²»Á¼Ñо¿Ëù¹Ù·½

The financial modeling methodology used by the SSG for RMBS and CMBS is described in Part Seven of the Purposes and Procedures Manual of the ²»Á¼Ñо¿Ëù¹Ù·½ Investment Analysis Office.

Each financially modeled Non-Legacy Security (RMBS and CMBS that closed on or after January 1, 2013*) will receive a single ²»Á¼Ñо¿Ëù¹Ù·½ Designation and ²»Á¼Ñо¿Ëù¹Ù·½ Designation category rather than Price Grids (breakpoints). Price Grids will continue to be provided for financially modelled RMBS and CMBS Legacy Securities (RMBS and CMBS that closed prior to January 1, 2013).

• Financial modeling results in the generation of probability weighted net present values, which we call Price Grids.

  For further detail please read the Breakpoint Calculation Overview (Old file but same concept)

• Price Grids are CUSIP specific price matrices containing 19 price breakpoints; i.e., each price corresponding to a specific ²»Á¼Ñо¿Ëù¹Ù·½ Designation category.
  2022 Breakpoints will match to ²»Á¼Ñо¿Ëù¹Ù·½ Designations with a modifier as explained in the following document,

  Please refer to a recent amendment to Part 4 of the P&P Manual and the Modeling Update meeting material prepared for the Valuation of Securities (E) Task Force:

• Part 4 of the P&P Manual Update Amendment to the P&P Manual updating Part Four for ²»Á¼Ñо¿Ëù¹Ù·½ designation categories and additional price points 

• Each breakpoint on a Price Grid is the minimum price point (Book Adjusted Carrying Value) that tips the ²»Á¼Ñо¿Ëù¹Ù·½ Designation for the RMBS/CMBS CUSIP into the next ²»Á¼Ñо¿Ëù¹Ù·½ Designation category.
• Two Price Grids are generated for every CUSIP: one for insurance companies that maintain an asset valuation reserve and another for insurance companies that do not.
• Not all securities submitted for consideration will be modeled. Reasons for why they were not modeled can be found on the RMBS/CMBS Securities ListingÌý±è²¹²µ±ð.

Insurance companies use the Prices Grids in accordance with instructions contained in Loan Backed and Structured Securities, in the ²»Á¼Ñо¿Ëù¹Ù·½ Accounting Practices and Procedures Manual.

• The insurance company first derives a final ²»Á¼Ñо¿Ëù¹Ù·½ Designation for the RMBS or CMBS and they then use that final ²»Á¼Ñо¿Ëù¹Ù·½ Designation to derive the risk-based capital (RBC) applicable to the RMBS or CMBS.
