I generally stay away from callable CDs, Smart Notes, etc. most of the callable long term issues that I purchased in the early-mid 2000's were eventually called.
I do have a couple of Notes and Cd's which are not callable laddered to 2024.
My only concern regarding any fixed income product purchased via Fidelity is their disclaimer "that their fixed income product is designed for the long term," and their fixed income staff have let me know that their fixed products are difficult to sell on the secondary market.
With this in mind, I try to keep my ladder within 10 years.
