What this means for you
- It charges only as a percentage of the assets it manages. Ask about the fee schedule and any account minimum, which Form ADV Part 1 does not record.
- Most of its individual clients are high-net-worth, which on Form ADV means they meet the SEC’s qualified-client or qualified-purchaser test: broadly, more than $1 million managed by the adviser or a net worth above $2 million, with the thresholds indexed for inflation.
- It reports no disciplinary history on Form ADV.
Before you hire any adviser
Read the firm’s Form ADV Part 2 brochure on its SEC record: it sets out fees, minimums, conflicts of interest and who will manage your money. Ask whether the firm acts as a fiduciary for all of your accounts, how it is paid in total, and who holds your assets. Our guide to choosing a financial adviser lists the questions to ask.
