Hi Alan,
I guess it depends how much you paid, and why you bought them.
SCFHA are a cheap way to get into floating-rate fixed interest.
I believe that we will have "high" inflation (+5%) in the short to medium term so the annual rate reset is an attractive feature.
The downside of SCFHA is the risk, but I suspect that the receivers will find more than 35c in the dollar should the time come.
Overall, I rather suspect that the SCFHA's (and many other HA's, come to that) were bought by people who had no idea what they were buying.
If you prefer fixed to annual resets, some of the BNZIS series are quite attractive on yield.
