6.6.1 Bank Overdrafts
A bank overdraft is one of the most common forms of short-term finance. It is really a loan arrangement whereby a trading bank allows a business (grants an overdraft facility) to make payments from its current banking account and put the account into 'debit' up to an agreed limit. A bank overdraft is part of working capital and is reported in the position statement as a current liability.
It is a flexible source of finance as it fluctuates according to the firm's needs and the business can pay in or withdraw cash when convenient. But it attracts a relatively high interest rate so it should only be used until the normal trading cycle eliminates the temporary cash shortfall.
The overdraft interest rate depends on:
- The bargaining position of the customer (long standing customers or large public companies can negotiate a lower rate)
- The current and expected future cash flow position of the customer
- The security held by the bank for the overdraft (a business may be required to pledge assets as security).
Secured overdrafts have lower interest rates, but banks charge other fees on all overdrafts, such as service fees and 'limit exceeded' fees.
In theory bank overdrafts are short-term. They are usually repayable at call at the bank's discretion. Trading banks regard an overdraft as a short-term loan made to finance temporary increases in a company's working capital.
In practice, some companies also use overdrafts to finance longer-term investments, and may regard large portions of their overdrafts as a permanent source of working capital suitable to finance the purchase of non-current assets. This is risky as the bank can call in the overdraft at any time and at short notice.
Two possible reasons why companies use large overdrafts are:
- as a precaution against unforeseen contingencies
- they can get cheaper finance through the inter-company loan market at call, and use the unused portion of their overdraft as 'security'
Companies that prepare good cash budgets can anticipate when an overdraft is needed, for what amount and for how long. The lending bank will often ask to see the forecast cash budget as evidence that the company has planned how to repay the overdraft.
