		<fieldName>Negative Amortization Indicator</fieldName>
		<comment>For anticipated repayment date mortgage loan: the anticipated repayment date mortgage loan (Asset Number 25) provides that, after the related anticipated repayment date, if the related borrower has not prepaid such mortgage loan in full, then any principal outstanding on that date will accrue interest at an increased interest rate rather than the original interest rate.  Following the related anticipated repayment date, (i) interest at the initial interest rate will continue to accrue and be payable on a current basis, and (ii) interest accrued at the revised rate in excess of interest accrued at the initial interest rate is to be deferred (and will itself accrue interest) and will be required to be paid only after the outstanding principal balance of the related mortgage loan has been paid in full.</comment>
