Realized Losses On each Distribution Date, immediately following the distributions to be made on such date pursuant to Section 4.01(b), the Certificate Administrator shall calculate the amount, if any, of the Pooled Realized Loss and VRR Realized Loss for such Distribution Date. Any allocation of Realized Losses to any Class of Pooled Principal Balance Certificates and VRR Realized Losses to the VRR Interest shall be made by reducing the Certificate Balance or VRR Interest Balance, as applicable, thereof by the amount so allocated. On each Distribution Date, immediately following the distributions to be made on such date pursuant to Section 4.01(c), the Certificate Administrator shall calculate the amount, if any, of the 180 Water Non-VRR Realized Loss and 180 Water VRR Realized Loss for such Distribution Date. Any allocation of 180 Water Non-VRR Realized Losses to any Class of Loan-Specific Certificates and 180 Water VRR Realized Losses to the 180W-VRR Interest shall be made by reducing the Certificate Balance thereof by the amount so allocated. The allocation of Pooled Realized Losses and VRR Realized Losses, and 180 Water Non-VRR Realized Losses and 180 Water VRR Realized Losses, shall constitute allocations of losses and other shortfalls experienced by the Trust Fund. The Certificate Balances of each Class of Pooled Principal Balance Certificates will be reduced without distribution on any Distribution Date as a write-off to the extent of any Pooled Realized Losses allocated to such Class of Certificates with respect to such date. Any such write-offs will be applied to the Classes of Pooled Principal Balance Certificates in the following order, in each case until the Certificate Balance of such Class is reduced to zero: first, to the Class H-RR Certificates; second, to the Class G-RR Certificates; third, to the Class F Certificates; fourth, to the Class E Certificates; fifth, to the Class D Certificates; sixth, to the Class C Certificates; seventh, to the Class B Certificates, eighth, to the Class A-M Certificates; and finally, to the Class A-1, Class A-2, Class A-3, Class A-SB, Class A-4 and Class A-5 Certificates, pro rata, based on their respective Certificate Balances. The Certificate Balances of each Class of 180 Water Non-VRR Certificates will be reduced without distribution on any Distribution Date as a write-off to the extent of any 180 Water Non-VRR Realized Losses allocated to such Class of 180 Water Non-VRR Certificates with respect to such date. Any such write-offs will be applied to the Classes of 180 Water Non-VRR Certificates in the following order, in each case until the Certificate Balance of such Class is reduced to zero: first, to the Class 180W-D Certificates, second, to the Class 180W-C Certificates, third, to the Class 180W-B Certificates, and finally, to the Class 180W-A Certificates, in each case until the remaining Certificate Balances of such Classes of Certificates have been reduced to zero. Any Realized Losses so allocated to any Class of Certificates shall be allocated among the respective Certificates of such Class in proportion to the Percentage Interests evidenced thereby. On each Distribution Date, any VRR Realized Loss for such Distribution Date shall be allocated to the VRR Interest; and, in connection therewith, the VRR Interest Balance will be reduced without distribution, as a write-off, to the extent of such VRR Realized Loss. Distributions in reimbursement of Pooled Realized Losses or VRR Realized Losses, as applicable, previously allocated to the respective Classes of the Pooled Principal Balance Certificates and distributions in reimbursement of VRR Realized Losses previously allocated to the Class VRR Upper Tier Regular Interest shall be made in the amounts and manner specified in Section 4.01(b) or Section 4.01(d), as applicable. Additional Trust Fund Expenses and shortfalls in Pooled Aggregate Available Funds due to extraordinary expenses of the Trust Fund (including indemnification expenses), a reduction in the Mortgage Rate on a Mortgage Loan by a bankruptcy court pursuant to a plan of reorganization or pursuant to any of its equitable powers, or otherwise, shall be treated as and allocated in the same manner as Realized Losses and VRR Realized Losses. Reimbursement of previously allocated Pooled Realized Losses and VRR Realized Losses will not constitute distributions of principal for any purpose and will not result in an additional reduction in the Certificate Balance of the Class of Certificates or Class of Class VRR Upper-Tier Regular Interest in respect of which any such reimbursement is made. Distributions in reimbursement of 180 Water Non-VRR Realized Losses or 180 Water VRR Realized Losses, as applicable, previously allocated to the respective Classes of the Loan-Specific Certificates and distributions in reimbursement of 180 Water VRR Realized Losses previously allocated to the 180W-VRR Interest shall be made in the amounts and manner specified in Section 4.01(c) or Section 4.01(c), as applicable. Additional Trust Fund Expenses attributable to the 180 Water Subordinate Companion Loan and shortfalls in 180 Water Available Funds due to extraordinary expenses of the Trust Fund (including indemnification expenses), a reduction in the Mortgage Rate on a Mortgage Loan by a bankruptcy court pursuant to a plan of reorganization or pursuant to any of its equitable powers, or otherwise, shall be treated as and allocated in the same manner as 180 Water Non-VRR Realized Losses and 180 Water VRR Realized Losses. Reimbursement of previously allocated 180 Water Non-VRR Realized Losses and 180 Water VRR Realized Losses will not constitute distributions of principal for any purpose and will not result in an additional reduction in the Certificate Balance of the Class of 180 Water Non-VRR Certificates or 180W-VRR Interest in respect of which any such reimbursement is made. If and to the extent any Nonrecoverable Advances (plus interest thereon) that were reimbursed from principal collections on the Mortgage Loans and previously resulted in a reduction of the Aggregate Principal Distribution Amount are subsequently recovered on the related Mortgage Loan, then (on the Distribution Date related to the Collection Period during which the recovery occurred): (i) the Non-VRR Percentage of the amount of such recovery will be added to the Certificate Balance of the Classes of Principal Balance Certificates that previously were allocated Realized Losses, in the same sequential order as distributions pursuant to Section 4.01(b), in each case up to the lesser of (A) the unallocated portion of the Non-VRR Percentage of the amount of such recovery and (B) the amount of the unreimbursed Realized Losses previously allocated to the subject Class of Certificates, and the Interest Shortfall with respect to each affected Class of Non-VRR Certificates for the next Distribution Date will be increased by the aggregate amount of interest that would have accrued through the then current Distribution Date if the restored write-down for the reimbursed Class of Pooled Principal Balance Certificates had never been written down; and (ii) the VRR Percentage of the amount of such recovery will be added to the Certificate Balance of the Class VRR Upper-Tier Regular Interest up to the lesser of (A) the VRR Percentage of the amount of such recovery and (B) the amount of the unreimbursed VRR Realized Losses previously allocated to the Class VRR Upper-Tier Regular Interest, and the interest payable on the Class VRR Upper-Tier Regular Interest will be deemed increased by the VRR Allocation Percentage of any contemporaneous increases in interest payable on the Non-VRR Certificates pursuant to clause (i) of this sentence. To the extent that the Certificate Balance of, and/or any interest payable on, any Class of Non-VRR Certificates or the VRR Interest is so increased, an identical increase shall be deemed made to the Lower-Tier Principal Balance of, and any interest payable on, the Corresponding Lower-Tier Regular Interest. If the Certificate Balance of any Class of Principal Balance Certificates or Class VRR Upper-Tier Regular Interest (or the Lower-Tier Principal Balance of any Lower-Tier Regular Interest) is so increased, the amount of unreimbursed Realized Losses or VRR Realized Losses, as applicable, of such Class of Principal Balance Certificates or VRR Interest (or such Lower-Tier Regular Interest), as the case may be, shall be decreased by such amount, and any interest accrued on the amount of unreimbursed Realized Losses or VRR Realized Losses, as applicable, so decreased shall be deemed not to exist. With respect to any Distribution Date, any Pooled Realized Losses or VRR Realized Losses, as applicable, allocated pursuant to this Agreement with respect to such Distribution Date shall reduce the Lower-Tier Principal Balances of the Lower-Tier Regular Interests as a write-off and shall be allocated among the Lower-Tier Regular Interests in the same priority as the Class of Corresponding Certificates. With respect to any Distribution Date, any 180 Water Non-VRR Realized Losses or 180 Water VRR Realized Losses, as applicable, allocated pursuant to this Agreement with respect to such Distribution Date shall reduce the principal balances of the Trust Subordinate Companion Loan REMIC Regular Interests as a write-off and shall be allocated among the Trust Subordinate Companion Loan REMIC Regular Interests in the same priority as the Class of Corresponding Certificates.
