The adjustment described above resulted in the following changes to the June distribution: an overpayment of principal to the Class A-SB Certificateholders in an amount equal to $42,065.88, an overpayment of interest to the Class E Certificateholders in an amount equal to $5,701.17, an overpayment of interest to the Class F Certificateholders in an amount equal to $207,042.99, an overpayment of interest to the Class G Certificateholders in an amount equal to $1,134,128.09, an overpayment of principal to the holders of the RR Interest in an amount equal to $2,213.99 and an overpayment of interest to the holders of the RR Interest in an amount equal to $70,888.02.
