TYSONS CORNER, Va. -- Cardinal Financial Corporation (NASDAQ:CFNL) (the "Company") today announced that it plans to release its first quarter earnings by April 30, 2007. This quarterly earnings announcement is later than normal, and the sole reason is to provide the Company with more time to analyze the potential early adoption of Statement of Financial Accounting Standards No. 159, "The Fair Value Option for Financial Assets and Financial Liabilities." This accounting standard provides entities, such as Cardinal Financial, the ability to early adopt the measurement of certain identified assets or liabilities at fair value.
