RE:RE:What happens on maturityyou have to go on the website and read the prospectus and marketing sheet. If they aren't extended, then it will be winded down or maybe converted or something else, if you read the info it sasys there. the market price impact for any of those options is probably very different. also the mechanics of the security are complex and have tax implaications if held in non-reg account. Look at some of my old posts, i explain in detail. they are paying the distribution by selling units basically and some call writing, since all of the portfolio income goes to the pref holders. You can see the distributions are almost all return of capital, not dividend income. ROC isn't taxed at distribution, but your cost basis has to be adjusted lower by that amount (they are returnung the capital you put in, hence the term ROC, non-taxable). Read the prospectus
