Stock Purchase Agreement Disclosure [Abstract]
Stock Purchase Agreements	The Company has an agreement with the former chairman, in the event of his death, at the request of the executor of his estate, to repurchase his Company common stock from his estate. The Company does not have the right to require the estate to sell stock to the Company. As such, this arrangement is accounted for as a written put option with the fair value of the put option recorded as a derivative liability. As of June 30, 2017, the estate of the former chairman does not hold a material amount of Company stock. As such, there is no exposure that the executor of the former chairman's estate may require the Company to repurchase a material amount of stock in the event of his death. The repurchase price is 95% of the fair market value of the common stock on the date that notice to repurchase is provided to the Company. The total number of shares to be repurchased will be sufficient to provide proceeds which are the lesser of $2,500,000 or the amount of estate taxes and administrative expenses incurred by his estate. The Company may elect to pay the purchase price in cash or may elect to pay cash equal to 25% of the total amount due and to execute a promissory note at the prime rate of interest for the balance payable over four years. The Company maintains a $1,150,000 life insurance policy to fund a substantial portion of this obligation. In April 1995, the Board of Directors approved a stock repurchase program authorizing the Company to purchase from time to time up to $2,000,000 of its common stock for its own account. Subsequently, the Board of Directors periodically has approved increases in the amount authorized for repurchase under the program. As of June 30, 2017, the Board had authorized the repurchase of an aggregate of $45,500,000 of common stock under the stock repurchase program, of which $43,360,247 had been expended. No shares were repurchased in 2017 or 2016.
