Line of credit

Commercial paper is a lower cost alternative to a line of credit with a bank. Once a business becomes established, and builds a high credit rating, it is often cheaper to draw on a commercial paper than on a bank line of credit. Nevertheless, many companies still maintain bank lines of credit as a "backup". Banks often charge fees for the amount of the line of the credit that does not have a balance. While these fees may seem like pure profit for banks, in some cases companies in serious trouble may not be able to repay the loan resulting in a loss for the banks.
