The Continued Evolution of Non Agency Loan
Classifications
Issuance Overview
In the last few years, we have
witnessed a structural shift in the market share of agency and
non agency issuance. In reviewing the MBS issuance of 2003, approximately
78% of MBS issuance was agency collateral as defined by FNMA,
FHLMC and GNMA collateral with the remaining 22% of issuance
being non-agency product. By the second quarter of 2005, agency
issuance had declined to approximately 44% of total MBS issuance.
Non Agency issuance as defined as private label jumbo, alt a
transactions, and mortgage related ABS, including subprime, HEL,
HELOCS, and high ltv loans comprised the remaining 56% of total
MBS issuance. We have seen the federal agencies such as FNMA
and FHLMC increase its market share of ‘down in credit’ loans
while at the same time, subprime originators have gone ‘up
in credit’; capturing some of the borrowers that initially
would have fallen under more of the agency originator guidelines.
Sector Classification
Creating a distinction between
the non agency prime and nonprime cohorts for the valuation of
the mortgage servicing rights is of importance as prepayment,
default and loan level performance varies to a large degree between
these two asset classes. Non agency Prime loans originated in
2004 and 2005 can be best classified with loan level attributes
that had average fico scores of approximately 730, fixed rates
that averaged around 5.80% and arms below 5.00%, average balances
of over $400,000 and average margins on the arm product below
3.00%. With the majority of market share in the non agency near
prime sector focused on arms, the general characteristics of
2004 & 2005 originated Alt A arm product had average ficos
of 710, ltv’s of 75, gross wacs in the mid 5’s and
average balances of approximately $270,000. On the other hand,
the more Alt B looking product had average ficos of 653, gross
wacs in the low 7.00’s, higher ltv’s, average balances
around $150,000 to $165,000 and average margins around 5.60%.
The Subprime Arm asset class, having the largest market share
in the non prime sector, had average gross wac’s again
in the low 7.00’s, but with average ficos around the 610-620,
ltv’s slightly over 80% and gross margins of approximately
6.00%. Portfolio performance varies widely between these various
asset classes.
Impact on MSRs
With respect to the impact on
MSRs, further granularity in msr asset classes distinction would
result in quite dramatic valuation assumption changes to such
major drivers of value as discount rates and cost to service,
in both performing and non performing classes. Each asset class
has very distinct delinquency and foreclosure curves in addition
to asset specific prepayment vectors. Utilizing valuation assumption
sets that are consistent in prime loan analysis for non prime
valuation analysis will result in dramatic valuation differentials
that can lead to mismatched risk exposure, mark to market variances,
and potential write downs of the mortgage servicing asset.
MIAC has developed the most sophisticated
analytical tools to tackle the increase complexity of these new
asset classes. With the Fair Market Valuation looming in the
near future holders of MSR assets should be thoroughly reviewing
whether they have the right valuation assumptions and valuation
methodologies in place for these new asset classes. MIAC expects
to update the characteristics of the GSA portfolio once again
in November 2005.

the marketplace have increased or declined to a greater or lesser
extent. These Indexes DO NOT represent multiples indicative of
