Fair Value Measurements [Abstract]

Fair Value Measurements

Note 6 — Fair Value Measurements

The Company uses the following methods and assumptions to estimate the fair value of financial instruments:

• Cash and Cash Equivalents — Reported amounts approximate fair value.

• Restricted Cash — Reported amounts approximate fair value.

• Accounts Receivable — Reported amounts, net of the allowance for doubtful accounts, approximate fair value.

• Accounts Payable, Including Income Taxes Payable and Accrued Expenses — Reported amounts approximate fair value.

• Long-Term Debt — The carrying amount of the Company’s floating-rate debt approximates fair value since the interest rates paid are based on short-term maturities and recent quoted rates from financial institutions.

• Preferred Stock Derivatives — Conversion and redemption rights associated with preferred stock, which were bifurcated based on an analysis of the features in relation to Series A, B, and C Preferred Stock, classified as a non-current liability and reported at approximate fair value, with changes in fair value being reported as other income (expense). All preferred stock derivatives were settled immediately prior to the Company’s IPO in December 2010 (see Note 3 — Initial Public Offering and Preferred Stock).
