DTCC's Corporate Actions Transformation Initiative


The DTCC Corporate Actions Transformation initiative is a multi-year project which represents a major shift in the way corporate actions are communicated to clients. Benefits include increased automation and ease of use, which helps firms reduce risk, enhance efficiencies and drive down costs related to corporate actions processing.


The transition to ISO 20022 messaging and a new web-based user interface, called “CA Web”, are part of DTCC’s overall corporate actions transformation that will result in the replacement of the many files and legacy platforms that have evolved over the years.

The new CA Web has already replaced PTS/PBS functionality associated with distributions announcements, entitlements, instructions, allocations and adjustments, and will eventually encompass redemptions and reorganizations as well. ISO 20022 messaging will serve as the replacement for DTC’s legacy “CCF” corporate action files.

In order to deliver the CA Web and ISO 20022 messaging to clients, DTC changed the operative data model which utilized numeric function codes to represent different corporate action events, options and payouts. In place of the function codes, DTC now communicates information using a single-event structure, with events being represented as they are known in the market.
