The trust fund (the "Trust") was created pursuant to a Pooling and Servicing Agreement dated as of September 1, 1997 (the "Pooling and Servicing Agreement") among BA Mortgage Securities, Inc. as the Depositor (the "Depositor"), Bank of America, Federal Savings Bank and Bank of America National Trust and Savings Association, as master servicers (together the "Master Servicers", and Bankers Trust Company of California, N.A., as trustee (the "Trustee") under the Pooling and Servicing Agreement, dated as of September 1, 1997, providing for the issuance of the Mortgage Pass-Through Certificates, Series 1997-2) The Series 1997-2 Mortgage Pass-Through Certificates (the "Certificates" will evidence the entire beneficial ownership interest in a trust fund (the "Trust Fund") consisting primarily of a pool of conventional, fixed-rate, one- to four-family first mortgage loans (the "Mortgage Loans" to be deposited by BA Mortgage Securities, Inc. (the "Depositor") into the Trust Fund for the benefit of the Certificateholders. Only Class IA-2, Class IA-3, Class IA-4, Class IA-5, Class IA-6, Class IA-7, Class IA-8, Class IIA-1, Class IIA-2, Class IIA-3, Class IIA-4, Class IIA-5, Class I-X, Class II-X, Class M, Class B-1, Class B-2, Class R-I, and Class R-II (the "Offered Certificates") are offered hereby. Information with respect to the business of the Trust would not be meaningful because the only "business" of the Trust is the collection on the Mortgage Loans and distribution of payments on the Certificates to Certificateholders. This information is accurately summarized in the Monthly Reports to Certificateholders, which are filed on Form 8-K. There is no additional relevant information to report in response to Item 101 of Regulation S-K. ITEM 2. Properties. The Depositor owns no property. The Mortgage Pass-Through Certificates, Series 1997-2, in the aggregate, represent the beneficial ownership in a Trust consisting primarily of the Mortgage Loans. The Trust will acquire title to real estate only upon default of the mortgagors under the Mortgage Loan. Therefore, this item is inapplicable. ITEM 3. Legal Proceedings. None. ITEM 4. Submission of Matters to a Vote of Security Holders. No matters were submitted to a vote of Certificateholders during the fiscal year covered by this report. PART II ITEM 5. Market for Registrant's Common Equity and Related Stockholder Matters. The Mortgage Pass-Through Certificates, Series 1997-2, represent, in the aggregate, the beneficial ownership in a trust fund consisting primarily of the Mortgage Loans. The Certificates are owned by Certificateholders as trust beneficiaries. Strictly speaking, the Registrant has no "common equity," but for purposes of this Item only, the Registrant's Mortgage Pass-Through Certificates, Series 1997-2 are treated as "common equity." (a) Market Information. There is no established public trading market for the Registrant's Certificates. The Registrant believes the Certificates are traded primarily in intra-dealer markets and non-centralized inter-dealer markets. (b) Holders. The number of registered holders of all classes of Certificates on December 31, 1997 was: [Participant listings for Cede & Co Fast, as a representative nominee for Class IA-2, Class IA-3, Class IA-4, Class IA-5, Class IA-6, Class IA-7, Class IA-8, Class IIA-1, Class IIA-2, Class IIA-3, Class IIA-4, Class IIA-5, Class I-X, Class II-X, Class M, Class B-1, and Class B-2 were unavailable from The Depository Trust Company. Total number of registered holders of all classes of Certificates will be reported on Form 10-K/A once participant listings become available]. (c) Dividends. Not applicable. The information regarding dividends required by sub-paragraph (c) of Item 201 of Regulation S-K is inapplicable because the Trust does not pay dividends. However, information as to distribution to Certificateholders is provided in the Monthly Reports to Certificateholders for each month of the fiscal year in which a distribution to Certificateholders was made. ITEM 6. Selected Financial Data. Not Applicable. Because of the limited activities of the Trust, the Selected Financial Data required by Item 301 of Regulation S-K does not add relevant information to that provided by the Monthly Reports to Certificateholders, which are filed on a monthly basis on Form 8-K. ITEM 7. Management's Discussion and Analysis of Financial Condition and Results of Operations. Not Applicable. The information required by Item 303 of Regulation S-K is inapplicable because the Trust does not have management per se, but rather the Trust has a Trustee who causes the preparation of the Monthly Reports to Certificateholders. The information provided by the Monthly Reports to Certificateholders, which are filed on a monthly basis on Form 8-K, does provide the relevant financial information regarding the financial status of the Trust.
