Long-term Investments [Abstract]
Long-term Investments	Long-term Investments As of September 30, 2013 and June 30, 2013, the Company held $2,637,000 of auction-rate securities (“auction rate securities”), net of unrealized losses, representing its interest in auction rate preferred shares in a closed end mutual fund invested in municipal securities; such auction rate securities were rated AAA or AA2 at September 30, 2013 and June 30, 2013. These auction rate preferred shares have no stated maturity date. During February 2008, the auctions for these auction rate securities began to fail to obtain sufficient bids to establish a clearing rate and the securities were not saleable in the auction, thereby losing the short-term liquidity previously provided by the auction process. As a result, as of September 30, 2013 and June 30, 2013, $2,637,000 of these auction rate securities have been classified as long-term available-for-sale investments. The Company has used a discounted cash flow model to estimate the fair value of the auction rate securities as of September 30, 2013 and June 30, 2013. The material factors used in preparing the discounted cash flow model are i) the discount rate utilized to present value the cash flows, ii) the time period until redemption and iii) the estimated rate of return. As of September 30, 2013, the discount rate, the time period until redemption and the estimated rate of return were 1.65%, 3 years and 0.33%, respectively. Management derives the estimates by obtaining input from market data on the applicable discount rate, estimated time to redemption and estimated rate of return. The changes in fair value have been primarily due to changes in the estimated rate of return and a change in the estimated redemption period. The fair value of the Company's investment portfolio may change between 1% to 3% by increasing or decreasing the rate of return used by 1% or by increasing or decreasing the term used by 1 year. Changes in these estimates or in the market conditions for these investments are likely in the future based upon the then current market conditions for these investments and may affect the fair value of these investments. On a quarterly basis, the Company reviews the inputs to assess their continued appropriateness and consistency. If any significant differences were to be noted, they would be researched in order to determine the reason. However, historically, no significant differences have been noted. The Company has consistently applied these valuation techniques in all periods presented and believes it has obtained the most accurate information available for the auction rate securities. Movement of these inputs would not significantly impact the fair value of the auction rate securities. Based on this assessment of fair value, the Company determined there were no changes in the fair value of its auction rate securities during the three months ended September 30, 2013 and 2012. There was a cumulative total decline of $113,000 as of September 30, 2013 and June 30, 2013. That amount has been recorded as a component of other comprehensive income. As of September 30, 2013 and June 30, 2013, the Company has recorded an accumulated unrealized loss of $68,000, net of deferred income taxes, on long-term auction rate securities. The Company deems this loss to be temporary as it will not likely be required to sell the securities before their anticipated recovery and the Company has the intent and financial ability to hold these investments until recovery of cost. Although the investment impairment is considered to be temporary, these investments are not currently liquid and in the event the Company needs to access these funds, the Company will not be able to do so without a loss of principal. The Company plans to continue to monitor the liquidity situation in the marketplace and the creditworthiness of its holdings and will perform periodic impairment analysis. During the three months ended September 30, 2013 and 2012, there were no auction rate securities redeemed or sold.
