Divedends received. 0.00066618 per "new" share.
I assume this was a baloon payment as we've all been locked to 100MH/s for a while now. So I'd assume this would be the back pay of "bonuses"which would essentially be the effective hash rate should our shares be uncapped.
LR tripled our contracts to account for the hashrate at the time. Which suggests he's been hashing with new equipment - and setting some or all of those proceeds aside - for a significant period of time, possibly since 8 March (the date of the supposed contract change). Of course we will never know for sure because LR doesn't disclose what he's hashing with, how much BTC he's taking in, what the overheads are, etc.
