The share of an office's assets or revenue attached to one adviser as primary, read against the expected share of one over the number of advisers. High concentration with clients who have no second relationship is succession risk.
An adviser at 4 percent of the firm can be 45 percent of their office. The office loses the clients, so the office is the level.
A concentrated book is a successful one. The risk is the share of it with no second contact, and the list is those clients.
Assets and revenue with each adviser as primary, divided by the office or firm total, together with the share of those clients who have no second relationship at the firm.
One adviser holds $310 million of an office's $1.4 billion: 22 percent. Of her 140 clients, 118 have had no logged contact with anyone else at the firm in a year. If she leaves, most of that fifth is at risk.
Reported as a league table of top advisers, which reads as success. The risk is the second column, clients with a single relationship, and it is rarely shown.
