The Morningstar Medalist Rating is the summary expression of Morningstar's forward-looking analysis of investment strategies as offered via specific vehicles using a rating scale of Gold, Silver, Bronze, Neutral, and Negative. The Medalist Ratings indicate which investments Morningstar believes are likely to outperform their Morningstar Category average on a risk-adjusted basis over time. Investment products are evaluated on three fundamental pillars (People, Parent, and Process) and the Medalist Rating Price Score, which forms the basis for Morningstar's conviction in those products' investment merits and determines the Medalist Rating they are assigned. Pillar ratings take the form of Low (-2), Below Average (-1), Average (0), Above Average (+1), and High (+2). Pillars may be evaluated via an analyst's qualitative assessment (either directly to a vehicle the analyst covers or indirectly when the pillar ratings of a covered vehicle are mapped to a related uncovered vehicle) or using algorithmic techniques. The cost of an investment product is evaluated using the Medalist Rating Price Score, which is a continuous score running from negative 2.5 to positive 2.5 based on the percentile rank of a vehicle's expense ratio within its Morningstar Category. Morningstar combines the pillar scores and Medalist Rating Price Score using predetermined weights for actively and passively managed vehicles to calculate a weighted score. The weighted score is then compared to a set of fixed numeric thresholds employed consistently across Morningstar Categories and regions, with separate thresholds for actively and passively managed investments. Rating thresholds are reviewed at least annually. Buffers and ratings caps are employed to prevent frequent ratings changes. When analysts directly cover a vehicle, they assign the fundamental pillar ratings based on their qualitative assessment, subject to the oversight of the Analyst Rating Committee, and monitor and reevaluate them approximately once a year. When vehicles are covered either indirectly by analysts or by algorithm, the ratings are assigned monthly. For more detailed information about the Medalist Ratings, including their methodology, please visit Morningstar's website for more information. The Morningstar Medalist Ratings are not statements of fact, nor are they credit or risk ratings. The Morningstar Medalist Rating (i) should not be used as the sole basis in evaluating an investment product, (ii) involves unknown risks and uncertainties which may cause expectations not to occur or to differ significantly from what was expected, (iii) is not guaranteed to be based on complete or accurate assumptions or models when determined algorithmically, (iv) involves the risk that return targets will not be met due to unforeseen changes in management, technology, economic development, interest rate development, operating and/or material costs, competitive pressure, supervisory law, exchange rates, tax rates, or political and social conditions, and (v) should not be considered an offer or solicitation to buy or sell the investment product. A change in the fundamental factors underlying the Morningstar Medalist Rating may result in the rating no longer being accurate. Analysts do not have any other material conflicts of interest at the time of publication. Users wishing to obtain further information should contact their local Morningstar office.

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.

Portfolios are managed, so holdings will change. Certain fixed income and/or cash and equivalents holdings may be held through mutual funds managed by the investment adviser or its affiliates that are not offered to the public.

Totals may not reconcile due to rounding and/or cash flows.

Investment results assume all distributions are reinvested and reflect applicable fees and expenses.

When applicable, results reflect fee waivers and/or expense reimbursements, without which they would have been lower and net expenses higher. For mutual funds, read details about how waivers and/or reimbursements affect the results for each fund. View results and yields without fee waiver and/or expense reimbursement.

Certain share classes were offered after the inception dates of some funds. Results for these shares prior to the dates of first sale are hypothetical based on the original share class results without a sales charge, adjusted for typical estimated expenses. 

• Class R-6 shares were first offered on 5/1/2009.

Results for certain funds with an inception date after the share class inception also include hypothetical returns because those funds' shares sold after the funds' date of first offering. Refer to dates of first sale and specific expense adjustment information.
