**The section of the Summary Prospectus entitled "Management — Portfolio Managers" and the section of the Prospectus entitled "Fund Overview — Management — Portfolio Managers" are deleted in their entirety and replaced with the following:**

**The section of the Prospectus entitled "More Information About the Fund — Investment Process" is deleted in its entirety and replaced with the following:** 

**Investment Process.** Fund management seeks to identify long-term, structural investment themes that are reshaping the global economy. Within these themes, management looks to invest in fundamentally sound companies that have above-average return potential based on factors such as revenue and earnings growth, estimate revisions, profitability and relative value. The factors and the weight assigned to a factor may change depending on market conditions. The disciplined investment process uses bottom-up stock selection as the primary driver of returns, while incorporating quantitative tools to enhance decision-making. The Fund emphasizes large companies that exhibit above-average growth and accelerating earnings.

When constructing the portfolio, the Fund uses a quantitative, optimization-assisted process that considers the risk and factor profile of individual securities. This supports the portfolio managers in the construction of a portfolio that expresses the highest conviction stock-specific views while mitigating style and macro exposure.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

**The section of the Prospectus entitled "Management — Portfolio Managers" is deleted in its entirety and replaced with the following:**
