Operational Guidelines for Switch/Conversion Transactions with the Government of
India
Switch module on e-Kuber
1. The market participants can bid in the switch auction through the Switch Transaction
module provided in the e-Kuber portal.
Bidding in a switch transaction
2. Bidding in the auction implies that the market participants agree to sell the source
security/ies to the Government of India (GoI) and simultaneously agree to buy the destination
security from the GoI at their respective quoted prices.
Placing of bids
3. Each bid should specify the following details:
I. Amount of the source security (Face Value) that the participants are willing to sell.
II. Price of the source security (expressed up to two decimal places).
III. Choice of destination security and the price of the destination security (expressed up
to two decimal places), at which the participants are willing to buy the destination
security.
4. The participants can choose to bid for any/all the destination security/ies, but the aggregate
amount of bids for the source security should not exceed their holdings of the source security
in face value terms.
Minimum Bid size
5. Minimum bid size would be ₹10,000 and in multiples of ₹10,000 thereafter. The participants
are allowed to submit multiple bids. However, the aggregate amount of bids submitted should
not exceed the notified amount of source security/basket of source securities in the auction.
Price of source security
6. The price of the source security quoted must be equal to the FBIL closing price of the
source security as on the previous working day.
7. Bids for source security not as per the price mentioned above will be rejected.
Price of destination security
8. Bids for the destination security may be placed after taking into account the price of source
security as mentioned above.
Method of auction
9. The auction will be a multiple-price based auction, i.e. successful bids will get accepted at
their respective quoted prices for the source and destination securities.
Auction decision
10. The auction cut-off will be decided based on the price of the destination security/ies.
11. Successful bidders are those who have placed their bids at or above the cut-off price. All
bids lower than the cut-off price will be rejected.
12. There will be provision of pro-rata allotment, should there be more than one successful bid
at the cut-off price.Amount of destination security and dealing in odd amounts during switch auction
13. The switch ratio, which is the ratio of the price of the source security to the price of the
destination security, would be rounded off at 8 decimal places.
14. The amount of destination security to be issued for each successful bid will be computed
by multiplying the allotted amount (FV) of the source security with the rounded-off switch ratio.
The amount of destination security (FV) would be rounded-off to the nearest lower value in
multiples of ₹10,000.
15.The odd amount of destination securities (less than₹10,000) which has been rounded-off,
would be notionally allotted and bought back from the bidders at the quoted bid price of the
destination security. The net cash consideration to be paid to the bidder for such odd amounts
would be the clean price of these securities (as the accrued interest received during notional
allotment and paid during notional buyback offset each other).
Fund settlement
16. Though the conversion would be broadly cash neutral, there will be fund settlement for the
net accrued interest (accrued interest for the source security FV – accrued interest for the
destination security FV) for each bid. Cash consideration (due to rounding-off of face value of
destination security) computed for each bid would be added to the net accrued interest.
Accordingly, fund settlement will be done for the final amount (Net accrued interest + cash
consideration) for each bid.
Note: An illustration for the calculation of cash consideration due to rounding-off of
destination security face value is as given below:
Amount of Source Security (FV) ₹10,00,00,000.00
Price of Source Security ₹97.50
Price of Destination Security ₹99.20
Switch Ratio (rounded-off at 8 decimals) 0.98286290
Destination Security FV before rounding off ₹9,82,86,290.00
Destination Security FV re-issued after rounding-off ₹9,82,80,000.00
Odd amount of rounded-off destination security (FV) ₹6290.00
Cash consideration due to rounding off (Clean Price ₹6240.00
calculated at the quoted price of destination security)
17. The settlement of the auction would be held on T+1 basis.
