NOTE 7 - FAIR VALUE MEASURMENT

 

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 June 30, 2017 and December 31, 2016, allowance for doubtful accounts was $70,000 and $336,000, respectively, with the decrease resulting primarily from bad debt write offs.
