The following table below summarizes the preliminary allocation of the tangible and identifiable intangible assets acquired and liabilities assumed as of October 31, 2013, as well as the adjustments made in the quarter ended March 31, 2014 (in thousands):

a. The Company finalized the working capital adjustment during the three months ended March 31, 2014, which led to a decrease of $2.4 million in receivables and a corresponding increase in cash. As a result of this adjustment, the total cash acquired from the acquisition also increased by the same amount. The net effect of this adjustment is an increase in goodwill of $2.4 million. b. The Company updated its preliminary estimate of the fair value of property and equipment which led to a decrease of $3.0 million in property and equipment with a corresponding increase in goodwill. The Company also updated the fair values of the asset retirement obligations and the related asset retirement assets which led to an increase in the fair value of property and equipment of $1.2 million and a corresponding increase in current liabilities and other long-term liabilities of $0.2 million and $1.0 million, respectively. The decrease in depreciation expense due to the change in fair value of property and equipment was immaterial for the quarter ended December 31, 2013. c. During the three months ended March 31, 2014, there were no changes to the fair value of the identifiable intangible assets acquired. However, the Company revised the estimated useful life of Order backlog from 1.5 years to 1 year, which would have increased the amortization expense for the three months ended December 31, 2013 by $0.8 million to a total of $4.6 million amortization expense upon retrospective adjustment for such change in estimate. d. The Company obtained new information regarding accruals for litigation and statutory tax assessment as of the acquisition date which led to an increase in the fair value of current liabilities of $0.7 million and a corresponding increase in goodwill. e. The Company obtained new information regarding the existence of accrued liabilities as of the acquisition date which led to an increase in the fair value of accrued liabilities by $0.5 million with a corresponding increase in goodwill. The change in the fair value measurement for such accrued liabilities would have decreased operating expenses for three months ended December 31, 2013 by $0.5 million.
