Accounting Policies [Abstract]
Summary of significant accounting and reporting polices	Summary of significant accounting and reporting policies In this Annual Report, 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. Nature of operations BNY Mellon is a global leader in providing a broad range of financial products and services in domestic and international markets. Through our three principal business segments, Securities Services, Market and Wealth Services and Investment and Wealth Management, we serve institutions, corporations and high-net-worth individuals. See Note 24 for the primary products and services of our lines of business and other information. 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. In the opinion of management, all adjustments necessary for a fair presentation of financial position, results of operations and cash flows for the periods presented have been made. 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. Our most significant estimates pertain to our allowance for credit losses, goodwill and other intangibles and litigation and regulatory contingencies. 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. Foreign currency translation Assets and liabilities denominated in foreign currencies are translated to U.S. dollars at the rate of exchange on the balance sheet date. Transaction gains and losses are included in the income statement. Translation gains and losses on investments in foreign entities with functional currencies that are not the U.S. dollar are recorded as foreign currency translation adjustments in other comprehensive income (“OCI”). Revenue and expense transactions are translated at the applicable daily rate or the weighted average monthly exchange rate when applying the daily rate is not practical. Acquired businesses The income statement and balance sheet include results of acquired businesses accounted for under the acquisition method of accounting pursuant to Accounting Standards Codification (“ASC”) 805, Business Combinations, and equity investments from the dates of acquisition. Contingent purchase consideration is measured at its fair value and recorded on the purchase date. Any subsequent changes in the fair value of a contingent consideration liability are recorded through the income statement. Consolidation We evaluate an entity for possible consolidation in accordance with ASC 810, Consolidation . We first determine whether or not we have variable interests in the entity, which are investments or other interests that absorb portions of an entity’s expected losses or receive portions of the entity’s expected returns. Our variable interests may include decision-maker or service provider fees, direct and indirect investments and investments made by related parties, including related parties under common control. If it is determined that we do not have a variable interest in the entity, no further analysis is required and the entity is not consolidated. If we hold a variable interest in the entity, further analysis is performed to determine if the entity is a variable interest entity (“VIE”) or a voting model entity (“VME”). We consider the underlying facts and circumstances of individual entities when assessing whether or not an entity is a VIE. An entity is determined to be a VIE if the equity investors: • do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support; or • lack one or more of the following characteristics of a controlling financial interest: • the power, through voting rights or similar rights, to direct the activities of an entity that most significantly impact the entity’s economic performance; • the obligation to absorb the expected losses of the entity; and • the right to receive the expected residual returns of the entity. We reconsider and reassess whether or not we are the primary beneficiary of a VIE when governing documents or contractual arrangements are changed that would reallocate the obligation to absorb expected losses or receive expected residual returns between BNY Mellon and the other investors. This could occur when BNY Mellon disposes of any portion of its variable interests in the VIE, when we acquire additional variable interests in the VIE, when additional variable interests are issued to other investors or when other investors liquidate their variable interest in the VIE. We consolidate a VIE if it is determined that we have a controlling financial interest in the entity. We have a controlling financial interest in a VIE when we have both (1) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (2) the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to that VIE. For entities that do not meet the definition of a VIE, the entity is considered a VME. We consolidate these entities if we can exert control over the financial and operating policies of an investee, which can occur if we have a 50% or more voting interest in the entity. See Note 14 for additional disclosures related to our variable interests. Equity method investments, including renewable energy investments Equity investments of less than a majority but at least 20% ownership are accounted for by the equity method and included in other assets. Earnings on these investments are reflected as investment services fees, investment management and performance fees or investment and other revenue, as appropriate, in the period earned. A loss in value of an equity investment that is determined to be other-than-temporary is recognized by reducing the carrying value of the equity investment to its fair value. Renewable energy investment projects through limited liability companies are accounted for using the equity method of accounting. The hypothetical liquidation at book value (“HLBV”) methodology is used to determine the pre-tax loss that is recognized in each period. HLBV estimates the liquidation value at the beginning and end of each period, with the difference recognized as the amount of loss under the equity method. The pre-tax losses are reported in investment and other revenue on the income statement. The corresponding tax benefits and credits are recorded as a reduction to provision for income taxes on the income statement. See Note 8 for the amount of our renewable energy investments. Below are our most significant equity method investments, other than the investments in renewable energy. Equity method investments at Dec. 31, 2021 (dollars in millions) Percentage ownership Book value CIBC Mellon Global Securities Services Company (“CIBC Mellon”) 50 % $ 687 Siguler Guff 20 % $ 252 Restricted cash and securities Cash and securities may be segregated under federal and other regulatory requirements and consists of excess client funds held by our broker-dealer entities. Restricted cash is included in interest-bearing deposits with banks on the balance sheet and with cash and due from banks when reconciling the beginning and end-of-period balances on the consolidated statement of cash flows. Securities purchased under resale agreements and securities sold under repurchase agreements Securities purchased under resale agreements and securities sold under repurchase agreements are accounted for as collateralized financings. Generally, these agreements are recorded at the amounts at which the securities will be subsequently resold or repurchased, plus accrued interest. Securities purchased under resale agreements are fully collateralized with high-quality liquid securities. Collateral requirements are monitored and additional collateral is received or provided, as required. As such, these transactions carry minimal credit risk and are generally not allocated an allowance for credit losses. Where an enforceable netting agreement exists, resale and repurchase agreements executed with the same counterparty and the same maturity date are reported on a net basis on the balance sheet. Securities – Debt Debt securities are classified as available-for-sale, held-to-maturity or trading securities when they are purchased. Debt securities are classified as available-for-sale securities when we intend to hold the securities for an indefinite period of time or when the securities may be used for tactical asset/liability purposes and may be sold from time to time to effectively manage interest rate exposure, prepayment risk and liquidity needs. Debt securities are classified as held-to-maturity securities when we intend and have the ability to hold them until maturity. Debt securities are classified as trading securities when our intention is to resell the securities. Available-for-sale securities are measured at fair value. The difference between fair value and amortized cost representing unrealized gains or losses on assets classified as available-for-sale is recorded net of tax as an addition to, or deduction from, OCI, unless an expected credit loss is recognized. Realized gains and losses on sales of available-for-sale securities are reported in investment and other revenue on the income statement. The cost of debt securities sold is determined on a specific identification method. Held-to-maturity securities are measured at amortized cost, which includes expected credit loss, if any. The accounting policy for estimating credit losses related to available-for-sale and held-to-maturity debt securities changed beginning in the first quarter of 2020 as a result of the adoption of ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments . The Company’s policy for recognition of expected credit losses for securities available-for-sale and securities held-to-maturity is contained within “Allowance for credit losses – Securities – Debt” and “Allowance for credit losses – Other” below. Trading securities are measured at fair value and included in trading assets on the balance sheet. Trading revenue includes both realized and unrealized gains and losses. The liability incurred on short-sale transactions, representing the obligation to deliver securities, is included in trading liabilities at fair value. Income on securities purchased is adjusted for amortization of premium and accretion of discount on a level yield basis, generally over their contractual life. For debt securities that are beneficial interests in securitized financial assets and are not high credit quality, ASC 325, Investments – Other , provides that cash flows be discounted at the current yield used to accrete the beneficial interest. A credit loss is recognized when there is an adverse change in expected cash flows. If we intend to sell the security or it is more likely than not that we will be required to sell the security prior to recovery of its cost basis, the security is written down to fair value and the credit and non-credit components of the unrealized loss are recognized in earnings and subsequently accreted to interest income on an effective yield basis over the life of the security. Subsequent increases in the fair value of the security after the write-down are included in OCI. Securities – Equity Investments in equity securities that do not result in consolidation and are not accounted for under the equity method are measured at fair value with changes in the fair value recognized through earnings, unless one of two available exceptions applies. The first exception, a scope exception, allows Federal Reserve Bank stock, Federal Home Loan Bank stock and exchange memberships to remain accounted for at cost, less impairment. The second practicability exception is an election available for equity investments that do not have readily determinable fair values. For certain investments where the Company has chosen the practicability exception, such investments are accounted for in other assets on the balance sheet at cost adjusted for impairment, if any, plus or minus observable price changes in orderly transactions for an identical or similar investment of the same issuer with any such changes reflected in investment and other revenue. Equity securities with readily determinable fair values are classified in trading assets with changes in fair value reflected in other trading revenue, which is included in investment and other revenue in the consolidated income statement. Loans Loans are reported at amortized cost, net of any unearned income and deferred fees and costs. Certain loan origination and upfront commitment fees, as well as certain direct loan origination and commitment costs, are deferred and amortized as a yield adjustment over the lives of the related loans. Loans held for sale are carried at the lower of cost or fair value. Troubled debt restructurings/loan modifications A modified loan is considered a troubled debt restructuring (“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. Credit losses related to TDRs are accounted for under an individual evaluation methodology (see “Allowance for credit losses” below). Credit losses for anticipated TDRs are generally accounted for similarly to TDRs and are identified when there is a reasonable expectation that a TDR will be executed with the borrower and when we expect the modification to affect the timing or amount of payments and/or the payment term. Due to the coronavirus pandemic, there have been two forms of relief provided for classifying loans as TDRs: The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) and the Interagency Guidance (as defined below). Financial institutions may account for eligible loan modifications either under the CARES Act or the Interagency Guidance. The Company has elected to apply both the CARES Act and the Interagency Guidance, as applicable, in providing borrowers with loan modification relief in response to the coronavirus pandemic. The CARES Act, which became law on March 27, 2020, provides that financial institutions may, subject to certain conditions, elect to temporarily suspend the U.S. GAAP requirements with respect to loan modifications related to the coronavirus pandemic that were current as of Dec. 31, 2019 and that would otherwise be identified and treated as TDRs. On Dec. 27, 2020, the Consolidated Appropriations Act, 2021 was signed into law and extends the period established by the CARES Act under which consideration of TDR identification and accounting triggered by effects of the coronavirus pandemic are suspended. That extension period ended on Jan. 1, 2022. Various banking regulators issued guidance in the April 7, 2020 “Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (revised)” (“Interagency Guidance”) on loan modification treatment pursuant to which financial institutions can apply the U.S. GAAP requirements for loan modifications. In accordance with this guidance, a loan modification is not considered a TDR if the modification is related to the coronavirus pandemic, the borrower had been current when the modification program was implemented, and the modification includes payment deferrals for not more than six months. Nonperforming assets Commercial loans are placed on nonaccrual status when principal or interest is past due 90 days or more, or when there is reasonable doubt that interest or principal will be collected. When a first or second lien residential mortgage loan reaches 90 days delinquent, it is subject to an individual evaluation of credit loss and placed on nonaccrual status. When a loan is placed on nonaccrual status, previously accrued and uncollected interest is reversed against current period interest revenue. Interest receipts on nonaccrual loans are recognized as interest revenue or are applied to principal when we believe the ultimate collectability of principal is in doubt. Nonaccrual loans generally are restored to an accrual basis when principal and interest become current and remain current for a specified period. “Allowance for credit losses” below provides additional information regarding the individual evaluation of credit losses for nonperforming loans. Allowance for credit losses The accounting policy for estimating credit losses related to financial assets measured at amortized cost, including loans and lending-related commitments, changed beginning in the first quarter of 2020 as a result of the adoption of ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments . This ASU also included targeted amendments with respect to credit losses for available-for-sale debt securities. The accounting policy for determining the allowances has been identified as a “critical accounting estimate” as it requires us to make numerous complex and subjective estimates and assumptions relating to amounts which are judgmental and inherently uncertain. Credit quality is monitored by management and is reflected within the allowance for credit losses. The allowance represents management’s estimate of expected credit losses over the expected contractual life of the financial instruments as of the balance sheet date. The allowance methodology is designed to provide procedural discipline in assessing the appropriateness of the allowance. A quantitative methodology and qualitative framework is used to estimate the allowance for credit losses. The qualitative framework is described in further detail within “Allowance for credit losses – Other” below. The quantitative component of our estimate uses models and methodologies that categorize financial assets based on product type, collateral type, and other credit trends and risk characteristics, including relevant information about past events, current conditions and reasonable and supportable forecasts of future economic conditions that affect the collectability of the recorded amounts. The allowance may be determined using various methods, including discounted cash flow methods, loss-rate methods, probability of default methods or other methods that we determine to be appropriate. We estimate our expected credit losses using the probability of default method for the majority of our financial assets. We measure expected credit losses of financial assets on a collective (pool) basis when similar risk characteristics exist. For a financial asset that does not share risk characteristics with other assets, expected credit losses are measured based on an individual evaluation method. In our estimate, with the exception of our small home equity line of credit portfolio, available-for-sale debt securities, and individually evaluated financial assets, we utilize a multi-scenario macroeconomic forecast which includes a weighting of three scenarios: a baseline and upside and downside scenarios and allows us to develop our estimate using a wide span of economic variables. Our baseline scenario reflects a view on likely performance of each global region and the other two scenarios are designed relative to the baseline scenario. This approach incorporates a reasonable and supportable forecast period spanning the life of the asset, and this period includes both an initial estimated economic outlook component as well as a reversion component for each economic input variable. The length of each of the two components depends on the underlying financial instrument, scenario and underlying economic input variable. In general, the initial economic outlook period for each economic input variable under each scenario ranges between several months and two years. The speed at which the scenario-specific forecasts revert to long-term historical mean is based on observed historical patterns of mean reversion at the economic variable input level that are reflected in our model parameter estimates. Certain macroeconomic variables such as unemployment or home prices take longer to revert after a contraction, though specific recovery times are scenario-specific. Reversion will usually take longer the further away the scenario-specific forecast is from the historical mean. On a quarterly basis, within a developed governance structure, we update these scenarios for current economic conditions and may adjust the scenario weighting based on our economic outlook. Allowance for credit losses – Loans and lending-related commitments The allowance for credit losses on loans is presented as a valuation allowance to loans, and the allowance for credit losses on lending-related commitments is recorded in other liabilities. The components of the allowance for credit losses on loans and lending-related commitments consist of the following three elements: • a pooled allowance component for higher risk-rated and pass-rated commercial and institutional credits and loans secured by commercial real estate; • a pooled allowance component for residential mortgage loans; and • an asset-specific allowance component involving individually evaluated credits of $1 million or greater. The first element, a pooled allowance component for higher risk-rated and pass-rated commercial and institutional credits and loans secured by commercial real estate, is based on our expected credit loss model using the probability of default method, which has been adjusted for the forecast of economic conditions. Individual credit analyses are performed on such loans before being assigned a credit rating. Segmentation is established based on risk characteristics of the loans and how risk is monitored. In estimating the terms of the exposures and resulting effect on the measurement of expected credit loss, we consider the impact of potential prepayments as well as the effect of borrower extension options. Borrower ratings are reviewed at least annually and are mapped to third-party databases, including rating agency and default and recovery databases, to support ongoing consistency and validity. Higher risk-rated loans and lending-related commitments are reviewed quarterly. For the higher-risk rated and pass-rated commercial and institutional credits, the loss expected in each loan incorporates the borrower’s credit rating, facility rating and maturity. The loss given default, derived from the facility rating, incorporates a recovery expectation, and for unfunded lending exposures, an estimate of the use of the facility at default (usage given default). The borrower’s probability of default is derived from the associated credit rating. The probability of default and the loss given default are applied to the estimated facility amount at default to determine the quantitative component of the allowance. For each of the different parameters, specific credit models are developed for each segment of our portfolio, including commercial loans and lease financing, financial institutions and other. We use both internal and external data in the development of these parameters. For loans secured by commercial real estate, a separate modeled approach is used that considers collateral specific data and loan maturity, as well as commercial real estate market factors by geographical region and property type under different macroeconomic scenarios. A statistical method is used to simulate the property value and income of each property, and to estimate the probability of default, loss given default and expected credit loss for each loan. The model outputs are established by using a baseline, upside and downside macroeconomic scenario to generate projected property values and incomes. The second element, a pooled allowance component for residential mortgage loans, is determined by first segregating our mortgage pools into two categories: (i) our wealth management mortgages and (ii) our legacy mortgage portfolio disclosed as other residential mortgages. We then apply models to each portfolio to predict prepayments, default rates and loss severity. We consider historical loss experience and use a loan-level, multi-period default model which further segments each portfolio by product type, including first lien fixed rate mortgages, first lien adjustable rate mortgages, second lien mortgages and interest-only mortgages. We calculate the mortgage loss up to loan contractual maturity and embed a reasonable and supportable forecast and macroeconomic variable inputs which are described above. 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 limited internal data. Our legacy mortgage portfolio and home equity line of credit portfolios represent small sub-segments of our mortgage loans. The third element, individually evaluated credits, is based on individual analysis of loans of $1 million and greater which no longer share the risk characteristics with other loans. Factors we consider in measuring the extent of expected credit loss include the payment status, collateral value, the borrower’s financial condition, guarantor support, the probability of collecting scheduled principal and interest payments when due, anticipated modifications of payment structure or term for troubled borrowers, and recoveries if they can be reasonably estimated. We measure the expected credit loss as the difference between the amortized cost basis in the loan and the present value of the expected future cash flows from the borrower which is generally discounted at the loan’s effective interest rate, or the fair value of the collateral, if the loan is collateral dependent. We generally consider nonperforming loans as well as loans that have been or are anticipated to be modified and classified under a troubled debt restructuring for individual evaluation given the risk characteristics of such loans. Allowance for credit losses – Securities – Debt When estimating expected credit losses, we segment our available-for-sale and held-to-maturity debt securities portfolios by major asset class. This is influenced by whether the security is structured or non-structured (i.e., direct obligation), as well as the issuer type. For available-for-sale debt securities with an unrealized loss at the balance sheet date, if we determine that a credit loss exists, the amount is recognized as an allowance for credit losses in securities – available-for-sale, with a corresponding adjustment to the provision for credit losses. We evaluate credit losses at the individual security level and do not recognize credit losses if the fair value exceeds amortized cost, and if we determine that a credit loss exists, we limit the recognition of the loss to the difference between fair value and amortized cost. In our determination of whether an expected credit loss exists, we routinely conduct periodic reviews and examine various quantitative and qualitative factors that are unique to each portfolio, including the severity of the unrealized loss position, agency rating, credit enhancement, cash flow deterioration and other factors. The measurement of an expected credit loss is then based on the best estimate of the present value of cash flows to be collected from the debt security. Generally, cash flows are discounted at the effective interest rate implicit in the debt security. Changes to the present value of cash flows due to the passage of time are recognized within the allowance for credit losses. We estimate expected credit losses for held-to-maturity debt securities using a similar methodology as described in the first allowance element within “Allowance for credit losses – Loans and lending-related commitments” above. The allowance for credit losses on held-to-maturity debt securities is recorded in securities – held-to-maturity. The components of the credit loss calculation for each major portfolio or asset class include a probability of default and loss given default and their values depend on the forecast behavior of variables in the macroeconomic environment. For structured debt securities, we estimated expected credit losses at the individual security level and use a cash flow model to project principal losses. Generally, cash flows are discounted at the effective interest rate implicit in the debt security. The difference is reflected in the allowance for credit losses, and changes to the present value of cash flows due to the passage of time are recognized within the allowance for credit losses. We currently do not require an estimate of expected credit losses to be measured and recorded for U.S. Treasury securities, agency debt securities, and other debt securities that meet certain conditions that are based on a combination of factors such as guarantees, credit ratings and other credit quality factors. These assets are monitored within our established governance structure on a recurring basis to determine if any changes are warranted. Allowance for credit losses – Other financial instruments We also estimate expected credit losses associated with margin loans, reverse repurchase agreements, security lending indemnifications, and deposits with third-party financial institutions using a similar risk rating-based modeling approach as described in the first allowance element within “Allowance for credit losses – Loans and lending-related commitments” above. The allowance for credit losses on reverse repurchase agreements is recorded in federal funds sold and securities purchased under resale agreements; the allowance for credit losses on securities lending indemnifications is recorded in other liabilities and the allowance for credit losses on deposits with third-party financial institutions is recorded in cash and due from banks or interest-bearing deposits with banks. Our reverse repurchase agreements are short term and subject to continuous over-collateralization by our counterparties and timely collateral replenishment, when necessary. As a result, we estimate the expected credit loss related to the uncollateralized portion of the asset at the balance sheet date, if any, and when there is a reasonable expectation that the counterparty will not replenish the collateral in compliance with the terms of the repurchase agreement. This method is also applied to margin lending arrangements and securities lending indemnifications. Allowance for credit losses – Other We do not apply our credit loss measurement methodologies to accrued interest receivable balances related to our loan, debt securities and deposits with third-party financial institution assets given our nonaccrual policy that requires charge-off of interest receivable when deemed uncollectible. Accrued interest receivable related to these instruments, along with other interest-bearing instruments, is included on the consolidated balance sheet. Accrued interest receivable related to each major loan class is disclosed within our credit quality disclosure in Note 5. Our policy for credit losses related to purchased financial assets requires an evaluation to be performed prior to the effective purchase date to determine if more than an insignificant decline in credit quality has occurred during the period between the origination and purchase date, or, in the case of debt securities, the period between the issuance and purchase date. If we purchase a financial asset with more than insignificant deterioration in credit quality, the measurement of expected credit loss is performed using the methodologies described above, and the credit loss is recorded as an allowance for credit losses on the purchase date.

Accounting Policies [Abstract]
Accounting changes and new accounting guidance	Accounting changes and new accounting guidance In order to combine items of a similar nature within total revenue and to simplify our income statement presentation, in 2021, we made the following reporting changes. The reclassifications had no impact on consolidated total revenue or total revenue for the business segments. Prior periods were reclassified to be comparable with the current period presentation. • Other trading revenue was reclassified from foreign exchange and other trading revenue to investment and other revenue. • Foreign exchange and other trading revenue was renamed foreign exchange revenue. • The impact of foreign currency remeasurement was reclassified from investment and other revenue to foreign exchange revenue. • Income (loss) from consolidated investment management funds was reclassified to investment and other revenue. • Investment and other revenue was reclassified from fee revenue and is reported separately and net securities gains (losses) was combined with investment and other revenue. In addition, the assets and liabilities of consolidated investment management funds were reclassified to other assets and other liabilities, respectively, on the consolidated balance sheet. The reclassifications had no impact on total assets or total liabilities. Prior periods were reclassified to be comparable with the current period presentation. The table below summarizes the effects of the reclassifications on the consolidated income statement. Consolidated income statement reclassifications Year ended Dec. 31, (in millions) 2020 2019 Before reclassifications Foreign exchange and other trading revenue $ 789 $ 654 Total fee revenue $ 12,714 $ 13,236 Investment and other income $ 184 $ 968 Net securities gains (losses) $ 33 $ (18) Income from consolidated investment management funds $ 84 $ 56 After reclassifications Foreign exchange revenue $ 774 $ 564 Total fee revenue $ 12,515 $ 12,178 Investment and other revenue $ 316 $ 1,096 The table below summarizes the effects of the reclassifications on the consolidated balance sheet.

(b) Includes gross unrealized gains of $455 million and gross unrealized losses of $75 million recorded in accumulated other comprehensive income related to securities that were transferred from available-for-sale to held-to-maturity. The unrealized gains are primarily related to U.S. Treasury securities, agency RMBS and agency commercial MBS. The unrealized losses are primarily related to U.S. Treasury securities and agency RMBS. The unrealized gains and losses will be amortized into net interest revenue over the contractual lives of the securities.

The allowance for credit loss primarily relates to CLOs. (b) Includes gross unrealized gains of $75 million and gross unrealized losses of $44 million recorded in accumulated other comprehensive income related to securities that were transferred from available-for-sale to held-to-maturity. The unrealized gains and losses are primarily related to agency RMBS and will be amortized into net interest revenue over the contractual lives of the securities. The following table presents the realized gains, losses and impairments, on a gross basis.

In 2020, agency commercial MBS with an aggregate amortized cost of $448 million and fair value of $501 million were transferred from available-for-sale securities to held-to-maturity securities to reduce the impact of changes in interest rates on accumulated other comprehensive income. Allowance for credit losses – Securities The allowance for credit losses related to securities was $10 million at Dec. 31, 2021 and $11 million at Dec. 31, 2020, and primarily relates to the available-for-sale CLO portfolio. Credit quality indicators – Securities At Dec. 31, 2021, the gross unrealized losses on the securities portfolio were primarily attributable to an increase in credit spreads from the date of purchase, and for certain securities that were transferred from available-for-sale to held-to-maturity, an increase in interest rates through the date they were transferred. Specifically, $75 million of the unrealized losses at Dec. 31, 2021 and $44 million at Dec. 31, 2020 reflected in the tables below relate to certain securities that were previously transferred from available-for-sale to held-to-maturity. The unrealized losses will be amortized into net interest revenue over the contractual lives of the securities. The transfer created a new cost basis for the securities. As a result, if these securities have experienced unrealized losses since the date of transfer, the corresponding fair value and unrealized losses would be reflected in the held-to-maturity securities portfolio in the following tables. We do not intend to sell these securities, and it is not more likely than not that we will have to sell these securities. The following tables show the aggregate fair value of available-for-sale securities 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 without an allowance for credit losses.

The unrealized losses are primarily related to agency RMBS and will be amortized into net interest revenue over the contractual lives of the securities. There were no gross unrealized losses for less than 12 months. The following tables show the credit quality of the held-to-maturity securities. We have included certain credit ratings information because the information can indicate the degree of credit risk to which we are exposed. Significant changes in ratings classifications could indicate increased credit risk for us and could be accompanied by an increase in the allowance for credit losses and/or a reduction in the fair value of our securities portfolio.

Pledged assets At Dec. 31, 2021, BNY Mellon had pledged assets of $144 billion, including $112 billion pledged as collateral for potential borrowings at the Federal Reserve Discount Window and $7 billion pledged as collateral for borrowing at the Federal Home Loan Bank. The components of the assets pledged at Dec. 31, 2021 included $126 billion of securities, $12 billion of loans, $5 billion of trading assets and $1 billion of interest-bearing deposits with banks. If there has been no borrowing at the Federal Reserve Discount Window, the Federal Reserve generally allows banks to freely move assets in and out of their pledged assets account to sell or repledge the assets for other purposes. BNY Mellon regularly moves assets in and out of its pledged assets account at the Federal Reserve. At Dec. 31, 2020, BNY Mellon had pledged assets of $141 billion, including $113 billion pledged as collateral for potential borrowing at the Federal Reserve Discount Window and $5 billion pledged as collateral for borrowing at the Federal Home Loan Bank. The components of the assets pledged at Dec. 31, 2020 included $124 billion of securities, $11 billion of loans, $6 billion of trading assets and less than $1 billion of interest-bearing deposits with banks. At Dec. 31, 2021 and Dec. 31, 2020, pledged assets included $24 billion and $18 billion, respectively, for which the recipients were permitted to sell or repledge the assets delivered. We also obtain securities as collateral, including receipts under resale agreements, securities borrowed, derivative contracts and custody agreements, on terms which permit us to sell or repledge the securities to others. At Dec. 31, 2021 and Dec. 31, 2020, the market value of the securities received that can be sold or repledged was $122 billion and $121 billion, respectively. We routinely sell or repledge these securities through delivery to third parties. As of Dec. 31, 2021 and Dec. 31, 2020, the market value of securities collateral sold or repledged was $78 billion and $84 billion, respectively. Restricted cash and securities

The prior period was revised to be comparable. (b) Net of unearned income of $240 million at Dec. 31, 2021 and $274 million at Dec. 31, 2020 primarily related to lease financings. We disclose information related to our loans and asset quality by the class of financing receivable in the following tables. Allowance for credit losses On Jan. 1, 2020, we adopted ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments . Activity in the allowance for credit losses on loans and lending-related commitments is presented below. This does not include activity in the allowance for credit losses related to other financial instruments, including cash and due from banks, interest-bearing deposits with banks, federal funds sold and securities purchased under resale agreements, held-to-maturity securities, available-for-sale securities and accounts receivable. In 2019, the allowance for loan losses and lending-related commitments was accounted for under ASC 450, Contingencies , to absorb losses inherent in the loan portfolio as of the balance sheet date, also referred to as the incurred loss methodology. Key elements of our incurred loss methodology included a quantitative assessment for higher risk-rated credits, impaired credits and residential mortgage loans, as well as a qualitative assessment based on internal and environmental risk factors. This methodology differed from the estimate of expected credit losses in 2020 and 2021 primarily in that it was based on historical loss experience and did not include an estimate of credit losses using a reasonable and supportable forecast methodology.

See Note 1 for additional details on the CARES Act, Consolidated Appropriations Act of 2021 and Interagency Guidance. Financial institutions may account for eligible loan modifications either under the CARES Act or the Interagency Guidance. The Company elected to apply both the CARES Act and the Interagency Guidance, as applicable, in providing borrowers with loan modification relief in response to the coronavirus pandemic. We modified loans of $104 million in 2021 and $404 million in 2020. Nearly all of the modifications were short-term loan payment forbearances or modified principal and/or interest payments. These loans were primarily Credit quality indicators Our credit strategy is to focus on investment-grade clients that are active users of our non-credit services. Each customer is assigned an internal credit rating, which is mapped to an external rating agency grade equivalent, if possible, based upon a number of dimensions, which are continually evaluated and may change over time.

Overdrafts occur on a daily basis primarily in the custody and securities clearance business and are generally repaid within two Commercial loans The commercial loan portfolio is divided into investment grade and non-investment grade categories based on the assigned internal credit ratings, which are generally consistent with those 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. Commercial real estate Our income-producing 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 also include construction and renovation facilities. Financial institutions Financial institution exposures are high quality, with 96% of the exposures meeting the investment grade equivalent criteria of our internal credit rating classification at Dec. 31, 2021. In addition, 66% of the financial institutions exposure is secured. For example, securities industry clients and asset managers often borrow against marketable securities held in custody. The exposure to financial institutions is generally short term, with 87% expiring within one year. Wealth management loans Wealth management 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 loan 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. For the loans collateralized by other assets, the credit quality of the obligor is carefully analyzed, but we do not consider this portion of wealth management loan portfolio to be investment grade. Wealth management mortgages 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 a weighted-average loan-to-value ratio of 61% at origination. Delinquency rate is a key indicator of credit quality in the wealth management portfolio. At Dec. 31, 2021, less than 1% of the mortgages were past due. At Dec. 31, 2021, the wealth management mortgage portfolio consisted of the following geographic concentrations: California – 21%; New York – 16%; Florida – 9%; Massachusetts – 9%; and other – 45%. Lease financings At Dec. 31, 2021, the lease financings portfolio consisted of exposures backed by well-diversified assets, primarily large-ticket transportation equipment and real estate. The largest components of our lease residual value exposure were to aircraft and freight-related rail cars. Assets are both domestic and foreign-based, with primary concentrations in Germany and the U.S. Other residential mortgages The other residential mortgage portfolio primarily consists of 1-4 family residential mortgage loans and totaled $299 million at Dec. 31, 2021 and $389 million at Dec. 31, 2020. These loans are not typically correlated to external ratings. Overdrafts Overdrafts primarily relate to custody and securities clearance clients and totaled $3.1 billion at Dec. 31, 2021 and $2.7 billion Dec. 31, 2020. Overdrafts occur on a daily basis and are generally repaid within two Other loans Other loans primarily include loans to consumers that are fully collateralized with equities, mutual funds and fixed-income securities. Margin loans We had $22.5 billion of secured margin loans at Dec. 31, 2021, compared with $15.4 billion at Dec. 31, 2020. 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. Capital call financing Capital call financing includes loans to private equity funds that are secured by the fund investors’ capital commitments and the funds’ right to call capital.

Revenue from Contract with Customer [Abstract]
Contract revenue	Contract revenue Fee and other revenue in the Securities Services, Market and Wealth Services and Investment and Wealth Management business segments is primarily variable, based on levels of assets under custody and/or administration (“AUC/A”), assets under management (“AUM”) and the level of client-driven transactions, as specified in fee schedules. Investment services fees are based primarily on the market value of AUC/A; client accounts, balances and the volume of transactions; securities lending volume and spreads; and fees for other services. Certain fees based on the market value of assets are calculated in arrears on a monthly or quarterly basis. Investment services fees also include transaction-based fees, which are driven by customer actions and are delivered at a point-in-time. These transaction-based fees are generally recognized on trade date. Other contractual investment services fees are driven by the amount of AUC/A or the number of accounts or securities positions and are billed on a monthly or quarterly basis. Substantially all services within the Securities Services and Market and Wealth Services business segments are provided over time. Revenue on these services is recognized using the time elapsed method, equal to the expected invoice amount, which typically represents the value provided to the customer for our performance completed to date. Investment management fees are dependent on the overall level and mix of AUM. The management fees, expressed in basis points, are charged for managing those assets. Management fees are typically subject to fee schedules based on the overall level of assets managed and products in which those assets are invested. Investment management fee revenue also includes transactional- and account-based fees. These fees, along with distribution and servicing fees, are recognized when the services have been completed. Clients are generally billed for services performed on a monthly or quarterly basis. Performance fees are generally calculated as a percentage of the applicable portfolio’s performance in excess of a benchmark index or a peer group’s performance. Performance fees are recognized at the end of the measurement period when they are determinable. See Note 24 for additional information on our principal business segments, Securities Services, Market and Wealth Services and Investment and Wealth Management, and the primary services provided. Disaggregation of contract revenue Contract revenue is included in fee and other revenue on the consolidated income statement. The following tables present fee and other revenue related to contracts with customers, disaggregated by type of fee revenue, for each business segment. Business segment data has been determined on an internal management basis of accounting, rather than GAAP which is used for consolidated financial reporting.

(c) The Investment and Wealth Management business segment is net of income attributable to noncontrolling interests related to consolidated investment management funds of $26 million in 2019. Contract balances Our clients are billed based on fee schedules that are agreed upon in each customer contract. Receivables from customers were $2.5 billion at Dec. 31, 2021 and $2.4 billion at Dec. 31, 2020. Contract assets represent accrued revenues that have not yet been billed to the customers due to certain contractual terms other than the passage of time and were $42 million at Dec. 31, 2021 and $32 million at Dec. 31, 2020. Accrued revenues recorded as contract assets are usually billed on an annual basis. Both receivables from customers and contract assets are included in other assets on the consolidated balance sheet. Contract liabilities represent payments received in advance of providing services under certain contracts and were $163 million at Dec. 31, 2021 and $167 million at Dec. 31, 2020. Contract liabilities are included in other liabilities on the consolidated balance sheet. Revenue recognized in 2021 relating to contract liabilities as of Dec. 31, 2020 was $113 million. Changes in contract assets and liabilities primarily relate to either party’s performance under the contracts. Contract costs Incremental costs for obtaining contracts that are deemed recoverable are capitalized as contract costs. Such costs result from the payment of sales incentives, primarily in the Wealth Management business, and totaled $64 million at Dec. 31, 2021 and $73 million at Dec. 31, 2020. Capitalized sales incentives are amortized based on the transfer of goods or services to which the assets relate and typically average nine years. The amortization of capitalized sales incentives, which is primarily included in staff expense on the consolidated income statement, totaled $20 million in 2021, $21 million in 2020 and $22 million in 2019. Costs to fulfill a contract are capitalized when they relate directly to an existing contract or a specific anticipated contract, generate or enhance resources that will be used to fulfill performance obligations, and are recoverable. Such costs generally represent set-up costs, which include any direct cost incurred at the inception of a contract which enables the fulfillment of the performance obligation, and totaled $23 million at Dec. 31, 2021 and $15 million at Dec. 31, 2020. These capitalized costs are amortized on a straight-line basis over the expected contract period, which generally ranges from seven Unsatisfied performance obligations We do not have any unsatisfied performance obligations other than those that are subject to a practical expedient election under ASC 606, Revenue From Contracts With Customers . The practical expedient election applies to (i) contracts with an original expected length of one year or less, and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.

We believe it is more likely than not that the benefit from these foreign tax credits will not be realized. Accordingly, we have recorded a valuation allowance of $83 million. We believe it is more likely than not that we will fully realize our remaining deferred tax assets. This conclusion is based on historical financial results and profit forecasts. As of Dec. 31, 2021, we had approximately $1 billion of earnings attributable to foreign subsidiaries that have been permanently reinvested abroad and for which no local distribution tax provision has been recorded. If these earnings were to be repatriated, the estimated tax liability as of Dec. 31, 2021 would be up to $120 million. The statutory federal income tax rate is reconciled to our effective income tax rate below: Effective tax rate Year ended Dec. 31, 2021 2020 2019 Federal rate 21.0 % 21.0 % 21.0 % State and local income taxes, net of federal income tax benefit 2.3 1.8 0.9 Foreign operations 0.8 1.5 2.4 Tax credits (4.6) (4.1) (3.2) Tax-exempt income (1.0) (1.0) (0.7) Federal Deposit Insurance Corporation (“FDIC”) assessment 0.3 0.3 0.2 Stock compensation (0.1) — (0.4) Other – net 0.2 (0.7) (0.2) Effective tax rate 18.9 % 18.8 % 20.0 % Unrecognized tax positions (in millions) 2021 2020 2019 Beginning balance at Jan. 1, – gross $ 119 $ 173 $ 103 Prior period tax positions: Increases 18 45 60 Decreases (3) (14) (3) Current period tax positions 9 15 17 Settlements (5) (100) (4) Ending balance at Dec. 31, – gross $ 138 $ 119 $ 173 Our total tax reserves as of Dec. 31, 2021 were $138 million compared with $119 million at Dec. 31, 2020. If these tax reserves were unnecessary, $138 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 Dec. 31, 2021 is accrued interest, where applicable, of $39 million. The additional tax expense related to interest for the year ended Dec. 31, 2021 was $12 million, compared with $15 million for the year ended Dec. 31, 2020. It is reasonably possible the total reserve for uncertain tax positions could decrease within the next 12 months by approximately $5 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 through 2016. Our New York State

Securitizations And Variable Interest Entities Disclosure [Abstract]
Variable interest entities and securitization	Variable interest entities and securitization We have variable interests in variable interest entities (“VIEs”), which include investments in retail, institutional and alternative investment funds, including CLO structures in which we provide asset management services, some of which are consolidated. We earn management fees from these funds as well as performance fees in certain funds and may also provide start-up capital for new funds. The funds are primarily financed by our customers’ investments in the funds’ equity or debt. Additionally, we invest in qualified affordable housing and renewable energy projects, which are designed to generate a return primarily through the realization of tax credits. The projects, which are structured as limited partnerships and limited liability companies, are also VIEs, but are not consolidated. The following table presents the incremental assets and liabilities included in the consolidated balance sheet as of Dec. 31, 2021 and Dec. 31, 2020. 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 we invested in the VIE.

We have not provided financial or other support that was not otherwise contractually required to be provided to our VIEs. Additionally, creditors of any consolidated VIEs do not have any recourse to the general credit of BNY Mellon. Non-consolidated VIEs As of Dec. 31, 2021 and Dec. 31, 2020, the following assets and liabilities related to the VIEs where we are not the primary beneficiary were included in our consolidated balance sheets and primarily related to accounting for our investments in qualified affordable housing and renewable energy projects.

Stockholders' Equity Note [Abstract]
Shareholders’ equity	Shareholders’ equity Common stock BNY Mellon has 3.5 billion authorized shares of common stock with a par value of $0.01 per share. At Dec. 31, 2021, 804,145,366 shares of common stock were outstanding. Common stock repurchase program In March 2020, we and the other members of the Financial Services Forum announced the temporary suspension of share repurchases until the end of the second quarter of 2020 to preserve capital and liquidity in order to further the objective of using capital and liquidity to support clients and customers. In June 2020, the Federal Reserve announced that it required participating Comprehensive Capital Analysis and Review (“CCAR”) firms, including us, to update and resubmit their capital plans and that, as a result, unless otherwise approved by the Federal Reserve, participating firms were not permitted to conduct open market common stock repurchases in the third quarter of 2020. In September 2020, the Federal Reserve extended the limitation on open market common stock repurchases through the fourth quarter of 2020. During the third and fourth quarters of 2020, participating CCAR firms were also subject to limitations on common stock dividends. In December 2020, the Federal Reserve released the results of the second round of CCAR stress tests and extended the restriction on common stock dividends and open market common share repurchases applicable to participating CCAR firms, including us, to the first quarter of 2021, with certain modifications. In March 2021, the Federal Reserve extended these restrictions through the second quarter of 2021. The temporary restrictions on dividends and share repurchases ended for BNY Mellon after June 30, 2021. After these temporary restrictions were lifted, BNY Mellon continued to be subject to the stress capital buffer framework, which would impose restrictions on capital distributions on an incremental basis if BNY Mellon’s risk-based capital ratios decline into the buffer zone. The Company declared its common stock dividend for the first quarter of 2021 and was authorized during the quarter to conduct open market common share repurchases in an amount up to approximately $625 million under the Federal Reserve’s modified distribution limitation. In June 2021, in connection with the Federal Reserve’s release of the 2021 CCAR stress tests, we announced a share repurchase program approved by our Board of Directors providing for the repurchase of up to $6.0 billion of common shares beginning in the third quarter of 2021 and continuing through the fourth quarter of 2022. This new share repurchase plan replaced all previously authorized share repurchase plans. In July 2021, our Board of Directors approved a 10% increase in the quarterly cash dividend on common stock, from $0.31 to $0.34 per share. Share repurchases may be executed through open market repurchases, in privately negotiated transactions or by other means, including through repurchase plans designed to comply with Rule 10b5-1 and other derivative, accelerated share repurchase and other structured transactions. In 2021, we repurchased 89.7 million common shares at an average price of $50.91 per common share for a total of $4.6 billion. At Dec. 31, 2021, the maximum dollar value of shares that can be purchased under the 2021 share repurchase program, including employee benefit plan repurchases, totaled $2.75 billion. Preferred stock The Parent has 100 million authorized shares of preferred stock with a par value of $0.01 per share.

Holders of the Series D preferred stock are entitled to receive dividends, if declared by the Parent’s Board of Directors, on each June 20 and December 20, to but excluding June 20, 2023; and on each March 20, June 20, September 20 and December 20, from and including June 20, 2023. Holders of the Series F preferred stock are entitled to receive dividends, if declared by the Parent’s Board of Directors, on each March 20 and September 20, to and including Sept. 20, 2026; and on each March 20, June 20, September 20 and December 20, from and including Dec. 20, 2026. Holders of the Series G preferred stock are entitled to receive dividends, if declared by the Parent’s Board of Directors, on each March 20 and September 20.

Holders of the Series I preferred stock are entitled to receive dividends, if declared by the Parent’s Board of Directors, on each March 20, June 20, September 20 and December 20, commencing on March 20, 2022. 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 the Parent 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 (in the case of dividends) or most recently completed dividend period (in the case of repurchases) of the Series A preferred stock or the last preceding dividend period (in the case of dividends) or most recently completed dividend period (in the case of repurchases) of the Series D, Series F, Series G, Series H and Series I preferred stock. All of the outstanding shares of the Series A preferred stock are owned by Mellon Capital IV, a 100% owned financing subsidiary of the Parent, which will pass through any dividend on the Series A preferred stock to the holders of its Normal Preferred Capital Securities. The Parent’s obligations under the trust and other agreements relating to Mellon Capital IV have the effect of providing a full and unconditional guarantee, on a subordinated basis, of payments due on the Normal Preferred Capital Securities. No other subsidiary of the Parent guarantees the securities of Mellon Capital IV. All of the outstanding shares of the Series D, Series F, Series G, Series H and Series I preferred stock are held by the depositary of the depositary shares, which will pass through the applicable portion of any dividend on the Series D, Series F, Series G, Series H and Series I preferred stock to the holders of record of their respective depositary shares. In December 2021, the Parent redeemed all outstanding shares of its Series E preferred stock, 100,000 liquidation preference per share. Deferred fees of approximately $10 million were realized as preferred stock dividends upon redemption. In December 2020, the Parent redeemed all outstanding shares of its Series C preferred stock, 100,000 liquidation preference per share.

Capital adequacy Regulators establish certain levels of capital for bank holding companies (“BHCs”) 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 U.S. bank subsidiaries and BNY Mellon must, among other things, qualify as “well capitalized.” As of Dec. 31, 2021 and Dec. 31, 2020, BNY Mellon and our U.S. bank subsidiaries were “well capitalized.” The regulatory capital ratios of our consolidated and largest bank subsidiary, The Bank of New York Mellon, are shown below. Consolidated and largest bank subsidiary regulatory capital ratios (a) Dec. 31, 2021 2020 Consolidated regulatory capital ratios: Common Equity Tier 1 (“CET1”) ratio 11.2 % 13.1 % Tier 1 capital ratio 14.0 15.8 Total capital ratio 14.9 16.7 Tier 1 leverage ratio 5.5 6.3 Supplementary leverage ratio (“SLR”) (b)(c) 6.6 8.6 The Bank of New York Mellon regulatory capital ratios: CET1 ratio 16.5 % 17.1 % Tier 1 capital ratio 16.5 17.1 Total capital ratio 16.5 17.3 Tier 1 leverage ratio 6.0 6.4 SLR (b) 7.6 8.5 (a) For our CET1, Tier 1 capital and Total capital ratios, our effective capital ratios under U.S. capital rules are the lower of the ratios as calculated under the Standardized and Advanced Approaches. The Tier 1 leverage ratio is based on Tier 1 capital and quarterly average total assets. For BNY Mellon to qualify as “well capitalized,” its Tier 1 capital and Total capital ratios must be at least 6% and 10%, respectively. For The Bank of New York Mellon, our largest bank subsidiary, to qualify as “well capitalized,” its CET1, Tier 1 capital, Total capital and Tier 1 leverage ratios must be at least 6.5%, 8%, 10% and 5%, respectively. (b) The SLR is based on Tier 1 capital and total leverage exposure, which includes certain off-balance sheet exposures. For The Bank of New York Mellon to qualify as “well capitalized,” its SLR must be at least 6%. (c) The consolidated SLR at Dec. 31, 2020 reflects the temporary exclusion of U.S. Treasury securities from the total leverage exposure. The temporary exclusion ceased to apply beginning April 1, 2021. Failure to satisfy regulatory standards, including “well capitalized” status or capital adequacy rules more generally, could result in limitations on our activities and adversely affect our financial condition. If a BHC such as BNY Mellon, or a bank such as The Bank of New York Mellon or BNY Mellon, N.A., fails to satisfy minimum capital requirements or qualify as “adequately capitalized,” regulatory sanctions and limitations will be imposed.

Share-based Payment Arrangement [Abstract]
Stock-based compensation	Stock-based compensation Our Long-Term Incentive Plans provide for the issuance of restricted stock, restricted stock units (“RSUs”) and other stock-based awards, including options, to employees and directors of BNY Mellon. At Dec. 31, 2021, under the Long-Term Incentive Plan approved in April 2019, we may issue 23,481,182 new stock-based awards, all of which may be issued as restricted stock or RSUs. Stock-based compensation expense related to retirement eligibility vesting totaled $64 million in 2021, $43 million in 2020 and $84 million in 2019. Restricted stock, RSUs and Performance share units Restricted stock and RSUs are granted under our long-term incentive plans at no cost to the recipient. These awards are subject to forfeiture until certain restrictions have lapsed, including continued employment, for a specified period. The recipient of a share of restricted stock is entitled to voting rights and generally is entitled to dividends on the common stock. An RSU entitles the recipient to receive a share of common stock after the applicable restrictions lapse. The recipient generally is entitled to receive cash payments equivalent to any dividends paid on the underlying common stock during the period the RSU is outstanding but does not receive voting rights. The fair value of restricted stock and RSUs is equal to the fair market value of our common stock on the date of grant. The expense is recognized over the vesting period, which is generally zero BNY Mellon’s Executive Committee members were granted a target award of 648,973 performance share units (“PSUs”) in 2021, 402,486 in 2020 and 576,855 in 2019. The 2021 Executive Committee PSUs will vest based on two separate and distinct measurements, a performance condition and a market condition split 70% based on return on tangible common shareholders’ equity (“ROTCE”) and 30% on Total Shareholder Return (“TSR”). The TSR portion was valued using a Monte Carlo simulation method, while the ROTCE portion was measured based on the fair market value on the date of grant. Each condition only impacts its applicable portion (70%/30%) of the total PSU award. The performance and market conditions are measured after three years to determine the final percentage of the total PSUs to vest. The final total amount of vested PSUs will be the sum of the two separate and distinct performance and market-based portions of the PSU awards, but will be capped at 150% of the total PSUs awarded. The ultimate payout is subject to the discretion of the Human Resources and Compensation Committee. These awards are classified as equity and the ROTCE portion is marked-to-market to earnings as a result of this discretion. The 2019 and 2020 PSU awards cliff vest in three years with the number of shares that vest determined based on a payout table that references performance conditions related to average revenue growth and average operating margin, both as adjusted and subject to Human Resources and Compensation Committee discretion. These awards are classified as equity and marked-to-market to earnings as a result of this discretion. The following table summarizes our non-vested PSU, restricted stock and RSU activity for 2021. Non-vested PSU, restricted stock and RSU activity Number of shares (a) Weighted-average fair value at Non-vested PSUs, restricted stock and RSUs at Dec. 31, 2020 12,536,899 $ 49.35 Granted 7,557,597 42.67 Vested (4,789,555) 51.00 Forfeited (622,954) 45.24 Non-vested PSUs, restricted stock and RSUs at Dec. 31, 2021 14,681,987 $ 45.55 (a) Includes dividend shares earned on the Executive Committee PSUs and Board of Director’s stock awards. As of Dec. 31, 2021, $281 million of total unrecognized compensation costs related to non-vested PSUs, restricted stock and RSUs is expected to be recognized over a weighted-average period of 2.2 years. The total fair value of restricted stock, RSUs and PSUs that vested was $240 million in 2021, $263 million in 2020 and $278 million in 2019. The actual excess tax (expense) benefit realized for the tax deductions from shares vested totaled $(8) million in 2021, $(4) million in 2020 and $11 million in 2019. The tax benefits were recognized in the provision for income taxes. Subsidiary Long-Term Incentive Plans BNY Mellon also has several subsidiary Long-Term Incentive Plans which have issued restricted subsidiary shares to certain employees. These share awards are subject to forfeiture until certain restrictions have lapsed, including continued employment for a specified period of time. The shares are generally non-voting and non-dividend paying. Once the restrictions lapse, which generally occurs in three instances BNY Mellon has an election to call the shares. Stock options Our Long-Term Incentive Plans provide for the issuance of stock options at fair market value at the date of grant to officers and employees of BNY Mellon. Generally, each option granted is exercisable between one Compensation costs that were charged against income were $1 million in 2021 and less than $1 million in 2020 and 2019. The income tax benefit recognized in the consolidated income statement related to compensation costs was less than $1 million in 2021, 2020 and 2019. A summary of the status of our options as of Dec. 31, 2021, and changes during the year, is presented below: Stock option activity Shares subject Weighted-average Weighted-average remaining contractual term (in years) Balance at Dec. 31, 2020 2,335,238 $ 23.99 0.9 Granted — — Exercised (1,910,185) 24.37 Canceled/Expired (17,148) 27.63 Balance at Dec. 31, 2021 407,905 $ 22.03 0.1 Vested and expected to vest at Dec. 31, 2021 407,905 22.03 0.1 Exercisable at Dec. 31, 2021 407,905 22.03 0.1 Stock options outstanding at Dec. 31, 2021 Options outstanding Options exercisable (a) Range of exercise prices Outstanding Weighted-average remaining contractual life (in years) Weighted-average Exercisable Weighted-average $21 to 31 407,905 0.1 $ 22.03 407,905 $ 22.03 (a) At Dec. 31, 2020 and Dec. 31, 2019, 2,335,238 and 4,143,575 options were exercisable at a weighted-average price per common share of $23.99 and $26.03, respectively.

Retirement Benefits [Abstract]
Employee benefit plans	Employee benefit plans BNY Mellon has defined benefit and/or defined contribution retirement plans and other post-retirement plans providing healthcare benefits. The defined benefit pension plans cover approximately 9,100 U.S. employees and approximately 14,400 non-U.S. employees. BNY Mellon has one qualified and several non-qualified defined benefit pension plans in the U.S. and several pension plans overseas. Effective June 30, 2015, the benefit accruals under the U.S. qualified and non-qualified defined benefit plans were frozen. This change resulted in no additional benefits being earned by participants in those plans based on service or pay after June 30, 2015. These plans were previously closed to new participants effective Dec. 31, 2010. Effective Dec. 31, 2018, the benefit accruals were frozen under our largest foreign plan, which covers certain UK employees. This change resulted in no additional benefits being earned by participants in that plan based on service or pay after Dec. 31, 2018. Most UK employees currently earn benefits only on a defined contribution basis. UK employees impacted by the pension plan freeze began earning benefits on a defined contribution basis on Jan. 1, 2019.

N/A – Not applicable. A number of key assumptions and measurement date values determine pension expense. The key elements include the long-term rate of return on plan assets, the discount rate, the market-related value of plan assets and the price used to value stock in the Employee Stock Ownership Plan (“ESOP”). The discount rate for U.S. pension plans was determined after reviewing equivalent rates obtained by discounting the pension plans’ expected cash flows using various high-quality, long-term corporate bond yield curves. We also reviewed the results of several models that matched bonds to our pension cash flows. After reviewing the various indices and models, we selected a discount rate of 3.03% as of Dec. 31, 2021. The discount rates for foreign pension plans are based on high-quality corporate bond rates in countries that have an active corporate bond market. In those countries with no active corporate bond market, discount rates are based on local government bond rates plus a credit spread. Actuarial gains on the benefit obligation for the domestic and foreign pension plans in 2021 are primarily attributable to increases in discount rates. Actuarial losses on the benefit obligation for the domestic and foreign pension plans in 2020 are primarily attributable to decreases in discount rates.

Assumed healthcare cost trend The assumed healthcare cost trend rate used in determining domestic benefit expense for 2022 is 6.90%, decreasing to 4.04% in 2075 for pre-Medicare costs and 5.65% decreasing to 4.04% in 2075 for Medicare costs. The initial trend rate assumption represents an estimate of short term cost increases based on recent health care marketplace experience, and taking into consideration the cost characteristics of plans available to retirees. Annual increases in national health expenditures have exceeded the general growth in GDP for many years. However, there are practical limitations to how long these trends can continue. It is unrealistic to assume that health care expenditures will be allowed to consume the majority of the economy. Therefore, over the long term we expect that health care costs will be constrained by the public’s ability and willingness to pay the higher cost of health care coverage. This assumption implies that the ultimate trend rate should be related to the expected long-term growth in the economy. Therefore, we assume the ultimate rate to be comprised of real growth in per capita GDP, long-term growth attributable to technology innovations, and the assumed long-term inflation rate. The initial trend is assumed to decrease to this ultimate rate over time. These long-range trend impacts were developed using the Getzen Model of Long-Run Medical Cost Trends. The following benefit payments for the pension and healthcare plans, which reflect expected future service as appropriate, are expected to be paid over the next 10 years: Expected benefit payments (in millions) Domestic Foreign Pension benefits: Year 2022 $ 268 $ 45 2023 276 47 2024 282 47 2025 277 49 2026 275 51 2027-2031 1,326 273 Total pension benefits $ 2,704 $ 512 Healthcare benefits: Year 2022 $ 10 $ — 2023 10 — 2024 10 — 2025 10 — 2026 9 — 2027-2031 39 1 Total healthcare benefits $ 88 $ 1 Plan contributions We expect to make cash contributions to fund our defined benefit pension plans in 2022 of $14 million for the domestic plans and $10 million for the foreign plans. Investment strategy and asset allocation We are responsible for the administration of various employee pension and healthcare post-retirement benefits plans, both domestically and internationally. The domestic plans are administered by BNY Mellon’s Benefits Administration Committee, a named fiduciary. Subject to the following, at all relevant times, BNY Mellon’s Benefits Investment Committee, another named fiduciary to the domestic plans, is responsible for the investment of plan assets. The Benefits Investment Committee’s responsibilities include the investment of all domestic defined benefit plan assets, as well as the determination of investment options offered to participants in all domestic defined contribution plans. The Benefits Investment Committee conducts periodic reviews of investment performance, asset allocation and investment manager suitability. In addition, the Benefits Investment Committee has oversight of the Regional Governance Committees for the foreign defined benefit plans. Our investment objective for U.S. and foreign plans is to maximize total return while maintaining a broadly diversified portfolio for the primary purpose of satisfying obligations for future benefit payments. Our plans are primarily invested in fixed income and equity securities. In general, for the domestic plan’s portfolio, fixed income securities can range from 35% to 100% of plan assets, equity securities and alternative investments can range from 0% to 65% of plan assets and cash equivalents can be held in amounts ranging from 0% to 10% of plan assets. Actual asset allocation within the approved ranges varies from time to time based on economic conditions (both current and forecast), the timing of transitional reallocations and the advice of professional advisors. Our pension assets were invested as follows: Asset allocations Domestic Foreign 2021 2020 2021 2020 Fixed income 60 % 62 % 82 % 82 % Equities 37 36 8 8 Alternative investments 2 2 9 9 Cash 1 — (a) 1 1 Total pension benefits 100 % 100 % 100 % 100 % (a) The allocation percentage is less than 1%. We held no The Bank of New York Mellon Corporation stock in our pension plans at Dec. 31, 2021 and Dec. 31, 2020. Assets of the U.S. postretirement healthcare plan are invested in an insurance contract. Fair value measurement of plan assets In accordance with ASC 715, Compensation – Retirement Benefits , we have established a three-level hierarchy for fair value measurements of its pension plan assets based upon the transparency of inputs to the valuation of an asset as of the measurement date. The valuation hierarchy is consistent with guidance in ASC 820, Fair Value Measurement , which is detailed in Note 20. The following is a description of the valuation methodologies used for assets measured at fair value, as well as the general classification of such assets pursuant to the valuation hierarchy. Cash and currency This category consists primarily of foreign currency balances and is included in Level 1 of the valuation hierarchy. Foreign currency is translated monthly based on current foreign exchange rates. Common and preferred stock and mutual funds These investments include equities and mutual funds and are valued at the closing price reported in the active market in which the individual securities are traded, if available. Common and preferred stock and mutual funds are included in Level 1 of the valuation hierarchy. Collective trust funds Collective trust funds include commingled and U.S. equity funds that have no readily available market quotations. The fair value of the funds is based on the securities in the portfolio, which typically are the amount that the fund might reasonably expect to receive for the securities upon a sale. These funds are valued using observable inputs on either a daily or monthly basis. Collective trust funds are included in Level 2 of the valuation hierarchy. Fixed-income investments Fixed-income investments include U.S. Treasury securities, U.S. government agencies, sovereign government obligations, state and political subdivisions, U.S. corporate bonds, supranational and foreign corporate debt funds. U.S. Treasury and certain sovereign debt securities that are actively traded in highly liquid over-the-counter (“OTC”) markets are valued at the closing price reported in the active market in which the individual security is traded and included as Level 1 of the valuation hierarchy. U.S. government agencies, sovereign government obligations, state and political subdivisions, U.S. corporate bonds, supranational and foreign corporate debt funds are valued based on quoted prices for comparable securities with similar yields and credit ratings. When quoted prices are not available for identical or similar bonds, the bonds are valued using discounted cash flows that maximize observable inputs, such as current yields of similar instruments, but includes adjustments for certain risks that may not be observable, such as credit and liquidity risks. U.S. government agencies, sovereign government obligations, state and political subdivisions, U.S. corporate bonds, supranational and foreign corporate debt funds are primarily included in Level 2 of the valuation hierarchy. Other assets measured at NAV per share, as a practical expedient Other assets measured at NAV, as a practical expedient, include funds of funds, venture capital and partnership interests and other funds. There are no readily available market quotations for these funds. The fair value of the funds of funds is based on NAVs of the funds in the portfolio, which reflects the value of the underlying investments held by the fund, less its liabilities. The fair value of the underlying investments is typically the amount that the fund might reasonably expect to receive upon selling those hard to value or illiquid investments within the portfolios. These funds are either valued on a daily or monthly basis. The fair value of the venture capital and partnership interests is based on the pension plan’s ownership percentage of the fair value of the underlying funds as provided by the fund managers. These funds are typically valued on a quarterly basis. The following tables present the fair value of each major category of plan assets as of Dec. 31, 2021 and Dec. 31, 2020, by captions and by ASC 820, Fair Value Measurement , valuation hierarchy.

Defined contribution plans We sponsor defined contribution plans in the U.S. and in certain non-U.S. locations, all of which are administered in accordance with local laws. The most significant defined contribution plan is The Bank of New York Mellon Corporation 401(k) Savings Plan sponsored by the Company in the U.S. and covers substantially all U.S. employees. Under The Bank of New York Mellon Corporation 401(k) Savings Plan for 2021, the Company matched dollar for dollar participant contributions up to 7% of an employee’s eligible base pay with a monetary limit of $16,000 per participant. In addition, an annual non-elective contribution of $750 was made to participants earning less than $100,000 a year who are credited with at least one year of service in 2021. For 2020 and 2019, the Company matched 100% of the first 4% of an employee’s eligible base pay plus 50% of the next 2% of eligible pay contributed by the participant for a maximum matching contribution of 5%, subject to statutory limits. In addition, annual non-elective contributions equal to 2% of eligible base pay were made in 2020 and 2019. At Dec. 31, 2021 and Dec. 31, 2020, The Bank of New York Mellon Corporation 401(k) Savings Plan owned 9.5 million and 10.8 million shares of our common stock, respectively. The fair value of total assets was $9.4 billion at Dec. 31, 2021 and $8.2 billion at Dec. 31, 2020. We recorded expenses of $258 million in 2021, $249 million in 2020 and $244 million in 2019, primarily for contributions to our defined contribution plans. We also have an ESOP covering certain domestic full-time employees hired on or before July 1, 2008. The ESOP works in conjunction with the defined benefit pension plan. Employees are entitled to the higher of their benefit under the ESOP or such defined benefit pension plan at retirement. Benefits payable under the defined benefit pension plan are offset by the equivalent value of benefits earned under the ESOP. At Dec. 31, 2021 and Dec. 31, 2020, the ESOP owned 4.0 million and 4.3 million shares of our common stock, respectively. The fair value of total ESOP assets was $236 million at Dec. 31, 2021 and $187 million at Dec. 31, 2020. The Company is not permitted to make contributions to the ESOP. The Benefits Investment Committee appointed Fiduciary Counselors, Inc. to serve as the independent fiduciary to (i) make all fiduciary decisions related to the continued prudence of offering the common stock of BNY Mellon or its affiliates as an investment option under the plans, other than plan sponsor decisions, and (ii) select and monitor any actively or passively managed investments of BNY Mellon or its affiliates to be offered to participants as investment options under the plans, excluding self-directed accounts.

Condensed Financial Information Disclosure [Abstract]
Company financial information (Parent Corporation)	Company financial information (Parent Corporation) In connection with our single point of entry resolution strategy, we have established an intermediate holding company (“IHC”) to facilitate the provision of capital and liquidity resources to certain key subsidiaries in the event of material financial distress or failure. In 2017, we entered into a binding support agreement with those key subsidiaries and other related entities that requires the IHC to provide that support. The support agreement requires the Parent to transfer cash and other liquid financial assets to the IHC on an ongoing basis, subject to certain amounts retained by the Parent to meet its near-term cash needs. The Parent’s and the IHC’s obligations under the support agreement are secured. The IHC has provided unsecured subordinated funding notes to the Parent as well as a committed line of credit that allows the Parent to draw funds necessary to service near-term obligations. As a result, during business-as-usual circumstances, the Parent is expected to continue to have access to the funds necessary to pay dividends, repurchase common stock, service its debt and satisfy its other obligations. If our projected liquidity resources deteriorate so severely that resolution of the Parent becomes imminent, the committed line of credit the IHC provided to the Parent will automatically terminate, with all amounts outstanding becoming due and payable, and the support agreement will require the Parent to transfer most of its remaining assets (other than stock in subsidiaries and a cash reserve to fund bankruptcy expenses) to the IHC. As a result, during a period of severe financial stress, the Parent could become unable to meet its debt and payment obligations (including with respect to its securities), causing the Parent to seek protection under bankruptcy laws earlier than it otherwise would have. Our bank subsidiaries are subject to dividend limitations under the federal and state banking laws. Under these statutes, prior regulatory consent is required for dividends in any year that would exceed the bank’s net profits for such year combined with retained net profits for the prior two years. Additionally, such bank subsidiaries may not declare dividends in excess of net profits on hand, as defined, after deducting the amount by which the principal amount of all loans, on which interest is past due for a period of six months or more, exceeds the allowance for credit losses. The payment of dividends also is limited by minimum capital requirements and buffers imposed on banks. As of Dec. 31, 2021, our bank subsidiaries exceeded these requirements. Subsequent to Dec. 31, 2021, our U.S. bank subsidiaries could declare dividends to the Parent of approximately $1.5 billion, without the need for a regulatory waiver. In addition, at Dec. 31, 2021, non-bank subsidiaries of the Parent had liquid assets of approximately $2.3 billion. The bank subsidiaries declared dividends of $2.5 billion in 2021, $1.5 billion in 2020 and $3.2 billion in 2019. The Federal Reserve and the Office of the Comptroller of the Currency have issued additional guidelines that require BHCs and national banks to continually evaluate the level of cash dividends in relation to their respective operating income, capital needs, asset quality and overall financial condition. The Federal Reserve policy with respect to the payment of cash dividends by BHCs provides that, as a matter of prudent banking, a BHC should not maintain a rate of cash dividends unless its net income available to common shareholders has been sufficient to fully fund the dividends, and the prospective rate of earnings retention appears to be consistent with the holding company’s capital needs, asset quality and overall financial condition. The Federal Reserve can also prohibit a dividend if payment would constitute an unsafe or unsound banking practice. In December 2020, the Federal Reserve released the results of the second round of CCAR stress tests and extended the restriction on common stock dividends and open market common stock repurchases applicable to participating CCAR BHCs, including us, to the first quarter of 2021, with certain modifications. In March 2021, the Federal Reserve extended these restrictions through the second quarter of 2021. The temporary restrictions on dividends and share repurchases ended for BNY Mellon after June 30, 2021. After these temporary restrictions were lifted, BNY Mellon continued to be subject to the stress capital buffer framework, which would impose restrictions on capital distributions on an incremental basis if BNY Mellon’s risk-based capital ratios decline into the buffer zone. In June 2021, in connection with the Federal Reserve’s release of the 2021 CCAR stress tests, we announced a share repurchase program approved by our Board of Directors providing for the repurchase of up to $6.0 billion of common stock beginning in the third quarter of 2021 and continuing through the fourth quarter of 2022. This new share repurchase plan replaced all previously authorized share repurchase plans. The Federal Reserve Act limits, and requires collateral for, extensions of credit by our insured subsidiary banks to the Parent and certain of its non-bank affiliates. Also, there are restrictions on the amounts of investments by such banks in stock and other securities of BNY Mellon and such affiliates, and restrictions on the acceptance of their securities as collateral for loans by such banks. Extensions of credit by the banks to each of our affiliates are limited to 10% of such bank’s regulatory capital, and in the aggregate for BNY Mellon and all such affiliates to 20%, and collateral must be between 100% and 130% of the amount of the credit, depending on the type of collateral. In the event of impairment of the capital stock of one of the Parent’s national banks or The Bank of New York Mellon, the Parent, as the banks’ stockholder, could be required to pay such deficiency. The Parent guarantees the committed and uncommitted lines of credit of Pershing LLC and Pershing Limited subsidiaries. The Parent guarantees described above are full and unconditional and contain the standard provisions relating to parent guarantees of subsidiary debt. Additionally, the Parent guarantees or indemnifies obligations of its consolidated subsidiaries as needed. Generally, there are no stated notional amounts included in these indemnifications and the contingencies triggering the obligation for indemnification are not expected to occur. As a result, we are unable to develop an estimate of the maximum payout under these indemnifications. However, we believe the possibility is remote that we will have to make any material payment under these guarantees and indemnifications. The Parent also guaranteed the debt issued by Mellon Funding Corporation, a wholly-owned financing subsidiary of the Company, which was dissolved in 2021. No debt issued by Mellon Funding Corporation was outstanding as of Dec. 31, 2020. Financial data for the Parent for 2020 and 2019 includes Mellon Funding Corporation for financial reporting purposes because of the limited function of this entity and the unconditional guarantee by BNY Mellon of its obligations.

Fair value measurement

Fair Value Disclosures [Abstract]
Fair value measurement	Fair value measurementFair value is defined 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. A three-level hierarchy for fair value measurements is utilized based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. BNY Mellon’s own creditworthiness is considered when valuing liabilities. Fair value 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 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 record financial instruments at fair value. Most derivative contracts are valued using models which are calibrated to observable market data and employ standard market pricing theory for their valuations. Valuation models incorporate counterparty credit risk 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’s own credit spreads, as implied by the credit default swap market. 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 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 A three-level valuation hierarchy is used 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 certain debt and equity securities, derivative financial instruments actively traded on exchanges and highly liquid government bonds. 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 financial instruments whose model inputs are observable in the market or can be corroborated by market-observable data. Examples in this category are MBS, corporate debt securities and OTC derivative contracts. Level 3 : Inputs to the valuation methodology are unobservable and significant to the fair value measurement. 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. Valuation methodology 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 We determine fair value primarily based on pricing sources with reasonable levels of price transparency. 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 U.S. Treasury and certain sovereign debt securities that are actively traded in highly liquid OTC markets, money market funds and exchange-traded equities. If quoted market prices are not available, fair values are primarily determined using pricing models using observable trade data, market data, 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 MBS, state and political subdivisions, certain sovereign debt, corporate bonds and foreign covered bonds. 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. At Dec. 31, 2021, approximately 99% of our securities were valued by pricing sources with reasonable levels of price transparency. The remaining securities were generally valued using observable inputs. Additional disclosures of securities are provided in Note 4. 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. As of Dec. 31, 2021, we have no instruments included in Level 3 of the valuation hierarchy. Derivative financial instruments We classify exchange-traded derivative financial instruments valued using quoted prices in Level 1 of the valuation hierarchy. Examples include exchange-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 models that use as their basis readily observable market parameters, and we classify them in Level 2 of the valuation hierarchy. Such derivative financial instruments include swaps and options, foreign exchange spot and forward contracts 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 may include long-dated swaps and options, where parameters may be unobservable for longer maturities; and certain highly structured products, where correlation risk is unobservable. As of Dec. 31, 2021, we have no Level 3 derivatives. Additional disclosures of derivative instruments are provided in Note 23. Seed capital In our Investment and Wealth Management business segment, we make seed capital investments in certain funds we manage. Seed capital is generally included in other assets on the consolidated balance sheet. When applicable, we value seed capital based on the published NAV of the fund. 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. Interests in securitizations For the interests in securitizations that are classified in trading assets—equity instruments 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. These interests in securitizations matured in 2021. Other assets measured at NAV We hold private equity investments, primarily SBICs, which are compliant with the Volcker Rule. There are no readily available market quotations for these investment partnerships. The fair value of the SBICs is based on our ownership percentage of the fair value of the underlying investments as provided by the partnership managers. These investments are typically valued on a quarterly basis. Our SBIC private equity investments are valued at NAV as a practical expedient for fair value. The following tables present the financial instruments carried at fair value at Dec. 31, 2021 and Dec. 31, 2020, by caption on the consolidated balance sheet and by the three-level valuation hierarchy. 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.

Assets and liabilities measured at fair value on a nonrecurring basis Under certain circumstances, we make adjustments to the fair value of our assets, liabilities and unfunded lending-related commitments, although they are not measured at fair value on an ongoing basis. Examples would be the recording of an impairment of an asset and non-readily marketable equity securities carried at cost with upward or downward adjustments. The following table presents the financial instruments carried on the consolidated balance sheet by caption and level in the fair value hierarchy as of Dec. 31, 2021 and Dec. 31, 2020.

Fair Value Disclosures [Abstract]
Fair value option	Fair value option We elected fair value as an alternative measurement for selected financial assets and liabilities that are not otherwise required to be measured at fair value, including the assets and liabilities of consolidated investment management funds, certain long-term debt and subordinated notes associated with certain equity investments. The following table presents the assets and liabilities of consolidated investment management funds, at fair value. Assets and liabilities of consolidated investment management funds, at fair value Dec. 31, (in millions) 2021 2020 Assets of consolidated investment management funds: Trading assets $ 443 $ 482 Other assets 19 5 Total assets of consolidated investment management funds $ 462 $ 487 Liabilities of consolidated investment management funds: Other liabilities $ 3 $ 3 Total liabilities of consolidated investment management funds $ 3 $ 3 The assets and liabilities of the consolidated investment management funds are included in other assets and other liabilities on the consolidated balance sheet. We value the assets and liabilities of its consolidated investment management funds using quoted prices for identical assets or liabilities in active markets or observable inputs such as quoted prices for similar assets or liabilities. Quoted prices for either identical or similar assets or liabilities in inactive markets may also be used. Accordingly, fair value best reflects the interests BNY Mellon holds in the economic performance of the consolidated investment management funds. Changes in the fair value of the assets and liabilities are recorded as income (loss) from consolidated investment management funds, which is included in investment and other revenue in the consolidated income statement. We elected the fair value option on $240 million of long-term debt. This long-term debt matured in 2021. The fair value of this long-term debt was $400 million at Dec. 31, 2020. The long-term debt was valued using observable market inputs and included in Level 2 of the valuation hierarchy. The following table presents the changes in fair value of long-term debt recorded in other trading revenue, which is included in investment and other revenue in the consolidated income statement.

We elected the fair value option on $15 million of subordinated notes associated with certain equity investments. The fair value of these of subordinated notes was $15 million at Dec. 31, 2021. The subordinated notes were valued using observable market inputs and included in Level 2 of the valuation hierarchy.

Commitments and Contingencies Disclosure [Abstract]
Commitments and contingent liabilities	Commitments and contingent liabilities Off-balance sheet arrangements 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 risks not recognized on the balance sheet. Our off-balance sheet risks are managed and monitored in manners similar to those used for on-balance sheet risks. The following table presents a summary of our off-balance sheet credit risks. Off-balance sheet credit risks Dec. 31, 2021 Dec. 31, 2020 (in millions) Lending commitments $ 46,183 $ 47,577 Standby letters of credit (“SBLC”) (a) 1,971 2,265 Commercial letters of credit 56 60 Securities lending indemnifications (b)(c) 487,298 469,121 (a) Net of participations totaling $128 million at Dec. 31, 2021 and $154 million at Dec. 31, 2020. (b) Excludes the indemnification for securities for which BNY Mellon acts as an agent on behalf of CIBC Mellon clients, which totaled $67 billion at Dec. 31, 2021 and $62 billion at Dec. 31, 2020. (c) Includes cash collateral, invested in indemnified repurchase agreements, held by us as securities lending agent of $48 billion at Dec. 31, 2021 and $41 billion at Dec. 31, 2020. 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 lending 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: $27.1 billion in less than one year, $18.6 billion in one to five years and $516 million over five years. SBLCs principally support obligations of corporate clients and were collateralized with cash and securities of $172 million at Dec. 31, 2021 and $194 million at Dec. 31, 2020. At Dec. 31, 2021, $1.4 billion of the SBLCs will expire within one year, $601 million in one to five years and none over five years. We must recognize, at the inception of an SBLC and foreign and other guarantees, a liability for the fair value of the obligation undertaken in issuing the guarantee. 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 SBLCs and foreign and other guarantees, if any, is included in the allowance for lending-related commitments. 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 Dec. 31, 2021 Dec. 31, 2020 Investment grade 85 % 82 % Non-investment grade 15 % 18 % 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 $56 million at Dec. 31, 2021 and $60 million at Dec. 31, 2020. We expect many of the lending commitments and letters of credit 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. The allowance for lending-related commitments was $45 million at Dec. 31, 2021 and $121 million at Dec. 31, 2020. 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. We typically lend securities with indemnification against borrower default. We generally require the borrower to provide collateral with a minimum 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 $511 billion at Dec. 31, 2021 and $493 billion at Dec. 31, 2020. CIBC Mellon, a joint venture between BNY Mellon and the Canadian Imperial Bank of Commerce (“CIBC”), engages in securities lending activities. CIBC Mellon, BNY Mellon and CIBC jointly and severally indemnify securities lenders against specific types of borrower default. At Dec. 31, 2021 and Dec. 31, 2020, $67 billion and $62 billion, respectively, of borrowings at CIBC Mellon, for which BNY Mellon acts as agent on behalf of CIBC Mellon clients, were secured by collateral of $71 billion and $66 billion, respectively. If, upon a default, a borrower’s collateral was not sufficient to cover its related obligations, certain losses related to the indemnification could be covered by the indemnitors. Unsettled repurchase and reverse repurchase agreements In the normal course of business, we enter into repurchase agreements and reverse repurchase agreements that settle at a future date. In repurchase agreements, BNY Mellon receives cash from and provides securities as collateral to a counterparty at settlement. In reverse repurchase agreements, BNY Mellon advances cash to and receives securities as collateral from the counterparty at settlement. These transactions are recorded on the consolidated balance sheet on the settlement date. At Dec. 31, 2021, we had $2.6 billion of unsettled repurchase agreements and $9.1 billion of unsettled reverse repurchase agreements. Industry concentrations We have significant industry concentrations related to credit exposure at Dec. 31, 2021. The tables below present our credit exposure in the financial institutions and commercial portfolios. Financial institutions portfolio exposure (in billions) Dec. 31, 2021 Loans Unfunded Total exposure Securities industry $ 1.7 $ 17.5 $ 19.2 Asset managers 1.7 7.1 8.8 Banks 5.8 1.5 7.3 Insurance 0.2 3.4 3.6 Government 0.1 0.2 0.3 Other 0.7 0.9 1.6 Total $ 10.2 $ 30.6 $ 40.8 Commercial portfolio exposure (in billions) Dec. 31, 2021 Loans Unfunded Total exposure Manufacturing $ 0.6 $ 3.9 $ 4.5 Energy and utilities 0.4 3.9 4.3 Services and other 1.0 3.2 4.2 Media and telecom 0.1 0.9 1.0 Total $ 2.1 $ 11.9 $ 14.0 Major concentrations in securities lending are primarily to broker-dealers and are generally collateralized with cash and/or securities. Sponsored member repo program BNY Mellon is a sponsoring member in the Fixed Income Clearing Corporation (“FICC”) sponsored member program, where we submit eligible overnight repurchase and reverse repurchase transactions in U.S. Treasury and agency securities (“Sponsored Member Transactions”) between BNY Mellon and our sponsored member clients for novation and clearing through FICC pursuant to the FICC Government Securities Division rulebook (the “FICC Rules”). We also guarantee to FICC the prompt and full payment and performance of our sponsored member clients’ respective obligations under the FICC Rules in connection with such clients’ Sponsored Member Transactions. We minimize our credit exposure under this guaranty by obtaining a security interest in our sponsored member clients’ collateral and rights under Sponsored Member Transactions. See “Offsetting assets and liabilities” in Note 23 for additional information on our repurchase and reverse repurchase agreements. 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 proceedings related 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 Dec. 31, 2021 and Dec. 31, 2020, we have not recorded any material liabilities under these arrangements. Clearing and settlement exchanges We are a noncontrolling equity investor in, and/or member of, several industry clearing or settlement exchanges through which foreign exchange, securities, derivatives or other transactions settle. Certain of these industry clearing and settlement exchanges require their members to guarantee their obligations and liabilities and/or to provide liquidity 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. Any ancillary costs that occur as a result of any mark-to-market loss cannot be quantified. In addition, we also sponsor clients as members on clearing and settlement exchanges and guarantee their obligations. At Dec. 31, 2021 and Dec. 31, 2020, we did not record any material liabilities under these arrangements. Legal proceedings In the ordinary course of business, The Bank of New York Mellon Corporation and its subsidiaries are routinely named as defendants in or made parties to pending and potential legal actions. We also are subject to governmental and regulatory examinations, information-gathering requests, investigations and proceedings (both formal and informal). Claims for significant monetary damages are often asserted in many of these legal actions, while claims for disgorgement, restitution, penalties and/or other remedial actions or sanctions may be sought in governmental and 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, settlements or orders, 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 our results of operations 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, we establish 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. We regularly 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, we do not establish an accrual and the matter continues to be monitored for any developments that would make the loss contingency both probable and reasonably estimable. We believe that our 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 the results of operations in a given period. In addition, if we have the potential to recover a portion of an estimated loss from a third party, we record a receivable up to the amount of the accrual that is probable of recovery. For certain of those matters described here 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 described here where BNY Mellon is able to estimate a reasonably possible loss, the aggregate range of such reasonably possible loss is up to $600 million in excess of the accrued liability (if any) related to those matters. For matters where a reasonably possible loss is denominated in a foreign currency, our estimate is adjusted quarterly based on prevailing exchange rates. We do not consider potential recoveries when estimating reasonably possible losses. The following describes certain judicial, regulatory and arbitration proceedings involving BNY Mellon: Mortgage-Securitization Trusts Proceedings The Bank of New York Mellon has been named as a defendant in a number of legal actions brought by MBS investors alleging that the trustee has expansive duties under the governing agreements, including the duty to investigate and pursue breach of representation and warranty claims against other parties to the MBS transactions. Three actions commenced in December 2014, December 2015 and February 2017 are pending in New York federal court; and four actions commenced in May 2016, September 2021 (two related cases) and October 2021, are pending in New York state court. Matters Related to R. Allen Stanford In late December 2005, Pershing LLC (“Pershing”) became a clearing firm for Stanford Group Co. (“SGC”), a registered broker-dealer that was part of a group of entities ultimately controlled by R. Allen Stanford (“Stanford”). Stanford International Bank, also controlled by Stanford, issued certificates of deposit (“CDs”). Some investors allegedly wired funds from their SGC accounts to purchase CDs. In 2009, the Securities and Exchange Commission charged Stanford with operating a Ponzi scheme in connection with the sale of CDs, and SGC was placed into receivership. Alleged purchasers of CDs have filed two putative class action proceedings against Pershing: one in November 2009 in Texas federal court, and one in May 2016 in New Jersey federal court. On Nov. 5, 2021, the court dismissed the class action filed in New Jersey. Three lawsuits remain against Pershing in Louisiana and New Jersey federal courts, which were filed in January 2010, October 2015 and May 2016. The purchasers allege that Pershing, as SGC’s clearing firm, assisted Stanford in a fraudulent scheme and assert contractual, statutory and common law claims. In March 2019, a group of investors filed a putative class action against The Bank of New York Mellon in New Jersey federal court, making the same allegations as in the prior actions brought against Pershing. On Nov. 12, 2021, the court dismissed the class action against The Bank of New York Mellon. All the cases that have been brought in federal court against Pershing and the case brought against The Bank of New York Mellon have been consolidated in Texas federal court for discovery purposes. In July 2020, after being enjoined from pursuing claims before the Financial Industry Regulatory Authority, Inc. (“FINRA”), an investment firm filed an action against Pershing in Texas federal court. This action has been resolved. Various alleged Stanford CD purchasers asserted similar claims in FINRA arbitration proceedings. Brazilian Postalis Litigation BNY Mellon Servicos Financeiros DTVM S.A. (“DTVM”), a subsidiary that provides asset services in Brazil, acts as administrator for certain investment funds in which a public pension fund for postal workers called Postalis-Instituto de Seguridade Social dos Correios e Telégrafos (“Postalis”) invested. On Aug. 22, 2014, Postalis sued DTVM in Rio de Janeiro, Brazil for losses related to a Postalis fund for which DTVM is administrator. Postalis alleges that DTVM failed to properly perform duties, including to conduct due diligence of and exert control over the manager. On March 12, 2015, Postalis filed a lawsuit in Rio de Janeiro against DTVM and BNY Mellon Administração de Ativos Ltda. (“Ativos”) alleging failure to properly perform duties relating to another fund of which DTVM is administrator and Ativos is manager. On Dec. 14, 2015, Associacão dos Profissionais dos Correios (“ADCAP”), a Brazilian postal workers association, filed a lawsuit in São Paulo against DTVM and other defendants alleging that DTVM improperly contributed to Postalis investment losses. On March 20, 2017, the lawsuit was dismissed without prejudice, and ADCAP appealed. On Aug. 4, 2021, the appellate court overturned the dismissal and sent the lawsuit to a state lower court. On Dec. 17, 2015, Postalis filed three lawsuits in Rio de Janeiro against DTVM and Ativos alleging failure to properly perform duties with respect to investments in several other funds. On May 20, 2021, the court in one of those lawsuits entered a $3 million judgment against DTVM and Ativos. On Aug. 23, 2021, DTVM and Ativos filed an appeal of the May 20 decision. On Feb. 4, 2016, Postalis filed a lawsuit in Brasilia against DTVM, Ativos and BNY Mellon Alocação de Patrimônio Ltda. (“Alocação de Patrimônio”), an investment management subsidiary, alleging failure to properly perform duties and liability for losses with respect to investments in various funds of which the defendants were administrator and/or manager. On Jan. 16, 2018, the Brazilian Federal Prosecution Service (“MPF”) filed a civil lawsuit in São Paulo against DTVM alleging liability for Postalis losses based on alleged failures to properly perform certain duties as administrator to certain funds in which Postalis invested or as controller of Postalis’s own investment portfolio. On April 18, 2018, the court dismissed the lawsuit without prejudice. On Aug. 4, 2021, the appellate court overturned the dismissal and returned the lawsuit to the lower court. In addition, the Tribunal de Contas da União (“TCU”), an administrative tribunal, has initiated three proceedings with the purpose of determining liability for losses to three investment funds administered by DTVM in which Postalis was an investor. On Sept. 9, 2020, TCU rendered a decision in one of the proceedings, finding DTVM and two former Postalis directors jointly and severally liable for approximately $45 million. TCU also imposed on DTVM a fine of approximately $2 million. DTVM has filed an administrative appeal of the decision. On Oct. 4, 2019, Postalis and another pension fund filed a request for arbitration in São Paulo against DTVM and Ativos alleging liability for losses to an investment fund for which DTVM was administrator and Ativos was manager. On March 26, 2021, DTVM and Ativos filed a lawsuit challenging the decision rendered by the Arbitration Court with respect to its jurisdiction over the case. On Oct. 25, 2019, Postalis filed a lawsuit in Rio de Janeiro against DTVM and Alocação de Patrimônio, alleging liability for losses in another fund for which DTVM was administrator and Alocação de Patrimônio and Ativos were managers. On June 19, 2020, a lawsuit was filed in federal court in Rio de Janeiro against DTVM, Postalis, and various other defendants alleging liability against DTVM for certain Postalis losses in an investment fund of which DTVM was administrator. On Feb. 10, 2021, Postalis and another pension fund served DTVM in a lawsuit filed in Rio de Janeiro, alleging liability for losses in another investment fund for which DTVM was administrator and the other defendant was manager. Brazilian Silverado Litigation DTVM acts as administrator for the Fundo de Investimento em Direitos Creditórios Multisetorial Silverado Maximum (“Silverado Maximum Fund”), which invests in commercial credit receivables. On June 2, 2016, the Silverado Maximum Fund sued DTVM in its capacity as administrator, along with Deutsche Bank S.A. - Banco Alemão in its capacity as custodian and Silverado Gestão e Investimentos Ltda. in its capacity as investment manager. The Fund alleges that each of the defendants failed to fulfill its respective duty, and caused losses to the Fund for which the defendants are jointly and severally liable. German Tax Matters German authorities are investigating past “cum/ex” trading, which involved the purchase of equity securities on or shortly before the dividend date, but settled after that date, potentially resulting in an unwarranted refund of withholding tax. German authorities have taken the view that past cum/ex trading may have resulted in tax avoidance or evasion. European subsidiaries of BNY Mellon have been informed by German authorities about investigations into potential cum/ex trading by certain third-party investment funds, where one of the subsidiaries had acquired entities that served as depositary and/or fund manager for those third-party investment funds. We have received information requests from the authorities relating to pre-acquisition activity and are cooperating fully with those requests. In August 2019, the District Court of Bonn ordered that one of these subsidiaries be joined as a secondary party in connection with the prosecution of unrelated individual defendants. Trial commenced in September 2019. In March 2020, the court stated that it would refrain from taking action against the subsidiary in order to expedite the conclusion of the trial. The court convicted the unrelated individual defendants, and determined that the cum/ex trading activities of the relevant third-party investment funds were unlawful. In November and December 2020, we received secondary liability notices from the German tax authorities totaling approximately $150 million related to pre-acquisition activity in various funds for which the entities we acquired were depositary and/or fund manager. We have appealed the notices. In connection with the acquisition of the subject entities, we obtained an indemnity for liabilities from the sellers that we intend to pursue as necessary.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative instruments	Derivative instrumentsWe 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 compliance with the Volcker Rule. 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 and collateral arrangements 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 recorded in 2021. Hedging derivatives We utilize interest rate swap agreements to manage our exposure to interest rate fluctuations. We enter into fair value hedges as an interest rate risk management strategy to reduce fair value variability by converting certain fixed rate interest payments associated with available-for-sale securities and long-term debt to floating interest rates. We also utilize interest rate swaps and forward exchange contracts as cash flow hedges to manage our exposure to interest rate and foreign exchange rate changes. The available-for-sale securities hedged consist of U.S. Treasury, agency and non-agency commercial MBS, sovereign debt/sovereign guaranteed, corporate bonds and foreign covered bonds. At Dec. 31, 2021, $24.4 billion par value of available-for-sale securities were hedged with interest rate swaps designated as fair value hedges that had notional values of $24.5 billion. The fixed rate long-term debt instruments hedged generally have original maturities of five In addition, we utilize forward foreign exchange contracts as hedges to mitigate foreign exchange exposures. We use forward foreign exchange contracts as cash flow hedges to convert certain forecasted non-U.S. dollar revenue and expenses into U.S. dollars. We use forward foreign exchange contracts with maturities of 15 months or less as cash flow hedges to hedge our foreign exchange exposure to currencies such as Indian rupee, British pound, euro, Hong Kong dollar, Polish zloty and Singapore dollar used in revenue and expense transactions for entities that have the U.S. dollar as their functional currency. As of Dec. 31, 2021, the hedged forecasted foreign currency transactions and designated forward foreign exchange contract hedges were $347 million (notional), with a pre-tax gain of $2 million recorded in accumulated OCI. This gain will be reclassified to earnings over the next 12 months. We also utilize forward foreign exchange contracts as fair value hedges of the foreign exchange risk associated with available-for-sale securities. Forward points are designated as an excluded component and amortized into earnings over the hedge period. The unamortized derivative value associated with the excluded component is recognized in accumulated OCI. At Dec. 31, 2021, $141 million par value of available-for-sale securities was hedged with foreign currency forward contracts that had a notional value of $141 million. 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 one year. The derivatives employed are designated as hedges of changes in value of our foreign investments due to exchange rates. The change in fair market value of these forward foreign exchange contracts is reported within foreign currency translation adjustments in shareholders’ equity, net of tax. At Dec. 31, 2021, forward foreign exchange contracts with notional amounts totaling $9.9 billion were designated as net investment hedges. From time to time, we also designate non-derivative financial instruments as hedges of our net investments in foreign subsidiaries. At Dec. 31, 2021, there were no non-derivative financial instruments hedging our net investments in foreign subsidiaries. The following table presents the pre-tax gains (losses) related to our fair value and cash flow hedging activities recognized in the consolidated income statement.

(b) For derivative transactions settled at clearing organizations, cash collateral exchanged is deemed a settlement of the derivative each day. The settlement reduces the gross fair value of derivative assets and liabilities and results in a corresponding decrease in the effect of master netting agreements, with no impact to the consolidated balance sheet. (c) The fair value of asset derivatives and liability derivatives not designated as hedging instruments is recorded as trading assets and trading liabilities, respectively, on the consolidated balance sheet. (d) Fair values are on a gross basis, before consideration of master netting agreements, as required by ASC 815, Derivatives and Hedging. (e) Effect of master netting agreements includes cash collateral received and paid of $1,424 million and $786 million, respectively, at Dec. 31, 2021, and $1,552 million and $1,051 million, respectively, at Dec. 31, 2020. Trading activities (including trading derivatives) Our trading activities are focused on acting as a market-maker for our customers, facilitating customer trades and risk-mitigating economic hedging in compliance with the Volcker Rule. The change in the fair value of the derivatives utilized in our trading activities is recorded in foreign exchange revenue and investment and other revenue on the consolidated income statement. The following table presents our foreign exchange revenue and other trading revenue. Foreign exchange revenue and other trading revenue Year ended Dec. 31, (in millions) 2021 2020 2019 Foreign exchange revenue $ 799 $ 774 (a) $ 564 (a) Other trading revenue 6 13 (a) 77 (a) (a) In 2021, we reclassified certain items within total revenue on the consolidated income statement and reclassified prior periods to be comparable with the current period presentation. See Note 2 for additional information. Foreign exchange revenue includes income from purchasing and selling foreign currencies, currency forwards, futures and options as well as foreign currency remeasurement. Other trading revenue reflects results from trading in cash instruments, including fixed income and equity securities, and trading and economic hedging activity with non-foreign exchange derivatives. We also use derivative financial instruments as risk-mitigating economic hedges, which are not formally designated as accounting hedges. This includes hedging the foreign currency, interest rate or market risks inherent in some of our balance sheet exposures, such as seed capital investments and deposits, as well as certain investment management fee revenue streams. We also use total return swaps to economically hedge obligations arising from the Company’s deferred compensation plan whereby the participants defer compensation and earn a return linked to the performance of investments they select. The gains or losses on these total return swaps are recorded in staff expense on the consolidated income statement and were gains of $35 million in 2021, $22 million in 2020 and $36 million in 2019. We manage trading risk through a system of position limits, a value-at-risk (“VaR”) methodology based on historical simulation and other market sensitivity measures. Risk is monitored and reported to senior management by a separate unit, independent from trading, 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 VaR methodology does not evaluate risk attributable to extraordinary financial, economic or other occurrences. As a result, 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 historical market events are also performed. Stress tests may incorporate the impact of reduced market liquidity and the breakdown of historically observed correlations and extreme scenarios. VaR and other statistical measures, stress testing and sensitivity analysis are incorporated into other risk management materials. Counterparty credit risk and collateral We assess the 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 and/or highly liquid government securities. Collateral requirements are monitored and adjusted daily. Additional disclosures concerning derivative financial instruments are provided in Note 20. Disclosure of contingent features in OTC derivative instruments Certain OTC derivative contracts and/or collateral agreements contain credit risk-contingent features triggered upon a rating downgrade in which the counterparty has the right to request additional collateral or the right to terminate the contracts in a net liability position. The following table shows the aggregate fair value of OTC derivative contracts in net liability positions that contained credit risk-contingent features and the value of collateral that has been posted. Dec. 31, 2021 Dec. 31, 2020 (in millions) Aggregate fair value of OTC derivatives in net liability positions (a) $ 3,606 $ 5,235 Collateral posted $ 5,388 $ 5,568 (a) Before consideration of cash collateral. The aggregate fair value of OTC derivative contracts containing credit risk-contingent features can fluctuate from quarter to quarter due to changes in market conditions, composition of counterparty trades, new business or changes to the contingent features. The Bank of New York Mellon, our largest banking subsidiary, enters into the substantial majority of our OTC derivative contracts and/or collateral agreements. As such, the contingent features may be triggered if The Bank of New York Mellon’s long-term issuer rating were downgraded. The following table shows the fair value of contracts falling under early termination provisions that were in net liability positions for three key ratings triggers. Potential close-out exposures (fair value) (a) Dec. 31, 2021 Dec. 31, 2020 (in millions) If The Bank of New York Mellon’s rating changed to: (b) A3/A- $ 56 $ 79 Baa2/BBB $ 563 $ 813 Ba1/BB+ $ 1,778 $ 2,859 (a) The amounts represent potential total close-out values if The Bank of New York Mellon’s long-term issuer rating were to immediately drop to the indicated levels, and do not reflect collateral posted. (b) Represents ratings by Moody’s/S&P. If The Bank of New York Mellon’s debt rating had fallen below investment grade on Dec. 31, 2021 and Dec. 31, 2020, existing collateral arrangements would have required us to post additional collateral of $71 million and $41 million, respectively. Offsetting assets and liabilities The following tables present derivative and financial instruments and their related offsets. There were no derivative instruments or financial instruments subject to a legally enforceable netting agreement for which we are not currently netting.

Segment Reporting [Abstract]
Business segments	Business segments We have an internal information system that produces performance data along product and service lines for our three principal business segments and the Other segment. In the fourth quarter of 2021, we disaggregated our former Investment Services business segment into two new business segments, Securities Services and Market and Wealth Services. The Securities Services business segment includes the Asset Servicing and Issuer Services lines of business. The Market and Wealth Services business segment includes the Pershing, Treasury Services and Clearance and Collateral Management lines of business. Our Investment and Wealth Management business segment and the Other segment were not impacted by the resegmentation. Prior periods were revised. The primary products and services and types of revenue for our principal businesses and a description of the Other segment are presented below. Securities Services segment Line of business Primary products and services Primary types of revenue Asset Servicing Custody, Trust & Depositary, accounting, ETF services, middle-office solutions, transfer agency, services for private equity and real estate funds, foreign exchange, securities lending, liquidity/lending services, prime brokerage and data analytics – Investment services fees (includes securities lending revenue) – Net interest revenue – Foreign exchange revenue – Financing-related fees Issuer Services Corporate Trust (trustee, paying agency, fiduciary, escrow and other financial services) and Depositary Receipts (issuer services and support for brokers and investors) – Investment services fees Market and Wealth Services segment Line of business Primary products and services Primary types of revenue Pershing Clearing and custody, investment, wealth and retirement solutions, technology and enterprise data management, trading services and prime brokerage – Investment services fees Treasury Services Integrated cash management solutions including payments, foreign exchange, liquidity management, receivables processing and payables management and trade finance and processing – Investment services fees Clearance and Collateral Management Clearance (including U.S. government and global clearing services) and Global Collateral Management (including tri-party services) – Investment services fees Investment and Wealth Management segment Line of business Primary products and services Primary types of revenue Investment Management Diversified investment management strategies and distribution of investment products – Investment management fees Wealth Management Investment management, custody, wealth and estate planning, private banking services, investment services and information management – Investment management fees Other segment Description Primary types of revenue Includes leasing portfolio, corporate treasury activities including our securities portfolio, derivatives and other trading activity, corporate and bank-owned life insurance, renewable energy and other corporate investments and certain business exits – Investment and other revenue – Other trading revenue – Net gain (loss) on securities – Net interest revenue (expense) Business accounting principles Our business data has been determined on an internal management basis of accounting, rather than GAAP which is used for consolidated financial reporting. These measurement principles are designed so that reported results of the businesses will track their economic performance. Business segment results are subject to reclassification when organizational changes are made, or for refinements in revenue and expense allocation methodologies. Refinements are typically reflected on a prospective basis. The accounting policies of the businesses are the same as those described in Note 1. The results of our segments are presented and analyzed on an internal management reporting basis. • Revenue amounts reflect fee and other revenue generated by each business and include revenue for services provided between the segments that are also provided to third parties. Fee and other revenue transferred between businesses under revenue transfer agreements is included within other fees in each segment. • 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 included in the Securities Services segment. • 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. • The provision for credit losses associated with the respective credit portfolios is reflected in each segment. • Incentives expense related to restricted stock and RSUs is allocated to the segments. • Support and other indirect expenses, including services provided between segments that are not provided to third parties or not subject to a revenue transfer agreement, are allocated to businesses based on internally developed methodologies and reflected in noninterest expense. • 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 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 generally included in the Other segment. • Client deposits serve as the primary funding source for our securities portfolio. We typically allocate all interest revenue to the businesses generating the deposits. Accordingly, accretion related to the portion of the securities portfolio restructured in 2009 has been included in the results of the businesses. • Balance sheet assets and liabilities and their related income or expense are specifically assigned to each business. Segments with a net liability position have been allocated assets. • Goodwill and intangible assets are reflected within individual businesses. The following consolidating schedules present the contribution of our segments to our overall profitability.

International operations	International operationsInternational activity includes investment services fee revenue and investment management and performance fee revenue generating businesses, foreign exchange trading activity, loans and other revenue producing assets and transactions in which the customer is domiciled outside of the U.S. and/or the international activity is resident at an international entity. Due to the nature of our international and domestic activities, it is not possible to precisely distinguish our international operations between internationally and domestically domiciled customers. As a result, it is necessary to make certain subjective assumptions such as: • Income from international operations is determined after internal allocations for interest revenue, taxes, expenses and provision for credit losses. • Expense charges to international operations include those directly incurred in connection with such activities, as well as an allocable share of general support and overhead charges. Total assets, total revenue, income before income taxes and net income of our international operations are shown in the table below.

Summary of significant accounting and reporting policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Nature of operations	Nature of operationsBNY Mellon is a global leader in providing a broad range of financial products and services in domestic and international markets. Through our three principal business segments, Securities Services, Market and Wealth Services and Investment and Wealth Management, we serve institutions, corporations and high-net-worth individuals.
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.
Reclassifications	Certain immaterial reclassifications have been made to prior periods to place them on a basis comparable with current period presentation. In order to combine items of a similar nature within total revenue and to simplify our income statement presentation, in 2021, we made the following reporting changes. The reclassifications had no impact on consolidated total revenue or total revenue for the business segments. Prior periods were reclassified to be comparable with the current period presentation. • Other trading revenue was reclassified from foreign exchange and other trading revenue to investment and other revenue. • Foreign exchange and other trading revenue was renamed foreign exchange revenue. • The impact of foreign currency remeasurement was reclassified from investment and other revenue to foreign exchange revenue. • Income (loss) from consolidated investment management funds was reclassified to investment and other revenue. • Investment and other revenue was reclassified from fee revenue and is reported separately and net securities gains (losses) was combined with investment and other revenue. In addition, the assets and liabilities of consolidated investment management funds were reclassified to other assets and other liabilities, respectively, on the consolidated balance sheet.
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. Our most significant estimates pertain to our allowance for credit losses, goodwill and other intangibles and litigation and regulatory contingencies. 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
Foreign currency translation	Foreign currency translationAssets and liabilities denominated in foreign currencies are translated to U.S. dollars at the rate of exchange on the balance sheet date. Transaction gains and losses are included in the income statement. Translation gains and losses on investments in foreign entities with functional currencies that are not the U.S. dollar are recorded as foreign currency translation adjustments in other comprehensive income (“OCI”). Revenue and expense transactions are translated at the applicable daily rate or the weighted average monthly exchange rate when applying the daily rate is not practical.
Acquired businesses	Acquired businesses The income statement and balance sheet include results of acquired businesses accounted for under the acquisition method of accounting pursuant to Accounting Standards Codification (“ASC”) 805, Business Combinations, and equity investments from the dates of acquisition. Contingent purchase consideration is measured at its fair value and recorded on the purchase date. Any subsequent changes in the fair value of a contingent consideration liability are recorded through the income statement.
Consolidation	Consolidation We evaluate an entity for possible consolidation in accordance with ASC 810, Consolidation . We first determine whether or not we have variable interests in the entity, which are investments or other interests that absorb portions of an entity’s expected losses or receive portions of the entity’s expected returns. Our variable interests may include decision-maker or service provider fees, direct and indirect investments and investments made by related parties, including related parties under common control. If it is determined that we do not have a variable interest in the entity, no further analysis is required and the entity is not consolidated. If we hold a variable interest in the entity, further analysis is performed to determine if the entity is a variable interest entity (“VIE”) or a voting model entity (“VME”). We consider the underlying facts and circumstances of individual entities when assessing whether or not an entity is a VIE. An entity is determined to be a VIE if the equity investors: • do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support; or • lack one or more of the following characteristics of a controlling financial interest: • the power, through voting rights or similar rights, to direct the activities of an entity that most significantly impact the entity’s economic performance; • the obligation to absorb the expected losses of the entity; and • the right to receive the expected residual returns of the entity. We reconsider and reassess whether or not we are the primary beneficiary of a VIE when governing documents or contractual arrangements are changed that would reallocate the obligation to absorb expected losses or receive expected residual returns between BNY Mellon and the other investors. This could occur when BNY Mellon disposes of any portion of its variable interests in the VIE, when we acquire additional variable interests in the VIE, when additional variable interests are issued to other investors or when other investors liquidate their variable interest in the VIE. We consolidate a VIE if it is determined that we have a controlling financial interest in the entity. We have a controlling financial interest in a VIE when we have both (1) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (2) the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to that VIE. For entities that do not meet the definition of a VIE, the entity is considered a VME. We consolidate these entities if we can exert control over the financial and operating policies of an investee, which can occur if we have a 50% or more voting interest in the entity.
Equity method investments, including renewable energy investments	Equity method investments, including renewable energy investments Equity investments of less than a majority but at least 20% ownership are accounted for by the equity method and included in other assets. Earnings on these investments are reflected as investment services fees, investment management and performance fees or investment and other revenue, as appropriate, in the period earned. A loss in value of an equity investment that is determined to be other-than-temporary is recognized by reducing the carrying value of the equity investment to its fair value. Renewable energy investment projects through limited liability companies are accounted for using the equity method of accounting. The hypothetical liquidation at book value (“HLBV”) methodology is used to determine the pre-tax loss that is recognized in each period. HLBV estimates the liquidation value at the beginning and end of each period, with the difference recognized as the amount of loss under the equity method.
Restricted cash and securities	Restricted cash and securities Cash and securities may be segregated under federal and other regulatory requirements and consists of excess client funds held by our broker-dealer entities. Restricted cash is included in interest-bearing deposits with banks on the balance sheet and with cash and due from banks when reconciling the
Securities purchased under resale agreements and securities sold under repurchase agreement	Securities purchased under resale agreements and securities sold under repurchase agreements Securities purchased under resale agreements and securities sold under repurchase agreements are accounted for as collateralized financings. Generally, these agreements are recorded at the amounts at which the securities will be subsequently resold or repurchased, plus accrued interest. Securities purchased under resale agreements are fully collateralized with high-quality liquid securities. Collateral requirements are monitored and additional collateral is received or provided, as required. As such, these transactions carry minimal credit risk and are generally not allocated an allowance for credit losses. Where an enforceable netting agreement exists, resale and repurchase agreements executed with the same counterparty and the same maturity date are reported on a net basis on the balance sheet.
Securities - Debt & Equity	Securities – Debt Debt securities are classified as available-for-sale, held-to-maturity or trading securities when they are purchased. Debt securities are classified as available-for-sale securities when we intend to hold the securities for an indefinite period of time or when the securities may be used for tactical asset/liability purposes and may be sold from time to time to effectively manage interest rate exposure, prepayment risk and liquidity needs. Debt securities are classified as held-to-maturity securities when we intend and have the ability to hold them until maturity. Debt securities are classified as trading securities when our intention is to resell the securities. Available-for-sale securities are measured at fair value. The difference between fair value and amortized cost representing unrealized gains or losses on assets classified as available-for-sale is recorded net of tax as an addition to, or deduction from, OCI, unless an expected credit loss is recognized. Realized gains and losses on sales of available-for-sale securities are reported in investment and other revenue on the income statement. The cost of debt securities sold is determined on a specific identification method. Held-to-maturity securities are measured at amortized cost, which includes expected credit loss, if any. The accounting policy for estimating credit losses related to available-for-sale and held-to-maturity debt securities changed beginning in the first quarter of 2020 as a result of the adoption of ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments . The Company’s policy for recognition of expected credit losses for securities available-for-sale and securities held-to-maturity is contained within “Allowance for credit losses – Securities – Debt” and “Allowance for credit losses – Other” below. Trading securities are measured at fair value and included in trading assets on the balance sheet. Trading revenue includes both realized and unrealized gains and losses. The liability incurred on short-sale transactions, representing the obligation to deliver securities, is included in trading liabilities at fair value. Income on securities purchased is adjusted for amortization of premium and accretion of discount on a level yield basis, generally over their contractual life. For debt securities that are beneficial interests in securitized financial assets and are not high credit quality, ASC 325, Investments – Other , provides that cash flows be discounted at the current yield used to accrete the beneficial interest. A credit loss is recognized when there is an adverse change in expected cash flows. If we intend to sell the security or it is more likely than not that we will be required to sell the security prior to recovery of its cost basis, the security is written down to fair value and the credit and non-credit components of the unrealized loss are recognized in earnings and subsequently accreted to interest income on an effective yield basis over the life of the security. Subsequent increases in the fair value of the security after the write-down are included in OCI. Securities – Equity Investments in equity securities that do not result in consolidation and are not accounted for under the equity method are measured at fair value with changes in the fair value recognized through earnings,
Loans	Loans Loans are reported at amortized cost, net of any unearned income and deferred fees and costs. Certain loan origination and upfront commitment fees, as well as certain direct loan origination and commitment costs, are deferred and amortized as a yield adjustment over the lives of the related loans. Loans held for sale are carried at the lower of cost or fair value.
Troubled debt restructuring/loan modifications	Troubled debt restructurings/loan modifications A modified loan is considered a troubled debt restructuring (“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. Credit losses related to TDRs are accounted for under an individual evaluation methodology (see “Allowance for credit losses” below). Credit losses for anticipated TDRs are generally accounted for similarly to TDRs and are identified when there is a reasonable expectation that a TDR will be executed with the borrower and when we expect the modification to affect the timing or amount of payments and/or the payment term. Due to the coronavirus pandemic, there have been two forms of relief provided for classifying loans as TDRs: The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) and the Interagency Guidance (as defined below). Financial institutions may account for eligible loan modifications either under the CARES Act or the Interagency Guidance. The Company has elected to apply both the CARES Act and the Interagency Guidance, as applicable, in providing borrowers with loan modification relief in response to the coronavirus pandemic. The CARES Act, which became law on March 27, 2020, provides that financial institutions may, subject to certain conditions, elect to temporarily suspend the U.S. GAAP requirements with respect to loan modifications related to the coronavirus pandemic that were current as of Dec. 31, 2019 and that would otherwise be identified and treated as TDRs. On Dec. 27, 2020, the Consolidated Appropriations Act, 2021 was signed into law and extends the period established by the CARES Act under which consideration of TDR identification and accounting triggered by effects of the coronavirus pandemic are suspended. That extension period ended on Jan. 1, 2022. Various banking regulators issued guidance in the April 7, 2020 “Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (revised)” (“Interagency Guidance”) on loan modification treatment pursuant to which financial institutions can apply the U.S. GAAP requirements for loan modifications. In accordance with this guidance, a loan modification is not considered a TDR if the modification is related to the coronavirus pandemic, the borrower had been current when the modification program was implemented, and the modification includes payment deferrals for not more than six months.
Nonperforming assets	Nonperforming assets Commercial loans are placed on nonaccrual status when principal or interest is past due 90 days or more, or when there is reasonable doubt that interest or principal will be collected. When a first or second lien residential mortgage loan reaches 90 days delinquent, it is subject to an individual evaluation of credit loss and placed on nonaccrual status.
Allowance for credit losses	Allowance for credit losses The accounting policy for estimating credit losses related to financial assets measured at amortized cost, including loans and lending-related commitments, changed beginning in the first quarter of 2020 as a result of the adoption of ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments . This ASU also included targeted amendments with respect to credit losses for available-for-sale debt securities. The accounting policy for determining the allowances has been identified as a “critical accounting estimate” as it requires us to make numerous complex and subjective estimates and assumptions relating to amounts which are judgmental and inherently uncertain. Credit quality is monitored by management and is reflected within the allowance for credit losses. The allowance represents management’s estimate of expected credit losses over the expected contractual life of the financial instruments as of the balance sheet date. The allowance methodology is designed to provide procedural discipline in assessing the appropriateness of the allowance. A quantitative methodology and qualitative framework is used to estimate the allowance for credit losses. The qualitative framework is described in further detail within “Allowance for credit losses – Other” below. The quantitative component of our estimate uses models and methodologies that categorize financial assets based on product type, collateral type, and other credit trends and risk characteristics, including relevant information about past events, current conditions and reasonable and supportable forecasts of future economic conditions that affect the collectability of the recorded amounts. The allowance may be determined using various methods, including discounted cash flow methods, loss-rate methods, probability of default methods or other methods that we determine to be appropriate. We estimate our expected credit losses using the probability of default method for the majority of our financial assets. We measure expected credit losses of financial assets on a collective (pool) basis when similar risk characteristics exist. For a financial asset that does not share risk characteristics with other assets, expected credit losses are measured based on an individual evaluation method. In our estimate, with the exception of our small home equity line of credit portfolio, available-for-sale debt securities, and individually evaluated financial assets, we utilize a multi-scenario macroeconomic forecast which includes a weighting of three scenarios: a baseline and upside and downside scenarios and allows us to develop our estimate using a wide span of economic variables. Our baseline scenario reflects a view on likely performance of each global region and the other two scenarios are designed relative to the baseline scenario. This approach incorporates a reasonable and supportable forecast period spanning the life of the asset, and this period includes both an initial estimated economic outlook component as well as a reversion component for each economic input variable. The length of each of the two components depends on the underlying financial instrument, scenario and underlying economic input variable. In general, the initial economic outlook period for each economic input variable under each scenario ranges between several months and two years. The speed at which the scenario-specific forecasts revert to long-term historical mean is based on observed historical patterns of mean reversion at the economic variable input level that are reflected in our model parameter estimates. Certain macroeconomic variables such as unemployment or home prices take longer to revert after a contraction, though specific recovery times are scenario-specific. Reversion will usually take longer the further away the scenario-specific forecast is from the historical mean. On a quarterly basis, within a developed governance structure, we update these scenarios for current economic conditions and may adjust the scenario weighting based on our economic outlook. Allowance for credit losses – Loans and lending-related commitments The allowance for credit losses on loans is presented as a valuation allowance to loans, and the allowance for credit losses on lending-related commitments is recorded in other liabilities. The components of the allowance for credit losses on loans and lending-related commitments consist of the following three elements: • a pooled allowance component for higher risk-rated and pass-rated commercial and institutional credits and loans secured by commercial real estate; • a pooled allowance component for residential mortgage loans; and • an asset-specific allowance component involving individually evaluated credits of $1 million or greater. The first element, a pooled allowance component for higher risk-rated and pass-rated commercial and institutional credits and loans secured by commercial real estate, is based on our expected credit loss model using the probability of default method, which has been adjusted for the forecast of economic conditions. Individual credit analyses are performed on such loans before being assigned a credit rating. Segmentation is established based on risk characteristics of the loans and how risk is monitored. In estimating the terms of the exposures and resulting effect on the measurement of expected credit loss, we consider the impact of potential prepayments as well as the effect of borrower extension options. Borrower ratings are reviewed at least annually and are mapped to third-party databases, including rating agency and default and recovery databases, to support ongoing consistency and validity. Higher risk-rated loans and lending-related commitments are reviewed quarterly. For the higher-risk rated and pass-rated commercial and institutional credits, the loss expected in each loan incorporates the borrower’s credit rating, facility rating and maturity. The loss given default, derived from the facility rating, incorporates a recovery expectation, and for unfunded lending exposures, an estimate of the use of the facility at default (usage given default). The borrower’s probability of default is derived from the associated credit rating. The probability of default and the loss given default are applied to the estimated facility amount at default to determine the quantitative component of the allowance. For each of the different parameters, specific credit models are developed for each segment of our portfolio, including commercial loans and lease financing, financial institutions and other. We use both internal and external data in the development of these parameters. For loans secured by commercial real estate, a separate modeled approach is used that considers collateral specific data and loan maturity, as well as commercial real estate market factors by geographical region and property type under different macroeconomic scenarios. A statistical method is used to simulate the property value and income of each property, and to estimate the probability of default, loss given default and expected credit loss for each loan. The model outputs are established by using a baseline, upside and downside macroeconomic scenario to generate projected property values and incomes. The second element, a pooled allowance component for residential mortgage loans, is determined by first segregating our mortgage pools into two categories: (i) our wealth management mortgages and (ii) our legacy mortgage portfolio disclosed as other residential mortgages. We then apply models to each portfolio to predict prepayments, default rates and loss severity. We consider historical loss experience and use a loan-level, multi-period default model which further segments each portfolio by product type, including first lien fixed rate mortgages, first lien adjustable rate mortgages, second lien mortgages and interest-only mortgages. We calculate the mortgage loss up to loan contractual maturity and embed a reasonable and supportable forecast and macroeconomic variable inputs which are described above. 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 limited internal data. Our legacy mortgage portfolio and home equity line of credit portfolios represent small sub-segments of our mortgage loans. The third element, individually evaluated credits, is based on individual analysis of loans of $1 million and greater which no longer share the risk characteristics with other loans. Factors we consider in measuring the extent of expected credit loss include the payment status, collateral value, the borrower’s financial condition, guarantor support, the probability of collecting scheduled principal and interest payments when due, anticipated modifications of payment structure or term for troubled borrowers, and recoveries if they can be reasonably estimated. We measure the expected credit loss as the difference between the amortized cost basis in the loan and the present value of the expected future cash flows from the borrower which is generally discounted at the loan’s effective interest rate, or the fair value of the collateral, if the loan is collateral dependent. We generally consider nonperforming loans as well as loans that have been or are anticipated to be modified and classified under a troubled debt restructuring for individual evaluation given the risk characteristics of such loans. Allowance for credit losses – Securities – Debt When estimating expected credit losses, we segment our available-for-sale and held-to-maturity debt securities portfolios by major asset class. This is influenced by whether the security is structured or non-structured (i.e., direct obligation), as well as the issuer type. For available-for-sale debt securities with an unrealized loss at the balance sheet date, if we determine that a credit loss exists, the amount is recognized as an allowance for credit losses in securities – available-for-sale, with a corresponding adjustment to the provision for credit losses. We evaluate credit losses at the individual security level and do not recognize credit losses if the fair value exceeds amortized cost, and if we determine that a credit loss exists, we limit the recognition of the loss to the difference between fair value and amortized cost. In our determination of whether an expected credit loss exists, we routinely conduct periodic reviews and examine various quantitative and qualitative factors that are unique to each portfolio, including the severity of the unrealized loss position, agency rating, credit enhancement, cash flow deterioration and other factors. The measurement of an expected credit loss is then based on the best estimate of the present value of cash flows to be collected from the debt security. Generally, cash flows are discounted at the effective interest rate implicit in the debt security. Changes to the present value of cash flows due to the passage of time are recognized within the allowance for credit losses. We estimate expected credit losses for held-to-maturity debt securities using a similar methodology as described in the first allowance element within “Allowance for credit losses – Loans and lending-related commitments” above. The allowance for credit losses on held-to-maturity debt securities is recorded in securities – held-to-maturity. The components of the credit loss calculation for each major portfolio or asset class include a probability of default and loss given default and their values depend on the forecast behavior of variables in the macroeconomic environment. For structured debt securities, we estimated expected credit losses at the individual security level and use a cash flow model to project principal losses. Generally, cash flows are discounted at the effective interest rate implicit in the debt security. The difference is reflected in the allowance for credit losses, and changes to the present value of cash flows due to the passage of time are recognized within the allowance for credit losses. We currently do not require an estimate of expected credit losses to be measured and recorded for U.S. Treasury securities, agency debt securities, and other debt securities that meet certain conditions that are based on a combination of factors such as guarantees, credit ratings and other credit quality factors. These assets are monitored within our established governance structure on a recurring basis to determine if any changes are warranted. Allowance for credit losses – Other financial instruments We also estimate expected credit losses associated with margin loans, reverse repurchase agreements, security lending indemnifications, and deposits with third-party financial institutions using a similar risk rating-based modeling approach as described in the first allowance element within “Allowance for credit losses – Loans and lending-related commitments” above. The allowance for credit losses on reverse repurchase agreements is recorded in federal funds sold and securities purchased under resale agreements; the allowance for credit losses on securities lending indemnifications is recorded in other liabilities and the allowance for credit losses on deposits with third-party financial institutions is recorded in cash and due from banks or interest-bearing deposits with banks. Our reverse repurchase agreements are short term and subject to continuous over-collateralization by our counterparties and timely collateral replenishment, when necessary. As a result, we estimate the expected credit loss related to the uncollateralized portion of the asset at the balance sheet date, if any, and when there is a reasonable expectation that the counterparty will not replenish the collateral in compliance with the terms of the repurchase agreement. This method is also applied to margin lending arrangements and securities lending indemnifications. Allowance for credit losses – Other We do not apply our credit loss measurement methodologies to accrued interest receivable balances related to our loan, debt securities and deposits with third-party financial institution assets given our nonaccrual policy that requires charge-off of interest receivable when deemed uncollectible. Accrued interest receivable related to these instruments, along with other interest-bearing instruments, is included on the consolidated balance sheet. Accrued interest receivable related to each major loan class is disclosed within our credit quality disclosure in Note 5. Our policy for credit losses related to purchased financial assets requires an evaluation to be performed prior to the effective purchase date to determine if more than an insignificant decline in credit quality has occurred during the period between the origination and purchase date, or, in the case of debt securities, the period between the issuance and purchase date. If we purchase a financial asset with more than insignificant deterioration in credit quality, the measurement of expected credit loss is performed using the methodologies described above, and the credit loss is recorded as an allowance for credit losses on the purchase date. Subsequent to purchase, changes (favorable and unfavorable) in expected cash flows are recognized immediately in net income by adjusting the allowance. We evaluate various factors in the determination of whether a more than an insignificant decline in credit quality has occurred and these factors vary depending upon the type of asset purchased. Such factors include changes in risk rating and/or agency rating, collateral deterioration, payment status, purchase price, credit spreads and other factors. We did not purchase any such assets in 2021 or 2020 and did not own such assets as of Dec. 31, 2021 or Dec. 31, 2020. We apply a separate credit loss methodology to accounts receivables to estimate the expected credit losses associated with these short-term receivables which historically have not resulted in significant credit losses. The allowance for credit losses on accounts receivables is reflected in other assets.
Premises and equipment	Premises and equipmentPremises and equipment are carried at cost less accumulated depreciation and amortization. Depreciation and amortization is computed using the straight-line method over the estimated useful life of the owned asset and, for leasehold improvements, over the lesser of the remaining term of the leased facility or the estimated economic life of the improvement. For owned and capitalized assets, estimated useful lives range from two
Leasing	Leasing We determine if an arrangement is a lease at inception. Right-of-use (“ROU”) assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments. The ROU assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date or at lease modification date for certain lease modifications. For all leases, we use a discount rate that represents a collateralized borrowing rate based on similar terms and information available at lease commencement date or at the modification date for certain lease modifications in determining the present value of lease payments. In addition to the lease payments, the determination of an ROU asset may also include certain adjustments related to lease incentives and initial direct costs incurred. Options to extend or terminate a lease are included in the determination of the ROU asset and lease liability only when it is reasonably certain that we will exercise that option. Lease expense for operating leases is recognized on a straight-line basis over the lease term, while the lease expense for finance leases is recognized using the effective interest method. ROU assets are reviewed for impairment when events or circumstances indicate that the carrying amount may not be recoverable. For operating leases, if deemed impaired, the ROU asset is written down and the remaining balance is subsequently amortized on a straight-line basis which results in lease expense recognition that is similar to finance leases. For all leases, we have elected to account for the contractual lease and non-lease components as a single lease component and include them in the calculation of the lease liability. The non-lease variable components, such as maintenance expense and other variable costs, including non-index or rate escalations, have been excluded from the calculation and disclosed separately. Additionally, for certain equipment leases, we apply a portfolio approach to account for the operating lease ROU assets and liabilities. For subleasing activities, the rental income is reported as part of net occupancy expense, as this activity is not a significant business activity and is part of the Company’s customary business practice. For direct finance leases, unearned revenue is accreted over the lives of the leases in decreasing amounts to provide a constant rate of return on the net investment in the leases. We have leveraged lease transactions that were entered into prior to Dec. 31, 2018. These leases are grandfathered under ASC 842, Leases , which became effective Jan. 1, 2019, and will continue to be accounted for under the prior guidance unless the leases are subsequently modified. Revenue on leveraged leases is recognized on a basis to achieve a constant yield on the outstanding investment in the lease, net of the related deferred tax liability, in the years in which the net investment is positive. Gains and losses on residual values of leased equipment sold are included in investment and
Software	Software We capitalize costs relating to acquired software and internal-use software development projects that provide new or significantly improved functionality. We capitalize projects that are expected to result in longer-term operational benefits, such as replacement systems or new applications that result in significantly increased operational efficiencies or functionality. All other costs incurred in connection with an internal-use software project are expensed as incurred. Capitalized software is recorded in other assets on the balance sheet. We record amortization of capitalized software in software and equipment expense on the income statement.
Identified intangible assets and goodwill	Identified intangible assets and goodwill Identified intangible assets with estimable lives are amortized in a pattern consistent with the assets’ identifiable cash flows or using a straight-line method over their remaining estimated benefit periods if the pattern of cash flows is not estimable. Intangible assets with estimable lives are reviewed for possible impairment when events or changed circumstances may affect the underlying basis of the asset. Goodwill and intangibles with indefinite lives are not amortized, but are assessed annually for impairment, or more often if events and circumstances indicate it is more likely than not they may be impaired and to determine if the lives are no longer indefinite and should be amortized. The amount of goodwill impairment, if any, is determined by the excess of the carrying value of the reporting unit over its fair value. The accounting policy for valuing and impairment testing of identified intangible assets and goodwill has been identified as a “critical accounting estimate” as it requires us to make numerous complex and subjective estimates. See Note 7 for additional disclosures related to goodwill and intangible assets.
Investments in qualified affordable housing projects	Investments in qualified affordable housing projects Investments in qualified affordable housing projects through a limited liability entity are accounted for
Seed capital	Seed capital Seed capital investments are generally classified as other assets and carried at fair value unless we are required to consolidate the investee due to having a controlling financial interest. Unrealized gains and losses on seed capital investments are recorded in investment and other revenue. Certain risk retention investments in our collateralized loan obligations (“CLOs”) are classified as available-for-sale securities.
Noncontrolling interests	Noncontrolling interests Noncontrolling interests represent the portion of consolidated entities that are owned by parties other than BNY Mellon. Noncontrolling interests included in permanent equity are adjusted for the income or loss attributable to the noncontrolling interest holders and any distributions to those shareholders. Redeemable noncontrolling interests are reported as temporary equity and represent the redemption value resulting from equity-classified share-based payment arrangements that are currently redeemable or are expected to become redeemable. We recognize changes in the redemption value of the redeemable noncontrolling interests as they occur and adjust the carrying value to be equal to the redemption value.
Fee revenue	Fee revenue Investment services fee revenue and investment management and performance fee revenue are based on terms specified in a contract with a customer and are shown net of fee waivers and exclude any amounts collected on behalf of third parties. Revenue is recognized when, or as, a performance obligation is satisfied by transferring control of a good or service to a customer. A performance obligation may be satisfied over time or at a point in time. Revenue from a performance obligation satisfied over time is recognized by measuring our progress in satisfying the performance obligation in a manner that reflects the transfer of goods and services to the customer. Revenue from a performance obligation satisfied at a point in time is recognized at the point in time the customer obtains control of the promised good or service. The amount of revenue recognized reflects the consideration we expect to be entitled to in exchange for the promised goods and services. Taxes assessed by a governmental authority, that are both imposed on, and concurrent with, a specific revenue-producing transaction, are collected from a customer and are excluded from revenue. Performance fees are recognized in the period in which the performance fees are earned and become determinable. Performance fees are constrained until all uncertainties are resolved and reversal of previously recorded amounts is not probable. Performance fees are generally calculated as a percentage of the applicable portfolio’s performance in excess of a benchmark index or a peer group’s performance. When a portfolio underperforms its benchmark or fails to generate positive performance, subsequent years’ performance must generally exceed this shortfall prior to fees being earned. Amounts billable, which are subject to a clawback if future performance thresholds in current or future years are not met, are not recognized since the fees are potentially uncollectible. These fees are recognized when it is determined that they will be collected. When a multi-year performance contract provides that fees earned are billed ratably over the performance period, only the portion of the fees earned that are non-refundable are recognized. Additionally, we recognize revenue from non-refundable, implementation fees under outsourcing contracts using a straight-line method, commencing in the period the ongoing services are performed through the expected term of the contractual relationship. Incremental direct set-up costs of implementation, up to the related customer margin or minimum fee revenue amount, are deferred and amortized over the same period that the related implementation fees are recognized. If a client terminates an outsourcing contract prematurely, the unamortized deferred incremental direct set-up costs and the unamortized deferred implementation fees related to that contract are recognized in the period the contract is terminated.
Net interest revenue	Net interest revenue Revenue on interest-earning assets and expense on interest-bearing liabilities are recognized based on the effective yield of the related financial instrument. The amortization of premiums and accretion of discounts are included in interest revenue and are adjusted for prepayments when they occur, such that, the effective yield remains constant throughout the contractual life of the security. Negative interest incurred on assets or charged on liabilities is presented as contra interest revenue and contra interest expense, respectively.
Pension	Pension The measurement date for BNY Mellon’s pension plans is December 31. Plan assets are determined based on fair value generally representing observable market prices. The projected benefit obligation is determined based on the present value of projected benefit distributions at an assumed discount rate. The discount rate utilized is based on the yield curves of high-quality corporate bonds available in the marketplace. The net periodic pension expense or credit includes service costs (if applicable), interest costs based on an assumed discount rate, an expected return on plan assets based on an actuarially derived market-related value, amortization of prior service cost and amortization of prior years’ actuarial gains and losses. Actuarial gains and losses include gains or losses related to changes in the amount of the projected benefit obligation or plan assets resulting from demographic or investment experience different than assumed, changes in the discount rate or other assumptions. To the extent an actuarial gain or loss exceeds 10% of the greater of the projected benefit obligation or the market-related value of plan assets, the excess is generally recognized over the future service periods of active employees. Benefit accruals under the U.S. pension plans and the largest foreign pension plan in the UK are frozen. Future unrecognized actuarial gains and losses for these frozen plans that exceed a threshold amount are amortized over the average future life expectancy of plan participants with a maximum of 15 years. Our expected long-term rate of return on plan assets is based on anticipated returns for each applicable asset class. Anticipated returns are weighted for the expected allocation for each asset class and are based on forecasts for prospective returns in the equity and fixed-income markets, which should track the long-term historical returns for these markets. We also consider the growth outlook for U.S. and global economies, as well as current and prospective interest rates. The market-related value utilized to determine the expected return on plan assets is based on the fair value of plan assets adjusted for the difference between expected returns and actual performance of plan assets. The difference between actual experience and expected returns on plan assets is included as an adjustment in the market-related value over a five
Stock-based compensation	Stock-based compensation Compensation expense relating to share-based payments is recognized in staff expense on the income statement, on a straight-line basis, over the applicable vesting period. Certain stock compensation grants vest when the employee retires. New grants with this feature are expensed by the first date the employee is eligible to retire. We estimate forfeitures when recording compensation cost related to share-based payment awards.
Severance	Severance BNY Mellon provides separation benefits for U.S.-based employees through The Bank of New York Mellon Corporation Supplemental Unemployment Benefit Plan. These benefits are provided to eligible employees separated from their jobs for business reasons not related to individual performance. Basic separation benefits are generally based on the employee’s years of continuous benefited service. Severance for employees based outside of the U.S. is determined in accordance with local agreements and legal requirements. Severance expense is recorded
Income taxes	Income taxesWe record current tax liabilities or assets through charges or credits to the current tax provision for the estimated taxes payable or refundable for the current year. Deferred tax assets and liabilities are recorded for future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. A deferred tax valuation allowance is established if it is more likely than not that all or a portion of the deferred tax assets will not be realized. A tax position that fails to meet a more-likely-than-not recognition threshold will result in either reduction of current or deferred tax assets, and/or recording of current or deferred tax liabilities. Interest and penalties related to income taxes are recorded as income tax expense.
Derivative financial instruments	Derivative financial instruments Derivatives are recorded on the balance sheet at fair value and include futures, forwards, interest rate swaps, foreign currency swaps and options and similar products. Derivatives in an unrealized gain position are recognized as assets while derivatives in unrealized loss position are recognized as liabilities. Derivatives are reported net by counterparty and after consideration of cash collateral, to the extent subject to legally enforceable netting agreements. Derivatives designated and effective in qualifying hedging relationships are classified in other assets or other liabilities on the balance sheet. All other derivatives are classified within trading assets or trading liabilities on the balance sheet. Gains and losses on trading derivatives are generally included in foreign exchange revenue or investment and other revenue, as applicable. We enter into various derivative financial instruments for non-trading purposes primarily as part of our asset/liability management process. These non-trading derivatives are designated as one of three types of hedge activities: fair value, cash flow or net investment hedges. Gains and losses on derivatives associated with fair value hedges are recorded in income as well as any change in the value of the related hedged item associated with the designated risks being hedged. Gains and losses on cash flow hedges are recorded in OCI, until reclassified into earnings in the same period the hedged item impacts earnings. Foreign currency transaction gains and losses related to a hedged net investment in a foreign operation, net of their tax effect, are recorded with cumulative foreign currency translation adjustments within OCI. To qualify for hedge accounting, each hedge relationship is required to be highly effective at reducing the risk associated with the exposure being hedged, both prospectively and retrospectively. We formally document all relationships, including hedging instruments and hedged items, as well as our risk management objectives and strategy for undertaking each hedging transaction. At inception, the potential cause of ineffectiveness related to each of our hedges is assessed to determine if we can expect the hedge to be highly effective over the life of the transaction. At hedge inception, we document the methodology to be utilized for evaluating effectiveness on an ongoing basis, and we monitor ongoing hedge effectiveness at least quarterly. For qualifying fair value hedges, changes in the fair value of the derivative, and changes in the value of the hedged item associated with the designated risks being hedged, are recognized in earnings. Certain amounts excluded from the assessment of effectiveness are recorded in OCI and recognized in earnings through an amortization approach over the life of the derivative. We discontinue hedge accounting prospectively when we determine that the hedge is no longer effective or the derivative expires, is sold, or management discontinues the derivative’s hedge designation. Subsequent gains and losses on these derivatives are included in foreign exchange revenue or other trading revenue, as applicable. For discontinued fair value hedges, the accumulated gain or loss on the hedged item is amortized on a yield basis over the remaining life of the hedged item. For qualifying cash flow hedges, changes in the fair value of the derivative are recorded in OCI, until reclassified into earnings in the same period the hedged item impacts earnings. If the hedge relationship is terminated, then the change in value will be reclassified from OCI to earnings when the cash flows that were previously hedged affect earnings. If cash flow hedge accounting is discontinued as a result of a forecasted transaction no longer being probable to occur, then the amount reported in OCI is immediately reclassified to current earnings. Derivative amounts affecting earnings are recognized in the same income statement line as the hedged item affects earnings, principally interest revenue, interest expense, foreign exchange revenue and staff expense. Foreign currency transaction gains and losses related to qualifying hedges of net investments in a foreign operation are recorded with cumulative foreign currency translation adjustments within OCI net of their tax effect. The Company evaluates effectiveness of its foreign currency derivatives designated as hedges of its net investments utilizing the forward rate method.
Earnings per common share	Earnings per common share Earnings per common share is calculated using the two-class method under which earnings are allocated to common shareholders and holders of participating securities. Unvested stock-based compensation awards that contain non-forfeitable rights to dividends or dividend equivalents are considered participating securities under the two-class method. Basic earnings per share is calculated by dividing net income allocated to common shareholders of BNY Mellon by the average number of common shares outstanding and vested stock-based compensation awards where recipients have satisfied either the explicit vesting terms or retirement-eligibility requirements. Diluted earnings per common share is computed under the more dilutive of either the treasury stock method or the two-class method. We increase the average number of shares of common stock outstanding by the assumed number of shares of common stock that would be issued assuming the exercise of stock options and the issuance of shares related to stock-based compensation awards using the treasury stock method, if dilutive. Diluted earnings per share is calculated by dividing net income allocated to common shareholders of BNY Mellon by the adjusted average number of common shares outstanding.
Statement of cash flows	Statement of cash flowsWe have defined cash as cash and due from banks. Cash flows from hedging activities are classified in the same category as the items hedged. Distributions received from equity method investees are classified as cash inflows from operating activities on the statement of cash flows. Excess returns on investments of equity method investments are classified as cash flows from investing activities on the statement of cash flows.
Fair value measurement	Fair value measurementFair value is defined 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. A three-level hierarchy for fair value measurements is utilized based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. BNY Mellon’s own creditworthiness is considered when valuing liabilities. Fair value 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 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 record financial instruments at fair value. Most derivative contracts are valued using models which are calibrated to observable market data and employ standard market pricing theory for their valuations. Valuation models incorporate counterparty credit risk 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’s own credit spreads, as implied by the credit default swap market. 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 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 A three-level valuation hierarchy is used 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 certain debt and equity securities, derivative financial instruments actively traded on exchanges and highly liquid government bonds. 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 financial instruments whose model inputs are observable in the market or can be corroborated by market-observable data. Examples in this category are MBS, corporate debt securities and OTC derivative contracts. Level 3 : Inputs to the valuation methodology are unobservable and significant to the fair value measurement. 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. Valuation methodology 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 We determine fair value primarily based on pricing sources with reasonable levels of price transparency. 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 U.S. Treasury and certain sovereign debt securities that are actively traded in highly liquid OTC markets, money market funds and exchange-traded equities. If quoted market prices are not available, fair values are primarily determined using pricing models using observable trade data, market data, 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 MBS, state and political subdivisions, certain sovereign debt, corporate bonds and foreign covered bonds. 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. At Dec. 31, 2021, approximately 99% of our securities were valued by pricing sources with reasonable levels of price transparency. The remaining securities were generally valued using observable inputs. Additional disclosures of securities are provided in Note 4. 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. As of Dec. 31, 2021, we have no instruments included in Level 3 of the valuation hierarchy. Derivative financial instruments We classify exchange-traded derivative financial instruments valued using quoted prices in Level 1 of the valuation hierarchy. Examples include exchange-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 models that use as their basis readily observable market parameters, and we classify them in Level 2 of the valuation hierarchy. Such derivative financial instruments include swaps and options, foreign exchange spot and forward contracts 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 may include long-dated swaps and options, where parameters may be unobservable for longer maturities; and certain highly structured products, where correlation risk is unobservable. As of Dec. 31, 2021, we have no Level 3 derivatives. Additional disclosures of derivative instruments are provided in Note 23. Seed capital In our Investment and Wealth Management business segment, we make seed capital investments in certain funds we manage. Seed capital is generally included in other assets on the consolidated balance sheet. When applicable, we value seed capital based on the published NAV of the fund. 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. Interests in securitizations For the interests in securitizations that are classified in trading assets—equity instruments 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. These interests in securitizations matured in 2021. Other assets measured at NAV We hold private equity investments, primarily SBICs, which are compliant with the Volcker Rule. There

Summary of Transactions in the Allowance for Credit Losses	Activity in the allowance for credit losses on loans and lending-related commitments is presented below. This does not include activity in the allowance for credit losses related to other financial instruments, including cash and due from banks, interest-bearing deposits with banks, federal funds sold and securities purchased under resale agreements, held-to-maturity securities, available-for-sale securities and accounts receivable. In 2019, the allowance for loan losses and lending-related commitments was accounted for under ASC 450, Contingencies , to absorb losses inherent in the loan portfolio as of the balance sheet date, also referred to as the incurred loss methodology. Key elements of our incurred loss methodology included a quantitative assessment for higher risk-rated credits, impaired credits and residential mortgage loans, as well as a qualitative assessment based on internal and environmental risk factors. This methodology differed from the estimate of expected credit losses in 2020 and 2021 primarily in that it was based on historical loss experience and did not include an estimate of credit losses using a reasonable and supportable forecast methodology.
