Project Name: TDAF (TD Auto Finance)

 

Basel/Lending Data Mart (BLDM) Enhancements is considered a ‘sub project’ under the TDAF US Risk Management Integration Project umbrella.  The key deliverables of the BLDM Enhancements sub-project are to establish on-going data feeds and provide Historical Data Capture data set from the TD Auto Finance (TDAF) systems to the Basel/Lending Data Mart (BLDM) and then RRVA ELM (Expected Loss Methodology) environment to support US Retail Basel reporting and analysis.  The existing US Basel data fields will be used for incorporation of the TDAF data into the US Basel program.  US Retail Risk Management (US RRM) reporting and analysis will use the TDAF data in the BLDM and ultimately have the necessary data elements in the Retail Risk Universe in order to perform the Monthly Delinquency (DLQ) Report and Quarterly Vintage Report. All of the current data elements and current calculations identified as part of the interim “OCC file” (provided from TDAF to Retail Risk) will be delivered into the BLDM.  This will allow for the elimination of the interim OCC file that Retail Risk Management currently receives

 

It is the intent of this effort to ensure that as much as 60 months of loan performance data be retrieved and stored in a usable and meaningful way so as to enable TD Bank to bring the TDAF portfolio into Basel compliance.
