A bank may have substantial sums in off-balance-sheet accounts, and the distinction between these accounts may not seem obvious. For example, when a bank has a customer who deposits $1 million in a regular bank deposit account, the bank has a $1 million liability. If the customer chooses to transfer the deposit to a money market mutual fund account sponsored by the same bank, the $1 million would not be a liability of the bank, but an amount held in trust for the client (formally as shares or units in a form of collective fund). If the funds are used to purchase stock, the stock is similarly not owned by the bank, and do not appear as an asset or liability of the bank. If the client subsequently sells the stock and deposits the proceeds in a regular bank account, these would now again appear as a liability of the bank. As an example, UBS has CHF 60.31 billion
Undrawn irrevocable credit facilities off its balance sheet in 2008 (US$60.37 billion.) Citibank has US$960 billion in off-balance-sheet assets in 2010, which amounts to 6% of the
GDP of the United States. ==References==
