UPDATE: Hi all and sorry this has taken so long.
I received a list of SILVER Asset holders / number of assets held and respective btc payment addresses from glbse a few days ago. As of tomorrow (13 Dec 2012) it will have been 11 weeks since GLBSE shut down without notice. I have just paid out interest for that period and principal to all SILVER Asset holders I know of. The interest was calculated at 0.9% per week x 11. The principal calculated as 0.01 x Number of SILVER Assets (face/issue value x number of assets held). It was sent as one payment. The email from glbse indicated there may be others - any others I do receive will be paid out accordingly. NO interest will be payable beyond the current week. If I get time I will send a closing statement via email to each former SILVER Asset holder.
Thanks again to those who held SILVER Assets.
