CSR sec non-CTP buckets
Reference for the CSR Sec non-CTP Buckets configuration file, which maps credit quality and sector to a securitization bucket (1-25) covering RMBS, CMBS, ABS, and CLO categories, and can auto-populate the Bucket field in sensitivity files.
When the SBM sensitivity files (Curvature, Delta, or Vega) omit the Bucket field, it is filled in from this CSR Sec non-CTP Buckets file. To take advantage of this, the buckets file must be loaded before (or at the same time as) the Curvature, Delta, or Vega file.
