Significant Accounting Policies

Accounting Policies [Abstract]
Significant Accounting Policies	2 . Significant Accounting Policies Basis of Presentation These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and include the accounts of the Company and its controlled subsidiaries. Noncontrolling interests (“NCI”) on the consolidated statements of financial condition represent the portion of consolidated sponsored investment products (“CIPs”) and a consolidated affiliate (collectively, “consolidated entities”) in which the Company does not have direct equity ownership. Intercompany balances and transactions have been eliminated upon consolidation. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting periods. Actual results could differ from those estimates. Certain prior period presentations and disclosures, while not required to be recast, may be reclassified to ensure comparability with current period classifications. Accounting Developments Segment Reporting. In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Improvements to Reportable Segment Disclosures (“ASU 2023-07”), which requires incremental disclosures about reportable segments but does not change the definition of a segment or the guidance for determining reportable segments. The new guidance requires disclosure of significant segment expenses that are (1) regularly provided to (or easily computed from information regularly provided to) the chief operating decision maker ("CODM") and (2) included in the reported measure of segment profit or loss. The new standard also requires companies to disclose the title and position of the individual (or the name of the committee) identified as the CODM, allows companies to disclose multiple measures of segment profit or loss if those measures are used to assess performance and allocate resources, and is applicable to companies with a single reportable segment. The requirements are effective for annual reporting periods beginning on January 1, 2024, and are required to be applied retrospectively. Early adoption is permitted. The Company does not expect the additional disclosure requirements under ASU 2023-07 to have a material impact on the consolidated financial statements. Income Tax Disclosure Requirements. In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures (“ASU 2023-09”), which enhances interim and annual income tax disclosures. The two primary enhancements disaggregate existing income tax disclosures related to the effective tax rate reconciliation and income taxes paid. The additional disclosure requirements under ASU 2023-09 are required to be applied prospectively and are effective for the Company on January 1, 2025. The Company does not expect the additional disclosure requirements under ASU 2023-09 to have a material impact on the consolidated financial statements. Cash and Cash Equivalents . Cash and cash equivalents primarily consists of cash, money market funds and short-term, highly liquid investments with original maturities of three months or less. Cash and cash equivalent balances that are legally restricted from use by the Company are recorded in other assets on the consolidated statements of financial condition. Cash balances maintained by consolidated VIEs and voting rights entities (“VREs”) are not considered legally restricted and are included in cash and cash equivalents on the consolidated statements of financial condition. Investments Investments in Debt Securities. The Company classifies debt investments as held-to-maturity or trading based on the Company’s intent and ability to hold the debt security to maturity or its intent to sell the security. Held-to-maturity securities are purchased with the positive intent and ability to be held to maturity and are recorded at amortized cost on the consolidated statements of financial condition. Trading securities are those investments that are purchased principally for the purpose of selling them in the near term. Trading securities are carried at fair value on the consolidated statements of financial condition with changes in the fair value recorded through net income (“FVTNI”) within nonoperating income (expense). Trading securities include certain investments in collateralized loan obligations (“CLOs”) for which the fair value option is elected in order to reduce operational complexity of bifurcating embedded derivatives. Investments in Equity Securities. Equity securities are generally carried at fair value on the consolidated statements of financial condition with changes in the FVTNI within nonoperating income (expense). For nonmarketable equity securities, the Company generally elects to apply the practicality exception to fair value measurement, under which such securities will be measured at cost, less impairment, plus or minus observable price changes for identical or similar securities of the same issuer with such changes recorded through net income within nonoperating income (expense). Dividends received are recorded as dividend income within nonoperating income (expense). Equity Method. The Company applies the equity method of accounting for equity investments where the Company does not consolidate the investee, but can exert significant influence over the financial and operating policies of the investee. The evaluation of whether the Company exerts control or significant influence over the financial and operational policies of its investees is based on the facts and circumstances surrounding each individual investment. Factors considered in these evaluations may include the type of investment, the legal structure of the investee, the terms of BlackRock's contractual agreements, including investor voting or other rights, any influence BlackRock may have on the governing board of the investee, the legal rights of other investors in the entity pursuant to the entity’s operating documents and the relationship between BlackRock and other investors in the entity. The Company’s share of the investee’s underlying net income or loss is recorded as net gain (loss) on investments within nonoperating income (expense) and as other revenue for certain strategic minority investments since such investees are considered to be an extension of the Company’s core business. The Company’s share of net income of the investee is recorded based upon the most current information available at the time, which may precede the date of the consolidated statement of financial condition. Distributions received reduce the Company’s carrying value of the investment and the cost basis if deemed to be a return of capital. The Company classifies distributions in the consolidated statements of cash flows as either distributions of earnings (operating) or distributions of capital (investing) based on the nature of the distribution. Impairments of Investments. Management periodically assesses equity method, nonmarketable investments, and held-to-maturity investments for impairment. If impairment exists, an impairment charge would be recorded for the excess of the carrying amount of the investment over its estimated fair value in the consolidated statements of income. For equity method investments and nonmarketable investments, impairment evaluation considers qualitative factors, including the financial conditions and specific events related to an investee, that may indicate the fair value of the investment is less than its carrying value. For held-to-maturity investments, impairment is evaluated using market values, where available, or the expected future cash flows of the investment. For the Company’s investments in CLOs, the Company reviews cash flow estimates over the life of each CLO investment. On a quarterly basis, if the present value of the estimated future cash flows is lower than the carrying value of the investment and there is an adverse change in estimated cash flows, an impairment is considered to be other-than-temporary. Consolidation. The Company performs an analysis for investment products to determine if the product is a VIE or a VRE. Factors considered in this analysis include the entity’s legal organization, the entity’s capital structure, the rights of equity investment holders and the Company’s contractual involvement with, and economic interest in, the entity and any related party or de facto agent implications of the Company’s involvement with the entity. Entities that are determined to be VIEs are consolidated if the Company is the primary beneficiary (“PB”) of the entity. VREs are typically consolidated if the Company holds the majority voting interest. Upon the occurrence of certain events (such as contributions and redemptions, either by the Company, or third parties, or amendments to an entity’s governing documents), management reviews and reconsiders its previous conclusion regarding the status of an entity as a VIE or a VRE. Consolidation of Variable Interest Entities . Certain investment products for which a controlling financial interest is achieved through arrangements that do not involve or are not directly linked to voting interests are deemed consolidated VIEs. BlackRock reviews factors, including whether or not (1) the entity has equity at risk that is sufficient to permit the entity to finance its activities without additional subordinated support from other parties and (2) the equity holders at risk have the obligation to absorb losses, the right to receive residual returns, and the right to direct the activities of the entity that most significantly impact the entity’s economic performance, to determine if the investment product is a VIE. The PB of a VIE is defined as the variable interest holder that has a controlling financial interest in the VIE. A controlling financial interest is defined as (1) the power to direct the activities of the VIE that most significantly impact its economic performance and (2) the obligation to absorb losses of the entity or the right to receive benefits from the entity that potentially could be significant to the VIE. The Company generally consolidates VIEs in which it holds an economic interest of 10 % or greater and deconsolidates such VIEs once economic interest falls below 10 %. Management continually reconsiders whether the Company is deemed to be a VIE’s PB. Consolidation of Voting Rights Entities . BlackRock is required to consolidate an investee to the extent that BlackRock can exert absolute control over the financial and operating policies of the investee, which generally exists if there is a greater than 50% voting equity interest. Retention of Specialized Investment Company Accounting Principles. Upon consolidation of sponsored investment products, the Company retains the specialized investment company accounting principles of the underlying funds. All of the underlying investments held by such CIPs are carried at fair value with corresponding changes in the investments’ fair values reflected in net income within nonoperating income (expense). When the Company no longer controls these funds due to reduced ownership percentage or other reasons, the funds are deconsolidated and accounted for as an equity method investment or equity securities FVTNI. Separate Account Assets and Liabilities . Separate account assets are maintained by BlackRock Life Limited, a wholly owned subsidiary of the Company, which is a registered life insurance company in the United Kingdom ("UK"), and represent segregated assets held for purposes of funding individual and group pension contracts. The life insurance company does not underwrite any insurance contracts that involve any insurance risk transfer from the insured to the life insurance company. The separate account assets primarily include equity securities, debt securities, money market funds and derivatives. The separate account assets are not subject to general claims of the creditors of BlackRock. These separate account assets and the related equal and offsetting liabilities are recorded as separate account assets and separate account liabilities on the consolidated statements of financial condition. The net investment income attributable to separate account assets supporting individual and group pension contracts accrues directly to the contract owner and is not reported on the consolidated statements of income. While BlackRock has no economic interest in these separate account assets and liabilities, BlackRock earns policy administration and management fees associated with these products, which are included in investment advisory, administration fees and securities lending revenue on the consolidated statements of income. Separate Account Collateral Assets Held and Liabilities Under Securities Lending Agreements. The Company facilitates securities lending arrangements whereby securities held by separate accounts maintained by BlackRock Life Limited are lent to third parties under global master securities lending agreements. In exchange, the Company receives collateral by obtaining either (1) legal title or (2) first ranking priority security interest. The minimum collateral values generally range from approximately 102 % to 112 % of the value of the securities lent in order to reduce counterparty risk. The required collateral value is calculated on a daily basis. The global master securities lending agreements provide the Company the right to request additional collateral or, in the event of borrower default, the right to liquidate collateral. The securities lending transactions entered into by the Company are accompanied by an agreement that entitles the Company to request the borrower to return the securities at any time; therefore, these transactions are not reported as sales. In situations where the Company receives the legal title to collateral under these securities lending arrangements, the Company records an asset on the consolidated statements of financial condition and an equal collateral liability for the obligation to return the collateral. Additionally, in situations where the Company obtains a first ranking priority security interest in the collateral, the Company does not have the ability to pledge or resell the collateral and therefore does not record the collateral on the consolidated statements of financial condition. At December 31, 2023 and 2022 , the fair value of loaned securities held by separate accounts was approximately $ 9.3 billion and $ 10.2 billion, respectively, and the fair value of the collateral under these securities lending agreements was approximately $ 10.1 billion and $ 11.0 billion, respectively, of which approximately $ 4.6 billion as of 2023 and $ 5.8 billion as of 2022 was recognized on the consolidated statements of financial condition. During 2023 and 2022 , the Company had no t resold or repledged any of the collateral received under these arrangements. The securities lending revenue earned from lending securities held by the separate accounts is included in investment advisory, administration fees and securities lending revenue on the consolidated statements of income. Property and Equipment . Property and equipment are recorded at cost less accumulated depreciation. Depreciation is generally determined by cost less any estimated residual value using the straight-line method over the estimated useful lives of the various classes of property and equipment. Leasehold improvements are amortized using the straight-line method over the shorter of the estimated useful life or the remaining lease term. The Company capitalizes certain costs incurred in connection with developing or obtaining software within property and equipment. Capitalized software costs are amortized, beginning when the software product is ready for its intended use, over the estimated useful life of the software of approximately three years . Goodwill and Intangible Assets . Goodwill represents the cost of a business acquisition in excess of the fair value of the net assets acquired. The Company has determined that it has one reporting unit for goodwill impairment testing purposes, the consolidated BlackRock single operating segment, which is consistent with internal management reporting and management's oversight of operations. The Company performs an impairment assessment of its goodwill at least annually, as of July 31st. In its assessment of goodwill for impairment, the Company considers such factors as the book value and market capitalization of the Company. Intangible assets are comprised of indefinite-lived intangible assets and finite-lived intangible assets acquired in a business acquisition. The value of contracts to manage assets in proprietary open-end funds and collective trust funds and certain other commingled products without a specified termination date is generally classified as indefinite-lived intangible assets. In addition, trade names/trademarks are considered indefinite-lived intangible assets when they are expected to generate cash flows indefinitely. Indefinite-lived intangible assets and goodwill are not amortized. Finite-lived investor/customer relationships, technology-related assets, and management contracts, which relate to acquired separate accounts and funds, that are expected to contribute to the future cash flows of the Company for a specified period of time, are amortized over their estimated useful lives. On a quarterly basis, the Company considers whether the indefinite-lived and finite-lived classifications are still appropriate. The Company performs assessments to determine if any intangible assets are potentially impaired at least annually, as of July 31st. The carrying value of finite-lived assets and their remaining useful lives are reviewed to determine if circumstances exist which may indicate a potential impairment or revisions to the amortization period. In evaluating whether it is more likely than not that the fair value of indefinite-lived intangibles is less than its carrying value, BlackRock assesses various significant quantitative factors, including assets under management (“AUM”), revenue basis points, projected AUM growth rates, operating margins, tax rates and discount rates. If an indefinite-lived intangible is determined to be more likely than not impaired, then the fair value of the asset is compared with its carrying value and any excess of the carrying value over the fair value would be recognized as an expense in the period in which the impairment occurs. For finite-lived intangible assets, if potential impairment circumstances are considered to exist, the Company will perform a recoverability test using an undiscounted cash flow analysis. If the carrying value of the asset is determined not to be recoverable based on the undiscounted cash flow test, the difference between the carrying value of the asset and its current fair value would be recognized as an expense in the period in which the impairment occurs. Consolidated Affiliate. The Company owns 50.1 % of an asset management company in China - BlackRock CCB Wealth Management Company Ltd. (“WMC”). The Company consolidates WMC, which it deems to be a VRE, because it exerts control over the financial and operating policies of the entity, based on the Company’s 50.1 % ownership and voting rights. Noncontrolling Interests. NCI consist of third-party investments in the Company’s CIPs (“NCI – CIPs”) and the WMC. The Company reports NCI in stockholders’ equity, separate from the parent’s equity, on the consolidated statements of financial condition. NCI that are redeemable at the option of the holders are classified as temporary equity at estimated redemption value and nonredeemable NCI are classified as a component of permanent equity in the consolidated statements of financial condition. In addition, the Company reports net income (loss) attributable to redeemable and nonredeemable NCI holders in net income (loss) attributable to NCI in the consolidated statements of income. Treasury Stock . The Company records common stock purchased for treasury at cost. At the date of subsequent reissuance, the treasury stock account is reduced by the cost of such stock using the average cost method. Revenue Recognition. Revenue is recognized upon transfer of control of promised services to customers in an amount to which the Company expects to be entitled in exchange for those services. The Company enters into contracts that can include multiple services, which are accounted for separately if they are determined to be distinct. Consideration for the Company’s services is generally in the form of variable consideration because the amount of fees is subject to market conditions that are outside of the Company’s influence. The Company includes variable consideration in revenue when it is no longer probable of significant reversal, i.e. when the associated uncertainty is resolved. For some contracts with customers, the Company has discretion to involve a third party in providing services to the customer. Generally, the Company is deemed to be the principal in these arrangements because the Company controls the promised services before they are transferred to customers, and accordingly presents the revenue gross of related costs. Investment Advisory, Administration Fees and Securities Lending Revenue. Investment advisory and administration fees are recognized as the services are performed over time because the customer is receiving and consuming the benefits as they are provided by the Company. Fees are primarily based on agreed-upon percentages of AUM and recognized for services provided during the period, which are distinct from services provided in other periods. Such fees are affected by changes in AUM, including market appreciation or depreciation, foreign exchange translation and net inflows or outflows. Investment advisory and administration fees for investment funds are shown net of fee waivers. In addition, the Company may contract with third parties to provide sub-advisory services on its behalf. The Company presents the investment advisory fees and associated costs to such third-party advisors on a gross basis where it is deemed to be the principal and on a net basis where it is deemed to be the agent. Management judgment involved in making these assessments is focused on ascertaining whether the Company is primarily responsible for fulfilling the promised service. The Company also earns revenue by lending securities on behalf of clients, primarily to highly rated banks and broker-dealers. The securities loaned are collateralized by either cash or securities, generally ranging from 102 % to 112 % of the value of the loaned securities. Securities lending fees are based on (1) a percentage of the notional value of the loaned securities and (2) a spread between the interest earned on the reinvested cash collateral and the amount rebated to the borrower. Revenue is recognized over time as services are performed. Generally, the securities lending fees are shared between the Company and the funds or other third-party accounts managed by the Company from which the securities are borrowed. For 2023, 2022 and 2021 , securities lending revenue earned by the Company totaled $ 675 million, $ 599 million and $ 555 million, respectively, and is recorded in investment advisory, administration and securities lending revenue on the consolidated statements of income. Investment advisory, administration fees and securities lending revenue are reported together as the fees for these services often are agreed upon with clients as a bundled fee. Money Market Fee Waivers. The Company may voluntarily waive a portion of its management fees on certain money market funds to ensure that they maintain a targeted level of daily net investment income (the “Yield Support waivers”). There were no Yield Support waivers during 2023. During 2022 and 2021 , these waivers resulted in a reduction of management fees of approximately $ 72 million, and $ 500 million respectively, which was partially offset by a reduction of BlackRock’s distribution and servicing costs paid to financial intermediaries. The Company may increase or decrease the level of Yield Support waivers in future periods. Investment Advisory Performance Fees / Carried Interest. The Company receives investment advisory performance fees, including incentive allocations (carried interest) from certain actively managed investment funds and certain separately managed accounts. These performance fees are dependent upon exceeding specified relative or absolute investment return thresholds, which vary by product or account, and include monthly, quarterly, annual or longer measurement periods. Performance fees, including carried interest, are generated on certain management contracts when performance hurdles are achieved. Such performance fees are recognized when the contractual performance criteria have been met and when it is determined that they are no longer probable of significant reversal. Given the unique nature of each fee arrangement, contracts with customers are evaluated on an individual basis to determine the timing of revenue recognition. Significant judgment is involved in making such determination. Performance fees typically arise from investment management services that began in prior reporting periods. Consequently, a portion of the fees the Company recognizes may be partially related to the services performed in prior periods that meet the recognition criteria in the current period. At each reporting date, the Company considers various factors in estimating performance fees to be recognized, including carried interest. The Company is allocated carried interest from certain alternative investment products upon exceeding performance thresholds. The Company may be required to reverse/return all, or part, of such carried interest allocations/distributions depending upon future performance of these funds. Carried interest subject to such clawback provisions is recorded in investments or cash and cash equivalents to the extent that it is distributed, on its consolidated statements of financial condition. The Company records a liability for deferred carried interest to the extent it receives cash or capital allocations related to carried interest prior to meeting the revenue recognition criteria. A portion of the deferred carried interest may also be paid to certain employees. The ultimate timing of the recognition of performance fee revenue and related compensation expense, if any, is unknown. Technology services revenue. The Company offers investment management technology systems, risk management services, wealth management and digital distribution tools, all on a fee basis. Clients include banks, insurance companies, official institutions, pension funds, asset managers, retail distributors and other investors. Fees earned for technology services are primarily recorded as services are performed over time and are generally determined using the value of positions on the Aladdin platform, or on a fixed-rate basis. Revenue derived from the sale of software licenses is recognized upon the granting of access rights. Distribution Fees. The Company earns distribution and service fees related to distributing investment products and shareholder support services for investment portfolios. Distribution fees are passed-through to third-party distributors, which perform various fund distribution services and shareholder servicing of certain funds on the Company’s behalf, and are recognized as distribution and servicing costs. The Company presents distribution fees and related distribution and servicing costs incurred on a gross basis. Distribution fees primarily consist of ongoing distribution fees, shareholder servicing fees and upfront sales commissions for serving as the principal underwriter and/or distributor for certain managed mutual funds. The service of distribution is satisfied at the point in time when an investor makes an investment in a share class of the managed mutual funds. Fees are generally considered variable consideration because they are based on the value of AUM and are uncertain on trade date. Accordingly, the Company recognizes distribution fees when the amounts become known and the portion recognized in the current period may relate to distribution services performed in prior periods. Upfront sales commissions are recognized on a trade date basis. Shareholder servicing fees are based on AUM and recognized in revenue as the services are performed. Advisory and other revenue. Advisory and other revenue primarily includes fees earned for advisory services, fees earned for transition management services primarily comprised of commissions recognized in connection with buying and selling securities on behalf of customers, and equity method investment earnings related to certain strategic minority investments. Advisory services fees are determined using fixed-rate fees and are recognized over time as the related services are completed. Commissions related to transition management services are recorded on a trade-date basis as transactions occur. Stock-based Compensation . The Company recognizes compensation cost for equity classified awards based on the grant-date fair value of the award. The compensation cost is recognized over the period during which an employee is required to provide service (usually the vesting period) in exchange for the stock-based award. The Company measures the grant-date fair value of restricted stock units (“RSUs”) using the Company’s stock price on the date of grant. Stock-based awards may have performance, market and/or service conditions. For employee stock options and awards with market conditions, the Company uses pricing models. Compensation cost for awards containing performance conditions is recognized if it is probable that the conditions will be achieved. The probability of achievement is assessed on a quarterly basis. If a stock-based award is modified after the grant-date, incremental compensation cost is recognized for an amount equal to the excess of the fair value of the modified award over the fair value of the original award immediately before the modification. Awards under the Company’s stock-based compensation plans vest over various periods. Compensation cost is recorded by the Company on a straight-line basis over the requisite service period for each separate vesting portion of the award as if the award is, in-substance, multiple awards and is adjusted for actual forfeitures as they occur. The Company amortizes the grant-date fair value of stock-based compensation awards made to retirement-eligible employees over the requisite service period. Upon notification of retirement, the Company accelerates the unamortized portion of the award over the contractually required retirement notification period. The Company recognizes all excess tax benefits and deficiencies in income tax expense on the consolidated statements of income, which results in volatility of income tax expense as a result of fluctuations in the Company’s stock price. Accordingly, the Company recorded a discrete income tax benefit of $ 41 million, $ 87 million and $ 43 million during 2023, 2022 and 2021 , respectively, for vested RSUs where the grant date stock price was lower than the vesting date stock price. Distribution and Servicing Costs . Distribution and servicing costs include payments to third parties, primarily associated with distribution and servicing of client investments in certain BlackRock products. Distribution and servicing costs are expensed as incurred. Direct Fund Expense . Direct fund expense, which is expensed as incurred, primarily consists of third-party nonadvisory expense incurred by BlackRock related to certain investment products for the use of certain index trademarks, reference data for certain indices, custodial services, fund administration, fund accounting, transfer agent services, shareholder reporting services, audit and tax services as well as other fund-related expense directly attributable to the nonadvisory operations of the fund. Leases . The Company determines if a contract is a lease or contains a lease at inception. The Company accounts for its office facility leases as operating leases, which may include escalation clauses that are based on an index or market rate. The Company accounts for l

Statement of Financial Position [Abstract]
Consolidated Sponsored Investment Products	5 . Consolidated Sponsored Investment Products In the normal course of business, the Company is the manager of various types of sponsored investment products, which may be considered VIE or VREs. The Company consolidates certain sponsored investment funds accounted for as VREs because it is deemed to control such funds. In addition, the Company may from time to time own equity or debt securities or enter into derivatives or loan arrangements with the vehicles, each of which are considered variable interests. The Company’s involvement in financing the operations of the VIEs is generally limited to its economic interest in the entity. The Company’s consolidated VIEs include certain sponsored investment products in which BlackRock has an economic interest and as the investment manager, is deemed to have both the power to direct the most significant activities of the products and the right to receive benefits (or the obligation to absorb losses) that could potentially be significant to these sponsored investment products. The assets of these VIEs are not available to creditors of the Company. In addition, the investors in these VIEs have no recourse to the credit of the Company. The following table presents the balances related to these CIPs accounted for as VIEs and VREs that were recorded on the consolidated statements of financial condition, including BlackRock’s net interest in these products: December 31, 2023 December 31, 2022 (in millions) VIEs VREs Total VIEs VREs Total Cash and cash equivalents (1) $ 234 $ 54 $ 288 $ 234 $ 31 $ 265 Investments: Trading debt securities 1,423 406 1,829 949 330 1,279 Equity securities at FVTNI 1,059 370 1,429 821 268 1,089 Loans 195 10 205 234 120 354 Other investments 427 171 598 373 77 450 Carried interest 1,916 — 1,916 1,497 — 1,497 Total investments 5,020 957 5,977 3,874 795 4,669 Other assets 83 39 122 68 29 97 Other liabilities (2) ( 2,233 ) ( 108 ) ( 2,341 ) ( 1,876 ) ( 48 ) ( 1,924 ) Noncontrolling interest - CIPs ( 1,625 ) ( 226 ) ( 1,851 ) ( 857 ) ( 125 ) ( 982 ) BlackRock's net interest in CIPs $ 1,479 $ 716 $ 2,195 $ 1,443 $ 682 $ 2,125 (1) The Company generally cannot readily access cash and cash equivalents held by CIPs to use in its operating activities. (2) At December 31, 2023 and 2022 , other liabilities of VIEs primarily include deferred carried interest liabilities and borrowings of a consolidated CLO. BlackRock’s total exposure to CIPs represents the value of its economic interest in these CIPs. Valuation changes associated with financial instruments held at fair value by these CIPs are reflected in nonoperating income (expense) and partially offset in net income (loss) attributable to NCI for the portion not attributable to BlackRock. Net gain (loss) related to consolidated VIEs is presented in the following table: (in millions) 2023 2022 2021 Nonoperating net gain (loss) on consolidated VIEs $ 310 $ ( 311 ) $ 296 Net income (loss) attributable to NCI on consolidated VIEs $ 174 $ ( 161 ) $ 289

In accordance with GAAP, certain equity method investees do not account for both their financial assets and liabilities under fair value measures; therefore, the Company’s investment in such equity method investees may not represent fair value. (3) Level 1 amount includes a minority investment in a publicly traded company. Level 3 amount includes a strategic private debt investment with changes in fair value recorded in AOCI, net of tax.

Level 3 amount primarily includes borrowings of a consolidated CLO classified based on the significance of unobservable inputs used for calculating the fair value of consolidated CLO assets, and a contingent liability related to an acquisition. Level 3 Assets. Level 3 assets predominantly include investments in CLOs, loans of consolidated CIPs, and a strategic private debt investment. Investments in CLOs and loans were valued based on single-broker nonbinding quotes or quotes from pricing services which use significant unobservable inputs. BlackRock's strategic private debt investment was valued using the income approach by discounting the expected cash flows to a single present value. For investments utilizing a discounted cashflow valuation technique, an increase (decrease) in the discount rate or risk premium in isolation could have resulted in a significantly lower (higher) fair value measurement as of December 31, 2023. Level 3 Liabilities . Level 3 liabilities primarily include borrowings of a consolidated CLO, which were valued based on the fair value of the assets of the consolidated CLO less the fair value of the Company’s economic interest in the CLO, as well as contingent liabilities related to certain acquisitions, which were valued based upon discounted cash flow analyses, using unobservable market data inputs, or other valuation techniques.

Realized and Unrealized Gains (Losses) for Level 3 Assets and Liabilities. Realized and unrealized gains (losses) recorded for Level 3 assets and liabilities are primarily reported in nonoperating income (expense) on the consolidated statements of income. A portion of net income (loss) related to securities held by CIPs is allocated to NCI to reflect net income (loss) not attributable to the Company. Transfers in and/or out of Levels. Transfers in and/or out of levels are reflected when significant inputs, including market inputs or performance attributes, used for the fair value measurement become observable/unobservable. Disclosures of Fair Value for Financial Instruments Not Held at Fair Value . At December 31, 2023 and 2022, the fair value of the Company’s financial instruments not held at fair value are categorized in the table below.

(2) Cash and cash equivalents are carried at either cost or amortized cost, which approximates fair value due to their short-term maturities. (3) At December 31, 2023 and 2022 , approximately $ 3.4 billion and $ 2.2 billion, respectively, of money market funds were recorded within cash and cash equivalents on the consolidated statements of financial condition. Money market funds are valued based on quoted market prices, or $ 1.00 per share, which generally is the NAV of the fund. (4) At December 31, 2023 and 2022, other assets included cash collateral of approximately $ 63 million and $ 69 million, respectively. See Note 8, Derivatives and Hedging for further information on derivatives held by the Company. In addition, other assets included $ 17 million of restricted cash at both December 31, 2023 and 2022. (5) Long-term borrowings are recorded at amortized cost, net of debt issuance costs. The fair value of the long-term borrowings, including the current portion of long-term borrowings, is determined using market prices and the EUR/USD foreign exchange rate at the end of December 2023 and 2022, respectively. See Note 14, Borrowings , for the fair value of each of the Company’s long-term borrowings. Investments in Certain Entities that Calculate NAV Per Share As a practical expedient to value certain investments that do not have a readily determinable fair value and have attributes of an investment company, the Company uses NAV as the fair value. The following tables list information regarding all investments that use a fair value measurement to account for both their financial assets and financial liabilities in their calculation of a NAV per share (or equivalent).

Borrowings	14 . Borrowings Short-Term Borrowings 2023 Revolving Credit Facility. The Company maintains an unsecured revolving credit facility which is available for working capital and general corporate purposes (the “2023 credit facility”). In March 2023, the 2023 credit facility was amended to, among other things, (1) increase the aggregate commitment amount by $ 300 million to $ 5 billion, (2) extend the maturity date to March 2028 and (3) change the secured overnight financing rate (“SOFR”) adjustment to 10 bps per annum for all SOFR-based borrowings. The 2023 credit facility permits the Company to request up to an additional $ 1.0 billion of borrowing capacity, subject to lender credit approval, which could increase the overall size of the 2023 credit facility to an aggregate principal amount of up to $ 6 billion. The 2023 credit facility requires the Company not to exceed a maximum leverage ratio (ratio of net debt to earnings before interest, taxes, depreciation and amortization, where net debt equals total debt less unrestricted cash) of 3 to 1 , which was satisfied with a ratio of less than 1 to 1 at December 31, 2023. At December 31, 2023 , the Company had no amount outstanding under the 2023 credit facility. Commercial Paper Program.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	15 . Commitments and Contingencies Investment Commitments . At December 31, 2023 , the Company had $ 738 million of various capital commitments to fund sponsored investment products, including CIPs. These products include private equity funds, real assets funds and opportunistic funds. This amount excludes additional commitments made by consolidated funds of funds to underlying third-party funds as third-party noncontrolling interest holders have the legal obligation to fund the respective commitments of such funds of funds. Generally, the timing of the funding of these commitments is unknown and the commitments are callable on demand at any time prior to the expiration of the commitment. These unfunded commitments are not recorded on the consolidated statements of financial condition. These commitments do not include potential future commitments approved by the Company that are not yet legally binding. The Company intends to make additional capital commitments from time to time to fund additional investment products for, and with, its clients. Contingencies Legal Proceedings. From time to time, BlackRock receives subpoenas or other requests for information from various US federal and state governmental and regulatory authorities and international governmental and regulatory authorities in connection with industry-wide or other investigations or proceedings. It is BlackRock’s policy to cooperate fully with such matters. BlackRock has been responding to requests from the SEC in connection with a publicly reported, industry-wide investigation of investment advisers’ compliance with record retention requirements relating to certain types of electronic communications. BlackRock is cooperating with the SEC’s investigation. The Company, certain of its subsidiaries and employees have been named as defendants in various legal actions, including arbitrations and other litigation arising in connection with BlackRock’s activities. Additionally, BlackRock-advised investment portfolios may be subject to lawsuits, any of which potentially could harm the investment returns of the applicable portfolio or result in the Company being liable to the portfolios for any resulting damages. Management, after consultation with legal counsel, currently does not anticipate that the aggregate liability arising out of regulatory matters or lawsuits will have a material effect on BlackRock’s results of operations, financial position, or cash flows. However, there is no assurance as to whether any such pending or threatened matters will have a material effect on BlackRock’s results of operations, financial position or cash flows in any future reporting period. Due to uncertainties surrounding the outcome of these matters, management cannot reasonably estimate the possible loss or range of loss that may arise from these matters. Indemnifications. In the ordinary course of business or in connection with certain acquisition agreements, BlackRock enters into contracts pursuant to which it may agree to indemnify third parties in certain circumstances. The terms of these indemnities vary from contract to contract and the amount of indemnification liability, if any, cannot be determined or the likelihood of any liability is considered remote. Consequently, no liability has been recorded on the consolidated statements of financial condition. In connection with securities lending transactions, BlackRock has agreed to indemnify certain securities lending clients against potential loss resulting from a borrower’s failure to fulfill its obligations under the securities lending agreement should the value of the collateral pledged by the borrower at the time of default be insufficient to cover the borrower’s obligation under the securities lending agreement. The amount of securities on loan as of December 31, 2023 and subject to this type of indemnification was approximately $ 259 billion. In the Company’s capacity as lending agent, cash and securities totaling approximately $ 276 billion were held as collateral for indemnified securities on loan at December 31, 2023. The fair value of these indemnifications was not material at December 31, 2023 .

Performance-Based Stock Options In 2017, pursuant to the Award Plan, the Company awarded performance-based stock option grants to certain employees ("2017 Performance-based Options"). Vesting of 2017 Performance-based Options was contingent upon the achievement of obtaining 125 % of BlackRock's grant-date stock price within five year s from the grant date and the attainment of Company performance measures during the four-year performance period. Both hurdles have been achieved, and the first two tranches of the awards vested at the end of 2022 and 2023 , respectively, with the final equal installment vesting at the end of 2024 . Vested options are exercisable for up to nine years following the grant date. The awards are generally forfeited if the employee leaves the Company before the respective vesting date.

(2) The expected stock volatility was based upon an average of historical stock price fluctuations of BlackRock’s common stock and an implied volatility at the grant date. (3) The expected dividend yield was calculated as the most recent quarterly dividend divided by the average three-month stock price as of the grant date. (4) The risk-free interest rate is based on the US Treasury Constant Maturities yield curve at grant date. On May 30, 2023, pursuant to the Award Plan, the Company awarded performance-based options to purchase 814,482 shares of BlackRock common stock to certain employees as long-term incentive compensation ("2023 Performance-based Options"). Vesting of 2023 Performance-based Options is contingent upon the achievement of obtaining 130 % of grant-date stock price over 60 calendar days within four years from the grant date and attainment of Company performance measures during the three-year performance period. If both hurdles are achieved, the award will vest in three tranches of 25 %, 25 % and 50 % in May of 2027 , 2028 and 2029 , respectively. Vested options are exercisable for up to nine years following the grant date, and the awards are forfeited if the employee resigns before the respective vesting date. The expense for each tranche is amortized over the respective requisite service period. The 2023 Performance-based Options have a strike price of $ 673.58 which was the closing price of the shares on the grant date. The grant-date fair value of the 2023 Performance-based Options was $ 120 million and was estimated using a Monte Carlo simulation with an embedded lattice model using the assumptions included in the following table: Grant Year Expected Term (Years) (1) Expected Stock Volatility (2) Expected Dividend Yield (3) Risk-Free Interest Rate (4) 2023 6.02 27.73 % 3.02 % 3.61 % (1) The expected term was derived using a Monte Carlo simulation with the embedded lattice model and represents the period of time that options granted are expected to be outstanding. (2) The expected stock volatility was based upon an average of historical stock price fluctuations of BlackRock’s common stock and an implied volatility at the grant date. (3) The expected dividend yield was calculated as the most recent quarterly dividend divided by the average three-month stock price as of the grant date. (4) The risk-free interest rate is based on the US Treasury Constant Maturities yield curve at grant date. Time-Based Stock Options On May 30, 2023, pursuant to the Award Plan, the Company awarded time-based stock options to purchase 326,391 shares of BlackRock common stock to certain employees as long-term incentive compensation ("2023 Time-based Options"). These awards will vest in three tranches of 25 %, 25 % and 50 % in May 2027 , 2028 and 2029 , respectively. Vested options can be exercised up to nine years following the grant date, and the awards are forfeited if the employee resigns before the respective vesting date. The 2023 Time-based Options have a strike price of $ 673.58 which was the closing price of the shares on the grant date. The grant-date fair value of the 2023 Time-based Options was $ 55 million and was estimated using a Black-Scholes-Merton model using the assumptions included in the following table: Grant Year Expected Term (Years) (1) Expected Stock Volatility (2) Expected Dividend Yield (3) Risk-Free Interest Rate (4) 2023 7.13 28.29 % 3.02 % 3.65 % (1) The expected term represents the period of time that options granted are expected to be outstanding, and was calculated as the midpoint between the weighted average time to vest and expiration. (2) The expected stock volatility was based upon an average of historical stock price fluctuations of BlackRock’s common stock and an implied volatility at the grant date. (3) The expected dividend yield was calculated as the most recent quarterly dividend divided by the average three-month stock price as of the grant date. (4) The risk-free interest rate is based on the US Treasury Constant Maturities yield curve at grant date. Employee Stock Purchase Plan (“ESPP”). The ESPP allows eligible employees to purchase the Company’s common stock at 95 % of the fair market value on the last day of each three-month offering period; therefore, the Company does not record compensation expense related to employees purchasing shares under the ESPP.

Investment Professional Deferred Compensation Program (“IPDCP”). The Company adopted IPDCP for the purpose of providing deferred compensation and retention incentives to certain employees. For this plan, the final value of the deferred amount to be distributed in cash upon vesting is associated with investment returns of certain investment funds. In January 2023, 2022 and 2021 , the Company granted approximately $ 90 million, $ 257 million, and $ 321 million of deferred compensation that will fluctuate with investment returns and will vest ratably over three years from the date of grant. The liabilities for this plan were $ 313 million and $ 358 million at December 31, 2023 and 2022, respectively, and are reflected in the consolidated statements of financial condition as accrued compensation and benefits. In January 2024 , the Company granted approximately $ 114 million of additional deferred compensation that will fluctuate with investment returns and will vest ratably over three years from the date of grant. Voluntary Deferred Compensation Plan. The Company adopted a Voluntary Deferred Compensation Plan (“VDCP”) that allows eligible employees in the US to elect to defer between 1 % and 100 % of their annual cash incentive compensation. The participants must specify a deferral period of up to 10 years from the year of deferral and additionally elect to receive distributions in the form of a lump sum or in up to 10 annual installments. VDCP deferred cash compensation expense includes the mark-to-market impact of investment returns. The liability balance of $ 144 million and $ 108 million at December 31, 2023 and 2022, respectively, is reflected on the consolidated statements of financial condition as accrued compensation and benefits.

Cash payments, if any, with respect to these percentage points will be made over time following the recipient’s termination of employment due to qualified retirement, death or disability, subject to his or her execution of a release of claims and continued compliance with his or her restrictive covenant obligations following termination. There was no material impact to the consolidated financial statements. Defined Contribution Plans The Company has several defined contribution plans primarily in the US and UK. Certain of the Company’s US employees participate in a defined contribution plan. Employee contributions of up to 8 % of eligible compensation, as defined by the plan and subject to Internal Revenue Code limitations, are matched by the Company at 50 % up to a maximum of $ 5,000 annually. In addition, the Company makes an annual retirement contribution to eligible participants equal to 3 - 5 % of eligible compensation. The Company’s contribution expense related to this plan was $ 86 million in 2023 , $ 83 million in 2022 , and $ 101 million in 2021. Certain UK wholly owned subsidiaries of the Company contribute to defined contribution plans for their employees.

BlackRock is subject to US federal income tax, state and local income tax, and foreign income tax in multiple jurisdictions. Tax years after 2015 remain open to US federal income tax examination. During 2014 and 2019, the Internal Revenue Service commenced its examination of BlackRock’s 2012 through 2015 tax years, for which the examination was concluded in 2023. During 2020 and 2021, the Internal Revenue Service commenced its examination of BlackRock’s 2017 through 2018 tax years and 2019 tax year, respectively. During 2023, the Internal Revenue Service commenced its examination of BlackRock’s 2016 tax year. The Company is currently under audit in several state and local jurisdictions. The significant state and local income tax examinations are in New York State for tax years 2012 through 2020, for which 2012 through 2014 examination was concluded during 2023, and New York City for tax years 2012 through 2014. No open state and local tax examinations cover years earlier than 2012. Upon conclusion of its examination, Her Majesty’s Revenue and Customs (“HMRC”) issued a closure notice during 2017 for various UK BlackRock subsidiaries for tax years 2009 and years after. At that time, the Company decided to pursue litigation for the tax matters included on such notice. During 2020, the Company received a favorable decision from the First Tier Tribunal (“FTT”), however, HMRC appealed to the Upper Tribunal (“UT”) and the UT ruled in HMRC’s favor, overturning the FTT’s decision in July 2022. BlackRock appealed UT’s decision to the UK Court of Appeal (“CoA”) and the appeal hearing is scheduled for March 2024. BlackRock does not expect the ultimate resolution to result in a material impact to the consolidated financial statements. From time to time, BlackRock may receive or be subject to tax authorities’ assessments and challenges related to income taxes. BlackRock does not currently expect the ultimate resolution of any other existing matters to be material to the consolidated financial statements. At December 31, 2023 , it is reasonably possible the total amounts of unrecognized tax benefits will change within the next twelve months due to completion of tax authorities’ exams or the expiration of statues of limitations. Management estimates that the existing liability for uncertain tax positions could decrease by approximately $ 65 million to $ 280 million within the next twelve months.

Subsequent Events [Abstract]
Subsequent Events	27 . Subsequent Events In January 2024, BlackRock announced that it had entered into a definitive agreement to acquire 100 % of the business and assets of Global Infrastructure Management LLC (referred to herein as Global Infrastructure Partners (“GIP”)), a leading independent infrastructure fund manager, for $ 3 billion in cash and approximately 12 million shares of BlackRock common stock. Approximately 30 % of the total consideration, all in stock, will be deferred and will be issued subject to the satisfaction of certain post-closing events. The Company intends to fund the cash consideration through $ 3 billion of additional debt. The Company believes the combination of GIP with BlackRock’s complementary infrastructure offerings will create a broad global infrastructure franchise with differentiated origination and asset management capabilities. The GIP Transaction is expected to close in the third quarter of 2024 subject to customary regulatory approvals and other closing conditions. On January 12, 2024 , the Company announced that the Board of Directors approved BlackRock’s quarterly dividend of $ 5.10 per share to be paid on March 22, 2024 to stockholders of record at the close of business on March 7, 2024 . The Company conducted a review for additional subsequent events and determined that no subsequent events had occurred that would require accrual or additional disclosures.

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2023
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and include the accounts of the Company and its controlled subsidiaries. Noncontrolling interests (“NCI”) on the consolidated statements of financial condition represent the portion of consolidated sponsored investment products (“CIPs”) and a consolidated affiliate (collectively, “consolidated entities”) in which the Company does not have direct equity ownership. Intercompany balances and transactions have been eliminated upon consolidation. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting periods. Actual results could differ from those estimates. Certain prior period presentations and disclosures, while not required to be recast, may be reclassified to ensure comparability with current period classifications.
Accounting Developments	Accounting Developments Segment Reporting. In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Improvements to Reportable Segment Disclosures (“ASU 2023-07”), which requires incremental disclosures about reportable segments but does not change the definition of a segment or the guidance for determining reportable segments. The new guidance requires disclosure of significant segment expenses that are (1) regularly provided to (or easily computed from information regularly provided to) the chief operating decision maker ("CODM") and (2) included in the reported measure of segment profit or loss. The new standard also requires companies to disclose the title and position of the individual (or the name of the committee) identified as the CODM, allows companies to disclose multiple measures of segment profit or loss if those measures are used to assess performance and allocate resources, and is applicable to companies with a single reportable segment. The requirements are effective for annual reporting periods beginning on January 1, 2024, and are required to be applied retrospectively. Early adoption is permitted. The Company does not expect the additional disclosure requirements under ASU 2023-07 to have a material impact on the consolidated financial statements. Income Tax Disclosure Requirements. In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures (“ASU 2023-09”), which enhances interim and annual income tax disclosures. The two primary enhancements disaggregate existing income tax disclosures related to the effective tax rate reconciliation and income taxes paid. The additional disclosure requirements under ASU 2023-09 are required to be applied prospectively and are effective for the Company on January 1, 2025. The Company does not expect the additional disclosure requirements under ASU 2023-09 to have a material impact on the consolidated financial statements.
Cash and Cash Equivalents	Cash and Cash Equivalents . Cash and cash equivalents primarily consists of cash, money market funds and short-term, highly liquid investments with original maturities of three months or less. Cash and cash equivalent balances that are legally restricted from use by the Company are recorded in other assets on the consolidated statements of financial condition. Cash balances maintained by consolidated VIEs and voting rights entities (“VREs”) are not considered legally restricted and are included in cash and cash equivalents on the consolidated statements of financial condition.
Investments	Investments Investments in Debt Securities. The Company classifies debt investments as held-to-maturity or trading based on the Company’s intent and ability to hold the debt security to maturity or its intent to sell the security. Held-to-maturity securities are purchased with the positive intent and ability to be held to maturity and are recorded at amortized cost on the consolidated statements of financial condition. Trading securities are those investments that are purchased principally for the purpose of selling them in the near term. Trading securities are carried at fair value on the consolidated statements of financial condition with changes in the fair value recorded through net income (“FVTNI”) within nonoperating income (expense). Trading securities include certain investments in collateralized loan obligations (“CLOs”) for which the fair value option is elected in order to reduce operational complexity of bifurcating embedded derivatives. Investments in Equity Securities. Equity securities are generally carried at fair value on the consolidated statements of financial condition with changes in the FVTNI within nonoperating income (expense). For nonmarketable equity securities, the Company generally elects to apply the practicality exception to fair value measurement, under which such securities will be measured at cost, less impairment, plus or minus observable price changes for identical or similar securities of the same issuer with such changes recorded through net income within nonoperating income (expense). Dividends received are recorded as dividend income within nonoperating income (expense). Equity Method. The Company applies the equity method of accounting for equity investments where the Company does not consolidate the investee, but can exert significant influence over the financial and operating policies of the investee. The evaluation of whether the Company exerts control or significant influence over the financial and operational policies of its investees is based on the facts and circumstances surrounding each individual investment. Factors considered in these evaluations may include the type of investment, the legal structure of the investee, the terms of BlackRock's contractual agreements, including investor voting or other rights, any influence BlackRock may have on the governing board of the investee, the legal rights of other investors in the entity pursuant to the entity’s operating documents and the relationship between BlackRock and other investors in the entity. The Company’s share of the investee’s underlying net income or loss is recorded as net gain (loss) on investments within nonoperating income (expense) and as other revenue for certain strategic minority investments since such investees are considered to be an extension of the Company’s core business. The Company’s share of net income of the investee is recorded based upon the most current information available at the time, which may precede the date of the consolidated statement of financial condition. Distributions received reduce the Company’s carrying value of the investment and the cost basis if deemed to be a return of capital. The Company classifies distributions in the consolidated statements of cash flows as either distributions of earnings (operating) or distributions of capital (investing) based on the nature of the distribution. Impairments of Investments. Management periodically assesses equity method, nonmarketable investments, and held-to-maturity investments for impairment. If impairment exists, an impairment charge would be recorded for the excess of the carrying amount of the investment over its estimated fair value in the consolidated statements of income. For equity method investments and nonmarketable investments, impairment evaluation considers qualitative factors, including the financial conditions and specific events related to an investee, that may indicate the fair value of the investment is less than its carrying value. For held-to-maturity investments, impairment is evaluated using market values, where available, or the expected future cash flows of the investment. For the Company’s investments in CLOs, the Company reviews cash flow estimates over the life of each CLO investment. On a quarterly basis, if the present value of the estimated future cash flows is lower than the carrying value of the investment and there is an adverse change in estimated cash flows, an impairment is considered to be other-than-temporary.
Consolidation	Consolidation. The Company performs an analysis for investment products to determine if the product is a VIE or a VRE. Factors considered in this analysis include the entity’s legal organization, the entity’s capital structure, the rights of equity investment holders and the Company’s contractual involvement with, and economic interest in, the entity and any related party or de facto agent implications of the Company’s involvement with the entity. Entities that are determined to be VIEs are consolidated if the Company is the primary beneficiary (“PB”) of the entity. VREs are typically consolidated if the Company holds the majority voting interest. Upon the occurrence of certain events (such as contributions and redemptions, either by the Company, or third parties, or amendments to an entity’s governing documents), management reviews and reconsiders its previous conclusion regarding the status of an entity as a VIE or a VRE. Consolidation of Variable Interest Entities . Certain investment products for which a controlling financial interest is achieved through arrangements that do not involve or are not directly linked to voting interests are deemed consolidated VIEs. BlackRock reviews factors, including whether or not (1) the entity has equity at risk that is sufficient to permit the entity to finance its activities without additional subordinated support from other parties and (2) the equity holders at risk have the obligation to absorb losses, the right to receive residual returns, and the right to direct the activities of the entity that most significantly impact the entity’s economic performance, to determine if the investment product is a VIE. The PB of a VIE is defined as the variable interest holder that has a controlling financial interest in the VIE. A controlling financial interest is defined as (1) the power to direct the activities of the VIE that most significantly impact its economic performance and (2) the obligation to absorb losses of the entity or the right to receive benefits from the entity that potentially could be significant to the VIE. The Company generally consolidates VIEs in which it holds an economic interest of 10 % or greater and deconsolidates such VIEs once economic interest falls below 10 %. Management continually reconsiders whether the Company is deemed to be a VIE’s PB. Consolidation of Voting Rights Entities . BlackRock is required to consolidate an investee to the extent that BlackRock can exert absolute control over the financial and operating policies of the investee, which generally exists if there is a greater than 50% voting equity interest. Retention of Specialized Investment Company Accounting Principles. Upon consolidation of sponsored investment products, the Company retains the specialized investment company accounting principles of the underlying funds. All of the underlying investments held by such CIPs are carried at fair value with corresponding changes in the investments’ fair values reflected in net income within nonoperating income (expense). When the Company no longer controls these funds due to reduced ownership percentage or other reasons, the funds are deconsolidated and accounted for as an equity method investment or equity securities FVTNI. Consolidated Affiliate. The Company owns 50.1 % of an asset management company in China - BlackRock CCB Wealth Management Company Ltd. (“WMC”). The Company consolidates WMC, which it deems to be a VRE, because it exerts control over the financial and operating policies of the entity, based on the Company’s 50.1 % ownership and voting rights.
Separate Account Assets and Liabilities	Separate Account Assets and Liabilities . Separate account assets are maintained by BlackRock Life Limited, a wholly owned subsidiary of the Company, which is a registered life insurance company in the United Kingdom ("UK"), and represent segregated assets held for purposes of funding individual and group pension contracts. The life insurance company does not underwrite any insurance contracts that involve any insurance risk transfer from the insured to the life insurance company. The separate account assets primarily include equity securities, debt securities, money market funds and derivatives. The separate account assets are not subject to general claims of the creditors of BlackRock. These separate account assets and the related equal and offsetting liabilities are recorded as separate account assets and separate account liabilities on the consolidated statements of financial condition. The net investment income attributable to separate account assets supporting individual and group pension contracts accrues directly to the contract owner and is not reported on the consolidated statements of income. While BlackRock has no economic interest in these separate account assets and liabilities, BlackRock earns policy administration and management fees associated with these products, which are included in investment advisory, administration fees and securities lending revenue on the consolidated statements of income.
Separate Account Collateral Assets Held and Liabilities Under Securities Lending Agreements	Separate Account Collateral Assets Held and Liabilities Under Securities Lending Agreements. The Company facilitates securities lending arrangements whereby securities held by separate accounts maintained by BlackRock Life Limited are lent to third parties under global master securities lending agreements. In exchange, the Company receives collateral by obtaining either (1) legal title or (2) first ranking priority security interest. The minimum collateral values generally range from approximately 102 % to 112 % of the value of the securities lent in order to reduce counterparty risk. The required collateral value is calculated on a daily basis. The global master securities lending agreements provide the Company the right to request additional collateral or, in the event of borrower default, the right to liquidate collateral. The securities lending transactions entered into by the Company are accompanied by an agreement that entitles the Company to request the borrower to return the securities at any time; therefore, these transactions are not reported as sales. In situations where the Company receives the legal title to collateral under these securities lending arrangements, the Company records an asset on the consolidated statements of financial condition and an equal collateral liability for the obligation to return the collateral. Additionally, in situations where the Company obtains a first ranking priority security interest in the collateral, the Company does not have the ability to pledge or resell the collateral and therefore does not record the collateral on the consolidated statements of financial condition. At December 31, 2023 and 2022 , the fair value of loaned securities held by separate accounts was approximately $ 9.3 billion and $ 10.2 billion, respectively, and the fair value of the collateral under these securities lending agreements was approximately $ 10.1 billion and $ 11.0 billion, respectively, of which approximately $ 4.6 billion as of 2023 and $ 5.8 billion as of 2022 was recognized on the consolidated statements of financial condition. During 2023 and 2022 , the Company had no t resold or repledged any of the collateral received under these arrangements. The securities lending revenue earned from lending securities held by the separate accounts is included in investment advisory, administration fees and securities lending revenue on the consolidated statements of income.
Property and Equipment	Property and Equipment . Property and equipment are recorded at cost less accumulated depreciation. Depreciation is generally determined by cost less any estimated residual value using the straight-line method over the estimated useful lives of the various classes of property and equipment. Leasehold improvements are amortized using the straight-line method over the shorter of the estimated useful life or the remaining lease term. The Company capitalizes certain costs incurred in connection with developing or obtaining software within property and equipment. Capitalized software costs are amortized, beginning when the software product is ready for its intended use, over the estimated useful life of the software of approximately three years .
Goodwill and Intangible Assets	Goodwill and Intangible Assets . Goodwill represents the cost of a business acquisition in excess of the fair value of the net assets acquired. The Company has determined that it has one reporting unit for goodwill impairment testing purposes, the consolidated BlackRock single operating segment, which is consistent with internal management reporting and management's oversight of operations. The Company performs an impairment assessment of its goodwill at least annually, as of July 31st. In its assessment of goodwill for impairment, the Company considers such factors as the book value and market capitalization of the Company. Intangible assets are comprised of indefinite-lived intangible assets and finite-lived intangible assets acquired in a business acquisition. The value of contracts to manage assets in proprietary open-end funds and collective trust funds and certain other commingled products without a specified termination date is generally classified as indefinite-lived intangible assets. In addition, trade names/trademarks are considered indefinite-lived intangible assets when they are expected to generate cash flows indefinitely. Indefinite-lived intangible assets and goodwill are not amortized. Finite-lived investor/customer relationships, technology-related assets, and management contracts, which relate to acquired separate accounts and funds, that are expected to contribute to the future cash flows of the Company for a specified period of time, are amortized over their estimated useful lives. On a quarterly basis, the Company considers whether the indefinite-lived and finite-lived classifications are still appropriate. The Company performs assessments to determine if any intangible assets are potentially impaired at least annually, as of July 31st. The carrying value of finite-lived assets and their remaining useful lives are reviewed to determine if circumstances exist which may indicate a potential impairment or revisions to the amortization period. In evaluating whether it is more likely than not that the fair value of indefinite-lived intangibles is less than its carrying value, BlackRock assesses various significant quantitative factors, including assets under management (“AUM”), revenue basis points, projected AUM growth rates, operating margins, tax rates and discount rates. If an indefinite-lived intangible is determined to be more likely than not impaired, then the fair value of the asset is compared with its carrying value and any excess of the carrying value over the fair value would be recognized as an expense in the period in which the impairment occurs. For finite-lived intangible assets, if potential impairment circumstances are considered to exist, the Company will perform a recoverability test using an undiscounted cash flow analysis. If the carrying value of the asset is determined not to be recoverable based on the undiscounted cash flow test, the difference between the carrying value of the asset and its current fair value would be recognized as an expense in the period in which the impairment occurs.
Noncontrolling Interests	Noncontrolling Interests. NCI consist of third-party investments in the Company’s CIPs (“NCI – CIPs”) and the WMC. The Company reports NCI in stockholders’ equity, separate from the parent’s equity, on the consolidated statements of financial condition. NCI that are redeemable at the option of the holders are classified as temporary equity at estimated redemption value and nonredeemable NCI are classified as a component of permanent equity in the consolidated statements of financial condition. In addition, the Company reports net income (loss) attributable to redeemable and nonredeemable NCI holders in net income (loss) attributable to NCI in the consolidated statements of income.
Treasury Stock	Treasury Stock . The Company records common stock purchased for treasury at cost. At the date of subsequent reissuance, the treasury stock account is reduced by the cost of such stock using the average cost method.
Revenue Recognition	Revenue Recognition. Revenue is recognized upon transfer of control of promised services to customers in an amount to which the Company expects to be entitled in exchange for those services. The Company enters into contracts that can include multiple services, which are accounted for separately if they are determined to be distinct. Consideration for the Company’s services is generally in the form of variable consideration because the amount of fees is subject to market conditions that are outside of the Company’s influence. The Company includes variable consideration in revenue when it is no longer probable of significant reversal, i.e. when the associated uncertainty is resolved. For some contracts with customers, the Company has discretion to involve a third party in providing services to the customer. Generally, the Company is deemed to be the principal in these arrangements because the Company controls the promised services before they are transferred to customers, and accordingly presents the revenue gross of related costs. Investment Advisory, Administration Fees and Securities Lending Revenue. Investment advisory and administration fees are recognized as the services are performed over time because the customer is receiving and consuming the benefits as they are provided by the Company. Fees are primarily based on agreed-upon percentages of AUM and recognized for services provided during the period, which are distinct from services provided in other periods. Such fees are affected by changes in AUM, including market appreciation or depreciation, foreign exchange translation and net inflows or outflows. Investment advisory and administration fees for investment funds are shown net of fee waivers. In addition, the Company may contract with third parties to provide sub-advisory services on its behalf. The Company presents the investment advisory fees and associated costs to such third-party advisors on a gross basis where it is deemed to be the principal and on a net basis where it is deemed to be the agent. Management judgment involved in making these assessments is focused on ascertaining whether the Company is primarily responsible for fulfilling the promised service. The Company also earns revenue by lending securities on behalf of clients, primarily to highly rated banks and broker-dealers. The securities loaned are collateralized by either cash or securities, generally ranging from 102 % to 112 % of the value of the loaned securities. Securities lending fees are based on (1) a percentage of the notional value of the loaned securities and (2) a spread between the interest earned on the reinvested cash collateral and the amount rebated to the borrower. Revenue is recognized over time as services are performed. Generally, the securities lending fees are shared between the Company and the funds or other third-party accounts managed by the Company from which the securities are borrowed. For 2023, 2022 and 2021 , securities lending revenue earned by the Company totaled $ 675 million, $ 599 million and $ 555 million, respectively, and is recorded in investment advisory, administration and securities lending revenue on the consolidated statements of income. Investment advisory, administration fees and securities lending revenue are reported together as the fees for these services often are agreed upon with clients as a bundled fee. Money Market Fee Waivers. The Company may voluntarily waive a portion of its management fees on certain money market funds to ensure that they maintain a targeted level of daily net investment income (the “Yield Support waivers”). There were no Yield Support waivers during 2023. During 2022 and 2021 , these waivers resulted in a reduction of management fees of approximately $ 72 million, and $ 500 million respectively, which was partially offset by a reduction of BlackRock’s distribution and servicing costs paid to financial intermediaries. The Company may increase or decrease the level of Yield Support waivers in future periods. Investment Advisory Performance Fees / Carried Interest. The Company receives investment advisory performance fees, including incentive allocations (carried interest) from certain actively managed investment funds and certain separately managed accounts. These performance fees are dependent upon exceeding specified relative or absolute investment return thresholds, which vary by product or account, and include monthly, quarterly, annual or longer measurement periods. Performance fees, including carried interest, are generated on certain management contracts when performance hurdles are achieved. Such performance fees are recognized when the contractual performance criteria have been met and when it is determined that they are no longer probable of significant reversal. Given the unique nature of each fee arrangement, contracts with customers are evaluated on an individual basis to determine the timing of revenue recognition. Significant judgment is involved in making such determination. Performance fees typically arise from investment management services that began in prior reporting periods. Consequently, a portion of the fees the Company recognizes may be partially related to the services performed in prior periods that meet the recognition criteria in the current period. At each reporting date, the Company considers various factors in estimating performance fees to be recognized, including carried interest. The Company is allocated carried interest from certain alternative investment products upon exceeding performance thresholds. The Company may be required to reverse/return all, or part, of such carried interest allocations/distributions depending upon future performance of these funds. Carried interest subject to such clawback provisions is recorded in investments or cash and cash equivalents to the extent that it is distributed, on its consolidated statements of financial condition. The Company records a liability for deferred carried interest to the extent it receives cash or capital allocations related to carried interest prior to meeting the revenue recognition criteria. A portion of the deferred carried interest may also be paid to certain employees. The ultimate timing of the recognition of performance fee revenue and related compensation expense, if any, is unknown. Technology services revenue. The Company offers investment management technology systems, risk management services, wealth management and digital distribution tools, all on a fee basis. Clients include banks, insurance companies, official institutions, pension funds, asset managers, retail distributors and other investors. Fees earned for technology services are primarily recorded as services are performed over time and are generally determined using the value of positions on the Aladdin platform, or on a fixed-rate basis. Revenue derived from the sale of software licenses is recognized upon the granting of access rights. Distribution Fees. The Company earns distribution and service fees related to distributing investment products and shareholder support services for investment portfolios. Distribution fees are passed-through to third-party distributors, which perform various fund distribution services and shareholder servicing of certain funds on the Company’s behalf, and are recognized as distribution and servicing costs. The Company presents distribution fees and related distribution and servicing costs incurred on a gross basis. Distribution fees primarily consist of ongoing distribution fees, shareholder servicing fees and upfront sales commissions for serving as the principal underwriter and/or distributor for certain managed mutual funds. The service of distribution is satisfied at the point in time when an investor makes an investment in a share class of the managed mutual funds. Fees are generally considered variable consideration because they are based on the value of AUM and are uncertain on trade date. Accordingly, the Company recognizes distribution fees when the amounts become known and the portion recognized in the current period may relate to distribution services performed in prior periods. Upfront sales commissions are recognized on a trade date basis. Shareholder servicing fees are based on AUM and recognized in revenue as the services are performed. Advisory and other revenue. Advisory and other revenue primarily includes fees earned for advisory services, fees earned for transition management services primarily comprised of commissions recognized in connection with buying and selling securities on behalf of customers, and equity method investment earnings related to certain strategic minority investments. Advisory services fees are determined using fixed-rate fees and are recognized over time as the related services are completed. Commissions related to transition management services are recorded on a trade-date basis as transactions occur.
Stock-based Compensation	Stock-based Compensation . The Company recognizes compensation cost for equity classified awards based on the grant-date fair value of the award. The compensation cost is recognized over the period during which an employee is required to provide service (usually the vesting period) in exchange for the stock-based award. The Company measures the grant-date fair value of restricted stock units (“RSUs”) using the Company’s stock price on the date of grant. Stock-based awards may have performance, market and/or service conditions. For employee stock options and awards with market conditions, the Company uses pricing models. Compensation cost for awards containing performance conditions is recognized if it is probable that the conditions will be achieved. The probability of achievement is assessed on a quarterly basis. If a stock-based award is modified after the grant-date, incremental compensation cost is recognized for an amount equal to the excess of the fair value of the modified award over the fair value of the original award immediately before the modification. Awards under the Company’s stock-based compensation plans vest over various periods. Compensation cost is recorded by the Company on a straight-line basis over the requisite service period for each separate vesting portion of the award as if the award is, in-substance, multiple awards and is adjusted for actual forfeitures as they occur. The Company amortizes the grant-date fair value of stock-based compensation awards made to retirement-eligible employees over the requisite service period. Upon notification of retirement, the Company accelerates the unamortized portion of the award over the contractually required retirement notification period. The Company recognizes all excess tax benefits and deficiencies in income tax expense on the consolidated statements of income, which results in volatility of income tax expense as a result of fluctuations in the Company’s stock price. Accordingly, the Company recorded a discrete income tax benefit of $ 41 million, $ 87 million and $ 43 million during 2023, 2022 and 2021 , respectively, for vested RSUs where the grant date stock price was lower than the vesting date stock price.
Distribution and Servicing Costs	Distribution and Servicing Costs . Distribution and servicing costs include payments to third parties, primarily associated with distribution and servicing of client investments in certain BlackRock products. Distribution and servicing costs are expensed as incurred.
Direct Fund Expenses	Direct Fund Expense . Direct fund expense, which is expensed as incurred, primarily consists of third-party nonadvisory expense incurred by BlackRock related to certain investment products for the use of certain index trademarks, reference data for certain indices, custodial services, fund administration, fund accounting, transfer agent services, shareholder reporting services, audit and tax services as well as other fund-related expense directly attributable to the nonadvisory operations of the fund.
Leases	Leases . The Company determines if a contract is a lease or contains a lease at inception. The Company accounts for its office facility leases as operating leases, which may include escalation clauses that are based on an index or market rate. The Company accounts for lease and non-lease components, including common areas maintenance charges, as a single component for its leases. The Company elected the short-term lease exception for leases with an initial term of 12 months or less. Consequently, such leases are not recorded on the consolidated statements of financial condition. The Company’s lease terms include options to extend or terminate the lease when it is reasonably certain they will be exercised or not. The Company recognizes operating right-of-use (“ROU”) assets and operating lease liabilities on the consolidated statements of financial condition based on the present value of future lease payments over the lease term at the commencement date discounted using an incremental borrowing rate (“IBR”). The IBR for individual leases is estimated considering the Company’s or a subsidiary’s credit rating using various financial metrics, such as revenue, operating margin and revenue growth, and, as appropriate, performing market analysis of yields on publicly traded bonds (secured or unsecured) with similar terms of comparable companies in a similar economic environment. ROU assets are tested for impairment when there is an indication that the carrying value of an asset may not be recoverable. Fixed lease payments made over the lease term are recorded as lease expense on a straight-line basis. Variable lease payments based on usage, changes in an index or market rate are expensed as incurred.
Foreign Exchange	Foreign Exchange . Foreign currency transactions are recorded at the exchange rates prevailing on the dates of the transactions. Monetary assets and liabilities that are denominated in foreign currencies are subsequently remeasured into the functional currencies of the Company's subsidiaries at the rates prevailing at each statement of financial condition date. Gains and losses arising on remeasurement are included in general and administration expense on the consolidated statements of income. Revenue and expenses are translated at average exchange rates during the period. Gains or losses resulting from translating foreign currency financial statements into United States ("US") dollars are included in accumulated other comprehensive income (loss) (“AOCI”), a separate component of stockholders’ equity, on the consolidated statements of financial condition.
Income Taxes	Income Taxes . Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases using currently enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred income tax assets and liabilities is recognized on the consolidated statements of income in the period that includes the enactment date. Management periodically assesses the recoverability of its deferred income tax assets based upon expected future earnings, taxable income in prior carryback years, future deductibility of the asset, changes in applicable tax laws and other factors. If management determines that it is not more likely than not that the deferred tax asset will be fully recoverable in the future, a valuation allowance will be established for the difference between the asset balance and the amount expected to be recoverable in the future. This allowance will result in additional income tax expense. Further, the Company records its income taxes receivable and payable based upon its estimated income tax position.
Earnings per Share ("EPS")	Earnings per Share (“EPS”) . Basic EPS is calculated by dividing net income applicable to common shareholders by the weighted-average number of shares outstanding during the period. Diluted EPS includes the determinants of basic EPS and common stock equivalents outstanding during the period. Diluted EPS is computed using the treasury stock method.
Business Segments	Business Segments . The Company’s management directs BlackRock’s operations as one business, the asset management business. The Company utilizes a consolidated approach to assess performance and allocate resources. As such, the Company operates in one business segment.
Fair Value Measurements	Fair Value Measurements Hierarchy of Fair Value Inputs. The Company uses a fair value hierarchy that prioritizes inputs to valuation approaches used to measure fair value. The fair value hierarchy gives the highest priority to quoted prices (unadjusted) in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. Assets and liabilities measured and reported at fair value are classified and disclosed in one of the following categories: Level 1 Inputs: Quoted prices (unadjusted) in active markets for identical assets or liabilities at the reporting date. • Level 1 assets may include listed mutual funds, ETFs, listed equities, commodities and certain exchange-traded derivatives. Level 2 Inputs: Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities that are not active; quotes from pricing services or brokers for which the Company can determine that orderly transactions took place at the quoted price or that the inputs used to arrive at the price are observable; and inputs other than quoted prices that are observable, such as models or other valuation methodologies. • Level 2 assets may include debt securities, loans held within consolidated CLOs, short-term floating-rate notes, asset-backed securities, as well as over-the-counter derivatives, including interest rate swaps and foreign currency exchange contracts that have inputs to the valuations that generally can be corroborated by observable market data. Level 3 Inputs: Unobservable inputs for the valuation of the asset or liability, which may include nonbinding broker quotes. Level 3 assets include investments for which there is little, if any, market activity. These inputs require significant management judgment or estimation. • Level 3 assets may include direct private equity investments, including those held within CIPs, investments in CLOs and loans held within consolidated CLOs and CIPs. • Level 3 liabilities may include borrowings of consolidated CLOs and contingent liabilities related to acquisitions valued based upon discounted cash flow analyses using unobservable market data, or other valuation techniques. Significance of Inputs. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the financial instrument. Valuation Approaches. The fair values of certain Level 3 assets and liabilities were determined using various valuation approaches as appropriate, including third-party pricing vendors, broker quotes and market and income approaches. A significant number of inputs used to value equity, debt securities, and loans held within CLOs and CIPs are sourced from third-party pricing vendors. Generally, prices obtained from pricing vendors are categorized as Level 1 inputs for identical securities traded in active markets and as Level 2 for other similar securities if the vendor uses observable inputs in determining the price. In addition, quotes obtained from brokers generally are nonbinding and categorized as Level 3 inputs. However, if the Company is able to determine that market participants have transacted for the asset in an orderly manner near the quoted price or if the Company can determine that the inputs used by the broker are observable, the quote is classified as a Level 2 input. Investments Measured at Net Asset Values. As a practical expedient, the Company uses net asset value (“NAV”) as the fair value for certain investments. The inputs to value these investments may include the Company’s capital accounts for its partnership interests in various alternative investments, including hedge funds, real assets and private equity funds, which may be adjusted by using the returns of certain market indices. The various partnerships are investment companies, which record their underlying investments at fair value based on fair value policies established by management of the underlying fund. Fair value policies at the underlying fund generally require the fund to utilize pricing/valuation information from third-party sources, including independent appraisals. However, in some instances, current valuation information for illiquid securities or securities in markets that are not active may not be available from any third-party source or fund management may conclude that the valuations that are available from third-party sources are not reliable. In these instances, fund management may perform model-based analytical valuations that could be used as an input to value these investments. Fair Value Assets and Liabilities of Consolidated CLO. The Company applies the fair value option provisions for eligible assets, including loans, held by a consolidated CLO. As the fair value of the financial assets of the consolidated CLO is more observable than the fair value of the borrowings of the consolidated CLO, the Company measures the fair value of the borrowings of the consolidated CLO equal to the fair value of the assets of the consolidated CLO less the fair value of the Company’s economic interest in the CLO.
Derivatives and Hedging Activities	Derivatives and Hedging Activities . The Company does not use derivative financial instruments for trading or speculative purposes. The Company uses derivative financial instruments primarily for purposes of hedging exposures to fluctuations in foreign currency exchange rates of certain assets and liabilities, and market price and interest rate exposures with respect to its total portfolio of seed investments in sponsored investment products. Certain CIPs also utilize derivatives as a part of their investment strategy. In addition, during 2023, the Company acquired both investments and derivatives to economically hedge market valuation changes on certain deferred cash compensation plans, for which the final value of the deferred amount distributed to employees in cash upon vesting is determined based on the returns of specified investment funds. The Company recognizes compensation expense for the appreciation (depreciation) of the deferred cash compensation liability in proportion to the vested amount of the award during a respective period, while the gain (loss) to economically hedge these plans is immediately recognized in nonoperating income (expense). See Note 4, Investments , and Note 8, Derivatives and Hedging , for further information on the Company’s investments and derivatives, respectively, used to economically hedge these deferred cash compensation plans. The Company records all derivative financial instruments as either assets or liabilities at fair value on a gross basis in the consolidated statements of financial condition. Credit risks are managed through master netting and collateral support agreements. The amounts related to the right to reclaim or the obligation to return cash collateral may not be used to offset amounts due under the derivative instruments in the normal course of settlement. Therefore, such amounts are not offset against fair value amounts recognized for derivative instruments with the same counterparty and are included in other assets and other liabilities. Changes in the fair value of the Company’s derivative financial instruments are recognized in earnings and, where applicable, are offset by the corresponding gain or loss on the related foreign-denominated or hedged assets or liabilities, on the consolidated statements of income. The Company may also use financial instruments designated as net investment hedges for accounting purposes to hedge net investments in international subsidiaries whose functional currency is not US dollars. The gain or loss from revaluing net investment hedges at the spot rate is deferred and reported within AOCI on the consolidated statements of financial condition. The Company reassesses the effectiveness of its net investment hedge at least quarterly.
