Effective as of November 8, 2011, the Board of Directors of the Company approved the voluntary delisting of its Common Stock, par value $0.4167 per share, from the NYSE Amex and the voluntary termination of the registration of the Common Stock under the Securities Exchange Act of 1934, as amended. In connection therewith, the Company notified NYSE Amex on November 14, 2011 of the Company’s intention to file a Form 25 on or about November 28, 2011. The Company anticipates that the Form 25 will become effective 10 days following its filing.
