## Questions

### How does Isthmus Partners construct client portfolios?

Isthmus builds portfolios from individual securities and fund vehicles, not packaged model portfolios. Public equity and fixed-income positions are selected directly by the firm's investment team. Private market allocations—venture, private equity, and real estate—are accessed through external fund commitments and co-investment structures rather than direct operating-company deals.

### Is there a parent bank or institution behind Isthmus Partners?

No. Isthmus Partners operates as an independent partnership, not as a division of a bank, trust company, or broker-dealer. This independent structure means the firm is not obligated to fill client portfolios with proprietary products or to route trades through an affiliated platform, distinguishing it from private wealth groups housed within regional banking organizations.

### What is the firm's approach to asset-allocation decisions?

Isthmus builds allocations around client-specific balance sheets rather than a single house view. The framework integrates taxable-bond management—particularly municipal portfolios—alongside equity and alternative sleeves, with an emphasis on after-tax return and capital preservation. This is a planning-first approach more common to a family-office practice than a product-centered advisory firm.
