ExpressJet Holdings, Inc. missed its March 17 deadline for filing its 10K in an announcement released yesterday. The airline had said it would file last Friday during its year-end conference call last week. The company cannot complete the Form 10-K by the due date because it continues to assess the current marketability of approximately $65 million face value of auction-rate securities it purchased in early 2008. XJT intends to file the Form 10-K as soon as practicable, and in no event later than the fifteenth calendar day following the prescribed due date. It will file Form 12b-25 permitting the company to file the 2007 Annual Report late.
