GOODWILL AND OTHER INTANGIBLE ASSETS
GOODWILL AND OTHER INTANGIBLE ASSETS
Goodwill and other identifiable indefinite lived intangibles are not amortized, but are subject to an annual impairment test, or more frequent testing if circumstances indicate that they may be impaired.
Goodwill:
We have two geographical reportable segments, “United States” and “International”, both of which have goodwill. The changes in the carrying amount of goodwill since January 1, 2013, by reportable segment, were as follows:

Current year adjustments to goodwill for certain 2013 acquisitions are primarily due to the finalization of intangible asset valuations.

Our finite-lived intangible assets are amortized over their useful lives. We have determined that our customer relationships have useful lives from 10 to 40 years based upon the type of customer, with a weighted average remaining useful life of 25.3 years. We have covenants not-to-compete intangibles with useful lives from 3 to 14 years, with a weighted average remaining useful life of 3.7 years. We have tradename intangibles with useful lives from 10 to 40 years, with a weighted average remaining useful life of 15.4 years. We have license agreements with useful life of 5 years, with a weighted average remaining useful life of 1.5 years. We have determined that our permits have indefinite lives due to our ability to renew these permits with minimal additional cost, and therefore these are not amortized.
During the quarters ended March 31, 2014 and 2013, the aggregate amortization expense was $7.3 million and $6.6 million, respectively.
The estimated amortization expense for each of the next five years, assuming no additional amortizable intangible assets, is as follows for the years ended December 31:

Future amortization expense may fluctuate depending on changes in foreign currency rates, future acquisitions, or changes to the estimated amortizable life of the intangibles. The estimates for amortization expense noted above are based upon foreign exchange rates as of March 31, 2014.
