Item 8.01 Other Events.

Cardinal Financial Corporation (the "Company") currently holds perpetual preferred stock issued by Fannie Mae in its available-for-sale investment securities portfolio with a book value of $4.8 million. The Company expects to record a noncash other-than-temporary impairment charge on these securities in the third quarter, as these securities now trade well below their par value. The Company will continue to evaluate the situation and expects to make a final determination of impairment relating to these securities in connection with the preparation of its financial statements for the third quarter of 2008.

The expected impairment on these securities would not impact the Company's nor its subsidiary bank's ability to maintain capital ratios significantly above the "well capitalized" regulatory requirements.
