3. Fair Value of Financial Instruments

The Company measures certain financial assets at fair value on a recurring basis based on a fair value hierarchy that requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs. Inputs used in the valuation techniques to derive fair values are classified based on a three-level hierarchy, as follows:

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

· Level 2 — Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities.

· Level 3 — Unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities.

As of June 30, 2014 and December 31, 2013, financial assets measured at fair value on a recurring basis were comprised of money market funds and certificates of deposit included within cash and cash equivalents.

The fair value of these financial assets was determined using the following inputs for the periods presented:

	June 30, 2014						December 31, 2013
	Level 1		Level 2		Level 3		Level 1		Level 2		Level 3
