ITEM 8.01. Other Events
           ------------

On August 30, 2005, Banc of America Mortgage Securities, Inc., a Delaware
corporation (the "Registrant"), sold Mortgage Pass-Through Certificates, Series
2005-8, Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-6, Class
A-7, Class A-8, Class A-9, Class A-10, Class A-11, Class A-12, Class A-13, Class
A-14, Class A-R, Class 30-IO, Class 30-PO, Class B-1, Class B-2 and Class B-3
(the "Offered Certificates"), having an aggregate original principal balance of
$227,316,498.00. The Offered Certificates were issued pursuant to a Pooling and
Servicing Agreement, dated August 30, 2005, among the Registrant, Bank of
America, N.A., as servicer ("BANA"), and Wells Fargo Bank, N.A., as trustee (the
"Agreement"), a copy of which is filed as an exhibit hereto. Mortgage
Pass-Through Certificates, Series 2005-8, Class B-4, Class B-5 and Class B-6
Certificates, having an aggregate initial principal balance of $1,027,857.00
(the "Private Certificates" and, together with the Offered Certificates, the
"Certificates"), were also issued pursuant to the Agreement.

As of the date of initial issuance, the Offered Certificates evidenced an
approximate 99.55% undivided interest in a trust (the "Trust"), consisting
principally of a pool of fixed interest rate, conventional, monthly pay,
fully-amortizing, one- to four-family residential first mortgage loans. The
remaining undivided interests in the Trust are evidenced by the Private
Certificates distributions on which are subordinated to distributions on the
Offered Certificates.

Interest on the Offered Certificates will be distributed on each Distribution
Date (as defined in the Agreement). Monthly distributions in reduction of the
principal balance of the Offered Certificates will be allocated to the Offered
Certificates in accordance with the priorities set forth in the Agreement.
Distributions of interest and in reduction of principal balance on any
Distribution Date will be made to the extent that the Pool Distribution Amount
is sufficient therefor.

Elections will be made to treat designated portions of the Trust as two separate
REMICs for federal income tax purposes (the "Upper-Tier REMIC" and the
"Lower-Tier REMIC" and each a "REMIC"). The Class A-1, Class A-2, Class A-3,
Class A-4, Class A-5, Class A-6, Class A-7, Class A-8, Class A-9, Class A-10,
Class A-11, Class A-12, Class A-13, Class A-14, Class A-R, Class 30-IO, Class
30-PO, Class B-1, Class B-2, Class B-3, Class B-4, Class B-5 and Class B-6
Certificates will be treated as "regular interests" in the Upper-Tier REMIC and
the Class A-R Certificate will be treated as the "residual interest" in the
Lower-Tier REMIC.
