          (a)  The reason described in reasonable detail in Part III of this
               form could not be eliminated without unreasonable effort or
               expense

SEC 1344 (03-05)

               Persons who are to respond to the collection of information
               contained in this form are not required to respond unless the
               form displays a currently valid OMB control number.


PART III -- NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q,10-D, N-SAR,
N-CSR, or the transition report or portion thereof, could not be filed within
the prescribed time period.

     We seek relief pursuant to Rule 12b-25 to file a late Form 10-Q. The Form
10-Q for the period ended September 30, 2005 could not be filed without
unreasonable effort or expense and the subject quarterly report will be filed on
or before the fifth calendar day following the prescribed due date of November
9, 2005.

     On November 8, 2005, MBIA Inc. ("MBIA") announced that it is restating its
financial statements for 1998 and thereafter in connection with potential
settlements of investigations by the Securities Exchange Commission, the New
York Attorney General's Office and the New York State Insurance Department (the
"Regulatory Agencies") regarding agreements entered into by its subsidiary, MBIA
Insurance Corporation, in 1998 with AXA Re Finance S.A. ("AXA Re"), Muenchener
Rueckversicherings-Gesellschaft (Munich Re) and Converium Re (previously known
as Zurich Reinsurance North America). The restatement will correct and restate
MBIA's GAAP accounting for the agreements it entered into with Munich Re and AXA
Re. As a result, MBIA will account for these agreements as deposits because they
did not satisfy the risk transfer requirements for reinsurance accounting under
SFAS 113, "Accounting and Reporting for Reinsurance of Short-Duration and
Long-Duration Contracts". To date, no settlements have been approved by the
Regulatory Agencies. Any settlements may have additional or different terms.

     In addition, MBIA is restating results from 2001 to 2005 for derivative
transactions that do not technically comply with SFAS 133, "Accounting for
Derivative Instruments and Hedging Activities", even though these transactions
were highly effective from an economic standpoint. The effect of the restatement
is an increase to net income of $14.7 million for the first nine months and
$19.7 million for the third quarter. The cumulative effect of these changes,
from 2001 through September 2005, is a non-cash earnings increase of $6.8
million. Although the cumulative effect of $6.8 million is not material, since
MBIA is restating its financial results for the Munich Re and AXA Re reinsurance
agreements, it will restate each quarter and year affected by the prior method
of accounting.

     We are delaying the filing of our Form 10-Q in order to reflect these
restatements where necessary in the Form 10-Q.

PART IV -- OTHER INFORMATION

(1)  Name and telephone number of person to contact in regard to this
     notification 
     Ram D. Wertheim, Vice President, General Counsel
     and Secretary                                  (914)          765-3945
-------------------------------------------------------------------------------
     (Name)                                      (Area Code) (Telephone Number)

(2)  Have all other periodic reports required under Section 13 or 15(d) of the
     Securities Exchange Act of 1934 or Section 30 of the Investment Company Act
     of 1940 during the preceding 12 months or for such shorter period that the
     registrant was required to file such report(s) been filed ? If answer is
     no, identify report(s).                                     Yes |X| No |_|
     __________________________________________________________________________

(3)  Is it anticipated that any significant change in results of operations from
     the corresponding period for the last fiscal year will be reflected by the
     earnings statements to be included in the subject report or portion 
     thereof?                                                    Yes |X| No |_|

     If so, attach an explanation of the anticipated change, both narratively
     and quantitatively, and, if appropriate, state the reasons why a reasonable
     estimate of the results cannot be made.


     As discussed above in Part III of this form, MBIA will correct and restate
its 1998 and subsequent years' financial statements. Results for the quarter and
the year to date include the effects of a $75 million accrual for the total
amount MBIA estimates, based on discussions to date, it will have to pay in
connection with any settlements. MBIA anticipates that the subject report will
state that, after giving effect to this restatement and the $75 million accrual,
third quarter diluted net income per share declined 18 percent to $1.04 from
$1.27 in last year's third quarter, and that MBIA's net income for the third
quarter was $141.8 million, compared to $183.2 million in last year's third
quarter, a 23 percent decrease. MBIA anticipates that the subject report will
state other changes from the corresponding period for the last fiscal year once
completed.
