Share-based Compensation Arrangement by Share-based Payment Award [Line Items]                      
Description of stock option plan         Under the Company’s stock option plans (the 1999 Stock Option Plan and the 2003 Stock Option Plan), the Company was able to grant options for up to a combined total of 1,622,500 shares of common stock to employees, officers and directors.  Shares issued may be purchased in the open market or may be issued from authorized and unissued shares.  The exercise price of each option equals the fair market value of the Company’s common stock on the date of grant.   The Company adopted the Management Recognition and Development Plan (“MRDP”) in 1998 for the benefit of employees, officers and directors of the Company.  The objective of the MRDP is to retain and attract personnel of experience and ability in key positions by providing them with a proprietary interest in the Company.
