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 three months ended June 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. Additionally, the Company recognized other immaterial adjustments to various assets acquired and liabilities assumed as of the acquisition date. These purchase price adjustments decreased the provisionally recognized goodwill by $27,963 and have been reflected retrospectively as of March 31, 2013 in the accompanying Consolidated Balance Sheet. The effect on net income for the period March 18, 2013 through March 31, 2013 was not material. Therefore, the allocation of the purchase price of the GPECS acquisition is not complete and the amounts below report the Company's best estimate of the fair value based on the information available at this time:
