# Section 31 — Shelf Prospectus
## Why It Exists
If a company makes multiple issues of securities frequently in the same year, filing a fresh prospectus every time is costly and cumbersome. The shelf prospectus solves this — file once, issue multiple times.
## Definition
A "shelf prospectus" means a prospectus in respect of which the securities or class of securities included therein are issued for subscription in one or more issues over a certain period without the issue of a further prospectus.
Literal meaning: A prospectus that has a "shelf life" — kept on the shelf, used multiple times.
## Key Tool: Information Memorandum
During the shelf life, a company supplements the shelf prospectus by an "Information Memorandum" containing key updates/changes between issues — no fresh prospectus needed.
## Provisions of Section 31
### 1. Filing with Registrar
- Eligibility: Any class or classes of companies as SEBI provides by regulations.
- Such company may file a shelf prospectus with the Registrar.
### 2. Validity Period
Filing stages:
- (i) At first offer: Indicate validity period — not exceeding one year from the date of opening of the first offer.
- (ii) Second/subsequent offers within validity period: No further prospectus is required.
### 3. Information Memorandum — Mandatory Filing
Before each subsequent offer, file an Information Memorandum containing all material facts on:
- (i) New charges created
- (ii) Changes in financial position between the previous offer and the succeeding offer
- (iii) Other prescribed changes
File within prescribed time prior to the issue of a second or subsequent offer.
### 4. Intimation to Existing Applicants
If the company has received applications + advance payments before such change:
- Company must intimate the changes to applicants.
- If applicants wish to withdraw, company must refund all monies received as subscription within 15 days.
### 5. Deemed Prospectus
When Information Memorandum is filed with the shelf prospectus, together they shall be deemed to be a prospectus.
