Abstract: The systems and methods described herein provide Web based tools that allow a custodial bank or other institution to provide their security lending customers or prospective customers with tools for analyzing different risks/return scenarios. To this end, these Web-based systems may lead a security holder through a process wherein the security holder creates a profile that describes the different types of securities within their portfolio and describes the allocation of the security assets among different asset classes. The Web-based processes are capable of generating graphical images of the estimated earnings and certain risks present in a securities lending transaction, to thereby present to the security holder a visual representation of the information the holder needs to make an informed investment decision.
