As part of our overall plan we have some CDs, just rolling over every seven years. Put our IRA funds in every year for nine years, now just letting it ride and rollover until retirement. We also have bonds in 401k accounts, and some other CDs in taxable that is about 2% of our allocation. We have not fully worked out the cash streams yet for bridging to SS. We have work pensions that have an option to pay more until SS age. Haven't done any calculations yet, but need to in about five years.
