iCRMH0921U/S-1830242-1/15• 1 Market Review* • Stock indexes rally in August : Global stocks posted their seventh consecutive monthly gain during August, led higher by Chinese equities despite growing regulatory concerns within the country and increasing signs of below average economic growth. U.S. and Japanese equities advanced the most among developed markets (U.S. stocks were buoyed by stronger than expected manufacturing and industrial data), while European stocks posted solid, but less substantial gains. Emerging market stocks also rose in August, despite continuing to underperform developed market stocks on a YTD basis due to challenges pertaining to COVID-19. • U.S. large-cap stocks continued to outperform small caps: Although it was a solid month for both U.S. large-cap stocks, as represented by the S&P 500, and small-cap stocks, as represented by the Russell 2000 Index, August marked the sixth consecutive month that U.S. large-cap stocks outperformed small-caps. In terms of style preference, large-cap growth stocks, as represented by the S&P Growth Index (+4.2%), substantially outperformed large-cap value stocks, as represented by the S&P 500 Value Index (+1.7%), continuing a broader trend that began back in April. Taken in combination, we suspect investors’ preference for larger-cap, growth-oriented names may reflect a shifting preference for companies that exhibit greater earnings consistency as the current economic cycle matures. • Bond indexes generally declined in August: Most bond indexes fell during the month, with the exception of higher risk sectors within the asset class, such as U.S. high yield and emerging market sovereigns. Higher quality fixed income sectors, such as U.S. Treasuries, municipals, and U.S. investment grade bonds fell in August, as investors were willing to tolerate higher levels of risk in pursuit of higher potential returns. Developed market international bond markets were particularly poor performers during the month, weighed down by an appreciating U.S. dollar. Market Scoreboard

Outlook & Positioning* • Remain overweight equities, but we have lowered beta recently: Despite ongoing risks posed by the contagiousness of the delta variant, we believe that U.S. economic growth should remain above-trend. Supported by historically strong labor markets and household wealth, coupled with the prospect of additional fiscal stimulus, we continue to have a more favorable view on the outlook for stocks than we do for either bonds or cash. Having said that, we have modestly reduced our equity overweights across most of our portfolios over the past month, as the confluence of seasonal factors, anticipation of likely adjustments to Federal Reserve policy later this year, and risks posed by upcoming U.S. debt-ceiling negotiations could cause equity volatility to increase from their year-to- date lows. • Emphasizing the quality factor while underweight defensive sectors: Because we believe economic growth will remain above its historical averages, particularly in the U.S. and in Europe, we continue to favor a barbell approach. This entails maintaining an overweight to secular growth stocks, such as Technology, Healthcare, and parts of Consumer Discretionary, while simultaneously remaining overweight the market’s more cyclically oriented sectors, such as Materials, Industrials and Energy. In both areas, we continue to focus on the quality factor, defined by high gross profitability, high earnings consistency, and manageable debt. Although we remain overweight Europe, we have recently begun the process of reducing our equity overweight to the region, in part, to begin placing greater emphasis on the U.S. quality factor. In addition, we have also reduced some of our equity overweight to China in recognition of the elevated regulatory risk relative to other regions. Lastly, we continue to remain underweight the market’s more “defensively” oriented sectors, including Consumer Staples and REITs, which we think may lag over the intermediate-term if economic growth remains vibrant. • Underweight duration within fixed income across our portfolios: August was the first month since April where high quality bonds - particularly long-dated U.S. Treasuries - declined in price. We believe that above average U.S. economic growth is likely to cause U.S. real interest rates to continue to follow a modestly upward trajectory. As a result, we prefer to remain underweight fixed income generally, but are particularly underweight the sector’s higher quality, duration sensitive segments, such as government bonds, agency mortgages, and investment grade bonds. Our preference is to hold less duration sensitive assets, such as high yield, bank loans, and emerging market debt. * Source: BlackRock views and Bloomberg as of date: August 31, 2021.

Gross performance does not reflect the deduction of any fees or expenses that may be charged by the financial professional. The fees and expenses that a client may incur in their account will reduce the account’s return. Net performance figures reflect the deduction of a hypothetical annual investment advisory fee of 3%, deducted monthly, that may be charged by the financial professional but do not reflect the deduction of any applicable custodial fees, platform fees or brokerage commissions.

iCRMH0921U/S-1830242-4/15 GA Selects Tax-Aware Model Portfolios BlackRock 20/80 Global Allocation (GA) Selects Tax-Aware Model Portfolio† Monthly Activity as of August 31, 2021 • Overweight equities: The 20/80 tax aware portfolio’s equity weighting decreased to 24% from 25% in August but remains overweight its benchmark**. Despite ongoing risks posed by the contagiousness of the delta variant, we believe that U.S. economic growth should remain above-trend. Supported by historically strong labor markets and household wealth, coupled with the prospect of additional fiscal stimulus, we continue to have a more favorable view on the outlook for stocks than we do for either bonds or cash. As a result, we are comfortable remaining overweight equities within the 20/80 tax aware portfolio, with a roughly equal emphasis across many of the market’s more economically “cyclical” sectors and its longer-term “secular growth” sectors.

• Decrease in aggregate stock weighting: We made few adjustments within the 20/80 tax aware portfolio’s equity allocation during August. One refinement was to increase the portfolio’s exposure to the U.S. quality factor at the expense of European equities. Our objective with these changes was to increase the portfolio’s exposure to those companies that tend to have higher levels of profitability and earnings consistency. At this point in the market cycle, it is our view that investors are likely to place a premium on the ‘steadiness’ and ‘durability’ of corporate earnings, rather than exhibit a strong preference for either the ‘growth’ or ‘value’ styles. European equity markets tend to have a greater level of cyclical exposure than their U.S. counterparts. The cumulative effect of these adjustments resulted in a decrease to the portfolio’s allocation to non-U.S. developed market stocks.

• Increased exposure to bonds: The 20/80 tax aware portfolio’s fixed income weighting increased to 73% from 72% in August and remains materially underweight its benchmark, both in terms of its overall bond exposure and its duration. During the month, we increased exposure to intermediate-term municipal bonds, while simultaneously reducing exposure to short-term municipal bonds. Modest additions to, and adjustments within, our team-affiliated fixed income mutual funds resulted in a modest increase in the portfolio’s overall exposure to securitized assets and a decrease in exposure to developed market non-U.S. government bonds. As a result of these changes, the portfolio’s duration increased slightly during the month to 3.3 years from 3.2 years, but remains well below the benchmark’s duration of 5.2 years.

Past performance does not guarantee future results. For standardized performance of the underlying funds within the model portfolios, please see the end of this document. Index performance is for illustrative purposes only. Index performance does not reflect any management fees, transaction costs or expenses. Indexes are unmanaged and one cannot invest directly in an index. Performance is annualized for time periods greater than 1 year. The performance shown does not reflect the performance of actual client accounts. Each model portfolio includes allocations to underlying constituent securities and uses the underlying securities’ historical performance. Where the constituent security is a fund, performance (i) assumes reinvestment of dividends and capital gains, (ii) reflects the deduction of fund expenses, including management fees and other expenses, and (iii) does not reflect any applicable sales charges. The performance of actual client accounts may differ from the performance shown for a variety of reasons, including but not limited to: the financial professional is responsible for implementing trades in the accounts; differences in market conditions; client-imposed investment restrictions; the timing of client investments and withdrawals; feespayable by such accounts; and/or other factors.

Gross performance does not reflect the deduction of any fees or expenses that may be charged by the financial professional. The fees and expenses that a client may incur in their account will reduce the account’s return. Net performance figures reflect the deduction of a hypothetical annual investment advisory fee of 3%, deducted monthly, that may be charged by the financial professional but do not reflect the deduction of any applicable custodial fees, platform fees or brokerage commissions. Due to the compounding effect of these fees, annual net performance results may be lower than stated gross returns less the stated hypothetical annual fee. Actual advisory fees charged by an account’s financial professional may vary. • 10

iCRMH0921U/S-1830242-10/15 GA Selects Tax-Aware Model Portfolios BlackRock 80/20 Global Allocation (GA) Selects Tax-Aware Model Portfolio† Monthly Activity as of August 31, 2021 • Overweight equities: The 80/20 tax-aware portfolio’s equity weighting decreased to 88% from 90% in August and remains overweight its benchmark**. Despite ongoing risks posed by the contagiousness of the delta variant, we believe that U.S. economic growth should remain above-trend. Supported by historically strong labor markets and household wealth, coupled with the prospect of additional fiscal stimulus, we continue to have a more favorable view on the outlook for stocks than we do for either bonds or cash. As a result, we are comfortable remaining overweight equities within the 80/20 tax-aware portfolio, with a roughly equal emphasis across many of the market’s more economically “cyclical” sectors and its longer-term “secular growth” sectors.

• Decrease in aggregate stock weighting: We made few adjustments within the 80/20 tax-aware portfolio’s equity allocation during August. One refinement was to increase the portfolio’s exposure to the U.S. quality factor at the expense of European equities. In addition, we added to our broader emerging market equity exposure, while simultaneously reducing some direct exposure to Chinese equities, due to rising concerns related to government regulation. Lastly, we trimmed some exposure to U.S. Materials stocks. Our objective with these changes was to increase the portfolio’s exposure to those companies that tend to have higher levels of profitability and earnings consistency. At this point in the market cycle, it is our view that investors are likely to place a premium on the ‘steadiness’ and ‘durability’ of corporate earnings, rather than exhibit a strong preference for either the ‘growth’ or ‘value’ styles. The cumulative effect of these adjustments resulted in a modest decrease to the portfolio’s allocation to non-U.S. developed market stocks.

• Increased exposure to bonds: The 80/20 tax-aware portfolio’s fixed income weighting increased to 9% from 8% in August and remains materially underweight its benchmark, both in terms of its overall bond exposure and its duration. During the month, we increased exposure to short-term U.S. municipals and also added fractionally to one of our team-affiliated mutual funds. The net result of these adjustments was to increase the portfolio’s overall exposure to municipals, while simultaneously reducing exposure to emerging market bonds. As a result of these changes, the portfolio’s duration incrementally increased to 0.2 years from 0.1 years, but remains well below the benchmark’s duration of 1.3 years.

This information should not be relied upon as investment advice, research, or a recommendation by BlackRock regarding (i) the funds, (ii) the use or suitability of the model portfolios or (iii) any security in particular. Only an investor and their financial professional know enough about their circumstances to make an investment decision. Carefully consider the investment objectives, risk factors, charges and expenses of funds within the model portfolios before investing. This and other information can be found in the funds’ prospectuses or, if available, the summary prospectuses which may be obtained by visiting each fund company's website or calling their toll-free number. For BlackRock and iShares Funds, please visit www..com or www.iShares.com. Investing involves risk, including possible loss of principal. Asset allocation and diversification may not protect against market risk, loss of principal or volatility of returns. Index performance is for illustrative purposes only. Index performance does not reflect any management fees, transaction costs or expenses. Indexes are unmanaged and one cannot invest directly in an index. Past performance does not guarantee future results. The BlackRock model portfolios are made available to financial professionals by BlackRock Fund Advisors (“BFA”) or BlackRock , LLC (“BIM”), which are registered investment advisers, or by BlackRock Investments, LLC (“BRIL”), which is the distributor of the BlackRock and iShares funds within the BlackRock model portfolios. BFA, BIM and BRIL (collectively, “BlackRock”) are affiliates. The BlackRock model portfolios are provided for illustrative and educational purposes only. The BlackRock model portfolios do not constitute research, are not personalized investment advice or an investment recommendation from BlackRock to any client of a third party financial professional, and are intended for use only by a third party financial professional, with other information, as a resource to help build a portfolio or as an input in the development of investment advice for its own clients. Such financial professionals are responsible for making their own independent judgment as to how to use the BlackRock model portfolios. BlackRock does not have investment discretion over, or place trade orders for, any portfolios or accounts derived from the BlackRock model portfolios. BlackRock is not responsible for determining the appropriateness or suitability of the BlackRock model portfolios, or any of the securities included therein, for any client of a financial professional. Information concerning the BlackRock model portfolios – including holdings, performance, and other characteristics – may vary materially from any portfolios or accounts derived from the BlackRock model portfolios. There is no guarantee that any investment strategy or model portfolio will be successful or achieve any particular level of results. The BlackRock model portfolios themselves are not funds. The BlackRock model portfolios include investments in shares of funds. Clients will indirectly bear fund expenses in respect of portfolio assets allocated to funds, in addition to any fees payable associated with any applicable advisory or wrap program. BlackRock intends to allocate all or a significant percentage of the BlackRock model portfolios to funds for which it and/or its affiliates serve as investment manager and/or are compensated for services provided to the funds ("BlackRock Affiliated Funds"). BlackRock has an incentive to (a) select BlackRock Affiliated Funds and (b) select BlackRock Affiliated Funds with higher fees over BlackRock Affiliated Funds with lower fees. The fees that BlackRock and its affiliates receive from investments in the BlackRock Affiliated Funds constitute BlackRock’s compensation with respect to the BlackRock model portfolios. This may result in BlackRock model portfolios that achieve a level of performance less favorable to the model portfolios, or reflect higher fees, than otherwise would be the case if BlackRock did not allocate to BlackRock Affiliated Funds. This material doesnot constitute any specific legal, tax or accounting advice. Please consult with qualified professionals for this type of advice. Fixed income risks include interest-rate and credit risk. Typically, when interest rates rise, there is a corresponding decline in bond values. Credit risk refers to the possibility that the bond issuer will not be able to make principal and interest payments. Non-investment-grade debt securities (high-yield/junk bonds) may be subject to greater market fluctuations, risk of default or loss of income and principal than higher-rated securities. Mortgage-backed securities ("MBS") and commercial mortgage-backed securities ("CMBS”) are subject to prepayment and extension risk and therefore react differently to changes in interest rates than other bonds. Small movements in interest rates may quickly and significantly reduce the value of certain mortgage-backed securities. There may be less information on the financial condition of municipal issuers than for public corporations. The market for municipal bonds may be less liquid than for taxable bonds. Some investors may be subject to federal or state income taxes or the Alternative Minimum Tax (AMT). Capital gains distributions, if any, are taxable. An investment in a treasury Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency and its return and yield will fluctuate with market conditions. International investing involves risks, including risks related to foreign currency, limited liquidity, less government regulation and the possibility of substantial volatility due to adverse political, economic or other developments. These risks often are heightened for investments in emerging/developing markets and in concentrations of single countries. Funds that concentrate investments in specific industries, sectors, markets or asset classes may underperform or be more volatile than other industries, sectors, markets or asset classes and the general securities market. A fund's use of derivatives may reduce a fund's returns and/or increase volatility and subject the fund to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation. A fund could suffer losses related to its derivative positions because of a possible lack of liquidity in the secondary market and as a result of unanticipated market movements, which losses are potentially unlimited. There can be no assurance that any fund’s hedging transactions will be effective. There can be no assurance that performance will be enhanced or risk will be reduced for funds that seek to provide exposure to certain quantitative investment characteristics ("factors"). Exposure to such investment factors may detract from performance in some market environments, perhaps for extended periods. In such circumstances, a fund may seek to maintain exposure to the targetedinvestment factors and not adjust to target different factors, which could result in losses. A fund's environmental, social and governance (“ESG”) investment strategy limits the types and number of investment opportunities available to the fund and, as a result, the fund may underperform other funds that do not have an ESG focus. A fund's ESG investment strategy may result in the fund investing in securities or industry sectors that underperform the market as a whole or underperform other funds screened for ESG standards. In addition, companies selected by the index provider may not exhibit positive or favorable ESG characteristics. Alternative investments present the opportunity for significant losses and some alternative investments have experienced periods of extreme volatility. Alternative investments may be less liquid than investments in traditional securities. Commodities' prices may be highly volatile. Prices may be affected by various economic, financial, social and political factors, which may be unpredictable and may have a significant impact on the prices of precious metals.
