The Three AIF Categories — I, II and III
SEBI's AIF Regulations place every Alternative Investment Fund in one of three categories. This lesson explains which funds belong in Category I, II and III, and how the category decides a fund's structure and its freedom to borrow or use leverage.
Why the category matters
Every AIF is registered in one of three categories. The category is not a quality rating. It tells the reader what kind of investing the fund does, and it decides which rules apply to it: whether it must be close-ended, whether it may borrow, and, as a later lesson shows, how its income is taxed.
Category I
Category I covers venture capital funds, angel funds, SME funds, social impact funds, infrastructure funds and special situation funds. Social impact funds were formerly called social venture funds.
The common thread is investment in early-stage businesses, smaller enterprises, social ventures, infrastructure or stressed assets. These are high-risk areas: investee companies may fail, and units of a close-ended fund cannot be redeemed at will.
Category II
Category II is defined by what it is not. It is the residual group: any AIF that falls in neither Category I nor Category III. Private equity funds, private credit (debt) funds and real estate funds are common examples.
A fund does not need to match a named sub-type to be in Category II. If it is not a Category I fund and does not use the trading strategies and leverage of Category III, this is where it sits.
Category III
Category III funds are defined as funds that use diverse or complex trading strategies and may use leverage. Hedge funds and long-short funds are examples.
Leverage means taking exposure larger than the fund's own capital. It magnifies gains and losses alike, so a leveraged fund can lose capital faster than an unleveraged one.
Structure and borrowing
Categories I and II must be close-ended: the fund has a fixed term and does not redeem units on request. They may not borrow, except for temporary funding and day-to-day operational needs and within limits. Borrowed money cannot be a lasting part of their strategy.
Category III is treated differently. It may be open-ended or close-ended, and it may use leverage, subject to a cap set by SEBI. In every category investors face illiquidity, valuation uncertainty and possible loss of capital.
Rules at a glance
Sorting four funds
Take four invented funds. The first backs young technology companies in return for shares: a venture capital fund, so Category I. The second invests in stressed assets: a special situation fund, also Category I.
The third lends to established unlisted companies: a private credit fund, which is neither Category I nor Category III, so Category II. The fourth buys some listed shares and takes short positions in others, using leverage: a long-short fund, so Category III.
The category tells the reader the type of investing and the rules that follow. It does not say which fund will do well. All four can lose capital.
Key points
- Category I: venture capital, angel, SME, social impact, infrastructure and special situation funds.
- Category II: funds that are neither Category I nor Category III, such as private equity, private credit and real estate funds.
- Category III: funds using diverse or complex trading strategies, which may use leverage; hedge funds and long-short funds are examples.
- Categories I and II are close-ended and may borrow only for temporary needs, within limits.
- Category III may be open-ended or close-ended; leverage can magnify losses.
Common misunderstandings
- The category number is not a risk or quality ranking: it classifies the kind of investing and decides which rules apply.
- Category II is not a list of named fund types: it is the residual category for funds in neither Category I nor Category III.
- Category I and II funds cannot run on borrowed money: they may borrow only for temporary needs, within limits.
- Social venture funds have not disappeared: they are now called social impact funds and remain in Category I.
Questions people ask
Which category is a venture capital fund?
Category I, the same category as angel funds, SME funds, social impact funds, infrastructure funds and special situation funds.
How is Category II defined?
As a residual category: it covers AIFs that fall in neither Category I nor Category III. Private equity, private credit and real estate funds are common examples.
Which category may use leverage?
Category III, which uses diverse or complex trading strategies. Category I and II funds may not borrow except to meet temporary needs.
