A consolidated account statement, or CAS, brings securities transactions and holdings together so an investor can review records across accounts. It can include demat accounts with the two depositories and mutual fund units held in statement-of-account form. It is a record of investments, rather than a recommendation about which investment to make.

The practical questions are usually about missing accounts, delivery frequency and downloading another copy. CDSL marks its CAS FAQ as last updated on 13 July 2020; it remained available when checked on 4 November 2026. The answers depend on PAN matching, the pattern in which an account is held and the issuer of the statement. SEBI's investor explanation of CAS says investors should keep their PAN updated with their depository participant or stock broker.

QuestionWhat to check
What joins the records?PAN, with the first holder and holding pattern relevant for joint holdings
When is it sent?CDSL describes monthly delivery when there are transactions and half-yearly holding statements when there are none
Who corrects an account detail?The relevant depository participant or mutual fund record keeper

What does a consolidated account statement contain?

The CDSL CAS FAQ describes a combined view of holdings and transactions in demat accounts with CDSL and NSDL, alongside mutual fund units held with mutual fund registrars in statement-of-account form. That last distinction matters: an investment record with a fund registrar is not necessarily a demat account.

CDSL lists fund purchases, redemptions, switches, dividend reinvestments and systematic transactions among the entries supplied by mutual fund registrars. Demat transactions are also included. When reading the document, separate the opening position, changes during the statement period and closing position. A purchase entry and the resulting holding describe different parts of the same record, so adding both together would double-count it.

Consider a simple record-checking example. An investor starts a period with 100 units, purchases 20 and redeems 10. With no other unit changes, the closing quantity is 110 units. This is arithmetic to reconcile quantities, not an illustration of investment returns. A change in market value cannot by itself explain a discrepancy in the number of units shown.

Why might an account be missing from CAS?

Consolidation is based on PAN. For multiple holders, CDSL says the PAN of the first holder and the pattern of holding are relevant. An individually held account and a jointly held account should therefore not automatically be expected to appear as though they have identical ownership. Compare the names and their order before assuming a record has disappeared.

For PANs common to the depositories and mutual fund records, the depositories send the consolidated statement. Where the investor holds only mutual fund units without a demat account, the fund houses or their registrars continue to send CAS. The existence of the same acronym does not mean every statement comes from the same organisation or follows the same retrieval screen.

There is also a specific exception in CDSL's FAQ: where mutual fund units are held only in demat form, it says CAS is not generated under the arrangement it describes and the respective participant sends the demat transaction statement. Before treating a missing CAS as a service failure, establish whether the expected document is actually a participant statement.

When is CAS sent, and how can you get a duplicate?

CDSL says a transaction in any covered demat account or mutual fund folio triggers monthly CAS delivery. If there are no transactions across those records, it describes a half-yearly statement of holdings, with March-end and September-end holdings sent in April and October respectively. A quiet investment account may therefore have a different statement rhythm from one receiving regular transactions.

For investors with accounts across both depositories, CDSL describes the depository associated with the earlier-opened demat account as the default sender. It also says an investor can request a change through the participant of the default depository. Receiving one combined document does not mean the other depository account has been closed or moved.

To receive CDSL statements by email, update the email address with the CDSL participant and provide consent for emailed transaction statements. For a duplicate, the FAQ directs investors to the CAS tab on the official CDSL website. Use the issuer's own route and check that it is a CDSL statement before applying CDSL-specific instructions to it.

CDSL's FAQ says the password for its protected e-CAS is the PAN of the first or sole demat holder in capital letters. That instruction concerns opening an already-issued document. It is not a reason to disclose PAN, a password or an authentication code to someone offering unsolicited assistance.

How to check a statement without confusing it with returns

Match the statement period, ownership details, account identifiers and quantities against the records from the relevant participant or fund. If something differs, identify the particular transaction and the organisation maintaining that record. A consolidated view is useful for spotting a question; the underlying account record is needed to resolve it.
