This excerpt taken from the AN 10-K filed Feb 17, 2010.
In May 2009, the FASB issued an accounting standard that establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. This accounting standard is effective for interim or annual financial periods ending after June 15, 2009. The adoption of this standard did not have an impact on our Consolidated Financial Statements for the year ended December 31, 2009, as it is our continuing policy to evaluate subsequent events through the date our financial statements are issued. For the annual period ended December 31, 2009, we have evaluated subsequent events through February 17, 2010, which is the date our financial statements were issued and filed with the SEC.
