Pricing: The 2020 Structured Securities modeled data prices for CUSIPs held by insurers is $100 per CMBS CUSIP and $70 per RMBS CUSIP.


The commercial real estate and housing markets have faced challenges and uncertainty amid the COVID-19 pandemic. Thus, NAIC's YE2020 CMBS and RMBS scenarios reflect such unsettled market and economic conditions while the collateral performance of CMBS and RMBS has been affected by the challenging environment. 

To assist insurers in their efforts to gauge the impact of these changes the NAIC completed an interim update on insurer's year-end 2019 holdings, free of charge. 

Please login to your 2019 STS Portfolio in AVS+ and click on the green button for "Generate RMBS and CMBS Interim Update" to download your interim RMBS and CMBS results. This link will remain available to you in your Structured Securities portfolio in AVS+ until November 30, 2020.

*Please note that these interim results are for informational purposes only and cannot be used for investment reporting. 

The official upcoming year end 2020 results are scheduled to be released in mid-December. Timeline and updates are provided on SSG's website. 

If you have any questions, please visit our SSG's website or contact us at 816-783-8707 or
