## Questions

### Who runs investment decisions at SEI?

Alfred P. West Jr., the founder, remains chairman and CEO. Investment decisions are managed by a combination of internal portfolio managers and outsourced CIO teams, with SEI's Investment Management Unit overseeing asset-allocation and manager selection for its funds.

### How does SEI source proprietary deal flow?

SEI's scale as a technology provider to the wealth management industry gives it unique data on advisor and investor behavior. It also leverages relationships with alternative managers like Blackstone to access private deals, though its primary sourcing remains through its own manager research and due diligence teams.

### Does SEI participate in fund commitments or only direct deals?

SEI does both. It commits capital to external funds as part of its managed-account strategies and also makes direct investments through its private credit and infrastructure vehicles. The firm is known for its fund-of-funds approach in alternatives.

### What investment stages does SEI typically target?

SEI targets a broad range from mid-market private credit to large-cap infrastructure, with a focus on income-producing assets. Its hedge fund exposure spans multi-strategy and event-driven funds, while private credit focuses on direct lending to established middle-market companies.

### Which sectors does SEI explicitly avoid?

SEI does not publicly publish a list of excluded sectors. However, its private credit funds tend to avoid early-stage venture, commodity speculation, and pure-play crypto exposures based on reported portfolio compositions.
