Introduction
Income recognition becomes important when a performing loan turns into a Non-Performing Asset (NPA).
While an account is Standard, interest is normally recognised on an accrual basis because collection is reasonably expected. Once the account becomes NPA, this principle changes.
RBI requires income recognition to be based on the record of actual recovery. Banks should not continue recognising interest on an NPA merely because interest is contractually accruing.
This creates three important numerical questions:
How much previously recognised interest must be reversed?
How should interest accruing after NPA classification be treated?
How much of a subsequent cash recovery can be recognised as income?
The 2026 IIBF BFM syllabus includes Asset Classification and Provisioning Norms under Module D, making these concepts relevant for calculation and case-based questions.
Learning Objectives
After studying this topic, you should be able to:
determine the unrealised income that must be reversed when an account becomes NPA;
distinguish accrued income from actually realised income;
understand the treatment of interest after NPA classification;
apply partial-recovery and appropriation principles;
identify exceptions involving moratorium and specified secured advances; and
avoid common calculation errors in CAIIB numerical questions.
Accrual Basis vs Realisation Basis
The starting point is the difference between a performing and non-performing asset.
Position | Income Recognition |
|---|---|
Standard Asset | Normally recognised on accrual basis |
NPA | Interest income recognised on actual realisation |
Interest accrued before NPA but still unrealised | Reversed |
Interest accruing after NPA | Not taken to P&L as income merely on accrual |
Actual interest recovery from NPA | May be recognised as income subject to RBI conditions |
RBI states that banks should not charge and take interest on an NPA to income merely on accrual. The rule also applies to Government-guaranteed accounts for income-recognition purposes.
Interest Reversal When an Account Becomes NPA
Suppose a bank has already credited interest to its Profit and Loss Account while the loan was treated as performing.
Later, the account becomes NPA.
If that credited interest remains unrealised, RBI requires it to be reversed. The rule applies to advances including bills purchased and discounted and also to Government-guaranteed accounts.
Interest to be Reversed = Accrued Interest Already Recognised as Income but Remaining Unrealised
This identifies the amount that should no longer remain in reported income after NPA classification.
Refer to the Formula Section for a detailed explanation, variables, and solved examples.
The key word is unrealised.
Interest that has genuinely been collected does not have to be reversed merely because the account subsequently becomes NPA.
Calculation Logic for Interest Reversal
In a CAIIB numerical, separate the interest into three buckets:
Bucket 1: Interest Already Realised
This is genuine income already collected.
Do not reverse it merely because the asset later becomes NPA.
Bucket 2: Interest Accrued and Credited to Income but Not Realised
This is the principal amount requiring reversal when the account becomes NPA.
Bucket 3: Interest Arising after the Account Becomes NPA
This should not normally be recognised in the Profit and Loss Account merely because it accrues.
RBI permits banks to keep track of such interest separately in a Memorandum Account. It should not be included in Gross Advances merely because it has been recorded there.
Effect on Profit and Loss Account
Interest reversal reduces previously reported income.
Therefore, when a loan becomes NPA:
Higher Unrealised Accrued Interest → Higher Reversal → Lower Reported Profit
This is why delayed recognition of stressed assets can distort profitability.
If a bank continues to recognise unpaid interest as income even after an account becomes NPA, its:
interest income may be overstated;
profit may be overstated; and
financial position may appear stronger than it actually is.
RBI’s prudential principle is therefore based on actual recovery rather than a subjective expectation of future payment.
Interest after NPA Classification
Once the account turns NPA, RBI requires banks to:
reverse interest already charged and not collected;
stop further application of such interest as recognised income; and
if desired, track accrued interest separately in a Memorandum Account.
A Memorandum Account helps the bank track what the borrower contractually owes without treating the amount as realised income.
Important Difference
Amount receivable from borrower ≠ Income recognised in P&L
The borrower may continue to be contractually liable for interest even though the bank is not permitted to recognise that interest as income on an accrual basis.
This distinction is important in numerical questions.
Partial Recovery from an NPA
A borrower may subsequently make a payment after the account has become NPA.
RBI permits interest actually realised from an NPA to be taken to income, provided the credit representing interest is not created out of a fresh or additional credit facility sanctioned to that borrower.
Thus:
Interest Income Recognisable from NPA = Genuine Cash Recovery Appropriated towards Interest
This identifies the amount that can return to income after actual recovery.
Refer to the Formula Section for a detailed explanation, variables, and solved examples.
The word genuine is important.
The bank cannot sanction fresh finance merely to generate an accounting credit and then claim that old interest has been recovered.
Appropriation of Recovery between Principal and Interest
Suppose an NPA has:
overdue principal;
unrealised interest; and
a subsequent recovery.
How should the recovery be divided?
If the agreement between the bank and borrower clearly specifies appropriation, the agreed treatment applies subject to the regulatory framework.
If there is no clear agreement, RBI requires the bank to follow an accounting principle for appropriation between principal and interest uniformly and consistently.
This is important because the amount appropriated towards interest can affect income recognition.
Numerical Approach
When a question gives a recovery from an NPA:
determine whether an appropriation rule is given;
identify the amount applied to principal;
identify the amount applied to interest;
recognise only the eligible realised-interest component as income; and
do not treat unpaid accrued interest as current income.
Fresh Finance Cannot Create Artificial Interest Recovery
Consider a borrower with substantial unpaid NPA interest.
The bank sanctions fresh additional finance and the amount is used to credit the old loan account.
The bank cannot automatically treat the credited amount as genuine interest recovery for income-recognition purposes.
RBI specifically conditions recognition of NPA interest recovery on the credit not being generated out of fresh or additional facilities sanctioned to the borrower.
This prevents artificial recognition of income.
Fees, Commission and Similar Income
The reversal principle is wider than ordinary loan interest.
For NPAs, RBI requires:
fees;
commission; and
similar accrued income
to cease accruing in the current period and to be reversed for earlier periods if still uncollected.
Therefore, a numerical question may include both:
accrued interest; and
uncollected fees or commission.
Do not calculate reversal using interest alone if the question specifically provides other uncollected accrued income.
Penal Charges on NPA Accounts
RBI has clarified that uncollected penal charges relating to an NPA should also be reversed for the purpose of non-recognition of income.
However, reversal from income does not automatically extinguish the borrower’s liability. Unless waived under the bank’s approved policy, the amount can remain part of the borrower’s liability.
This creates another useful distinction:
Income Reversal ≠ Waiver of Borrower Liability
The accounting treatment and legal/contractual amount recoverable are separate issues.
Government-Guaranteed Accounts
A Government guarantee does not permit a bank to recognise unrealised interest indefinitely.
RBI states that income recognition on Government-guaranteed advances follows the recovery principle.
Unrealised interest that has already been credited to income must be reversed where required, even though the account may receive special asset-classification treatment in certain Central Government-guaranteed cases.
This creates an important CAIIB distinction:
Asset Classification Treatment ≠ Income Recognition Treatment
A special exemption relating to classification does not necessarily permit accrual of unrealised income.
Advances against Specified Financial Assets
RBI provides a specific exception for advances against:
Term Deposits;
National Savings Certificates;
Kisan Vikas Patras; and
life insurance policies,
where adequate margin is available.
Interest on such advances may be taken to income on the due date subject to the specified conditions.
This rule should not be extended automatically to every fully secured advance.
The exception is specific.
Moratorium on Payment of Interest
Loans may contain a valid moratorium on interest payment.
Where the account continues to be classified as Standard, RBI permits income to be recognised on an accrual basis during the applicable moratorium, subject to the restructuring rules.
An important reversal exception also exists.
If:
the moratorium was permitted at the time of sanction; and
the loan becomes NPA after the moratorium period,
the capitalised interest corresponding to the interest accrued during that permitted moratorium need not be reversed merely because the account subsequently becomes NPA.
This is a high-value numerical trap.
Calculation Interpretation
If a question separates interest into:
interest accrued during a permitted sanction-stage moratorium; and
other unrealised interest,
do not automatically reverse the entire combined amount.
First apply the RBI moratorium exception.
Bills Purchased and Discounted
Income-reversal rules also apply when a bill purchased or discounted becomes NPA.
Any unrealised interest or discount that had already been credited to income requires the applicable reversal. RBI expressly includes bills purchased and discounted in its reversal rule.
Therefore, the concept is not restricted to ordinary term loans.
Leased Assets
For leased assets, the relevant finance-income component is important.
RBI provides that the finance charge component of finance income that had been recognised before the asset became NPA and remains unrealised should be reversed or provided for in the current accounting period.
The entire lease rental should therefore not automatically be treated as interest income.
Derivative Receivables and Income Reversal
Derivative contracts can also create unrealised income.
Where an overdue positive mark-to-market receivable becomes NPA under the applicable 90-day rule, RBI requires amounts already taken to the Profit and Loss Account to be reversed and held in the prescribed suspense treatment. Future positive MTM can also require suspense-account treatment rather than recognition in P&L.
For CAIIB, the conceptual lesson is:
Accrued derivative income that becomes non-performing cannot continue to inflate current profit merely because it was previously booked.
Current-Year and Earlier-Period Income
A numerical question may mention when the unrealised income was originally recognised.
The governing principle remains:
If income credited earlier remains unrealised when the advance becomes NPA, the applicable amount must no longer remain recognised as normal income.
Therefore, focus on:
amount accrued;
amount actually collected;
amount remaining unrealised; and
any specific RBI exception.
Do not reverse genuine collections.
Calculation Framework for CAIIB Questions
Use the following sequence.
Step 1: Identify the NPA Date
Determine when the account became NPA.
Only then can you separate pre-NPA and post-NPA interest correctly.
Step 2: Identify Income Already Credited
Find:
interest;
discount;
fees;
commission; and
similar income
already recognised before the NPA date.
Step 3: Determine Actual Realisation
Separate genuine cash recovery from merely accrued amounts.
Step 4: Calculate Unrealised Recognised Income
This is normally the key amount requiring reversal.
Step 5: Check Exceptions
Look for:
permitted moratorium;
specified advances backed by term deposits/NSCs/KVPs/life policies;
Government guarantee;
lease-finance treatment; or
other specifically stated regulatory conditions.
Step 6: Treat Post-NPA Interest Separately
Do not add it automatically to recognised income.
Step 7: Examine Subsequent Recovery
Determine how the recovery is appropriated between:
principal; and
interest.
Then identify the eligible realised-interest component.
Balance-Sheet and Profit Impact
Interest reversal affects more than one accounting figure.
When unrealised interest is reversed:
interest income falls;
profit before tax falls;
retained earnings may ultimately be affected;
reported asset quality becomes more realistic; and
the bank stops recognising uncertain income as earned profit.
Post-NPA interest recorded only in a Memorandum Account is not included in Gross Advances for the relevant regulatory computation.
This is why income recognition forms an important part of prudential banking.
CAIIB Exam Focus
1. Reverse Unrealised, Not Realised, Interest
If part of previously accrued interest has already been genuinely collected, focus on the amount still unrealised.
2. NPA Interest Is Not Recognised on Accrual Basis
Contractual accrual and accounting income are different once the asset becomes NPA.
3. Memorandum Interest Is Not Normal P&L Income
It may be tracked for recovery without being recognised as current income.
4. Recovery Must Be Appropriated Correctly
Do not automatically classify the full recovery as interest.
5. No Clear Appropriation Agreement Does Not Mean No Rule
The bank should follow a uniform and consistent accounting principle.
6. Fresh Finance Cannot Be Used to Manufacture Income
Interest recovery should not be treated as realised merely because new finance was used to credit the NPA account.
7. Fees and Commission Also Matter
Uncollected accrued fees, commission and similar income can require reversal.
8. Government Guarantee Does Not Override Income Recognition
Do not confuse asset-classification concessions with income-recognition rules.
9. Moratorium Has a Specific Exception
Capitalised interest relating to a permitted sanction-stage moratorium may not require reversal merely because the loan subsequently becomes NPA.
10. Reversal Does Not Mean Waiver
An amount removed from recognised income can still remain legally recoverable from the borrower.
Common Exam Traps
Trap 1: “All Interest Ever Charged Must Be Reversed”
Wrong. The focus is on interest previously recognised as income but remaining unrealised, subject to applicable exceptions.
Trap 2: “Interest Continues to Be Income after NPA because the Borrower Still Owes It”
Wrong. Contractual liability and income recognition are different.
Trap 3: “All Cash Recovery from an NPA Is Interest Income”
Wrong. Appropriation between principal and interest must first be determined.
Trap 4: “A Fresh Loan Used to Clear Interest Creates Genuine Income”
Wrong. RBI specifically restricts recognition where the apparent interest recovery arises from fresh/additional finance to the borrower.
Trap 5: “Only Interest Needs Reversal”
Wrong where uncollected fees, commission or similar accrued income is also present.
Trap 6: “Government Guarantee Allows Interest to Continue on Accrual”
Wrong. Income-recognition rules continue to apply.
Trap 7: “Interest Reversal Cancels the Borrower’s Liability”
Wrong. Accounting non-recognition is not the same as waiver.
Trap 8: “All Capitalised Moratorium Interest Must Always Be Reversed”
Wrong. RBI provides a specific exception for qualifying moratorium interest permitted at the time of sanction.
Memory Technique
Remember:
A – R – S – C
A = Accrued before NPA
R = Reverse if unrealised
S = Stop further accrual-based recognition
C = Cash recovery may be recognised when genuinely realised
For numerical questions, first split every interest figure into:
Realised | Unrealised | Post-NPA
That separation usually reveals the correct treatment.
