A equivocal, as Brasília has decided against limiting the participation of private companies in all oil production.
B undesirable, since the government will definitely eliminate all concession contracts with foreign companies.
C troublesome, since the government task force has decided that private operators need not distribute revenues from sub-salt production.
D unnecessary, due to the concessions to be denied to seven international companies for the development of the sub-salt region.
E unresolved, because the Brazilian government is still unsure about the degree of participation that private partners should have in this new business.
