Freddie Mac said it would sell $1.5 billion bills later today.
The sale will include $1 billion three-month bills, due May 21, 2012, and $500 million six-month bills, due Aug 20, 2012.
Settlement is Feb. 22.
The bills will be sold over the Internet in a Dutch auction. In such uniform price auctions, successful bidders pay only the price of the lowest accepted bid rather than the actual price as in a conventional multiple-price auction.
Bids will be accepted from authorized dealers from 8:00 a.m. (1300 GMT) until 9:45 a.m. (1445 GMT). Reuters reported.
