Target Date future plans

[shipwreckedandalone]

 What is the average disposition for TD funds that have passed?  For example TD 2010 funds. Is the plan to continue listing forever?  
Any past examples ?  Is liquidation a consideration?  How are these being handled? 

 It seems like i remember reading in one fund family that the asset allocation continues to shift pass the TD until a certain limit allocation is reached and at that point freezes AA forever. 

If fund families do nothing, then the number of these type funds (passed TD) will grow resulting in many funds with different dates but same asset allocations (for new shareholders) thus incentive to discontinue operations or merge???

I'm most familiar with Vanguard whose funds merge into Vanguard Target Retirement Income (VTINX) approximately 7 years after reaching the target date. So far in the series, TD2005 and TD2010 have merged into VTINX, TD2015 (VTXVX) should sometime this year. Vanguard Retirement Income has a set asset allocation of 30/70.

Excellent answer.  Thanks. It looks like Schwab uses a 25 year glide path after target date is reached on the fund I am looking at with slow-ish equity runoff.
