Planning. It's what advisors do -- except, apparently, for themselves. When it comes to their own eventual exit from the business, how prepared are they? Not very, according to anxious industry-watchers. And either that will have to change, or firms may start disappearing as their principals age out of the profession.

And a report from Cerulli finds that 22 percent of advisors planning to retire in the next 10 years have no plan at all. The gallery above shows 7 reasons you might want to get started with succession planning.
