The Securities Origination, Underwriting and Reliable Corporate action Environment (UW SOURCE) online platform gives you access to Underwriting functions. UW SOURCE streamlines the underwriting process to generate further efficiencies, reduce costs and provide greater flexibility. UW SOURCE improves the underwriting processing in the following functional areas: Underwriting Offering Activity Processing; Eligibility Processing (including Quality Assurance Processing); and Security Eligibility Determination.
UW SOURCE allows a user to transmit key data elements electronically via three submission options:
- Access the templates onscreen and populate the required data manually.
- Access the system and upload an Excel spreadsheet template.
- Use a computer to compute autofeed transmission.
Through UW SOURCE users can then monitor an issue's progress throughout the underwriting process and track the approval, processing, packaging and closing status. There is no cost to register for UW SOURCE but users must be DTC participants or correspondents.
