Introduction

Dematerialization of securities has become a key compliance requirement for companies in India. To ensure that securities are held and transferred electronically and that company records accurately match depository records, the Ministry of Corporate Affairs (MCA) introduced Rules 9A and 9B under the Companies (Prospectus and Allotment of Securities) Rules, 2014.

One of the most significant compliances arising from these provisions is the filing of Form PAS-6, commonly known as the Reconciliation of Share Capital Audit Report. This report enables regulators to verify the accuracy of a company's share capital records and monitor compliance with dematerialization requirements.

Understanding Dematerialization of Securities

Traditionally, shares were issued and transferred through physical share certificates. However, physical securities often led to issues such as loss of certificates, forgery, duplication, and disputes regarding ownership.

To address these challenges, securities are now encouraged to be held in electronic form through depositories. The process of converting physical securities into electronic form is known as dematerialization or "demat."

In India, securities are maintained electronically through two recognized depositories:

  1. National Securities Depository Limited (NSDL)

  2. Central Depository Services (India) Limited (CDSL)

Dematerialization improves transparency, enhances security, facilitates faster transfers, and reduces administrative burdens on companies and shareholders.

What is ISIN?

Before any security can be held in dematerialized form, it must be assigned a unique identification number known as the International Securities Identification Number (ISIN).

An ISIN is a unique code for a particular class of securities and helps depositories, companies, investors, and regulators identify securities accurately.

Each class of shares receives a separate ISIN. (Equity Shares, Preference Shares)

A company cannot facilitate dematerialization of its securities without obtaining an ISIN from the depository system through a Registrar and Share Transfer Agent (RTA).

Rule 9A – Applicability to Unlisted Public Companies

Rule 9A of the Companies (Prospectus and Allotment of Securities) Rules, 2014 mandates that every unlisted public company shall issue and facilitate transfer of its securities only in dematerialized form.

Under Rule 9A, an unlisted public company is required to:

  1. Obtain ISIN for its securities.
  2. Establish connectivity with a depository.
  3. Facilitate dematerialization of securities held by shareholders.
  4. Ensure that promoters, directors, and key managerial personnel hold securities in demat form before undertaking specified corporate actions.
  5. File periodic reconciliation reports through Form PAS-6.

Certain categories such as Government Companies, Nidhi Companies, and Wholly Owned Subsidiaries are exempt from the applicability of Rule 9A.

Rule 9B – Applicability to Private Companies

To further expand the scope of dematerialization, MCA introduced Rule 9B, which extends similar requirements to certain private companies.

Rule 9B applies primarily to private companies that are not classified as Small Companies under the Companies Act, 2013.

These companies are required to:

  1. Obtain ISIN for their securities.
  2. Facilitate dematerialization of securities.
  3. Comply with applicable provisions relating to depositories.
  4. File PAS-6 as required under the applicable provisions.

Small Companies continue to enjoy exemption from these requirements.

Reconciliation of Share Capital

Once securities are dematerialized, a company's shareholding may exist in three forms:

  1. Shares held in demat form with NSDL.
  2. Shares held in demat form with CDSL.
  3. Shares held in physical form.

The company must periodically verify whether the aggregate of these holdings matches its issued share capital.

This verification process is known as Reconciliation of Share Capital.

For example:

Issued Share Capital: 1,00,000 Shares

  1. Shares in NSDL: 40,000
  2. Shares in CDSL: 50,000
  3. Physical Shares: 10,000

Total: 1,00,000 Shares

Any mismatch between company records and depository records must be identified and explained.

Form PAS-6: Reconciliation of Share Capital Audit Report

Form PAS-6 is a half-yearly compliance filing submitted to the Registrar of Companies (ROC).

The purpose of PAS-6 is to provide a certified reconciliation of the company's share capital with records maintained by depositories.

The form contains details relating to:

  1. Company's particulars.
  2. ISIN of securities.
  3. Issued and paid-up capital.
  4. Securities held with NSDL.
  5. Securities held with CDSL.
  6. Physical holdings.
  7. Changes in share capital during the reporting period.
  8. Dematerialization requests and their status.
  9. Any discrepancies identified during reconciliation.

Certification Requirement

PAS-6 is an audit-based certification.

The report must be certified by Company Secretary (CS), or Chartered Accountant (CA)

The professional certifies that the company's records have been verified and reconciled with depository records.

Half-Yearly Filing Requirement

PAS-6 must be filed every six months.

The filing periods are:

First Half-Year

1 April to 30 September

Due Date within 60 days from 30 September.

Second Half-Year

1 October to 31 March

Due date within 60 days from 31 March.

Accordingly, companies generally file PAS-6 by 29 November for the half-year ending 30 September and 30 May for the half-year ending 31 March.

Practical Compliance Process

The practical compliance process may be summarized as follows:

  1. Determine applicability of Rule 9A or Rule 9B.
  2. Appoint a Registrar and Share Transfer Agent (RTA).
  3. Obtain ISIN for each class of security.
  4. Establish connectivity with NSDL/CDSL.
  5. Facilitate dematerialization of securities.
  6. Reconcile company records with depository records.
  7. Obtain certification from a PCS or CA.
  8. File PAS-6 with ROC within the prescribed time.

Consequences of non-compliance

Failure to comply with PAS-6 filing requirements may attract penalties under Section 450 of the Companies Act, 2013, where no specific penalty is prescribed.

The company and officers in default may be liable for monetary penalties for continuing non-compliance.

Company: ₹10,000 + ₹1,000/day (Max ₹2,00,000)

Officer in default: ₹10,000 + ₹1,000/day (Max ₹50,000)

Missing PAS-6 filing deadline results in:

Non-compliance under Rule 9A

Possible disqualification of directors

Hindrance in filing other forms

Higher scrutiny by regulators

The introduction of Rules 9A and 9B reflects the transparent and fully digitalised securities ecosystem. Obtaining an ISIN, facilitating dematerialization, reconciling share capital records, and filing Form PAS-6 are now essential compliance requirements for many unlisted public and private companies.

PAS-6 serves as an important regulatory tool that ensures consistency between company records and depository records while strengthening investor confidence and corporate governance standards.
