Investor Due Diligence
Also written IDD/DDR · Investor Due Diligence (IDD/DDR) · IDD · DDR · Fund due diligence · Investment due diligence · Due diligence report · Investor Due Diligence (IDD or DDR)
The investigation an investor runs on an AIF and its manager before committing capital — the process of investigation and evaluation into the details of a potential investment.
In plain language
AIF products are marketed privately and are meant for informed investors. There is no prospectus, no listed price, no analyst coverage. The regulator's bargain is that such investors are expected to conduct their own due diligence before investing.
So the phrase means something particular here. Fund due diligence is conducted by the investor, on the fund and its manager — not by the manager on an investee company, which is a separate exercise entirely. And because information on AIFs is not publicly available, the PPM is the main source, supplemented by whatever the investor can extract from the fund house directly.
The workbook is blunt about the payoff: managing this activity is seen as the main source of competitive advantage for a potential investor.
How it works
The four-step approach to fund selection. Quantitative selection — a template of objective criteria (investment horizon, hurdle rate, past performance, capital commitment, drawdown phase) that narrows the field. Investment management team and infrastructure — interviews and background checks, whether the team has enough macro, equity and credit analytical support, whether the organisation has processes to institutionalise the management function, and whether staffing and compensation are adequate. Investment process review — sourcing through to exit, the decision-making process, checks and balances, research quality and risk management. Past performance review — peer comparison and benchmarking against listed markets to see whether alpha is real and consistent with the stated philosophy.
Then sixteen areas of investment due diligence, of which the examinable ones are: investment strategy (short positions, derivative use, concentration limits, illiquidity, and for Category III, leverage); the management team; the fee structure, where a higher fee must be justified by past performance and reputation; hurdle rate and target returns; risk factors and leverage; risk management controls; government reforms and taxation; macro-economic factors; regulatory compliance and legal proceedings; business operations and internal controls including maker-checker; third-party service providers and their related-party conflicts; business continuity and disaster recovery; ESG policies; potential conflicts of interest; transparency and investor reporting; and on-site visits.
Two lookbacks are numeric. Historical performance of funds previously managed should be analysed over a minimum of five years. And the manager, sponsor, their partners, directors, associates and trustees should have no history of outstanding litigation where the person has been found guilty, for a minimum period of five years.
Timing is the leverage. Due diligence should ideally be completed before signing legal documents and investment agreements. Complete it in time and the findings become negotiating material for the subscription terms; complete it late and they are merely regrets.
A worked example
Kalinga Family Office is evaluating Nalanda Private Credit Fund II, a Rs 800 crore Category II AIF, for a Rs 25 crore commitment.
Its diligence produces four findings and uses each one:
| Finding | What it did with it |
|---|---|
| Track record on Fund I covers only 3 years, not 5 | Asked for deal-level realised and unrealised marks, and for the two written-off positions |
| Management fee quoted at 2.00% on commitments | Negotiated 1.75%, and a step-down to invested capital after year 3 |
| Set-up cost 2.5% of commitments, unamortised in year 1 | Negotiated amortisation over 36 months |
| A group entity of the sponsor is the fund administrator | Asked for the related-party fee schedule and a cap |
What the fee negotiation alone was worth:
25 bps saved on Rs 25 crore commitment = Rs 6.25 lakh per year
Over a 3-year commitment period = Rs 18.75 lakh
Plus the step-down, years 4-8, on roughly
Rs 19 crore invested rather than Rs 25 crore
at 1.75% = Rs 10.5 lakh per year
Total saved over the fund life ~ Rs 71 lakh
On a Rs 25 crore commitment that is nearly 3%, recovered before the fund made a single investment — and unavailable the moment the contribution agreement was signed.
What the diligence could not do was tell Kalinga whether Fund II will perform. That is why the workbook warns that the high reliance on qualitative aspects and judgement can obscure genuinely good opportunities: newer AIFs are avoided not because the fundamentals are wrong but because not every point can be supported by tangible evidence.
Why NISM asks about it
Chapter 12 (Fund Due Diligence – Investor Perspective) is the chapter, with section 12.1 on scope and uniqueness, 12.2 on the sixteen areas, 12.3 on manager evaluation and 12.4 on manager selection. Chapter 11 lists investor due diligence among its learning objectives. Expect questions on who conducts due diligence and on whom, and a 'which of these is a criterion for evaluating a fund manager' question.
Common exam traps
- Fund due diligence is by investors on the AIF. Due diligence on the investee company is the manager's job, and a question that swaps the two is the commonest trap in this chapter.
- Another institution's commitment is not your diligence. The workbook says so explicitly: investors should not take comfort from a large institution having committed capital.
- The PPM is the main source, not the only one. Additional information has to be collected from the fund house, and on-site visits are part of the list.
- Five years, twice — minimum five years of track record, and no adverse finding for a minimum period of five years on disciplinary history.
- Finish before signing. Diligence completed after execution buys nothing, because the negotiating window has closed.
- Due diligence operates at two levels — fund level (operational, market, regulatory, strategy and reputational risk) and investee company level (financial and business).
Where this is taught
Free preparation for NISM Series XIX-DRelated terms
- Private placement memorandumThe offer document of a Category III AIF, filed with SEBI through a merchant banker at least 30 days before a scheme launches — and the document SEBI comments on but never approves.
- Continuing interestThe sponsor's or manager's own money locked into the fund — 2.5% of corpus or Rs 5 crore, whichever is lower, for Category I and II AIFs, and 5% or Rs 10 crore for Category III.
- Hurdle rateThe minimum return that must accrue to investors before the manager earns any incentive fee — the threshold that turns a fund's profit into the manager's profit.
- Management FeeThe fixed annual fee an AIF pays its investment manager for managing the fund — charged on committed capital in Category I and II funds and on gross NAV in Category III, regardless of performance.
- Adverse selectionThe risk of ending up with the wrong manager — picking a fund on a track record or a forward-looking statement that does not predict performance, and getting sub-optimal returns or moral hazard instead.
- Concentration riskThe risk that a few positions are large enough, against the fund's capital, that one loss damages the whole portfolio — capped by SEBI at 25% of investable funds for Category I and II AIFs and 10% for Category III.
- Cyber Security RiskThe risk that an AIF's or its service providers' systems are breached, corrupted or disrupted — governed by SEBI's Cyber Security and Cyber Resilience Framework, which all AIFs had to comply with by 31 August 2025.
