Medium-Term Investments [Abstract]

MEDIUM-TERM INVESTMENTS

NOTE 5: MEDIUM-TERM INVESTMENTS

We held investments in money market and other money funds at The Reserve, an investment management company specializing in such funds, as follows: June 30, 2011 — $0, December 31, 2010 — $5,531,000 and June 30, 2010 — $5,532,000. The substantial majority of our investment was held in the Reserve International Liquidity Fund, Ltd. On September 15, 2008, Lehman Brothers Holdings Inc. filed for bankruptcy protection. In the following days, The Reserve announced that it was closing all of its money funds, some of which owned Lehman Brothers securities, and was suspending redemptions from and purchases of its funds, including the Reserve International Liquidity Fund.

As a result of the temporary suspension of redemptions and the uncertainty as to the timing of such redemptions, during 2008 we changed the classification of our investments in The Reserve funds from cash and cash equivalents to medium-term investments. We reduced the carrying value of our investment to its estimated fair value of $3,630,000 and $3,910,000 as of December 31, 2010 and June 30, 2010, respectively. See Note 7 for further discussion of the fair value determination.

During January 2011, we received $3,630,000 from the Reserve representing the final redemption of the investment. As a result of this redemption, we reclassified our investments in The Reserve funds from medium-term investments to cash and cash equivalents as of December 31, 2010.
