Broker-dealer affiliated. The firm is affiliated with a broker-dealer (Item 7.A(1)), at least half of its advisory staff are registered representatives of a broker-dealer (Item 5.B(2) against 5.B(1)), and its advisers manage less than $100 million each on average (5.F(2)(c) over 5.B(1)), the pattern of a broker-dealer's advisory arm rather than an adviser that owns a small broker-dealer. It is ranked among all wealth firms, the directory's view that includes wirehouses and broker-dealer firms, not in the main lists of independent RIAs. How firms are classed.

Growth rates come from the SEC's yearly snapshots and are left blank when the years are not comparable.
