R&R Consulting described how the reports presented to RMBS investors show losses at the loan level that have NOT been allocated to the bonds. From R&R Consulting:
On the securities performing at December 2011, a universe of approximately $1.42 trillion, R&R estimate the amount of additional losses likely to materialize is $300 billion, with one-third concentrated in ten arranger names, including Countrywide, Morgan Stanley and JP Morgan. About 17,000 tranches, or 34% of the universe analyzed by R&R, may lose up to 83% of their remaining principal.
In addition, R&R estimates that approximately $175 billion of losses already incurred on the loans have not yet been allocated to the bonds in the related transactions. Failure to allocate realized loan losses could distort the valuation of related RMBS tranches.
In the course of conducting valuations on RMBS, the R&R analytics team discovered widespread, serious, repeated data discrepancies. Ann Rutledge, a founding principal, asked the team to measure the magnitude of the discrepancy on the RMBS universe. To do this, R&R subtracted cumulative losses allocated to the tranches from unallocated, expected losses, calculated as the sum of defaults, bankruptcies, foreclosures and REOs minus recoveries. “The results were very disturbing: $175 billion of unallocated current losses and $300 billion of imminent losses,” Rutledge said.
