AM Best Updates Net Capital Charge Associated with Fannie-Freddie Mortgage Risk Transfers – InsuranceNewsNet

AM Best released newly updated tables of net capital charges associated with a representative sample of Fannie Mae and Freddie Mac credit risk transfer (CRT) mortgage transactions Freddie Mac’s Agency Credit Insurance Structure (ACIS) and Fannie Mae’s Credit Insurance Risk Transfer (CIRT). These tables also highlight some of the key elements of the factor method used to calculate net capital charges in Best’s Capital Adequacy Ratio (BCAR) model.

The net capital charge of CRT transactions is represented by B5mNet Mortgage Loss and LAE Reserves Riskin the net required capital formula which is part of the BCAR. It is based on unexpected losses and premiums associated with transactions and is represented as a fraction of initial exposures. For that Best Special Report“Updated Net Capital Charge Tables for ACIS/CIRT Reinsurance Transactions”, the seventh on net capital charges, AM Best selected approximately half of the 141 CRT transactions effective through June 2022 to calculate the net capital charges associated with the individual layers of CRT transactions.

According to the report, a handful of transactions remain under trigger events due to failed delinquency tests, despite the sharp decline in the national delinquency rate in recent months, leading to no allocation of main to junior slices. This will not affect AM Best’s net capital charge calculation, as the calculation assumes stress scenarios with trigger events in place for each transaction.

The report also notes that the ultimate effect of the pandemic on ACIS/CIRT transactions remains unknown, as the forbearance of some borrowers is not yet over. Forbearance, loan modifications and foreclosure moratoriums have slowed the rate at which losses in the pools of these transactions are growing. At the very least, the forbearance delayed the realization of the losses simply because of the time it took to go through the foreclosure process after the maximum forbearance period expired.

AM Best publishes these net capital requirement charts semi-annually, using the most recent performance data available from government-sponsored company websites. Future releases of net capital charges will depend on the continued and timely availability of data from Fannie Mae and Freddie Mac, among other factors.
