The Housing Financing Fund (HFF), pursuant to the Housing Act No. 44/1998, as subsequently amended, is authorised to make additional calls of Housing Bonds. This authorisation corresponds to the authorisation of real estate mortgagors to make additional payments on their mortgages or to repay the debt in full prior to maturity. Provisions to this effect have existed in housing affairs legislation since the adoption of Act No. 75/1989 which established the Housing Bond system. By virtue of the above, HFF has selected the Housing Bonds to be called. The selection was made in such a manner that calls in each Housing Bond series directly reflect the paybacks of Housing Bond mortgages in this same series. This maintains a complete correspondence between paybacks and calls, as provided for by law. Additional calls are made on an ongoing basis to equalise HFF's cash flow as a result of paybacks, in accordance with the abovementioned statutory provisions. Housing Bonds from the following bond certificate series were selected for these additional calls to be paid on November 15th 2010: Bond Series Nominal Value Series 1,1989 ( IBH14-0115 ) 25.520.000 Series 1,1990 ( IBH15-0815 ) 33.135.000 Series 2,1990 ( IBH15-1115 ) 43.360.000 Series 2,1991 ( IBH16-0515 ) 58.880.000 Series 3,1992 ( IBH17-0815 ) 76.720.000 Series 2,1993 ( IBH18-0815 ) 43.420.000 Series 2,1994 ( IBH19-0515 ) 125.860.000 Series 3,1994 ( IBH19-0815 ) 72.460.000
