ITEM 5.     Other Events

            On April 24, 2003, Banc of America Mortgage Securities, Inc., a
Delaware corporation (the "Registrant"), sold Mortgage Pass-Through
Certificates, Series 2003-D, Class 1-A-1, Class 1-A-2, Class 1-A-R, Class
1-A-LR, Class 2-A-1, Class 2-A-2, Class 2-A-3, Class 2-A-4, Class 2-A-5, Class
2-A-6, Class 3-A-1, Class A-P, Class B-1, Class B-2 and Class B-3 (the "Offered
Certificates"), having an aggregate original principal balance of
$861,289,008.00. The Offered Certificates were issued pursuant to a Pooling and
Servicing Agreement, dated April 24, 2003, among the Registrant, Bank of
America, N.A., as servicer ("BANA") and Wells Fargo Bank Minnesota, National
Association, as trustee (the "Agreement"), a copy of which is filed as an
exhibit hereto. Mortgage Pass-Through Certificates, Series 2003-D, Class SES,
Class WIO, Class B-4, Class B-5 and Class B-6 Certificates, having an aggregate
initial principal balance of $4,328,983.00 (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 99.50% undivided interest in a trust (the "Trust"),
consisting principally of three pools of adjustable interest rate, 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.

            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 (as defined in the Agreement) is sufficient therefor.

            Elections will be made to treat 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 1-A-1, Class 2-A-1, Class 1-A-R, Class 1-A-LR,
Class 2-A-1, Class 2-A-2, Class 2-A-3, Class 2-A-4, Class 2-A-5, Class 2-A-6,
Class 3-A-1, Class B-1, Class B-3, Class B-4, Class B-5 and Class B-6
Certificates and each component of the Class A-P, Class SES and Class WIO
Certificates will be treated as "regular interests" in the REMIC and the Class
1-A-R and Class 1-A-LR Certificates will be treated as the "residual interest"
in the Upper-Tier REMIC and the Lower-Tier REMIC, respectively.
