Report of Independent Registered Public Accounting Firm


To the Board of Directors and Shareholder
of Bank of America, N.A.:


We have examined management's assertion concerning the mortgage division of Bank
of America, N.A.'s (the "Company"), compliance with the minimum servicing
standards identified in the Mortgage Bankers Association of America's Uniform
Single Attestation Program for Mortgage Bankers ("USAP") as of and for the year
ended December 31, 2005 included in the accompanying Management's Assertion
Concerning Compliance with USAP Minimum Servicing Standards (see Exhibit 1).
Management is responsible for the Company's compliance with those minimum
servicing standards. Our responsibility is to express an opinion on management's
assertion about the Company's compliance based on our examination.

Our examination was made in accordance with standards established by the
American Institute of Certified Public Accountants and, accordingly included
examining on a test basis evidence about the Company's compliance with the
minimum servicing standards and performing such other procedures as we
considered necessary in the circumstances. We believe that our examination
provides a reasonable basis for our opinion. Our examination does not provide a
legal determination on the Company's compliance with the minimum servicing
standards.

In our opinion, management's assertion that the Company complied with the
aforementioned minimum servicing standards as of and for the year ended December
31, 2005 is fairly stated, in all material respects.
