The Class Z Securities are Accrual Securities. Holders of Accrual Securities are required to accrue income from their Securities (other than income attributable to market discount or de minimis market discount) under the OID rules based on the expected payments on the Accrual Securities at the prepayment assumption described below. In addition to the Regular Securities described in the preceding two paragraphs, based on anticipated prices (including accrued interest), certain Mortgage Loan characteristics and the prepayment assumption described below, Class A is expected to be issued with OID. Prospective investors in the Regular Securities should be aware, however, that the forego- ing expectations about OID could change because of differences between anticipated purchase prices  and  actual  purchase  prices.  The  prepayment  assumption  that  should  be  used  in determining the rates of accrual of OID, if any, on the Regular Securities is 15% CPR and 100% PLD (as described in "Yield, Maturity and Prepayment Considerations" in this Supplement). No representation is made, however, about the rate at which prepayments on the Mortgage Loans underlying the Ginnie Mae Multifamily Certificates actually will occur.  See  "Certain Federal Income Tax Consequences" in the Multifamily Base Offering Circular. The  Regular  Securities  generally  will  be  treated  as  "regular  interests"  in  a  REMIC  for domestic building and loan associations and "real estate assets" for real estate investment trusts ("REITs") as described in "Certain Federal Income Tax Consequences" in the Multifamily Base Offering Circular. Similarly, interest on the Regular Securities will be considered "interest on obligations secured by mortgages on real property" for REITs. Residual Securities The Class RR Securities will represent the beneficial ownership of the Residual Interest in the Pooling REMIC and the beneficial ownership of the Residual Interest in the Issuing REMIC. The Residual Securities, i.e., the Class RR Securities, generally will be treated as "residual interests" in a REMIC for domestic building and loan associations and as "real estate assets" for REITs, as described in "Certain Federal Income Tax Consequences" in the Multifamily Base Offering Circular, but will not be treated as debt for federal income tax purposes. Instead, the Holders of the Residual Securities will be required to report, and will be taxed on, their pro rata shares of the taxable income or loss of the Trust REMICs, and these requirements will continue until there are no outstanding regular interests in the respective Trust REMICs. Thus, Residual Holders will have taxable income attributable to the Residual Securities even though they will not receive principal or interest distributions with respect to the Residual Securities, which could result in a negative after-tax return for the Residual Holders. Even though the Holders of the Class RR Securities are not entitled to any stated principal or interest payments on the Class RR Securities, the Trust REMICs may have substantial taxable income in certain periods, and offsetting tax losses may not occur until much later periods. Accordingly, a Holder of the Class RR Securities may experience substantial adverse tax timing consequences. Prospective investors  are  urged  to  consult  their  own  tax  advisors  and  consider  the  after-tax  effect  of ownership  of  the  Residual  Securities  and  the  suitability  of  the  Residual  Securities  to  their investment objectives. Prospective Holders of Residual Securities should be aware that, at issuance, based on the expected  prices  of  the  Regular  and  Residual  Securities  and  the  prepayment  assumption described above, the residual interests represented by the Residual Securities will be treated as "noneconomic residual interests" as that term is defined in Treasury regulations. Regulations were recently finalized regarding the federal income tax treatment of "induce- ment  fees"  received  by  transferees  of  noneconomic  REMIC  residual  interests.  The  final regulations (i) provide tax accounting rules for the treatment of such fees as income over an S-27
