How to Evaluate an NCD Issue Before Subscribing in India

Imagine this: a well-known NBFC launches a public NCD issue offering 9.4% per annum, and your inbox fills up with forwarded WhatsApp messages from family members asking whether to subscribe. The coupon sounds attractive, the company name is familiar, and the issue closes in four days. How do you cut through the noise and make a considered decision rather than an impulsive one?

This guide walks you through a structured, step-by-step framework for evaluating any NCD issue before you put money in. We cover the eight dimensions that matter most — credit rating, collateral, issuer financials, yield comparison, issue structure, liquidity prospects, taxation, and red flags — so that by the time an NCD lands in your inbox, you have a clear checklist rather than a guessing game. We also highlight the most common mistakes first-time NCD subscribers make, and answer the questions we hear most often.

Key Takeaways

Credit rating is your first filter, not your only filter — a minimum of AA (stable) from at least two accredited agencies is a widely used baseline; understand what the rating covers and when it was last reviewed.
Secured NCDs rank ahead of unsecured NCDs in recovery — always check the type of security, asset cover ratio, and whether the charge is exclusive or pari-passu with other lenders.
Compare yield-to-maturity, not just the coupon rate — the coupon printed in the advertisement may be annual, but you need the actual YTM across the exact series you are considering; a YTM walkthrough helps you do this correctly.
Issuer financials deserve at least 15 minutes of reading — focus on debt-to-equity, interest coverage ratio, and NPA levels for NBFCs; a one-year snapshot is not enough.
Check the prospectus for use-of-proceeds and covenants — money raised to refinance existing debt is not inherently bad, but layering more debt on a stressed balance sheet is a warning signal.
Secondary market liquidity is often thin for NCDs — plan your holding period realistically; exiting before maturity can mean selling at a significant discount.
Tax treatment affects your effective return meaningfully — interest from NCDs is taxable at your slab rate; understanding bond interest taxation before subscribing helps you calculate post-tax yield accurately.
Diversify across issuers and maturities — even a high-quality NCD should not constitute more than 5–10% of your fixed-income allocation; no single issuer exposure eliminates concentration risk.

Step 1: Start With the Credit Rating — and Read Beyond the Grade

When a new NCD issue is announced, the rating is the first piece of information most investors look at. A CRISIL AA+ or ICRA AA will appear prominently on marketing materials. But the letter grade is only the beginning.

Understand what the rating actually covers

Credit ratings assess the issuer's ability to service debt on time. They do not assess whether the yield offered is fair relative to risk, whether the bond will be liquid in the secondary market, or whether the collateral is realistically recoverable.

Check the rating from multiple agencies

SEBI mandates that public NCD issues obtain ratings from at least one registered Credit Rating Agency (CRA). However, issues rated by two agencies give you a cross-check. If one agency assigns AA and another assigns A+, the divergence itself is informative — read both rationale documents to understand why. Our credit ratings explained guide covers how rating scales work across agencies.

Look at the rating outlook and history

A rating of AA (Negative Watch) is meaningfully different from AA (Stable). Download the rating rationale from the CRA's website and look for:

Whether the outlook is positive, stable, or negative
Whether the rating has been downgraded in the past 24 months
Key concerns the analyst has flagged even at the current grade

A company rated AA today but downgraded from AAA eighteen months ago warrants deeper scrutiny than one that has held AA (Stable) for five years.

Step 2: Examine the Collateral — Secured vs Unsecured

Not all NCDs are created equal when it comes to what you can recover if the issuer runs into trouble. The distinction between secured and unsecured bonds has real, quantifiable consequences.

Secured NCDs

A secured NCD is backed by a charge on specific assets of the issuer — typically receivables, property, or equipment. If the issuer defaults, secured NCD holders have priority access to those assets in the resolution process.

Key questions to ask:

Question	Where to Find the Answer
What assets secure the NCD?	Prospectus, "Security" section
Is the charge exclusive or pari-passu?	Prospectus, trust deed summary
What is the asset cover ratio?	Prospectus, financial disclosures
Who is the debenture trustee?	Prospectus, front page

SEBI mandates a minimum asset cover of 1x for secured NCDs, but a higher ratio — 1.5x or above — offers a more meaningful buffer.

Unsecured NCDs

Unsecured NCDs carry no charge on assets. If the issuer defaults, unsecured NCD holders join a queue behind secured creditors, banks, and the government as a tax authority. Recovery in such scenarios has historically been poor, which is why unsecured NCDs typically offer a higher coupon. The extra yield is compensation for standing at the back of the recovery line.

Conditional framing: If capital preservation matters more than maximising coupon income, secured NCDs with strong asset cover ratios deserve priority in your evaluation.

Step 3: Analyse the Issuer's Financial Health

A rating tells you what analysts thought at the time of their last review. Issuer financials let you form your own view and spot trends that may not yet be reflected in the rating.

For NBFCs (the most common NCD issuers)

NBFCs dominate India's NCD market. When evaluating an NBFC issuer, focus on:

Debt-to-Equity Ratio: A D/E above 6–7x for a retail NBFC, or above 4x for a housing finance company, warrants explanation. High leverage amplifies stress during liquidity crunches.

Gross and Net NPA Levels: Rising non-performing assets are a leading indicator of future stress. Compare NPA trends over three years, not just the most recent quarter.

Interest Coverage Ratio: This measures how comfortably the issuer can service interest from operating earnings. An ICR below 1.5x leaves little room for error.

Capital Adequacy Ratio (CAR): NBFCs are required to maintain a minimum CAR. A CAR significantly above the minimum suggests a cushion; one close to the floor suggests the company is running lean.

Liquidity Position: Check whether the issuer has undrawn credit lines, liquid investments, or a diversified funding mix. Excessive dependence on short-term borrowings to fund long-term assets (asset-liability mismatch) is a classic stress trigger — IL&FS and DHFL illustrated this vividly.

For other corporate issuers

Look at free cash flow generation, EBITDA margins, and debt-service coverage ratios. Check whether the use-of-proceeds section in the prospectus describes productive deployment (capital expenditure, business expansion) or primarily debt refinancing. Refinancing existing debt is not automatically bad, but if it represents the sole use of proceeds and leverage is already elevated, it deserves caution.

Familiarise yourself with the warning signs of bond defaults to build a mental model of what deteriorating credit looks like before it reaches a rating action.

Step 4: Evaluate the Yield — Properly

The coupon rate on an NCD advertisement is not the same as your effective return. Evaluating yield correctly requires understanding three numbers:

Coupon Rate vs Current Yield vs YTM

Coupon Rate: The interest rate printed on the bond, applied to face value.
Current Yield: Annual coupon income divided by the price you actually pay.
Yield to Maturity (YTM): The total annualised return if you hold the bond to maturity, accounting for the purchase price, coupon payments, and redemption at par.

For primary NCD issues, the price is typically par (Rs. 1,000 face value), so the coupon rate and YTM are close. But some issues offer Series A at 36 months and Series B at 60 months with different coupons. Compare YTMs across series, not just coupons.

Benchmark against G-Secs and AAA bonds

A useful exercise before subscribing is to check what the yield spread looks like:

Benchmark	Indicative Yield (June 2026)
10-Year G-Sec (conventional risk-free reference)	~7.1%
AAA-rated corporate NCD (3–5 year)	~7.8–8.2%
AA-rated NCD (3–5 year)	~8.5–9.0%
A-rated NCD (3–5 year)	~9.5–10.5%

Yields are illustrative and subject to market conditions.

If an AA-rated issuer is offering 11%, ask why. Either the market is demanding a premium for issuer-specific concerns not yet captured in the rating, or there is a structural feature (such as subordination) that makes the bond riskier than the rating implies. Either way, the anomaly deserves investigation, not celebration.

Account for post-tax yield

NCD coupon income is taxed as "Income from Other Sources" at your marginal slab rate — 30% plus surcharge and cess for the highest earners. A 9.5% pre-tax coupon becomes approximately 6.5% post-tax for someone in the 30% bracket. Compare this with post-tax returns from alternatives like fixed deposits, AAA-rated bonds, or tax-free bonds before concluding that the NCD offers superior value.

Step 5: Understand the Issue Structure

The prospectus for a public NCD issue is a legal document that most investors skip. You do not need to read all 300 pages, but several sections are critical.

Key sections to review

Series and Tenor Options: Most issues offer multiple series across different maturities and payment frequencies (annual, cumulative). Identify which series aligns with your cash-flow needs and investment horizon.

Redemption and Put/Call Options: Some NCDs carry call or put options that allow the issuer (call) or investor (put) to redeem before maturity. A call option benefits the issuer in a falling rate environment — they redeem your high-coupon bond and refinance cheaper. Understand how this affects your holding period assumptions.

Payment Frequency: Quarterly coupon payments suit investors who need regular income. Annual or cumulative options suit those who prefer reinvesting or deferring tax. Cumulative NCDs are taxed on accrual in certain structures — verify with your tax adviser.

Allotment Basis: If the issue is oversubscribed (which happens with reputable issuers), you may receive only partial allotment. Plan for this possibility before blocking funds.

Lock-in and Listing: Public NCD issues are mandatorily listed on BSE or NSE within a specified number of days after allotment. Listing does not guarantee liquidity, but it at least provides an exit mechanism — which unlisted private placement NCDs do not.

Step 6: Assess Liquidity Realistically

Many retail investors treat NCDs like fixed deposits: buy and hold to maturity, collect interest, done. If that genuinely reflects your plan, illiquidity is manageable. But life changes — job loss, medical expense, a better opportunity — and having a realistic picture of exit options matters.

Secondary market liquidity for NCDs on Indian exchanges varies dramatically:

Large NBFC issuers (Bajaj Finance, Shriram Finance, Tata Capital): Relatively tradeable, though bid-ask spreads of 30–80 bps are common.
Mid-tier issuers: May trade sporadically; finding a buyer in reasonable time at a fair price is not guaranteed.
Smaller or less-known issuers: Effectively illiquid in the secondary market for most practical purposes.

If you anticipate needing liquidity before maturity, factor in the likely exit cost. Our guide on exiting a bond before maturity explains the mechanics and costs of secondary market exits.

Conditional framing: If your investment horizon is fixed and certain — say, a five-year window before a specific financial goal — and the NCD tenor matches, illiquidity is a non-issue. If your horizon is uncertain, prioritise either liquid instruments or shorter-tenor NCD series.

Step 7: Complete Your Demat and Application Checklist

NCD subscriptions in public issues require a demat account linked to your PAN. Applications are made through your bank's ASBA facility or through brokers supporting UPI mandates for bond applications.

Before the issue opens, verify:

Your demat account is active and KYC-compliant with your DP
Your bank account supports ASBA for the application amount
You have noted the issue open and close dates
The minimum application amount and lot size (typically Rs. 10,000 or 10 bonds at Rs. 1,000 face value each)

If you have not yet set up your demat account for bond investing, our bond KYC and demat setup guide covers the end-to-end process.

Common Mistakes NCD Investors Make

Relying solely on the brand name of the issuer. A recognisable corporate name provides comfort, not safety. DHFL and IL&FS were well-known entities before their defaults. Brand recognition is not a substitute for financial analysis.
Chasing the highest coupon without checking the rating and security. A 12% coupon from an unrated or BB-rated issuer is not a bargain — it is compensation for significantly elevated default risk. Yield and risk move together; they cannot be separated.
Ignoring the tax impact on effective returns. Comparing a 9% NCD coupon (pre-tax) with a 7% G-Sec yield (also pre-tax) without adjusting for slab rate taxes creates a misleading picture. For investors in the 30% bracket, post-tax NCD yield may be barely above the G-Sec.
Assuming listing equals liquidity. A listed NCD can remain untradeable for weeks if demand from secondary market buyers is absent. Do not interpret "listed on NSE/BSE" as a promise of easy exit.

Frequently Asked Questions

What is the minimum investment amount for a public NCD issue?

Most public NCD issues set a minimum application of 10 bonds at Rs. 1,000 face value each, making the minimum investment Rs. 10,000. Some issues may set a higher floor. The prospectus specifies the minimum lot size and the allotment structure for different investor categories (retail individual investors, high-net-worth individuals, and institutional investors each have separate portions).

How is NCD interest taxed in India?

Interest income from NCDs is classified as "Income from Other Sources" and taxed at your applicable income tax slab rate. For individuals in the 30% bracket, this means an effective tax of approximately 31.2% (including cess). Capital gains from selling listed NCDs held for more than 12 months are taxed at 12.5% without indexation. Short-term capital gains (held under 12 months) are taxed at your slab rate. Our bond interest taxation guide covers these rules in detail with worked examples.

What does "secured" mean in an NCD context, and how much does it matter?

A secured NCD has a legal charge over specified assets of the issuer — typically a pool of receivables, property, or equipment. The charge is managed by a debenture trustee who represents NCD holders. In the event of default, secured holders have a priority claim on those assets over unsecured creditors. This does not guarantee full recovery — asset values can deteriorate, and resolution takes time — but it materially improves the odds compared to unsecured holders, who rank lower in the creditor waterfall.

Can I exit an NCD before maturity?

If the NCD is listed on a stock exchange, you can sell it in the secondary market through your broker, subject to finding a willing buyer at an acceptable price. Thin liquidity means you may need to accept a price below fair value, especially for smaller or less-traded issuers. If the NCD has a put option, you can exercise it on the specified put date to redeem at a predetermined price. Unlisted NCDs have no formal exit mechanism before maturity. Our article on exiting a bond before maturity covers each scenario.

Is applying to an NCD issue different from buying in the secondary market?

Yes, in important ways. In a primary issue, you apply during the subscription window, funds are blocked via ASBA, allotment happens after the issue closes, and bonds are credited to your demat before listing. You do not pay accrued interest and generally subscribe at par (face value). In the secondary market, you buy from an existing holder at a market price that may be above or below par, you pay accrued interest since the last coupon date (the dirty price), and settlement typically follows the T+1 cycle. Primary market subscriptions offer certainty of price but uncertainty of allotment quantity.

How do I find the prospectus for an NCD issue?

The full prospectus (also called the Prospectus or Information Memorandum) is filed with SEBI and the stock exchanges where the NCD will be listed. You can download it from the BSE or NSE website by searching the company name under the "Corporate Filings" or "Offer Documents" section. The prospectus is also available on the company's investor relations page and on the websites of the lead managers to the issue. Reading even the first 30 pages — the executive summary, risk factors, and financial highlights — significantly improves the quality of your evaluation.

Bottom Line

Evaluating an NCD issue is not as daunting as it might appear, but it does require more than glancing at the coupon rate. Work through the checklist systematically: start with the credit rating and read the rationale, not just the grade; verify the collateral type and asset cover; spend 15 minutes on the issuer's financials; calculate post-tax YTM and compare it against appropriate benchmarks; understand the issue structure and your realistic exit options. If after this process the risk-return proposition still looks compelling relative to your investment horizon and tax situation, you are in a much stronger position than the investor who subscribed based on a WhatsApp forward.
