Schedule of acquired intangible assets

The following table presents certain information on the acquired intangible assets (in thousands):

Intangible Assets	Fair Value		Estimated Useful Lives (Years)	Weighted-average Estimated Useful Lives (Years)	Discount Rate
GPX India:
Customer relationships (1)	$	15,472	15.0	15.0	11.0	%
Bell:
Customer relationships (1)	75,857		15.0	15.0	8.0	%
Packet:
Trade names (2)	1,300		3.0	3.0	8.0	%
Existing technology (3)	5,100		3.0	3.0	8.0	%
Customer relationships (1)	52,100		10.0	10.0	8.0	%
Axtel:
Customer relationships (1)	22,750		15.0	15.0	13.3	%

(1)The fair values were estimated by calculating the present value of estimated future operating cash flows generated from existing customers less costs to realize the revenue. The rates reflect the nature of the assets as they relate to the risk and uncertainty of the estimated future operating cash flows, as well as the risk of the country within which the acquired business operates.

(2)The fair value was estimated using the relief from royalty method, with a relief from royalty rate of 1.0%.

(3)The fair value was estimated under the cost approach by projecting the cost to recreate a new asset with an equivalent utility of the existing technology. The key assumptions include total cost, time to recreate, opportunity cost and functional obsolescence. The discount rate was utilized for the opportunity cost assumption.
