It didn’t take long for former Vanguard chairman Jack Brennan to land at least one lucrative gig after handing over the reins to Bill McNabb at the beginning of the year. In February, Brennan joined the board of LPL Investment Holdings, the nation’s largest independent-contractor broker-dealer. LPL reportedly has some 12,000 brokers under its umbrella, making it one of the largest brokerages in the country.

Brennan’s timing was admirable. LPL is headed for an IPO any day now. Brennan owns or has options on 22,136 shares. While SEC filings indicate he has no intention of selling shares at the IPO, an offering at the $27 to $30 per share estimated opening price will mean a tidy addition to his net worth of between $597,672 and $664,080. While this hardly matches the millions he took home while at Vanguard, it isn’t a bad windfall for his first year in “retirement.”

It may seem strange that an executive whose entire career was spent in the anti-broker world of no-load mutual funds would be involved with a company like LPL. But Brennan is also a governor of FINRA, the Financial Industry Regulatory Authority, the country’s largest regulator of securities firms.

And Brennan isn’t the only LPL board member with no-load experience. Jim Riepe, former chairman of T. Rowe Price Mutual Funds and vice-chairman of T. Rowe Price Group, has been a member of the LPL board since 2008. (He was also a member of FINRA’s governing board, but is no longer.) Riepe currently owns, or has options on 90,567 shares which means his holdings could be worth between $2.4 million and $2.7 million at the IPO.

Nice work, if you can get it.
