Item 5.        Other Events.

     The following are Collateral Term Sheets prepared by Citicorp Mortgage
Securities, Inc. ("CMSI") in connection with the offering of its REMIC Pass-
Through Certificates, Series 2003-7. The information set forth in these
Collateral Term Sheets will be superseded in its entirety by the information set
forth in the final prospectus for the Series 2003-7 REMIC Pass-Through
Certificates and by any subsequent Collateral Term Sheets filed under Form 8-K
subsequent to the date hereof related to the Series 2003-7 REMIC Pass-Through
Certificates.

     On August 27, 2003, CMSI is to transfer to the Trustee mortgage loans(1)
with an aggregate scheduled principal balance outstanding (after deducting
principal payments due on or before August 1, 2003) as of August 1, 2003 of
$279,493,514.97. Information below is provided with respect to all mortgage
loans expected to be included in the mortgage loan pool.

     The total number of mortgage loans as of August 1, 2003 was 571. The
weighted average interest rate on the mortgage loans (before deduction of the
servicing fee) as of August 1, 2003 was 5.515%. The weighted average remaining
term to stated maturity of the mortgage loans as of August 1, 2003 was 177.34
months. All mortgage loans have original maturities of at least 10 but no more
than 15 years. None of the mortgage loans were originated prior to April 1, 2002
or after August 1, 2003. The weighted average original term to stated maturity
of the mortgage loans as of August 1, 2003 was 179.55 months.

     None of the mortgage loans has a scheduled maturity later than August 1,
2018. Each mortgage loan had an original principal balance of not less than
$44,000 nor more than $1,000,000. Mortgage loans having an aggregate scheduled
principal balance of $722,043 as of August 1, 2003 had loan-to-value ratios at
origination in excess of 80%, but no mortgage loans had loan-to-value ratios in
excess of 95%. The weighted average loan-to-value ratio at origination of the
mortgage loans as of August 1, 2003 was 53.3%. No more than $4,130,261 of the
mortgage loans are secured by mortgaged properties located in any one zip code.
At least 94%(2) of the mortgage loans are secured by mortgaged properties
determined by CitiMortgage, Inc. to be the primary residence of the borrower.


-----------

1     Terms used herein and not defined have the meaning assigned thereto in the
      form of Prospectus included in CMSI's Registration Statement (333-72082).

2     Such percentages are expressed as a percentage of the aggregate scheduled
      principal balance of the mortgage loans having such characteristics
      relative to the aggregate scheduled principal balance of all mortgage
      loans.

<PAGE>


     At least 93% of the mortgage loans will be mortgage loans originated using
loan underwriting policies which require, among other things, proof of income
and liquid assets and telephone verification of employment, or are refinanced
mortgage loans originated using alternative or streamlined underwriting
policies. No more than 7% of the mortgage loans will be mortgage loans
originated using a loan underwriting policy which, among other things, requires
verification of employment and may require proof of liquid assets, but does not
require verification of income as stated on the loan application. No more than
86% of the mortgage loans will be refinanced mortgage loans originated using
alternative or streamlined underwriting policies.

     All of the mortgage loans which had loan-to-value ratios greater than 80%
at origination had primary mortgage insurance as of such date. In the case of
the mortgage loans for which additional collateral was pledged, taken as a
group:

      1.    the number of such mortgage loans is 1;

      2.    such mortgage loan had an aggregate scheduled principal balance of
            $242,137;

      3.    the weighted average loan-to-value ratio of such mortgage loan,
            taking into account the loanable value of the pledged additional
            collateral, is 80.0%; and

      4.    the weighted average loan-to-value ratio of such mortgage loan,
            without taking into account the loanable value of the pledged
            additional collateral, is 91.0%.

     Premium loans will consist of mortgage loans with net loan rates greater
than or equal to 4.750%. Discount loans will consist of mortgage loans with net
loan rates less than 4.750%. The aggregate scheduled principal balances
outstanding as of the cut-off date of the premium loans and the discount loans
were $276,562,242 and $2,931,273, respectively. The weighted average interest
rates of the premium loans and the discount loans, as of the cut-off date, were
5.522% and 4.875%, respectively. The weighted average remaining terms to stated
maturity of the premium loans and the discount loans, as of the cut-off date,
were 177.32 months and 179.31 months, respectively.

Item 5.        Other Events.

     The following are Collateral Term Sheets prepared by Citicorp Mortgage
Securities, Inc. ("CMSI") in connection with the offering of its REMIC Pass-
Through Certificates, Series 2003-7. The information set forth in these
Collateral Term Sheets will be superseded in its entirety by the information set
forth in the final prospectus for the Series 2003-7 REMIC Pass-Through
Certificates and by any subsequent Collateral Term Sheets filed under Form 8-K
subsequent to the date hereof related to the Series 2003-7 REMIC Pass-Through
Certificates.

     On August 27, 2003, CMSI is to transfer to the Trustee mortgage loans(1)
with an aggregate scheduled principal balance outstanding (after deducting
principal payments due on or before August 1, 2003) as of August 1, 2003 of
$279,493,514.97. Information below is provided with respect to all mortgage
loans expected to be included in the mortgage loan pool.

     The total number of mortgage loans as of August 1, 2003 was 571. The
weighted average interest rate on the mortgage loans (before deduction of the
servicing fee) as of August 1, 2003 was 5.515%. The weighted average remaining
term to stated maturity of the mortgage loans as of August 1, 2003 was 177.34
months. All mortgage loans have original maturities of at least 10 but no more
than 15 years. None of the mortgage loans were originated prior to April 1, 2002
or after August 1, 2003. The weighted average original term to stated maturity
of the mortgage loans as of August 1, 2003 was 179.55 months.

     None of the mortgage loans has a scheduled maturity later than August 1,
2018. Each mortgage loan had an original principal balance of not less than
$44,000 nor more than $1,000,000. Mortgage loans having an aggregate scheduled
principal balance of $722,043 as of August 1, 2003 had loan-to-value ratios at
origination in excess of 80%, but no mortgage loans had loan-to-value ratios in
excess of 95%. The weighted average loan-to-value ratio at origination of the
mortgage loans as of August 1, 2003 was 53.3%. No more than $4,130,261 of the
mortgage loans are secured by mortgaged properties located in any one zip code.
At least 94%(2) of the mortgage loans are secured by mortgaged properties
determined by CitiMortgage, Inc. to be the primary residence of the borrower.

-----------

1     Terms used herein and not defined have the meaning assigned thereto in the
      form of Prospectus included in CMSI's Registration Statement (333-72082).

2     Such percentages are expressed as a percentage of the aggregate scheduled
      principal balance of the mortgage loans having such characteristics
      relative to the aggregate scheduled principal balance of all mortgage
      loans.
At least 93% of the mortgage loans will be mortgage loans originated using
loan underwriting policies which require, among other things, proof of income
and liquid assets and telephone verification of employment, or are refinanced
mortgage loans originated using alternative or streamlined underwriting
policies. No more than 7% of the mortgage loans will be mortgage loans
originated using a loan underwriting policy which, among other things, requires
verification of employment and may require proof of liquid assets, but does not
require verification of income as stated on the loan application. No more than
86% of the mortgage loans will be refinanced mortgage loans originated using
alternative or streamlined underwriting policies.

     All of the mortgage loans which had loan-to-value ratios greater than 80%
at origination had primary mortgage insurance as of such date. In the case of
the mortgage loans for which additional collateral was pledged, taken as a
group:

      1.    the number of such mortgage loans is 1;

      2.    such mortgage loan had an aggregate scheduled principal balance of
            $242,137;

      3.    the weighted average loan-to-value ratio of such mortgage loan,
            taking into account the loanable value of the pledged additional
            collateral, is 80.0%; and

      4.    the weighted average loan-to-value ratio of such mortgage loan,
            without taking into account the loanable value of the pledged
            additional collateral, is 91.0%.

     Premium loans will consist of mortgage loans with net loan rates greater
than or equal to 4.750%. Discount loans will consist of mortgage loans with net
loan rates less than 4.750%. The aggregate scheduled principal balances
outstanding as of the cut-off date of the premium loans and the discount loans
were $276,562,242 and $2,931,273, respectively. The weighted average interest
rates of the premium loans and the discount loans, as of the cut-off date, were
5.522% and 4.875%, respectively. The weighted average remaining terms to stated
maturity of the premium loans and the discount loans, as of the cut-off date,
were 177.32 months and 179.31 months, respectively.
The following tables set forth information regarding the mortgage loans as
of August 1, 2003.
