NPA Classification 2026: Provisioning Norms for CAIIB ABM
NPA classification — this guide gives you the latest 2026 understanding of how banks identify non-performing assets and set aside provisions against them. We cover the asset categories, the provisioning logic, income recognition, and exactly what CAIIB Advanced Bank Management candidates must remember.
For students of the CAIIB Advanced Bank Management paper, NPA classification and provisioning sit at the heart of asset quality. They determine how a bank reports its health, how much profit it can recognise, and how much capital it must hold, so a banker who masters the framework reads a balance sheet with real insight.
In this guide we unpack what makes a loan an NPA, the sub-categories of impaired assets, the income-recognition rule, and the provisioning approach that protects a bank against expected losses.
What NPA Classification Means
NPA classification is the process by which a bank identifies loans that have stopped performing and groups them by the degree of impairment. A non-performing asset is broadly an advance where interest or principal has remained overdue for more than ninety days, at which point the bank can no longer treat it as a normal earning asset. The ninety-day overdue benchmark is the central trigger to remember.
The purpose of NPA classification is prudence and transparency. By recognising stress early and consistently, a bank presents a true picture of its asset quality to regulators, investors and its own management, and it builds the cushions needed to absorb likely losses. The framework follows the prudential norms on income recognition, asset classification and provisioning.
For a banker, the relevance is direct: classification drives provisioning, which hits the profit-and-loss account and capital. Understanding the trigger and the categories is essential for credit monitoring and for ABM exam questions alike. Reinforce the fundamentals with our CAIIB mock tests.
The Categories of Assets Under Classification
Under NPA classification, assets are first split into standard and non-performing. A standard asset carries no problem beyond normal business risk and is performing. Once an account becomes an NPA, it is further graded by how long it has stayed impaired and the prospects of recovery.
The non-performing categories are sub-standard, doubtful and loss. A sub-standard asset is one that has remained an NPA for up to a defined period after the ninety-day trigger; a doubtful asset is one that has stayed sub-standard beyond that period, where recovery is questionable; and a loss asset is one identified as uncollectible, where little or no recovery is expected though it may not yet be fully written off.
This graded structure matters because the worse the category, the higher the provision required. For the ABM exam, memorise the progression from standard to sub-standard to doubtful to loss, and the idea that time in default and security cover together drive the grade.

Income Recognition on Non-Performing Assets
A key principle linked to NPA classification is income recognition. Once an advance is classified as non-performing, the bank must stop recognising interest on it on an accrual basis, because that interest is not actually being received. Recognising unrealised interest as income would overstate profit and mislead users of the accounts.
Instead, income on an NPA is recognised only when it is actually received, on a realisation basis. Any interest previously booked but not collected on an account that turns into an NPA must be reversed if it remains unrealised. This conservative treatment ensures that reported profit reflects genuine earnings rather than paper accruals.
For the ABM exam, be ready to explain why interest accrual stops at classification and how the realisation basis works thereafter. This is a frequently tested point because it links asset quality directly to the profit-and-loss statement. Any current numerical thresholds evolve with regulation, so verify live reference data on our RBI rates and reference page.
Provisioning Norms Against Expected Losses
Provisioning is the amount a bank sets aside from profits to cover expected losses on its loans, and it follows directly from NPA classification. Even standard assets attract a small general provision, reflecting the normal risk in any portfolio. Non-performing assets attract progressively higher provisions as they move from sub-standard to doubtful to loss.
The logic is straightforward: the weaker the asset and the poorer the security cover, the larger the provision needed. Sub-standard assets require a moderate provision, doubtful assets require higher provisions that increase with the time spent doubtful and distinguish the secured from the unsecured portion, and loss assets require full provisioning since they are treated as uncollectible. The exact percentages are set by the regulator and are revised from time to time.
For the ABM exam, understand the principle that provisioning rises with deterioration, rather than memorising volatile percentages in isolation. Be ready to explain how provisioning protects depositors and the bank's capital, and why early, honest classification keeps a bank resilient. Explore more bank-management guides on our blog.
Exam Strategy for Advanced Bank Management Candidates
NPA classification questions in ABM test the ninety-day trigger, the four asset categories, the income-recognition rule, and the principle that provisioning rises with deterioration. Build a one-page ladder from standard to loss with the provisioning logic beside each rung, and revise the realisation-basis rule until it is automatic.
Pair conceptual study with timed practice and review your weak areas after each attempt, since ABM rewards precise recall of the prudential framework. Keep your fundamentals sharp through regular drills, and explore more guides on our blog to round out your preparation across the syllabus.

Frequently Asked Questions
When does a loan become a non-performing asset?
A loan generally becomes a non-performing asset when interest or principal remains overdue for more than ninety days. For certain facilities like cash credit, the account is treated as an NPA if it remains out of order beyond the prescribed period. The ninety-day benchmark is the core trigger.
What are the categories of non-performing assets?
NPAs are graded as sub-standard, doubtful and loss assets. A sub-standard asset has been an NPA for a limited period, a doubtful asset has stayed sub-standard beyond that with uncertain recovery, and a loss asset is considered uncollectible. The grade reflects time in default and recovery prospects.
Why does interest accrual stop on an NPA?
Once a loan is classified as non-performing, the bank stops recognising interest on an accrual basis because it is not actually being received. Booking unrealised interest would overstate profit, so income is recognised only when realised, and previously booked unrealised interest is reversed.
How does provisioning relate to asset classification?
Provisioning is the amount set aside from profit to cover expected losses, and it rises as an asset deteriorates. Standard assets attract a small general provision, while sub-standard, doubtful and loss assets attract progressively higher provisions, with loss assets fully provided for.
