Sales Returns

If these returns had been fully processed, the allowance for sales returns balance would have been approximately $0.2 million and $0.4 million on June 30, 2017 and December 31, 2016, respectively. The value of these returned goods was included in our inventory balance at June 30, 2017 and December 31, 2016.
