TSX Buy-Ins
In order to support CDS in cases where a seller has failed to deliver a security following a trade, TSX has developed a special "Buy-In" facility to locate alternate sellers capable of immediately delivering the security, therefore enabling CDS to quickly and efficiently clear the failed position.
Buy-In Procedures
On a daily basis, CDS provides a list of securities that Participating Organizations have failed to make delivery on.
| TIME (ET) | Procedures |
|---|---|
| 12:30 PM (1st Cycle) | TSX receives and posts the preliminary Buy-In list. At this point, other Participating Organizations have the opportunity to provide liquidity by submitting Buy-In orders. |
| 2:00 PM (2nd Cycle) | TSX receives and posts the Final Buy-In list. This list identifies the remaining securities that still need to be delivered. |
| 2:30 PM | Cut-off for accepting Buy-In orders. |
Upon completion of the Buy-In period, TSX allocates fills on an equal by member basis to the sellers and calculates a price. This price is based on the last board lot trade before 2:30 p.m. plus a premium.
Buy-In Price = Last Board Lot Sale Price + Premium
TSX manually enters these trades under a generic trader ID for each PO that are cleared by CDS on a same-day basis. Between 2:50 p.m. and 3:10 p.m., TSX Trading Services will provide transaction confirmations. This process efficiently clears failed delivery trades and helps to maintain overall market integrity.
