Mortgages
Interest calculation accuracy for compound interest loans
Fixed incorrect interest calculation for loans with compound interest when principal overpayments were made.
Excess repayment validation with new loan balances
Corrected validation errors that occurred when processing excess repayments on accounts using the new loan account balance fields.
Overpayment validation for redraw accounts
Added proper payment amount validation for the Make overpayment action on accounts with redraw functionality.
Interest recalculation for backdated fee capitalization
Interest accrued is now correctly recalculated when fee capitalization transactions are posted with backdated effective dates.
Principal due rounding after interest rate changes
Resolved an issue where principal due amounts displayed incorrect rounding after interest rate changes were applied.
Days in arrears calculation accuracy
Fixed a calculation error where carried forward Days In Arrears values were reduced by one day incorrectly.
Loan product configuration updates in sandbox
Resolved an issue preventing loan product updates via PATCH requests in specific sandbox environments.
End of day processing stability
Fixed failures in the End of Day process caused by Interest Free Amount calculations in certain sandbox environments.
Fee interest calculations after partial payments
Corrected the calculation of returned accrued interest on interest-bearing fees following fee reductions or partial repayments.
Fee capitalization threshold enforcement
Fee capitalization transactions now properly respect configured thresholds when interest calculations are affected.
Interest due calculation precision
Resolved discrepancies in interest due calculations that resulted in incorrect payment amounts.
Custom repayment options after fee restructuring
Custom Repayment options for non-scheduled fees are now correctly available after carry forward scheduled fees restructuring operations.
Redraw accounting for interest-only loans
Fixed incorrect accounting entries for redraw repayments on Interest Only Equal Installment products when payment amounts exceeded the interest balance.
Due date validation for bulk updates
Bulk due date updates now properly validate against holiday schedules to prevent duplicate due dates across different installments.
Interest due accuracy after rate changes
When an interest rate change happens shortly after a custom principal repayment on loans configured with the "Principal expected is paid before/on due date" rule, the system incorrectly marked installments as fully paid by setting interest due to zero. The fix ensures interest due remains correctly open until its actual due date, improving amortization accuracy and payment amounts.
Payment holiday processing for interest-only loans
Corrected payment holiday behavior for Interest Only Installment loans to prevent them from processing as Interest Level Installment loans.
Reschedule validation with redraw balances
Fixed an issue where rescheduling a loan account with both an available redraw balance and an outstanding interest balance would fail. The system now correctly updates its record of the interest balance after the redraw balance is used to pay it down, but before validations are run.
Islamic Banking
Profit cycle account status handling
Resolved an issue where account status was incorrectly modified during profit cycle closure operations.
Average balance calculation accuracy
Fixed incorrect average balance calculations that affected profit distribution in specific monthly cycles.
Shari'ah product interface consistency
Interest-related fields are now properly hidden in the user interface when Shari'ah product categories are selected.
Account closure messaging
Corrected the wording displayed in confirmation dialogs when closing Investment Profit Sharing accounts.
Deposits
Monthly fee application with insufficient balance
The End of Day (EOD) process previously failed when attempting to apply monthly fees to a savings account with an insufficient balance, specifically when the German fee model was enabled and overdraft was disabled. The entire monthly fee is now correctly applied in this scenario, which may cause the account to go In Arrears if the balance is insufficient.
Product accounting rule updates
Fixed an issue where refreshing product accounting rules could incorrectly drop existing rules or mis-handle updated ones. The update ensures stable handling of edits and additions without unintended deletions.
Unicode character handling in account updates
If a user sets a unicode character in the Notes field for savings accounts, an exception is still thrown but with a response status code 400 instead of 500 as before.
Non-customer-facing deposits processing improvements.
