An industry-first, tax-smart bond portfolio See how the Goldman Sachs Tax-Smart Bonds portfolio seeks to offer a strategy with potentially lower risk than investing in stocks, personalized by Betterment to be tax-smart to your financial situation. Key Takeaways: As interest rates eventually begin to drop, bonds may be a good way to earn extra after-tax yield compared to high-yield cash accounts in 2024 and beyond. For high-income investors in higher federal tax brackets (32% and above), certain bond strategies may offer tax advantages compared to high-yield cash accounts. The industry-first Goldman Sachs Tax-Smart Bonds portfolio is personalized by Betterment to your tax situation and seeks to provide a way for higher-income investors to get a tax-smart strategy with potentially lower risk than stock investing and is designed to increase after-tax yield. Over the past few years, investors have been able to put their cash to work in high-yield savings and cash accounts. In fact, the Fed has raised rates 11 times during its current cycle of interest rate hikes beginning in 2022. But those rate hikes have come to a pause. The last rate hike was in July 2023, and the world is waiting for the Fed to lower rates. So what does that mean for investors? Once the Fed lowers rates, those high-yield savings and cash accounts will follow suit, likely no longer offering the attractive 4% or even 5%-plus yields. The case for bonds in 2024 and beyond As interest rates begin to drop, bonds may be a good way to earn extra yield in 2024 and beyond. Investors looking to continue to earn yield should consider three points: Variable interest rates on high-yield cash accounts will likely fall when the Fed lowers rates, but bonds, on the other hand, tend to benefit from rate cuts because as yields fall, bond prices rise and generate return. Bonds, especially short-maturity bonds, can be a good choice to help preserve your money compared to stocks. For high earners, especially in the 32% or greater tax bracket, certain bonds may offer tax advantages compared to high-yield cash accounts. As the Fed reduces rates, bonds may be a wise alternative. Just a reminder, even short-term bond portfolios carry a bit more risk than cash management accounts, which are generally FDIC-insured and provide the stated yield. Bonds are securities that are exposed to market volatility but, in return, provide the opportunity to increase after-tax yield, which is the money you actually get to keep after paying taxes. Meet the Goldman Sachs Tax-Smart Bonds portfolio Our new Goldman Sachs Tax-Smart Bonds portfolio is industry-first, representing a unique opportunity for higher-income investors. The portfolio is designed to reduce risk compared to investing in stocks and increase after-tax yield compared to a cash account. Betterment does all the work for you behind the scenes to personalize the portfolio to your tax situation while leveraging Goldman Sachs' expertise in bond markets to aim to generate additional after-tax yield. But how does the portfolio work? Let’s look at an example of a hypothetical $100,000 investment… The power of after-tax yield The Goldman Sachs Tax-Smart Bonds portfolio is designed to generate additional after-tax yield compared to a cash account. By increasing after-tax yield, you may earn a higher return after taxes and fees than a regular high-yield cash account, which can be an advantage for high-income investors. Take a look at the standard yield and the after-tax yield of a hypothetical $100,000 placed in our Cash Reserve portfolio and our Goldman Sachs Tax-Smart Bonds portfolio by an investor in the 35% tax bracket.* Pre-Tax Yield After-Tax Yield** Take Home on $100,000 Cash Reserve 5.00% (variable)* 2.60% $2,595 Goldman Sachs Tax-Smart Bonds Portfolio 4.61% 2.85% $2,864 **Annualized Blended 30-day SEC Yield. After-tax assumes individual filing single in CA, 35% federal tax rate, and $260K income. Results may vary substantially. There are important risks to consider in comparing these products to each other, which we discuss in further detail below. The information provided is not tax advice and customers should obtain independent tax advice based on their particular situation. You can see that after taxes are paid, the Goldman Sachs portfolio comes out on top in our hypothetical scenario, which is illustrative only. What is after-tax yield, exactly? After-tax yield is the amount, expressed as a percentage of the investment, that you can expect to receive from an investment after paying taxes. We use after-tax yield to help you compare the potential profitability of portfolios that are taxed differently, such as our cash and bond portfolios. Municipal bonds are exempt from tax at the federal level, offering an after-tax benefit to higher income investors. Treasuries are exempt at the state level—particularly advantageous for those residing in high income tax states. After-tax yield for the Tax-Smart Bonds portfolio is calculated as the weighted average of 30-Day SEC yields for each ETF in the portfolio, net of fees (0.25%), and net of taxes, as determined by your Betterment profile data. After-tax yield reflects interest earned after fund expenses. How does the Goldman Sachs Tax-Smart Bonds portfolio take after-tax yield into account? Here’s how we work to take after-tax yield into account: First, Goldman Sachs built the portfolio with a mix of short-term bond ETFs containing treasury, municipal, and corporate bonds, which seek to offer lower risk than stock investing, leveraging their expertise in bond markets. Next, Betterment uses the information that you provide about your tax situation, including your state residency, federal tax bracket, and income, to personalize the portfolio for you. Finally, the portfolio strategy considers market conditions and taxable equivalent yields monthly. When you let Betterment know that your tax situation has changed and as interest rates shift, Betterment will rebalance your personalized portfolio. A spectrum of choices to optimize your cash At Betterment, we believe in investor choice. That’s why we continually create innovative portfolios to provide you with options based on your risk tolerance and desire for yield. And as interest rates evolve, your cash should still work for you. Diving deeper into your cash options When it comes to considering risk and yield—and choosing the portfolio right for you—we like to compare portfolio options across a few variables. First is the risk of losing money. With most investments, you potentially risk losing some of the amount of your initial investment, also called your “principal.” Our Cash Reserve account is the only portfolio offering FDIC insurance through program banks† to secure your money during volatile times. After Cash Reserve, our Goldman Sachs Tax-Smart Bonds portfolio is our option with the potential lower risk than investing in stocks where losses on principal, while still possible due to market volatility, are less likely. Second, we have liquidity. Liquidity is how easily (or not) available your funds are. It can be risky if your funds are locked up for a period of time, but you need them to cover expenses. All three portfolios provide access to your money when you need it (inclusive of standard ETF settlement times). Third, we account for tax. We offer tax-smart strategies to increase a portfolio’s after-tax yield. Our Goldman Sachs Tax-Smart Bonds portfolio offers this kind of tax-smart strategy designed for high-income investors. Breaking down the spectrum of portfolio choices available at Betterment Cash Reserve: If you want low risk, a Cash Reserve account can provide you the stated variable APY while preserving your funds in FDIC-insured accounts at our program banks. Goldman Sachs Tax-Smart Bonds: If you’re a higher-income investor (in a 32% federal tax bracket or above) and want to take more risk than Cash Reserve for the chance to potentially increase after-tax yield, then the Goldman Sachs Tax-Smart Bonds portfolio may be an option for you. BlackRock Target Income: If you’re comfortable with more risk than Cash Reserve and the Goldman Sachs Tax-Smart Bonds portfolio, our BlackRock Target Income portfolio is built to target income across four levels of risk while reducing volatility compared to stock portfolios. See which option might be best for you When you sign up for a bond investing account, Betterment will provide you with a personalized after-tax yield to help you compare our Cash Reserve account to our bond portfolios. Based on your degree of risk tolerance and the various after-tax yields of these three products, which are calculated based on the information provided to Betterment in your financial profile, you can select which portfolio is right for your goals and financial situation.

The Betterment Core portfolio strategy We continually improve our portfolio construction methodology over time in line with our research-focused investment philosophy. TABLE OF CONTENTS Introduction Global Diversification and Asset Allocation Portfolio Optimization Tax Management Using Municipal Bonds The Value Tilt Portfolio Strategy Innovative Technology Portfolio Strategy Conclusion Citations I. Introduction Betterment builds investment portfolios designed to help you make the most of your money so you can live the life you want. Our investment philosophy forms the basis for how we pursue that objective: Betterment uses real-world evidence and systematic decision-making to help increase our customers’ wealth. In building our platform and offering individualized advice, Betterment’s philosophy is actualized by our five investing principles. Regardless of one’s assets or specific situation, Betterment believes all investors should: Make a personalized plan. Build in discipline. Maintain diversification. Balance cost and value. Manage taxes. To align with Betterment’s investing principles, a portfolio strategy must enable personalized planning and built-in discipline for investors. The Betterment Core portfolio strategy contains 101 individualized risk levels (each with a different percentage of the portfolio invested in stocks vs. bonds, informed by your financial goals, time horizon and risk tolerance), in part, because that level of granularity in allocation management provides the flexibility to align to multiple goals with different timelines and circumstances. In this guide to the Betterment Core portfolio strategy construction process, our goal is to demonstrate how the methodology, in both its application and development, embodies Betterment’s investing principles. When developing a portfolio strategy, any investment manager faces two main tasks: asset class selection and portfolio optimization. Fund selection is also guided by our investing principles, and is covered separately in our Investment Selection Methodology paper. II. Global Diversification and Asset Allocation An optimal asset allocation is one that lies on the efficient frontier, which is a set of portfolios that seek to achieve the maximum objective for any given feasible level of risk. The objective of most long-term portfolio strategies is to maximize return for a given level of risk, which is measured in terms of volatility—the dispersion of those returns. In line with our investment philosophy of making systematic decisions backed by research, Betterment’s asset allocation is based on a theory by economist Harry Markowitz called Modern Portfolio Theory.1 A major tenet of Modern Portfolio Theory is that any asset included in a portfolio should not be assessed by itself, but rather, its potential risk and return should be analyzed as a contribution to the whole portfolio. Modern Portfolio Theory seeks to maximize expected return given an expected risk level or, equivalently, minimize expected risk given an expected return. Other forms of portfolio construction may legitimately pursue other objectives, such as optimizing for income, or minimizing loss of principal. Asset Classes Selected for Betterment’s Core Portfolio Strategy The Betterment Core portfolio strategy’s asset allocation starts with a universe of investable assets, which for us could be thought of as the “global market portfolio.”2 To capture the exposures of the asset classes for the global market portfolio, Betterment evaluates available exchange-traded funds (ETFs) that represent each class in the theoretical market portfolio. We base our asset class selection on ETFs because this aligns portfolio construction with our investment selection methodology. Betterment’s portfolios are constructed of the following asset classes: Equities U.S. equities International developed market equities Emerging market equities Bonds U.S. short-term treasury bonds U.S. inflation-protected bonds U.S. investment-grade bonds U.S. municipal bonds International developed market bonds Emerging market bonds We select U.S. and international developed market equities as a core part of the portfolio. Historically, equities exhibit a high degree of volatility, but provide some degree of inflation protection. Even though significant historical drawdowns, such as the global financial crisis in 2008 and pandemic outbreak in 2020, demonstrate the possible risk of investing in equities, longer-term historical data and our forward expected returns calculations suggest that developed market equities remain a core part of any asset allocation aimed at achieving positive returns. This is because, over the long term, developed market equities have tended to outperform bonds on a risk-adjusted basis. To achieve a global market portfolio, we also include equities from less developed economies, called emerging markets. Generally, emerging market equities tend to be more volatile than U.S. and international developed equities. And while our research shows high correlation between this asset class and developed market equities, their inclusion on a risk-adjusted basis is important for global diversification. Note that Betterment excludes frontier markets, which are even smaller than emerging markets, due to their widely varying definition, extreme volatility, small contribution to global market capitalization, and cost to access. The Betterment Core portfolio strategy incorporates bond exposure because, historically, bonds have a low correlation with equities, and they remain an important way to dial down the overall risk of a portfolio. To promote diversification and leverage various risk and reward tradeoffs, the Betterment Core portfolio strategy includes exposure to several asset classes of bonds. Asset Classes Excluded from the Betterment Core Portfolio Strategy While Modern Portfolio Theory would have us craft a portfolio to represent the total market, including all available asset classes, we exclude some asset classes whose cost and/or lack of data outweighs the potential benefit gained from their inclusion. The Betterment Core portfolio construction process excludes commodities and natural resources asset classes. Specifically, while commodities represent an investable asset class in the global financial market, we have excluded commodities ETFs because of their low contribution to a global stock/bond portfolio's risk-adjusted return. In addition, real estate investment trusts (REITs), which tend to be well marketed as a separate asset class, are not explicitly included in the Core portfolio strategy. Betterment does provide exposure to real estate, but as a sector within equities. Adding additional real estate exposure by including a REIT asset class would overweight the exposure to real estate relative to the overall market. Incorporating awareness of a benchmark Before 2024, we managed the Core portfolio strategy in a “benchmark agnostic” manner, meaning we did not incorporate consideration of global stock and bond indices in our portfolio optimization, though we have always sought to optimize the expected risk-adjusted return of the portfolios we construct for clients. The “risk” element of this statement represents volatility and the related drawdown potential of the portfolio, but it could also represent the risk in the deviation of the portfolio’s performance relative to a benchmark. In an evolution of our investment process, in 2024 we updated our portfolio construction methodology to become “benchmark aware,” as we now calibrate our exposures based on a custom benchmark that expresses our preference for diversifying across global stocks and bonds. A benchmark, which comes in the form of a broad-based market index or a combination of indices, serves as a reference point when approaching asset allocation, understanding investment performance, and aligning the expectations of portfolio managers and clients. In our case, we created a custom benchmark that most closely aligns with our future expectations for global markets. The custom benchmark we have selected is composed of (1) the MSCI All Country World stock index (MSCI ACWI), (2) the Bloomberg Global Aggregate Bond index, and (3) at low risk levels, the ICE US Treasury 1-3 Year Index. Our custom benchmark is composed of 101 risk levels of varying percentage weightings of the stock and bond indexes, which correspond to the 101 risk level allocations in our Core portfolio. At low risk levels (allocations that are less than 40% stocks), we layer an allocation to the ICE US Treasury 1-3 Year index, which represents short-term bonds, into the blended benchmark. We believe that incorporating this custom benchmark into our process reinforces the discipline of carefully evaluating the ways in which our portfolios’ performance could veer from global market indices and deviate from our clients’ expectations. We have customized the benchmark with 101 risk levels so that it serves clients’ varying investment goals and risk tolerances. As we will explore in the following section, establishing a benchmark allows us to apply constraints to our portfolio optimization that ensures the portfolio strategy’s asset allocation does not vary significantly from the geographic and market-capitalization size exposures of a sound benchmark. Our benchmark selection also makes explicit that the portfolio strategy delivers global diversification rather than the more narrowly concentrated and home-biased exposures of other possible benchmarks such as the S&P 500. III. Portfolio Optimization As an asset manager, we fine-tune the investments our clients hold with us, seeking to maximize return potential for the appropriate amount of risk each client can tolerate. We base this effort on a foundation of established techniques in the industry and our own rigorous research and analysis. While most asset managers offer a limited set of model portfolios at a defined risk scale, the Betterment Core portfolio strategy is designed to give customers more granularity and control over how much risk they want to take on. Instead of offering a conventional set of three portfolio choices—aggressive, moderate, and conservative—our portfolio optimization methods enable the Core portfolio strategy to contain 101 different risk levels. Optimizing Portfolios Modern Portfolio Theory requires estimating variables such as expected-returns, covariances, and volatilities to optimize for portfolios that sit along an efficient frontier. We refer to these variables as capital market assumptions (CMAs), and they provide quantitative inputs for our process to derive favorable asset class weights for the portfolio strategy. While we could use historical averages to estimate future returns, this is inherently unreliable because historical returns do not necessarily represent future expectations. A better way is to utilize the Capital Asset Pricing Model (CAPM) along with a utility function which allows us to optimize for the portfolio with a higher return for the risk that the investor is willing to accept. Computing Forward-Looking Return Inputs Under CAPM assumptions, the global market portfolio is the optimal portfolio. Since we know the weights of the global market portfolio and can reasonably estimate the covariance of those assets, we can recover the returns implied by the market.3 This relationship gives rise to the equation for reverse optimization: μ = λ Σ ωmarket Where μ is the return vector, λ is the risk aversion parameter, Σ is the covariance matrix, and ωmarket is the weights of the assets in the global market portfolio.5 By using CAPM, the expected return is essentially determined to be proportional to the asset’s contribution to the overall portfolio risk. It’s called a reverse optimization because the weights are taken as a given and this implies the returns that investors are expecting. While CAPM is an elegant theory, it does rely on a number of limiting assumptions: e.g., a one period model, a frictionless and efficient market, and the assumption that all investors are rational mean-variance optimizers.4 In order to complete the equation above and compute the expected returns using reverse optimization, we need the covariance matrix as an input. This matrix mathematically describes the relationships of every asset with each other as well as the volatility risk of the assets themselves. In another more recent evolution of our investment process, we also attempt to increase the robustness of our CMAs by averaging in the estimates of expected returns and volatilities published by large asset managers such as BlackRock, Vanguard, and State Street Global Advisors. We weight the contribution of their figures to our final estimates based on our judgment of the external provider’s methodology. Constrained optimization for stock-heavy portfolios After formulating our CMAs for each of the asset classes we favor for inclusion in the Betterment Core portfolio strategy, we then solve for target portfolio allocation weights (the specific set of asset classes and the relative distribution among those asset classes in which a portfolio will be invested), with the range of possible solutions constrained by limiting the deviation from the composition of the custom benchmark. To robustly estimate the weights that best balance risk and return, we first generate several thousand random samples of 15 years of expected returns for the selected asset classes based on our latest CMAs, assuming a multivariate normal distribution. For each sample of 15 years of simulated expected return data, we find a set of allocation weights subject to constraints that provide the best risk-return trade-off, expressed as the portfolio’s Sharpe ratio, i.e., the ratio of its return to its volatility. Averaging the allocation weights across the thousands of return samples gives a single set of allocation weights optimized to perform in the face of a wide range of market scenarios (a “target allocation”). The constraints are imposed to make the portfolio weights more benchmark-aware by setting maximum and minimum limits to some asset class weights. These constraints reflect our judgment of how far the composition of geographic regions within the portfolio’s stock and bond allocations should differ from the breakdown of the indices used in the benchmark before the risk of significantly varied performance between the portfolio strategy and the benchmark becomes untenable. For example, the share of the portfolio’s stock allocation assigned to international developed stocks should not be profoundly different from the share of international developed stocks within the MSCI ACWI. We implement caps on the weights of emerging market stocks and bonds, which are often projected to have high returns in our CMAs, and set minimum thresholds for U.S. stocks and bonds. This approach not only ensures our portfolio aligns more closely with the benchmark, but it also mitigates the risk of disproportionately allocating to certain high expected return asset classes. Constrained optimization for bond-heavy portfolios For versions of the Core portfolio strategy that have more than or equal to 60% allocation to bonds, the optimization approach differs in that expected returns are maximized for target volatilities assigned to each risk level. These volatility targets are determined by considering the volatility of the equivalent benchmark. Manually established constraints are designed to manage risk relative to the benchmark, instituting a declining trend in emerging market stock and bond exposures as stock allocations (i.e., the risk level) decreases. Meaning that investors with more conservative risk tolerances have reduced exposures to emerging market stocks and bonds because emerging markets tend to have more volatility and downside-risk relative to more established markets. Additionally, as the stock allocation percentage decreases, we taper the share of international and U.S. aggregate bonds within the overall bond allocation, and increase the share of short-term Treasury, short-term investment grade, and inflation-protected bonds. This reflects our view that investors with more conservative risk tolerances should have increased exposure to short-term Treasury, short-term investment grade, and inflation-protected bonds relative to riskier areas of fixed income. The lower available risk levels of the Core portfolio strategy demonstrate capital preservation objectives, as the shorter-term fixed income exposures likely possess less credit and duration risk. Clients invested in the Core portfolio at conservative allocation levels will likely therefore not experience as significant drawdowns in the event of waves of defaults or upward swings in interest rates. Inflation-protected securities also help buffer the lower risk levels from upward drafts in inflation. IV. Tax Management Using Municipal Bonds For investors with taxable accounts, portfolio returns may be further improved on an after-tax basis by utilizing municipal bonds. This is because the interest from municipal bonds is exempt from federal income tax. To take advantage of this, the Betterment Core portfolio strategy in taxable accounts is also tilted toward municipal bonds because interest from municipal bonds is exempt from federal income tax, which can further optimize portfolio returns. Other types of bonds remain for diversification reasons, but the overall bond tax profile is improved by tilting towards municipal bonds. For investors in states with some of the highest tax rates—New York and California—Betterment can optionally replace the municipal bond allocation with a more narrow set of bonds for that specific state, further saving the investor on state taxes. Betterment customers who live in NY or CA can contact customer support to take advantage of state specific municipal bonds. V. The Value Tilt Portfolio Strategy Existing Betterment customers may recall that historically the Core portfolio strategy held a tilt to value companies, or businesses that appear to be potentially undervalued based on metrics such as price to earnings ratios. The latest iteration of the Core portfolio strategy, however, has deprecated this explicit tilt that was expressed via large-, mid-, and small-capitalization U.S. value stock ETFs, while maintaining some exposure to value companies through broad market U.S. stock funds. We no longer favor allocating to value stock ETFs within the Core portfolio strategy in large part as a result of our adoption of a broad market benchmark, which highlights the idiosyncratic nature of such tilts, sometimes referred to as “off benchmark bets.” We believe our chosen benchmark that represents stocks through the MSCI ACWI, which holds a more neutral weighting to value stocks, more closely aligns with the risk and return expectations of Betterment’s diverse range of client types across individuals, financial advisors, and 401(k) plan sponsors. Additionally, as markets have grown more efficient and value factor investing more popularized, potentially compressing the value premium, we have a marginally less favorable view of the forward-looking, risk-adjusted return profile of the exposure. That being said, we have not entirely lost conviction in the research supporting the prudence of value investing. The value factor’s deep academic roots drove decisions to incorporate the value tilt into Betterment’s portfolios from the company’s earliest days. For investors who wish to remain invested in a value strategy, we have added the Value Tilt portfolio strategy, a separate option from the Core portfolio strategy to our investing offering. The Value Tilt portfolio strategy maintains the Core portfolio strategy’s global diversification across stocks and bonds while including a sleeve within the stock allocation of large-, mid-, and small-capitalization U.S. value funds. We calibrated the size of the value fund exposure based on a certain target historical tracking error to the backtested performance of the latest version of the Core portfolio strategy. Based on this approach, investors should expect the Value Tilt portfolio strategy to generally perform similarly to Core, with the potential to under- or outperform based on the return of U.S. value stocks. With the option to select between the Value Tilt portfolio strategy or a Core now without an explicit allocation to value, the investment flexibility of the Betterment platform has improved. VI. Innovative Technology Portfolio Strategy In 2021, Betterment launched the Innovative Technology portfolio strategy to provide access to the thematic trend of technological innovation. The premise of investing in this theme is that your investments incorporate exposure to the companies that are seeking to shape the next industrial revolution. Similar to the Value Tilt portfolio, the Core portfolio strategy is used as the foundation of construction for the Innovative Technology portfolio. With this portfolio strategy, we calibrated the size of the innovative technology fund exposure based on a certain target historical tracking error to the backtested performance of the latest version of the Core portfolio strategy. Through this process, the Innovative Technology portfolio maintains the same globally diversified, low-cost approach that is found in Betterment’s investment philosophy. The portfolio however has increased exposure to risk given that innovation requires a long-term view, and may face uncertainties along the way. It may outperform or underperform depending on the return experience of the innovative technology fund exposure and the thematic landscape. VII. Conclusion After setting the strategic weight of assets in the Betterment Core portfolio strategy, the next step in implementing the portfolio construction process is Betterment’s investment selection, which selects the appropriate ETFs for the respective asset exposure in a generally low-cost, tax-efficient way. In keeping with our philosophy, that process, like the portfolio construction process, is executed in a systematic, rules-based way, taking into account the cost of the fund and the liquidity of the fund. Beyond ticker selection is our established process for allocation management—how we advise downgrading risk over time—and our methodology for automatic asset location, which we call Tax Coordination. Finally, our overlay features of automated rebalancing and tax-loss harvesting are designed to be used to help further maximize individualized, after-tax returns. Together these processes put our principles into action, to help each and every Betterment customer maximize value while invested at Betterment and when they take their money home. VIII.

Socially Responsible Investing Portfolios Methodology Learn how Betterment constructs our Socially Responsible Investing (SRI) portfolios. Table of Contents Introduction How do we define SRI? The Challenges of SRI Portfolio Construction How is Betterment’s Broad Impact portfolio constructed? How is Betterment’s Climate Impact portfolio constructed? How is Betterment’s Social Impact portfolio constructed? Conclusion Introduction Betterment launched its first Socially Responsible Investing (SRI) portfolio in 2017, and has widened the investment options under that umbrella since then. Within Betterment’s SRI options, we currently offer a Broad Impact portfolio and two additional, more focused SRI portfolio options: a Social Impact SRI portfolio (focused on social governance mandates) and a Climate Impact SRI portfolio (focused on climate-conscious investments). These portfolios represent a diversified, relatively low-cost solution constructed using exchange traded funds (ETFs), which will be continually improved upon as costs decline, more data emerges, and as a result, the availability of SRI funds broadens. How do we define SRI? Our approach to SRI has three fundamental dimensions that shape our portfolio construction mandates: Reducing exposure to investments involved in unsustainable activities and environmental, social, or governmental controversies. Increasing exposure to investments that work to address solutions for core environmental and social challenges in measurable ways. Allocating to investments that use shareholder engagement tools, such as shareholder proposals and proxy voting, to incentivize socially responsible corporate behavior. SRI is the traditional name for the broad concept of values-driven investing (many experts now favor “sustainable investing” as the name for the entire category). Our SRI approach uses SRI mandates based on a set of industry criteria known as “ESG,” which stands for Environmental, Social and Governance. ESG refers specifically to the quantifiable dimensions of a company’s standing along each of its three components. Betterment’s approach expands upon the ESG-investing framework with exposure to investments that use complementary shareholder engagement tools. Betterment does not directly select companies to include in, or exclude from, the SRI portfolios. Rather, Betterment identifies ETFs that have been classified as ESG or similar by third-parties and considers internally developed “SRI mandates” alongside other qualitative and quantitative factors to select ETFs to include in its SRI portfolios. Using SRI Mandates One aspect of improving a portfolio’s ESG exposure is reducing exposure to companies that engage in certain activities that may be considered undesirable because they do not align with specific values. These activities may include selling tobacco, military weapons, civilian firearms, as well as involvement in recent and ongoing ESG controversies. However, SRI is about more than just adjusting your portfolio to minimize companies with a poor social impact. For each Betterment SRI portfolio, the portfolio construction process considers one or more internally developed “SRI mandates.” Betterment’s SRI mandates are sustainable investing objectives that we include in our portfolios’ exposures. SRI Mandate Description Betterment SRI Portfolio Mapping ESG Mandate ETFs tracking indices which are constructed with reference to some form of ESG optimization, which promotes exposure to Environmental, Social, and Governance pillars. Broad, Climate, Social Impact Portfolios Fossil Fuel Divestment Mandate ETFs tracking indices which are constructed with the aim of excluding stocks in companies with major fossil fuels holdings (divestment). Climate Impact Portfolio Carbon Footprint Mandate ETFs tracking indices which are constructed with the aim of minimizing exposure to carbon emissions across the entire economy (rather than focus on screening out exposure to stocks primarily in the energy sector). Climate Impact Portfolio Green Financing Mandates ETFs tracking indices focused on financing environmentally beneficial activities directly. Climate Impact Portfolio Gender Equity Mandate ETFs tracking indices which are constructed with the aim of representing the performance of companies that seek to advance gender equality. Social Impact Portfolio Racial Equity Mandate ETFs tracking indices which are constructed with the aim of allocating capital to companies that seek to advance racial equality. Social Impact Portfolio Shareholder Engagement Mandate In addition to the mandates listed above, Betterment’s SRI portfolios are constructed using a shareholder engagement mandate. One of the most direct ways a shareholder can influence a company’s decision making is through shareholder proposals and proxy voting. Publicly traded companies have annual meetings where they report on the business’s activities to shareholders. As a part of these meetings, shareholders can vote on a number of topics such as share ownership, the composition of the board of directors, and executive level compensation. Shareholders receive information on the topics to be voted on prior to the meeting in the form of a proxy statement, and can vote on these topics through a proxy card. A shareholder can also make an explicit recommendation for the company to take a specific course of action through a shareholder proposal. ETF shareholders themselves do not vote in the proxy voting process of underlying companies, but rather the ETF fund issuer participates in the proxy voting process on behalf of their shareholders. As investors signal increasing interest in ESG engagement, more ETF fund issuers have emerged that play a more active role engaging with underlying companies through proxy voting to advocate for more socially responsible corporate practices. These issuers use engagement-based strategies, such as shareholder proposals and director nominees, to engage with companies to bring about ESG change and allow investors in the ETF to express a socially responsible preference. For this reason, Betterment includes a Shareholder Engagement Mandate in its SRI portfolios. Mandate Description Betterment SRI Portfolio Mapping Shareholder Engagement Mandate ETFs which aim to fulfill one or more of the above mandates, not via allocation decisions, but rather through the shareholder engagement process, such as proxy voting. Broad, Climate, Social Impact Portfolios The Challenges of SRI Portfolio Construction For Betterment, three limitations have a large influence on our overall approach to building an SRI portfolio: 1. Many existing SRI offerings in the market have serious shortcomings. Many SRI offerings today sacrifice sufficient diversification appropriate for investors who seek market returns, and/or do not provide investors an avenue to use collective action to bring about ESG change. Betterment’s SRI portfolios do not sacrifice global diversification. Consistent with our core principle of global diversification and to ensure both domestic and international bond exposure, we’re still allocating to some funds without an ESG mandate, until satisfactory solutions are available within those asset classes. Additionally, all three of Betterment’s SRI portfolios include a partial allocation to an engagement-based socially responsible ETF using shareholder advocacy as a means to bring about ESG-change in corporate behavior. Engagement-based socially responsible ETFs have expressive value in that they allow investors to signal their interest in ESG issues to companies and the market more broadly, even if particular shareholder campaigns are unsuccessful. 2. Integrating values into an ETF portfolio may not always meet every investor’s expectations. For investors who prioritize an absolute exclusion of specific types of companies above all else, certain approaches to ESG will inevitably fall short of expectations. For example, many of the largest ESG funds focused on US Large Cap stocks include some energy companies that engage in oil and natural gas exploration, like Hess. While Hess might not meet the criteria of the “E” pillar of ESG, it could still meet the criteria in terms of the “S” and the “G.” Understanding that investors may prefer to focus specifically on a certain pillar of ESG, Betterment has made three SRI portfolios available. The Broad Impact portfolio seeks to balance each of the three dimensions of ESG without diluting different dimensions of social responsibility. With our Social Impact portfolio, we sharpen the focus on social equity with partial allocations to gender and racial diversity focused funds. With our Climate Impact portfolio, we sharpen the focus on controlling carbon emissions and fostering green solutions. 3. Most available SRI-oriented ETFs present liquidity limitations. While SRI-oriented ETFs have relatively low expense ratios compared to SRI mutual funds, our analysis revealed insufficient liquidity in many ETFs currently on the market. Without sufficient liquidity, every execution becomes more expensive, creating a drag on returns. Median daily dollar volume is one way of estimating liquidity. Higher volume on a given asset means that you can quickly buy (or sell) more of that asset in the market without driving the price up (or down). The degree to which you can drive the price up or down with your buying or selling must be treated as a cost that can drag down on your returns. We expect that increased asset flows across the industry into such SRI-oriented ETFs will continue to drive down expense ratios and increase liquidity over the long-run. To that end, Betterment reassesses the funds available for inclusion in these portfolios regularly. In balancing cost and value for the portfolios, the options are limited to funds of certain asset classes such as US stocks, Developed Market stocks, Emerging Market stocks, US Investment Grade Corporate Bonds, and US High Quality bonds. How is Betterment’s Broad Impact portfolio constructed? Betterment’s Broad Impact portfolio invests assets in socially responsible ETFs to obtain exposure to both the ESG and Shareholder Engagement mandates, as highlighted in the table above. It focuses on ETFs that consider all three ESG pillars, and includes an allocation to an engagement-based SRI ETF. Broad ESG investing solutions are currently the most liquid, highlighting their popularity amongst investors. In order to maintain geographic and asset class diversification and to meet our requirements for lower cost and higher liquidity in all SRI portfolios, we continue to allocate to some funds that do not reflect SRI mandates, particularly in bond asset classes. How is Betterment’s Climate Impact portfolio constructed? Betterment offers a Climate Impact portfolio for investors that want to invest in an SRI strategy more focused on the environmental pillar of “ESG” rather than focusing on all ESG dimensions equally. Betterment’s Climate Impact portfolio invests assets in socially responsible ETFs and is constructed using the following mandates that seek to achieve divestment and engagement: ESG, carbon footprint reduction, fossil fuel divestment, shareholder engagement, and green financing. The Climate Impact portfolio was designed to give investors exposure to climate-conscious investments, without sacrificing proper diversification and balanced cost. Fund selection for this portfolio follows the same guidelines established for the Broad Impact portfolio, as we seek to incorporate broad based climate-focused ETFs with sufficient liquidity relative to their size in the portfolio. How can the Climate Impact portfolio help to positively affect climate change? The Climate Impact portfolio is allocated to iShares MSCI ACWI Low Carbon Target ETF (CRBN), an ETF which seeks to track the global stock market, but with a bias towards companies with a lower carbon footprint. By investing in CRBN, investors are actively supporting companies with a lower carbon footprint, because CRBN overweights these stocks relative to their high-carbon emitting peers. One way we can measure the carbon impact a fund has is by looking at its weighted average carbon intensity, which measures the weighted average of tons of CO2 emissions per million dollars in sales, based on the fund's underlying holdings. Based on weighted average carbon intensity data from MSCI, Betterment’s 100% stock Climate Impact portfolio has carbon emissions per unit sales that are nearly 50% lower than Betterment’s 100% stock Core portfolio as of February 8, 2024. Additionally, a portion of the Climate Impact portfolio is allocated to fossil fuel reserve funds. Rather than ranking and weighting funds based on a certain climate metric like CRBN, fossil fuel reserve free funds instead exclude companies that own fossil fuel reserves, defined as crude oil, natural gas, and thermal coal. By investing in fossil fuel reserve free funds, investors are actively divesting from companies with some of the most negative impact on climate change, including oil producers, refineries, and coal miners such as Chevron, ExxonMobile, BP, and Peabody Energy. Another way that the Climate Impact portfolio promotes a positive environmental impact is by investing in bonds that fund green projects. The Climate Impact portfolio invests in iShares Global Green Bond ETF (BGRN), which tracks the global market of investment-grade bonds linked to environmentally beneficial projects, as determined by MSCI. These bonds are called “green bonds.” The green bonds held by BGRN fund projects in a number of environmental categories defined by MSCI including alternative energy, energy efficiency, pollution prevention and control, sustainable water, green building, and climate adaptation. How is Betterment’s Social Impact portfolio constructed? Betterment offers a Social Impact portfolio for investors that want to invest in a strategy more focused on the social pillar of ESG investing (the S in ESG). Betterment’s Social Impact portfolio invests assets in socially responsible ETFs and is constructed using the following mandates: ESG, gender equity, racial equity, and shareholder engagement. The Social Impact portfolio was designed to give investors exposure to investments which promote social equity, without sacrificing proper diversification and balanced cost. Fund selection for this portfolio follows the same guidelines established for the Broad Impact portfolio discussed above, as we seek to incorporate broad based ETFs that focus on social equity with sufficient liquidity relative to their size in the portfolio. How does the Social Impact portfolio help promote social equity? The Social Impact portfolio shares many of the same holdings as Betterment’s Broad Impact portfolio. The Social Impact portfolio additionally looks to further promote the “social” pillar of ESG investing, by allocating to two ETFs that specifically focus on diversity and inclusion -- Impact Shares NAACP Minority Empowerment ETF (NACP) and SPDR SSGA Gender Diversity Index ETF (SHE). NACP is a US stock ETF offered by Impact Shares that tracks the Morningstar Minority Empowerment Index. The National Association for the Advancement of Colored People (NAACP) has developed a methodology for scoring companies based on a number of minority empowerment criteria. These scores are used to create the Morningstar Minority Empowerment Index, an index which seeks to maximize the minority empowerment score while maintaining market-like risk and strong diversification. The end result is an index which provides greater exposure to US companies with strong diversity policies that empower employees irrespective of race or nationality. By investing in NACP, investors are allocating more of their money to companies with a track record of social equity as defined by the NAACP. SHE is a US Stock ETF that allows investors to invest in more female-led companies compared to the broader market. In order to achieve this objective, companies are ranked within each sector according to their ratio of women in senior leadership positions. Only companies that rank highly within each sector are eligible for inclusion in the fund. By investing in SHE, investors are allocating more of their money to companies that have demonstrated greater gender diversity within senior leadership than other firms in their sector. For more information about these social impact ETFs, including any associated risks, please see our disclosures. Should we expect any difference in an SRI portfolio’s performance? One might expect that a socially responsible portfolio could lead to lower returns in the long term compared to another, similar portfolio. The notion behind this reasoning is that somehow there is a premium to be paid for investing based on your social ideals and values. A white paper written in partnership between Rockefeller Asset Management and NYU Stern Center for Sustainable Business studied 1,000+ research papers published from 2015-2020 analyzing the relationship between ESG investing and performance. The primary takeaway from this research was that they found “positive correlations between ESG performance and operational efficiencies, stock performance, and lower cost of capital.” When ESG factors were considered in the study, there seemed to be improved performance potential over longer time periods and potential to also provide downside protection during periods of crisis. It’s important to note that performance in the SRI portfolios can be impacted by several variables, and is not guaranteed to align with the results of this study. Dividend Yields Could Be Lower Using the SRI Broad Impact portfolio for reference, dividend yields over a one year period ending February 8, 2024 indicate that SRI income returns at certain risk levels have been lower than those of Core portfolio. Oil and gas companies like BP, Chevron, and Exxon, for example, currently have relatively high dividend yields and excluding them from a given portfolio can cause its income return to be lower. Of course, future dividend yields are uncertain variables and past data may not provide accurate forecasts. Nevertheless, lower dividend yields can be a factor in driving total returns for SRI portfolios to be lower than those of Core portfolios. Comparison of Dividend Yields Source: Bloomberg, Calculations by Betterment for one year period ending February 8, 2024. Dividend yields for each portfolio are calculated using the dividend yields of the primary ETFs used for taxable allocations of Betterment’s portfolios as of February 2024. Conclusion Despite the various limitations that all SRI implementations face today, Betterment will continue to support its customers in further aligning their values to their investments. Betterment may add additional socially responsible funds to the SRI portfolios and replace other ETFs as more socially responsible products become available.

The latest update to our Core portfolio strategy Learn more about the changes we believe will help improve long-term risk-adjusted returns. Betterment serves as a fiduciary, acting in our clients’ best interests. We monitor our portfolios and review the underlying investments on a regular basis to optimize portfolios and help you achieve your investment goals. As part of this process, we’ve made changes to our Core portfolio strategy that we believe will help improve long-term risk-adjusted returns. How we evaluate and manage our portfolios The Betterment Investment Committee monitors and reviews the underlying inputs used to construct our portfolios, including running simulations to gauge expected long-term performance. Our capital market assumptions (CMAs) represent our long-term expectations for the return and risk of various asset classes. These CMAs help inform how we allocate across different asset classes in our portfolios, and power our platform’s advice tools What’s changed in the Core portfolio? Our updated CMAs indicate a shift in the expected risk-return profile of certain asset classes, suggesting a reallocation of target exposures with the Core portfolio going forward. Here’s what that means: Within our equities basket Dialed down exposure to emerging markets stocks while increasing exposure to U.S. stocks. With increasing geopolitical risks, we believe this shift can help reduce potential losses, especially for portfolios holding fewer stocks relative to bonds. This change also brings us closer to MSCI All Country World Index (MSCI ACWI, our stock allocation benchmark as described below) Reduced the emphasis on U.S. value stocks (“value tilt”), shifting toward U.S. stock exposure weighted by market capitalization. Over time, we’ve observed gradual compression in the value factor premium as markets have become more efficient. We expect this adjustment to help reduce risk and more closely align the Core portfolio with our custom benchmark indices (described below). Within our fixed income basket Reduced exposure to both emerging markets and international developed bonds, while increasing exposure to U.S. bonds. Similar to our stock allocations, we expect this to mitigate potential downside risk for more conservative allocations. Increased allocations to inflation-protected U.S. bonds. This update will help shield clients with more conservative portfolios from potential erosion risk on savings—providing protection against market drawdowns, rising interest rates, and other macroeconomic events that could have negative short-term consequences. This change can be particularly relevant for customers in retirement, since inflation can meaningfully eat away at the value of your money over time. Developing a “benchmark aware” portfolio strategy In an evolution of our investment process, we’ve also updated our Core portfolio construction methodology to become more “benchmark aware.” This means we now calibrate our exposures based on a custom benchmark. The custom benchmark we have selected is composed of (1) the MSCI All Country World Index (MSCI ACWI), (2) the Bloomberg Global Aggregate Bond index, and (3) at low risk levels, the ICE US Treasury 1-3 Year Index. This custom benchmark has varying risk levels that correspond to the Core portfolio allocations we support for a variety of investor risk tolerances. Introducing the Value Tilt portfolio strategy For customers who favor the potential benefits and associated risks in value investing, we’re introducing a new portfolio option: Value Tilt. The Value Tilt portfolio strategy maintains the same historical track record as the Core portfolio strategy, up until the 2024 changes where this becomes a new strategy. While this portfolio includes the same thematic asset allocation changes as the Core portfolio strategy, it maintains explicit weighting towards U.S. value stocks. An expansion of our portfolio options, Value Tilt is available for all goals, new and old. You can select it within your account. What does all this mean for you? No action is required from you to transition to the updated Core portfolio allocations. We’ll manage your Core portfolio tax-efficiently and put your cash flows (such as deposits, withdrawals, dividends, contributions, and distributions) to work to assist with the transition, moving your portfolio towards the updated target allocation. Our algorithms will automatically work to reduce any drift between your positions and the updated target allocation, by (1) first purchasing those funds where your portfolio is underweight when investing dividends and deposits and (2) first selling those funds where your portfolio is overweight, when generating cash for withdrawals. If you’ve enabled tax loss harvesting, we’ll use those opportunities to reduce drift as well. We do not expect any tax impact in IRAs, 401(k)s, and HSAs. Considering potential tax impact For taxable goals, while the trade-off between expected returns and tax impact is unique to each client (and depends on factors such as your investing time horizon and financial situation), most customers should see minimal changes to their taxes as a result of this transition. That’s because we’re taking a gradual approach with the portfolio migration and using cash flows to transition taxable accounts. If you would rather be invested in one of our other managed ETF portfolio strategies or wish to have value exposure in your portfolio, you have the option of selecting any of these strategies, along with the Value Tilt portfolio, on our platform. Betterment is regularly monitoring your investments so that you don’t have to. Learn more about our investment philosophy and process.

A simple way to invest in Bitcoin and Ethereum Since cryptocurrencies were first released in 2009, Bitcoin and Ethereum have established themselves as the largest digital assets. What to know: At Betterment, we’ve made it easy for you to invest directly in the most well-known and adopted digital assets through our Bitcoin/Ethereum portfolio. A simple, balanced approach to crypto: Our Bitcoin (BTC) and Ethereum (ETH) portfolio simplifies investing in the largest, most liquid digital assets. Together, BTC and ETH can make up about 60% to 70% of the crypto market capitalization depending on the market conditions. The portfolio has target weights of 70% BTC and 30% ETH relative to each coin's market capitalization. Once your account has reached the balance threshold, we automatically rebalance the portfolio for you to maintain as close as possible to the 70/30 split. Fast facts: The price of Bitcoin and Ethereum are considered indicators of the overall health of the crypto markets but there are key differences between the two assets. Bitcoin, launched in 2009, and Ethereum, launched in 2015, are both digital currencies and decentralized blockchains (a distributed peer-to-peer database). The Bitcoin blockchain records BTC transactions, with the original goal of BTC being a medium of exchange and a store of value outside the control of individuals, banks, or institutions. The Ethereum blockchain is used to record ETH transactions but its distinguishing feature is ‘smart contracts’ used across industries including finance, e-commerce, and real estate. Generally, there are two other ways to invest in BTC and ETH: Investors can manually select BTC and ETH on crypto exchanges but have to take care of monitoring the market and rebalancing their investments in a crypto wallet. Exchange-traded products including ETFs and trusts provide investors with easy exposure to BTC and ETH but the price of the investment doesn’t always track the price of the digital asset, plus these investments don’t provide true ownership of the underlying cryptocurrency. Both of these approaches are considerably different than ours. The Betterment Bitcoin/Ethereum portfolio is designed to give you ownership of both BTC and ETH while we rebalance the portfolio for you as the market changes.

Three ways to get the most out of your Cash Reserve account Let's take your cash game to the next level. Here are three tips to help manage your Cash Reserve account for long-term success. You're smart. You already have a Cash Reserve account (or you want one!). And you know the value of a high-yield account with FDIC insurance up to $2 million through our program banks†. Let's take your cash game to the next level. Why it matters: A Cash Reserve account is a place to grow your savings and secure your money during volatile times. But we also give you tools and tips to make the most of your cash, whether that’s saving for a goal or using cash to eventually invest in stocks and bonds. Here are three simple ways to level up your cash skills: #1 Have multiple goals and use the goal forecaster: You can have more than one Cash Reserve account to track your savings for different purchases or needs. To set up a new Cash Reserve account: Select “New cash goal” when you are opening a Cash Reserve account. You’ll be able to name your goal and set a target amount and target date to track your progress. To use the goal forecaster: On a desktop device, navigate to your cash goal account and click the “Open goal forecaster” button. You can enter different scenarios for a recurring deposit, a one-time deposit, and a target date. Our projection graph will show you the estimated chance of reaching your goal for each scenario you enter. #2 Pay yourself first with a consistent recurring deposit from your external account: The easiest way to pay yourself first is to automate it, saving you time while increasing your savings. Why use a recurring deposit to save? Think of the amount you save monthly just like a mandatory expense, no different than a phone bill or a mortgage payment. Each month, you can automatically send money from your external checking or savings account to your Cash Reserve account getting you one step closer to reaching your goal. How do you do it? In your Betterment account, click the Deposit button, select your “to” and “from” accounts, and adjust the frequency to meet your needs. #3 Balance short-term liquidity and long-term growth: Your Cash Reserve account is liquid, meaning it’s easy to access your cash. But it’s important to strike the right balance between cash for short-term needs and investments for long-term growth. Do you have an emergency fund? If you have already saved three to six months of living expenses then you should take a look at your extra cash. If you don’t have other short-term savings goals, investing in stocks and bonds may help to grow your money over time. Are your goals short-term or long-term? A Cash Reserve account may help you achieve short-term goals since you need the money soon and don’t want to lose it if stocks fall. But for goals longer than 12 months, consider stock and bond investing. While investing involves more risk, historically, stocks have had greater long-term gains than cash. Similar to a Cash Reserve goal, you can select an investing goal and we’ll recommend a portfolio to match your target date.
