The Company is working diligently to complete the restatement of its financial statements, however, the Company is unable to complete the restatement within the prescribed time period without unreasonable effort and expense. The Company believes that it will file its Annual Report on Form 10-K for the year ended December 31, 2011 on or before the fifteenth calendar day following the prescribed due date.

For the nine months ended September 30, 2011, the Company had previously reported net income of $24.8 million or $1.46 diluted earnings per share. Based on its initial estimates, the Company expects that diluted earnings per share for the first nine months of 2011 will be between $0.98 and $1.15. Based on such estimates, the Company expects to earn diluted earnings per share of between $1.20 and $1.35 for the year ended December 31, 2011 after the restatement.
