I'm looking into rolling my 401K from old job into an IRA. While researching a traditional IRA account at Schwab and found the following:

"You may make contributions to your Rollover IRA. However, in doing so, you may forfeit your opportunity to roll over your assets into a new employer-sponsored retirement plan. This includes cash contributions, combining an existing IRA with your Rollover IRA and even a 401(k) or 403(b) payout."

Does anyone know under what conditions I would forfeit said opportunities?
