to explain the paper I owned was a bond - and the interest was not in % - but I think 10% after date X if the DOW was over ABC price on that date . These securities did not trade and fit in the category of structured products (not in an annuity)
I was in the profit and 30% above the DOW level that would have made me lose money
But LEHMAN Went under
And I learned the hard way that UNSECURED but SR BONDS are not 100% repaid on 11
Lots of lessons and BIG WINS over 25 or whatever years with small parts of my money (GM Preferred Stock the Day the UNION said it wanted to trade them for immediate cash and give up that % of ownership in the reorg on the table)
