[1] As of September 30, 2011 and December 31, 2010, Level 1 short-term investments include an investment in a tax-advantaged preferred security, for which we determined fair value based on the quoted market price of the underlying security.

[2] Level 3 short-term investments as of December 31, 2010 included an auction rate security invested in a tax-exempt state government obligation that was valued at par with a value of $0.4 million, or 0.1% of our total assets. Our intent was not to hold the auction rate security invested in a tax-exempt state government obligation to maturity, but rather to use the interest reset feature to provide liquidity. In October 2010, $1.1 million of this security was redeemed by the issuer at par. Due to continued failures in the marketplace auctions, we held the remaining $0.4 million auction rate security until the maturity date in September 2011, when it was redeemed by the issuer at par.

[3] Level 3 long-term investments as of December 31, 2010 included a tax-advantaged preferred stock of a financial institution with a fair value of $2.3 million, or 0.5% of total assets. As of December 31, 2010, it was uncertain whether we would be able to liquidate these securities within the next twelve months; as such we classified them as long-term on our consolidated balance sheet. Due to the lack of observable market quotes, we utilized valuation models that relied exclusively on Level 3 inputs including those that are based on expected cash flow streams, including assessments of counterparty credit quality, default risk underlying the security, discount rates and overall capital market liquidity. In June 2011, we sold this security for approximately $2.5 million and recorded a gain of approximately $0.4 million in our consolidated statement of operations.
