buying the entire bond or stock issue a company wants to sell at an agreed discount.
Explanation:
An investment-banking firm underwrites a new issue of stocks and bonds by buying the entire bond or stock issue a company wants to sell at an agreed discount.
Underwriting can be defined as the process through which an individual or organization assumes a financial risk at an appropriate and agreed fee.
In order to underwrite a new issue of securities such as bonds or stocks, the investment-banking firm buys the entire securities that the issuer is willing to sell at an agreed discount.
