500 independent registered investment advisors and $10 billion held in more than 2,000 plans administered by 80 independent third-party administrators, the companies said.

The sale price was approximately $225 million cash plus acquired regulatory capital and a potential earn-out up to $100 million based on 12-month revenue targets, the companies said.
