17.1.1 Who must register, and in which category
On and from the commencement of these Regulations, all existing and proposed AIFs that are domiciled in India by virtue of being incorporated in India are subject to COMPULSORY REGISTRATION with SEBI. Existing schemes will be allowed to complete their agreed tenure, however, SUCH FUNDS SHALL NOT RAISE ANY FRESH MONIES other than commitments already made till registration is granted.
The funds registered as venture capital fund under SEBI (Venture Capital Funds) Regulations, 1996 — desirous of migrating to SEBI (AIF) Regulations may seek registration... as MIGRATED VENTURE CAPITAL FUND subject to approval of TWO-THIRDS of their investors by value of their investment within JULY 19, 2025.
The four categories
1. Category I Alternative Investment Fund — invests in start-ups, early-stage ventures, social ventures, SMEs, infrastructure or other sectors, areas which the GOVERNMENT AND REGULATORS CONSIDER AS SOCIALLY OR ECONOMICALLY DESIRABLE. Examples: Venture Capital Funds, Social Impact Funds, SME Funds, Infrastructure Funds, Special Situation Funds, Corporate Debt Market Development Fund.
2. Category II Alternative Investment Fund — prohibited from taking leverage or borrowing, except as prescribed by SEBI. Such Funds DO NOT FALL IN EITHER CATEGORY I OR CATEGORY III. Examples: Private Equity Funds, Debt Funds.
3. Category III Alternative Investment Fund — uses DIVERSE OR COMPLEX TRADING STRATEGIES. They may also employ leverage, including through investment in both listed and unlisted derivatives, to make SHORT-TERM PROFITS. Funds such as Hedge Funds... fall under Category III.
4. Specified Alternative Investment Fund — SEBI may specify regulations for such type of funds that do not fall under any 3 categories mentioned above.
Note how Category II is defined: not by what it does but by what it is not — it is the residual category for funds that fit neither I nor III.
The four permissible legal structures
- A "Company" formed under the Companies Act, 2013
- A "Trust" formed under a Trust Deed, duly registered under the provisions of the REGISTRATION ACT, 1908
- A "Limited Liability Partnership" incorporated under a Partnership Deed, which is filed with Registrar under the provisions of the Limited Liability Partnership Act, 2008
- A "Body Corporate" established under the laws of the Central or State Legislature
A sole proprietorship or an ordinary partnership firm is NOT a permissible structure — a point one of the chapter's own sample questions turns on.
17.1.2 What SEBI examines
SEBI decides on the eligibility and registration of an AIF by examination of the given documents and criteria for eligibility:
1. The Memorandum of Association / Trust Deed / Partnership Deed must permit it to carry on the activity of an AIF. REGISTRATION OF THESE LEGAL DOCUMENTS IS COMPULSORY for every applicant.
2. AIFs are PROHIBITED FROM MAKING AN INVITATION TO THE PUBLIC to subscribe to its units. Accordingly, such prohibition SHOULD BE INCLUDED in the memorandum and articles of association / or trust deed / or partnership deed of the applicant.
3. The Applicant, including its Sponsor and Manager, should be "FIT AND PROPER" as defined in SCHEDULE II of SEBI (Intermediaries) Regulations, 2008, which specifies four criteria:
- integrity, reputation and character
- no history of restraint orders and convictions
- financial competence based on net worth and solvency
- no history of being a WILFUL DEFAULTER
4. The certification requirement — this examination itself
At least ONE KEY PERSONNEL, amongst the associated persons functioning in the key investment team of the Manager of AIFs shall have the relevant certification as specified by SEBI:
- for Category I and/or Category II AIF Managers: either NISM-Series-XIX-C: Alternative Investment Fund Managers Certification Examination or NISM-Series-XIX-D: Category I and II Alternative Investment Fund Managers Certification Examination
- for Category III AIF Managers: either NISM-Series-XIX-C: Alternative Investment Fund Managers Certification Examination or NISM-Series-XIX-E: Category III Alternative Investment Fund Managers Certification Examination
In case of expiry of the validity of such certification, the personnel shall obtain FRESH CERTIFICATION. However, this provision is NOT APPLICABLE FOR AI-ONLY FUNDS.
And a second key personnel requirement: at least one key personnel with PROFESSIONAL QUALIFICATION in finance, accountancy, business management, commerce, economics, capital market or banking from a university or an institution recognised by the Central or any State Government or a foreign university OR A CFA CHARTER FROM CFA INSTITUTE... provided that BOTH the requirements... MAY BE FULFILLED BY THE SAME KEY PERSONNEL.
One certification, one qualification — and one person may satisfy both.
5. The Manager or Sponsor has the necessary INFRASTRUCTURE AND MANPOWER to discharge its activities.
6. The applicant has clearly described the investment objective, the targeted investors, proposed corpus, investment style or strategy and proposed tenure.
7. Whether the applicant or any entity established by the Sponsor or Manager has EARLIER BEEN REFUSED REGISTRATION by SEBI.
17.1.4 Conditions for registration
- The AIF shall abide by the provisions of the Act and the SEBI (AIF) Regulations, 2012
- The AIF shall NOT CARRY ON ANY OTHER ACTIVITY other than permitted activities
- The AIF shall FORTHWITH INFORM SEBI IN WRITING, if any information or particulars previously submitted to SEBI are found to be FALSE OR MISLEADING in any material particular or if there is any MATERIAL CHANGE in the information already submitted
- An AIF which has been granted registration under a particular category CANNOT CHANGE ITS CATEGORY subsequent to registration, EXCEPT WITH THE APPROVAL OF SEBI
17.1.5 In-principle approval
Filing of a Trust Deed and getting it registered under the Registration Act, 1908... may be time-consuming... In order to speed-up the Registration of Applicants... SEBI may grant an "IN-PRINCIPLE" APPROVAL to eligible applicants.
If SEBI is satisfied that the applicant meets the eligibility criteria... it may grant an in-principle approval... EVEN IF THE TRUST DEED OR PARTNERSHIP DEED, AS APPLICABLE, IS NOT REGISTERED under the applicable law.
However, after receiving the in-principle approval:
- The applicant must ensure the Trust Deed or Partnership Deed... is REGISTERED under the applicable law, WITHIN 6 MONTHS from the date of in-principle approval from SEBI.
- The applicant MAY START ACCEPTING COMMITMENTS from its investors, but SHALL NOT CALL/ACCEPT MONEY from such investors, UNTIL RECEIPT OF REGISTRATION CERTIFICATE from SEBI.
Commitments yes, money no — until the Registration Certificate arrives. And the deed must be registered within 6 months.
17.2 Sponsor and Manager commitment
- The Manager or Sponsor shall have a continuing interest in CATEGORY I AND II AIFs (in each scheme where there are multiple schemes in the fund) of NOT LESS THAN 2.5% OF THE CORPUS OR INR 5 CRORE WHICHEVER IS LOWER. The Sponsor or Manager of a CATEGORY III AIF shall have a continuing interest of NOT LESS THAN 5 PERCENT of the corpus of the fund OR INR 10 CRORE WHICHEVER IS LOWER.
- The commitment shall be in the form of INVESTMENT IN THE SCHEME of the fund and SHALL NOT BE THROUGH THE WAIVER OF MANAGEMENT FEES.
- The contribution of each EMPLOYEE OR DIRECTOR of the fund or employee or director of the investment manager in the corpus SHALL NOT BE LESS THAN INR 25 LAKH if they choose to participate as investors in the fund in individual capacity.
- The Manager or Sponsor shall DISCLOSE their investment interest in the AIF to the investors.
Note that the continuing interest applies in each scheme where there are multiple schemes in the fund — not merely at fund level.
17.3 Open-ended and close-ended structures
In an OPEN-ENDED fund structure:
- Investors contribute their capital UPON ADMISSION OR SUBSCRIPTION to the Fund.
- Investors may make ADDITIONAL capital contributions from time-to-time, if required.
- Redemption of capital from the fund is permitted at pre-defined regular intervals, being QUARTERLY, HALF-YEARLY OR YEARLY.
In a CLOSE-ENDED fund structure:
- Investors make CAPITAL COMMITMENTS, which are called by the Investment Manager by making "Capital Calls"... over a pre-defined period known as "COMMITMENT PERIOD".
- The Commitment Period is usually THE FIRST THREE YEARS of the Fund Tenure.
- REDEMPTION OF CAPITAL IS NOT PERMITTED in a close-ended fund structure, prior to winding-up. Investors would need to pay an EXIT LOAD for exiting from the fund, after the lock-in period specified in the PPM.
Who may be which
Category I and II AIFs need to COMPULSORILY be formed as CLOSE-ENDED funds because such investments are PRIMARILY ILLIQUID... Investors are meant to realise cash returns on their fund interests only when realisation events occur through the sale of the underlying portfolio companies.
Schemes of all Category III Alternative Investment Funds are EITHER OPEN-ENDED OR CLOSE-ENDED, as structured by the Sponsor or Investment Manager, AT THE TIME OF REGISTRATION.
17.3.3 Listing of close-ended schemes
Units of a scheme launched by a CLOSE-ENDED AIF are eligible for listing on a recognized stock exchange. The scheme should have a MINIMUM TRADABLE LOT OF INR 1 CRORE and listing shall be permitted ONLY AFTER FINAL CLOSE of the fund or scheme. UNITS OF ANGEL FUNDS SHALL NOT BE LISTED on any recognised stock exchange. LISTING... IS VOLUNTARY.
The four-step process:
- An AIF must make an APPLICATION TO A RECOGNIZED STOCK EXCHANGE for listing... submit the required documentation and pay the designated fees based on the size of the Fund/Scheme.
- Based on the documentation, the recognized stock exchange grants an IN-PRINCIPLE APPROVAL.
- The AIF seeks APPROVAL FROM SEBI, for listing of units of its close-ended scheme.
- After receiving SEBI approval... the recognized stock exchange can grant the FINAL APPROVAL and list the units.
Exchange in-principle approval first, then SEBI approval, then exchange final approval.
Benefits of Listing: provide investors with an EASY EXIT OPPORTUNITY, subject to KYC; enable PRICE DISCOVERY in a demand-supply mechanism; enable investors to VIEW THE NAV of the fund on a timely basis; ensure LIQUIDITY in the AIF industry.
Think of it like this
Category II is defined by exclusion
Most categories in law are defined by what belongs in them. Category II is defined by what does not.
Category I is the "desirable" box — invests in start-ups, early-stage ventures, social ventures, SMEs, infrastructure or other sectors, areas which the government and regulators consider as socially or economically desirable. Venture capital, social impact, SME, infrastructure, special situation and corporate debt market development funds.
Category III is the "complex" box — uses diverse or complex trading strategies... may also employ leverage, including through investment in both listed and unlisted derivatives, to make short-term profits. Hedge funds.
Category II is everything left over: such Funds DO NOT FALL IN EITHER CATEGORY I OR CATEGORY III of AIFs, and are prohibited from taking leverage or borrowing, except as prescribed by SEBI. Private equity and debt funds live here — not because a rule welcomed them in, but because no other box fitted.
That residual character explains a lot of the regulation. Category I gets concessions because policy favours it. Category III gets leverage because its strategies require it. Category II gets neither the concessions nor the leverage — it simply gets on with buying unlisted companies.
And when a fund fits nowhere at all, a fourth door exists: Specified Alternative Investment Fund — SEBI may specify regulations for such type of funds that do not fall under any 3 categories mentioned above.
The certification you are studying for is a registration condition
There is something unusual about this chapter: it describes the requirement that produced the examination you are sitting.
At least one key personnel, amongst the associated persons functioning in the key investment team of the Manager of AIFs shall have the relevant certification as specified by SEBI — for Category I and II managers, either NISM-Series-XIX-C: Alternative Investment Fund Managers Certification Examination or NISM-Series-XIX-D, and for Category III managers, either NISM-Series-XIX-C... or NISM-Series-XIX-E.
Notice the design. XIX-C covers both, which is why this workbook spans venture capital, private equity, hedge fund strategies, derivatives leverage and everything in between. XIX-D and XIX-E are the narrower routes.
Two more details are examinable. First, it does not lapse quietly: in case of expiry of the validity of such certification, the personnel shall obtain fresh certification to ensure compliance with certification norms. Second, there is one carve-out: this provision is not applicable for AI-only Funds — where every investor is accredited, SEBI relaxes several investor-protection requirements, and this is one of them.
And the certification requirement sits beside a qualification requirement — at least one key personnel with professional qualification in finance, accountancy, business management, commerce, economics, capital market or banking... or a CFA charter — with the sensible proviso that both the requirements... may be fulfilled by the same key personnel.
Commitments yes, money no
Registering a trust deed under the Registration Act, 1908 takes time. Meanwhile investors are interested and a fund manager is losing momentum.
SEBI's answer is the in-principle approval: if SEBI is satisfied that the applicant meets the eligibility criteria... it may grant an in-principle approval to the applicant for the AIF, even if the Trust Deed or Partnership Deed, as applicable, is not registered under the applicable law.
But it comes with a precise boundary that candidates routinely blur:
The applicant MAY START ACCEPTING COMMITMENTS from its investors, but SHALL NOT CALL/ACCEPT MONEY from such investors, UNTIL RECEIPT OF REGISTRATION CERTIFICATE FROM SEBI.
A commitment is a promise; money is money. The manager may collect promises on in-principle approval, but cannot draw down a rupee until the certificate arrives. And the clock runs: the applicant must ensure the Trust Deed or Partnership Deed... is registered under the applicable law, WITHIN 6 MONTHS from the date of in-principle approval.
The fund-raising table in the chapter maps it exactly — Step 3: Receive SEBI In-principle Approval... Step 4: After receiving in-principle approval, the fund can approach investors to raise capital commitments, BUT NOT RAISE MONEY... Step 5: Obtain SEBI Registration Certificate in Form B. Only then does Step 6, First Close, become possible.
Skin in the game, and it must be cash in each scheme
A manager could, in principle, claim to have skin in the game by waiving his own fee. SEBI closes that door explicitly.
The commitment shall be in the form of INVESTMENT IN THE SCHEME of the fund and shall NOT be through the WAIVER OF MANAGEMENT FEES.
Waiving a fee you were going to receive is not risking capital you already own. It costs the manager an opportunity, not an asset, and it disappears the moment the fund performs badly enough that no fee would have been earned anyway.
The amounts differ by category and, in both cases, take the lower of two figures:
Category I and II: not less than 2.5% of the corpus or INR 5 crore, whichever is LOWER. Category III: not less than 5 percent of the corpus of the fund or INR 10 crore, whichever is LOWER.
Two further points that catch people. The commitment applies in each scheme where there are multiple schemes in the fund — not once at fund level. And a separate floor applies to insiders investing personally: the contribution of each employee or director of the fund or employee or director of the investment manager in the corpus shall not be less than INR 25 LAKH — a fifth of the ordinary INR 1 crore minimum, recognising that these are people with information but not necessarily large means.
Finally, none of it is private: the Manager or Sponsor shall disclose their investment interest in the AIF to the investors.
Two lanes for capital, and no bridge between them
A close-ended AIF and an open-ended one handle money in opposite ways, and the difference decides almost everything else about the fund.
Open-ended: investors contribute their capital upon admission or subscription to the Fund... may make additional capital contributions from time-to-time... Redemption of capital from the fund is permitted at pre-defined regular intervals, being quarterly, half-yearly or yearly. Money in at the start, out on a schedule.
Close-ended: investors make capital commitments, which are called by the Investment Manager by making "Capital Calls"... over a pre-defined period known as "Commitment Period" — usually the first three years of the Fund Tenure — and redemption of capital is NOT permitted... prior to winding-up of the Fund.
Now the allocation, which is not a choice for two categories: Category I and II AIFs need to compulsorily be formed as close-ended funds because such investments are primarily illiquid, while schemes of all Category III Alternative Investment Funds are either open-ended or close-ended, as structured by the Sponsor or Investment Manager, at the time of registration.
The logic is entirely about what the fund owns. You cannot promise quarterly redemption to investors while holding a seven-year stake in an unlisted company. Liquidity out must match liquidity in — which is also why the only route to early exit in a close-ended fund is an exit load... after the lock-in period specified in the PPM, or listing.
Listing: three approvals, one crore lots, and nothing for angels
A close-ended AIF is a locked box for years. Listing offers a keyhole.
Units of a scheme launched by a close-ended AIF are ELIGIBLE for listing on a recognized stock exchange. But look at the conditions, each of which limits who benefits.
The scheme should have a MINIMUM TRADABLE LOT OF INR 1 CRORE. That is not a retail market — the lot size deliberately keeps the same sophisticated-investor threshold the whole framework rests on.
Listing shall be permitted ONLY AFTER FINAL CLOSE of the fund or scheme. No trading while the fund is still raising money.
Units of angel funds shall NOT be listed on any recognised stock exchange. Angel investments are the earliest and least valuable to price — a market in them would mislead more than it informs.
Listing... is VOLUNTARY. Nobody is obliged.
And the process runs through three approvals in a strict order: the recognized stock exchange grants an in-principle approval, then the AIF seeks approval from SEBI, then the recognized stock exchange can grant the final approval and list the units.
The benefits the workbook claims are worth remembering as a set: an easy exit opportunity, subject to KYC; price discovery in a demand-supply mechanism; NAV visibility on a timely basis; and liquidity in the AIF industry.
