Repurchase Operation Overview: Reference Notes® Securities

Overnight notice will be provided via the Freddie Mac website, designated dealers, and major news wires. In rare circumstances, less advance notice (at least one hour) may be given. Advance notice will include target issues, maximum repurchase size, and cutoff time for offerings.

Freddie Mac expects to provide an automated reply (confirmation of trade) to participating dealers within 5 minutes after the cutoff time.

Amount repurchased by issue, overall offer-to-cover ratio, will be posted within 15 minutes following completion of the operation.

Reference Notes securities of a similar maturity as that of scheduled Reference Notes securities offerings will not be repurchased during a lockout period beginning 1 week prior to the announcement date through the settlement date. Also, repurchases of Reference Notes securities will not be conducted within one week of the final CBOT delivery date.

Dealers make offerings, expressed in yield, via the Internet.

Multiple offerings will be permitted for each issue.

After the cutoff time, Freddie Mac will consider all offerings together and accept those offerings which best meet repurchase operation objectives. Offerings may be accepted in whole, in part, or rejected.

Only Reference Bonds securities and off-the-run Reference Notes securities will be repurchased.

The minimum outstanding amount of each Reference Notes securities issue following a repurchase will be $3 billion. For Reference Bonds securities, the minimum will be $1 billion.
