Interest in Suspense

Overview

Interest in Suspense (IIS) is an accounting treatment applied to non-performing loans (NPLs) where accrued interest income is no longer recognized in the income statement. Instead, interest is moved to a suspense account until the loan is either recovered or written off.

This is a regulatory requirement in most financial jurisdictions (e.g., IFRS 9, Basel III, Central Bank prudential guidelines) to ensure that income statements do not reflect interest income that is unlikely to be collected.

Key Concepts

When to Suspend Interest

Interest should be moved to suspense when:

• Arrears threshold: A loan exceeds the institution's NPL classification threshold (typically 90+ days past due)
• Regulatory classification: The loan is classified as substandard, doubtful, or loss
• Account closure: The account is closed with outstanding interest
• Manual decision: A credit officer or risk manager determines the interest is unlikely to be collected

Suspense Reasons

Reason	Description
ARREARS	Loan exceeded days-in-arrears threshold
NPL_CLASSIFICATION	Loan classified as non-performing
REGULATORY	Regulatory or central bank requirement
ACCOUNT_CLOSED	Account closed with outstanding interest
MANUAL	Manual adjustment by authorized user

Suspense Statuses

Status	Description
SUSPENDED	Interest is currently in suspense
PARTIALLY_RELEASED	Part of the suspended balance has been released
RELEASED	Interest has been released back to income (loan recovered)
WRITTEN_OFF	Interest has been written off (loan loss)

Operations

Moving Interest to Suspense

1. Navigate to Loan Accounts > Operations > Interest Suspense
2. Click Move to Suspense
3. Select the loan account
4. Enter the amount to suspend
5. Choose the suspension reason
6. Add any notes
7. Submit

For batch operations, use the batch mode to suspend interest on multiple accounts at once.

Releasing Interest from Suspense

When a previously non-performing loan recovers (e.g., borrower makes payments and the loan becomes current again):

1. Find the suspended interest record in the table
2. Click the Release action
3. Confirm the release amount (defaults to full suspended amount)
4. The interest is credited back to interest income

The GL posting uses the LOAN.INT.SUSPEND and LOAN.INT.SUSPEND.RELEASE rules, with the suspense leg resolved through the LOAN_INTEREST_SUSPENSE_COA tag.

Integration with Daily Processes

Arrears Engine

The update_arrears_status batch procedure updates loan arrears buckets. Loans that cross the NPL threshold (e.g., L4_90_PLUS) can be flagged for automatic interest suspension via the early warning flags system (HIGH_DPD flag).

Interest Accrual

The accrue_loan_interest procedure continues to accrue interest on loans in arrears by default (controlled by the accrue_late_interest product flag). When interest is suspended:

• Accrual continues to track the economic interest owed
• The suspense entry reverses the income recognition
• This maintains the correct receivable balance while removing income inflation
