All I know is that Ameritrade and the Transfer Agent made it logistically impossible [plus fee/cost prohibitive] for me to exchange shares before the extension, so I just bought 5K outright. Plus adding a ton more XTRN in the meantime -- I only had 550K pre-June xtrn shares in any case [bearing in mind only pre-Junes could be exchanged].
W/ xree @ .15 exch rate is approx .0005; and at .25 it's .0008 so.....
