Business Combination

On September 2, 2016, PTF acquired certain assets and assumed certain liabilities of Precise Time and Frequency, Inc. ("PTF Inc.") for cash consideration of $295,000 (the "PTF Acquisition"). The PTF Acquisition was accounted for under the acquisition method of accounting for business combinations pursuant to the provisions of ASC 805, Business Combinations. The acquisition method of accounting requires, among other things, that the assets acquired and liabilities assumed in a business combination be measured at their fair values as of the closing date of the acquisition.
