[A Song of Ice and Fire] Who is the majority stakeholder of the Iron Bank of Braavos?

So the Iron Bank has some serious cash to throw around, and it's an institution that will exist long after the people who currently run it die, but surely there must be somebody who has the final say in decisions?

Who has the most share in the wealth of the Iron Bank, and who would be most affected if it were to shut down?

Members of the Bravosi Elite. There are thousands of keyholders in Bravos who own some share technically but most of them inherited that right and don't have controlling say. There is an actual "board" of sorts that is not publicly known made up of the major contributors who don't even necessarily count as keyholders (don't wear an iron key around there neck even) but who actual make the decisions and own most of the Bank's wealth.  

They would suffer the most if the Bank were somehow to fall but the chances of that are incredibly small, the Iron bank is one of the strongest most robust organizations on Planetos.
