On February 9, 2012, we completed a reverse merger transaction through a merger with GrowOp Technology, whereby we acquired all of the issued and outstanding shares of GrowOp Technology and in exchange we issued: (i) 33,998,520 shares of our common stock, (ii) 100 shares of Series A Preferred Stock, convertible into shares of common stock on a one-for-one basis, and (iii) 14,750,000 shares of Series B Preferred Stock, with each share convertible into 5.38425537 shares of common stock. As a result of the reverse merger, GrowOp Technology became our wholly-owned subsidiary and, at the time the transaction was closed, the former stockholders of GrowOp Technology became our controlling stockholders. The share exchange transaction with GrowOp Technology was treated as a reverse acquisition, with GrowOp Technology as the accounting acquiror and the Company as the accounting acquiree.

Purchase Accounting

The acquisition was accounted for using the purchase method of accounting as a reverse acquisition. In a reverse acquisition, the post-acquisition net assets of the surviving combined company include the historical cost basis of the net assets of the accounting acquirer, GrowOp Technologies, plus the fair value of the net assets of the accounting acquiree, Terra Tech. Further, under the purchase method, the purchase price is allocated to the assets acquired and liabilities assumed based on their estimated fair values and the excess of the purchase price over the estimated fair value of the identifiable net assets is allocated to any intangible assets with the remaining excess purchase price over net assets acquired allocated to goodwill.

The fair value of the consideration transferred in the acquisition was $4,800,000 and was calculated as the number of shares of common stock that GrowOp Technologies would have had to issue in order for Terra Tech stockholders to hold a 58.6% equity interest in the combined company post-acquisition, multiplied by the estimated fair value of our common stock on the acquisition date. The estimated fair value of our common stock was based on the offering price of the common stock sold in a private placement of share subscriptions which was completed most recently prior to the merger. This price was determined to be the best indication of fair value on that date since the price was based on an arm's length negotiation with a group consisting of both new and existing investors that had been advised of the pending acquisition and assumed similar liquidity risk as those investors holding the majority of shares being valued as purchase consideration.

The following table summarizes our determination of fair values of the assets acquired and the liabilities as of the date of acquisition.

We performed an impairment test related to goodwill as of the date of the merger and it was determined that goodwill was impaired. At that time, we recorded a charge to operations for the amount of the impairment, which totaled $4,799,965.
