Accounting Policies [Abstract]
Significant Accounting Policies	2. Significant Accounting Policies Basis of Presentation . These condensed 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 on the condensed consolidated statements of financial condition represents the portion of consolidated sponsored investment funds in which the Company does not have direct equity ownership. Accounts and transactions between consolidated entities have been eliminated. 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 financial information that normally is included in annual financial statements, including certain financial statement footnotes, is not required for interim reporting purposes and has been condensed or omitted herein. These condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and notes related thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015, which was filed with the Securities and Exchange Commission (“SEC”) on February 26, 2016 (“2015 Form 10-K”). The interim financial information at September 30, 2016 and for the three and nine months ended September 30, 2016 and 2015 is unaudited. However, in the opinion of management, the interim information includes all normal recurring adjustments necessary for the fair presentation of the Company’s results for the periods presented. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year. Certain items previously reported have been reclassified to conform to the current year presentation. Recent Accounting Pronouncements Adopted in the Nine Months Ended September 30, 2016 Accounting for Measurement-Period Adjustments . In September 2015, the Financial Accounting Standards Board (“FASB”) issued ASU 2015-16, (“ASU 2015-16”). Under ASU 2015-16, an acquirer must recognize, upon determination, adjustments to the original amounts recorded for a business acquisition that are identified during the one-year period following the acquisition date. Previously, prior period information was required to be restated. The Company adopted ASU 2015-16 prospectively on January 1, 2016 and will apply the ASU to any adjustments related to business acquisitions. Transition to Equity Method Accounting. In March 2016, the FASB issued ASU 2016-07, (“ASU 2016-07”). ASU 2016-07 eliminates the requirement to apply the equity method of accounting retrospectively to an investment that subsequently qualifies for such accounting as a result of obtaining significant influence. The Company adopted ASU 2016-07 prospectively on January 1, 2016. Fair Value Measurements. Hierarchy of Fair Value Inputs . The Company uses a fair value hierarchy that prioritizes inputs to valuation techniques 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 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, investments in collateralized loan obligations (“CLOs”), short-term floating-rate notes, asset-backed securities, securities held within consolidated hedge funds, restricted public securities valued at a discount, as well as over-the-counter derivatives, including interest and inflation 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 held within consolidated funds and investments in CLOs. • Level 3 liabilities include contingent liabilities related to acquisitions valued primarily based upon discounted cash flow analysis using unobservable market data. 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 Techniques. The fair values of certain Level 3 assets and liabilities were determined using various methodologies as appropriate, including third-party pricing vendors, broker quotes and market and income approaches. Such quotes and modeled prices are evaluated for reasonableness through various procedures, including due diligence reviews of third-party pricing vendors, variance analyses, consideration of the current market environment and other analytical procedures. A significant number of inputs used to value equity, debt securities and investments in CLOs is 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 or as Level 2 for other similar securities if the vendor uses observable inputs in determining the price. Annually, BlackRock’s internal valuation committee or other designated groups review both the valuation methodologies, including the general assumptions and methods used to value various asset classes, and operational processes with these vendors. On a quarterly basis, meetings are held with key vendors to identify any significant changes to the vendors’ processes. 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 NAV as the fair value for certain investments. The inputs to value these investments may include BlackRock 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 generally 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. Derivative Instruments 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 exposures for certain seed investments. However, certain consolidated sponsored investment funds may also invest in derivatives as a part of their investment strategy. 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 currency-denominated assets or liabilities or hedged investments, on the condensed 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 different from U.S. dollars. The gain or loss from revaluing accounting hedges of net investments in foreign operations at the spot rate is deferred and reported within accumulated other comprehensive income on the condensed consolidated statements of financial condition. The Company reassesses the effectiveness of its net investment hedge on a quarterly basis. Money Market Fee Waivers . The Company is currently voluntarily waiving a portion of its management fees on certain money market funds to ensure that they maintain a minimum level of daily net investment income (the “Yield Support waivers”). During the three and nine months ended September 30, 2016, these waivers resulted in a reduction of management fees of approximately $17 million and $42 million, respectively. During the three and nine months ended September 30, 2015, these waivers resulted in a reduction of management fees of approximately $32 million and $112 million, respectively. Approximately 45% of year-to-date Yield Support waivers for both nine months ended September 30, 2016, and 2015 were offset by a reduction of BlackRock’s distribution and servicing costs paid to a financial intermediary. BlackRock has provided Yield Support waivers in prior periods and may increase or decrease the level of fee waivers in future periods. 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, 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 condensed 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 condensed 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 condensed 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 legal title to the collateral with minimum values generally ranging 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. The Company records on the condensed consolidated statements of financial condition the cash and noncash collateral received under these BlackRock Life Limited securities lending arrangements as its own asset in addition to an equal and offsetting collateral liability for the obligation to return the collateral. 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 condensed consolidated statements of income. During the nine months ended September 30, 2016 and 2015, the Company had not resold or repledged any of the collateral received under these arrangements. At September 30, 2016 and December 31, 2015, the fair value of loaned securities held by separate accounts was approximately $27.5 billion and $28.8 billion, respectively, and the fair value of the collateral held under these securities lending agreements was approximately $29.8 billion and $31.3 billion, respectively. Recent Accounting Pronouncements Not Yet Adopted Revenue from Contracts with Customers. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). ASU 2014-09 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. In March 2016, the FASB issued ASU 2016-08, Principal Versus Agent Considerations (Reporting Revenue Gross Versus Net) In April 2016, the FASB issued ASU 2016-10, Identifying Performance Obligations and Licensing In May 2016, the FASB issued ASU 2016-12, Narrow-Scope Improvements and Practical Expedients The Company is currently evaluating the impact of adopting ASU 2014-09, ASU 2016-08, ASU 2016-10 and ASU 2016-12, which are effective for the Company on January 1, 2018. Recognition and Measurement of Financial Instruments . In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). ASU 2016-01 amends guidance on the classification and measurement of financial instruments, including significant revisions in accounting related to the classification and measurement of investments in equity securities and presentation of certain fair value changes for financial liabilities when the fair value option is elected. ASU 2016-01 also amends certain disclosure requirements associated with the fair value of financial instruments. The Company is currently evaluating the impact of adopting ASU 2016-01, which is effective for the Company on January 1, 2018. Leases. In February 2016, the FASB issued ASU 2016-02, Leases (“ASU 2016-02”). ASU 2016-02 requires lessees to recognize assets and liabilities arising from most operating leases on the statement of financial position. The Company is currently evaluating the impact of adopting ASU 2016-02, which is effective for the Company on January 1, 2019. Accounting for Share-Based Payments. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). ASU 2016-09 simplifies accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. ASU 2016-09 is effective for the Company on January 1, 2017. The Company does not expect the adoption of the forfeiture provision of ASU 2016-09 to be material to the condensed consolidated financial statements. The Company is currently evaluating the impact of adopting the other provisions of ASU 2016-09. Accounting for Credit Losses. In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which amends the guidance for evaluating the impairment of financial instruments. The new guidance adds an impairment model that is based on expected losses rather than incurred losses. The Company is currently evaluating the impact of adopting ASU 2016-13, which is effective for the Company on January 1, 2020 with early adoption permitted on January 1, 2019. Cash Flow Classification. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”), which amends and clarifies the current guidance to reduce diversity in practice of the classification of certain cash receipts and payments in the statement of cash flows. The Company is currently evaluating the impact of adopting ASU 2016-15, which is effective for the Company on January 1, 2018 with early adoption permitted. The Company must apply the guidance retrospectively to all periods presented. Income Taxes. In October 2016, the FASB issued ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory (“ASU 2016-16”), which removes the prohibition against the immediate recognition of the current and deferred income tax effects of intra-entity transfers of assets other than inventory. The Company is currently evaluating the impact of adopting ASU 2016-16, which is effective for the Company on January 1, 2018 with early adoption permitted on January 1, 2017. Interests Held through Related Parties That Are under Common Control. In October 2016, the FASB issued ASU 2016-17, Interests Held through Related Parties That Are under Common Control (“ASU 2016-17”), which alters how a decision maker needs to consider indirect interests in a variable interest entity (“VIE”) held through an entity under common control. The Company is currently evaluating the impact of adopting ASU 2016-17, which is effective for the Company on January 1, 2017 with early adoption permitted.

Equity method investments primarily include BlackRock’s direct investments in certain BlackRock sponsored investment funds. In addition, the Company accounts for its interest in PennyMac Financial Services, Inc. (“PennyMac”) as an equity method investment. At September 30, 2016 and December 31, 2015 the Company’s investment in PennyMac was excluded from the amounts in the table above and included in other assets on the condensed consolidated statements of financial condition. The carrying value and fair value of the Company’s interest (approximately 20% or 16 million shares and units) was approximately $270 million and $265 million, respectively, at September 30, 2016 and approximately $222 million and $239 million, respectively, at December 31, 2015. The fair value of the Company’s interest reflected the PennyMac stock price at September 30, 2016 and December 31, 2015, respectively (a Level 1 input). The Company performed an other-than-temporary impairment analysis as of September 30, 2016 and determined the decline in fair value below the carrying value to be temporary. Cost method investments include nonmarketable securities, primarily FRB stock, which is held for regulatory purposes and is restricted from sale. At September 30, 2016 and December 31, 2015, there were no indicators of impairment on these investments. Carried interest represents allocations to BlackRock’s general partner capital accounts from certain funds. These balances are subject to change upon cash distributions, additional allocations or reallocations back to limited partners within the respective funds.

Consolidated Voting Rights Entities	4. Consolidated Voting Rights Entities The Company consolidates certain sponsored investment funds accounted for as VREs because it is deemed to control such funds. The investments owned by these consolidated VREs are classified as trading investments. The following table presents the balances related to these consolidated VREs that were recorded on the condensed consolidated statements of financial condition, including BlackRock’s net interest in these funds: September 30, December 31, (in millions) 2016 2015 Cash and cash equivalents $ 60 $ 100 Trading investments 575 700 Other assets 14 18 Other liabilities (72 ) (77 ) Noncontrolling interests (64 ) (125 ) BlackRock’s net interests in consolidated VREs $ 513 $ 616 BlackRock’s total exposure to consolidated VREs represents the value of its economic ownership interest in these sponsored investment funds. Valuation changes associated with investments held at fair value by these consolidated VREs are reflected in nonoperating income (expense) and partially offset in net income (loss) attributable to noncontrolling interests for the portion not attributable to BlackRock. The Company cannot readily access cash and cash equivalents held by consolidated VREs to use in its operating activities.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Variable Interest Entities	5. Variable Interest Entities In the normal course of business, the Company is the manager of various types of sponsored investment vehicles, which may be considered VIEs Consolidated VIEs. The Company’s consolidated VIEs as of September 30, 2016 and December 31, 2015 include certain sponsored investment funds in which BlackRock has an investment and as the investment manager is deemed to have both the power to direct the most significant activities of the funds and the right to receive benefits (or the obligation to absorb losses) that could potentially be significant to these sponsored investment funds. 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. Consolidated VIE assets and liabilities are presented after intercompany eliminations at September 30, 2016 and December 31, 2015 in the following table: (in millions) September 30, 2016 December 31, 2015 Assets of consolidated VIEs: Cash and cash equivalents $ 161 $ 148 Investments 1,411 1,030 Other assets 183 67 Total investments and other assets 1,594 1,097 Liabilities of consolidated VIEs (272 ) (177 ) Noncontrolling interests of consolidated VIEs (593 ) (416 ) BlackRock's net interests in consolidated VIEs $ 890 $ 652 The Company recorded a $19 The Company recorded a $14 million nonoperating net loss and a $2 million nonoperating net gain, respectively, during the three and nine months ended September 30, 2015 related to consolidated VIEs. The net loss attributable to noncontrolling interests related to consolidated VIEs during the three and nine months ended September 30, 2015 was $9 million and $2 million, respectively. Nonconsolidated VIEs .

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 3 amounts include direct investments in private equity companies held by private equity funds. (4) Amounts primarily include recorded contingent liabilities related to certain acquisitions (see Note 11, Commitments and Contingencies Level 3 Assets. Level 3 investments of consolidated VIEs of $194 million and $196 million at September 30, 2016 and December 31, 2015, respectively, related to direct investments in private equity companies held by consolidated private equity funds. Direct investments in private equity companies may be valued using the market approach or the income approach, or a combination thereof, and were valued based on an assessment of each underlying investment, incorporating evaluation of additional significant third-party financing, changes in valuations of comparable peer companies, the business environment of the companies, market indices, assumptions relating to appropriate risk adjustments for nonperformance and legal restrictions on disposition, among other factors. The fair value derived from the methods used is evaluated and weighted, as appropriate, considering the reasonableness of the range of values indicated. Under the market approach, fair value may be determined by reference to multiples of market-comparable companies or transactions, including earnings before interest, taxes, depreciation and amortization (“EBITDA”) multiples. Under the income approach, fair value may be determined by discounting the expected cash flows to a single present value amount using current expectations about those future amounts. Unobservable inputs used in a discounted cash flow model may include projections of operating performance generally covering a five-year period and a terminal value of the private equity direct investment. For investments utilizing the discounted cash flow valuation technique, a significant increase (decrease) in the discount rate, risk premium or discount for lack of marketability in isolation could result in a significantly lower (higher) fair value measurement. For investments utilizing the market-comparable valuation technique, a significant increase (decrease) in the EBITDA multiple in isolation could result in a significantly higher (lower) fair value measurement. Level 3 assets may include investments in CLOs and bonds valued based on single-broker nonbinding quotes, and direct private equity investments valued using the market approach or the income approach as described above. Level 3 Liabilities. Level 3 other liabilities primarily include recorded contingent liabilities related to certain acquisitions, which were valued based upon discounted cash flow analyses using unobservable market data inputs.

In addition, at September 30, 2016 and December 31, 2015, approximately $34 million and $68 million, respectively, of money market funds were recorded within cash and cash equivalents of consolidated VIEs. Money market funds are valued based on quoted market prices, or $1.00 per share, which generally is the NAV of the fund. (3) The carrying amounts of accounts receivable, accounts payable and accrued liabilities approximate fair value due to their short-term nature. (4) Long-term borrowings are recorded at amortized cost net of unamortized debt issuance costs. The fair value of the long-term borrowings, including the current portion of long-term borrowings, is estimated using market prices at the end of September 2016 and December 2015, respectively. See Note 10, Borrowings Investments in Certain Entities that Calculate Net Asset Value 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.

Total consideration included $75 million of contingent consideration at fair value at time of close. BlackRock’s platform provides clients with broad access to high quality, global liquidity investment solutions. (2) The decrease in goodwill during the nine months ended September 30, 2016 primarily resulted from a decline related to tax benefits realized from tax-deductible goodwill in excess of book goodwill from the acquisition of the fund-of-funds business of Quellos Group, LLC in October 2007 (the “Quellos Transaction”). Goodwill related to the Quellos Transaction will continue to be reduced in future periods by the amount of tax benefits realized from tax-deductible goodwill in excess of book goodwill from the Quellos Transaction.

The Company’s credit facility has an aggregate commitment amount of $4.0 billion and was amended in April 2016 to extend the maturity date to March 2021 (the “2016 credit facility”). The 2016 credit facility permits the Company to request up to an additional $1.0 billion of borrowing capacity, subject to lender credit approval, increasing the overall size of the 2016 credit facility to an aggregate principal amount not to exceed $5.0 billion. Interest on borrowings outstanding accrues at a rate based on the applicable London Interbank Offered Rate plus a spread.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	11. Commitments and Contingencies Investment Commitments. At September 30, 2016, the Company had $194 million of various capital commitments to fund sponsored investment funds, including consolidated VIEs. These funds 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. In addition to the capital commitments of $194 million, the Company had approximately $12 million of contingent commitments for certain funds which have investment periods that have expired. 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 condensed 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 Contingent Payments Related to Business Acquisitions . In connection with certain acquisitions, BlackRock is required to make contingent payments, subject to achieving specified performance targets, which may include revenue related to acquired contracts or new capital commitments for certain products. The fair value of the remaining aggregate contingent payments at September 30, 2016 totaled $118 million, including $76 million related to the BofA Global Capital Management transaction, and is included in other liabilities on the condensed consolidated statement of financial condition. Other Contingent Payments. The Company acts as the portfolio manager in a series of derivative transactions and has a maximum potential exposure of $17 million between the Company and counterparty. See Note 7, , for further discussion. Legal Proceedings. From time to time, BlackRock receives subpoenas or other requests for information from various U.S. federal, state governmental and domestic and international regulatory authorities in connection with certain industry-wide or other investigations or proceedings. It is BlackRock’s policy to cooperate fully with such inquiries. The Company and certain of its subsidiaries 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. On May 27, 2014, certain purported investors in the BlackRock Global Allocation Fund, Inc. and the BlackRock Equity Dividend Fund (collectively, the “Funds”) filed a consolidated complaint (the “Consolidated Complaint”) in the U.S. District Court for the District of New Jersey against BlackRock Advisors, LLC, BlackRock Investment Management, LLC and BlackRock International Limited (collectively, the “Defendants”) under the caption In re BlackRock Mutual Funds Advisory Fee Litigation Between November 12, 2015 and November 16, 2015, BlackRock, Inc., BlackRock Realty Advisors, Inc. (“BRA”) and the BlackRock Granite Property Fund, Inc. (“Granite Fund”), along with certain other Granite Fund-related entities (collectively, the “BlackRock Parties”) were named as defendants in thirteen separate lawsuits filed in the Superior Court of the State of California for the County of Alameda arising out of the June 16, 2015 collapse of a balcony at the Library Gardens apartment complex in Berkeley, California (the “Property”). The Property is indirectly owned by the Granite Fund, which is managed by BRA. The plaintiffs also named as defendants in the lawsuits Greystar, which is the property manager of the Property, and certain other entities, including the developer of the Property, building contractors and building materials suppliers. The plaintiffs allege, among other things, that the BlackRock Parties were negligent in their ownership, control and maintenance of the Property’s balcony, and seek monetary, including punitive, damages. Additionally, on March 16, 2016, three former tenants of the Library Gardens apartment unit that experienced the balcony collapse sued the BlackRock Parties. The former tenants, who witnessed (but were not physically injured in) the accident make allegations virtually identical to those in the previously filed actions and claim that as a result of the collapse, they suffered unspecified emotional damage. Several defendants have also filed cross-complaints alleging a variety of claims, including claims against the BlackRock Parties for contribution, negligence, and declaratory relief. BlackRock believes the claims against it are without merit and intends to vigorously defend the actions. 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 condensed consolidated statements of financial condition. In connection with securities lending transactions, BlackRock has issued certain indemnifications to 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. At September 30, 2016, the Company indemnified certain of its clients for their securities lending loan balances of approximately $171.8 billion. The Company held as agent, cash and securities totaling $182.5 billion as collateral for indemnified securities on loan at September 30, 2016. The fair value of these indemnifications was not material at September 30, 2016.

Earnings Per Share [Abstract]
Earnings Per Share	18. Earnings Per Share Due to the similarities in terms between BlackRock nonvoting participating preferred stock and the Company’s common stock, the Company considers its participating preferred stock to be a common stock equivalent for purposes of earnings per share (“EPS”) calculations. As such, the Company has included the outstanding nonvoting participating preferred stock in the calculation of average basic and diluted shares outstanding. The following table sets forth the computation of basic and diluted EPS for the three and nine months ended September 30, 2016 and 2015 under the treasury stock method: Three Months Ended Nine Months Ended September 30, September 30, (in millions, except shares and per share data) 2016 2015 2016 2015 Net income attributable to BlackRock $ 875 $ 843 $ 2,321 $ 2,484 Basic weighted-average shares outstanding 164,129,214 166,045,291 164,756,355 166,579,805 Dilutive effect of nonparticipating RSUs and stock options 2,127,384 2,620,012 2,004,557 2,577,383 Total diluted weighted-average shares outstanding 166,256,598 168,665,303 166,760,912 169,157,188 Basic earnings per share $ 5.33 $ 5.08 $ 14.09 $ 14.91 Diluted earnings per share $ 5.26 $ 5.00 $ 13.92 $ 14.68

Significant Accounting Policies (Policies)	9 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation . These condensed 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 on the condensed consolidated statements of financial condition represents the portion of consolidated sponsored investment funds in which the Company does not have direct equity ownership. Accounts and transactions between consolidated entities have been eliminated. 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 financial information that normally is included in annual financial statements, including certain financial statement footnotes, is not required for interim reporting purposes and has been condensed or omitted herein. These condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and notes related thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015, which was filed with the Securities and Exchange Commission (“SEC”) on February 26, 2016 (“2015 Form 10-K”). The interim financial information at September 30, 2016 and for the three and nine months ended September 30, 2016 and 2015 is unaudited. However, in the opinion of management, the interim information includes all normal recurring adjustments necessary for the fair presentation of the Company’s results for the periods presented. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year. Certain items previously reported have been reclassified to conform to the current year presentation.
Recent Accounting Pronouncements Adopted in the Nine Months Ended September 30, 2016	Recent Accounting Pronouncements Adopted in the Nine Months Ended September 30, 2016 Accounting for Measurement-Period Adjustments . In September 2015, the Financial Accounting Standards Board (“FASB”) issued ASU 2015-16, (“ASU 2015-16”). Under ASU 2015-16, an acquirer must recognize, upon determination, adjustments to the original amounts recorded for a business acquisition that are identified during the one-year period following the acquisition date. Previously, prior period information was required to be restated. The Company adopted ASU 2015-16 prospectively on January 1, 2016 and will apply the ASU to any adjustments related to business acquisitions. Transition to Equity Method Accounting. In March 2016, the FASB issued ASU 2016-07, (“ASU 2016-07”). ASU 2016-07 eliminates the requirement to apply the equity method of accounting retrospectively to an investment that subsequently qualifies for such accounting as a result of obtaining significant influence. The Company adopted ASU 2016-07 prospectively on January 1, 2016.
Fair Value Measurements	Fair Value Measurements. Hierarchy of Fair Value Inputs . The Company uses a fair value hierarchy that prioritizes inputs to valuation techniques 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 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, investments in collateralized loan obligations (“CLOs”), short-term floating-rate notes, asset-backed securities, securities held within consolidated hedge funds, restricted public securities valued at a discount, as well as over-the-counter derivatives, including interest and inflation 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 held within consolidated funds and investments in CLOs. • Level 3 liabilities include contingent liabilities related to acquisitions valued primarily based upon discounted cash flow analysis using unobservable market data. 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 Techniques. The fair values of certain Level 3 assets and liabilities were determined using various methodologies as appropriate, including third-party pricing vendors, broker quotes and market and income approaches. Such quotes and modeled prices are evaluated for reasonableness through various procedures, including due diligence reviews of third-party pricing vendors, variance analyses, consideration of the current market environment and other analytical procedures. A significant number of inputs used to value equity, debt securities and investments in CLOs is 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 or as Level 2 for other similar securities if the vendor uses observable inputs in determining the price. Annually, BlackRock’s internal valuation committee or other designated groups review both the valuation methodologies, including the general assumptions and methods used to value various asset classes, and operational processes with these vendors. On a quarterly basis, meetings are held with key vendors to identify any significant changes to the vendors’ processes. 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 NAV as the fair value for certain investments. The inputs to value these investments may include BlackRock 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 generally 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.
Derivative Instruments and Hedging Activities	Derivative Instruments 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 exposures for certain seed investments. However, certain consolidated sponsored investment funds may also invest in derivatives as a part of their investment strategy. 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 currency-denominated assets or liabilities or hedged investments, on the condensed 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 different from U.S. dollars. The gain or loss from revaluing accounting hedges of net investments in foreign operations at the spot rate is deferred and reported within accumulated other comprehensive income on the condensed consolidated statements of financial condition. The Company reassesses the effectiveness of its net investment hedge on a quarterly basis.
Money Market Fee Waivers	Money Market Fee Waivers . The Company is currently voluntarily waiving a portion of its management fees on certain money market funds to ensure that they maintain a minimum level of daily net investment income (the “Yield Support waivers”). During the three and nine months ended September 30, 2016, these waivers resulted in a reduction of management fees of approximately $17 million and $42 million, respectively. During the three and nine months ended September 30, 2015, these waivers resulted in a reduction of management fees of approximately $32 million and $112 million, respectively. Approximately 45% of year-to-date Yield Support waivers for both nine months ended September 30, 2016, and 2015 were offset by a reduction of BlackRock’s distribution and servicing costs paid to a financial intermediary. BlackRock has provided Yield Support waivers in prior periods and may increase or decrease the level of fee waivers in future periods.
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, 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 condensed 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 condensed 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 condensed 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 legal title to the collateral with minimum values generally ranging 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. The Company records on the condensed consolidated statements of financial condition the cash and noncash collateral received under these BlackRock Life Limited securities lending arrangements as its own asset in addition to an equal and offsetting collateral liability for the obligation to return the collateral. 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 condensed consolidated statements of income. During the nine months ended September 30, 2016 and 2015, the Company had not resold or repledged any of the collateral received under these arrangements. At September 30, 2016 and December 31, 2015, the fair value of loaned securities held by separate accounts was approximately $27.5 billion and $28.8 billion, respectively, and the fair value of the collateral held under these securities lending agreements was approximately $29.8 billion and $31.3 billion, respectively.
Recent Accounting Pronouncements Not Yet Adopted	Recent Accounting Pronouncements Not Yet Adopted Revenue from Contracts with Customers. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). ASU 2014-09 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. In March 2016, the FASB issued ASU 2016-08, Principal Versus Agent Considerations (Reporting Revenue Gross Versus Net) In April 2016, the FASB issued ASU 2016-10, Identifying Performance Obligations and Licensing In May 2016, the FASB issued ASU 2016-12, Narrow-Scope Improvements and Practical Expedients The Company is currently evaluating the impact of adopting ASU 2014-09, ASU 2016-08, ASU 2016-10 and ASU 2016-12, which are effective for the Company on January 1, 2018. Recognition and Measurement of Financial Instruments . In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). ASU 2016-01 amends guidance on the classification and measurement of financial instruments, including significant revisions in accounting related to the classification and measurement of investments in equity securities and presentation of certain fair value changes for financial liabilities when the fair value option is elected. ASU 2016-01 also amends certain disclosure requirements associated with the fair value of financial instruments. The Company is currently evaluating the impact of adopting ASU 2016-01, which is effective for the Company on January 1, 2018. Leases. In February 2016, the FASB issued ASU 2016-02, Leases (“ASU 2016-02”). ASU 2016-02 requires lessees to recognize assets and liabilities arising from most operating leases on the statement of financial position. The Company is currently evaluating the impact of adopting ASU 2016-02, which is effective for the Company on January 1, 2019. Accounting for Share-Based Payments. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). ASU 2016-09 simplifies accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. ASU 2016-09 is effective for the Company on January 1, 2017. The Company does not expect the adoption of the forfeiture provision of ASU 2016-09 to be material to the condensed consolidated financial statements. The Company is currently evaluating the impact of adopting the other provisions of ASU 2016-09. Accounting for Credit Losses. In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which amends the guidance for evaluating the impairment of financial instruments. The new guidance adds an impairment model that is based on expected losses rather than incurred losses. The Company is currently evaluating the impact of adopting ASU 2016-13, which is effective for the Company on January 1, 2020 with early adoption permitted on January 1, 2019. Cash Flow Classification. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”), which amends and clarifies the current guidance to reduce diversity in practice of the classification of certain cash receipts and payments in the statement of cash flows. The Company is currently evaluating the impact of adopting ASU 2016-15, which is effective for the Company on January 1, 2018 with early adoption permitted. The Company must apply the guidance retrospectively to all periods presented. Income Taxes. In October 2016, the FASB issued ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory (“ASU 2016-16”), which removes the prohibition against the immediate recognition of the current and deferred income tax effects of intra-entity transfers of assets other than inventory. The Company is currently evaluating the impact of adopting ASU 2016-16, which is effective for the Company on January 1, 2018 with early adoption permitted on January 1, 2017. Interests Held through Related Parties That Are under Common Control. In October 2016, the FASB issued ASU 2016-17, Interests Held through Related Parties That Are under Common Control (“ASU 2016-17”), which alters how a decision maker needs to consider indirect interests in a variable interest entity (“VIE”) held through an entity under common control. The Company is currently evaluating the impact of adopting ASU 2016-17, which is effective for the Company on January 1, 2017 with early adoption permitted.

Goodwill And Intangible Assets Disclosure [Abstract]
Goodwill Activity	Goodwill activity during the nine months ended September 30, 2016 was as follows: (in millions) December 31, 2015 $ 13,123 BofA Global Capital Management (1) 15 Goodwill adjustment related to Quellos (2) (14 ) September 30, 2016 $ 13,124 (1) The $15 million increase represents goodwill from the BofA Global Capital Management transaction in April 2016 that transferred investment management responsibilities of approximately $80.6 billion of cash assets under management to the Company. Total consideration included $75 million of contingent consideration at fair value at time of close. BlackRock’s platform provides clients with broad access to high quality, global liquidity investment solutions. (2) The decrease in goodwill during the nine months ended September 30, 2016 primarily resulted from a decline related to tax benefits realized from tax-deductible goodwill in excess of book goodwill from the acquisition of the fund-of-funds business of Quellos Group, LLC in October 2007 (the “Quellos Transaction”). Goodwill related to the Quellos Transaction will continue to be reduced in future periods by the amount of tax benefits realized from tax-deductible goodwill in excess of book goodwill from the Quellos Transaction. The balance of the Quellos tax-deductible goodwill in excess of book goodwill was approximately $208 million and $231 million at September 30, 2016 and December 31, 2015, respectively.
