Saving
the TBA
by Andrew Davidson
The TBA (To
be announced) market is one of the world's greatest and successful
market innovations.
The TBA market
allows mortgage originators to sell mortgage loans before they are
closed and hedge the risk that mortgages won't close. Investors
can buy mortgages without the need to find the right number and
combination of small pools to add up to their investment target
and can finance their positions through dollar rolls. Read

Model Performance Review
by
Dan Szakallas
As expected,
prepayments decreased from April to May as rates rose approximately
50 basis points from the mid-April to the end of May. Speeds dropped
the sharpest in the 5.0 and 5.5 coupons, as these two groups became
discounts. For the range of 5.0's to 7.5's, FNMA 30's dropped by
35% from the previous month, while the corresponding GNMA 30's fell
by 22%. Actual pool CPR speeds of selected coupon buckets, along
with corresponding model forecasts, can be seen... Read

AD&Co. Update
AD&CO
RECAP -- JUNE 2004
12th
Annual Client Conference Recap
The 12th Annual
AD&Co Client Conference held in New York City on June 17th was
a resounding success. Attended by over 200 clients and friends,
this year's conference provided a platform for the introduction
of our new analytical paradigm called ValueNet, a forum for sharing
the knowledge our consultants have garnered during the past year,
and a rousing night of bowling.
We were pleased
to present seminars that focused on the analytical underpinnings
of the ValueNet system including backward induction, the active-passive
form of the prepayment model, enhanced pool level prepayment models,
and the theory and application behind prOAS based risk parameters.
These four models have been synthesized into a cohesive framework
to form ValueNet, which provides an analytical framework that uniformly
assesses the risk of MBS more quickly than brute force Monte Carlo.
To access the
presentations about ValueNet, please go to our website at www.ad-co.com

The afternoon
session featured two presentations by AD&Co consultants. The
first, presented by Anne Ching, focused on the techniques AD&Co
employs to value credit sensitive assets. Anne's presentation is
also available and is entitled "Valuation of Complex MBS".
Mickey Storms followed with an-depth look at the issues surrounding
the fair value accounting for MBS and derivatives. Mickey's presentation
is entitled: "Accounting vs Economics: A View of Fair Value
Accounting." For more information on our consulting services,
please do not hesitate to contact Laura Silberg.
At the conclusion
of the day session, 75 hearty souls ventured to Chelsea Piers for
the evening's festivities. The night's top bowlers included Troy
Grande, Doug Bendt and AD&Co's Steve Heller who rolled the evening's
high game of 169. It turned out to be a great evening of networking,
eating, drinking and bowling under the neon lights. AD&Co thanks
everyone who contributed to the success of AD&Co's 2004 conference.
We look forward to seeing you all again in 2005.
