Fair Value Measurement

NOTE 5 - FAIR VALUE MEASURMENT:

The following tables summarize the activity for those financial liabilities where fair value measurements are estimated utilizing Level 3 inputs:

	Derivative liability
Balance as of January 1, 2018	$	-
Classification of Redemption Obligation of preferred shares holder to Mezzanine		620
Revaluation of embedded derivative- financial expenses		433
Conversion of Series C Preferred Stock to common shares		(181	)
Balance as of March 31, 2018	$	872

Level 3 liabilities include Derivative Liability related to the Company Series C Preferred Stock, as described in Note 3c. The Company values the Level 3 Derivative Liability using multi-period binomial model, whose inputs include probability of completing fund raising and the related fund raise amounts, volatility of stock prices, stock prices, term to extinguish the Series C Preferred Stock held by the Series D Investor.

In calculating the fair value of Derivative Liability, the Company used the following assumptions: stock price of $4.20 and $1.04 for the transaction date and for March 31, 2018, respectively and Volatility of 140.95% -166.60% and 152.92-200.35% for the transaction date and for March 31, 2018, respectively.

Fair value of financial instruments

The carrying amounts of financial instruments included in working capital approximate their fair value either because these amounts are presented at fair value or due to the relatively short-term maturities of such instruments.

As of both March 31, 2018, and December 31, 2017, allowance for doubtful accounts was $72,000.
