•   Investors  can  calculate  the  amount  of  interest  to  be  distributed  on  each  Class  of Securities  for  any  Distribution  Date  by  using  the  Class  Factors  published  in  the preceding month. See "– Class Factors" below. Categories of Classes For  purposes  of  interest  distributions,  the  Classes  will  be  categorized  as  shown  under "Interest  Type"  on  the  inside  cover  page  of  this  Supplement  and  on  Schedule  I  to  this Supplement.  The  abbreviations  used  on  the  inside  cover  page  and  on  Schedule  I  to  this Supplement are explained under "Class Types" in Appendix I to the Base Offering Circular. Accrual Periods The Accrual Period for each Class is set forth in the table below: Class Accrual Period Fixed Rate and Delay Classes The calendar month preceding the related Distribution Date Floating Rate and Inverse Floating Rate Classes (other than Delay Classes) From the 20th day of the month preceding the month of the related Distribution Date through the 19th day of the month of that Distribution Date Fixed Rate Classes Each Fixed Rate Class will bear interest at the per annum Interest Rate shown on the inside cover page of this Supplement or on Schedule I to this Supplement. Floating Rate and Inverse Floating Rate Classes The Floating Rate and Inverse Floating Rate Classes will bear interest as shown under "Terms Sheet – Interest Rates" in this Supplement. The Interest Rates for the Floating Rate and Inverse Floating Rate Classes will be based on LIBOR. LIBOR will be determined based on the BBA LIBOR method, as described under "Description of the Securities – Interest Rate Indices – Determination of LIBOR – BBA LIBOR" in the Base Offering Circular. For  information  regarding  the  manner  in  which  the  Trustee  determines  LIBOR  and calculates  the  Interest  Rates  for  the  Floating  Rate  and  Inverse  Floating  Rate  Classes,  see "Description of the Securities – Interest Rate Indices – Determination of LIBOR" in the Base Offering Circular. The Trustee's determination of LIBOR and its calculation of the Interest Rates will be final, except in the case of clear error. Investors can obtain LIBOR levels and Interest Rates for the current and preceding Accrual Periods from Ginnie Mae's Multiclass Securities e-Access located on Ginnie Mae's website ("e-Access") or by calling the Information Agent at (800) 234-GNMA. Accrual Classes Each of Class ZA, ZB and ZC is an Accrual Class. Interest will accrue on the Accrual Classes and be distributed as described under "Terms Sheet – Accrual Classes" in this Supplement. Principal Distributions The Principal Distribution Amount or the Adjusted Principal Distribution Amount for each Group,  as  applicable,  and  the  ZA,  ZB  and  ZC  Accrual  Amounts  will  be  distributed  to  the Holders entitled thereto as described under "Terms Sheet – Allocation of Principal" in this S-14
