Concepts and Terms Related to Mutual Funds
This sub‑topic covers the fundamental concepts and terminology used in mutual funds. Understanding these terms is essential for answering definition‑based and calculation questions in the NISM Series X‑A exam. The content links each term to its practical implication for investors and the regulatory expectations of SEBI.
Learning Objectives
- 1Define mutual fund, NAV, AUM and related key terms.
- 2Identify different scheme categories and their risk‑return profile.
- 3Calculate NAV and expense ratio using the official formulas.
- 4Explain the impact of SIP, load structures and regulatory disclosures on investor decisions.
What is a Mutual Fund?
A mutual fund is a pooled investment vehicle managed by a registered Asset Management Company (AMC) on behalf of investors. The AMC collects money from many small investors, creates a diversified portfolio of securities, and issues units that represent a proportionate share of the fund’s assets.
Mutual funds are open‑ended in most cases, meaning investors can buy or redeem units at any business day at the prevailing Net Asset Value (NAV). This liquidity, combined with professional management, makes mutual funds a popular choice for retail investors in India.
For the NISM exam, you must know the legal definition, the role of the trustee, and the distinction between open‑ended and close‑ended schemes, as questions often test regulatory knowledge.
- Open‑ended: continuous issue/redemption.
- Close‑ended: fixed tenure, tradable on stock exchanges.
Key Terminology
Net Asset Value (NAV) is the per‑unit price of a mutual fund, calculated at the end of each trading day. It reflects the market value of the fund’s assets minus liabilities, divided by the number of units outstanding.
Assets Under Management (AUM) denotes the total market value of assets that the AMC manages across all its schemes. A higher AUM often indicates scale, but it does not guarantee better performance.
Expense Ratio is the annual cost expressed as a percentage of the fund’s average net assets. It includes management fees, custodian charges, and other operational expenses, and directly reduces the investor’s returns.
Load refers to a commission charged on purchase (entry load) or redemption (exit load) of units. SEBI has capped entry loads to zero for most schemes, but exit loads are still common and affect the effective return.
Other important terms include Scheme Category (equity, debt, hybrid, liquid, ELSS), Dividend vs Growth option, Systematic Investment Plan (SIP), and Lock‑in period for ELSS funds.
Many candidates confuse NAV with the market price of a unit. NAV is calculated by the fund house and is the price at which units are bought or sold, whereas market price applies only to close‑ended funds listed on an exchange.
Where:
Total Assets= Market value of all securities and cash held by the fund (in rupees)Liabilities= Fund's obligations such as expenses payable (in rupees)Units Outstanding= Total number of mutual fund units issued to investorsWorked Example
Given Total Assets = 1,00,00,000, Liabilities = 5,00,000, Units Outstanding = 9,50,000: Step 1: NAV = (1,00,00,000 - 5,00,000) / 9,50,000 Step 2: NAV = 99,50,000 / 9,50,000 = 10.4737 rupees per unit Verification: (1,00,00,000 - 5,00,000) / 9,50,000 = 10.4737.
Types of Mutual Fund Schemes
Mutual fund schemes are classified primarily by the asset class they invest in and the investment horizon they target. The major categories are Equity, Debt, Hybrid, Liquid, and Equity‑Linked Savings Scheme (ELSS).
Equity funds invest more than 65% of their net assets in equities and are suitable for long‑term wealth creation, but they carry higher market risk. Debt funds invest at least 80% in fixed‑income securities, offering relatively stable returns and lower volatility.
Hybrid funds blend equity and debt to balance risk and return, while liquid funds invest in money‑market instruments with maturities up to 91 days, providing high liquidity and modest returns. ELSS funds provide tax benefits under Section 80C and have a mandatory 3‑year lock‑in period.
Understanding these categories helps you answer scenario‑based questions where the exam asks you to recommend a scheme based on an investor’s risk appetite and time horizon.
Comparison of Major Mutual Fund Scheme Types
| Scheme Type | Typical Investment Horizon | Risk Level | Typical Return Range (p.a.) |
|---|---|---|---|
| Equity | 5 years or more | High | 10% – 15% |
| Debt | 2 – 5 years | Low to Moderate | 6% – 9% |
| Hybrid | 3 – 7 years | Moderate | 8% – 12% |
| Liquid | Up to 91 days | Very Low | 3% – 5% |
| ELSS | 3 years (lock‑in) | High | 10% – 15% |
Fund Structures and Unit Options
Open‑ended schemes issue and redeem units at NAV, while close‑ended schemes have a fixed number of units that trade on an exchange at market price. Investors must understand this distinction because redemption timing and pricing differ.
Mutual funds offer two unit options: Growth (units increase in value, no dividend distribution) and Dividend (periodic payout of income). The dividend option reduces the NAV by the amount of dividend paid, which can affect total return calculations.
Load structures vary: SEBI has eliminated entry loads for most schemes, but exit loads (typically 0.5% – 1% if redeemed within a specified period) remain. Knowing the exact load schedule is crucial for calculating net returns in exam questions.
Candidates often add dividend income to the final NAV without reducing the NAV for the dividend payout. Remember: total return = (NAV at redemption + dividends received) – (NAV at purchase).
Expense Ratio and Other Charges
The expense ratio represents the annual cost of managing a mutual fund, expressed as a percentage of average net assets. It includes the management fee, custodian fee, audit fee, and other operational expenses.
A higher expense ratio erodes investor returns, especially over long horizons. For example, a 2% expense ratio reduces a 12% gross return to roughly 10% net return, assuming other factors remain constant.
Other charges to be aware of are the transaction cost (brokerage for buying/selling securities) and the exit load. SEBI mandates that all charges be disclosed in the Scheme Information Document (SID) and Key Information Memorandum (KIM).
Where:
Total Expenses= Sum of management, custodian, audit and other operational fees in rupees for the yearAverage Net Assets= Average market value of the fund’s assets during the year in rupeesWorked Example
Given Total Expenses = 2,00,000 and Average Net Assets = 1,00,00,000: Step 1: ER = (2,00,000 / 1,00,00,000) × 100 Step 2: ER = 0.002 × 100 = 0.20% Verification: (2,00,000 / 1,00,00,000) × 100 = 0.20%.
Performance Measures
Exam questions often ask you to differentiate between total return, CAGR, and risk‑adjusted metrics. Total return includes price appreciation plus any dividends or capital gains distributed.
CAGR (Compound Annual Growth Rate) smooths out volatility and is calculated as \(\left(\frac{V_f}{V_i}\right)^{1/n} - 1\). It is preferred over simple average return because it accounts for compounding.
Risk‑adjusted measures such as the Sharpe Ratio (excess return per unit of standard deviation) and Beta (relative volatility to the benchmark) are useful for comparing funds with different risk profiles. While exact formulas are not required for the Level‑1 exam, you should know their definitions and interpretation.

Systematic Investment Plan (SIP) and Systematic Withdrawal Plan (SWP)
A SIP allows investors to invest a fixed amount at regular intervals (monthly, quarterly) in a mutual fund. SIPs promote rupee‑cost averaging, reducing the impact of market volatility.
The future value of a SIP can be estimated using the formula \(FV = P \times \frac{(1+r)^n - 1}{r} \times (1+r)\), where \(P\) is the periodic investment, \(r\) is the periodic rate of return, and \(n\) is the total number of periods.
SWP works in reverse, allowing periodic withdrawals while the remaining corpus continues to earn returns. Understanding both concepts helps you answer scenario questions on cash‑flow planning.
Where:
P= Periodic investment amount (rupees per period)r= Periodic rate of return (decimal, e.g., 0.01 for 1% per month)n= Total number of periods (e.g., months)Worked Example
Invest ₹1,000 monthly for 3 years at an annual return of 12% (monthly r = 0.12/12 = 0.01), n = 36: Step 1: FV = 1000 × ((1+0.01)^{36} - 1) / 0.01 × (1+0.01) Step 2: (1.01)^{36} ≈ 1.4308 → numerator = 1.4308 - 1 = 0.4308 Step 3: FV = 1000 × (0.4308 / 0.01) × 1.01 = 1000 × 43.08 × 1.01 ≈ 43,511 rupees Verification: 1000 × ((1.01)^{36} - 1) / 0.01 × 1.01 ≈ 43,511.
Regulatory Framework and Disclosure Requirements
SEBI (Securities and Exchange Board of India) regulates mutual funds under the SEBI (Mutual Funds) Regulations, 1996, as amended. Every scheme must publish a Scheme Information Document (SID) and a Key Information Memorandum (KIM) that disclose investment objectives, risk factors, expense ratio, and past performance.
All investors must complete KYC (Know Your Customer) verification before purchasing units. The AMC must appoint a trustee (usually a bank) to safeguard investor interests and ensure compliance with SEBI norms.
For the exam, remember the mandatory disclosures: expense ratio, exit load schedule, minimum investment amount, and lock‑in period (if any). Questions may present a scenario and ask which document contains a specific piece of information.
⭐Exam Takeaways
- Mutual fund NAV = (Total Assets – Liabilities) ÷ Units Outstanding; it is the price for buying/redeeming units in open‑ended schemes.
- Expense Ratio = (Total Expenses ÷ Average Net Assets) × 100; a lower ratio directly improves net returns.
- Scheme categories – Equity (high risk, high return), Debt (low‑moderate risk), Hybrid (balanced), Liquid (high liquidity), ELSS (tax‑saving with 3‑year lock‑in).
- SIP future value formula: FV = P × ((1+r)^n – 1)/r × (1+r); use monthly rate for monthly SIP calculations.
- SEBI mandates KYC, SID, KIM, and trustee oversight; exit loads apply only if redemption occurs within the prescribed period.
