Stock Repurchase Program
Stock Repurchase Program

On July 26, 2005, the Company’s Board of Directors authorized a program to repurchase up to a total of 1,500,000 shares of the Company’s common stock (the “2005 Stock Repurchase Program”).  The Company’s Board of Directors has authorized the 2005 Stock Repurchase Program through December 31, 2019.  The Company expects the purchases pursuant to the 2005 Stock Repurchase Program to be made from time to time in private transactions at a price equal to the most recent quarterly independent appraisal of the shares of the Company’s common stock and with the Board reviewing the overall results of the 2005 Stock Repurchase Program on a quarterly basis.  All purchases made pursuant to the 2005 Stock Repurchase Program since its inception have been made on that basis.  The amount and timing of stock repurchases will be based on various factors, such as the Board’s assessment of the Company’s capital structure and liquidity, the amount of interest shown by shareholders in selling shares of stock to the Company at their appraised value, and applicable regulatory, legal and accounting factors.  The Company has purchased 1,057,350 shares of its common stock in privately negotiated transactions from August 1, 2005 through March 31, 2018.  Of these 1,057,350 shares, 47,432 shares were purchased during the quarter ended March 31, 2018, at an average price per share of $56.78.
