I am 64 years of age. My Roth IRA is about to reach its 5-year holding period on 2010. Will opening a new Roth IRA account be subject to another 5-year holding period?

If you are opening a new Roth at another firm and transferring this account into it, then the answer is no since the new account take on the life span of the previous account. If you are opening another Roth at the same firm that you have the previous one, then yes. Alos, there is no real reason to open a new Roth at the same form for the contribution limit total is is the same for both accounts.
