Goodwill and Intangible Assets Disclosure [Abstract]

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.

We have two geographical reporting segments, “United States” and “International”, both of which have goodwill. The changes in the carrying amount of goodwill since December 31, 2011, by reportable segment, were as follows:

	United States			International			Total
Balance as of December 31, 2011	$	1,506,416		$	407,287		$	1,913,703

Balance as of June 30, 2013	$	1,632,717		$	461,742		$	2,094,459

Current year adjustments to goodwill for certain 2012 acquisitions are primarily due to the finalization of intangible asset valuations.

During the quarter ended June 30, 2013, we performed our annual goodwill impairment evaluation for our three reporting units, Domestic Regulated Waste, Domestic Regulated Recall and Returns Management Services, and International. We calculated fair value for our reporting units using two methods, one a market approach and the other an income approach. Both the market and income approaches indicated no impairment to goodwill to any of our three reporting units.

Market Approach: Our market approach begins by calculating the market capitalization of the Company using the average stock price for the prior twelve months and the outstanding share count at June 30, 2013. We then look at the Company's Earnings Before Interest, Tax, Depreciation, and Amortization (“EBITDA”), adjusted for stock compensation expense and other items, such as change in fair value of contingent consideration, restructuring and plant closure costs, and litigation settlement for the prior twelve months. The calculated market capitalization is divided by the modified EBITDA to arrive at a valuation multiple. The fair value of each reporting unit is then calculated by taking the product of the valuation multiple and the trailing twelve month modified EBITDA of that reporting unit. The fair value was then compared to the reporting units' book value and determined to be in excess of the book value. We believe that starting with the fair value of the company as a whole is a reasonable measure as that fair value is then allocated to each reporting unit based on that reporting unit's individual earnings. A sustained drop in our stock price would have a negative impact to our fair value calculations. A temporary drop in earnings of a reporting unit would have a negative impact to our fair value calculations.

The results of our goodwill impairment test using the market approach indicated the fair value of our reporting units exceeded book value by a substantial amount, in excess of 100% of book value.

Income Approach: The income approach uses expected future cash flows of each reporting unit and discounts those cash flows to present values. Expected future cash flows are calculated using management assumptions of internal growth, capital expenditures, and cost efficiencies. Future acquisitions are not included in the expected future cash flows. We use a discount rate based on our Company calculated weighted average cost of capital which is adjusted for each of our reporting units based on size risk premium and country risk premium. Significant assumptions used in the income approach include realization of future cash flows and the discount rate used to present value those cash flows.

The results of our goodwill impairment test using the income approach indicated the fair value of our reporting units exceeded book value by a substantial amount; in excess of 100% .

We perform our annual impairment analysis of our indefinite lived intangibles (facility permits) during the quarter ended December 31 of each year.

Other intangible assets, other than indefinite lived goodwill and permits, are amortized over their useful lives. We have determined that our customer relationships have useful lives from 14 to 40 years based upon the type of customer, with a weighted average remaining useful life of 26.1 years. We have covenants not-to-compete intangibles with useful lives from 5 to 14 years, with a weighted average remaining useful life of 4.3 years. We have tradename intangibles with useful lives from 10 to 40 years, with a weighted average remaining useful life of 16.2 years. We have license agreements with useful life of 5 years, with a weighted average remaining useful life of 2.4 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.

As of June 30, 2013 and December 31, 2012, the values of the intangible assets were as follows:

During the quarters ended June 30, 2013 and 2012, the aggregate amortization expense was $6.5 million and $5.1 million, respectively. For six months ended June 30, 2013 and 2012, the aggregate amortization expense was $13.2 million and $10.1 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:

2013	$	26,132
2014	26,369
2015	26,084
2016	25,939
2017	25,789

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 June 30, 2013.
