it's possible, but in that document it specifically states that the only other entity besides what's listed who owns more than 3.5% is frederick jones.
if you're breaking it up based on all indirect stakes in delfin being included in the 30.7% of fairwood's ownership of delfin, then i get 14.4% which is unaccounted for.
i'm considering all indirect ownership of delfin through fairwood as being included in the 30.7%, not on top of the 30.7%.
