Subject: Re: Portfolio for a 90 year old
If you want to defer it all, you could buy TIPS STRIPS. Same yield to maturity but no coupons along the way. I've heard they aren't too hard to buy.

True, there are no coupons but there is imputed interest annually.

I'm not sure who benefits from STRIPS. They are based on other Treasury securities, so wouldn't they have lower yield after the financial institution takes its cut?

The only small benefit I see is not having the annoyance of investing the coupons. What have I missed?
