(1) Recorded at cost plus accrued interest, which approximates fair value.

(2) Amounts may be redeemed on a daily basis as presented to the original issuer.

(3) Recorded at fair value as determined by quoted market prices (see amounts presented in the table of financial assets measured at fair value within this note).

(4) Amounts restricted for use are subject to change based on the requirements of the Company’s collateralized facilities (see Note D).

The Company’s long-term investment financial instruments are presented in the table of financial assets measured at fair value within this note.

Concentrations of Credit Risk of Financial Instruments

The Company is potentially subject to concentrations of credit risk related to its cash, cash equivalents and short-term investments. The Company reduces credit risk by placing its cash, cash equivalents and short-term investments with major financial institutions and corporate issuers that have high credit ratings and by investing unrestricted short-term investments primarily in FDIC-insured certificates of deposit with varying original maturities of ninety-one days to one year. However, certain cash deposits and certificates of deposit, primarily those pledged as collateral for outstanding letters of credit (see Note D), may exceed federally insured limits. At June 30, 2011 and December 31, 2010, cash and certificates of deposit of $47.4 million and $48.1 million, respectively, exceeded FDIC-insured limits.

Financial Assets Measured at Fair Value

Fair value measurements are based on observable and unobservable inputs of market data and market assumptions. These inputs form a three-level valuation hierarchy as follows:

· Level 1 — Quoted prices for identical assets and liabilities in active markets.

· Level 2 — Quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.

· Level 3 — Unobservable inputs (Company’s market assumptions) that are significant to the valuation model.

The following table presents, for each of the fair value hierarchy levels, the assets that are measured at fair value on a recurring basis:

(1) Included in cash equivalents and restricted cash equivalents.

(2) Consists of an insured available for sale auction rate debt security for which the underlying debt instrument matures in 2025. The security is valued using the income approach with inputs derived from observable market data and recorded at fair value plus accrued interest in other long-term assets. An unrealized gain, net of taxes, related to the security was included in accumulated other comprehensive loss as of June 30, 2011 and December 31, 2010 (see Note F).

(3) Nonqualified deferred compensation plan investments consist of U.S. and international equity mutual funds, government and corporate bond mutual funds and money market funds which are held in a trust with a third-party brokerage firm. Quoted market prices are used to determine fair values of the investments which are included in other long-term assets, with a corresponding liability reported within other long-term liabilities.
