3.Business Acquisitions, Goodwill and Intangible Assets

The Company completed one acquisition during the year ended September 30, 2016 for total consideration of $5.5 million. The business combination did not meet the quantitative thresholds to require separate disclosures based on the Company’s consolidated net assets, investments and net income. The acquisition was accounted for under the purchase method of accounting. As such, the purchase consideration was allocated to acquired tangible and intangible assets and liabilities based upon their fair values. The determination of fair values of assets and liabilities acquired requires the Company to make estimates and use valuation techniques when market value is not readily available. Transaction costs associated with business acquisitions are expensed as they are incurred.

On October 17, 2014, the Company completed the acquisition of the U.S. headquartered URS Corporation (URS), an international provider of engineering, construction, and technical services, by purchasing 100% of the outstanding shares of URS common stock. The Company paid total consideration of approximately $2.3 billion in cash and issued approximately $1.6 billion of AECOM common stock to the former stockholders and certain equity award holders of URS. In connection with the acquisition, the Company also assumed URS’s senior notes totaling $0.4 billion, net of Company repayments. The Company repaid in full URS’s $0.6 billion 2011 term loan and $0.1 billion of URS’s revolving line of credit.

The Company acquired backlog and customer relationship intangible assets valued at $973.8 million representing the fair value of existing contracts and the underlying customer relationships, and have lives ranging from 1 to 11 years (weighted average lives of approximately 3 years) in connection with the URS acquisition. Acquired accrued expenses and other current liabilities include URS project liabilities and approximately $240 million related to estimated URS legal settlements and uninsured legal damages; see Note 14, Commitments and Contingencies, including legal matters related to former URS affiliates.

Amortization of intangible assets relating to URS, included in cost of revenue, was $20.9 million and $59.1 million during the three months ended March 31, 2017 and 2016, respectively, and $41.8 million and $118.1 million during the six months ended March 31, 2017 and 2016, respectively. Additionally, included in equity in earnings of joint ventures and noncontrolling interests was intangible amortization expense of $2.5 million and ($2.1) million, respectively, during the three months ended March 31, 2017 and $6.5 million and ($3.9) million, respectively, during the three months ended March 31, 2016 related to joint venture fair value adjustments.

Billings in excess of costs on uncompleted contracts includes a margin fair value liability associated with long-term contracts acquired in connection with the acquisition of URS. This margin fair value liability was $149.1 million at the acquisition date and its carrying value was $11.7 million at March 31, 2017, and is recognized as revenue on a percentage-of-completion basis as the applicable projects progress. The majority of this liability was recognized over the first two years from the acquisition date. Revenue and the related income from operations related to the margin fair value liability recognized during the three months ended March 31, 2017 and 2016 was $1.6 million and $13.2 million, respectively; revenue and the related income from operations related to the margin fair value liability recognized during the six months ended March 31, 2017 and 2016 was $3.2 million and $28.4 million, respectively.
