Here's the math: (at least it adds up...lol) NBL and PXD will both receive 15% (not 15% of ERHC's 25&30%'s) This amounts to a 60% carry fee for NBL and 50% for PXD. ERHE then has 10% left in B4 and 15% left in B2. The additional bid win in each block was 35% above preferential rights. ERHE receives 10% of that Gratis as payment for making it all happen. Bottom line.. 10%+.1*35%= 13.5% in B4 15%+.1*35%= 18.5% in B2 I have no more info than any of you....
