Figures shown are past results and are not predictive of results in future periods. Current and future results may be lower or higher than those shown. Investing for short periods makes losses more likely. Prices and returns will vary, so investors may lose money. View current mutual fund SEC yields.
Active Share is determined by (1) differences in stock weightings between the fund and the fund's primary benchmark shown in the prospectus (2) inclusion of stocks outside of the benchmark, and (3) exclusion of stocks in the benchmark.

Active Share is neither a predictor of future returns nor a measure of manager skill. Since it measures the difference between a fund's holdings and its benchmark, it could be used in conjunction with other indicators as a measure of portfolio risk or to compare the management fees charged by actively managed funds. While an active share greater than zero is needed to provide returns above the benchmark, there is no indication a particular level of active share has resulted in higher returns than the fund's index. A fund's active share can change significantly over time, thus measuring a single point in time may not be reflective of longer periods.

The Capital Group portfolios are managed by multiple portfolio managers who invest based on their highest convictions. The result is a diversified portfolio based on the collection of managers' individual investment decisions. A fund's active share is the product of this process and is not comparable to the active share produced by a fund managed by an individual or a committee of investors. The funds are managed based on their investment objectives and strategies described in the prospectus; managing to active share is not part of any fund's strategy.
Investments are not FDIC-insured, nor are they deposits of or guaranteed by a bank or any other entity, so they may lose value.
Investors should carefully consider investment objectives, risks, charges and expenses. This and other important information is contained in the mutual fund prospectuses and/or summary prospectuses, which can be obtained from a financial professional and should be read carefully before investing.
Nondiversified funds have the ability to invest a larger percentage of assets in the securities of a smaller number of issuers than a diversified fund. As a result, poor results by a single issuer could adversely affect fund results more than if the fund invested in a larger number of issuers. See the applicable prospectus for details.
Smaller company stocks entail additional risks, and they can fluctuate in price more than larger company stocks.
Capital Group offers some funds in a range of share classes designed to meet the needs of retirement plan sponsors and participants. The different share classes incorporate varying levels of financial professional compensation and service provider payments. Because Class R-6 shares do not include any recordkeeping payments, expenses are lower and results are higher. Other share classes that include recordkeeping costs have higher expenses and lower results than Class R-6.
There have been periods when the results lagged the index(es) and/or average(s). The indexes are unmanaged and, therefore, have no expenses. Investors cannot invest directly in an index.

The Morningstar Rating™ for funds, or "star rating", is calculated for managed products (including mutual funds, variable annuity and variable life subaccounts, exchange-traded funds, closed-end funds, and separate accounts) with at least a three-year history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product's monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance. The Morningstar Rating does not include any adjustment for sales loads. The top 10% of products in each product category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its three-, five-, and 10-year (if applicable) Morningstar Rating metrics. The weights are: 100% three-year rating for 36-59 months of total returns, 60% five-year rating/40% three-year rating for 60-119 months of total returns, and 50% 10-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns. While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods. Past results are not a guarantee of results in future periods. The Morningstar Ratings are based on the share classes of each underlying fund held by the series; other underlying fund share classes may have different performance characteristics.
10.
Accrued income and the timing of its settlement, as well as classification of convertible bonds as debt or equity, can cause slight variations in the balances displayed in different portfolio composition breakdowns.

Includes cash, short-term securities, other assets less liabilities, accruals, derivatives and forwards. It may also include investments in money market or similar funds managed by the investment adviser or its affiliates that are not offered to the public.
12.
The Morningstar Ownership Zone™ provides detail about a portfolio's equity investment style by showing the range of stock sizes and styles. A portfolio's Ownership Zone™ is derived by plotting each stock in the fund's portfolio within the proprietary Morningstar Style Box™. The shaded area represents the center 75% of the fund's assets, and it provides an intuitive visual representation of the area of the market in which the fund invests. A "centroid" plot in the middle of the Ownership Zone represents the weighted average of all the fund's holdings. A fund that is concentrated will have a small ownership zone relative to the area of the style box, and broadly diversified fund will have an ownership zone that stretches across many sizes and style. Over a period of time, the shape and location of a fund's ownership zone may vary.
13.
Figures include convertible securities. The equity breakdown by revenue reflects the portfolio's publicly traded equity holdings and excludes cash (and fixed income securities, if applicable). Underlying revenue data were compiled by MSCI and account for disparities in the way companies report their revenues across geographic segments. MSCI breaks out each company's reported revenues into country-by-country estimates. MSCI provides revenue data figures based on a proprietary, standardized model. Revenue exposure at the portfolio and index level was calculated by using FactSet, which takes these company revenue exposures and multiplies by the company's weighting in the portfolio and index. In this breakdown, Israel has been included in Europe.
