Fair Value Instruments

Note 4. Fair Value Instruments

The carrying value of financial instruments classified as current assets and current liabilities approximate fair value due to their liquidity and short-term nature. Investments that are classified as available-for-sale are recorded at fair value, which was determined using quoted market prices, broker dealer quotations, or alternative pricing sources with reasonable levels of price transparency. The Company’s portfolio of available-for-sale securities comprises U.S. Treasuries, U.S. government sponsored agency obligations and high credit quality corporate debt securities classified as available-for-sale securities.

Financial assets and liabilities measured at fair value are classified in their entirety in the fair value hierarchy, based on the lowest level input significant to the fair value measurement. The following table classifies the Company’s financial assets and liabilities measured at fair value on a recurring basis at June 30, 2016 and December 31, 2015, respectively in the fair value hierarchy:

There are no other financial instruments subject to fair value measurement on a recurring basis. Transfers to/from Levels 1, 2 and 3 are recognized at the end of the reporting period. There were no transfers between levels for the three and six months ended June 30, 2016 or 2015.  

Level 1 instruments include investments in money market funds and U.S. Treasuries. These instruments are valued using quoted market prices for identical unrestricted instruments in active markets. The Company defines active markets for debt instruments based on both the average daily trading volume and the number of days with trading activity. Level 2 instruments include U.S. Government agency obligations and corporate debt securities. Valuations of Level 2 instruments can be verified to quoted prices, recent trading activity for identical or similar instruments, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency. Consideration is given to the nature of the quotations (e.g. indicative or firm) and the relationship of recent market activity to the prices provided from alternative pricing sources.

Fair values of these assets are based on prices provided by independent market participants that are based on observable inputs using market-based valuation techniques. These valuation models and analytical tools use market pricing or similar instruments that are both objective and publicly available, including matrix pricing or reported trades, benchmark yields, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids and/or offers. The Company did not adjust any of the valuations received from these third parties with respect to any of its Level 1 securities for the periods ended June 30, 2016 or December 31, 2015.
