Internal funds are a type of mutual fund where units can be bought or sold on a predetermined period only. Here we will discuss interval mutual funds, the features, and the benefits of investing in these funds.  

Let’s begin by understanding: what are interval funds?

What are interval funds?

Interval funds are different from common open-ended mutual funds. These funds can invest in debt and equities both. But these have restricted liquidity and can be bought and sold at a predetermined time. Investors usually use interval funds to park their capital in debt funds. These funds combine the features of close-ended and open-ended funds. Investors can trade the units on the stock exchange or redeem them during a pre-decided period at NAV price.

Features of interval mutual funds 

Here are the critical features of an interval fund. 

  • Because of their specialised design, these funds are best suited for short-term investment.
  • These funds are highly illiquid. Investors can buy or sell the units only at a specified time.
  • Interval funds typically invest in debt securities. Hence, these funds rank low in the risk spectrum.
  • Investors need to be careful about the expense ratio. Usually, interval funds charge more than other mutual funds.
  • Taxation depends on the quantum of investment in debt or equities.     

How do interval funds work?

Interval funds are a combination of open-ended and closed-ended funds. These funds allow investors to buy or sell units only during a particular window. Since they are rare, only a few funds are available in this category. During the predetermined window, investors can buy or sell their units at a prevailing NAV. 

The asset management company determines the interval when investors can redeem their units. Hence, it allows fund managers to create a solid investment strategy without worrying about redemption by investors. 

Interval funds primarily invest in debt instruments to earn low-risk returns. 

Who should invest in interval mutual funds?

Each mutual fund is designed with a specific focus to cater to the specialised investment needs of investors. Similarly, interval funds also serve the particular needs of investors. These funds invest in illiquid assets like commercial properties, forestry tracts, business loans, and others, which are suitable for investors looking to invest in unconventional assets. These funds are also appropriate for short-term investors with a low-to-moderate risk profile.

Benefits of interval mutual funds 

  • The returns earned by interval mutual funds are often more than open-ended mutual funds.
  • It allows retail investors to gain exposure to unconventional assets.
  • Investors can invest in institutional-grade alternative investments with low minimums.
  • The asset management company makes periodic offers to investors to repurchase shares at NAV.

Things to consider as an investor  

Many investors compare interval funds with closed-ended funds. But the closed-ended funds don’t allow investors to withdraw for a long time. But these funds allow investors to buy and sell during a predetermined window. It also shares characteristics with fixed maturity plans (FMP). The following are the points that investors should remember while investing.

Risk and returns 

Interval funds primarily invest in highly illiquid assets and are available for redemption only during a specific redemption window. Hence, you will not be able to use your fund during an emergency. You can’t also sell your units in the secondary market. 

However, interval funds have earned more returns than open-ended funds. Investing in alternative types of assets also helps increase interval fund yields. Typically, interval funds have generated an average return of 6-8 percent for five years. 

Investing according to your investment plan

Interval funds are ideal for parking your investment for the short term. While these funds can invest in debt and equities, most schemes will invest in debt instruments. Hence, these are suitable for low-risk investors and offer low returns. 

Buying is easy but expensive 

These funds usually offer to sell their units at the prevailing NAV value regularly, which can increase the cost of investing. Sometimes these units are restricted to accredited investors. But often, these units are also available to retail investors to buy.

Restricted selling opportunities 

Investors of interval funds can’t sell their units at any time. These funds allow predetermined windows when buying and selling of units are possible. Also, you may not be allowed to sell all your units simultaneously.

High yields

Because of the illiquid structure, fund managers can invest without the pressure of redemption. It allows them to work on solid investment strategies to earn higher returns. The ability to invest in alternative assets also improves the yields of interval funds.

Costs are high too

On the flip side, interval funds are more expensive than open-ended funds. The expense ratio of these funds can be higher than 5.75% and include sales, management, servicing, and operating charges.

Tax implication 

In the case of mutual funds, the taxation rule depends on the ratio of fund allocation. The same rule applies to interval funds. It depends on whether the fund primarily invests in equities or debt. If fund allocation in equities is more than 65 percent, then it will be treated as an equity fund during taxation. Similarly, if the interval fund invests 65 percent or more in debt instruments, it will be treated as a debt fund.
