Management reviewed property and equipment for impairment as of June 30, 2016 and determined that the carrying amount of property and equipment related to the Kreider 1 project exceeded its estimated future undiscounted cash flows based on certain assumptions regarding timing, level and probability of revenues from sales of nutrient reduction credits and potentially needed capital expenditures and it was also determined that the salvage value of the system components will be offset by contractual decommissioning obligations. Kreider 1 was measured at estimated fair value on a non-recurring basis using level 3 inputs, which resulted in an impairment of $1,684,562 of the property and equipment for the year ended June 30, 2016. As of June 30, 2016, the net book value of Kreider 1 was zero. As of September 30, 2016, management believes that no additional impairment exists.

Depreciation expense was $502 and $75,879 for the three months ended September 30, 2016 and 2015, respectively.
