Investments [Abstract]
Investments	Note 3 — Investments In 2008 we invested in auction rate preferred securities of closed-end funds (“ARPS”) to maximize interest income. We considered investments in these instruments as available for sale in accordance with relevant accounting guidance. ARPS have historically been liquid but have been adversely affected by the broader national liquidity crisis. We entered into an agreement with our investment advisor, Stifel Nicolaus, to repurchase 100% of the remaining ARPS at par on or prior to June 30, 2012. We have established a line of credit to borrow against 80% of these investments so that sales of these securities would not have to occur in order to fund our operating needs. The balance of the investments is classified as short-term as of September 30, 2011. As of September 30, 2011, in light of the plan for repurchase and the repurchases made during the year, management has determined that there has not been a change in the fair value of the securities owned. We have not recorded any impairment related to these investments, as management does not believe that the underlying credit quality of the assets has been impacted by the reduced liquidity of these investments. In addition, no unrealized gain or loss has been recorded on these assets. We consider the inputs to valuation of these securities as level 2 inputs in the fair value hierarchy.

Note 3 — Investments

In 2008 we invested in auction rate preferred securities of closed-end funds (“ARPS”) to maximize interest income. We considered investments in these instruments as available for sale in accordance with relevant accounting guidance.

ARPS have historically been liquid but have been adversely affected by the broader national liquidity crisis. We entered into an agreement with our investment advisor, Stifel Nicolaus, to repurchase 100% of the remaining ARPS at par on or prior to June 30, 2012.

We have established a line of credit to borrow against 80% of these investments so that sales of these securities would not have to occur in order to fund our operating needs. The balance of the investments is classified as short-term as of September 30, 2011.

As of September 30, 2011, in light of the plan for repurchase and the repurchases made during the year, management has determined that there has not been a change in the fair value of the securities owned. We have not recorded any impairment related to these investments, as management does not believe that the underlying credit quality of the assets has been impacted by the reduced liquidity of these investments. In addition, no unrealized gain or loss has been recorded on these assets. We consider the inputs to valuation of these securities as level 2 inputs in the fair value hierarchy.
