[1] The fair value of the acquired assets was estimated using the Income Approach with a discounted cash flow valuation methodology applied.

[2] During the second quarter of 2018 we recognized an impairment loss of $79,634 on the Promasys B.V. Customer List after performing a fair value analysis on the asset utilizing a discounted cash flow model. The impairment charge is separately presented on the Statement of Operations.

[3] The acquired Promasys B.V. software code and customer list are not measured on a recurring basis since their initial fair value has been deemed to have a finite life and is being amortized periodically. Instead, the Company performs an impairment analysis on a quarterly basis in order to determine whether the carrying value of the assets reflects the fair value of the assets in a market based transaction.

[4] The acquired Acuity software code is not measured on a recurring basis since the initial fair value has been deemed to have a finite life and is being amortized periodically. Instead, the Company performs an impairment analysis on a quarterly basis in order to determine whether the carrying value of the assets reflects the fair value of the assets in a market based transaction.
