Since inception, the Company has made certain fair value estimates that are not recurring, generally related to share values and expected volatility, compensation expense and interest expense. Such estimates involve management’s review of available information of comparable companies and are therefore, generally nonobservable Level 3 inputs.

Concentrations of Credit Risk

Cash, cash equivalents and accounts receivable potentially subject the Company to concentration of credit risk. Cash and cash equivalents are held at U.S. FDIC-insured financial institutions and the amounts on deposit are sometimes above the FDIC insured limits of up to $ per account.

Intangible Assets

The Company records acquired intangible assets based on fair value on the date of acquisition. Finite-lived intangible assets are recorded at cost and amortized on a straight-line basis over the estimated lives of the assets. Indefinite-lived intangible assets are not subject to amortization.
