What Is a Scheme Information Document (SID)?
Every mutual fund scheme in India has three different documents describing it — a factsheet, a Key Information Memorandum, and a Scheme Information Document — and they are not interchangeable. Only one of them is the actual legal contract. This guide explains what each document is for and where to find the details that are legally binding.
The Scheme Information Document, almost always shortened to SID, is the formal offer document that an Asset Management Company (AMC) files for every scheme it launches. It is the closest thing a mutual fund has to a legal charter: it sets out the scheme's investment objective, the asset allocation pattern it must follow, the types of instruments it can and cannot invest in, the risk factors specific to that scheme, load structure, valuation policy, and the rights of unit holders. If a dispute ever arises about what a scheme was permitted to do, the SID — not the factsheet, not the marketing brochure — is the document that governs the answer.
Why the SID Exists
Mutual funds in India are regulated by SEBI, and every scheme must be registered before it can accept money from investors. The SID is the document AMCs are required to prepare and keep updated as part of that regulatory framework — it is reviewed and made available so that investors have full disclosure of what a scheme is, not just a marketing summary of what it hopes to achieve. Because the SID is a compliance document rather than a promotional one, it tends to be long, formally worded, and organized around disclosure requirements rather than readability. That is precisely why most investors never open one, and why summarized versions exist alongside it.
SID vs KIM: Full Document vs Summary
The Key Information Memorandum (KIM)is a condensed version of the SID, designed to be short enough that an investor can realistically read it before investing. It typically accompanies the application form and covers the essentials — investment objective, asset allocation, risk factors, plans and options, minimum investment amount, load structure, and the fund manager's name — in a few pages instead of dozens. Historically, the KIM was the document physically attached to a paper application form; today it usually appears as a short PDF alongside the online transaction flow.
The relationship between the two is explicitly hierarchical: the KIM is a summary, and it says so on its own cover page, directing investors to the full SID for complete details. If anything in the KIM appears to conflict with the SID, or if a scenario the KIM does not cover comes up, the SID is the authoritative source. In practice this means the KIM is useful for a quick first read, but any decision that hinges on precise wording — exact exit load conditions, the fine print on asset allocation limits, or how a scheme defines a particular risk — should be checked against the SID itself, not the KIM.
Where the Monthly Factsheet Fits In
The monthly factsheet is a different document entirely, and it is not a legal or regulatory filing in the way the SID and KIM are. An AMC publishes a factsheet every month purely as an investor-communication tool — it reports the scheme's current portfolio holdings, AUM, NAV, expense ratio, sector allocation, and trailing returns as of that month-end. None of that is a binding commitment; it is a snapshot of what the fund currently looks like, and it will look different next month as the fund manager buys and sells within the boundaries the SID allows. For a full section-by-section breakdown of what a factsheet contains and how to read it, see our guide on how to read a mutual fund factsheet.
A simple way to keep the three straight: the SID is the rulebook that defines what a scheme is legally allowed to do, the KIM is the short-form summary of that rulebook meant for a pre-investment read, and the factsheet is a monthly progress report showing what the scheme is actually doing within those rules right now. Only the SID carries the full, legally binding detail — the other two exist to make that detail more approachable, not to replace it.
What You Will Actually Find Inside a SID
A typical SID is organized into standardized sections covering the scheme's highlights, due diligence certification, investment objective and strategy, permitted and restricted investments, risk factors (both general to mutual funds and specific to the scheme), the scheme's asset allocation pattern with permissible ranges by instrument type, fees and expenses including the maximum expense ratio the scheme can charge, load structure, and the rights of unit holders including procedures for redemption and winding up. Because it is a compliance document, it is periodically updated through addenda whenever a material change occurs — a change in fund manager, a shift in asset allocation limits, or a revision to exit load, for instance — so the version available on the AMC's website is usually the current one, addenda included.
None of this is meant to suggest an investor needs to read a full SID before every purchase. For most day-to-day decisions, the KIM and the factsheet cover what is practically useful. But when a question genuinely turns on the fine print — what a scheme is contractually allowed to invest in, or the exact conditions attached to an exit load — the SID, published on the AMC's own website and on SEBI-mandated disclosure platforms, is the only document that settles it. If you want to see how a scheme's current holdings translate into practice — the actual stocks and their weights rather than the permitted ranges described in the SID — you can see a live fund page on WhoHolds for a real example.
This guide is meant to help you understand what these documents are and where to find them — it is not a recommendation to invest in any particular scheme. Reading the SID or KIM for a scheme you are considering, and consulting a certified financial advisor where needed, remains the responsible way to act on this information.
Frequently Asked Questions
- Is the SID legally binding?
- Yes. The Scheme Information Document is the formal offer document filed as part of a scheme's registration, and it governs what the scheme is permitted to invest in and how it must operate. The KIM and factsheet are both derived from it, not the other way around.
- Do I need to read the full SID before investing?
- Not for most everyday decisions — the Key Information Memorandum summarizes the essentials in a few pages. The full SID matters most when a specific question depends on exact wording, such as precise exit load conditions or asset allocation limits.
- Where can I find a scheme's SID?
- AMCs are required to publish the current SID, including any addenda, on their own websites, alongside the KIM and factsheet for each scheme.
- Why does the SID get updated through addenda instead of being reissued?
- Addenda let an AMC disclose a material change — such as a new fund manager or a revised load structure — as soon as it happens, without waiting to reprint the entire document. The addenda are read together with the base SID as a single current document.
