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 shares 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, respectively. Regarding the value as of June 2018 see Note 3i.

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 June 30, 2018, and December 31, 2017, allowance for doubtful accounts was $72,000.
