FYI: As of February 2020, PIMCO's RealPath target-date funds will be no more. The company is shuttering the series, for the usual reason of poor sales. The funds were launched a decade ago but possess only a collective $140 million. Worse yet, they have suffered more than $30 million in outflows so far this year. You don't need to have majored in math to understand those consequences.
