AGNC Declares $1.40 Fourth Quarter Dividend

December 18, 2009

BETHESDA, Md., Dec 18, 2009 /PRNewswire-FirstCall via COMTEX/ -- American Capital Agency Corp. (Nasdaq: AGNC) ("AGNC" or the "Company") announced today that its Board of Directors has declared a cash dividend of $1.40 per share for the fourth quarter 2009. The dividend is payable on January 26, 2010 to common shareholders of record as of December 31, 2009, with an ex-dividend date of December 29, 2009.

The Company anticipates that the total dollar amount of undistributed taxable income will increase from September 30, 2009 and expects to incur a Federal excise tax. As a real estate investment trust ("REIT"), the Company is subject to a 4% annual Federal excise tax to the extent that the sum of (i) 85% of its ordinary taxable income, (ii) 95% of its capital gains and (iii) any undistributed taxable income from the prior year exceeds its distributions for such year. However, the Company does expect to distribute all of its taxable income for the 2009 fiscal year to its shareholders during 2010 in order to avoid any income taxes. As a REIT, the Company may distribute its current undistributed taxable income in the subsequent year if it is declared by the extended due date of its income tax return and paid by the end of the subsequent year.
