The inputs to the valuation techniques used to measure fair value are classified into the following categories:
Level 1 — Quoted prices in active markets for identical assets or liabilities
Level 2 — Quoted prices for similar assets and liabilities in active markets or inputs that are observable
Level 3 — Inputs that are unobservable (for example, cash flow modeling inputs based on assumptions)
As of December 31, 2013, the Company’s investment in cash and cash equivalents of $90.7 million and long-term investments, classified as restricted cash on the Consolidated Balance Sheets, of $2.6 million, were measured at fair value using Level 1 inputs. During the year ended December 31, 2013, there were no transfers in or out of the Company’s Level 1 assets.
