5.	Fair Value Measurements

Our auction rate securities are recorded at fair value in the accompanying Consolidated Balance Sheets in accordance with ASC 320 Investments – Debt and Equity Securities. The change in the fair value of these investments is recorded as a component of accumulated other comprehensive loss (see Note 2. Summary of Significant Accounting Policies - Fair Value Measurements in the notes to consolidated financial statements included in our 2012 Annual Report on Form 10-K).

Cash and cash equivalents of $79,221 at June 30, 2013 include cash of $8,876 and money market funds of $70,345. The following tables present our money market funds and auction rate securities measured at fair value on a recurring basis as of the dates indicated, classified by valuation hierarchy:

At June 30, 2013 we held $2,208 in auction rate securities which are classified as Level 3. The fair value of these securities includes $2,208 of U.S. government subsidized securities collateralized by student loan obligations, with maturities greater than 10 years. We will not realize cash in respect of the principal amount of these securities until the issuer calls or restructures the security, the security reaches any scheduled maturity and is paid, or a buyer outside the auction process emerges. As of June 30, 2013, we have received all scheduled interest payments on these securities, which, in the event of auction failure, are reset according to contractual terms in the governing instruments.

The valuation of auction rate securities we hold is based on Level 3 unobservable inputs which consist of our internal analysis of (i) timing of expected future successful auctions or issuer calls of the securities, (ii) collateralization of underlying assets of the security and (iii) credit quality of the security. We use a discounted cash flow model to estimate the value of these auction rate securities and the unobservable inputs consist of a redemption period ranging from five to 15 years (weighted-average: 6 years) and discount rates ranging from 0.375% to 2.031% (weighted-average: 1.23%). Significant increases (decreases) in the redemption period or discount rates would result in a significantly lower (higher) fair value measurement. In re-evaluating the valuation of these securities as of June 30, 2013, the temporary impairment amount, the duration of which is greater than 12 months, decreased from $260 at December 31, 2012, to $192, which is reflected as part of accumulated other comprehensive loss on our accompanying Consolidated Balance Sheets and based on such re-evaluation, we believe that we have the ability to hold these securities until recovery of fair value. Due to the uncertainty related to the liquidity in the auction rate security market and therefore when individual positions may be liquidated, we have classified these auction rate securities as long-term assets on our accompanying Consolidated Balance Sheets. We continue to monitor markets for our investments and consider the impact, if any, of market conditions on the fair market value of our investments. We do not believe the carrying values of our investments are other than temporarily impaired and therefore expect the positions will eventually be liquidated without significant loss.

For those financial instruments with significant Level 3 inputs (all of which are auction rate securities), the following table summarizes the activities for the periods indicated:
