Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accounting and financial reporting policies of State Street Corporation conform to U.S. GAAP. State Street Corporation, the Parent Company, is a financial holding company headquartered in Boston, Massachusetts. Unless otherwise indicated or unless the context requires otherwise, all references in these notes to consolidated financial statements to “State Street,” “we,” “us,” “our” or similar references mean State Street Corporation and its subsidiaries on a consolidated basis, including our principal banking subsidiary, State Street Bank. The accompanying consolidated financial statements should be read in conjunction with the financial and risk factor information included in our 2021 Form 10-K, which we previously filed with the SEC. The consolidated financial statements accompanying these condensed notes are unaudited. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, which are necessary for a fair statement of the consolidated results of operations in these financial statements, have been made. Certain previously reported amounts presented in this Form 10-Q have been reclassified to conform to current-period presentation. Events occurring subsequent to the date of our consolidated statement of condition were evaluated for potential recognition or disclosure in our consolidated financial statements through the date we filed this Form 10-Q with the SEC. The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions in the application of certain of our significant accounting policies that may materially affect the reported amounts of assets, liabilities, equity, revenue and expenses. As a result of unanticipated events or circumstances, actual results could differ from those estimates. These accounting estimates reflect the best judgment of management, but actual results could differ. Our consolidated statement of condition as of December 31, 2021 included in the accompanying consolidated financial statements was derived from the audited financial statements as of that date, but does not include all notes required by U.S. GAAP for a complete set of consolidated financial statements. In September 2021, we announced that we had entered into a definitive agreement to acquire the BBH Investor Services business for $3.5 billion in cash. Recent Accounting Developments In March 2022, the SEC staff released Staff Accounting Bulletin No. 121 (SAB 121). SAB 121 expresses the views of the SEC staff regarding the accounting for obligations to safeguard crypto-assets. The guidance requires an entity that has obligations to safeguard crypto-assets held for their platform users to recognize a liability on its balance sheet, along with a corresponding asset, and provide extensive disclosures on the nature and amount of crypto-assets under custody. This guidance was adopted in the second quarter of 2022 and had no financial statement impact. We continue to evaluate the potential impact of the guidance on State Street Digital products and services currently in development. We did not adopt any other new accounting standards in the third quarter of 2022 that had a material impact to our financial statements. Relevant standards that were recently issued but not yet adopted Standard Description Date of Adoption Effects on the financial statements or other significant matters ASU 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures The standard addresses two topics: 1) eliminates the accounting guidance for TDRs, now requiring an entity to determine whether a modification results in a new loan or a continuation of an existing loan, as well as expanding disclosures related to modifications and 2) requires disclosure of current period gross write-offs of financing receivables within the vintage disclosures table. January 1, 2023, early adoption permitted We do not expect the new standard to have a significant impact as, to date, no loans have been modified in troubled debt restructurings and write-offs of financing receivables are insignificant. ASU 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method The standard makes targeted amendments to 1) expand the existing last-of-layer method to allow multiple hedging layers of a single closed portfolio (now renamed portfolio layer method), 2) expand the scope of the portfolio layer method to include nonprepayable financial assets, 3) clarify which hedging instruments are eligible for designation in a portfolio layer hedge, 4) provide additional guidance on the accounting for, and disclosure of, hedge basis adjustments that are applicable to the portfolio layer method and 5) define how hedge basis adjustments should be considered when determining credit losses for the assets included in the closed portfolio. January 1, 2023, early adoption permitted We are currently evaluating the impact of the new standard and the early adoption provisions.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Fair Value Measurements We carry trading account assets and liabilities, AFS debt securities, certain equity securities and various types of derivative financial instruments, at fair value in our consolidated statement of condition on a recurring basis. Changes in the fair values of these financial assets and liabilities are recorded either as components of our consolidated statement of income or as components of AOCI within shareholders' equity in our consolidated statement of condition. We measure fair value for the above-described financial assets and liabilities in conformity with U.S. GAAP that governs the measurement of the fair value of financial instruments. Management believes that its valuation techniques and underlying assumptions used to measure fair value conform to the provisions of U.S. GAAP. We categorize the financial assets and liabilities that we carry at fair value based on a prescribed three-level valuation hierarchy. For information about our valuation techniques for financial assets and financial liabilities measured at fair value and the fair value hierarchy, refer to pages 137 to 143 in Note 2 to the consolidated financial statements included under Item 8, Financial Statements and Supplementary Data, in our 2021 Form 10-K. The following tables present information with respect to our financial assets and liabilities carried at fair value in our consolidated statement of condition on a recurring basis as of the dates indicated: Fair Value Measurements on a Recurring Basis As of September 30, 2022 (In millions) Quoted Market Pricing Methods Pricing Methods Impact of Netting (1) Total Net Assets: Trading account assets: U.S. government securities $ 39 $ — $ — $ 39 Non-U.S. government securities — 118 — 118 Other — 528 — 528 Total trading account assets 39 646 — 685 Available-for-sale investment securities: U.S. Treasury and federal agencies: Direct obligations 7,856 — — 7,856 Mortgage-backed securities — 9,403 — 9,403 Total U.S. Treasury and federal agencies 7,856 9,403 — 17,259 Non-U.S. debt securities: Mortgage-backed securities — 1,662 — 1,662 Asset-backed securities — 1,640 — 1,640 Non-U.S. sovereign, supranational and non-U.S. agency — 13,674 — 13,674 Other — 2,084 — 2,084 Total non-U.S. debt securities — 19,060 — 19,060 Asset-backed securities: Student loans — 133 — 133 Collateralized loan obligations — 2,317 — 2,317 Non-agency CMBS and RMBS (2) — 215 — 215 Other — 88 — 88 Total asset-backed securities — 2,753 — 2,753 State and political subdivisions — 924 — 924 Other U.S. debt securities — 990 — 990 Total available-for-sale investment securities 7,856 33,130 — 40,986 Other assets: Derivative instruments: Foreign exchange contracts 2 30,117 15 $ (18,950) 11,184 Interest rate contracts — — — — — Total derivative instruments 2 30,117 15 (18,950) 11,184 Other 7 662 — — 669 Total assets carried at fair value $ 7,904 $ 64,555 $ 15 $ (18,950) $ 53,524 Liabilities: Accrued expenses and other liabilities: Derivative instruments: Foreign exchange contracts $ 4 $ 30,404 $ 8 $ (22,346) $ 8,070 Interest rate contracts 4 — — — 4 Other derivative contracts — 245 — — 245 Total derivative instruments 8 30,649 8 (22,346) 8,319 Total liabilities carried at fair value $ 8 $ 30,649 $ 8 $ (22,346) $ 8,319 (1) Represents counterparty netting against level 2 financial assets and liabilities where a legally enforceable master netting agreement exists between us and the counterparty.

The following tables present activity related to our level 3 financial assets during the three and nine months ended September 30, 2022 and 2021, respectively. Transfers into and out of level 3 are reported as of the beginning of the period presented. During both the three and nine months ended September 30, 2022, there were no transfers into and out of level 3. During the three months ended September 30, 2021, there were no transfers into level 3. During the nine months ended September 30, 2021, transfers into level 3 were primarily related to a U.S. corporate bond, for which fair value was measured using information obtained from third party sources, including non-binding broker/dealer quotes. During the three and nine months ended September 30, 2021, transfers out of level 3 were primarily related to collateralized loan obligations and a U.S. corporate bond, for which fair value was measured using prices for which observable market information became available.

Investments, Debt and Equity Securities [Abstract]
Investment Securities	Investment Securities Investment securities held by us are classified as either trading account assets, AFS, HTM or equity securities held at fair value at the time of purchase and reassessed periodically, based on management’s intent. For additional information on our accounting for investment securities, refer to page 144 in Note 3 to the consolidated financial statements included under Item 8, Financial Statements and Supplementary Data, in our 2021 Form 10-K. Trading assets are carried at fair value. Both realized and unrealized gains and losses on trading assets are recorded in foreign exchange trading services revenue in our consolidated statement of income. AFS securities are carried at fair value, with any allowance for credit losses recorded through the consolidated statement of income and after-tax net unrealized gains and losses are recorded in AOCI. Gains or losses realized on sales of AFS investment securities are computed using the specific identification method and are recorded in gains (losses) related to investment securities, net, in our consolidated statement of income. HTM investment securities are carried at cost, adjusted for amortization of premiums and accretion of discounts, with any allowance for credit losses recorded through the consolidated statement of income. The following table presents the amortized cost, fair value and associated unrealized gains and losses of AFS and HTM investment securities as of the dates indicated: September 30, 2022 December 31, 2021 Amortized Cost Gross Unrealized Fair Value Amortized Cost Gross Unrealized Fair Value (In millions) Gains Losses Gains Losses Available-for-sale: U.S. Treasury and federal agencies: Direct obligations $ 8,150 $ 13 $ 307 $ 7,856 $ 18,111 $ 24 $ 196 $ 17,939 Mortgage-backed securities 9,618 — 215 9,403 18,154 148 94 18,208 Total U.S. Treasury and federal agencies 17,768 13 522 17,259 36,265 172 290 36,147 Non-U.S. debt securities: Mortgage-backed securities 1,680 — 18 1,662 1,986 12 3 1,995 Asset-backed securities (1) 1,671 — 31 1,640 2,087 2 2 2,087 Non-U.S. sovereign, supranational and non-U.S. agency 14,142 2 470 13,674 23,533 114 100 23,547 Other (2) 2,262 — 178 2,084 3,113 17 32 3,098 Total non-U.S. debt securities 19,755 2 697 19,060 30,719 145 137 30,727 Asset-backed securities: Student loans (3) 134 — 1 133 209 2 — 211 Collateralized loan obligations (4) 2,371 — 54 2,317 2,155 2 2 2,155 Non-agency CMBS and RMBS (5) 220 — 5 215 52 — — 52 Other 90 — 2 88 90 1 — 91 Total asset-backed securities 2,815 — 62 2,753 2,506 5 2 2,509 State and political subdivisions 952 — 28 924 1,216 59 3 1,272 Other U.S. debt securities (6) 1,073 — 83 990 2,734 23 13 2,744 Total available-for-sale securities (7)(9) $ 42,363 $ 15 $ 1,392 $ 40,986 $ 73,440 $ 404 $ 445 $ 73,399 Held-to-maturity: U.S. Treasury and federal agencies: Direct obligations $ 11,637 $ — $ 353 $ 11,284 $ 2,170 $ 10 $ — $ 2,180 Mortgage-backed securities 42,967 — 6,207 36,760 33,481 362 578 33,265 Total U.S. Treasury and federal agencies 54,604 — 6,560 48,044 35,651 372 578 35,445 Non-U.S. debt securities: Non-U.S. sovereign, supranational and non-U.S. agency 6,141 — 268 5,873 1,564 — 9 1,555 Total non-U.S. debt securities 6,141 — 268 5,873 1,564 — 9 1,555 Asset-backed securities: Student loans (3) 4,238 1 104 4,135 4,908 48 14 4,942 Non-agency CMBS and RMBS (8) 249 19 — 268 307 22 — 329 Total asset-backed securities 4,487 20 104 4,403 5,215 70 14 5,271 Total held-to-maturity securities (7) $ 65,232 $ 20 $ 6,932 $ 58,320 $ 42,430 $ 442 $ 601 $ 42,271 (1) As of September 30, 2022 and December 31, 2021, the fair value includes non-U.S. collateralized loan obligations of $0.78 billion and $0.83 billion, respectively. (2) As of September 30, 2022 and December 31, 2021, the fair value includes non-U.S. corporate bonds of $1.11 billion and $1.53 billion, respectively. (3) Primarily comprised of securities guaranteed by the federal government with respect to at least 97% of defaulted principal and accrued interest on the underlying loans. (4) Excludes collateralized loan obligations in loan form. Refer to Note 4 for additional information. (5) Consists entirely of non-agency CMBS as of both September 30, 2022 and December 31, 2021. (6) As of September 30, 2022 and December 31, 2021, the fair value of U.S. corporate bonds was $0.99 billion and $2.44 billion, respectively. (7) An immaterial amount of accrued interest related to HTM and AFS investment securities was excluded from the amortized cost basis for the period ended September 30, 2022. (8) As of September 30, 2022 and December 31, 2021, the total amortized cost included $239 million and $292 million, respectively, of non-agency CMBS and $10 million and $14 million of non-agency RMBS, respectively. (9) As of both September 30, 2022 and December 31, 2021, total amortized cost included an allowance for credit losses on AFS investment securities of $1 million. Aggregate investment securities with carrying values of approximately $83.71 billion and $80.81 billion as of September 30, 2022 and December 31, 2021, respectively, were designated as pledged for public and trust deposits, short-term borrowings and for other purposes as provided by law. In the second quarter of 2022, $21.23 billion of investment securities previously classified as AFS were transferred to HTM. These transfers reflect our intent to hold these securities until their maturity. These securities were transferred at fair value, which included a net unrealized loss of $1.29 billion. Upon transfer of a debt security from AFS to HTM, the amortized cost is reset to fair value. Any net unrealized gain or loss at the date of transfer will remain in AOCI and be amortized into net interest income over the remaining life of the security. The amortization of amounts retained in AOCI will offset the effect on net interest income of the amortization of the premium or discount resulting from transferring securities at fair value.

The level rate of return considers any non-refundable fees or costs, as well as purchase premiums or discounts, adjusted as prepayments occur, resulting in amortization or accretion, accordingly. Allowance for Credit Losses on Debt Securities and Impairment of AFS Securities We conduct quarterly reviews of HTM and AFS securities on a collective (pool) basis when similar risk characteristics exist to determine whether an allowance for credit losses should be recognized. We review individual AFS securities periodically to assess if additional impairment is required. For additional information about the Current Expected Credit Loss methodology and the review of investment securities for expected credit losses or impairment, refer to pages 148 to 149 in Note 3 to the consolidated financial statements included under Item 8, Financial Statements and Supplementary Data, in our 2021 Form 10-K. We monitor the credit quality of the HTM and AFS investment securities using a variety of methods, including both external and internal credit ratings. As of September 30, 2022, 99% of our HTM and AFS investment portfolio is publicly rated investment grade. We had no allowance for credit losses on our HTM securities as of both September 30, 2022 and December 31, 2021. Our allowance for credit losses on our AFS securities was approximately $1 million and $2 million as of September 30, 2022 and December 31, 2021, respectively. In the third quarter of 2022, we recorded $1 million provision for credit losses and no charge-offs on AFS securities. We have elected to not record an allowance on accrued interest for HTM and AFS securities. Accrued interest on these securities is reversed against interest income when payment on a security is delinquent for greater than 90 days from the date of payment.

Receivables [Abstract]
Loans and Allowance for Credit Losses	Loans and Allowance for Credit Losses We segregate our loans into two segments: commercial and financial loans and commercial real estate loans. We further classify commercial and financial loans as fund finance loans, leveraged loans, overdrafts and other. These classifications reflect their risk characteristics, their initial measurement attributes and the methods we use to monitor and assess credit risk. For additional information on our loans, including our internal risk-rating system used to assess our risk of credit loss for each loan, refer to pages 149 to 154 in Note 4 to the consolidated financial statements included under Item 8, Financial Statements and Supplementary Data, in our 2021 Form 10-K. The following table presents our recorded investment in loans, by segment, as of the dates indicated: (In millions) September 30, 2022 December 31, 2021 Domestic (1) : Commercial and financial: Fund Finance (2) $ 12,094 $ 12,396 Leveraged loans 2,346 3,106 Overdrafts 2,787 1,796 Other (3) 2,133 2,262 Commercial real estate 2,921 2,554 Total domestic 22,281 22,114 Foreign (1) : Commercial and financial: Fund Finance (2) 8,454 7,778 Leveraged loans 1,006 1,328 Overdrafts 4,372 1,312 Total foreign 13,832 10,418 Total loans (2) 36,113 32,532 Allowance for credit losses (97) (87) Loans, net of allowance $ 36,016 $ 32,445 (1) Domestic and foreign categorization is based on the borrower’s country of domicile. (2) Fund finance loans include primarily $7.69 billion private equity capital call finance loans, $6.57 billion loans to real money funds, $4.25 billion collateralized loan obligations in loan form and $1.10 billion loans to business development companies as of September 30, 2022, compared to $9.15 billion private equity capital call finance loans, $6.40 billion loans to real money funds, $2.91 billion collateralized loan obligations in loan form and $1.39 billion loans to business development companies as of December 31, 2021. (3) Includes $1.73 billion securities finance loans, $389 million loans to municipalities and $19 million other loans as of September 30, 2022 and $1.78 billion securities finance loans, $455 million loans to municipalities and $23 million other loans as of December 31, 2021. The commercial and financial segment is composed of primarily fund finance loans, purchased leveraged loans, overdrafts and other loans. Fund finance loans are composed of revolving credit lines providing liquidity and leverage to mutual fund and private equity fund clients, as well as collateralized loan obligations in loan form. Certain loans are pledged as collateral for access to the Federal Reserve's discount window. As of September 30, 2022 and December 31, 2021, the loans pledged as collateral totaled $9.76 billion and $10.08 billion, respectively. As of both September 30, 2022 and December 31, 2021, we had no loans on non-accrual status. We sold $21 million of loans in the third quarter of 2022. In certain circumstances, we restructure troubled loans by granting concessions to borrowers experiencing financial difficulty. Once restructured, the loans are generally considered impaired until their maturity, regardless of whether the borrowers perform under the modified terms of the loans. There were no loans modified in troubled debt restructurings during the third quarter of 2022. Allowance for Credit Losses We recognize an allowance for credit losses in accordance with ASC 326 for certain on-balance sheet credit exposures, including financial assets held at amortized cost and off-balance sheet commitments. The allowance for credit losses is reviewed on a regular basis, and any provision for credit losses is recorded to reflect the amount necessary to maintain the allowance for expected credit losses at a level which represents what management does not expect to recover due to expected credit losses. For additional discussion on the allowance for credit losses for investment securities, please refer to Note 3, to the consolidated financial statements in this Form 10-Q. When the allowance is recorded, a provision for credit loss expense is recognized in net income. The allowance for credit losses for financial assets (excluding investment securities, as discussed in Note 3) represents the portion of the amortized cost basis, including accrued interest for financial assets held at amortized cost, which management does not expect to recover due to expected credit losses and is presented on the statement of condition as an offset to the amortized cost basis. The accrued interest balance is presented separately on the statement of condition within accrued interest and fees receivable. The allowance for off-balance sheet commitments is presented within other liabilities. The allowance for credit losses may be determined using various methods, including discounted cash flow methods, loss-rate methods, probability-of-default methods, and other quantitative or qualitative methods as determined by us. The method used to estimate expected credit losses may vary depending on the type of financial asset, our ability to predict the timing of cash flows, and the information available to us. We measure expected credit losses of financial assets on a collective (pool) basis when similar risk characteristics exist. Each reporting period, we assess whether the assets in the pool continue to display similar risk characteristics. For a financial asset that does not share risk characteristics with other assets, expected credit losses are measured separately using one or more of the methods noted above. As of September 30, 2022, we had 11 loans for $130 million in the commercial and financial segment that no longer met the similar risk characteristics of their collective pool. We recorded an allowance for credit losses of $8 million as of September 30, 2022 on these loans. Determining the appropriateness of the allowance is complex and requires judgment by management about the effect of matters that are inherently uncertain. In future periods, factors and forecasts then prevailing may result in significant changes in the allowance for credit losses in those future periods. We estimate credit losses over the contractual life of the financial asset, while factoring in prepayment activity, where supported by data, over a 3 year reasonable and supportable forecast period. We utilize a baseline, upside and downside scenario which are applied based on a probability weighting, in order to better reflect management’s expectation of expected credit losses given existing market conditions and the changes in the economic environment. The multiple scenarios are based on a three year horizon (or less depending on contractual maturity) and then revert linearly over a two year period to a ten-year historical average thereafter. The contractual term excludes expected extensions, renewals and modifications, but includes prepayment assumptions where applicable. As part of our allowance methodology, we establish qualitative reserves to address any risks inherent in our portfolio that are not addressed through our quantitative reserve assessment. These factors may relate to, among other things, legislation changes or new regulation, credit concentration, loan markets, scenario weighting and overall model limitations. The qualitative adjustments are applied to our portfolio of financial instruments under the existing governance structure and are inherently judgmental. For additional information on the allowance for credit losses, refer to pages 149 to 154 in Note 4 to the consolidated financial statements included under item 8, Financial Statements and Supplementary Data, in our 2021 Form 10-K. Credit Quality Credit quality for financial assets held at amortized cost is continuously monitored by management and is reflected within the allowance for credit losses. We use an internal risk-rating system to assess our risk of credit loss for each loan. This risk-rating process incorporates the use of risk-rating tools in conjunction with management judgment. Qualitative and quantitative inputs are captured in a systematic manner, and following a formal review and approval process, an internal credit rating based on our credit scale is assigned. When computing allowance levels, credit loss assumptions are estimated using a model that categorizes asset pools based on loss history, delinquency status and other credit trends and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. Determining the appropriateness of the allowance is complex and requires judgment by management about the effect of matters that are inherently uncertain. In future periods evaluations of the overall asset portfolio, in light of the factors and forecasts then prevailing, may result in significant changes in the allowance and credit loss expense in those future periods. Credit quality is assessed and monitored by evaluating various attributes in order to enable the earliest possible detection of any concerns with the customer’s credit rating. The results of those evaluations are utilized in underwriting new loans and transactions with counterparties and in our process for estimation of expected credit losses. In assessing the risk rating assigned to each individual loan, among the factors considered are the borrower's debt capacity, collateral coverage, payment history and delinquency experience, financial flexibility and earnings strength, the expected amounts and source of repayment, the level and nature of contingencies, if any, and the industry and geography in which the borrower operates. These factors are based on an evaluation of historical and current information, and involve subjective assessment and interpretation. Credit counterparties are evaluated and risk-rated on an individual basis at least annually. Management considers the ratings to be current as of September 30, 2022. Our internal risk rating methodology assigns risk ratings to counterparties ranging from Investment Grade, Speculative, Special Mention, Substandard, Doubtful and Loss. • Investment Grade: Counterparties with strong credit quality and low expected credit risk and probability of default. Approximately 83% of our loans were rated as investment grade as of September 30, 2022 with external credit ratings, or equivalent, of "BBB-" or better. • Speculative: Counterparties that have the ability to repay but face significant uncertainties, such as adverse business or financial circumstances that could affect credit risk or economic downturns. Loans to counterparties rated as speculative account for approximately 15% of our loans as of September 30, 2022, and are concentrated in leveraged loans. Approximately 97% of those leveraged loans have an external credit rating, or equivalent, of "BB" or "B" as of September 30, 2022. • Special Mention: Counterparties with potential weaknesses that, if uncorrected, may result in deterioration of repayment prospects. • Substandard: Counterparties with well-defined weakness that jeopardizes repayment with the possibility we will sustain some loss. • Doubtful: Counterparties with well-defined weakness which make collection or liquidation in full highly questionable and improbable. • Loss: Counterparties which are uncollectible or have little value. The following tables present our recorded loans to counterparties by risk rating, as noted above, as of the dates indicated: September 30, 2022 Commercial and Financial Commercial Real Estate Total Loans (In millions) Investment grade $ 27,617 $ 2,447 $ 30,064 Speculative 5,128 385 5,513 Special mention 317 89 406 Substandard 130 — 130 Total (1) $ 33,192 $ 2,921 $ 36,113 December 31, 2021 Commercial and Financial Commercial Real Estate Total Loans (In millions) Investment grade $ 24,974 $ 2,222 $ 27,196 Speculative 4,714 270 4,984 Special mention 118 62 180 Substandard 164 — 164 Total (1)(2) $ 29,970 $ 2,554 $ 32,524 (1) Loans Include $7.16 billion and $3.11 billion of overdrafts as of September 30, 2022 and December 31, 2021, respectively. Overdrafts are short-term in nature and do not present a significant credit risk to us. As of September 30, 2022, $5.78 billion overdrafts were investment grade and $1.37 billion overdrafts were speculative. (2) Total does not include $8 million of loans classified as held-for-sale as of December 31, 2021. For additional information about credit quality, refer to pages 151 to 154 in Note 4 to the consolidated financial statements included under Item 8, Financial Statements and Supplementary Data, in our 2021 Form 10-K. The following table presents the amortized cost basis, by year of origination and credit quality indicator, as of September 30, 2022. For origination years before the fifth annual period, we present the aggregate amortized cost basis of loans. For purchased loans, the date of issuance is used to determine the year of origination, not the date of acquisition. For modified, extended or renewed lending arrangements, we evaluate whether a credit event has occurred which would consider the loan to be a new arrangement.

Loans are reviewed on a regular basis, and any provisions for credit losses that are recorded reflect management's estimate of the amount necessary to maintain the allowance for loan losses at a level considered appropriate to absorb estimated credit losses in the loan portfolio. In the third quarter of 2022, we recorded no provision for credit losses, as a downward shift in management's economic outlook was offset by a reduction in loan portfolio risk. In the third quarter of 2021, we reduced the allowance for credit losses by $4 million, principally through a $2 million reserve release in the provision for credit losses. Allowance estimates remain subject to continued model and economic uncertainty and management may use qualitative adjustments in the allowance estimates. If future data and forecasts deviate relative to the forecasts utilized to determine our allowance for credit losses as of September 30, 2022, or if credit risk migration is higher or lower than forecasted for reasons independent of the economic forecast, our allowance for credit losses will also change.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments We use derivative financial instruments to support our clients' needs and to manage our interest rate and currency risks. These financial instruments consist of FX contracts such as forwards, futures and options contracts; interest rate contracts such as interest rate swaps (cross currency and single currency) and futures; and other derivative contracts. Derivative instruments used for risk management purposes that are highly effective in offsetting the risk being hedged are generally designated as hedging instruments in hedge accounting relationships, while others are economic hedges and not designated in hedge accounting relationships. For additional information on our use and accounting policies on derivative financial instruments, including derivatives not designated as hedging instruments, refer to pages 158 to 159 in Note 10 to the consolidated financial statements included under Item 8, Financial Statements and Supplementary Data, in our 2021 Form 10-K. Derivatives Designated as Hedging Instruments For additional information on our derivatives designated as hedging instruments, including our risk management objectives and hedging documentation methodologies, refer to page 159 in Note 10 to the consolidated financial statements included under Item 8, Financial Statements and Supplementary Data, in our 2021 Form 10-K. Fair Value Hedges Derivatives designated as fair value hedges are utilized to mitigate the risk of changes in the fair values of recognized assets and liabilities, including long-term debt and AFS securities. We use interest rate contracts in this manner to manage our exposure to changes in the fair value of hedged items caused by changes in interest rates. Changes in the fair value of the derivative and changes in fair value of the hedged item due to changes in the hedged risk are recognized in earnings in the same line item. If a hedge is terminated, but the hedged item was not derecognized, all remaining adjustments to the carrying amount of the hedged item are amortized over a period that is consistent with the amortization of other discounts or premiums associated with the hedged item . Cash Flow Hedges Derivatives designated as cash flow hedges are utilized to offset the variability of cash flows of recognized assets, liabilities or forecasted transactions. We have entered into FX contracts to hedge the change in cash flows attributable to FX movements in foreign currency denominated investment securities. Additionally, we have entered into interest rate swap agreements to hedge the forecasted cash flows associated with LIBOR indexed floating-rate loans. The interest rate swaps synthetically convert the loan interest receipts from a variable-rate to a fixed-rate, thereby mitigating the risk attributable to changes in the LIBOR benchmark rate. Changes in fair value of the derivatives designated as cash flow hedges are initially recorded in AOCI and then reclassified into earnings in the same period or periods during which the hedged forecasted transaction affects earnings and are presented in the same income statement line item as the earnings effect of the hedged item. If the hedge relationship is terminated, the change in fair value on the derivative recorded in AOCI is reclassified into earnings consistent with the timing of the hedged item. For hedge relationships that are discontinued because a forecasted transaction is not expected to occur according to the original hedge terms, any related derivative values recorded in AOCI are immediately recognized in earnings. The net loss associated with cash flow hedges expected to be reclassified from AOCI within 12 months of September 30, 2022, is approximately $233 million. The maximum length of time over which forecasted cash flows are hedged is 5 years. Net Investment Hedges Derivatives categorized as net investment hedges are entered into to protect the net investment in our foreign operations against adverse changes in exchange rates. We use FX forward contracts to convert the foreign currency risk to U.S. dollars to mitigate our exposure to fluctuations in FX rates. The changes in fair value of the FX forward contracts are recorded, net of taxes, in the foreign currency translation component of OCI. The following table presents the aggregate contractual, or notional, amounts of derivative financial instruments, including those entered into for trading and asset-and-liability management activities as of the dates indicated: (In millions) September 30, 2022 December 31, 2021 Derivatives not designated as hedging instruments: Interest rate contracts: Futures $ 1,856 $ 9,604 Foreign exchange contracts: Forward, swap and spot 2,054,428 2,569,449 Options purchased 1,032 328 Options written 697 210 Futures 1,537 2,359 Other: Stable value contracts (1) 31,749 32,868 Deferred value awards (2) 341 308 Derivatives designated as hedging instruments: Interest rate contracts: Swap agreements 24,816 15,100 Foreign exchange contracts: Forward and swap 8,387 6,700 (1) The notional value of the stable value contracts represents our maximum exposure.

Derivatives Netting and Credit Contingencies Netting Derivatives receivable and payable as well as cash collateral from the same counterparty are netted in the consolidated statement of condition for those counterparties with whom we have legally binding master netting agreements in place. In addition to cash collateral received and transferred presented on a net basis, we also receive and transfer collateral in the form of securities, which mitigate credit risk but are not eligible for netting. Additional information on netting is provided in Note 8. Credit Contingencies Certain of our derivatives are subject to master netting agreements with our derivative counterparties containing credit risk-related contingent features, which requires us to maintain an investment grade credit rating with the various credit rating agencies. If our rating falls below investment grade, we would be in violation of the provisions, and counterparties to the derivatives could request immediate payment or demand full overnight collateralization on derivatives instruments in net liability positions. The aggregate fair value of all derivatives with credit contingent features and in a liability position as of September 30, 2022 totaled approximately $7.20 billion, against which we provided $5.54 billion of collateral in the normal course of business. If our credit related contingent features underlying these agreements were triggered as of September 30, 2022, the maximum additional collateral we would be required to post to our counterparties is approximately $1.66 billion.

(8) Offsetting of repurchase agreements primarily relates to our involvement in FICC, where we settle transactions on a net basis for payment and delivery through the Fedwire system. NA Not applicable The securities transferred under resale and repurchase agreements typically are U.S. Treasury, agency and agency MBS. In our principal securities borrowing and lending arrangements, the securities transferred are predominantly equity securities and some corporate debt securities. The fair value of the securities transferred may increase in value to an amount greater than the amount received under our repurchase and securities lending arrangements, which exposes us to counterparty risk. We require the review of the price of the underlying securities in relation to the carrying value of the repurchase agreements and securities lending arrangements on a daily basis and when appropriate, adjust the cash or security to be obtained or returned to counterparties that is reflective of the required collateral levels.

Contingencies	Contingencies Legal and Regulatory Matters In the ordinary course of business, we and our subsidiaries are involved in disputes, litigation, and governmental or regulatory inquiries and investigations, both pending and threatened. These matters, if resolved adversely against us or settled, may result in monetary awards or payments, fines and penalties or require changes in our business practices. The resolution or settlement of these matters is inherently difficult to predict. Based on our assessment of these pending matters, we do not believe that the amount of any judgment, settlement or other action arising from any pending matter is likely to have a material adverse effect on our consolidated financial condition. However, an adverse outcome or development in certain of the matters described below could have a material adverse effect on our consolidated results of operations for the period in which such matter is resolved, or an accrual is determined to be required, on our consolidated financial condition, or on our reputation. We evaluate our needs for accruals of loss contingencies related to legal and regulatory proceedings on a case-by-case basis. When we have a liability that we deem probable, and we deem the amount of such liability can be reasonably estimated as of the date of our consolidated financial statements, we accrue our estimate of the amount of loss. We also consider a loss probable and establish an accrual when we make, or intend to make, an offer of settlement. Once established, an accrual is subject to subsequent adjustment as a result of additional information. The resolution of legal and regulatory proceedings and the amount of reasonably estimable loss (or range thereof) are inherently difficult to predict, especially in the early stages of proceedings. Even if a loss is probable, an amount (or range) of loss might not be reasonably estimated until the later stages of the proceeding due to many factors such as the presence of complex or novel legal theories, the discretion of governmental authorities in seeking sanctions or negotiating resolutions in civil and criminal matters, the pace and timing of discovery and other assessments of facts and the procedural posture of the matter (collectively, "factors influencing reasonable estimates"). As of September 30, 2022, our aggregate accruals for loss contingencies for legal, regulatory and related matters totaled approximately $15 million , including potential fines by government agencies and civil litigation with respect to the matters specifically discussed below. To the extent that we have established accruals in our consolidated statement of condition for probable loss contingencies, such accruals may not be sufficient to cover our ultimate financial exposure associated with any settlements or judgments. Any such ultimate financial exposure, or proceedings to which we may become subject in the future, could have a material adverse effect on our businesses, on our future consolidated financial statements or on our reputation. As of September 30, 2022, for those matters for which we have accrued probable loss contingencies (including the Invoicing Matter described below) and for other matters for which loss is reasonably possible (but not probable) in future periods, and for which we are able to estimate a range of reasonably possible loss, our estimate of the aggregate reasonably possible loss (in excess of any accrued amounts) ranges up to approximately $50 million . Our estimate with respect to the aggregate reasonably possible loss is based upon currently available information and is subject to significant judgment and a variety of assumptions and known and unknown uncertainties, which may change quickly and significantly from time to time, particularly if and as we engage with applicable governmental agencies or plaintiffs in connection with a proceeding. Also, the matters underlying the reasonably possible loss will change from time to time. As a result, actual results may vary significantly from the current estimate. In certain pending matters, it is not currently feasible to reasonably estimate the amount or a range of reasonably possible loss, and such losses, which may be significant, are not included in the estimate of reasonably possible loss discussed above. This is due to, among other factors, the factors influencing reasonable estimates described above. An adverse outcome in one or more of the matters for which we have not estimated the amount or a range of reasonably possible loss, individually or in the aggregate, could have a material adverse effect on our businesses, on our future consolidated financial statements or on our reputation. Given that our actual losses from any legal or regulatory proceeding for which we have provided an estimate of the reasonably possible loss could significantly exceed such estimate, and given that we cannot estimate reasonably possible loss for all legal and regulatory proceedings as to which we may be subject now or in the future, no conclusion as to our ultimate exposure from current pending or potential legal or regulatory proceedings should be drawn from the current estimate of reasonably possible loss. The following discussion provides information with respect to significant legal, governmental and regulatory matters. Invoicing Matter In 2015, we determined that we had incorrectly invoiced clients for certain expenses. We have reimbursed most of our affected customers for those expenses, and we have implemented enhancements to our billing processes. In connection with our enhancements to our billing processes, we continue to review historical billing practices and may from time to time identify additional remediation. In 2017, we identified an additional area of incorrect expense billing associated with mailing services in our retirement services business. We currently expect the cumulative total of our payments to customers for these invoicing errors, including the error in the retirement services business, to be at least $350 million, all of which has been paid or is accrued. However, we may identify additional remediation costs. In March 2017, a purported class action was commenced against us alleging that our invoicing practices violated duties owed to retirement plan customers under the Employee Retirement Income Security Act. We have agreed, subject to court approval, to resolve this matter and pay a cost that is within our established accruals for loss contingencies. In addition, we have received a purported class action demand letter alleging that our invoicing practices were unfair and deceptive under Massachusetts law. A class of customers, or particular customers, may assert that we have not paid to them all amounts incorrectly invoiced, and may seek double or treble damages under Massachusetts law. We resolved potential criminal claims that arose from these matters by entering into a deferred prosecution agreement with the office of the United States Attorney for the District of Massachusetts and paying a $115 million penalty in May 2021. In June 2019, we reached an agreement with the SEC to settle its claims that we violated the recordkeeping provisions of Section 34(b) of the Investment Company Act of 1940 and caused violations of Section 31(a) of the Investment Company Act and Rules 31a-1(a) and 31a-1(b) thereunder in connection with our overcharges of customers which are registered investment companies. In reaching this settlement, we neither admitted nor denied the claims contained in the SEC’s order, and agreed to pay a civil monetary penalty of $40 million . Also in June 2019, we reached an agreement with the Massachusetts Attorney General’s office to resolve its claims related to this matter. In reaching this settlement, we neither admitted nor denied the claims in the order, and agreed to pay a civil monetary penalty of $5.5 million . The SEC and Massachusetts Attorney General’s office settlements both recognize that the payment of $48.8 million in disgorgement and interest is satisfied by our direct reimbursements of our customers. We paid fines to resolve claims of the Securities Divisions of the Secretaries of the State of Massachusetts and New Hampshire. The costs associated with the settlements discussed above were within our related previously established accruals for loss contingencies. We have not resolved certain claims that may be made by the U.S. Department of Labor. We do not know whether any such claims will be brought, and there can be no assurance that any settlement of any such claims will be reached on financial terms acceptable to us or at all. The aggregate amount of penalties that may potentially be imposed upon us in connection with the resolution of any such matters is not currently known. Gomes, et al. v. State Street Corp. Eight participants in our Salary Savings Program filed a purported class action complaint in May 2021 on behalf of participants and beneficiaries who participated in the Program and invested in our proprietary investment fund options between May 2015 and the present. The complaint names the Plan Sponsor as well as the committees overseeing the Plan and their respective members as defendants, and alleges breach of fiduciary duty and violations of other duties owed to retirement plan participants under the Employee Retirement Income and Security Act. We and the other named defendants deny the alleged claims and are proceeding with a defense of the matter. Edmar Financial Company, LLC et al v. Currenex, Inc. et al In August 2021, two former Currenex clients filed a putative civil class action lawsuit in the Southern District of New York alleging antitrust violations, fraud and a civil Racketeer Influenced and Corrupt Organization Act violation against Currenex, State Street and others. Income Taxes In determining our provision for income taxes, we make certain judgments and interpretations with respect to tax laws in jurisdictions in which we have business operations. Because of the complex nature of these laws, in the normal course of our business, we are subject to challenges from U.S. and non-U.S. income tax authorities regarding the amount of income taxes due. These challenges may result in adjustments to the timing or amount of taxable income or deductions or the allocation of taxable income among tax jurisdictions. We recognize a tax benefit when it is more likely than not that our position will result in a tax deduction or credit. Unrecognized tax benefits totaled approximately $236 million and $252 million as of September 30, 2022 and December 31, 2021, respectively. We are presently under audit by a number of tax authorities. The earliest tax year open to examination in jurisdictions where we have material operations is 2013. Management believes that we have sufficiently accrued liabilities as of September 30, 2022 for potential tax exposures.

Interests in Investment Funds As of both September 30, 2022 and December 31, 2021, we had no consolidated funds. As of both September 30, 2022 and December 31, 2021, we managed certain funds, considered VIEs, in which we held a variable interest but for which we were not deemed to be the primary beneficiary. Our potential maximum loss exposure related to these unconsolidated funds totaled $15 million and $17 million as of September 30, 2022 and December 31, 2021, respectively, and represented the carrying value of our investments, which are recorded in other assets in our consolidated statement of condition. The amount of loss we may recognize during any period is limited to the carrying amount of our investments in the unconsolidated funds. We also held investments in low-income housing, production and investment tax credit entities, considered VIEs for which we were not deemed to be the primary beneficiary. As of September 30, 2022 and December 31, 2021, our potential maximum loss exposure related to these unconsolidated entities totaled $1.66 billion and $1.69 billion, respectively, most of which represented the carrying value of our investments, which are recorded in other assets in our consolidated statement of condition.

These dividends total approximately $11 million, $4 million, $7 million and $14 million on our series D, F, G and H preferred stock, respectively, which will be paid in December 2022. Common Stock In September 2021, we completed a public offering of approximately 21.7 million shares of our common stock. The offering price was $87.60 per share and net proceeds totaled approximately $1.9 billion. We expect to use these net proceeds to finance our proposed acquisition of the BBH Investor Services business. In December 2020, the Federal Reserve issued results of 2020 resubmission stress tests and authorized us to continue to pay common stock dividends at current levels and to resume repurchasing common shares in the first quarter of 2021. In January 2021, our Board authorized a share repurchase program for the repurchase of up to $475 million of our common stock through March 31, 2021. In April 2021, our Board authorized a share repurchase program for the repurchase of up to $425 million of our common stock through June 30, 2021, consistent with the limit set by the Federal Reserve. In July 2021, our Board authorized a share repurchase program for the repurchase of up to $3.0 billion of our common stock through the end of 2022. In connection with our proposed acquisition of the BBH Investor Services business, we did not repurchase any common stock during the last half of 2021, as well as during the first nine months of 2022. We intend to repurchase approximately $1.0 billion of our common stock in the fourth quarter of 2022 under the existing share repurchase program, expiring December 21, 2022.

As of September 30, 2022, we and State Street Bank exceeded all regulatory capital adequacy requirements to which we were subject to. As of September 30, 2022, State Street Bank was categorized as “well capitalized” under the applicable regulatory capital adequacy framework, and exceeded all “well capitalized” ratio guidelines to which it was subject.

(2) Under the advanced approaches, credit risk RWA includes a CVA which reflects the risk of potential fair value adjustments for credit risk reflected in our valuation of OTC derivative contracts. We used a simple CVA approach in conformity with the Basel III advanced approaches. (3) Under the current advanced approaches rules and regulatory guidance concerning operational risk models, RWA attributable to operational risk can vary substantially from period-to-period, without direct correlation to the effects of a particular loss event on our results of operations and financial condition and impacting dates and periods that may differ from the dates and periods as of and during which the loss event is reflected in our financial statements, with the timing and categorization dependent on the processes for model updates and, if applicable, model revalidation and regulatory review and related supervisory processes. An individual loss event can have a significant effect on the output of our operational RWA under the advanced approaches depending on the severity of the loss event and its categorization among the seven Basel-defined UOMs. (4) Minimum requirements include a CCB of 2.5% and a SCB of 2.5% for the advanced approaches and the standardized approach, respectively, a G-SIB surcharge of 1.0% and a countercyclical buffer of 0%.

Segments, Geographical Areas [Abstract]
Non-U.S. Activities	Non-U.S. Activities We define our non-U.S. activities as those revenue-producing business activities that arise from clients which are generally serviced or managed outside the U.S. Due to the integrated nature of our business, precise segregation of our U.S. and non-U.S. activities is not possible. Subjective estimates, assumptions and other judgments are applied to quantify the financial results and assets related to our non-U.S. activities, including our application of funds transfer pricing, our asset and liability management policies and our allocation of certain indirect corporate expenses. Management periodically reviews and updates its processes for quantifying the financial results and assets related to our non-U.S. activities. The following table presents our U.S. and non-U.S. financial results for the periods indicated: Three Months Ended September 30, 2022 2021 (In millions) Non-U.S. (1) U.S. Total Non-U.S. (1) U.S. Total Total revenue $ 1,216 $ 1,743 $ 2,959 $ 1,337 $ 1,653 $ 2,990 Income before income tax expense 311 538 849 410 466 876 Nine Months Ended September 30, 2022 2021 (In millions) Non-U.S. (1) U.S. Total Non-U.S. (1) U.S. Total Total revenue $ 3,903 $ 5,090 $ 8,993 $ 4,002 $ 4,972 $ 8,974 Income before income tax expense 1,059 1,379 2,438 1,146 1,295 2,441 (1) Geographic mix is generally based on the domicile of the entity servicing the funds and is not necessarily representative of the underlying asset mix. Management fees generated outside the U.S. were approximately 25% and 26% of total management fees in the three and nine months ended September 30, 2022, respectively, compared to approximately 26% in both the three and nine months ended September 30, 2021. Servicing fees generated outside the U.S. were approximately 45% and 46% of total servicing fees in the three and nine months ended September 30, 2022, respectively, compared to approximately 48% in both the three and nine months ended September 30, 2021. Non-U.S. assets were $91.23 billion and $96.28 billion as of September 30, 2022 and 2021, respectively.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2022
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accounting and financial reporting policies of State Street Corporation conform to U.S. GAAP. State Street Corporation, the Parent Company, is a financial holding company headquartered in Boston, Massachusetts. Unless otherwise indicated or unless the context requires otherwise, all references in these notes to consolidated financial statements to “State Street,” “we,” “us,” “our” or similar references mean State Street Corporation and its subsidiaries on a consolidated basis, including our principal banking subsidiary, State Street Bank.
Consolidation	The consolidated financial statements accompanying these condensed notes are unaudited. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, which are necessary for a fair statement of the consolidated results of operations in these financial statements, have been made. Certain previously reported amounts presented in this Form 10-Q have been reclassified to conform to current-period presentation. Events occurring subsequent to the date of our consolidated statement of condition were evaluated for potential recognition or disclosure in our consolidated financial statements through the date we filed this Form 10-Q with the SEC.
Use of Estimates	The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions in the application of certain of our significant accounting policies that may materially affect the reported amounts of assets, liabilities, equity, revenue and expenses. As a result of unanticipated events or circumstances, actual results could differ from those estimates. These accounting estimates reflect the best judgment of management, but actual results could differ. Our consolidated statement of condition as of December 31, 2021 included in the accompanying consolidated financial statements was derived from the audited financial statements as of that date, but does not include all notes required by U.S. GAAP for a complete set of consolidated financial statements.
Recent Accounting Developments	Recent Accounting Developments In March 2022, the SEC staff released Staff Accounting Bulletin No. 121 (SAB 121). SAB 121 expresses the views of the SEC staff regarding the accounting for obligations to safeguard crypto-assets. The guidance requires an entity that has obligations to safeguard crypto-assets held for their platform users to recognize a liability on its balance sheet, along with a corresponding asset, and provide extensive disclosures on the nature and amount of crypto-assets under custody. This guidance was adopted in the second quarter of 2022 and had no financial statement impact. We continue to evaluate the potential impact of the guidance on State Street Digital products and services currently in development. We did not adopt any other new accounting standards in the third quarter of 2022 that had a material impact to our financial statements. Relevant standards that were recently issued but not yet adopted Standard Description Date of Adoption Effects on the financial statements or other significant matters ASU 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures The standard addresses two topics: 1) eliminates the accounting guidance for TDRs, now requiring an entity to determine whether a modification results in a new loan or a continuation of an existing loan, as well as expanding disclosures related to modifications and 2) requires disclosure of current period gross write-offs of financing receivables within the vintage disclosures table. January 1, 2023, early adoption permitted We do not expect the new standard to have a significant impact as, to date, no loans have been modified in troubled debt restructurings and write-offs of financing receivables are insignificant. ASU 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method The standard makes targeted amendments to 1) expand the existing last-of-layer method to allow multiple hedging layers of a single closed portfolio (now renamed portfolio layer method), 2) expand the scope of the portfolio layer method to include nonprepayable financial assets, 3) clarify which hedging instruments are eligible for designation in a portfolio layer hedge, 4) provide additional guidance on the accounting for, and disclosure of, hedge basis adjustments that are applicable to the portfolio layer method and 5) define how hedge basis adjustments should be considered when determining credit losses for the assets included in the closed portfolio. January 1, 2023, early adoption permitted We are currently evaluating the impact of the new standard and the early adoption provisions.
Fair Value Measurements	Fair Value Measurements We carry trading account assets and liabilities, AFS debt securities, certain equity securities and various types of derivative financial instruments, at fair value in our consolidated statement of condition on a recurring basis. Changes in the fair values of these financial assets and liabilities are recorded either as components of our consolidated statement of income or as components of AOCI within shareholders' equity in our consolidated statement of condition. We measure fair value for the above-described financial assets and liabilities in conformity with U.S. GAAP that governs the measurement of the fair value of financial instruments. Management believes that its valuation techniques and underlying assumptions used to measure fair value conform to the provisions of U.S. GAAP. We categorize the financial assets and liabilities that we carry at fair value based on a prescribed three-level valuation hierarchy. For information about our valuation techniques for financial assets and financial liabilities measured at fair value and the fair value hierarchy, refer to pages 137 to 143 in Note 2 to the consolidated financial statements included under Item 8, Financial Statements and Supplementary Data, in our 2021 Form 10-K.

Investments Classified by Contractual Maturity Date	The following table presents the amortized cost and the fair value of contractual maturities of debt investment securities as of September 30, 2022.

(2) Under the advanced approaches, credit risk RWA includes a CVA which reflects the risk of potential fair value adjustments for credit risk reflected in our valuation of OTC derivative contracts. We used a simple CVA approach in conformity with the Basel III advanced approaches. (3) Under the current advanced approaches rules and regulatory guidance concerning operational risk models, RWA attributable to operational risk can vary substantially from period-to-period, without direct correlation to the effects of a particular loss event on our results of operations and financial condition and impacting dates and periods that may differ from the dates and periods as of and during which the loss event is reflected in our financial statements, with the timing and categorization dependent on the processes for model updates and, if applicable, model revalidation and regulatory review and related supervisory processes. An individual loss event can have a significant effect on the output of our operational RWA under the advanced approaches depending on the severity of the loss event and its categorization among the seven Basel-defined UOMs. (4) Minimum requirements include a CCB of 2.5% and a SCB of 2.5% for the advanced approaches and the standardized approach, respectively, a G-SIB surcharge of 1.0% and a countercyclical buffer of 0%.

(2) Represents equity-based awards outstanding but not included in the computation of diluted average common shares, because their effect was anti-dilutive. Additional information about equity-based awards is provided on pages 173 and 175 in Note 18 to the consolidated financial statements included under Item 8, Financial Statements and Supplementary Data, in our 2021 Form 10-K. (3) Calculations reflect allocation of earnings to participating securities using the two-class method, as this computation is more dilutive than the treasury stock method.
