaned to Sentinel and secured by securities and cash in an account maintained by Sentinel at The Bank of New York Mellon. On March 3, 2008, the bankruptcy trustee filed an adversary complaint against The Bank of New York Mellon seeking to disallow The Bank of New York Mellon’s claim and seeking damages for allegedly aiding and abetting Sentinel insiders in misappropriating customer assets and improperly using those assets as collateral for the loan. In a decision dated Nov. 3, 2010, the court found for The Bank of New York Mellon and against the bankruptcy trustee, holding that The Bank of New York Mellon’s loan to Sentinel is valid, fully secured and not subject to equitable subordination. The bankruptcy trustee appealed this decision, and on August 9, 2012, the United States Court of Appeals for the Seventh Circuit issued a decision affirming the trial court’s judgment. On September 7, 2012, the bankruptcy trustee filed a petition for rehearing on the fraudulent transfer portion of the opinion and, on November 30, 2012, the Court of Appeals withdrew its opinion and vacated its judgment. The appeal remains under consideration.

As previously disclosed, in November 2009, the Division of Enforcement of the U.S. Commodities Futures Trading Commission (“CFTC”) indicated that it is considering a recommendation to the CFTC that it file a civil enforcement action against The Bank of New York Mellon for possible violations of the Commodity Exchange Act and CFTC regulations in connection with its relationship to Sentinel. The Bank of New York Mellon responded in writing to the CFTC on Jan. 29, 2010 and provided an explanation as to why an enforcement action is unwarranted.

Securities Lending Matters

As previously disclosed, BNY Mellon or its affiliates have been named as defendants in a number of lawsuits initiated by participants in BNY Mellon’s securities lending program, which is a part of BNY Mellon’s Investment Services business. The lawsuits were filed on various dates from 2009 to 2013,and are currently pending in courts in New York, South Carolina, North Carolina and Illinois and in commercial court in London. The complaints assert contractual, statutory, and common law claims, including claims for negligence and breach of fiduciary duty. The plaintiffs allege losses in connection with the investment of securities lending collateral, including losses related to investments in Sigma Finance Inc. (“Sigma”), Lehman Brothers Holdings, Inc. and certain asset-backed securities, and seek damages as to those losses.

Matters Relating To Bernard L. Madoff

As previously disclosed, on May 11, 2010, the New York State Attorney General commenced a civil lawsuit against Ivy Asset Management LLC (“Ivy”), a subsidiary of BNY Mellon that manages primarily funds-of-hedge-funds, and two of its former officers in New York state court. The lawsuit alleges that Ivy, in connection with its role as sub-advisor to investment managers whose clients invested with Madoff, did not disclose certain material facts about Madoff. The complaint seeks an accounting of compensation received from January 1997 to the present by the Ivy defendants in connection with the Madoff investments, and unspecified damages, including restitution, disgorgement, costs and attorneys’ fees.

As previously disclosed, on Oct. 21, 2010, the U.S. Department of Labor commenced a civil lawsuit against Ivy, two of its former officers, and others in federal court in the Southern District of New York. The lawsuit alleges that Ivy violated the Employee Retirement Income Security Act (“ERISA”) by failing to disclose certain material facts about Madoff to investment managers subadvised by Ivy whose clients included employee benefit plan investors. The complaint seeks disgorgement and damages.

As previously disclosed, Ivy or its affiliates have been named in a number of civil lawsuits filed beginning Jan. 27, 2009 relating to certain investment funds that allege losses due to the Madoff investments. Ivy acted as a sub-advisor to the investment managers of some of those funds. Plaintiffs assert various causes of action including securities and common-law fraud. Certain of the cases have been certified as class actions and/or assert derivative claims on behalf of the funds. Most of the cases have been consolidated in two actions in federal court in the Southern District of New York, with certain cases filed in New York State Supreme Court for New York and Nassau counties.

On Nov. 13, 2012, Ivy entered into a settlement agreement with the New York State Attorney General, the U.S. Department of Labor, and the civil lawsuit plaintiffs that would settle all claims for $210 million. The settlement is subject to judicial approval, which the various courts have preliminarily given. A hearing on final approval was held March 15, 2013; we await the Court’s ruling.

On Dec. 8, 2010, the Trustee overseeing the Madoff liquidation sued many of the same defendants in bankruptcy court in New York, seeking to avoid withdrawals from Madoff investments made by various funds-of-funds (including six funds-of-funds managed by Ivy). On Oct. 12, 2012, Ivy and the Trustee entered into a written settlement agreement, agreeing to settle all claims for $2 million. The settlement was approved by the Bankruptcy Court on Dec. 4, 2012.

Medical Capital Litigations

As previously disclosed, The Bank of New York Mellon has been named as a defendant in a number of class actions and non-class actions brought by numerous plaintiffs in connection with its role as indenture trustee for debt issued by affiliates of Medical Capital Corporation. The actions, filed in late 2009 and currently pending in federal court in the Central District of California, allege that The Bank of New York Mellon breached its fiduciary and contractual obligations to the holders of the underlying securities, and seek unspecified damages.

On Dec. 21, 2012, The Bank of New York Mellon entered into a settlement agreement with the plaintiffs and the Federal Equity Receiver for Medical Capital Corporation and its affiliates. Under the terms of the settlement, The Bank of New York Mellon will make a payment of $114 million in exchange for a complete release of claims. The settlement was preliminarily approved on Feb. 28, 2013.

Foreign Exchange Matters

As previously disclosed, beginning in December 2009, government authorities have been conducting inquiries seeking information relating primarily to standing instruction foreign exchange transactions in connection with custody services BNY Mellon provides to public pension plans and certain other custody clients. BNY Mellon is cooperating with these inquiries.

In addition, in early 2011, as previously disclosed, the Virginia Attorney General’s Office and the Florida Attorney General’s Office each intervened in a qui tam lawsuit pending in its jurisdiction, and, on Aug. 11, 2011, filed superseding complaints. On Nov. 9, 2012, the Virginia court, which had previously dismissed all of the claims against BNY Mellon, dismissed the lawsuit with prejudice by agreement of the parties. On Oct. 4, 2011, the New York Attorney General’s Office, the New York City Comptroller and various city pension and benefit funds filed a lawsuit asserting, claims under the Martin Act and state and city false claims acts. Also, on Oct. 4, 2011, the United States Department of Justice (“DOJ”) filed a civil lawsuit seeking civil penalties under 12 U.S.C. Section 1833a and injunctive relief under 18 U.S.C. Section 1345 based on alleged ongoing violations of 18 U.S.C. Sections 1341 and 1343 (mail and wire fraud). On Jan. 17, 2012, the court approved a partial settlement resolving the DOJ’s claim for injunctive relief. In October 2011, several political subdivisions of the state of California intervened in a qui tam lawsuit that was removed to federal district court in California. On March 30, 2012, the court dismissed certain of plaintiffs’ claims, including all claims under the California False Claims Act. Certain plaintiffs have since filed an amended complaint. Several plaintiffs also had their claims dismissed for improper venue and one refiled on Sept. 5, 2012 in a different California federal district court. On Oct. 26, 2011, the Massachusetts Securities Division filed an Administrative Complaint against BNY Mellon.

BNY Mellon has also been named as a defendant in several putative class action federal lawsuits filed on various dates in 2011 and 2012. The complaints, which assert claims including breach of contract and ERISA violations, all allege that the prices BNY Mellon charged for standing instruction foreign exchange transactions executed in connection with custody services provided by BNY Mellon were improper. In addition, BNY Mellon has been named as a nominal defendant in several derivative lawsuits filed 2011 and 2012 in state and federal court in New York. BNY Mellon has also been named in a qui tam lawsuit filed on May 22, 2012 in Massachusetts state court. To the extent these lawsuits are pending in federal court, they have been consolidated for pre-trial purposes in federal court in New York.

Lyondell Litigation

As previously disclosed, in an action filed in New York State Supreme Court for New York County, on Sept. 14, 2010, plaintiffs as holders of debt issued by Basell AF in 2005 allege that The Bank of New York Mellon, as indenture trustee, breached its contractual and fiduciary obligations by executing an intercreditor agreement in 2007 in connection with Basell’s acquisition of Lyondell Chemical Company. Plaintiffs are seeking damages for their alleged losses resulting from the execution of the 2007 intercreditor agreement that allowed the company to increase the amount of its senior debt.

Tax Litigation

As previously disclosed, on Aug. 17, 2009, BNY Mellon received a Statutory Notice of Deficiency disallowing tax benefits for the 2001 and 2002 tax years in connection with a 2001 transaction that involved the payment of UK corporate income taxes that were credited against BNY Mellon’s U.S. corporate income tax liability. On Nov. 10, 2009, BNY Mellon filed a petition with the U.S. Tax Court contesting the disallowance of the benefits. Trial was held from April 16 to May 17, 2012. On Feb. 11, 2013, the Tax Court upheld the IRS’s Notice of Deficiency and disallowed BNY Mellon’s tax credits and associated transaction costs.  BNY Mellon will appeal the Tax Court’s ruling. See Note 11 of the Notes to Consolidated Financial Statements for additional information.

Mortgage-Securitization Trusts Proceeding

As previously disclosed, The Bank of New York Mellon as trustee is the petitioner in a legal proceeding filed in New York State Supreme Court, New York County on June 29, 2011, seeking approval of a proposed settlement involving Bank of America Corporation and bondholders in certain Countrywide residential mortgage-securitization trusts. The New York and Delaware Attorneys General have intervened in this proceeding.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

The accounting and financial reporting policies of BNY Mellon, a global financial services company, conform to U.S. generally accepted accounting principles (“GAAP”) and prevailing industry practices.

The accompanying consolidated financial statements are unaudited. In the opinion of management, all adjustments necessary for a fair presentation of financial position, results of operations and cash flows for the periods have been made. These financial statements should be read in conjunction with BNY Mellon’s Annual Report on Form 10-K for the year ended Dec. 31, 2012. Certain immaterial reclassifications have been made to prior periods to place them on a basis comparable with current period presentation.

Use of Estimates

Use of estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates based upon assumptions about future economic and market conditions which affect reported amounts and related disclosures in our financial statements. Although our current estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that actual conditions could be worse than anticipated in those estimates, which could materially affect our results of operations and financial condition. Amounts subject to estimates are items such as the allowance for loan losses and lending-related commitments, the fair value of financial instruments and other-than-temporary impairments, goodwill and intangible assets and pension accounting. Among other effects, such changes in estimates could result in future impairments of investment securities, goodwill and intangible assets and establishment of allowances for loan losses and lending-related commitments as well as changes in pension and post-retirement expense.

The carrying amounts of our financial instruments (i.e., monetary assets and liabilities) are determined under different accounting methods - see Note 1 of the Notes to Consolidated Financial Statements in our 2012 Annual Report. The following disclosure discusses these instruments on a uniform fair value basis. However, active markets do not exist for a significant portion of these instruments. For financial instruments where quoted prices from identical assets and liabilities in active markets do not exist, we determine fair value based on discounted cash flow analysis and comparison to similar instruments. Discounted cash flow analysis is dependent upon estimated future cash flows and the level of interest rates. Other judgments would result in different fair values. The assumptions we used at March 31, 2013 and Dec. 31, 2012 include discount rates ranging principally from 0.20% to 4.87%. The fair value information supplements the basic financial statements and other traditional financial data presented throughout this report.

A summary of the practices used for determining fair value and the respective level in the valuation hierarchy for financial assets and liabilities not recorded at fair value follows.

Interest-bearing deposits with the Federal Reserve and other central banks and interest-bearing deposits with banks

The estimated fair value of interest-bearing deposits with the Federal Reserve and other central banks is equal to the book value as these interest-bearing deposits are generally considered cash equivalents. These instruments are classified as Level 2 within the valuation hierarchy. The estimated fair value of interest-bearing deposits with banks is generally determined using discounted cash flows and duration of the instrument to maturity. The primary inputs used to value these transactions are interest rates based on current LIBOR market rates and time to maturity. Interest-bearing deposits with banks are classified as Level 2 within the valuation hierarchy.

Federal funds sold and securities purchased under resale agreements

The estimated fair value of federal funds sold and securities purchased under resale agreements is based on inputs such as interest rates and tenors. Federal funds sold and securities purchased under resale agreements are classified as Level 2 within the valuation hierarchy.

Securities held-to-maturity

Where quoted prices are available in an active market for identical assets and liabilities, we classify the securities as Level 1 within the valuation hierarchy. Securities are defined as both long and short positions. Level 1 securities include U.S. Treasury securities.

If quoted market prices are not available for identical assets and liabilities, we estimate fair value using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. Examples of such instruments, which would generally be classified as Level 2 within the valuation hierarchy, include certain agency and non-agency mortgage-backed securities, commercial mortgage-backed securities and state and political subdivision securities. For securities where quotes from active markets are not available for identical securities, we determine fair value primarily based on pricing sources with reasonable levels of price transparency that employ financial models or obtain comparison to similar instruments to arrive at “consensus” prices.

Specifically, the pricing sources obtain active market prices for similar types of securities (e.g., vintage, position in the securitization structure) and ascertain variables such as discount rate and speed of prepayment for the types of transaction and apply such variables to similar types of bonds. We view these as observable transactions in the current marketplace and classify such securities as Level 2 within the valuation hierarchy.

Loans

For residential mortgage loans, fair value is estimated using discounted cash flow analysis, adjusting where appropriate for prepayment estimates, using interest rates currently being offered for loans with similar terms and maturities to borrowers. The estimated fair value of margin loans and overdrafts is equal to the book value due to the short-term nature of these assets. The estimated fair value of other types of loans is determined using discounted cash flows. Inputs include current LIBOR market rates adjusted for credit spreads. These loans are generally classified as Level 2 within the valuation hierarchy.

Other financial assets

Other financial assets include cash, the Federal Reserve Bank stock and accrued interest receivable. Cash is classified as Level 1 within the valuation hierarchy. The Federal Reserve Bank stock is not redeemable or transferable. The estimated fair value of the Federal Reserve Bank stock is based on the issue price and is classified as Level 2 within the valuation hierarchy. Accrued interest receivable is generally short-term. As a result, book value is considered to equal fair value. Accrued interest receivable is included as Level 2 within the valuation hierarchy.

Noninterest-bearing and interest-bearing deposits

Interest-bearing deposits are comprised of money market rate and demand deposits, savings deposits and time deposits. Except for time deposits, book value is considered to equal fair value for these deposits due to their short duration to maturity or payable on demand feature. The fair value of interest-bearing time deposits is determined using discounted cash flow analysis. Inputs primarily consist of current LIBOR market rates and time to maturity. For all noninterest-bearing deposits, book value is considered to equal fair value as a result of the short duration of the deposit. Interest-bearing and noninterest-bearing deposits are classified as Level 2 within the valuation hierarchy.

Federal funds purchased and securities sold under repurchase agreements

The estimated fair value of federal funds purchased and securities sold under repurchase agreements is based on inputs such as interest rates and tenors. Federal funds purchased and securities sold under repurchase agreements are classified as Level 2 within the valuation hierarchy.

Payables to customers and broker-dealers

The estimated fair value of payables to customers and broker-dealers is equal to the book value, due to the demand feature of the payables to customers and broker-dealers, and are classified as Level 2 within the valuation hierarchy.

Borrowings

Borrowings primarily consist of overdrafts of subcustodian account balances in our Investment Services businesses, commercial paper and accrued interest payable. The estimated fair value of overdrafts of subcustodian account balances in our Investment Services businesses is considered to equal book value as a result of the short duration of the overdrafts. Overdrafts are typically repaid within two days. The estimated fair value of our commercial paper is based on discount and duration of the commercial paper. Our commercial paper matures within 397 days from date of issue and is not redeemable prior to maturity or subject to voluntary prepayment. Our commercial paper is included in Level 2 of the valuation hierarchy. Accrued interest payable is generally short-term. As a result, book value is considered to equal fair value. Accrued interest payable is included as Level 2 within the valuation hierarchy.

Long-term debt

The estimated fair value of long-term debt is based on current rates for instruments of the same remaining maturity or quoted market prices for the same or similar issues. Long-term debt is classified as Level 2 within the valuation hierarchy.

Fair Value Measurement

Fair value measurement

The guidance related to “Fair Value Measurement” included in ASC 820 defines fair value as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date and establishes a framework for measuring fair value. It establishes a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date and expands the disclosures about instruments measured at fair value. ASC 820 requires consideration of a company’s own creditworthiness when valuing liabilities.

The standard provides a consistent definition of fair value, which focuses on exit price in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The objective is to determine from weighted indicators of fair value a reasonable point within the range that is most representative of fair value under current market conditions.

Determination of fair value

Following is a description of our valuation methodologies for assets and liabilities measured at fair value. We have established processes for determining fair values. Fair value is based upon quoted market prices in active markets, where available. For financial instruments where quotes from recent exchange transactions are not available, we determine fair value based on discounted cash flow analysis, comparison to similar instruments, and the use of financial models. Discounted cash flow analysis is dependent upon estimated future cash flows and the level of interest rates. Model-based pricing uses inputs of observable prices, where available, for interest rates, foreign exchange rates, option volatilities and other factors. Models are benchmarked and validated by an independent internal risk management function. Our valuation process takes into consideration factors such as counterparty credit quality, liquidity, concentration concerns, and observability of model parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value.

Most derivative contracts are valued using internally developed models which are calibrated to observable market data and employ standard market pricing theory for their valuations. An initial “risk-neutral” valuation is performed on each position assuming time-discounting based on a AA credit curve. Then, to arrive at a fair value that incorporates counter-party credit risk, a credit adjustment is made to these results by discounting each trade’s expected exposures to the counterparty using the counterparty’s credit spreads, as implied by the credit default swap market. We also adjust expected liabilities to the counterparty using BNY Mellon’sown credit spreads, as implied by the credit default swap market. Accordingly, the valuation of our derivative position is sensitive to the current changes in our own credit spreads as well as those of our counterparties.

In certain cases, recent prices may not be observable for instruments that trade in inactive or less active markets. Upon evaluating the uncertainty in valuing financial instruments subject to liquidity issues, we make an adjustment to their value. The determination of the liquidity adjustment includes the availability of external quotes, the time since the latest available quote and the price volatility of the instrument.

Certain parameters in some financial models are not directly observable and, therefore, are based on management’s estimates and judgments. These financial instruments are normally traded less actively. We apply valuation adjustments to mitigate the possibility of error and revision in the model based estimate value. Examples include products where parameters such as correlation and recovery rates are unobservable.

The methods described above for instruments that trade in inactive or less active markets may produce a current fair value calculation that may not be indicative of net realizable value or reflective of future fair values. We believe our methods of determining fair value are appropriate and consistent with other market participants. However, the use of different methodologies or different assumptions to value certain financial instruments could result in a different estimate of fair value.

Valuation hierarchy

ASC 820 established a three-level valuation hierarchy for disclosure of fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are described below.

Level 1: Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 1 assets and liabilities include debt and equity securities and derivative financial instruments actively traded on exchanges and U.S. Treasury securities that are actively traded in highly liquid over-the-counter markets.

Level 2: Observable inputs other than Level 1 prices, for example, quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs that are observable or can be corroborated, either directly or indirectly, for substantially the full term of the financial instrument. Level 2 assets and liabilities include debt instruments that are traded less frequently than exchange-traded securities and derivative instruments whose model inputs are observable in the market or can be corroborated by market-observable data. Examples in this category are agency and non-agency mortgage-backed securities, corporate debt securities and over-the-counter derivative contracts.

Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement. Examples in this category include certain private equity investments, derivative contracts that are highly structured or long-dated, and interests in certain securitized financial assets.

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

Following is a description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy.

Securities

Where quoted prices are available in an active market, we classify the securities within Level 1 of the valuation hierarchy. Securities include both long and short positions. Level 1 securities include highly liquid government bonds, money market mutual funds and exchange-traded equities.

If quoted market prices are not available, we estimate fair values using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. Examples of such instruments, which would generally be classified within Level 2 of the valuation hierarchy, include agency and non-agency mortgage-backed securities, commercial mortgage-backed securities, sovereign debt, corporate bonds and foreign covered bonds.

For securities where quotes from recent transactions are not available for identical securities, wedetermine fair value primarily based on pricing sources with reasonable levels of price transparency that employ financial models or obtain comparison to similar instruments to arrive at “consensus” prices.

Specifically, the pricing sources obtain recent transactions for similar types of securities (e.g., vintage, position in the securitization structure) and ascertain variables such as discount rate and speed of prepayment for the types of transaction and apply such variables to similar types of bonds. We view these as observable transactions in the current marketplace and classify such securities as Level 2. Pricing sources discontinue pricing any specific security whenever they determine there is insufficient observable data to provide a good faith opinion on price.

In addition, we have significant investments in more actively traded agency RMBS and other types of securities such as sovereign debt. The pricing sources derive the prices for these securities largely from quotes they obtain from three major inter-dealer brokers. The pricing sources receive their daily observed trade price and other information feeds from the inter-dealer brokers.

For securities with bond insurance, the financial strength of the insurance provider is analyzed and that information is included in the fair value assessment for such securities.

In certain cases where there is limited activity or less transparency around inputs to the valuation, we classify those securities in Level 3 of the valuation hierarchy. Securities classified within Level 3 primarily include securities of state and political subdivisions and distressed debt securities.

At March 31, 2013, more than 99% of our securities were valued by pricing sources with reasonable levels of price transparency. Less than 1% of our securities were priced based on economic models and non-binding dealer quotes, and are included in Level 3 of the ASC 820 hierarchy.

Consolidated collateralized loan obligations

BNY Mellon values assets in consolidated CLOs using observable market prices observed from the secondary loan market. The returns to the note holders are solely dependent on the assets and accordingly equal the value of those assets. Based on the structure of the CLOs, the valuation of the assets is attributable to the senior note holders. Changes in the values of assets and liabilities are reflected in the income statement as investment income and interest of investment management fund note holders, respectively.

Derivatives

We classify exchange-traded derivatives valued using quoted prices in Level 1 of the valuation hierarchy. Examples include exchanged-traded equity and foreign exchange options. Since few other classes of derivative contracts are listed on an exchange, most of our derivative positions are valued using internally developed models that use as their basis readily observable market parameters, and we classify them in Level 2 of the valuation hierarchy. Such derivatives include basic swaps and options and credit default swaps.

Derivatives valued using models with significant unobservable market parameters in markets that lack two-way flow are classified in Level 3 of the valuation hierarchy. Examples include long-dated interest rate or currency swaps and options, where parameters may be unobservable for longer maturities; and certain products, where correlation risk is unobservable. The fair value of these derivatives compose less than 1% of our derivative financial instruments. Additional disclosures of derivative instruments are provided in Note 17 of the Notes to Consolidated Financial Statements.

Loans and unfunded lending-related commitments

Where quoted market prices are not available, we generally base the fair value of loans and unfunded lending-related commitments on observable market prices of similar instruments, including bonds, credit derivatives and loans with similar characteristics. If observable market prices are not available, we base the fair value on estimated cash flows adjusted for credit risk which are discounted using an interest rate appropriate for the maturity of the applicable loans or the unfunded lending-related commitments.

Unrealized gains and losses, if any, on unfunded lending-related commitments carried at fair value are classified in Other assets and Other liabilities, respectively. Loans and unfunded lending-related commitments carried at fair value are generally classified within Level 2 of the valuation hierarchy.

Seed capital

In our Investment Management business, we manage investment assets, including equities, fixed income, money market and alternative investment funds for institutions and other investors. As part of that activity, we make seed capital investments in certain funds. Seed capital is included in other assets. When applicable, we value seed capital based on the published NAV of the fund. We include funds in which ownership interests in the fund are publicly traded in an active market and institutional funds in which investors trade in and out daily in Level 1 of the valuation hierarchy. We include open-end funds where investors are allowed to sell their ownership interest back to the fund less frequently than daily and where our interest in the fund contains no other rights or obligations in Level 2 of the valuation hierarchy. However, we generally include investments in funds that allow investors to sell their ownership interest back to the fund less frequently than monthly in Level 3, unless actual redemption prices are observable.

For other types of investments in funds, we consider all of the rights and obligations inherent in our ownership interest, including the reported NAV as well as other factors that affect the fair value of our interest in the fund. To the extent the NAV measurements reported for the investments are based on unobservable inputs or include other rights and obligations (e.g., obligation to meet cash calls), we generally classify them in Level 3 of the valuation hierarchy.

Certain interests in securitizations

For certain interests in securitizations that are classified in securities available-for-sale, trading assets and long-term debt, we use discounted cash flow models, which generally include assumptions of projected finance charges related to the securitized assets, estimated net credit losses, prepayment assumptions and estimates of payments to third-party investors. When available, we compare our fair value estimates and assumptions to market activity and to the actual results of the securitized portfolio.

Private equity investments

Our Other segment includes holdings of nonpublic private equity investment through funds managed by third-party investment managers. We value private equity investments initially based upon the transaction price, which we subsequently adjust to reflect expected exit values as evidenced by financing and sale transactions with third parties or through ongoing reviews by the investment managers.

Private equity investments also include publicly held equity investments, generally obtained through the initial public offering of privately held equity investments. These equity investments are often held in a partnership structure. Publicly held investments are marked-to-market at the quoted public value less adjustments for regulatory or contractual sales restrictions or adjustments to reflect the difficulty in selling a partnership interest.

Discounts for restrictions are quantified by analyzing the length of the restriction period and the volatility of the equity security. Publicly held private equity investments are primarily classified in Level 2 of the valuation hierarchy.

The following tables present the financial instruments carried at fair value at March 31, 2013 and Dec. 31 2012, by caption on the consolidated balance sheet and by ASC 820 valuation hierarchy (as described above). We have included credit ratings information in certain of the tables because the information indicates the degree of credit risk to which we are exposed, and significant changes in ratings classifications could result in increased risk for us. There were no material transfers between Level 1 and Level 2 during the first quarter of 2013.

Securitizations And Variable Interest Entities Disclosure [Abstract]

Securitizations and variable interest entities

Securitizations and variable interest entities

BNY Mellon’s VIEs generally include retail, institutional and alternative investment funds offered to its retail and institutional customers in which it acts as the fund’s investment manager. BNY Mellon earns management fees on these funds as well as performance fees in certain funds. It may also provide start-up capital in its new funds. These VIEs are included in the scope of ASU 2010-10 and are reviewed for consolidation based on the guidance in ASC 810.

BNY Mellon has other VIEs, including securitization trusts, which are no longer considered qualifying special purpose entities, and CLOs, in which BNY Mellon serves as the investment manager. In addition, we provide trust and custody services for a fee to entities sponsored by other corporations in which we have no other interest. These VIEs are evaluated under the guidance included in ASU 2009-17. BNY Mellon has two securitizations and several CLOs, which are assessed for consolidation in accordance with ASU 2009-17.

The following tables present the incremental assets and liabilities included in BNY Mellon’s consolidated financial statements, after applying intercompany eliminations, as of March 31, 2013 and Dec. 31, 2012, based on the assessments performed in accordance with ASC 810 and ASU 2009-17. The net assets of any consolidated VIE are solely available to settle the liabilities of the VIE and to settle any investors’ ownership liquidation requests, including any seed capital invested in the VIE by BNY Mellon.

BNY Mellon is not contractually required to provide financial or any other support to any of our VIEs. Additionally, creditors of any consolidated VIEs do not have any recourse to the general credit of BNY Mellon.

Seed capital and private equity investments valued using net asset value per share

In our Investment Management business, we manage investment assets, including equities, fixed income, money market and alternative investment funds for institutions and other investors. As part of that activity we make seed capital investments in certain funds. BNY Mellon also holds private equity investments, which consist of investments in private equity funds, mezzanine financings and direct equity investments. Seed capital and private equity investments are included in other assets. Consistent with our policy to focus on our core activities, we continue to reduce our exposure to private equity investments.

The fair value of these investments has been estimated using the net asset value (“NAV”) per share of BNY Mellon’s ownership interest in the funds. The table below presents information about BNY Mellon’s investments in seed capital and private equity investments.

Accounting changes and new accounting guidance

ASU 2011-11 - Disclosures about Offsetting Assets and Liabilities

In December 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU 2011-11”), “Disclosures about Offsetting Assets and Liabilities”. Entities are required to disclose both gross information and net information about both instruments and transactions eligible for offset in the balance sheet and instruments and transactions subject to an agreement similar to a master netting arrangement. This scope would include derivatives, sale and repurchase agreements and reverse sale and repurchase agreements, and securities borrowing and securities lending arrangements. See Note 17 “Derivative instruments” for our disclosure.

ASU 2012-02 - Testing Indefinite-Lived Intangible Assets for Impairment

In July 2012, the FASB issued ASU 2012-02, “Testing Indefinite-Lived Intangible Assets for Impairment”. This guidance allows an entity an option to first assess qualitative factors to determine whether it is more likely than not (a likelihood of more than 50 percent) that an indefinite-lived intangible asset is impaired. If the intangible asset is impaired, an entity is required to perform the quantitative impairment test. An entity is not required to calculate the fair value of an indefinite-lived intangible asset and perform the quantitative impairment test unless the entity determines that it is more likely than not that the asset is impaired.

ASU 2013-02 - Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income

In February 2013, the FASB issued ASU 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income”. This ASU requires the presentation of the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income. See Note 14 “Other comprehensive income (loss)” for our disclosure.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of presentation

Basis of Presentation

The accounting and financial reporting policies of BNY Mellon, a global financial services company, conform to U.S. generally accepted accounting principles (“GAAP”) and prevailing industry practices.

The accompanying consolidated financial statements are unaudited. In the opinion of management, all adjustments necessary for a fair presentation of financial position, results of operations and cash flows for the periods have been made. These financial statements should be read in conjunction with BNY Mellon’s Annual Report on Form 10-K for the year ended Dec. 31, 2012. Certain immaterial reclassifications have been made to prior periods to place them on a basis comparable with current period presentation.

Use of estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates based upon assumptions about future economic and market conditions which affect reported amounts and related disclosures in our financial statements. Although our current estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that actual conditions could be worse than anticipated in those estimates, which could materially affect our results of operations and financial condition. Amounts subject to estimates are items such as the allowance for loan losses and lending-related commitments, the fair value of financial instruments and other-than-temporary impairments, goodwill and intangible assets and pension accounting. Among other effects, such changes in estimates could result in future impairments of investment securities, goodwill and intangible assets and establishment of allowances for loan losses and lending-related commitments as well as changes in pension and post-retirement expense.

(a) The carrying value of the Series C preferred stock is recorded net of issuance costs.

Holders of both the Series A and Series C preferred stock issues are entitled to receive dividends on each dividend payment date (March 20, June 20, September 20 and December 20 of each year), if declared by BNY Mellon’s Board of Directors. BNY Mellon’s ability to declare or pay dividends on, or purchase, redeem or otherwise acquire, shares of our common stock or any of our shares that rank junior to the preferred stock as to the payment of dividends and/or the distribution of any assets on any liquidation, dissolution or winding-up of BNY Mellon will be prohibited, subject to certain restrictions, in the event that we do not declare and pay in full preferred dividends for the then current dividend period of the Series A preferred stock or the last preceding dividend period of the Series C preferred stock.

All of the outstanding shares of the Series A preferred stock are owned by Mellon Capital IV, which will pass through any dividend on the Series A preferred stock to the holders of its Normal Preferred Capital Securities. All of the outstanding shares of the Series C preferred stock are held by the depositary of the depositary shares, which will pass through the applicable portion of any dividend on the Series C Preferred Stock to the holders of record of the depositary shares.

The preferred stock is not subject to the operation of a sinking fund and is not convertible into, or exchangeable for, shares of our common stock or any other class or series of our other securities. Subject to the restrictions in BNY Mellon’s 2007 replacement capital covenant, subsequently amended on May 8 and Sept. 11, 2012, we may redeem the Series A preferred stock, in whole or in part, at our option. We may also, at our option, redeem the shares of the Series C preferred stock in whole or in part, on or after the dividend payment date in September 2017, or in whole but not in part at any time within 90 days following a regulatory capital treatment event (as defined in the Certificate of Designations of the Series C preferred stock).

The terms of the Series A preferred stock and the Series C preferred stock are more fully described in each of their Certificate of Designations, each of which is filed as an Exhibit to this Form 10-Q.

Included in these loans are nonperforming loans of $161 million at March 31, 2013 and $174 million at Dec. 31, 2012. These loans are recorded at fair value and therefore do not impact the provision for credit losses and allowance for loan losses, and accordingly are excluded from the nonperforming assets table above.

At March 31, 2013, undrawn commitments to borrowers whose loans were classified as nonaccrual or reduced rate were not material.

Troubled debt restructurings (“TDRs”)

A modified loan is considered a TDR if the debtor is experiencing financial difficulties and the creditor grants a concession to the debtor that would not otherwise be considered. A TDR may include a transfer of real estate or other assets from the debtor to the creditor, or a modification of the term of the loan. Not all modified loans are considered TDRs.

The following table presents TDRs that occurred in the first quarter of 2013, the fourth quarter of 2012 and the first quarter of 2012.

TDRs	March 31, 2013					Dec. 31, 2012					March 31, 2012

Other residential mortgages

The modifications of the other residential mortgage loans in the first quarter of 2013, fourth quarter of 2012 and first quarter of 2012 consisted of reducing the stated interest rates, and in certain cases, a forbearance of default and extending the maturity dates. The value of modified loans is based on the fair value of the collateral. Probable loss factors are applied to the value of the modified loans to determine the allowance for credit losses.

Wealth management loans and mortgages

The modifications of the wealth management loans and mortgages in the fourth quarter of 2012 consisted of changes in payment terms and extensions of the maturity dates. The difference between the book value of the loan and the estimated fair value of the collateral is included in the allowance for credit losses.

Commercial

The modification of the commercial exposure in the first quarter of 2012 consisted of changing the stated interest rates and/or extending the maturity dates of the loans. The difference between the book value of the loan and net cash flow discounted at the original loan’s rate, if no observable market price exists, is included in the allowance for credit losses.

Commercial real estate

The modifications of the commercial real estate loans and unfunded lending-related commitments in first quarter of 2012 consisted of changing the stated interest rates and extending the maturity dates of the loans. The difference between the book value of the loan and the estimated fair value of the collateral is included in the allowance for credit losses.

Foreign

The modifications of foreign loans in the first quarter of 2012 consisted of extending the maturity date of the loan. The difference between the book value of the loan and the net present value discounted at the original loan’s rate is included in the allowance for credit losses.

TDRs that subsequently defaulted

There were 15 residential mortgage loans that had been restructured in a TDR during the previous 12 months and have subsequently defaulted in the first quarter of 2013. The total recorded investment of these loans was $4 million.

Credit quality indicators

Our credit strategy is to focus on investment grade names to support cross-selling opportunities and avoid single name/industry concentrations. Each customer is assigned an internal credit rating which is mapped to an external rating agency grade equivalent based upon a number of dimensions which are continually evaluated and may change over time.

The following tables set forth information about credit quality indicators.

Commercial loan portfolio

Commercial loan portfolio – Credit risk profile by creditworthiness category
	Commercial				Commercial real estate				Financial institutions
(in millions)	March 31, 2013		Dec. 31, 2012		March 31, 2013		Dec. 31, 2012		March 31, 2013		Dec 31, 2012
Investment grade	$	1,110	$	1,064	$	1,493	$	1,289	$	12,128	$	9,935
Noninvestment grade	370		353		381		451		1,656		1,353
Total	$	1,480	$	1,417	$	1,874	$	1,740	$	13,784	$	11,288

The commercial loan portfolio is divided into investment grade and non-investment grade categories based on rating criteria largely consistent with those of the public rating agencies. Each customer in the portfolio is assigned an internal credit rating. These internal credit ratings are generally consistent with the ratings categories of the public rating agencies. Customers with ratings consistent with BBB- (S&P)/Baa3 (Moody’s) or better are considered to be investment grade. Those clients with ratings lower than this threshold are considered to be non-investment grade.

Wealth management loans and mortgages

Wealth management loans and mortgages – Credit risk profile by internally assigned grade
(in millions)	March 31, 2013		Dec. 31, 2012
Wealth management loans:
Investment grade	$	4,583	$	4,597
Noninvestment grade	121		125
Wealth management mortgages	4,287		4,142
Total	$	8,991	$	8,864

Wealth management non-mortgage loans are not typically rated by external rating agencies. A majority of the wealth management loans are secured by the customers’ investment management accounts or custody accounts. Eligible assets pledged for these loans are typically investment-grade, fixed-income securities, equities and/or mutual funds. Internal ratings for this portion of the wealth management portfolio, therefore, would equate to investment-grade external ratings. Wealth management loans are provided to select customers based on the pledge of other types of assets, including business assets, fixed assets or a modest amount of commercial real estate. For the loans collateralized by other assets, the credit quality of the obligor is carefully analyzed, but we do not consider this portfolio of loans to be investment grade.

Credit quality indicators for wealth management mortgages are not correlated to external ratings. Wealth management mortgages are typically loans to high-net-worth individuals, which are secured primarily by residential property. These loans are primarily interest-only adjustable rate mortgages with an average loan-to-value ratio of 63% at origination. In the wealth management portfolio, less than 1% of the mortgages were past due at March 31, 2013.

At March 31, 2013, the private wealth mortgage portfolio was comprised of the following geographic concentrations: New York - 22%; California - 20%; Massachusetts - 16%; Florida - 8%; and other - 34%.

Other residential mortgages

The other residential mortgage portfolio primarily consists of 1-4 family residential mortgage loans and totaled $1,570 million at March 31, 2013 and $1,632 million at Dec. 31, 2012. These loans are not typically correlated to external ratings. Included in this portfolio at March 31, 2013 are $480 million of mortgage loans purchased in 2005, 2006 and the first quarter of 2007 that are predominantly prime mortgage loans, with a small portion of Alt-A loans. As of March 31, 2013, the purchased loans in this portfolio had a weighted-average loan-to-value ratio of 75% at origination and 23% of these loans were at least 60 days delinquent. The properties securing the prime and Alt-A mortgage loans were located (in order of concentration) in California, Florida, Virginia, Maryland and the tri-state area (New York, New Jersey and Connecticut).

Overdrafts

Overdrafts primarily relate to custody and securities clearance clients and totaled $5,319 million at March 31, 2013 and $5,298 million at Dec. 31, 2012. Overdrafts occur on a daily basis in the custody and securities clearance business and are generally repaid within two business days.

Margin loans

We had $13,242 million of secured margin loans on our balance sheet at March 31, 2013 compared with $13,397 million at Dec. 31, 2012. Margin loans are collateralized with marketable securities and borrowers are required to maintain a daily collateral margin in excess of 100% of the value of the loan. We have rarely suffered a loss on these types of loans and do not allocate any of our allowance for credit losses to margin loans.

Other loans

Other loans primarily includes loans to consumers that are fully collateralized with equities, mutual funds and fixed income securities, as well as bankers’ acceptances.

Reverse repurchase agreements

Reverse repurchase agreements are transactions fully collateralized with high-quality liquid securities. These transactions carry minimal credit risk and therefore are not allocated an allowance for credit losses.

Acquisitions and dispositions

Acquisitions

We sometimes structure our acquisitions with both an initial payment and later contingent payments tied to post-closing revenue or income growth. For acquisitions completed prior to Jan. 1, 2009, we record the fair value of contingent payments as an additional cost of the entity acquired in the period that the payment becomes probable. For acquisitions completed after Jan. 1, 2009, subsequent changes in the fair value of a contingent consideration liability are recorded through the income statement. Contingent payments totaled $4 million in the first quarter of 2013.

At March 31, 2013, we were potentially obligated to pay additional consideration which, using reasonable assumptions for the performance of the acquired companies and joint ventures based on contractual agreements, could range from $11 million to $24 million over the next two years.

Acquisitions in 2012

On Oct 1, 2012, BNY Mellon acquired the remaining 50% interest of the WestLB Mellon Asset Management joint venture for cash of $22 million. We later renamed the unit Meriten Investment Management GmbH (“Meriten”). We are obligated to pay, upon occurrence of certain events, contingent additional consideration of up to $13 million. Goodwill related to this acquisition, including the fair value of the contingent additional consideration, totaled $70 million and is included in our Investment Management business. This goodwill is not deductible for tax purposes. Customer relationship intangible assets related to this acquisition are included in our Investment Management business, with a life of eight years, and totaled $23 million.

Temporarily impaired securities

At March 31, 2013, substantially all of the unrealized losses on the investment securities portfolio were attributable to credit spreads widening since purchase, and interest rate movements. We do not intend to sell these securities and it is not more likely than not that we will have to sell.

The following tables show the aggregate related fair value of investments with a continuous unrealized loss position for less than 12 months and those that have been in a continuous unrealized loss position for 12 months or more.

Other-than-temporary impairment

We routinely conduct periodic reviews of all securities using economic models to identify and evaluate each investment security to determine whether OTTI has occurred. Various inputs to the economic models are used to determine if an unrealized loss on securities is other-than-temporary. For example, the most significant inputs related to non-agency RMBS are:

• Default rate - the number of mortgage loans expected to go into default over the life of the transaction, which is driven by the roll rate of loans in each performance bucket that will ultimately migrate to default; and

• Severity - the loss expected to be realized when a loan defaults.

To determine if an unrealized loss is other-than-temporary, we project total estimated defaults of the underlying assets (mortgages) and multiply that calculated amount by an estimate of realizable value upon sale of these assets in the marketplace (severity) in order to determine the projected collateral loss. We also evaluate the current credit enhancement underlying the bond to determine the impact on cash flows. If we determine that a given security will be subject to a write-down or loss, we record the expected credit loss as a charge to earnings.

In addition, we have estimated the expected loss by taking into account observed performance of the underlying securities, industry studies, market forecasts, as well as our view of the economic outlook affecting collateral.

The table below shows the projected weighted-average default rates and loss severities for the 2007, 2006 and late 2005 non-agency RMBS and the securities previously held in the Grantor Trust we established in connection with the restructuring of our investment securities portfolio in 2009, at March 31, 2013 and Dec. 31, 2012.

[1] ASC 815 permits the netting of derivative receivables and derivative payables under legally enforceable master netting agreements and permits the netting of cash collateral.

As previously disclosed, on Nov. 10, 2009 BNY Mellon filed a petition with the U.S. Tax Court challenging the IRS’ disallowance of certain foreign tax credits claimed for the 2001 and 2002 tax years. Trial was held from April 16 to May 17, 2012. On Feb. 11, 2013, BNY Mellon received an adverse decision from the U.S. Tax Court.  We continue to believe the tax treatment of the transaction was correct and will appeal the Court’s decision. As a result of the ruling and in accordance with the accounting for uncertain tax positions under ASC 740, BNY Mellon recorded a tax charge of $854 million in the first quarter of 2013.

Our total tax reserves as of March 31, 2013 were $1,050 million compared with $340 million at Dec. 31, 2012. If these tax reserves were unnecessary, $1,050 million would affect the effective tax rate in future periods. We recognize accrued interest and penalties, if applicable, related to income taxes in income tax expense. Included in the balance sheet at March 31, 2013 is accrued interest, where applicable, of $323 million. The additional tax expense related to interest for the three months endedMarch 31, 2013 was $289 million compared with $3 million for the three months endedMarch 31, 2012.

It is reasonably possible the total reserve for uncertain tax positions could decrease within the next 12 months by an amount up to $72 million as a result of adjustments related to tax years that are still subject to examination.

Our federal income tax returns are closed to examination for all periods through 2002. The years 2003 through 2006 remain open to examination. The years 2007 and 2008 are closed for further examination, however one matter is before the Internal Revenue Service (“IRS”) appeals. Our New York State and New York City income tax returns are closed to examination through 2010. Our UK income tax returns are closed to examination through 2008.

Fair Value Disclosures [Abstract]

Fair Value Option

Fair value option

ASC 825 provides an option to elect fair value as an alternative measurement for selected financial assets, financial liabilities, unrecognized firm commitments and written loan commitments.

The following table presents the assets and liabilities, by type, of consolidated investment management funds recorded at fair value. 

Assets and liabilities of consolidated investment management funds, at fair value
(in millions)	March 31, 2013		Dec. 31, 2012
Assets of consolidated investment management funds:
Trading assets	$	10,400	$	10,961
Other assets	836		520
Total assets of consolidated investment management funds	$	11,236	$	11,481
Liabilities of consolidated investment management funds:

Other liabilities	34		29
Total liabilities of consolidated investment management funds	$	9,942	$	10,181

BNY Mellon values assets in consolidated CLOs using observable market prices observed from the secondary loan market. The returns to the note holders are solely dependent on the assets and accordingly equal the value of those assets. Mark-to-market valuation best reflects the limited interest BNY Mellon has in the economic performance of the consolidated CLOs. Changes in the values of assets and liabilities are reflected in the income statement as investment income of consolidated investment management funds.

We have elected the fair value option on $240 million of long-term debt in connection with ASC 810. At March 31, 2013, the fair value of this long-term debt was $341 million. The long-term debt is valued using observable market inputs and is included in Level 2 of the ASC 820 hierarchy.

The following table presents the changes in fair value of the long-term debt included in foreign exchange and other trading revenue in the consolidated income statement.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments

Derivative instruments

We use derivatives to manage exposure to market risk including interest rate risk, equity price risk and foreign currency risk, as well as credit risk. Our trading activities are focused on acting as a market-maker for our customers and facilitating customer trades. In addition, we periodically manage positions for our own account. Positions managed for our own account are immaterial to our foreign exchange and other trading revenue and to our overall results of operations.

The notional amounts for derivative financial instruments express the dollar volume of the transactions; however, credit risk is much smaller. We perform credit reviews and enter into netting agreements to minimize the credit risk of derivative financial instruments. We enter into offsetting positions to reduce exposure to foreign currency, interest rate and equity price risk.

Use of derivative financial instruments involves reliance on counterparties. Failure of a counterparty to honor its obligation under a derivative contract is a risk we assume whenever we engage in a derivative contract. There were no counterparty default losses in the first quarter of 2013. Counterparty default losses were less than $1 million in the first quarter of 2012.

Hedging derivatives

We utilize interest rate swap agreements to manage our exposure to interest rate fluctuations. For hedges of available-for-sale investment securities, deposits and long-term debt, the hedge documentation specifies the terms of the hedged items and the interest rate swaps and indicates that the derivative is hedging a fixed rate item and is a fair value hedge, that the hedge exposure is to the changes in the fair value of the hedged item due to changes in benchmark interest rates, and that the strategy is to eliminate fair value variability by converting fixed-rate interest payments to LIBOR.

The available-for-sale investment securities hedged consist of sovereign debt and U.S. Treasury bonds that had original maturities of 30 years or less at initial purchase. The swaps on the sovereign debt and U.S. Treasury bonds are not callable. All of these securities are hedged with “pay fixed rate, receive variable rate” swaps of similar maturity, repricing and fixed rate coupon. At March 31, 2013, $5.9 billion face amount of securities were hedged with interest rate swaps that had notional values of $6.1 billion.

The hedged fixed rate deposits have original maturities of approximately ten years and are not callable. These deposits are hedged with “receive fixed rate, pay variable” rate swaps of similar maturity, repricing and fixed rate coupon. The swaps are not callable. At March 31, 2013, $10 million face amount of deposits were hedged with interest rate swaps that had notional values of $10 million.

The fixed rate long-term debt instruments hedged generally have original maturities of five to 30 years. We issue both callable and non-callable debt. The non-callable debt is hedged with simple interest rate swaps similar to those described for deposits. Callable debt is hedged with callable swaps where the call dates of the swaps exactly match the call dates of the debt. At March 31, 2013, $14 billion par value of debt was hedged with interest rate swaps that had notional values of $14 billion.

In addition, we enter into foreign exchange hedges. We use forward foreign exchange contracts with maturities of nine months or less to hedge our British Pound, Euro, Hong Kong Dollar, Indian Rupee and Singapore Dollar foreign exchange exposure with respect to foreign currency forecasted revenue and expense transactions in entities that have the U.S. dollar as their functional currency. As of March 31, 2013, the hedged forecasted foreign currency transactions and designated forward foreign exchange contract hedges were $139 million (notional), with a pre-tax gain of less than $1 million recorded in accumulated other comprehensive income. This gain will be reclassified to income or expense over the next nine months.

We use forward foreign exchange contracts with remaining maturities of nine months or less as hedges against our foreign exchange exposure to Australian Dollar, Euro, Swedish Krona, British Pound, Danish Krone, Norwegian Krone and Japanese Yen with respect to interest-bearing deposits with banks and their associated forecasted interest revenue. These hedges are designated as cash flow hedges. These hedges are effected such that their maturities and notional values match those of the deposits with banks. As of March 31, 2013, the hedged interest-bearing deposits with banks and their designated forward foreign exchange contract hedges were $6.9 billion (notional), with a pre-tax gain of less than $1 million recorded in accumulated other comprehensive income. This gain will be reclassified to net interest revenue over the next nine months.

Forward foreign exchange contracts are also used to hedge the value of our net investments in foreign subsidiaries. These forward foreign exchange contracts have maturities of less than two years. The derivatives employed are designated as hedges of changes in value of our foreign investments due to exchange rates. Changes in the value of the forward foreign exchange contracts offset the changes in value of the foreign investments due to changes in foreign exchange rates. The change in fair market value of these forward foreign exchange contracts is deferred and reported within accumulated translation adjustments in shareholders’ equity, net of tax. At March 31, 2013, forward foreign exchange contracts with notional amounts totaling $5.2 billion were designated as hedges.

In addition to forward foreign exchange contracts, we also designate non-derivative financial instruments as hedges of our net investments in foreign subsidiaries. Those non-derivative financial instruments designated as hedges of our net investments in foreign subsidiaries were all long-term liabilities of BNY Mellon in various currencies, and, at March 31, 2013, had a combined U.S. dollar equivalent value of $500 million.

Trading activities (including trading derivatives)

We manage trading risk through a system of position limits, a VaR methodology based on Monte Carlo simulations, stop loss advisory triggers, and other market sensitivity measures. Risk is monitored and reported to senior management by a separate unit on a daily basis. Based on certain assumptions, the VaR methodology is designed to capture the potential overnight pre-tax dollar loss from adverse changes in fair values of all trading positions. The calculation assumes a one-day holding period for most instruments, utilizes a 99% confidence level, and incorporates the non-linear characteristics of options. The VaR model is one of several statistical models used to develop economic capital results, which is allocated to lines of business for computing risk-adjusted performance.

As the VaR methodology does not evaluate risk attributable to extraordinary financial, economic or other occurrences, the risk assessment process includes a number of stress scenarios based upon the risk factors in the portfolio and management’s assessment of market conditions. Additional stress scenarios based upon historic market events are also performed. Stress tests, by their design, incorporate the impact of reduced liquidity and the breakdown of observed correlations. The results of these stress tests are reviewed weekly with senior management.

Revenue from foreign exchange and other trading included the following:

Foreign exchange and other trading revenue
(in millions)	1Q13		4Q12		1Q12
Foreign exchange	$	149	$	106	$	136
Other trading revenue:
Fixed income	8		25		47
Equity/other	4		8		8
Total other trading revenue	12		33		55
Total	$	161	$	139	$	191

Foreign exchange includes income from purchasing and selling foreign currencies and currency forwards, futures and options. Fixed income reflects results from futures and forward contracts, interest rate swaps, structured foreign currency swaps, options, and fixed income securities. Equity/Other primarily includes revenue from equity securities and equity derivatives.

Counterparty credit risk and collateral

We assess credit risk of our counterparties through regular examination of their financial statements, confidential communication with the management of those counterparties and regular monitoring of publicly available credit rating information. This and other information is used to develop proprietary credit rating metrics used to assess credit quality.

Collateral requirements are determined after a comprehensive review of the credit quality of each counterparty. Collateral is generally held or pledged in the form of cash or highly liquid government securities. Collateral requirements are monitored and adjusted daily.

Additional disclosures concerning derivative financial instruments are provided in Note 15 of the Notes to Consolidated Financial Statements.

Disclosure of contingent features in over-the-counter (“OTC”) derivative instruments

Certain OTC derivative contracts and/or collateral agreements of The Bank of New York Mellon, our largest banking subsidiary and the subsidiary through which BNY Mellon enters into the substantial majority of all of its OTC derivative contracts and/or collateral agreements, contain provisions that may require us to take certain actions if The Bank of New York Mellon’s public debt rating fell to a certain level. Early termination provisions, or “close-out” agreements, in those contracts could trigger immediate payment of outstanding contracts that are in net liability positions. Certain collateral agreements would require The Bank of New York Mellon to immediately post additional collateral to cover some or all of The Bank of New York Mellon’s liabilities to a counterparty.

The following table shows the fair value of contracts falling under early termination provisions that were in net liability positions as of March 31, 2013 for three key ratings triggers:

If The Bank of New York Mellon’s rating was changed to (Moody’s/S&P)	Potential close-out exposures (fair value) (a)
A3/A-		$	824	million
Baa2/BBB		$	993	million
Bal/BB+		$	2,010	million

(a) The change between rating categories is incremental, not cumulative.

Additionally, if The Bank of New York Mellon’s debt rating had fallen below investment grade on March 31, 2013, existing collateral arrangements would have required us to have posted an additional $576 million of collateral.

Offsetting assets and liabilities

The following tables present derivative instruments and financial instruments that are either subject to an enforceable netting agreement or offset by collateral arrangements. There were no derivative instruments or financial instruments subject to a netting agreement for which we are not currently netting.

Restructuring Charges [Abstract]

Restructuring Charges

Restructuring charges

The aggregate restructuring charge is included in the merger and integration, litigation and restructuring charges expense category on the income statement and reported in the Other segment as restructuring charges are corporate initiatives and not directly related to the operating performance of the businesses. Severance payments are primarily paid over the salary continuance period in accordance with the separation plan.

Operational excellence initiatives

In 2011, we announced our operational excellence initiatives which include an expense reduction initiative impacting approximately 1,500 positions, as well as additional initiatives to transform operations, technology and corporate services that will increase productivity and reduce the growth rate of expenses. We recorded a pre-tax restructuring charge of $107 million related to the operational excellence initiatives in 2011. In the first quarter of 2013, we recorded a net charge of $5 million reflecting additional severance charges. The following table presents the activity in the restructuring reserve related to the operational excellence initiatives through March 31, 2013.
