## Questions

### Who runs investment decisions at Boston Common Asset Management?

Founder Geeta Aiyer serves as President and leads the firm's investment strategy alongside a team of portfolio managers and analysts. The firm operates as an employee-owned partnership, with investment decisions made collaboratively by portfolio managers who also conduct direct corporate engagement on ESG issues.

### How does Boston Common Asset Management approach shareholder engagement?

The firm treats proxy voting and direct corporate dialogue as integral components of its investment process, not separate stewardship functions. Portfolio managers and analysts conduct engagement themselves, filing shareholder resolutions, pressing management on climate disclosure, board diversity, and labor practices, and participating in collaborative investor initiatives. This approach reflects founder Geeta Aiyer's conviction that active ownership can reshape corporate behavior.

### Is Boston Common Asset Management an ESG-only manager?

No. The firm runs concentrated, bottom-up equity portfolios that apply ESG integration as part of fundamental financial analysis rather than screening out entire sectors. The investment team looks for companies where improving sustainability practices overlap with undervalued financial performance, targeting long-term capital appreciation through active ownership.

### What investment strategies does the firm offer?

Boston Common manages concentrated long-only equity strategies across international, global, and US mandates, all incorporating integrated ESG analysis and active shareholder engagement. The firm does not run passive, fixed-income, or private-market funds; its focus remains exclusively on listed equities where engagement and proxy voting can influence corporate behavior.

### How is Boston Common Asset Management owned and governed?

The firm is an independent, employee-owned partnership certified as a women-owned business by WBENC. Women hold a majority of both equity and senior leadership positions, a structural feature that predates and remains uncommon within institutional asset management.
