Fair Value Measurements

3 Months Ended

Mar. 31, 2018

The Company’s fair value measurements are classified and disclosed in one of the following three categories:


•	Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;


•	Level 2: Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; and


•	Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).

There was no movement between level 1 to level 2 or between level 2 to level 3. The following table summarizes the valuation of the Company’s financial instruments that are measured at fair value on a recurring basis:



	March 31, 2018								December 31, 2017
			Fair value measurement category								Fair value measurement category
(In thousands)	Total		Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3
Liabilities:
Warrant liabilities	$	1,921	$	—	$	1,921	$	—	$	1,014	$	—	$	1,014	$	—

The following table summarizes the change in the estimated fair value of the Company’s outstanding warrant liabilities as of March 31, 2018:



Warrant Liabilities (In thousands)
Balance at December 31, 2017	$	1,014
Increase in fair value	2,907
Warrant exercise	(2,000		)
Balance at March 31, 2018	$	1,921

The increase in fair value of warrants is due to the increase in stock price which has a direct impact to the Black-Scholes valuation model discussed in note 6.

Revolving and Term Loan Credit Agreements

At each of March 31, 2018 and December 31, 2017, the Company had a total of $17.2 million net debt outstanding under our revolving and term loan credit agreements, which are variable rate loans. The fair value of these loans approximates book value based on the borrowing rates currently available for variable rate loans obtained from third party lending institutions. These fair values represent Level 2 under the three-tier hierarchy described above.
