However, to accurately reflect your HINDUNILVR investment after the demerger, a manual update of the cost price will be required.

Why a Manual Update Is Needed

After a demerger, the total cost of your original investment needs to be redistributed between the two resulting companies.

For this demerger:

• 98.09% of the original cost is allocated to HINDUSTAN UNILEVER LIMITED (HINDUNILVR)

• 1.91% of the original cost is allocated to KWALITY WALLS INDIA LIMITED (KWIL)

This ensures your portfolio correctly reflects the adjusted value of both holdings.

Steps to Update your Portfolio for HINDUSTAN UNILEVER LIMITED (HINDUNILVR)

To update your portfolio correctly, please follow the steps below and in the exact order:

1. Close your existing HINDUNILVR buy transactions

You are required to manually add sell transactions for each of your earlier buy transactions of HINDUNILVR.

This step resets current HINDUNILVR quantity in the system and you will be able to add revised cost allocation for HINDUNILVR holdings.

2. Add a revised HINDUNILVR buy transaction

Create a new buy entry for HINDUNILVR using the 98.09% cost allocation.

While adding this entry, ensure that:

• The quantity remains the same as your original HINDUNILVR holding (because there is no change in the number of HINDUNILVR shares on account of demerger).

• The transaction date is the same as your original purchase date.

• The revised cost price is calculated using the cost apportionment formula below.

For example,

Say you purchased 50 shares of HINDUNILVR on 01/04/2025 (i.e., on or before the record date) at a price of ₹2,000 per share, and assuming you paid ₹100 towards brokerage and statutory charges, then your total transaction cost becomes ₹1,00,100, resulting in an average cost of ₹2,002 per share.

If you wish to update the revised buy entries for this transaction, the calculation will be as follows:

Revised Buy Price = [ Total Transaction Cost (including brokerage & charges) × 98.09%] ÷ Quantity

= [ ₹1,00,100 × 98.09%] ÷ 50= ₹1,963.76 (per share)

Steps to Update your Portfolio for KWALITY WALLS INDIA LIMITED (KWIL):

We will update your portfolio with the newly allotted KWALITY WALLS INDIA LIMITED (KWIL) shares on or before February 24, 2026. If your portfolio is not updated automatically, then you can update it by following the steps below:

 Add a buy transaction using the cost Apportionment ratio:

A. Transaction Date: Date of purchase of original shares of HINDUSTAN UNILEVER LIMITED (HINDUNILVR)

    Quantity: The demerger ratio is 1:1, so the quantity will be the same as the number HINDUNILVR shares in your portfolio as on the record date

B. Cost Price Calculation = [Total transaction cost (incl. brokerage & statutory charges) × 1.91%] ÷ Quantity

Using the same example: 

Cost Price = [Total Transaction Cost (including brokerage & charges) × 1.91%] ÷ Quantity 

= [₹100,100 × 1.91%] ÷ 50

= ₹38.24 (per share)
