> *Description*
> During flat-rate loan schedule generation and recalculation, an `ArithmeticException` (division by zero) occurs if a `PRINCIPAL_AMOUNT` term variation is applicable on the final installment period (where `periodNumber == actualNumberOfRepayments`).
> *Root Cause Analysis*
> In `LoanApplicationTerms.java`, the method `calculateTotalPrincipalPerPeriodWithoutGrace` computes schedule adjustments for flat loans:
> {code:java}
> if (!isPrincipalGraceApplicableForThisPeriod(periodNumber) && currentPeriodFixedPrincipalAmount != null) {
>     this.adjustPrincipalForFlatLoans = this.adjustPrincipalForFlatLoans.plus(principalPerPeriod
>             .minus(currentPeriodFixedPrincipalAmount).dividedBy(this.actualNumberOfRepayments - periodNumber, mc));
> }
> {code}
