Investment objective & strategy

As of Oct. 29, 2025 · prospectus

Objective. The Brown Advisory Sustainable Bond Fund (the Fund) seeks to provide a competitive total return consistent with preservation of principal while giving special consideration to certain sustainable investment criteria.

Strategy. Under normal conditions, Brown Advisory LLC (the Adviser) seeks to achieve the Funds investment objective by investing at least 80% of the value of its net assets (plus any borrowings for investment purposes) in either fixed income securities of issuers that satisfy the Funds sustainable investment criteria or in securities where the use of the proceeds satisfy the Funds sustainable investment criteria, together, the Investment Criteria for the Fund. This 80% investment policy is non-fundamental and may be changed without the vote of shareholders. Shareholders will receive 60 days prior written notice of any changes to the Funds 80% investment policy. The Fund may invest in corporate fixed income securities, mortgage-backed and asset-backed securities, U.S Government securities and securities issued … Under normal conditions, Brown Advisory LLC (the Adviser) seeks to achieve the Funds investment objective by investing at least 80% of the value of its net assets (plus any borrowings for investment purposes) in either fixed income securities of issuers that satisfy the Funds sustainable investment criteria or in securities where the use of the proceeds satisfy the Funds sustainable investment criteria, together, the Investment Criteria for the Fund. This 80% investment policy is non-fundamental and may be changed without the vote of shareholders. Shareholders will receive 60 days prior written notice of any changes to the Funds 80% investment policy. The Fund may invest in corporate fixed income securities, mortgage-backed and asset-backed securities, U.S Government securities and securities issued by foreign entities including foreign-sponsored governmental agencies. The fixed income securities in which the Fund may invest may also include municipal securities issued by states, U.S. territories and possessions, general obligation securities and revenue securities. The foregoing may include municipal lease obligations and insured municipal securities. The Fund may also invest in other investment companies that invest in similar fixed income securities and the Fund may count such holdings towards the Funds 80% investment policy. The Fund may also engage in To Be Announced transactions. Certain of the fixed income securities that the Fund may invest in are often commonly referred to as labeled bonds. Labeled bonds include, but are not limited to, Green Bonds, Social Bonds, Sustainability Bonds, or Sustainability-Linked Bonds. The Fund invests in fixed income securities that primarily have a maturity that is between 0 and 30 years and are rated in the top four rating categories of a Nationally Recognized Statistical Rating Organization, or unrated and deemed to be of comparable quality by the Adviser. Under normal circumstances, the Funds portfolio will have an average dollar weighted maturity between 6 and 11 years and an average duration of 3 to 7 years. Duration is a measurement of price sensitivity to interest rate changes. The Fund may invest up to 20% of its assets in high-yield securities (junk bonds), which are speculative in nature. The Fund may invest in securities denominated in non-U.S. currencies. The Fund may also invest in bank loans. The Fund may invest in derivatives instruments, such as options, currency forwards, futures contracts, including interest rate futures, options on futures, interest rate swaps and credit default swaps. These investments will typically be made for investment purposes consistent with the Funds investment objective and may also be used to mitigate or hedge risks within the portfolio or for the temporary investment of cash balances. These positions may also be used to manage interest rate risk or to create synthetic exposure to particular credits. Investments in derivatives may be counted towards the Funds 80% investment policy if they have economic characteristics similar to the other investments that are included in the Funds 80% investment policy. The Fund intends to use the mark-to-market value of such derivatives for purposes of complying with the Funds 80% investment policy. The Adviser utilizes sustainable investment analysis in connection with the Fund's investments in fixed income securities. As part of the research approach, the Adviser has a process to integrate, identify and consider the sustainable investment related risks and opportunities using a sustainable investment research assessment. The assessment may be conducted at the sector, issuer, shelf or security level. Not every investment will be covered at the issuer or security level. The Fund has access to this research and considers relevant sustainability issues. However, at the Advisers discretion, the Fund is permitted to make an investment without a written sustainable investment research assessment on file at the time of purchase, as long as the Adviser believes the security meets the Funds sustainable investment criteria. The Funds sustainable investment criteria considers many factors including, but not limited to, any one or more of the following: clean and renewable energy, climate change and water conservation, waste management, natural resource stewardship, innovative efficiency solutions, labor management, community relations, supply chain management, customer well-being, stewardship of debt and capital, board governance and transparency, and business ethics. The outcomes of the Advisers research may result in positive environmental and social impacts. While not a thematic fund, the nature of the Advisers research considers sustainable investment themes, such as any one or more of sustainable technology innovation, accessibility of essential services like healthcare, financial inclusion, and climate mitigation. The Adviser pursues strategic engagement with issuers and other stakeholders in an effort to enhance due diligence and monitor the investment thesis. In order to respond to adverse market, economic, political, or other conditions, the Fund may assume a temporary defensive position that is inconsistent with its investment objective and principal investment strategy and invest without limit in cash and prime quality cash equivalents such as prime commercial paper and other money market instruments. A defensive position, taken at the wrong time, may have an adverse impact on the Funds performance. The Fund may be unable to achieve its investment objective during the employment of a temporary defensive measure.
