A considerable amount of work was completed by CCMA members between 1999 and 2004 with respect to shortening the settlement cycle to T+1. The attacks of 9/11 changed the American and Canadian objective to improving straight-through processing as a precursor to shortening the settlement cycle. Here you will find analyses and white papers done at the time that may include information still useful now to shortening the settlement cycle.
