This is the value of any non-negotiable contracts that represent the receipt of funds available for later withdrawal. 

It includes: 
account balances of banks, non-bank ADIs and registered financial corporations (including transaction deposits, fixed-term deposits and other non-transaction deposits); 
purchased payment facilities such as smart cards and electronic cash; and 
non-negotiable certificates of deposit.
It excludes: 
holdings of physical currency (holdings of notes and coins); and 
negotiable certificates of deposit (a type of debt security); 
payables due to counterparties arising from the first leg of a repurchase agreement; 
commercial paper; 
arranged overdrafts.  These are generally an agreed arrangement between a lender and a borrower to extend credit when the balance in an attached transaction account falls below zero; and 
unarranged overdrafts.  These refer to the situation when a transaction account holder withdraws an amount greater than the balance of the account leaving a negative balance. The lender usually charges an overdrawn account fee as well as interest on the negative balance, and usually requires the account holder to restore the account's positive balance.
