ASICMINER shares have the privilege of getting all net profits till 0.1BTC/share from the day when dividends began to be paid.
I don't get this part. Does it mean that once 0.1BTC dividends per share have been given, there won't be more dividends?
That formulation means that after 0.1BTC has been paid in dividends, Bitfountain (major shareholder of Asicminer) will also get it's portion of dividends. Until 0.1 all dividends (100%) have been paid to minor shareholders only. Anyhow, it doesn't matter anymore, dividends reached 0.6BTC already.
