Accounting Policies [Abstract]
Basis of presentation	Basis of presentation In this Quarterly Report on Form 10-Q, references to “our,” “we,” “us,” “BNY Mellon,” the “Company” and similar terms refer to The Bank of New York Mellon Corporation and its consolidated subsidiaries. The term “Parent” refers to The Bank of New York Mellon Corporation but not its subsidiaries. Basis of presentation The accounting and financial reporting policies of BNY Mellon, a global financial services company, conform to U.S. GAAP and prevailing industry practices. For information on our significant accounting and reporting policies, see Note 1 in our 2018 Annual Report. The accompanying consolidated financial statements are unaudited. In the opinion of management, all adjustments necessary for a fair presentation of financial position, results of operations and cash flows for the periods presented have been made. These financial statements should be read in conjunction with our 2018 Annual Report. Certain immaterial reclassifications have been made to prior periods to place them on a basis comparable with the current period presentation. Use of estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates based upon assumptions about future economic and market conditions which affect reported amounts and related disclosures in our financial statements. Although our current estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that actual conditions could be worse than anticipated in those estimates, which could materially affect our results of operations and financial condition. Amounts subject to estimates are items such as allowance for loan losses and lending-related commitments, fair value of financial instruments and derivatives, goodwill and other intangibles and litigation and regulatory contingencies. Among other effects, such changes in estimates could result in future impairments of goodwill and intangible assets and establishment of allowances for loan losses and lending-related commitments as well as accruals for litigation and regulatory contingencies.

Accounting Changes and Error Corrections [Abstract]
Accounting changes and new accounting guidance	Accounting changes and new accounting guidance The following accounting changes and new accounting guidance were adopted in the first quarter of 2019. ASU 2016-02, Leases In February 2016, the FASB issued an ASU, Leases . The primary objective of this ASU is to increase transparency and comparability by recognizing lease assets and liabilities on the balance sheet and expand related disclosures. This ASU requires a “right-of-use” asset and a payment obligation liability on the balance sheet for most leases and subleases. Additionally, depending on the lease classification under the standard, it may result in different expense recognition patterns and classification than under existing accounting principles. For leases classified as finance leases, it will result in higher expense recognition in the earlier periods and lower expense in the later periods of the lease. The Company adopted this guidance on Jan. 1, 2019 using the alternative transition method on a prospective basis and recognized right-of-use assets of $1.3 billion and lease liabilities of $1.5 billion on the consolidated balance sheet, both based on the present value of the expected remaining lease payments. See Note 6 for the disclosures required by this ASU. ASU 2018-02, Income Statement—Reporting Comprehensive Income: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income In February 2018, the FASB issued an ASU, Income Statement—Reporting Comprehensive Income: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU permits a reclassification from accumulated other comprehensive income to retained earnings for the tax effects of items within accumulated other comprehensive income that do not reflect the lower statutory tax rate which was enacted by the 2017 U.S. tax legislation. BNY Mellon adopted this guidance in the first quarter of 2019, which resulted in a $90 million

Business Combinations [Abstract]
Acquisitions and dispositions	Acquisitions and dispositions We sometimes structure our acquisitions with both an initial payment and later contingent payments tied to post-closing revenue or income growth. Contingent payments totaled $4 million in the third quarter of 2019 and $6 million in the first nine months of 2019 . A t Sept. 30, 2019 , we are potentially obligated to pay additional consideration which, using reasonable assumptions, could range from $4 million to $13 million over the next three years , but could be higher as certain of the arrangements do not contain a contractual maximum. The transactions described below did not have a material impact on BNY Mellon’s results of operations. Transactions in 2018 On Jan. 2, 2018, BNY Mellon completed the sale of CenterSquare, one of our Investment Management boutiques, and recorded a gain on this transaction. CenterSquare had approximately $10 billion in AUM in U.S. and global real estate and infrastructure investments. In addition, goodwill of $52 million was removed from the consolidated balance sheet as a result of this sale. On June 29, 2018, BNY Mellon completed the exchange of its majority equity interest in Amherst Capital Management LLC for a minority equity stake in Amherst Holdings LLC. Goodwill of $13 million was removed from the consolidated balance sheet and a gain was recorded as a result of this sale.

Specifically, $70 million of the unrealized losses at Sept. 30, 2019 and $87 million at Dec. 31, 2018 reflected in the available-for-sale sections of the tables below relate to certain securities (primarily Agency RMBS) that were transferred in prior periods 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 sections of 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 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.

Other-than-temporary impairment For each security in the securities portfolio, a quarterly review is conducted to determine if an OTTI has occurred. See Note 1 of the Notes to Consolidated Financial Statements in our 2018 Annual Report for a discussion of the determination of OTTI. The following table reflects securities credit losses recorded in earnings. The beginning balance represents the credit loss component for which OTTI occurred on debt securities in prior periods. The additions represent the first time a debt security was credit impaired or when subsequent credit impairments have occurred. The deductions represent credit losses on securities that have been sold, are required to be sold, or for which it is our intention to sell.

The components of the assets pledged at Sept. 30, 2019 included $98 billion of securities, $13 billion of loans, $4 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, 2018 , BNY Mellon had pledged assets of $120 billion , including $96 billion pledged as collateral for potential borrowing at the Federal Reserve Discount Window and $7 billion pledged as collateral for borrowing at the FHLB. The components of the assets pledged at Dec. 31, 2018 included $100 billion of securities, $15 billion of loans, $4 billion of trading assets and $1 billion of interest-bearing deposits with banks. At Sept. 30, 2019 and Dec. 31, 2018 , pledged assets included $17 billion and $13 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 Sept. 30, 2019 and Dec. 31, 2018 , the market value of the securities received that can be sold or repledged was $129 billion and $151 billion , respectively. We routinely sell or repledge these securities through delivery to third parties. As of Sept. 30, 2019 and Dec. 31, 2018 , the market value of securities collateral sold or repledged was $83 billion and $101 billion , respectively. Restricted cash and securities Cash and securities may be segregated under federal and other regulations or requirements.

We modified loans of $4 million in the third quarter of 2019 , $1 million in the third quarter of 2018 and less than $1 million in the second quarter of 2019 . The loans were primarily other residential mortgages. 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. The following tables present information about credit quality indicators. Commercial loan portfolio Commercial loan portfolio – Credit risk profile by creditworthiness category Commercial Commercial real estate Financial institutions Sept. 30, 2019 Dec. 31, 2018 Sept. 30, 2019 Dec. 31, 2018 Sept. 30, 2019 Dec. 31, 2018 (in millions) Investment grade $ 1,652 $ 2,036 $ 4,753 $ 4,184 $ 11,346 $ 9,586 Non-investment grade 41 96 557 603 2,068 1,997 Total $ 1,693 $ 2,132 $ 5,310 $ 4,787 $ 13,414 $ 11,583 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. Wealth management loans and mortgages Wealth management loans and mortgages – Credit risk profile by internally assigned grade Sept. 30, 2019 Dec. 31, 2018 (in millions) Wealth management loans: Investment grade $ 6,966 $ 6,901 Non-investment grade 57 106 Wealth management mortgages 8,833 8,958 Total $ 15,856 $ 15,965 Wealth management non-mortgage loans are not typically rated by external rating agencies. A majority of the wealth management loans are secured by the customers’ investment management accounts or custody accounts. Eligible assets pledged for these loans are typically investment grade fixed-income securities, equities and/or mutual funds. Internal ratings for this portion of the wealth management portfolio, therefore, would equate to investment-grade external ratings. Wealth management loans are provided to select customers based on the pledge of other types of assets, including business assets, fixed assets or a modest amount of commercial real estate. For the loans collateralized by other assets, the credit quality of the obligor is carefully analyzed, but we do not consider this portfolio of loans to be investment grade. Credit quality indicators for wealth management mortgages are not correlated to external ratings. Wealth management mortgages are typically loans to high-net-worth individuals, which are secured primarily by residential property. These loans are primarily interest-only, adjustable rate mortgages with a weighted-average loan-to-value ratio of 62% at origination. In the wealth management portfolio, less than 1% of the mortgages were past due at Sept. 30, 2019 . At Sept. 30, 2019 , the wealth management mortgage portfolio consisted of the following geographic concentrations: California - 23% ; New York - 18% ; Massachusetts - 10% ; Florida - 8% ; and other - 41% . Other residential mortgages The other residential mortgage portfolio primarily consists of 1-4 family residential mortgage loans and totaled $520 million at Sept. 30, 2019 and $594 million at Dec. 31, 2018 . These loans are not typically correlated to external ratings. Included in this portfolio at Sept. 30, 2019 were $102 million of mortgage loans purchased in 2005, 2006 and the first quarter of 2007, of which, 11% of the serviced loan balance was at least 60 days delinquent. Overdrafts Overdrafts primarily relate to custody and securities clearance clients and totaled $5.3 billion at Sept. 30, 2019 and $5.5 billion at Dec. 31, 2018 . Overdrafts occur on a daily basis primarily in the custody and securities clearance business and are generally repaid within two business days. 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 $10.5 billion of secured margin loans at Sept. 30, 2019 compared with $13.5 billion at Dec. 31, 2018 . Margin loans are collateralized with marketable securities, and borrowers are required to maintain a daily collateral margin in excess of 100% of the value of the loan. We have rarely suffered a loss on these types of loans and do not allocate any of our allowance for credit losses to margin loans. Reverse repurchase agreements Reverse repurchase agreements are transactions fully collateralized with high-quality liquid securities. These transactions carry minimal credit risk and therefore are not allocated an allowance for credit losses.

Leasing

Leases [Abstract]
Leasing	Leasing Significant accounting policy 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. We use our incremental borrowing rate based on the information available at commencement date of the lease 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. We have elected to account for the lease and non-lease components as a single lease component and exclude the non-lease variable components. Additionally, for certain equipment leases, we apply a portfolio approach to account for the operating lease ROU assets and liabilities. BNY Mellon engages in subleasing activities and reports the rental income 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. BNY Mellon engages in leverage lease transactions that were entered into prior to Dec. 31, 2018. These leases are grandfathered under the new standard and will continue to be accounted for under the prior guidance unless subsequently modified. Leases We have operating and finance leases for corporate offices, data centers and certain equipment. Our leases have remaining lease terms of one year to 20 years , some of which include options to extend or terminate the lease. In some of our corporate office locations, we may enter into sublease arrangements for portions or all of the space and/or lease term.

IS - Investment Services segment. IM - Investment Management segment. Contract balances Our clients are billed based on fee schedules that are agreed upon in each customer contract. Receivables from customers were $2.4 billion at Sept. 30, 2019 and $2.5 billion at Dec. 31, 2018 . An allowance is maintained for accounts receivable which is generally based on the number of days outstanding. Adjustments to the allowance are recorded in other expense on the consolidated income statement. We recorded a provision of $2 million in the third quarter of 2019 , third quarter of 2018 and second quarter of 2019 and $8 million in the first nine months of 2019 and first nine months of 2018 . 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 $47 million at Sept. 30, 2019 and $36 million at Dec. 31, 2018 . Accrued revenues recorded as contract assets are usually billed on an annual basis. There were no impairments recorded on contract assets in the first nine months of 2019 . 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 $193 million at Sept. 30, 2019 and $171 million at Dec. 31, 2018 . Contract liabilities are included in other liabilities on the consolidated balance sheet. Revenue recognized in the third quarter of 2019 relating to contract liabilities as of June 30, 2019 was $61 million . Revenue recognized in the first nine months of 2019 relating to contract liabilities as of Dec. 31, 2018 was $91 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 $91 million at Sept. 30, 2019 and $98 million at Dec. 31, 2018 . 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 $7 million in the third quarter of 2019 , $6 million in the third quarter of 2018 , $5 million in the second quarter of 2019 and $17 million in the first nine months of 2019 and first nine months of 2018 . 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 $17 million at Sept. 30, 2019 and $20 million at Dec. 31, 2018 . These capitalized costs are amortized on a straight-line basis over the expected contract period which generally range from seven to nine years. The amortization is included in other expense on the consolidated income statement and totaled $1 million in the third quarter of 2019 and third quarter of 2018 , $2 million in the second quarter of 2019 and $4 million in the first nine months of 2019 and first nine months of 2018 . There were no impairments recorded on capitalized contract costs in the first nine months of 2019 . Unsatisfied performance obligations We do not have any unsatisfied performance obligations other than those that are subject to a practical expedient election under Accounting Standards Codification (“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.

Income Tax Disclosure [Abstract]
Income taxes	Income taxes The provision for income tax was $246 million ( 19.1% effective tax rate) in the third quarter of 2019 , $220 million ( 16.5% effective tax rate) in the third quarter of 2018 and $264 million ( 20.5% effective tax rate) in the second quarter of 2019 . The effective rate for the third quarter of 2018 was impacted by adjustments to the provisional estimates for U.S. tax legislation and other changes. Our total tax reserves as of Sept. 30, 2019 were $147 million compared with $135 million at June 30, 2019 . If these tax reserves were unnecessary, $147 million would affect the effective tax rate in future periods. We recognize accrued interest and penalties, if applicable, related to income taxes in the provision for income taxes on the consolidated income statement. Included in the balance sheet at Sept. 30, 2019 is accrued interest, where applicable, of $27 million . The additional tax expense related to interest for the nine months ended Sept. 30, 2019 was $9 million , compared with $3 million for the nine months ended Sept. 30, 2018 . It is reasonably possible the total reserve for uncertain tax positions could decrease within the next 12 months by approximately $100 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 2013. Our New York State, New York City and UK income tax returns are closed to examination through 2012.

Fair Value Disclosures [Abstract]
Fair value measurement	Fair value measurement Fair 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. See Note 19 of the Notes to Consolidated Financial Statements in our 2018 Annual Report for information on how we determine fair value and the fair value hierarchy. The following tables present the financial instruments carried at fair value at Sept. 30, 2019 and Dec. 31, 2018 , 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.

Fair Value Disclosures [Abstract]
Fair value option	Fair value option We elected fair value as an alternative measurement for selected financial assets and liabilities. 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 Sept. 30, 2019 Dec. 31, 2018 (in millions) Assets of consolidated investment management funds: Trading assets $ 349 $ 243 Other assets 32 220 Total assets of consolidated investment management funds $ 381 $ 463 Liabilities of consolidated investment management funds: Trading liabilities $ 7 $ — Other liabilities 8 2 Total liabilities of consolidated investment management funds $ 15 $ 2 BNY Mellon values 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 value of the assets and liabilities are recorded in the consolidated income statement as investment income of consolidated investment management funds and in the interest of investment management fund note holders, respectively. We have elected the fair value option on $240 million of long-term debt. The fair value of this long-term debt was $386 million at Sept. 30, 2019 and $371 million at Dec. 31, 2018 . The long-term debt is valued using observable market inputs and is included in Level 2 of the valuation hierarchy. The following table presents the changes in fair value of long-term debt recorded in foreign exchange and other trading revenue in the consolidated income statement.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative instruments	Derivative instruments We use derivatives to manage exposure to market risk, including interest rate risk, equity price risk and foreign currency risk, as well as credit risk. Our trading activities are focused on acting as a market- maker for our customers and facilitating customer trades in 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 the third quarter of 2019 . 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 LIBOR. We also utilize interest rate swaps and forward exchange contracts as cash flow hedges to manage our exposure to interest and foreign exchange rate changes. The available-for-sale securities hedged consist of U.S. Treasury bonds, agency and non-agency commercial MBS, sovereign debt, corporate bonds and covered bonds that had original maturities of 30 years or less at initial purchase. At Sept. 30, 2019 , $12.6 billion face amount of available-for-sale securities were hedged with interest rate swaps designated as fair value hedges that had notional values of $12.6 billion . The fixed rate long-term debt instruments hedged generally have original maturities of five to 30 years. In fair value hedging relationships, debt is hedged with “receive fixed rate, pay variable rate” swaps. At Sept. 30, 2019 , $13.9 billion par value of debt was hedged with interest rate swaps designated as fair value hedges that had notional values of $13.9 billion . In addition, at Sept. 30, 2019 , the Company utilized interest rate swaps with notional values of $1.0 billion as cash flow hedges to convert floating rate long-term debt with a par value of $1.0 billion to a fixed interest rate. A pre-tax loss of $1 million was recognized in OCI related to the cash flow hedges at Sept. 30, 2019 and will be reclassified to earnings over the next 12 months . 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 12 months or less as cash flow hedges to hedge our foreign exchange exposure to Indian rupee, British pound, Hong Kong dollar, Singapore dollar and Polish zloty revenue and expense transactions in entities that have the U.S. dollar as their functional currency. As of Sept. 30, 2019 , the hedged forecasted foreign currency transactions and designated forward foreign exchange contract hedges were $369 million (notional), with a pre-tax loss of $1 million recorded in accumulated OCI. This loss 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 Sept. 30, 2019 , $139 million face amount of available-for-sale securities were hedged with foreign currency forward contracts that had a notional value of $139 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. Changes in the value of the forward foreign exchange contracts offset the changes in value of the foreign investments due to changes in foreign exchange rates. The change in fair market value of these forward foreign exchange contracts is reported within foreign currency translation adjustments in shareholders’ equity, net of tax. At Sept. 30, 2019 , forward foreign exchange contracts with notional amounts totaling $7.3 billion were designated as net investment hedges. In addition to forward foreign exchange contracts, we also designate non-derivative financial instruments as hedges of our net investments in foreign subsidiaries. Those non-derivative financial instruments designated as hedges of our net investments in foreign subsidiaries were all long-term liabilities of BNY Mellon in various currencies, and, at Sept. 30, 2019 , had a combined U.S. dollar equivalent value of $167 million .

(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 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 $815 million and $700 million , respectively, at Sept. 30, 2019 , and $809 million and $1,040 million , respectively, at Dec. 31, 2018 . 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 and other trading revenue on the consolidated income statement. The following table presents our foreign exchange and other trading revenue. Foreign exchange and other trading revenue (in millions) 3Q19 2Q19 3Q18 YTD19 YTD18 Foreign exchange $ 129 $ 150 $ 150 $ 439 $ 504 Other trading revenue 21 16 5 47 47 Total foreign exchange and other trading revenue $ 150 $ 166 $ 155 $ 486 $ 551 Foreign exchange revenue includes income from purchasing and selling foreign currencies and currency forwards, futures and options. Other trading revenue reflects results from trading in cash instruments including fixed income and equity securities and 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 a de minimis loss in the third quarter of 2019 and gains of $7 million in the third quarter of 2018 , $5 million in the second quarter of 2019 , $23 million in the first nine months of 2019 and $6 million in the first nine months of 2018 . We manage trading risk through a system of position limits, a 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-day holding period, utilizes a 99% confidence level and incorporates non-linear product characteristics. The VaR model is one of several statistical models used to develop economic capital results, which are allocated to lines of business for computing risk-adjusted performance. 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 in other risk management materials. Counterparty credit risk and collateral We assess credit risk of our counterparties through regular examination of their financial statements, confidential communication with the management of those counterparties and regular monitoring of publicly available credit rating information. This and other information is used to develop proprietary credit rating metrics used to assess credit quality. Collateral requirements are determined after a comprehensive review of the credit quality of each counterparty. Collateral is generally held or pledged in the form of cash and/or highly liquid government securities. Collateral requirements are monitored and adjusted daily. Additional disclosures concerning derivative financial instruments are provided in Note 16. 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. Sept. 30, 2019 Dec. 31, 2018 (in millions) Aggregate fair value of OTC derivatives in net liability positions (a) $ 4,034 $ 2,877 Collateral posted $ 3,820 $ 2,801 (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 was 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) (in millions) Sept. 30, 2019 Dec. 31, 2018 If The Bank of New York Mellon’s rating changed to: (b) A3/A- $ 17 $ 15 Baa2/BBB $ 472 $ 116 Ba1/BB+ $ 2,131 $ 1,041 (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 rating by Moody’s/S&P. If The Bank of New York Mellon’s debt rating had fallen below investment grade on Sept. 30, 2019 and Dec. 31, 2018 , existing collateral arrangements would have required us to post additional collateral of $65 million and $100 million , respectively. Offsetting assets and liabilities The following tables present derivative instruments and financial instruments that are either subject to an enforceable netting agreement or offset by collateral arrangements. There were no derivative instruments or financial instruments subject to a legally enforceable netting agreement for which we are not currently netting.

We are required to pledge collateral based on predetermined terms within the agreements. If we were to experience a decline in the fair value of the collateral pledged for these transactions, we could be required to provide additional collateral to the counterparty, therefore decreasing the amount of assets available for other liquidity needs that may arise. BNY Mellon also offers tri-party collateral agency services in the tri-party repo market where we are exposed to credit risk. In order to mitigate this risk, we require dealers to fully secure intraday credit.

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 Sept. 30, 2019 Dec. 31, 2018 (in millions) Lending commitments $ 50,303 $ 50,631 Standby letters of credit (a) 2,417 2,817 Commercial letters of credit 156 165 Securities lending indemnifications (b)(c) 398,226 401,504 (a) Net of participations totaling $154 million at Sept. 30, 2019 and $163 million at Dec. 31, 2018 . (b) Excludes the indemnification for securities for which BNY Mellon acts as an agent on behalf of CIBC Mellon clients, which totaled $63 billion at Sept. 30, 2019 and $56 billion at Dec. 31, 2018 . (c) Includes cash collateral, invested in indemnified repurchase agreements, held by us as securities lending agent of $42 billion at Sept. 30, 2019 and $35 billion at Dec. 31, 2018 . 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: $31.3 billion in less than one year, $18.7 billion in one to five years and $346 million over five years. SBLCs principally support obligations of corporate clients and were collateralized with cash and securities of $166 million at Sept. 30, 2019 and $223 million at Dec. 31, 2018 . At Sept. 30, 2019 , $1.6 billion of the SBLCs will expire within one year, $783 million in one to five years and $4 million 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 Sept. 30, 2019 Dec. 31, 2018 Investment grade 90 % 89 % Non-investment grade 10 % 11 % A commercial letter of credit is normally a short-term instrument used to finance a commercial contract for the shipment of goods from a seller to a buyer. Although the commercial letter of credit is contingent upon the satisfaction of specified conditions, it represents a credit exposure if the buyer defaults on the underlying transaction. As a result, the total contractual amounts do not necessarily represent future cash requirements. Commercial letters of credit totaled $156 million at Sept. 30, 2019 and $165 million at Dec. 31, 2018 . 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 $97 million at Sept. 30, 2019 and $106 million at Dec. 31, 2018 . 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 $417 billion at Sept. 30, 2019 and $420 billion at Dec. 31, 2018 . 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 Sept. 30, 2019 and Dec. 31, 2018 , $63 billion and $56 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 $67 billion and $59 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 settlement date. At Sept. 30, 2019 , we had no unsettled repurchase agreements and $1.3 billion of unsettled reverse repurchase agreements which all settled the following day. Industry concentrations We have significant industry concentrations related to credit exposure at Sept. 30, 2019 . The tables below present our credit exposure in the financial institutions and commercial portfolios. Financial institutions portfolio exposure (in billions) Sept. 30, 2019 Loans Unfunded commitments Total exposure Securities industry $ 3.2 $ 23.4 $ 26.6 Banks 7.9 1.2 9.1 Asset managers 1.3 6.7 8.0 Insurance 0.1 2.5 2.6 Government 0.1 0.3 0.4 Other 0.8 0.8 1.6 Total $ 13.4 $ 34.9 $ 48.3 Commercial portfolio exposure (in billions) Sept. 30, 2019 Loans Unfunded commitments Total exposure Manufacturing $ 0.8 $ 4.7 $ 5.5 Services and other 0.7 3.7 4.4 Energy and utilities 0.2 3.8 4.0 Media and telecom — 1.0 1.0 Total $ 1.7 $ 13.2 $ 14.9 Major concentrations in securities lending are primarily to broker-dealers and are generally collateralized with cash and/or securities. Exposure for certain administrative errors In connection with certain offshore tax-exempt funds that we manage, we were potentially liable to the funds for certain administrative errors. The errors related to the resident status of such funds, which exposed the Company to a tax liability related to the funds’ earnings. In the third quarter of 2019, we reduced the previously established reserves for this exposure based on recent discussions and agreement with the tax authorities. Sponsored Member Repo Program BNY Mellon is a sponsoring member in the FICC sponsored member program, where we submit eligible overnight repurchase and reverse repurchase transactions in U.S. treasury 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 18 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 Sept. 30, 2019 and Dec. 31, 2018 , 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 Sept. 30, 2019 and Dec. 31, 2018 , we have not recorded any material liabilities under these arrangements. Legal proceedings In the ordinary course of business, BNY Mellon is 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, BNY Mellon establishes accruals for litigation and regulatory matters when those matters proceed to a stage where they present loss contingencies that are both probable and reasonably estimable. In such cases, there may be a possible exposure to loss in excess of any amounts accrued. BNY Mellon regularly monitors such matters for developments that could affect the amount of the accrual, and will adjust the accrual amount as appropriate. If the loss contingency in question is not both probable and reasonably estimable, BNY Mellon does not establish an accrual and the matter continues to be monitored for any developments that would make the loss contingency both probable and reasonably estimable. BNY Mellon believes that its accruals for legal proceedings are appropriate and, in the aggregate, are not material to the consolidated financial position of BNY Mellon, although future accruals could have a material effect on the results of operations in a given period. 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 $850 million in excess of the accrued liability (if any) related to those matters. The following describes certain judicial, regulatory and arbitration proceedings involving BNY Mellon: 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. Six actions remain pending in federal and 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 (“SIB”), also controlled by Stanford, issued certificates of deposit (“CDs”). Some investors allegedly wired funds from their SGC accounts to purchase CDs. In 2009, the SEC 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 15 lawsuits against Pershing that are pending in Texas, including a putative class action. The purchasers allege that Pershing, as SGC’s clearing firm, assisted Stanford in a fraudulent scheme and assert contractual, statutory and common law claims. On July 12, 2018, a federal district court dismissed six of the individual lawsuits and those cases are on appeal. On March 8, 2019, a group of investors filed a putative class action against The Bank of New York Mellon, making the same allegations as in the prior actions brought against Pershing. FINRA arbitration proceedings also have been initiated by alleged purchasers asserting similar claims. 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 has appealed that decision. 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 Feb. 4, 2016, Postalis filed a lawsuit in Brasilia against DTVM, Ativos and BNY Mellon Alocação de Patrimônio Ltda., 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 controller of Postalis’s own investment portfolio. On April 18, 2018, the court dismissed the lawsuit without prejudice, and the MPF has appealed that decision. In addition, the Tribunal de Contas da Uniao, an administrative tribunal, has initiated two proceedings with the purpose of determining liability for losses to two investment funds administered by DTVM in which Postalis was the exclusive investor. 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. 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. We have not received any tax demand concerning cum/ex trading. In addition, 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 third parties. Trial commenced in September. 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.

Segment Reporting [Abstract]
Lines of business	Lines of business We have an internal information system that produces performance data along product and service lines for our two principal businesses and the Other segment. The primary products and services and types of revenue for our principal businesses and a description of the Other segment are presented in Note 23 of the Notes to Consolidated Financial Statements in our 2018 Annual Report. Business accounting principles Our business data has been determined on an internal management basis of accounting, rather than the generally accepted accounting principles used for consolidated financial reporting. These measurement principles are designed so that reported results of the businesses will track their economic performance. Business results are subject to reclassification when organizational changes are made. There were no significant organizational changes in the third quarter of 2019 . The results are also subject to refinements in revenue and expense allocation methodologies, which are typically reflected on a prospective basis. The accounting policies of the businesses are the same as those described in Note 1 of the Notes to Consolidated Financial Statements in our 2018 Annual Report. The results of our businesses are presented and analyzed on an internal management reporting basis. • Revenue amounts reflect fee and other revenue generated by each business. Fee and other revenue transferred between businesses under revenue transfer agreements is included within other revenue in each business. • Revenues and expenses associated with specific client bases are included in those businesses. For example, foreign exchange activity associated with clients using custody products is included in Investment Services. • Net interest revenue is allocated to businesses based on the yields on the assets and liabilities generated by each business. We employ a funds transfer pricing system that matches funds with the specific assets and liabilities of each business based on their interest sensitivity and maturity characteristics. • The provision for credit losses associated with the respective credit portfolios is reflected in each business segment. • Incentives expense related to restricted stock is allocated to the businesses. • Support and other indirect expenses are allocated to businesses based on internally developed methodologies. • Recurring FDIC expense is allocated to the businesses based on average deposits generated within each business. • Litigation expense is generally recorded in the business in which the charge occurs. • Management of the securities portfolio is a shared service contained in the Other segment. As a result, gains and losses associated with the valuation of the securities portfolio are included in the Other segment. • Client deposits serve as the primary funding source for our 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. Businesses 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 businesses to our overall profitability.

Accounting Policies [Abstract]
Basis of presentation	Basis of presentation The accounting and financial reporting policies of BNY Mellon, a global financial services company, conform to U.S. GAAP and prevailing industry practices. For information on our significant accounting and reporting policies, see Note 1 in our 2018 Annual Report.
Reclassifications	Certain immaterial reclassifications have been made to prior periods to place them on a basis comparable with the current period presentation.
Use of estimates	Use of estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates based upon assumptions about future economic and market conditions which affect reported amounts and related disclosures in our financial statements. Although our current estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that actual conditions could be worse than anticipated in those estimates, which could materially affect our results of operations and financial condition. Amounts subject to estimates are items such as allowance for loan losses and lending-related commitments, fair value of financial instruments and derivatives, goodwill and other intangibles and litigation and regulatory contingencies. Among other effects, such changes in estimates could result in future impairments of goodwill and intangible assets and establishment of allowances for loan losses and lending-related commitments as well as accruals for litigation and regulatory contingencies.
Accounting changes and new accounting guidance	The following accounting changes and new accounting guidance were adopted in the first quarter of 2019. ASU 2016-02, Leases In February 2016, the FASB issued an ASU, Leases . The primary objective of this ASU is to increase transparency and comparability by recognizing lease assets and liabilities on the balance sheet and expand related disclosures. This ASU requires a “right-of-use” asset and a payment obligation liability on the balance sheet for most leases and subleases. Additionally, depending on the lease classification under the standard, it may result in different expense recognition patterns and classification than under existing accounting principles. For leases classified as finance leases, it will result in higher expense recognition in the earlier periods and lower expense in the later periods of the lease. The Company adopted this guidance on Jan. 1, 2019 using the alternative transition method on a prospective basis and recognized right-of-use assets of $1.3 billion and lease liabilities of $1.5 billion on the consolidated balance sheet, both based on the present value of the expected remaining lease payments. See Note 6 for the disclosures required by this ASU. ASU 2018-02, Income Statement—Reporting Comprehensive Income: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income In February 2018, the FASB issued an ASU, Income Statement—Reporting Comprehensive Income: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU permits a reclassification from accumulated other comprehensive income to retained earnings for the tax effects of items within accumulated other comprehensive income that do not reflect the lower statutory tax rate which was enacted by the 2017 U.S. tax legislation. BNY Mellon adopted this guidance in the first quarter of 2019, which resulted in a $90 million reclassification that decreased accumulated other comprehensive income and increased retained earnings.
Leasing	Significant accounting policy 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. We use our incremental borrowing rate based on the information available at commencement date of the lease 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. We have elected to account for the lease and non-lease components as a single lease component and exclude the non-lease variable components. Additionally, for certain equipment leases, we apply a portfolio approach to account for the operating lease ROU assets and liabilities. BNY Mellon engages in subleasing activities and reports the rental income 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.
Fair value measurement	Fair value measurement Fair 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. See Note 19 of the Notes to Consolidated Financial Statements in our 2018 Annual Report for information on how we determine fair value and the fair value hierarchy. The following tables present the financial instruments carried at fair value at Sept. 30, 2019 and Dec. 31, 2018 , 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.
