Data as of June 30, 2018 MODEL PORTFOLIO STOCK AND BOND MIX Choosing the appropriate mix of investments is the most important decision an investor can make. Historically, stocks are riskier but have higher expected returns, while bonds are generally less volatile but have lower expected returns. Striking a proper balance is specific to each individual. This illustration reflects the balance in your portfolio and the potential for fluctuations in its value. Holdings are subject to change. BONDS STOCKS PORTFOLIO CHARACTERISTICS Mutual funds derive their characteristics and value from the securities held by the fund. Analyzing the combined underlying holdings can help determine the portfolio s exposure to various types of securities and global markets. Model Portfolio allocation is based on the underlying holdings and portfolio weights in the funds shown on page 1.

OVERWEIGHT TO VALUE +17% Data as of June 30, 2018 MODEL PORTFOLIO EXPOSURE TO STOCKS Stocks are riskier than most bonds and have historically offered higher expected returns. But not all stocks are the same. Small company ( small cap ) stocks have offered higher expected returns than large cap stocks, and lower-priced value stocks have offered higher expected returns than higher-priced growth stocks over time. Consequently, increased exposure to small cap and value stocks may improve a portfolio s long-term expected return. The squares below compare the stock weights in the model portfolio to those in a total market index based on the size and relative price dimensions. The tables below show the portfolio s combined exposure to stocks in various countries and the top stocks of all funds combined. The large arrows below and to the left of the squares indicate the model s overweighting to small cap and value stocks relative to the market.

Model weights are based on the underlying holdings of the funds listed on page 1. Companies are classified as small and large by computing breakpoints based on total market capitalization in each country or region. See Analysis Methodology in the Appendix for more detailed information. MODEL PORTFOLIO EXPOSURE TO BONDS Bonds and cash are usually less volatile than stocks, but they historically have offered investors lower returns. Bond yields are generally driven by two dimensions: term and credit. Term (or maturity) refers to the time to principal repayment, while credit quality is a measure of an issuer s ability to repay interest and principal on time. Credit quality is subject to change and credit ratings do not eliminate market risk. 75% 25% AAA/AA A/BBB BB/Below/ NR 0% 4% Highest Credit Quality Lowest Shortest Maturity (Years) Longest 0-1 Years 96% 1-5 Years 0% 0% 5-10 Years 10+ Years TOP CURRENCY EXPOSURES (PRE-HEDGED) Weight UNITED STATES DOLLAR 91.3% EURO 5.1% SWEDISH KRONA 2.1% CANADIAN DOLLAR 0.8% AUSTRALIAN DOLLAR 0.7% TOTAL 100.0% BOND CATEGORIES EXPOSURE Weight GOVERNMENT BONDS 65.7% CORPORATE BONDS / PAPER 34.3% TREASURY INFLATION PROTECTED SECURITIES 0.0% MUNICIPAL BONDS / PAPER 0.0% FLOATING RATE NOTES / CD'S 0.0% TOTAL 100.0% The model portfolio s exposure to bonds is based on the underlying holdings of the mutual funds on page 1.

Understanding the short- and long-term behavior of asset classes may help investors manage their expectations and develop appropriate strategies. The lack of a pattern indicates that reliably predicting which asset classes will be the best or worst performers is difficult. Portfolios that combine asset classes in a diversified manner will seek to temper extreme returns. 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 S&P 500 Highest Return 56.28 33.16 34.54 35.97 39.82 8.78 79.02 28.07 17.95 18.63 38.82 32.00 4.48 21.31 37.75 Russell 2000 47.25 25.95 14.96 32.55 12.92 1.60 34.39 26.86 9.37 17.51 32.53 17.28 1.38 17.34 24.81 Russell 1000 Value 40.01 20.84 13.82 26.23 5.49-33.79 28.46 19.20 2.11 17.12 32.39 13.69 0.02 11.96 21.83 MSCI World ex USA (gross div.) 36.18 18.33 7.03 22.25 4.66-36.85 27.17 15.51 0.39 17.02 21.57 13.45-1.02 11.60 14.65 MSCI Emerging Markets (gross div.) 30.03 16.49 5.87 18.37 2.60-37.00 26.46 15.06 0.04 16.35 1.22 4.89-2.60 6.70 13.66 Dow Jones US Select REIT 28.69 10.88 4.91 15.80-0.17-39.20 19.69 12.44-4.18 16.00 0.02 0.02-3.83 6.68 12.25 One-Month US Treasury Bills 5.27 8.72 4.55 4.80-1.57-43.23 3.02 9.43-11.78 10.68-2.27-1.82-4.41 3.29 3.76 Lowest Long-Term Corporate Bonds Return 1.02 1.20 2.98 3.24-17.56-53.18 0.10 0.12-18.17 0.06-7.08-3.88-14.60 0.20 0.80 HISTORICAL PERSPECTIVES ON U.S. STOCKS AND TREASURY BONDS Investors seeking to build wealth for tomorrow must be willing to accept some fluctuations in the value of their investments today.

APPENDIX GENERAL DEFINITIONS Treasury securities are negotiable debt issued by the United States Department of the Treasury. government s full faith and credit and are exempt from state and local taxes. They are backed by the Corporate bonds are debt instruments issued by private corporations. Stock is the capital raised by a corporation through the issue of shares entitling holders to an ownership interest of the corporation. ANALYSIS METHODOLOGY The holdings based analysis looks through the mutual funds and examines the combined underlying securities of the funds in the portfolio, given the weights in the allocation. Companies are classified as small and large by computing breakpoints based on total market capitalization in each country or region. Within the US, large is defined as the largest 90% of market cap, and small is the smallest 10%. Within the non-us developed markets, large is the largest 87.5% of market cap, and small is the smallest 12.5%. Within emerging markets, large is the largest 85% of market cap, and small is the smallest 15%. Designations between value and growth are constructed in each country or region based on price to book ratios. Value is defined as the 30% of market cap with the lowest price to book ratios, and growth is the highest 70%. Bond s risk profile is generally determined by two factors: credit quality and maturity. The performance exhibits are generic and educational in nature, and do not pertain to your actual portfolio. The exhibits were designed to illustrate the relationship between risk and return, and the uncertainty of stocks relative to bonds. RISK DISCLOSURES Market risk is the risk that the value of an investment will decrease due to moves in market factors. Securities of small companies are often less liquid than those of large companies. As a result, small company stocks may fluctuate relatively more in price. Foreign securities prices may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or (b) less regulated or liquid securities markets. Investors holding these securities are also exposed to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S. dollar). Prices of fixed income securities tend to move in the opposite direction of interest rates. In general fixed income securities with longer maturities are more sensitive to price changes. Credit risk is the risk that the issuer of a security may be unable to make interest payments and/or repay the principal when due. Credit risk is greater for fixed income securities with ratings below investment grade. INDEX DEFINITION An index is a list of stocks provided by an index provider that tracks a given segment of the investment universe and serves as a benchmark against which performance and characteristics are measured. Indices are not available for direct investment; its performance does not reflect the expenses associated with the management of an actual portfolio. The DFA One-Year Fixed Income Portfolio and VA Short-Term Fixed Portfolio may have additional benchmarks listed in the prospectus that are not listed in this report. Please see the prospectus for information on each benchmark. RATINGS AGENCIES DEFINITION OF CREDIT RISK Credit rating agencies Moody's Investors Service and Standard & Poor's Corporation rate the credit quality of debt issues from governments, corporations, financial institutions, states, cities and municipalities. The ratings illustrated in this analysis reflect their independent opinions and assessment of the creditworthiness of the issuer, and its ability to make timely payments of principal and interest. The rating agencies assessment of the creditworthiness of the issuer may focus on the issuer's financial condition, credit history and other factors.

It includes those Russell 3000 companies with lower price-to-book ratios and lower forecasted growth values. It is reconstituted annually. Russell Microcap Index The Russell Microcap Index measures the performance of the microcap segment of the U.S. equity market. It makes up less than 3% of the U.S. equity market. It includes 1000 of the smallest securities in the small-cap Russell 2000 Index based on a combination of their market cap and current index membership and it includes the next 1,000 securities. It excludes lesserregulated OTC bulletin board securities and pink-sheet stocks due to their failure to meet national exchange listing requirements. It is reconstituted annually. The Russell indices are owned and maintained by Russell Investments. S&P 500 Index The S&P 500 is an index consisting of 500 stocks, which are weighted by market value. Its performance is thought to be representative of the stock market as a whole and provides a broad snapshot of the overall U.S. equity market. It is meant to reflect the risk/return characteristics of the large-cap universe. The index selects its companies based upon their market size, liquidity, and sector. Most of the companies in the index are solid mid cap or large cap corporations; thus, the effect of fluctuations in the price of a large firm's stock counts proportionately more than that of a smaller firm. Its inception date is 1957 and it is owned and maintained by Standard & Poor's, a division of McGraw-Hill. S&P Global REIT Index The index consists of all real estate investment trusts in both developed and emerging markets. The REITs in the index are primarily companies that invest in buildings, which are human occupied or used for storage. The index specifically excludes timber REITs, mortgage REITs and mortgage backed REITs. It is reconstituted annually. The date of base values is 12/31/97 and the inception date, which corresponds to the first date of data history, is 7/30/89.

Standardized Performance Data & Disclosures Performance data shown represents past performance. Past performance is no guarantee of future results, and current performance may be higher or lower than the performance shown. The investment return and principal value of an investment will fluctuate so that an investor s shares, when redeemed, may be worth more or less than their original cost. To obtain performance data current to the most recent month end, access our website at www.dimensional.com. Consider the investment objectives, risks, and charges and expenses of the Dimensional funds carefully before investing. For this and other information about the Dimensional funds, please read the prospectus carefully before investing. Prospectuses are available by calling Dimensional Fund Advisors collect at (512) 306 7400 or at www.dimensional.com. Dimensional funds are distributed by DFA Securities LLC. Dimensional Fund Advisors LP is an investment advisor registered with the Securities and Exchange Commission. Risks include loss of principal and fluctuating value. Investment value will fluctuate, and shares, when redeemed, may be worth more or less than original cost. Small and micro cap securities are subject to greater volatility than those in other asset categories. International and emerging markets investing involves special risks such as currency fluctuation and political instability. Investing in emerging markets may accentuate these risks. Sector-specific investments focus on a specific segment of the market, which can increase investment risks. Fixed income securities are subject to increased loss of principal during periods of rising interest rates. Fixed income investments are subject to various other risks, including changes in credit quality, liquidity, prepayments, call risk and other factors. Municipal securities are subject to the risks of adverse economic and regulatory changes in their issuing states. Real estate investment risks include changes in real estate values and property taxes, interest rates, cash flow of underlying real estate assets, supply and demand, and the management skill and creditworthiness of the issuer. Sustainability funds use environmental and social screens that may limit investment opportunities for the fund. Commodities include increased risks, such as political, economic, and currency instability, and may not be suitable for all investors. The Portfolio may be more volatile than a diversified fund because the Portfolio invests in a smaller number of issuers and commodity sectors. The fund prospectuses contain more information about investment risks.
