Chimera Investment Corporation Announces September 30, 2012 Estimated GAAP Book Value of $3.31 per Share16:05 EST Thursday, December 13, 2012 NEW YORK (Business Wire) -- Chimera Investment Corporation (NYSE: CIM) announced today that it has estimated that as of September 30, 2012, its GAAP book value was $3.31 per share and its economic book value was $2.95 per share, compared to its estimated June 30, 2012, GAAP book value of $3.08 per share and economic book value of $2.87 per share. Estimated economic book value considers the fair values of only the assets the Company owns or is able to dispose of, pledge, or otherwise monetize, and specifically excludes assets consolidated for GAAP but which the Company cannot dispose of, pledge or otherwise monetize. The Company's estimate of economic book value has important limitations. Should the Company sell the assets in its portfolio, it may realize materially different proceeds from the sale than estimated as of the reporting date. The Company had previously announced that it would delay the filing of its Form 10-K for the year ended December 31, 2011, and its Forms 10-Q for the quarters ended March 31, 2012, June 30, 2012, and September 30, 2012. The Company announced that the Company's previously filed Annual Reports on Form 10-K for the years ended December 31, 2010, 2009 and 2008, and the Quarterly Reports on Form 10-Q beginning with the quarter ended September 30, 2008, and for all subsequent quarters through the quarter ended September 30, 2011, will be restated and can no longer be relied upon. The restatement is not expected to affect the Company's previously announced GAAP or economic book values, actual cash flows, dividends and taxable income for any previous period. The Company is currently unable to estimate the timing for filing its 2011 Form 10-K, and expects to file its Form 10-Q for the quarter ended March 31, 2012 within 60 days after it files its 2011 Form 10-K. Any subsequent unfiled Quarterly Reports will be filed as soon as practicable.
