Fannie Mae’s net interest income has barely changed over the past 13 quarters, while Freddie Mac’s has increased slightly in all but one of those quarters. (Includes data table.)

Fannie Mae belatedly joined Freddie Mac in establishing ground rules for seller/servicers that deploy or manage artificial intelligence or machine learning tools while doing business with the enterprise.

Fannie Mae extended duration by shifting from short- to long-term debt, but allowed overall debt to grow. Freddie de-levered by cutting short-term debt without adding to long-term debt.
