In the statement, the OFT stated that the fees charged by credit card issuers were comparable to the unauthorized overdraft fees charged by the banks. Many customers who had to pay unauthorized overdraft fees used this statement as a springboard to sue their banks to recover the fees. The terms and conditions for related and unrelated facilities are used to refer to capital financing conditions for short- or long-term agreements. In the case of a promised facility, the lender must pay money to the borrower as soon as the terms of the loan agreement are agreed. In return, the borrower pays the lender a commitment tax – a fee that must be paid to a lender on available but unused amounts and is calculated from time to time as a percentage of these unused funds. An overdraft occurs when the money is withdrawn from a bank account and the available balance is less than zero. In this situation, the account is classified as “debitable.” Where there is a pre-overdraft agreement with the account provider and the excessive amount is included within the authorized overdraft limit, interest is normally calculated at the agreed rate. If the negative balance exceeds the agreed terms, additional charges may be charged and higher interest rates. Bounce protection plans have superficial similarities to overdrafts and ad hoc overdraft coverage, but tend to operate under different rules. As with an overdraft line, the balance of the bounce protection plan may be visible as part of the client`s available balance, but reserves the right to refuse payment for an excess item, as in the case of traditional ad hoc coverage. Banks typically charge a one-time fee for each overdraft paid.
