Accounting Pronouncements Adopted in the Three Months Ended March 31, ~~2017.~~2018.

~~Accounting for Share-Based Payments.~~Revenue from Contracts with Customers. ~~In March 2016, the~~ The Financial Accounting Standards Board (“FASB”) issued ~~ASU 2016-09,~~ ~~Improvements to Employee Share-Based Payment~~ Accounting Standards Update (“ASU”) 2~~(“ASU 2016-09”~~014-09, Revenue from Contracts with Customers, and several amendments (collectively, “ASU 2014-09”). ASU ~~2016-09 simplifies~~2014-09 outlines a single comprehensive model for entities to use in accounting for ~~employee share-based payment transactions,~~revenue arising from contracts with customers and supersedes most previous revenue recognition guidance, including industry-specific guidance. The guidance also changes the accounting for ~~income taxes, forfeitures,~~certain contract costs and ~~statutory tax withholding requirements,~~revises the criteria for determining if an entity is acting as a principal or agent in certain arrangements.

The Company adopted ASU 2014-09 effective January 1, 2018 on a full retrospective basis, which required the Company to recast 2016 and 2017 previously reported amounts. The key impact of the standard relates to the Company’s presentation of certain revenue contracts and associated contract costs. The most significant of these changes relates to the presentation of certain distribution costs, which were previously presented net against revenue (contra-revenue) and are now presented as an expense on a gross basis. Revenue recognition related to investment advisory, administration fees and securities lending revenue as well as performance fees remained unchanged, which represents a substantial portion of the Company’s revenue. However, under ASU 2014-09, the Company may recognize certain performance fees, including carried interest, earlier than under the prior revenue recognition guidance. The impact to the condensed consolidated statement of financial condition upon adoption was related to a change in timing of recognition for certain technology and risk management revenue and related costs that resulted in an increase to other assets and other liabilities of $19 million and $25 million, respectively. The cumulative adjustment to retained earnings as of January 1, 2016 was a net decrease of $6 million.

The following table presents the impact of the adoption to the condensed consolidated statement of income for the three months ended March 31, 2017.

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 requiring an entity to measure substantially all equity securities (other than those accounted for under the equity method of accounting) at fair value through earnings. ASU 2016-01 also amends certain disclosure requirements associated with the fair value of financial instruments. The Company adopted ASU 2016-01 using a modified retrospective approach on January 1, 2018. The reclassification of unrealized gains (losses) on equity securities within accumulated other comprehensive income to retained earnings was not material upon adoption.

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 consolidated statement of cash flows. The Company adopted ASU ~~2016-09 as of~~2016-15 on January 1, ~~2017.~~2018 retrospectively to all periods presented. The adoption of ASU ~~2016-09 requires all excess tax benefits and~~

deficiencies to be recognized in income tax expense on the consolidated statements of income. Accordingly, the Company recorded a discrete income tax benefit of $81 million during the three months ended March 31, 2017 for vested restricted stock units where the grant date stock price was lower than the vesting date stock price. The new guidance will increase the volatility of income tax expense as a result of fluctuations in the Company’s stock price. Upon adoption, the Company elected to account for forfeitures as they occur, which2016-15 did not have a material impact on the condensed consolidated ~~financial statements.~~ statement of cash flows.

Restricted Cash. In ~~addition,~~November 2016, the FASB issued 2016-18, Restricted Cash, which clarifies the classification and presentation of restricted cash in the statement of cash flows (“ASU 2016-18”). The Company ~~elected~~adopted ASU 2016-18 on January 1, 2018 retrospectively to ~~present excess tax benefits and deficiencies prospectively in operating activities~~all periods presented. The adoption of ASU 2016-18 did not have a material impact on the condensed consolidated statement of cash flows. See Note 3, Cash, Cash Equivalents and Restricted Cash, for additional disclosure requirements related to restricted cash.

Reclassifications from Accumulated Other Comprehensive Income.In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“ASU 2018-02”). ASU 2018-02 allows reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The Company adopted ASU 2018-02 prospectively on January 1, 2018. The adoption of ASU 2018-02 did not have a material impact on the condensed consolidated statement of financial condition.

Revenue is recognized upon transfer of control of promised services to customers in an amount that reflects consideration to which the Company expects to be entitled in exchange for those services (the “transaction price”). 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 as part of its transaction price 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. Such fees are primarily based on agreed-upon percentages of net asset value, assets under management (“AUM”) or committed capital. These 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 fees waived pursuant to contractual expense limitations of the funds or voluntary 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 advisors on a gross basis in the condensed consolidated statements of income where it is deemed to be the principal.

The Company earns revenue by lending securities on behalf of clients, primarily to highly rated banks and broker-dealers. 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.

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 may vary by product or account, and include monthly, quarterly, annually or longer measurement periods. 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.

The Company is allocated carried interest from certain alternative investment products upon exceeding performance thresholds. BlackRock may be required to reverse/return all, or part, of such carried interest allocations depending upon future performance of these funds. Therefore, carried interest subject to such clawback provisions is recorded in investments/investments of consolidated VIEs or cash/cash of consolidated VIEs to the extent that it is distributed, on its condensed consolidated statements of financial condition.

Performance fees, including carried interest, are recognized when it is determined that they are no longer probable of significant reversal (such as upon the sale of a fund’s investment or when the amount of AUM becomes known as of the end of a specified measurement period). Significant judgement is involved in making such determination. At each reporting date, the Company considers various factors in estimating performance fees to be recognized, including carried interest. These factors include but are not limited to whether: (1) the fees are dependent on the market and thus are highly susceptible to factors outside the Company’s influence; (2) the fees have a large number and a broad range of possible amounts; and (3) the funds or separately managed accounts have the ability to invest or reinvest its sales proceeds.

The Company records a contract 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. At March 31, 2018 and December 31, 2017, the Company had $224 million and $219 million, respectively, of deferred carried interest recorded in other liabilities/other liabilities of consolidated VIEs on the condensed consolidated statements of financial condition. 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, for these products is unknown.

Technology and risk management revenue. BlackRock offers investment management technology systems, risk management services, wealth management and digital distribution tools on a fee basis. Clients include banks, insurance companies, official institutions, pension funds, asset managers, retail distributors and other investors. Fees earned for technology and risk management revenue are recorded as services are performed and are generally determined using the value of positions on the Aladdin platform or on a fixed-rate basis.

Distribution Fees. The Company accounts for fund distribution services and shareholder servicing as distinct services, separate from fund management services, because customers can benefit from each of the services on their own and because the services are separately identifiable (that is, the nature of the promised services is to transfer each service individually). The Company records upfront and ongoing sales commissions as distribution fee revenue for serving as the principal underwriter and/or distributor for certain mutual funds that it manages. The Company recognizes the upfront fees for front-end load funds on a trade date basis when the services are performed and the amount the Company is entitled to is known. The on-going distribution fees are generally based on net asset values and are recognized when the amount is known. Distribution services are satisfied at a point in time. Consequently, a portion of the on-going distribution fees the Company recognized may be related to the services performed in prior periods that met the recognition criteria in the current period. The Company recognizes ongoing shareholder servicing fee revenue when and as shareholder services are performed over time. The Company contracts with third parties for various fund distribution services and shareholder servicing of certain funds to be performed on its behalf. These arrangements are generally priced as a portion of the fee paid to the Company by the fund or as an agreed-upon percentage of net asset value. The Company presents its distribution fees and distribution and servicing costs incurred on a gross basis in the condensed consolidated statements of income as it is deemed to be the principal in such transactions.

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 investments.

Advisory services fees are determined using fixed-rate fees and are recognized over time as the related services are performed.

Commissions related to transition management services are recorded on a trade-date basis as securities transactions occur.

Investments in Debt Securities. BlackRock classifies debt investments as available-for-sale, held-to-maturity or trading based on the Company’s intent to sell the security or, its intent and ability to hold the debt security to maturity.

Available-for-sale debt securities are those securities that are not classified as trading or held-to-maturity. Available-for-sale debt securities include certain investments in collateralized loan obligations (“CLOs”) and are carried at fair value on the condensed consolidated statements of financial condition with changes in fair value recorded in the accumulated other comprehensive income (loss) component of stockholders’ equity in the period of the change. Upon the disposition of an available-for-sale security, the Company reclassifies the gain or loss on the security from accumulated other comprehensive income (loss) to nonoperating income (expense) on the condensed consolidated statements of income.

Held-to-maturity debt securities are purchased with the positive intent and ability to be held to maturity and are recorded at amortized cost on the condensed 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 condensed consolidated statements of financial condition with changes in fair value recorded in nonoperating income (expense) on the condensed consolidated statements of income in the period of the change. Trading securities include certain investments in 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 condensed consolidated statements of financial condition with changes in the fair value recorded through net income (“FVTNI”) within nonoperating income (expense) in the period of change. For nonmarketable equity securities, the Company generally elected to apply the practicality exception to apply 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 in the condensed consolidated statements of income in the period of the change. Dividends received from the investment are recorded as dividend income within nonoperating income (expense).

Equity Method. For equity investments where BlackRock does not control the investee, and where it is not the primary beneficiary (“PB”) of a VIE, but can exert significant influence over the financial and operating policies of the investee, the Company follows the equity method of accounting. BlackRock’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 investments since such companies are considered to be an extension of BlackRock’s core business. BlackRock’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 condensed consolidated statement of financial condition. Distributions received from the investment reduce the Company’s carrying value of the investee and the cost basis if deemed to be a return of capital.

Impairments of Investments. Management periodically assesses equity method, available-for-sale and held-to-maturity investments for other-than-temporary impairment (“OTTI”). If an OTTI exists, an impairment charge would be recorded in the condensed consolidated statements of income.

For equity method investments and held-to-maturity investments, if circumstances indicate that an OTTI may exist, the investments are evaluated using market values, where available, or the expected future cash flows of the investment. If the Company determines an OTTI exists, an impairment charge is recognized for the excess of the carrying amount of the investment over its estimated fair value.

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. An impairment charge is recognized for the excess of the carrying amount of the investment over its estimated fair value.

In addition, for nonmarketable equity securities that are accounted for under the measurement alternative to fair value, the Company applies the simplified impairment model that does not require the Company to consider whether the impairment is other than temporary.

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:

Quoted prices (unadjusted) in active markets for identical assets or liabilities at the reporting date.

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.

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.

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. 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 and 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 approaches, 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 net asset value (“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 utilize 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-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 not 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~~may voluntarily ~~waiving~~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”). During the three months ended March 31, 2018 and 2017, ~~and 2016, these~~ waivers that resulted in a reduction of management fees ~~of approximately $6million and $12 million, respectively. Approximately 0% and 83% of Yield Support waivers for the three months ended March 31, 2017 and 2016, respectively,~~ were ~~offset by a reduction of BlackRock’s distribution and servicing costs paid to a financial intermediary.~~immaterial. BlackRock ~~has provided Yield Support waivers in prior periods and~~ may increase or decrease the level of ~~fee~~Yield Support 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 three months ended March 31, ~~2017~~2018 and ~~2016,~~2017, the Company had not resold or repledged any of the collateral received under these arrangements. At March 31, ~~2017~~2018 and December 31, ~~2016,~~2017, the fair value of loaned securities held by separate accounts was approximately ~~$27.5~~$24.8 billion and ~~$25.7~~$22.3 billion, respectively, and the fair value of the collateral held under these securities lending agreements was approximately ~~$30.0~~$27.2 billion and ~~$27.8~~$24.2 billion, respectively.

~~Revenue from Contracts with Customers.~~Leases. ~~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. The guidance also changes the accounting for certain contract costs and revises the criteria for determining if an entity is acting as a principal or agent in certain arrangements. The Company continues to evaluate the impact of ASU 2014-09 on the presentation and recognition of its revenue contracts and certain contract costs. The most significant change identified to date relates to the presentation of certain distribution costs, which are currently presented net against revenues (contra-revenue) and will likely be presented as an expense on a gross basis. The Company will adopt ASU 2014-09 upon its effective date of January 1, 2018, together with all amending ASUs, and is currently evaluating which transition method it will apply.

~~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. ASU 2016-01 is effective for the Company on January 1, 2018. In the period of adoption, the Company is required to reclassify the unrealized gains/losses on equity securities within accumulated other comprehensive income to retained earnings, which is not expected to be material to the condensed consolidated financial statements.

~~Leases.~~In February 2016, the FASB issued ASU 2016-02, Leases (“ASU 2016-02”)~~. ASU 2016-02~~, which requires lessees to recognize assets and liabilities arising from most operating leases on the ~~statement~~condensed consolidated statements of financial ~~position.~~condition.

~~Cash Flow Classification.~~ ~~In August 2016,~~2019, and the ~~FASB issued ASU 2016-15,~~ ~~Classification of Certain Cash Receipts and Cash Payments~~ ~~(“ASU 2016-15”), which amends and clarifies~~Company intends to apply the ~~current guidance to reduce diversity in practice~~practical expedients allowed by the standard upon transition.

At December 31, 2016, trading investments included $246 million of debt securities and $219 million of equity securities held by consolidated sponsored investment funds accounted for as VREs, $59 million of certain deferred compensation plan mutual fund investments and $101 million of other equity and debt securities.

~~Equity method investments primarily include BlackRock’s direct investments in certain BlackRock sponsored investment funds.~~15

In addition, the Company accounts for its interest in PennyMac Financial Services, Inc. (“PennyMac”) as an equity method investment. At March 31, ~~2017~~2018 and December 31, ~~2016~~2017 the Company’s investment in PennyMac was excluded from ~~the amounts~~investments 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 ~~$305~~$363 million and ~~$265~~$352 million, respectively, at March 31, ~~2017~~2018 and approximately ~~$301~~$342 million and ~~$259~~$348 million, respectively, at December 31, ~~2016.~~2017. The fair value of the Company’s interest reflected the PennyMac stock price at March 31, ~~2017~~2018 and December 31, ~~2016,~~2017, respectively (a Level 1 input). The ~~Company performed an other-than-temporary impairment analysis as~~fair value of the Company’s interest in the non-public units held of PennyMac is based on the stock price of the PennyMac public securities at March 31, ~~2017 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 March 31, 2017~~2018 and December 31, ~~2016, 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.2017.

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:

BlackRock’s net interests in consolidated VREs	$	630		$	444		$	480		$	460

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.

In the normal course of business, the Company is the manager of various types of sponsored investment vehicles, which may be considered variable interest entities (“VIEs”). The Company may from time to time own equity or debt securities or enter into derivatives 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 investments in the entity. The Company consolidates entities when it is determined to be the ~~primary beneficiary (“PB”).~~PB.

Consolidated VIEs. The Company’s consolidated VIEs 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 in the following table:

Level 3 Assets. Level 3 investments of consolidated VIEs of ~~$113 million and $112~~$116 million at both March 31, ~~2017~~2018 and December 31, ~~2016, respectively,~~2017, 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 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.

Realized and Unrealized Gains (Losses) for Level 3 Assets and Liabilities. Realized and unrealized gains (losses) recorded for Level 3 assets and liabilities are reported in nonoperating income (expense) on the condensed consolidated statements of income. A portion of net income (loss) for consolidated sponsored investment funds ~~are~~is allocated to noncontrolling interests 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, or when the carrying value of certain equity method investments no longer represents fair value as determined under valuation methodologies.

Disclosures of Fair Value for Financial Instruments Not Held at Fair Value. At March 31, ~~2017~~2018 and December 31, ~~2016,~~2017, the fair value of the Company’s financial instruments not held at fair value are categorized in the table below:

Investments in Certain Entities that Calculate Net Asset Value Per ~~Share.~~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).

^(e) This category includes the underlying third-party private equity funds within consolidated BlackRock sponsored private equity funds of funds. The fair values of the investments in the third-party funds have been estimated using capital accounts representing the Company’s ownership interest in each fund in the portfolio as well as other performance inputs. These investments are not subject to redemption; however, for certain funds, the Company may sell or transfer its interest, which may need approval by the general partner of the underlying funds. Due to the nature of the investments in this category, the Company reduces its investment by distributions that are received through the realization of the underlying assets of the funds. It is estimated that the underlying assets of these funds will be liquidated over a weighted-average period of approximately five years at both March 31, ~~2017~~2018 and December 31, ~~2016.~~2017. The total remaining unfunded commitments to other third-party funds were ~~$16~~$18 million and $20 million at ~~both~~ March 31, ~~2017~~2018 and December 31, ~~2016.~~2017, respectively. The Company had contractual obligations to the consolidated funds of ~~$24~~$23 million at both March 31, ~~2017~~2018 and December 31, ~~2016.~~2017.

The Company maintains a program to enter into swaps to hedge against market price and interest rate exposures with respect to certain seed investments in sponsored investment products.

At December 31, 2017, the Company had outstanding total return swaps ~~and interest rate swaps~~ with an aggregate notional ~~values~~value of approximately $698 million and $41 million, respectively. At December 31, 2016, the Company had outstanding total return swaps and interest rate swaps with aggregate notional values of approximately $572 million and $42 million, respectively.$587 million.

Gains (losses) on ~~the~~ total return swaps ~~are~~ recorded in nonoperating income (expense) were not material for the three months ended March 31, 2018 and were $(35) million for the three months ended March 31, 2017. ~~Gains (losses) on total return swaps were not material for the three months ended March 31, 2016.~~

Gains (losses) on ~~the~~ interest rate swaps are recorded in nonoperating income (expense) and were not material for the three months ended March 31, 2018 and 2017.

~~The~~the Company ~~has entered into~~had a derivative providing credit protection ~~to a counterparty~~ of approximately $17 million to a counterparty, representing the Company’s maximum risk of loss with respect to the provision of credit protection. The Company carries the derivative at fair value based on the expected discounted future cash outflows under the arrangement.

The Company executes forward foreign currency exchange contracts to mitigate the risk of certain foreign exchange movements. At both March 31, ~~2017~~2018 and December 31, ~~2016,~~2017, the Company had outstanding forward foreign currency exchange contracts with aggregate notional values of approximately ~~$728~~$1.5 billion. The fair value of the outstanding forward foreign currency exchange contracts was $35 million at March 31, 2018 and ~~$107 million, respectively.~~was not material at December 31, 2017.

Gains (losses) on the forward foreign currency exchange contracts are recorded in other general and administration expense and were $30 million for the three months ended March 31, 2018.

~~2017~~2018 Revolving Credit Facility. The Company’s credit facility has an aggregate commitment amount of $4.0 billion and was amended in April ~~2017~~2018 to extend the maturity date to ~~April 2022~~March 2023 (the ~~“2017~~“2018 credit facility”). The ~~2017~~2018 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 ~~2017~~2018 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. The ~~2017~~2018 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 March 31, ~~2017.~~2018. The ~~2017~~2018 credit facility provides back-up liquidity to fund ongoing working capital for general corporate purposes and various investment opportunities. At March 31, ~~2017,~~2018, the Company had no amount outstanding under the ~~2017~~ credit facility.

Commercial Paper Program. The Company can issue unsecured commercial paper notes (the “CP Notes”) on a private-placement basis up to a maximum aggregate amount outstanding at any time of $4.0 billion. The commercial paper program is currently supported by the ~~2017~~2018 credit facility. At March 31, ~~2017,~~2018, BlackRock had no CP Notes outstanding.

~~2027 Notes~~. In March 2017, the Company issued $700 million in aggregate principal amount of 3.20% senior unsecured and unsubordinated notes maturing on March 15, 2027 (the “2027 Notes”). The net proceeds of the 2027 Notes were used towards the redemption of 6.25% notes in April 2017. Interest is payable semi-annually on March 15 and September 15 of each year, commencing September 15, 2017, and is approximately $22 million per year. The 2027 Notes may be redeemed prior to maturity at any time in whole or in part at the option of the Company at a “make-whole” redemption price. The unamortized discount and debt issuance costs are being amortized over the remaining term of the 2027 Notes.

See Note 12, Borrowings, in the ~~2016~~2017 Form 10-K for more information regarding the Company’s borrowings.

Investment Commitments. At March 31, ~~2017,~~2018, the Company had ~~$226~~$304 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 $226 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.

Lease Commitment. In May 2017, the Company entered into an agreement with 50 HYMC Owner LLC, for the lease of approximately 847,000 square feet of office space located at 50 Hudson Yards, New York, New York. The term of the lease is twenty years from the date that rental payments begin, expected to occur in May 2023, with the option to renew for a specified term. The lease requires annual base rental payments of approximately $51 million per year during the first five years of the lease term, increasing every five years to $58 million, $66 million and $74 million per year (or approximately $1.2 billion in base rent over its twenty-year term).

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 March 31, ~~2017~~2018 totaled ~~$113~~$242 million, and is included in other liabilities on the condensed consolidated ~~statement~~statements of financial condition.

Other Contingent Payments.The Company acts as the portfolio manager in a ~~series of~~ derivative ~~transactions~~transaction and has a maximum potential exposure of $17 million between the Company and counterparty. See Note 7,8, Derivatives and Hedging, 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~~regulatory authorities 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~~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.

for the District of New Jersey against BlackRock Advisors, LLC, BlackRock Investment Management, LLC and BlackRock International Limited under the caption In re BlackRock Mutual Funds Advisory Fee Litigation. The Consolidated Complaint, which purports to be brought derivatively on behalf of the Funds, alleges that the defendants violated Section 36(b) of the Investment Company Act by receiving allegedly excessive investment advisory fees from the Funds. On February 24, 2015, the same plaintiffs filed another complaint in the same court against BlackRock Investment Management, LLC and BlackRock Advisors, LLC. The allegations and legal claims in both complaints are substantially similar, with the new complaint purporting to challenge fees received by defendants after the plaintiffs filed their prior complaint. Both complaints seek, among other things, to recover on behalf of the Funds all allegedly excessive advisory fees received by defendants in the twelve month period preceding the start of each lawsuit, along with purported lost investment returns on those amounts, plus interest. ~~On March 25, 2015, defendants’ motion to dismiss the Consolidated Complaint was denied.~~ The defendants believe the claims in both lawsuits are without merit and ~~intend~~are vigorously defending the actions. On September 25, 2017, the defendants filed a motion for summary judgment to ~~vigorously defend~~dismiss the ~~actions.~~lawsuit, which is pending.

In November ~~12, 2015 and November 16,~~ 2015, BlackRock, Inc., BlackRock Realty Advisors, Inc. (“BRA”) ~~and~~, BlackRock US Core Property Fund, Inc. (formerly known as ~~the~~ BlackRock Granite Property Fund, Inc.) (“Granite Fund”), ~~along with~~and certain other Granite Fund related entities (collectively, the “BlackRock Parties”) were named as defendants in thirteen 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~~manages the Property, and certain other non-BlackRock related entities, including the developer of the Property, building contractors and building materials suppliers. The plaintiffs ~~allege,~~alleged, among other things, that the BlackRock Parties were negligent in their ownership, control and maintenance of the Property’s balcony, and ~~seek~~sought monetary, including punitive, damages. Additionally, on March 16, 2016, three former tenants of the Library Gardens apartment unit ~~that~~who were not physically injured but 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 unspecifiedParties for emotional ~~damage. Several defendants have also filed cross-complaints alleging a variety of claims, including claims against~~damages. In November 2017, the BlackRock Parties ~~for contribution, negligence,~~settled all of the lawsuits relating to Library Gardens and ~~declaratory relief. BlackRock believes~~ the ~~claims against the BlackRock Parties are without merit~~cases were formally dismissed in March and ~~intends to vigorously defend the actions.~~April 2018.

On June 16, 2016, iShares Trust, BlackRock, Inc. and certain of its advisory affiliates, and the directors and certain officers of the iShares ~~funds~~ETFs were named as defendants in a purported class action lawsuit filed in California state court. The lawsuit was filed by investors in certain iShares ~~funds~~ETFs (the ~~"Funds"~~"ETFs"), and alleges the defendants violated the federal securities laws, purportedly by failing to adequately disclose in prospectuses issued by the ~~Funds~~ETFs the risks to ~~Fund~~the ETFs’ shareholders in the event of a "flash crash." Plaintiffs seek unspecified monetary damages. The ~~Plaintiffs’~~plaintiffs’ complaint was dismissed in December 2016 and on January 6, 2017, plaintiffs filed an amended complaint. The defendants filed a motion for judgment on the pleadings dismissing that complaint. On ~~April 27,~~September 18, 2017, the court ~~granted~~dismissed the ~~defendants' motion in part and denied it in part. The defendants believe~~lawsuit. On December 1, 2017, the ~~claims in this lawsuit are without merit and intend to vigorously defend~~plaintiffs appealed the ~~action.~~dismissal of their lawsuit.

On April 5, 2017, BlackRock, Inc., BlackRock Institutional Trust Company, N.A. (“BTC”), the BlackRock, Inc. Retirement Committee and various sub-committees, and a BlackRock employee were named as defendants in a purported class action lawsuit brought in the U.S. District Court for the Northern District of California by a former employee on behalf of all BlackRock employee 401(k) Plan (the “Plan”) participants and beneficiaries in the Plan from April 5, 2011, to the present. The lawsuit generally alleges that the defendants breached their duties towards Plan participants in violation of the Employee Retirement Income Security Act of 1974 by, among other things, offering investment options that were overly expensive, underperformed peer funds, focused disproportionately on active versus passive strategies, and were unduly concentrated with investment options managed by BlackRock. While the complaint does not contain any

specific amount in alleged damages, it claims that the purported underperformance and hidden fees cost Plan participants more than $60 million. On October 10, 2017, the plaintiffs filed an Amended Complaint, which, among other things, adds as defendants certain current and former members of the BlackRock Retirement and Investment Committees. The Amended Complaint also includes a new purported class claim on behalf of investors in certain Collective Trust Funds (“CTFs”) managed by BTC. Specifically, the plaintiffs allege that BTC, as fiduciary to the CTFs, engaged in self-dealing by, most significantly, selecting itself as the lending agent on terms that plaintiffs claim were excessive. The defendants believe the claims in this lawsuit are without merit and ~~intend~~are vigorously defending the action. BlackRock moved to ~~vigorously defend~~dismiss the ~~action.~~Amended Complaint on November 8, 2017.

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 March 31, ~~2017,~~2018, the Company indemnified certain of its clients for their securities lending loan balances of approximately ~~$187.8~~$219 billion. The Company held, as agent, cash and securities totaling ~~$200.6~~$232 billion as collateral for indemnified securities on loan at March 31, ~~2017.~~2018. The fair value of these indemnifications was not material at March 31, ~~2017.~~2018.

See Non-GAAP Financial Measures for further information on as adjusted items and the reconciliation to accounting principles generally accepted in the United States (“GAAP“).

For further discussion of BlackRock’s revenue, expense, nonoperating results and income tax expense, see Discussion of Financial Results herein.

BlackRock reports its financial results in accordance with GAAP; however, management believes evaluating the Company’s ongoing operating results may be enhanced if investors have additional non-GAAP financial measures. Management reviews non-GAAP financial measures to assess ongoing operations and ~~for the reasons described below,~~ considers them to be ~~effective indicators,~~helpful, for both management and investors, ofin evaluating BlackRock’s financial performance over time. Management also uses non-GAAP financial measures as a benchmark to compare its performance with other companies and to enhance the comparability of this information for the reporting periods presented. Non-GAAP measures may pose limitations because they do not include all of BlackRock’s revenue and expense. BlackRock’s management does not advocate that investors consider such non-GAAP financial measures in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Non-GAAP measures may not be comparable to other similarly titled measures of other companies.

Management uses both GAAP and non-GAAP financial measures in evaluating BlackRock’s financial performance. Adjustments to GAAP financial measures (“non-GAAP adjustments”) include certain items management deems nonrecurring or that occur infrequently, transactions that ultimately will not impact BlackRock’s book value or certain tax items that do not impact cash flow.

Computations for all periods are derived from the condensed consolidated statements of income as follows:

Management believes operating income, as adjusted, and operating margin, as adjusted, are effective indicators of BlackRock’s financial performance over time and, therefore, provide useful disclosure to investors.

Revenue used for operating margin, as adjusted, excludes distribution and servicing costs paid to ~~related parties and other~~ third parties. Management believes such costs represent a benchmark for the amount of revenue passed through to external parties who distribute the Company’s products. In addition, management believes the exclusion of such costs is useful because it creates consistency in the treatment for certain contracts for similar services, which due to the terms of the contracts, are accounted for under GAAP on a net basis within investment advisory, administration fees and securities lending revenue. Amortization of deferred sales commissions is excludedBlackRock excludes from revenue used for operating margin, ~~measurement,~~ as adjusted, ~~because~~the costs related to distribution and servicing costs as a proxy for such ~~costs, over time, substantially offset distribution fee revenue the~~offsetting revenue.

Management believes net income attributable to BlackRock, Inc., as adjusted, and diluted earnings per common share, as adjusted, are useful measures of BlackRock’s profitability and financial performance. Net income attributable to BlackRock, Inc., as adjusted, equals net income attributable to BlackRock, Inc., GAAP basis, adjusted for significant nonrecurring items and charges that ultimately will not impact BlackRock’s book ~~value or certain tax items that do not impact cash flow.~~

See aforementioned discussion regarding operating income, as adjusted, and operating margin, as adjusted, for information on the PNC LTIP funding ~~obligation and the restructuring charge.~~obligation.

For each period presented, the non-GAAP adjustment related to the ~~restructuring charge and~~ PNC LTIP funding obligation was tax effected at the respective blended rates applicable to the adjustments. Amounts for income tax matters represent net noncash (benefits) expense primarily associated with the revaluation of certain deferred tax liabilities related to intangible assets and goodwill. Amounts have been excluded from the as adjusted results as these items will not have a cash flow impact and to ensure comparability among periods presented.adjustment.

Per share amounts reflect net income attributable to BlackRock, Inc., as adjusted divided by diluted weighted average common shares outstanding.

(3) Nonvoting participating preferred stock is considered to be a common stock equivalent for purposes of determining basic and diluted earnings per share calculations.

AUM for reporting purposes generally is based upon how investment advisory and administration fees are calculated for each portfolio. Net asset values, total assets, committed assets or other measures may be used to determine portfolio AUM.

2017.The three months ended March 31, 2017 income tax expense (GAAP) included an $81 million discrete tax benefit ~~reflecting the adoption of new accounting guidance~~ related to stock-based compensation awards that vested in the first quarter of 2017. ~~See Note 2,~~ ~~Significant Accounting Policies, for further information.~~

~~2016.~~ The three months ended March 31, 2016 income tax expense (GAAP) included a $4 million net noncash tax benefit, primarily related to the revaluation of certain deferred income tax liabilities, including the effect of tax legislation enacted in Japan and domestic state and local tax changes, which has been excluded from as adjusted results.

The following table presents a reconciliation of the condensed consolidated statement of financial condition presented on a GAAP basis to the condensed consolidated statement of financial condition, excluding the impact of separate account assets and separate account collateral held under securities lending agreements (directly related to lending separate account securities) and separate account liabilities and separate account collateral liabilities under securities lending agreements and consolidated sponsored investment funds, including consolidated VIEs.

The Company presents the as adjusted balance sheet as additional information to enable investors to exclude certain assets that have equal and offsetting liabilities or noncontrolling interests that ultimately do not have an impact on stockholders’ equity or cash flows. Management views the as adjusted balance sheet, a non-GAAP financial measure, as an economic presentation of the Company’s total assets and liabilities; however, it does not advocate that investors consider such non-GAAP financial measures in isolation from, or as a substitute for, financial information prepared in accordance with GAAP.

Separate Account Assets and Liabilities and Separate Account Collateral Held under Securities Lending Agreements

Separate account assets are maintained by BlackRock Life Limited, a wholly owned subsidiary of the Company that 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 Company records equal and offsetting separate account liabilities. The separate account assets are not available to creditors of the Company and the holders of the pension contracts have no recourse to the Company’s assets. The net investment income attributable to separate account assets accrues directly to the contract owners and is not reported on the condensed consolidated statements of income. While BlackRock has no economic interest in these assets or liabilities, BlackRock earns an investment advisory fee for the service of managing these assets on behalf of its clients.

In addition, the Company records on its condensed consolidated statements of financial condition the separate account collateral received under BlackRock Life Limited securities lending arrangements as its own asset in addition to an equal and offsetting separate account collateral liability for the obligation to return the collateral. The collateral is not available to creditors of the Company, and the borrowers under the securities lending arrangements have no recourse to the Company’s assets.

The Company consolidates certain sponsored investment funds accounted for as voting rights entities (“VREs”) and VIEs, (collectively, “Consolidated Sponsored Investment Funds”). See Note 2, Significant Accounting Policies, in the notes to the consolidated financial statements contained in the ~~2016~~2017 Form 10-K for more information on the Company’s consolidation policy.

The Company cannot readily access cash and cash equivalents or other assets held by Consolidated Sponsored Investment Funds to use in its operating activities. In addition, the Company cannot readily sell investments held by Consolidated Sponsored Investment Funds in order to obtain cash for use in the Company’s operations.

Accounts payable and accrued liabilities at March 31, ~~2017~~2018 increased ~~$906~~$260 million from December 31, ~~2016~~2017 due to higher current income taxes payables and increased accruals.

Other liabilities increased $504 million from December 31, 2017, primarily related to higher unit trust payables (substantially offset by an increase in unit trust receivables recorded within ~~accounts receivable).~~other assets) and other operating liabilities.

~~Net deferred income tax liabilities at March 31, 2017 increased $190 million, primarily due to the effects of temporary differences associated with stock-based compensation.~~

The Company’s investments and investments of consolidated VIEs (collectively, “Total Investments”) were ~~$1,857~~$2,050 million and ~~$1,097~~$1,637 million, respectively, at March 31, ~~2017.~~2018. Total Investments include consolidated investments held by sponsored investment funds accounted for as VREs and VIEs. Management reviews BlackRock’s Total Investments on an “economic” basis, which eliminates the portion of Total Investments that does not impact BlackRock’s book value or net income attributable to BlackRock. BlackRock’s management does not advocate that investors consider such non-GAAP financial measures in isolation from, or as a substitute for, financial information prepared in accordance with GAAP.

The Company presents Total Investments, as adjusted, to enable investors to understand the portion of Total Investments that is owned by the Company, net of NCI, as a gauge to measure the impact of changes in net nonoperating income (expense) on investments to net income (loss) attributable to BlackRock.

The Company further presents net “economic” investment exposure, net of deferred compensation investments and hedged investments, to reflect another ~~gauge~~helpful measure for investors. The economic impact of Total Investments held pursuant to deferred compensation arrangements is offset by a change in compensation expense. The impact of certain investments is substantially mitigated by swap hedges. Carried interest capital allocations are excluded as there is no impact to BlackRock’s stockholders’ equity until such amounts are realized as performance fees. Finally, the Company’s regulatory investment in Federal Reserve Bank stock, which is not subject to market or interest rate risk, is excluded from the Company’s net economic investment exposure.

BlackRock Cash Flows Excluding the Impact of Consolidated Sponsored Investment Funds

The condensed consolidated statements of cash flows include the cash flows of the Consolidated Sponsored Investment Funds. The Company uses an adjusted cash flow statement, which excludes the impact of Consolidated Sponsored Investment Funds, as a supplemental non-GAAP measure to assess liquidity and capital requirements. The Company believes that its cash flows, excluding the impact of the Consolidated Sponsored Investment Funds, provide investors with useful information on the cash flows of BlackRock relating to its ability to fund additional operating, investing and financing activities. BlackRock’s management does not advocate that investors consider such non-GAAP measures in isolation from, or as a substitute for, its cash flows presented in accordance with GAAP.

The following table presents a reconciliation of the condensed consolidated statements of cash flows presented on a GAAP basis to the condensed consolidated statements of cash flows, excluding the impact of the cash flows of Consolidated Sponsored InvestmentFunds:

Sources of BlackRock’s operating cash primarily include investment advisory, administration fees and securities lending revenue, performance fees, revenue from technology and risk management services, advisory and other revenue and distribution fees. BlackRock uses its cash to pay all operating expense, interest and principal on borrowings, income taxes, dividends on BlackRock’s capital stock, repurchases of the Company’s stock, capital expenditures and purchases of co-investments and seed investments.

For details of the Company’s GAAP cash flows from operating, investing and financing activities, see the Condensed Consolidated Statements of Cash Flows contained in Part I, Item 1 of this filing.

Cash flows from operating activities, excluding the impact of Consolidated Sponsored Investment Funds, primarily include the receipt of investment advisory and administration fees, securities lending revenue and performance fees offset by the payment of operating expenses incurred in the normal course of business, including year-end incentive compensation accrued for in the prior year.

Total liquidity resources decreased ~~$465~~$897 million during the three months ended March 31, ~~2017,~~2018, primarily reflecting cash payments of ~~2016~~2017 year-end incentive awards, share repurchases of ~~$562~~$719 million and cash dividend payments of ~~$447~~$505 million, partially offset by ~~$697 million of proceeds from issuance of long-term borrowings and~~ cash flows from other operating activities.

A significant portion of the Company’s ~~$2,727~~$3,163 million of Total Investments, as adjusted, is illiquid in nature and, as such, cannot be readily convertible to cash.

Share Repurchases. In January 2017, the Board of Directors approved an increase in the shares that may be repurchased under the Company’s existing share repurchase program to allow for the repurchase of an additional 6 million shares for a total up to 9 million shares of BlackRock common stock.

The Company repurchased ~~0.7~~0.6 million common shares in open market transactions under the share repurchase program for approximately ~~$275~~$335 million during the three months ended March 31, ~~2017.~~2018. At March 31, ~~2017,~~2018, there were ~~8.3~~5.8 million shares still authorized to be repurchased.

Net Capital Requirements. The Company is required to maintain net capital in certain regulated subsidiaries within a number of jurisdictions, which is partially maintained by retaining cash and cash equivalent investments in those subsidiaries or jurisdictions. As a result, such subsidiaries of the Company may be restricted in their ability to transfer cash between different jurisdictions and to their parents. Additionally, transfers of cash between international jurisdictions ~~including repatriation to the United States,~~ may have adverse tax consequences that could discourage such transfers.

BlackRock Institutional Trust Company, N.A. (“BTC”) is chartered as a national bank that does not accept client deposits and whose powers are limited to trust and other fiduciary activities. BTC provides investment management services, including investment advisory and securities lending agency services, to institutional ~~investors and other~~ clients. BTC is subject to regulatory capital and liquid asset requirements administered by the Office of the Comptroller of the Currency.

At March 31, ~~2017~~2018 and December 31, ~~2016,~~2017, the Company was required to maintain approximately ~~$1.7~~$2.1 billion and ~~$1.4~~$1.8 billion, respectively, in net capital in certain regulated subsidiaries, including BTC, entities regulated by the Financial Conduct Authority and Prudential Regulation Authority in the United Kingdom, and the Company’s broker-dealers. The Company was in compliance with all applicable regulatory net capital requirements.

At March 31, ~~2017,~~2018, the principal amount of long-term borrowings outstanding was ~~$5.6~~$5.1 billion. See Note 12, Borrowings, in the ~~2016~~2017 Form 10-K for more information on borrowings outstanding as of December 31, ~~2016.~~

In March 2017, the Company issued $700 million in aggregate principal amount of 3.20% senior unsecured and unsubordinated notes maturing on March 15, 2027 (the “2027 Notes”). The net proceeds of the 2027 Notes were used towards the redemption of 6.25% notes in April 2017. Interest is payable semi-annually on March 15 and September 15 of each year, commencing September 15, 2017, and is approximately $22 million per year. The 2027 Notes may be redeemed prior to maturity at any time in whole or in part at the option of the Company at a “make-whole” redemption price. The unamortized discount and debt issuance costs are being amortized over the remaining term of the 2027 Notes.

During the three months ended March 31, ~~2017,~~2018, the Company paid approximately ~~$39~~$29 million of interest on long-term borrowings. Future principal repayments and interest requirements at March 31, ~~2017~~2018 were as follows:

Acquisition. In November 2017, the Company announced that it had entered an agreement to acquire the asset management business of Citibanamex, a subsidiary of Citigroup Inc. The transaction is expected to close in the second half of 2018, subject to customary regulatory approvals and closing conditions. Consideration for the transaction will include an upfront cash payment of $350 million and contingent consideration.

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 March 31 ~~2017~~2018 totaled ~~$113~~$242 million, and is included in other liabilities on the condensed consolidated ~~statement~~statements of financial condition.

Carried Interest Clawback. As a general partner in certain investment funds, including private equity partnerships and certain hedge funds, the Company may receive carried interest cash distributions from the partnerships in accordance with distribution provisions of the partnership agreements. The Company may, from time to time, be required to return all or a portion of such distributions to the limited partners in the event the limited partners do not achieve a return as specified in the various partnership agreements. Therefore, BlackRock records carried interest subject to such clawback provisions in Total Investments, or cash/cash of consolidated VIEs to the extent that it is distributed, and as a deferred carried interest liability/other liabilities of consolidated VIEs on its condensed consolidated statements of financial condition. Carried interest is recorded as performance fees on BlackRock’s condensed consolidated statements of income ~~upon the earlier of the termination of the investment fund or~~ when the ~~likelihood~~fees are no longer probable of ~~clawback is considered mathematically improbable.~~significant reversal.

Indemnifications. On behalf of certain clients, the Company lends securities to highly rated banks and broker-dealers. In these securities lending transactions, the borrower is required to provide and maintain collateral at or above regulatory minimums. Securities on loan are marked to market daily to determine if the borrower is required to pledge additional collateral. 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 March 31 ~~2017,~~2018, the Company indemnified certain of its clients for their securities lending loan balances of approximately ~~$187.8~~$219 billion. The Company held, as agent, cash and securities totaling ~~$200.6~~$232 billion as collateral for indemnified securities on loan at March 31, ~~2017.~~2018. The fair value of these indemnifications was not material at March 31, ~~2017.~~2018.

While the collateral pledged by a borrower is intended to be sufficient to offset the borrower’s obligations to return securities borrowed and any other amounts owing to the lender under the relevant securities lending agreement, in the event of a borrower default, the Company can give no assurance that the collateral pledged by the borrower will be sufficient to fulfill such obligations. If the amount of such pledged collateral is not sufficient to fulfill such obligations to a client for whom the Company has provided indemnification, BlackRock would be responsible for the amount of the shortfall. These indemnifications cover only the collateral shortfall described above, and do not in any way guarantee, assume or otherwise insure the investment performance or return of any cash collateral vehicle into which securities lending cash collateral is invested.

The preparation of condensed consolidated 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 condensed consolidated financial statements and the reported amounts of revenue and expense during the reporting periods. Actual results could differ significantly from those estimates. Management considers the following critical accounting policies important to understanding the condensed consolidated financial statements. For a summary of these and additional accounting policies see Note 2, Significant Accounting Policies, in the condensed consolidated financial statements ~~contained in Part I, Item 1 of this filing~~ and Critical Accounting Policies in Management’s Discussion and Analysis of Financial Condition and Results of Operations ~~in the 2016 Form 10-K~~ and Note 2, Significant Accounting Policies, in the ~~2016~~2017 Form 10-K for further information.

Consolidation. In the normal course of business, the Company is the manager of various types of sponsored investment vehicles. The Company performs an analysis for investment products to determine if the product is a VIE or a VRE. Assessing whether an entity is a VIE or a VRE involves judgment and analysis. Factors considered in this assessment include the entity’s legal organization, the entity’s capital structure and equity ownership, and any related party or de facto agent implications of the Company’s involvement with the entity. Investments that are determined to be VREs are consolidated if the Company can exert control over the financial and operating policies of the investee, which generally exists if there is greater than 50% voting interest. See Note 4,5, Consolidated Voting Rights Entities, in the notes to the condensed consolidated financial statements for more information. Investments that are determined to be VIEs are consolidated if the Company is the primary beneficiary (“PB”) of the entity.

At March 31, ~~2017,~~2018, BlackRock was determined to be the PB for certain investment funds that were determined to be VIEs, which required BlackRock to consolidate them. BlackRock was deemed to be the PB because it has the power to direct the activities that most significantly impact the entities’ economic performance and has the obligation to absorb losses or the right to receive benefits that potentially could be significant to the VIE. The Company generally consolidates VIEs in which it holds an equity ownership interest of 10% or greater and deconsolidates such VIEs once equity ownership falls below 10%. See Note 5,6, Variable Interest Entities, in the notes to the condensed consolidated financial statements ~~contained in the Part 1, Item 1 of this filing~~ for more information.

Fair Value Measurements. The Company’s assessment of the significance of a particular input to the fair value measurement according to the fair value hierarchy (i.e., Level 1, 2 and 3 inputs, as defined) in its entirety requires judgment and considers factors specific to the financial instrument. See Note 2, Significant Accounting Policies, in the condensed consolidated financial statements ~~contained in Part I, Item 1 of this filing~~ for more information on fair value measurements.

Revenue Recognition. Revenue is recognized upon transfer of control of promised services to customers in an amount that reflects consideration to which the Company expects to be entitled in exchange for those services (the “transaction price”). 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 as part of its transaction price 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. Management judgment may be required when determining the following: whether services are considered distinct and should be accounted for separately; when variable consideration is no longer probable of significant reversal (and hence can be included in the transaction price); whether certain revenue should be presented gross or net of certain related costs; when a promised service transfers to the customer; and the applicable method of measuring progress for services transferred to the customer over time.

Investment ~~Advisory Performance Fees / Carried Interest.~~advisory and administration fees are recognized as the services are performed over time. Such fees are primarily based on agreed-upon percentages of net asset value, AUM or committed capital. These 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 fees waived pursuant to contractual expense limitations of the funds or voluntary 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 advisors on a gross basis in the condensed consolidated statements of income where it is deemed to be the principal.

The Company earns revenue by lending securities on behalf of clients, primarily to highly rated banks and broker-dealers. Revenue is recognized over time as services are performed. The securities loaned are secured by collateral, generally ranging from 102% to 112% of the value of the loaned securities. 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 the three months ended March 31, 2018 and 2017, securities lending revenue earned by the Company totaled $155 million and $141 million, respectively, and is recorded in investment advisory, administration fees and securities lending revenue on the condensed consolidated statements of income.

The Company receives investment advisory performance fees, orincluding 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. Such fees are recorded upon completion of the measurement period,~~thresholds, which ~~varies~~may vary by product or account, and ~~could be~~include monthly, quarterly, annually or ~~longer.~~longer measurement periods. 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.

~~In addition, the~~The Company is allocated carried interest from certain alternative investment products upon exceeding performance thresholds. BlackRock may be required to reverse/return all, or part, of such carried interest allocations depending upon future performance of these funds. Therefore, ~~BlackRock records~~ carried interest subject to such clawback provisions is recorded in ~~Total Investments,~~investments/investments of consolidated VIEs or cash/cash of consolidated VIEs to the extent that it is distributed, on its condensed consolidated statements of financial condition. ~~Carried~~

Performance fees, including carried interest, are recognized when it is ~~recorded~~determined that they are no longer probable of significant reversal (such as ~~performance fee revenue~~ upon the ~~earlier~~sale of ~~the termination of the~~a fund’s investment ~~fund~~ or when the ~~likelihood~~amount of ~~clawback~~AUM becomes known as of the end of a specified measurement period). Significant judgement is ~~considered mathematically improbable.~~involved in making such determination. At each reporting date, the Company considers various factors in estimating performance fees to be recognized, including carried interest. These factors include but are not limited to whether: (1) the fees are dependent on the market and thus are highly susceptible to factors outside the Company’s influence; (2) the fees have a large number and a broad

range of possible amounts; and (3) the funds or separately managed accounts have the ability to invest or reinvest its sales proceeds.

The Company records a contract liability for deferred carried interest ~~liability~~ to the extent it receives cash or capital allocations related to carried interest prior to meeting the revenue recognition criteria. At March 31, ~~2017~~2018 and December 31, ~~2016,~~2017, the Company had ~~$151~~$224 million and ~~$152~~$219 million, respectively, of deferred carried interest recorded in other liabilities/other liabilities of consolidated VIEs on the condensed consolidated statements of financial condition. A portion of the deferred carried interest ~~liability will~~may also be paid to certain employees. The ultimate timing of the recognition of performance fee revenue and related compensation expense, if any, for these products is unknown.

~~The following table presents~~ For the three months ended March 31, 2018 and 2017, performance fee revenue (which included recognized carried interest) both totaled $70 million. See Note 13, Revenue, in the notes to the condensed consolidated financial statements for detailed changes in the deferred carried interest liability ~~(including the portion related to consolidated VIEs)~~balance for the three months ended March 31, 2018 and 2017.

Fees earned for technology and risk management revenue are recorded as services are performed and are generally determined using the value of positions on the Aladdin platform or on a fixed-rate basis. For the three months ended March 31, 2018 and 2017, technology and ~~2016:~~risk management revenue totaled $184 million and $154 million, respectively.

Adjustments to revenue arising from initial estimates recorded historically have been immaterial since the majority of BlackRock’s investment advisory and administration revenue is calculated based on AUM and since the Company does not record performance fee revenue until: (1) performance thresholds have been exceeded and (2) management determines the fees are no longer probable of significant reversal.

The Company accounts for fund distribution services and shareholder servicing as distinct services, separate from fund management services, because customers can benefit from each of the services on their own and because the services are separately identifiable (that is, the nature of the promised services is to transfer each service individually). The Company records upfront and ongoing sales commissions as distribution fee revenue for serving as the principal underwriter and/or distributor for certain mutual funds that it manages. The Company recognizes the upfront fees for front-end load funds on a trade date basis, when the services are performed and the amount the Company is entitled to is known. The on-going distribution fees are generally based on net asset values and are recognized when the amount is known. Distribution services are satisfied at a point in time. Consequently, a portion of the on-going distribution fees the Company recognized may be related to the services performed in prior periods that met the recognition criteria in the current period. The Company recognizes ongoing shareholder servicing fee revenue when and as shareholder services are performed over time. The Company contracts with third parties for various fund distribution services and shareholder servicing of certain funds to be performed on its behalf. These arrangements are generally priced as a portion of the fee paid to the Company by the fund or as an agreed-upon percentage of net asset value. The Company presents its distribution fees and distribution and servicing costs incurred on a gross basis in the condensed consolidated statements of income as it is deemed to be the principal in such transactions.

For accounting pronouncements that the Company adopted during the three months ended March 31, ~~2017~~2018 and for recent accounting pronouncements not yet adopted, see Note 2, Significant Accounting Policies, in the condensed consolidated financial ~~statements contained in Part I, Items 1 of this filing.~~statements.

AUM Market Price Risk. BlackRock’s investment advisory and administration fees are primarily comprised of fees based on a percentage of the value of AUM and, in some cases, performance fees expressed as a percentage of the returns realized on AUM. At March 31, ~~2017,~~2018, the majority of the Company’s investment advisory and administration fees were based on average or period end AUM of the applicable investment funds or separate accounts. Movements in equity market prices, interest rates/credit spreads, foreign exchange rates or all three could cause the value of AUM to decline, which would result in lower investment advisory and administration fees.

Corporate Investments Portfolio Risks. As a leading investment management firm, BlackRock devotes significant resources across all of its operations to identifying, measuring, monitoring, managing and analyzing market and operating risks, including the management and oversight of its own investment portfolio. The Board of Directors of the Company has adopted guidelines for the review of investments to be made by the Company, requiring, among other things, that investments be reviewed by certain senior officers of the Company, and that certain investments may be referred to the Audit Committee or the Board of Directors, depending on the circumstances, for approval.

In the normal course of its business, BlackRock is exposed to equity market price risk, interest rate/credit spread risk and foreign exchange rate risk associated with its corporate investments.

BlackRock has investments primarily in sponsored investment products that invest in a variety of asset classes, including real assets, private equity and hedge funds. Investments generally are made for co-investment purposes, to establish a performance track record, to hedge exposure to certain deferred compensation plans or for regulatory purposes. Currently, the Company has a seed capital hedging program in which it enters into swaps to hedge market and interest rate exposure to certain investments. At March 31, ~~2017,~~2018, the Company had outstanding total return ~~swaps and interest rate~~ swaps with an aggregate notional value of approximately ~~$698 million and $41 million, respectively.~~$546 million. At March 31, 2018, there were no outstanding interest rate swaps.

At March 31, ~~2017,~~2018, approximately ~~$1.8~~$2.2 billion of BlackRock’s Total Investments were maintained in consolidated sponsored investment funds accounted for as VREs and VIEs. Excluding the impact of the Federal Reserve Bank stock, carried interest, investments made to hedge exposure to certain deferred compensation plans and certain investments that are hedged via the seed capital hedging program, the Company’s economic exposure to its investment portfolio is ~~$1,712~~$2,187 million. See Balance Sheet Overview- Investments and Investments of Consolidated VIEs in Management’s Discussion and Analysis of Financial Condition and Results of Operations for further information on the Company’s Total Investments.

Equity Market Price Risk. At March 31, ~~2017,~~2018, the Company’s net exposure to equity market price risk in its investment portfolio was approximately ~~$486~~$1,078 million of the Company’s total economic investment exposure. Investments subject to market price risk include private equity and real assets investments, hedge funds and funds of funds as well as mutual funds. The Company estimates that a hypothetical 10% adverse change in market prices would result in a decrease of approximately ~~$48.6~~$107.8 million in the carrying value of such investments.

Interest Rate/Credit Spread Risk. At March 31, ~~2017,~~2018, the Company was exposed to interest-rate risk and credit spread risk as a result of approximately ~~$1,226~~$1,109 million of Total Investments in debt securities and sponsored investment products that invest primarily in debt securities. Management considered a hypothetical 100 basis point fluctuation in interest rates or credit spreads and estimates that the impact of such a fluctuation on these investments, in the aggregate, would result in a decrease, or increase, of approximately ~~$28.1~~$23.9 million in the carrying value of such investments.

Foreign Exchange Rate Risk. As discussed above, the Company invests in sponsored investment products that invest in a variety of asset classes. The carrying value of the total economic investment exposure denominated in foreign currencies, primarily the British pound and Euro, was ~~$327~~$968 million at March 31, ~~2017.~~2018. A 10% adverse change in the applicable foreign exchange rates would result in approximately a ~~$32.7~~$96.8 million decline in the carrying value of such investments.

Other Market Risks. The Company executes forward foreign currency exchange contracts to mitigate the risk of certain foreign exchange risk movements. At March 31, ~~2017,~~2018, the Company had outstanding forward foreign currency exchange contracts with an aggregate notional value of approximately ~~$728 million.~~$1.5 billion.

Disclosure Controls and Procedures. Under the direction of BlackRock’s Chief Executive Officer and Chief Financial Officer, BlackRock evaluated the effectiveness of its disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this quarterly report on Form 10-Q. Based on this evaluation, BlackRock’s Chief Executive Officer and Chief Financial Officer have concluded that BlackRock’s disclosure controls and procedures were effective.

Internal Control over Financial Reporting. There were no changes in our internal control over financial reporting that occurred during the quarter ended March 31, ~~2017~~2018 that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.

From time to time, BlackRock receives subpoenas or other requests for information from various U.S. federal, state governmental and ~~domestic~~regulatory authorities 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~~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 under the caption In re BlackRock Mutual Funds Advisory Fee Litigation. The Consolidated Complaint, which purports to be brought derivatively on behalf of the Funds, alleges that the defendants violated Section 36(b) of the Investment Company Act by receiving allegedly excessive investment advisory fees from the Funds. On February 24, 2015, the same plaintiffs filed another complaint in the same court against BlackRock Investment Management, LLC and BlackRock Advisors, LLC. The allegations and legal claims in both complaints are substantially similar, with the new complaint purporting to challenge fees received by defendants after the plaintiffs filed their prior complaint. Both complaints seek, among other things, to recover on behalf of the Funds all allegedly excessive advisory fees received by defendants in the twelve month period preceding the start of each lawsuit, along with purported lost investment returns on those amounts, plus interest. ~~On March 25, 2015, defendants’ motion to dismiss the Consolidated Complaint was denied.~~ The defendants believe the claims in both lawsuits are without merit and ~~intend~~are vigorously defending the actions. On September 25, 2017, the defendants filed a motion for summary judgment to ~~vigorously defend~~dismiss the ~~actions.~~lawsuit, which is pending.

present. The lawsuit generally alleges that the defendants breached their duties towards Plan participants in violation of the Employee Retirement Income Security Act of 1974 by, among other things, offering investment options that were overly expensive, underperformed peer funds, focused disproportionately on active versus passive strategies, and were unduly concentrated with investment options managed by BlackRock. While the complaint does not contain any specific amount in alleged damages, it claims that the purported underperformance and hidden fees cost Plan participants more than $60 million. On October 10, 2017, the plaintiffs filed an Amended

Complaint, which, among other things, adds as defendants certain current and former members of the BlackRock Retirement and Investment Committees. The Amended Complaint also includes a new purported class claim on behalf of investors in certain Collective Trust Funds (“CTFs”) managed by BTC. Specifically, the plaintiffs allege that BTC, as fiduciary to the CTFs, engaged in self-dealing by, most significantly, selecting itself as the lending agent on terms that plaintiffs claim were excessive. The defendants believe the claims in this lawsuit are without merit and ~~intend~~are vigorously defending the action. BlackRock moved to ~~vigorously defend~~dismiss the ~~action.~~Amended Complaint on November 8, 2017.

During the three months ended March 31, ~~2017,~~2018, the Company made the following purchases of its common stock, which is registered pursuant to Section 12(b) of the Exchange Act.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
