BBMRX Investment Objective and Strategy

BBH Select Series Mid Cap Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by BBH Trust.

Investment objective

Each Acquiring Fund has the same investment objective as its corresponding Target Fund. Each Fund seeks to provide investors with long -term growth of capital. The investment objective of each Fund may be changed by the Board without shareholder approval.

Principal investment strategy

Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in publicly traded mid capitalization (mid cap) equity securities. Domestic securities include companies that are incorporated or headquartered in the U.S. Such securities may be issued by domestic or foreign issuers. The Fund may invest in the securities of foreign issuers both directly and in the form of depository receipts, including both sponsored and unsponsored American Depository Receipts (ADRs) and Global Depository Receipts (GDRs), each of which represent an interest in foreign securities. Securities of foreign issuers, or foreign securities, include companies that are neither incorporated nor headquartered in the U.S. The Fund primarily seeks to buy common stock and may also invest in preferred stock.

The Fund may also invest in large cap and small cap publicly traded equity securities. From time to time the Fund may invest in shares of companies through new issues or initial public offerings (IPOs). Subject to applicable statutory and regulatory limitations, the Fund may invest in shares of other investment companies, consisting of mutual funds and exchange -traded funds (ETFs). The Fund may also purchase other securities with equity characteristics, including securities convertible into common stock. Brown Brothers Harriman & Co. (BBH&Co.), through a separately identifiable department (Investment Adviser), considers mid cap securities to be securities that at the time of purchase have a market capitalization within the range of companies included in the Russell Midcap Index. The Funds strategy is based on fundamental business analysis and a long -term orientation.

The Investment Adviser selects companies based on their qualitative merits, competitive profile and prospective value creation potential. The Fund follows a buy and own approach that does not make use of short -term trades in pursuit of small gains. The Investment Adviser believes that its long -term orientation can benefit the Funds net performance results. Investments may be sold if they appreciate to levels at or near the higher end of the Investment Advisers estimated ranges of intrinsic value. The Fund is non -diversified and may invest a greater percentage of its assets in a particular issuer than would a diversified fund.
