Freddie Mac said the measure of its exposure to changes in portfolio value averaged $54 million in July, down from $60 million in June.  The duration gap was unchanged at an average of 1 month.  The elevated interest-rate exposure measures were due to the inclusion of Single-Family upfront fees risk into the company's asset and liability management strategy.
