related Securities (and the related Terms Sheet will identify the category of any related Components) by means of one or more of these abbreviations. Distributions Distribution Dates Each month, the Trustee for a Series shall calculate the amount of principal and interest distributable on the Securities on the Distribution Date.  The Distribution Amount for each Series (or, if the Series is segregated into Security Groups, for each Security Group) for any Distribution Date for the related Series (or Security Group) will equal the sum of the Principal Distribution Amount (less principal, if any, payable to the Trustee as described in the Offering Circular Supplement), the Accrual Amount, if any, and the Interest Distribution Amount for the related Series (or Security Group). In the case of Trust MBS, the Trustee will determine the amount of principal expected to be received on each Trust MBS during that month on the basis of Certificate Factors for those Trust MBS for that month and efforts to verify with the related Ginnie Mae Issuers the accuracy with which they have reported such Certificate Factors.  The Trustee will obtain the Certificate Factors from the Information Agent on the seventh Business Day of the month (the “Certificate Factor Date”).  If the verification process reveals that a Ginnie Mae Issuer has incorrectly reported anticipated principal payments on which the Certificate Factor is based, the Trustee will determine (with the help of the Ginnie Mae Issuer), and publish, a Corrected Certificate Factor.   On occasion, the Trustee may be unable to verify by noon on the second Business Day preceding the Distribution Date that a Ginnie Mae Issuer has correctly reported the anticipated principal payments on which the Certificate Factor is based. In this case, the Trustee will calculate a Calculated Certificate Factor based on the assumption that all scheduled principal and interest payments were made but that  no prepayments were made during the immediately preceding month on the Mortgage Loans underlying the related Ginnie Mae Multifamily Certificate. In the case of Underlying Certificates, the Trustee will determine the amount of principal expected to be received on each Underlying Certificate during that month on the basis of Underlying Certificate Factors for those Underlying Certificates for that month.  The Trustee will obtain the Underlying Certificate Factors in accordance with the related Trust Agreement.  In the event that an Underlying Certificate Factor is not available on the date specified in the related Trust Agreement, no amounts in respect of principal for the related Underlying Certificate will be distributable to the related Securities on the following Distribution Date. The Class Factors for each Distribution Date will reflect the applicable Certificate Factors, Corrected Certificate Factors and and/or Calculated Certificate Factors for that month (or in the case of Underlying Certificates, the amount of principal distributable thereon on the preceding Underlying Certificate Payment Date).  Amounts calculated by the Trustee based on the Class Factors will be distributed to Holders of Securities on the applicable Distribution Date, whether or not those amounts are actually received on the Trust MBS.   Each Class Factor is the factor (carried to eight decimal places) that, when multiplied by the Original Class Principal Balance (or the original Class Notional Balance) of the related Class, Base Offering Circular – Multifamily 482090 6
