Asset Classification Norms for NBFCs: Standard, Sub-Standard, Doubtful and Loss

Updated 11 October 2026 · Fact-checked

NBFC asset classification sorts loans and other assets into standard, sub-standard, doubtful and loss assets based on how long they have been overdue and how well they can be recovered. An asset is an NPA once it is overdue for more than 90 days. Find the overdue period, apply the stage rule, then classify.

Understand Asset Classification Norms

An NBFC lends money, so some borrowers will not repay on time. The RBI requires every NBFC to sort its assets by credit quality. This sorting is the base for two later steps: stopping income recognition on bad assets and creating provisions against them.

There are four classes. A standard asset is one that does not show more than normal credit risk and is not an NPA. A non-performing asset (NPA) is an asset whose interest or principal is overdue for more than 90 days. Anything that is not an NPA is a standard asset.

NPAs are split into three. A sub-standard asset is one that has been an NPA for a period not exceeding 12 months. A doubtful asset is one that has remained sub-standard for more than 12 months. A loss asset is one identified as a loss by the NBFC, its internal or external auditor or the RBI, and not written off, or one considered uncollectible. Older ICMAI-style problems may describe doubtful assets by period (up to 1 year, 1 to 3 years, more than 3 years) because the provision rate depends on that period. Always follow the rule stated in the question.

For lease and hire purchase (HP) assets, the test is the overdue period of the lease rentals or HP instalments. Classification applies to the asset or the borrower account as the question directs. Once the 90 days limit is crossed the lease or HP asset becomes an NPA and then moves through the same sub-standard, doubtful and loss stages. Secured against unsecured status matters only for the provision rate, not for classification.

The key idea: classification depends on time overdue and recoverability. Provision percentages come later, in the provisioning topic. Do the classification first and do it right, because every later number depends on it.

Key rules to remember

NPA test: Overdue for more than 90 days → NPA; Overdue means principal or interest (or lease rental/HP instalment) not paid by its due date. Exactly 90 days is not yet an NPA; the test is more than 90 days.
Standard asset: Not an NPA → Standard asset; Includes all assets overdue for 90 days or less, provided there is no other sign of weakness stated in the question.
Sub-standard asset: NPA for ≤ 12 months → Sub-standard; The 12 months run from the date the asset became an NPA, not from the due date.
Doubtful asset: Sub-standard for > 12 months → Doubtful; Many problems split doubtful assets into up to 1 year, 1 to 3 years and over 3 years of doubtful status for provisioning.
Loss asset: Identified as loss by NBFC, auditor or RBI, not written off, or uncollectible → Loss; This is a judgement-based class. It does not depend only on time.
Timeline from due date: Date of NPA = due date + 90 days; Doubtful from = date of NPA + 12 months; Use this to place a year-end date on the correct side of each boundary.

How to solve Asset Classification Norms questions

Use this method for any question that asks you to classify NBFC assets or lease/HP accounts.

1Read the facts and note the balance sheet date and the due date of the earliest unpaid amount for each account.
2Count the days overdue as at the balance sheet date.
3If overdue is 90 days or less, mark it standard. If more than 90 days, mark it an NPA.
4For each NPA, find the date it became an NPA (due date + 90 days) and measure how long it has stayed an NPA at the balance sheet date.
5Mark NPAs of up to 12 months as sub-standard and those beyond 12 months as doubtful. Note the doubtful sub-period if the question gives period-wise rates.
6Check the facts for any sign of a loss asset: identified as uncollectible by the auditor, RBI or NBFC, or the security has become worthless.
7For lease and HP accounts, apply the same tests to the overdue rentals or instalments and keep the outstanding amount for the next step.
8Present the result in a small table with account, overdue period, class and reason, so the examiner can award marks for each step.

Quickest way: Date-line shortcut

When to use it: Use when several accounts are given with due dates and you need to classify them fast.

Draw one line with the balance sheet date at the right end.
Mark 90 days back as the standard/NPA line.
Mark 90 days plus 12 months back as the sub-standard/doubtful line.
Place each due date on the line to see its class at once.
Tag any account flagged as uncollectible as a loss asset regardless of position.

Common mistakes in Asset Classification Norms

Treating an account overdue for exactly 90 days as an NPA.
Students read the rule as 90 days or more.
Fix: The test is overdue for more than 90 days. At 90 days the account is still standard.
Counting the 12 months for sub-standard from the due date.
Students forget that the NPA period starts only after 90 days.
Fix: Find the NPA date first (due date + 90 days). Count 12 months from that date to decide sub-standard or doubtful.
Classifying a loss asset only by age.
The first three classes depend on time, so students assume the fourth does too.
Fix: Look for words like uncollectible, identified as loss by the auditor, or security value nil. Those facts make it a loss asset.
Mixing classification with provisioning, quoting provision rates as part of the class.
Both topics appear in the same chapter and the same question.
Fix: Classify first on time and recoverability. Apply provision rates in a separate step.
Ignoring lease and HP accounts, or classifying them on the whole contract value.
Students think lease and HP are a different regime.
Fix: Apply the same overdue tests to unpaid rentals or instalments of that account, and carry the outstanding amount forward.

Worked examples

Example 1

An NBFC has the following loan accounts as at 31 March 2027. Classify each. (a) Instalment of ₹2,00,000 due on 15 January 2027, unpaid. (b) Instalment due on 31 October 2025, unpaid. (c) Instalment due on 31 December 2026, unpaid. (d) Instalment due on 30 September 2024, unpaid; the auditor has identified the amount as uncollectible.

Show the solution

Account (c): due 31 December 2026. Days to 31 March 2027 = 31 (Jan) + 28 (Feb) + 31 (Mar) = 90 days. Overdue is exactly 90 days, not more than 90, so it is standard.
Account (a): due 15 January 2027. Days to 31 March 2027 = 16 (rest of Jan) + 28 + 31 = 75 days. This is 90 days or less, so it is standard.
Account (b): due 31 October 2025. Days overdue far exceed 90. NPA date = 31 October 2025 + 90 days = 29 January 2026. NPA period to 31 March 2027 is about 14 months, which is more than 12 months. So it is doubtful.
Account (d): overdue for a long time and the auditor has identified it as uncollectible. This makes it a loss asset.

Answer: (a) Standard, 75 days overdue. (b) Doubtful, NPA for more than 12 months. (c) Standard, exactly 90 days overdue. (d) Loss asset, identified as uncollectible by the auditor.

Example 2

A leasing NBFC reports the following lease rentals unpaid as at 31 March 2027: Lessee P, rental due on 1 November 2026; Lessee Q, rental due on 1 January 2026; Lessee R, rental due on 1 February 2027. Classify each lease asset as standard, sub-standard or doubtful. Assume none is identified as a loss asset.

Show the solution

Lessee R: due 1 February 2027. Days from 1 February 2027 to 31 March 2027 = 28 (February, up to 1 March) + 30 (1 March to 31 March) = 58 days (59 if you count the due date as well). Either way it is 90 days or less, so it is standard.
Lessee P: due 1 November 2026. Days to 31 March 2027 = 29 (Nov) + 31 (Dec) + 31 (Jan) + 28 (Feb) + 31 (Mar) = 150 days, which is more than 90. So it is an NPA.
For P, NPA date = 1 November 2026 + 90 days = 30 January 2027. NPA period to 31 March 2027 is about 2 months, which is within 12 months. So it is sub-standard.
Lessee Q: due 1 January 2026. NPA date = 1 January 2026 + 90 days = 1 April 2026. The asset completes 12 months as an NPA on 31 March 2027, which is not more than 12 months. So at 31 March 2027 it is still sub-standard. It turns doubtful from 1 April 2027 if it is still unpaid.

Answer: Lessee R: standard. Lessee P: sub-standard. Lessee Q: sub-standard at 31 March 2027, turning doubtful from 1 April 2027 if still unpaid.

Exam tips

Write the due date, balance sheet date and days overdue for every account. Marks are given for the working, not just the label.
Treat the boundaries carefully: more than 90 days for NPA, and more than 12 months as NPA for doubtful.
In MCQs, look for a single fact that decides the class, such as the auditor identifying a loss or exactly 90 days overdue.
Use the classification table as the first step of any provisioning problem and carry the outstanding balances into it.
If a question states its own period rules, follow them over what you remember.

Asset Classification Norms: frequently asked questions

What is the NPA definition for NBFCs in the exam?

An asset is an NPA when its principal or interest is overdue for more than 90 days. Assets overdue for 90 days or less are standard unless the question gives another reason for treating them as weak.

What is the difference between sub-standard and doubtful assets in an NBFC?

A sub-standard asset has been an NPA for up to 12 months. A doubtful asset has stayed in the sub-standard category for more than 12 months. Doubtful assets also carry higher provisions.

How are lease and HP assets classified?

They follow the same overdue tests. Unpaid lease rentals or HP instalments beyond 90 days make the asset an NPA, and it then moves through sub-standard, doubtful and loss stages with time and recoverability.

What makes an asset a loss asset?

An asset is a loss asset when it is identified as a loss by the NBFC, its auditor or the RBI and has not been written off, or when it is considered uncollectible. It is a judgement-based class, not just a time-based one.
