The table below presents the provisional estimated fair value of assets acquired and liabilities assumed on the acquisition date based on the best information it has received to date, in accordance with ASC 805. The Company is awaiting final appraisal of tangible assets, intangible assets and certain contingent liabilities related to the GPECS acquisition. Accordingly, the Company has adjusted the value of intangible assets, property and equipment and contingent liabilities to draft appraisals. During the six months ended September 30, 2013, the Company recognized an increase of $29,511 in the provisional value of intangible assets as a result of the recognition of a definite-lived technology intangible asset and changes in the fair value of customer relationships acquired.
