(1) In connection with the net share settlement of the exercise of 4,000 vested stock appreciation rights ("SARs") granted in January 2015 with a grant price of $28.17 per share, Mr. Covington was entitled to receive 2,763 shares of the Federal Agricultural Mortgage Corporation's ("Farmer Mac") Class C Non-Voting Common Stock. None of these shares were sold, as Mr. Covington retained 1,710 shares, and Farmer Mac retained 1,053 shares to satisfy tax withholding requirements arising from the exercise. The 1,237 shares reported as a disposition to the issuer of issuer equity securities represents the difference between the number of SARs exercised and the number of shares issuable as a result of the exercise. Each SAR represents the right to receive, upon exercise, the number of shares of Farmer Mac's Class C Non-Voting Common Stock equal to the excess of the fair market value of shares on the exercise date over the grant price.
(2) Transaction effected during an open trading window for employees and directors of Farmer Mac.
(3) Includes 9,708 shares of unvested restricted stock previously granted pursuant to Farmer Mac's Amended and Restated 2008 Omnibus Incentive Plan. The grants of restricted stock have been described in detail in Farmer Mac's prior filings with the Securities and Exchange Commission.

None of these shares were sold, as Mr. Covington retained 1,072 shares, and Farmer Mac retained 661 shares to satisfy tax withholding requirements arising from the exercise. The 957 shares reported as a disposition to the issuer of issuer equity securities represents the difference between the number of SARs exercised and the number of shares issuable as a result of the exercise. Each SAR represents the right to receive, upon exercise, the number of shares of Farmer Mac's Class C Non-Voting Common Stock equal to the excess of the fair market value of shares on the exercise date over the grant price.
(5) In connection with the net share settlement of the exercise of 3,412 vested SARs granted in March 2016 with a grant price of $35.75 per share, Mr. Covington was entitled to receive 2,072 shares of the Farmer Mac's Class C Non-Voting Common Stock. None of these shares were sold, as Mr. Covington retained 1,282 shares, and Farmer Mac retained 790 shares to satisfy tax withholding requirements arising from the exercise. The 1,340 shares reported as a disposition to the issuer of issuer equity securities represents the difference between the number of SARs exercised and the number of shares issuable as a result of the exercise. Each SAR represents the right to receive, upon exercise, the number of shares of Farmer Mac's Class C Non-Voting Common Stock equal to the excess of the fair market value of shares on the exercise date over the grant price.
(6) In connection with the net share settlement of the exercise of 1,619 vested SARs granted in March 2017 with a grant price of $60.84 per share, Mr. Covington was entitled to receive 537 shares of the Farmer Mac's Class C Non-Voting Common Stock. None of these shares were sold, as Mr. Covington retained 332 shares, and Farmer Mac retained 205 shares to satisfy tax withholding requirements arising from the exercise. The 1,082 shares reported as a disposition to the issuer of issuer equity securities represents the difference between the number of SARs exercised and the number of shares issuable as a result of the exercise. Each SAR represents the right to receive, upon exercise, the number of shares of Farmer Mac's Class C Non-Voting Common Stock equal to the excess of the fair market value of shares on the exercise date over the grant price.
