The affirmations reflect satisfactory credit enhancement (CE)
relationships to future loss expectations and affect approximately
$2.47 billion in outstanding certificates as of the December 2007
distribution date. The classes downgraded total approximately $66.8
million and the classes placed on Rating Watch Negative total
approximately $1.9 million. These rating actions reflect the
deterioration of CE relative to future expected losses.

The underlying collateral in these transactions consists of
fixed-rate mortgage loans secured by first liens on one- to
four-family residential properties. Bank of America, N.A., currently
rated 'RPS1' by Fitch for ALT-A transactions, is the servicer for
these loans. These transactions are seasoned from a range of 9 months
(ALT 2007-1) to 45 months (ALT 2004-3). The pool factors (i.e.,
current mortgage loans outstanding as a percentage of the initial
pool) range from 52% to 88%. The 90+ delinquencies range from 0.07%
(ALT 2004-3 Group 4) to 2.64% (ALT 2007-1) of current collateral
balances. The cumulative losses range from 0% (ALT 2006-1 and ALT
2007-1) to 0.31% (ALT 2004-3 Groups 1 - 3) of original collateral
balances.
