| (1) |  | Cash, cash equivalents and restricted cash consist primarily of money market funds with original maturity dates of three months or less, for which fair value is determined through quoted market prices.
| (2) |  | Short-term investments are classified as other current assets and are comprised primarily of municipal bonds, the majority of which are rated Aa2 or better. The fair values of the municipal bonds are obtained from readily-available pricing sources for comparable instruments, and as such, the Company has classified these assets as Level 2.
| (3) |  | Investments in lieu of retainage are classified as account receivables, including retainage and are comprised of U.S. Treasury Notes and other municipal bonds, the majority of which are rated Aa3 or better. The fair values of the U.S. Treasury Notes and municipal bonds are obtained from readily-available pricing sources for comparable instruments, and as such, the Company has classified these assets as Level 2.
| (4) |  | On April 30, 2014, the Company sold its auction rate securities (“ARS”) for $44.5 million. At both March 31, 2014 and December 31, 2013 the Company had $46.3 million invested in these ARS which the Company considered as available-for-sale long-term investments. The long-term investments in ARS held by the Company at both March 31, 2014 and December 31, 2013 were in securities collateralized by student loan portfolios. At both March 31, 2014 and December 31, 2013, most of the Company’s ARS were rated AA+.
| (5) |  | As discussed in Note 10 — Financial Commitments, the Company entered into a swap agreement with Bank of America, N.A. to establish a long-term interest rate for its former $200 million five-year term loan. The swap agreement became effective for the term loan principal balance outstanding at January 31, 2012. This term loan was paid off and the then current amount refinanced on June 5, 2014, providing for a $250 million term loan maturing on June 5, 2019. The interest rate swap continues on its original basis for the initial term and amount and finalizes on June 30, 2016. The Company values the interest rate swap liability utilizing a discounted cash flow model that takes into consideration forward interest rates observable in the market and the counterparty’s credit risk. This liability is classified as a component of other long-term liabilities.
| (6) |  | The liabilities listed as of September 30, 2014 and December 31, 2013 above represent the contingent consideration for the Company’s acquisitions in 2011 for which the measurement periods for purchase price analyses for the acquisitions have concluded.
