15. CMO/ABS Actions from meeting The establishment of a working group by DTC to perform diagnostic work and produce data and detailed structure diagrams on various deal types, asset classes, and specific deal features that affect payment processing accuracy and timeliness. The group will need to document the current practices, data elements, and timeframes for all the known (or most prevalent) structures of each security type. This project will allow for the group to address various structural issues that contribute to the accuracy/timeliness problem and thus explore methods in remedying those problems.

16. CMO/ABS Actions from meeting – Cont’d The establishment of a working group to define the data, file format, and communication protocol standards for the information that flows between primary servicers and paying agents, to be defined by specific product types. The ensuing product may be able to bring standardization in the information/funds transfer from the primary servicers to the paying agent, thus increasing efficiency.

17. CMO/ABS Actions from meeting – Cont’d An investigation conducted by DTC to examine the nature of post-payable adjustments. Part of the issue will be to tackle how much of the accuracy problem can be solved by potentially modifying post payable date adjustment procedures by setting a time limit for adjustments. DTC will further categorize the adjustments it previously analyzed in its white paper by principal, interest and principal and interest adjustments and report back to the Task Force. There was discussion in the meeting of the effects of setting such a limit, especially with regard to principal adjustments.
