2. Business Combinations

In the three months ended September 30, 2018, we acquired Mojo Networks, Inc. (“Mojo”) and Metamako Holding PTY LTD. (“Metamako”) in order to extend our cognitive cloud networking architecture and to improve our next generation platforms for low-latency applications.

The total consideration transferred for these acquisitions was approximately $116.5 million, which consisted of $100.9 million in cash and $15.6 million for the fair value of 58,072 shares of our common stock issued. The following table summarizes our preliminary purchase price allocation of the two acquisitions, in aggregate, based on the estimated fair value of the assets acquired and liabilities assumed at their respective acquisition dates (in thousands):



	Purchase Price Allocation
Cash and cash equivalents	$	4,953
Other tangible assets	22,445
Liabilities	(29,780		)
Intangible assets	63,720
Goodwill	55,168
Net assets acquired	$	116,506

The acquired intangible assets are amortized on a straight-line basis over their estimated useful lives as we believe this method most closely reflects the pattern in which the economic benefits of the assets will be consumed. The following table shows the valuation of the intangible assets acquired (in thousands) along with their estimated useful lives.



	Acquisition Date Fair Value		Estimated Useful Life (year)
Developed technology	$	52,510	5 years
Customer relationships	7,080		7 years
Trade name	2,470		3 years
Others	1,660		1 year
Total intangible assets acquired	$	63,720

The goodwill of $55.2 million is primarily attributable to the expected synergies created by incorporating the solutions of the acquired businesses into our technology platform, and the value of the assembled workforce. We operate under a single reportable segment. The goodwill is not deductible for income taxes purposes.

For the three and nine months ended September 30, 2018, revenue and earnings from the acquired businesses included in our condensed consolidated statements of operations were immaterial. Pro forma results of operations for these acquisitions have not been presented because they are not material to the consolidated results of operations, either individually or in aggregate.
