Subsequent Events [Abstract] |
Subsequent Events [Text Block] | SUBSEQUENT EVENT On February 19, 2019, we purchased a $546 million portfolio of participations in seasoned Rural Utilities loans from CoBank under a master loan participation agreement entered into on February 13, 2019. CoBank is a related party to Farmer Mac because of its stock ownership in Farmer Mac. For more information, see the Current Report on Form 8-K that we filed with the SEC on February 20, 2019. As discussed in Note 3, Farmer Mac has a related party relationship with CoBank because CoBank is a major holder (32.6%) of Farmer Mac Class B voting common stock and because a member of Farmer Mac's board of directors has an affiliation with that entity.
