In 1990, a Price Waterhouse audit of BCCI revealed an unaccountable loss of hundreds of millions of dollars. The bank approached Sheikh Zayed bin Sultan Al Nahyan, who made good the loss in exchange for an increased shareholding of 78%. Much of BCCI's documentation was then also transferred to Abu Dhabi. The audit also revealed numerous irregularities. Most seriously, BCCI had made a staggering $1.48 billion worth of loans to its own shareholders, who used BCCI stock as collateral.
The audit also confirmed what many Americans who had watched BCCI had long suspected--that BCCI secretly owned First American. When the Fed cleared the group of Arab investors to buy First American, it did so on condition that they supplement their personal funds with money borrowed from banks with no connection to BCCI. Contrary to that agreement, several stockholders had borrowed heavily from BCCI. Even more seriously, they pledged their First American stock as collateral, and when they didn't make interest payments BCCI took control of the shares. It was later estimated that in this manner, BCCI had ended up with 60 percent or more of First American's stock.

In 1982, 15 Middle Eastern investors bought Financial General Bankshares, a large bank holding company headquartered in Washington, D.C. All the investors were BCCI clients, but the Federal Reserve received assurances that BCCI would be in no way involved in the management of the company, which was renamed First American Bankshares. To alleviate regulators' concerns, Clark Clifford, an adviser to five presidents, was named First American's chairman. Clifford headed a board composed of himself and several other distinguished American citizens, including former United States Senator Stuart Symington. In truth, BCCI had been involved in the purchase of FGB/First American from the beginning. Abedi had been approached about buying it as early as 1977, but by this time BCCI's reputation was such that it could not hope to buy a bank on its own. Rather, it used the First American investors as nominees. Moreover, Clifford's law firm was retained as general counsel, and also handled most of BCCI's American legal work. BCCI was also heavily involved in First American personnel matters. The relationship between the two was so close that rumors spread BCCI was the real owner of First American.
