Goodwill and Intangible Assets

Goodwill

The Company's goodwill balance was $271.7 million and $269.1 million as of July 25, 2015 and July 26, 2014, respectively. The increase in goodwill during fiscal 2015 was primarily the result of preliminary purchase price allocations associated with businesses acquired in fiscal 2015. Changes in the carrying amount of goodwill for fiscal 2015 and fiscal 2014 were as follows:



	Goodwill		Accumulated Impairment Losses			Total
	(Dollars in thousands)
Balance as of July 27, 2013	$	463,577	$	(195,767	)	$	267,810
Goodwill from fiscal 2014 acquisitions	1,278		—			1,278
Balance as of July 26, 2014	464,855		(195,767		)	269,088
Purchase price allocation adjustments	377		—			377
Goodwill from fiscal 2015 acquisitions	2,188		—			2,188
Balance as of July 25, 2015	$	467,420	$	(195,767	)	$	271,653

The Company's goodwill resides in multiple reporting units. Goodwill and other indefinite-lived intangible assets are assessed annually for impairment as of the first day of the fourth fiscal quarter of each year, or more frequently if events occur that would indicate a potential reduction in the fair value of a reporting unit below its carrying value. The profitability of individual reporting units may suffer periodically due to downturns in customer demand and the level of overall economic activity, including in particular construction and housing activity. The Company's customers may reduce capital expenditures and defer or cancel pending projects during times of slowing economic conditions. Additionally, adverse conditions in the economy and future volatility in the equity and credit markets could impact the valuation of the Company's reporting units. The cyclical nature of the Company's business, the high level of competition existing within its industry, and the concentration of its revenues from a limited number of customers may also cause results to vary. These factors may affect individual reporting units disproportionately, relative to the Company as a whole. As a result, the performance of one or more of the reporting units could decline, resulting in an impairment of goodwill or intangible assets.

The Company evaluates current operating results, including any losses, in the assessment of goodwill and other intangible assets. The estimates and assumptions used in assessing the fair value of the reporting units and the valuation of the underlying assets and liabilities are inherently subject to significant uncertainties. Changes in judgments and estimates could result in a significantly different estimate of the fair value of the reporting units and could result in impairments of goodwill or intangible assets of the reporting units. In addition, adverse changes to the key valuation assumptions contributing to the fair value of the Company's reporting units could result in an impairment of goodwill or intangible assets.

The Company performed its annual impairment assessment as of the first day of the fourth quarter of each of fiscal 2015, 2014, and 2013 and concluded that no impairment of goodwill or the indefinite-lived intangible asset was indicated at any reporting unit for any of the years. During fiscal 2015, the Company performed qualitative assessments on reporting units that comprise a substantial portion of its consolidated goodwill balance and on its indefinite-lived intangible asset. A qualitative assessment includes evaluating all identified events and circumstances that could affect the significant inputs used to determine the fair value of a reporting unit or indefinite-lived intangible asset for the purpose of determining whether it is more likely than not that these assets are impaired. The Company considers various factors while performing qualitative assessments, including macroeconomic conditions, industry and market conditions, financial performance of the reporting units, changes in market capitalization, and any other specific reporting unit considerations. These qualitative assessments indicated that it was more likely than not that the fair value exceeded carrying value for those reporting units. For the remaining reporting units, the Company performed the first step of the quantitative analysis described in ASC Topic 350. Under the income approach, the key valuation assumptions used in determining the fair value estimates of the Company's reporting units for each annual test were (a) a discount rate based on the Company's best estimate of the weighted average cost of capital adjusted for certain risks for the reporting units; (b) terminal value based on terminal growth rates; and (c) seven expected years of cash flow before the terminal value. The table below outlines certain assumptions in each of the Company's fiscal 2015, 2014, and 2013 annual quantitative impairment analyses:



	2015	2014	2013
Terminal Growth Rate Range	1.5% - 2.5%	1.5% - 3.0%	1.5% - 2.5%
Discount Rate	11.5%	11.5%	11.5%

The discount rate reflects risks inherent within each reporting unit operating individually, which are greater than the risks inherent in the Company as a whole. The fiscal 2015, 2014, and 2013 analyses used the same discount rate given a consistent assessment of risk relative to industry conditions and an unchanged interest rate environment. The Company believes the assumptions used in the impairment analysis each year are reflective of the risks inherent in the business models of its reporting units and within its industry. Under the market approach, the guideline company method develops valuation multiples by comparing the Company's reporting units to similar publicly traded companies. Key valuation assumptions and valuation multiples used in determining the fair value estimates of the Company's reporting units rely on (a) the selection of similar companies; (b) obtaining estimates of forecast revenue and earnings before interest, taxes, depreciation, and amortization for the similar companies; and (c) selection of valuation multiples as they apply to the reporting unit characteristics.

The Company determined that the fair values of each of the reporting units was substantially in excess of their carrying values in the fiscal 2015 annual assessment. Management determined that significant changes were not likely in the factors considered to estimate fair value and analyzed the impact of such changes were they to occur. Specifically, if there was a 25% decrease in the fair value of any of the reporting units due to a decline in their discounted cash flows resulting from lower operating performance, the conclusion of the assessment would not change. Additionally, if the discount rate applied in the fiscal 2015 impairment analysis had been 100 basis points higher than estimated for each of the reporting units, and all other assumptions were held constant, the conclusion of the assessment would remain unchanged and there would be no impairment of goodwill. As of July 25, 2015, the Company believes the goodwill is recoverable for all of the reporting units; however, there can be no assurances that the goodwill will not be impaired in future periods.

Intangible Assets

The Company's intangible assets consisted of the following:



	Weighted Average Remaining Useful Lives	July 25, 2015		July 26, 2014
	(Years)	(Dollars in thousands)
Gross carrying amount:
Customer relationships	11.6	$	195,375	$	173,594
Contract backlog	2.4	8,076		15,285
Trade names	3.4	8,200		8,200
UtiliQuest trade name	—	4,700		4,700
Non-compete agreements	2.2	635		400
		216,986		202,179
Accumulated amortization:
Customer relationships		83,772		69,048
Contract backlog		7,381		13,490
Trade names		4,650		3,361
Non-compete agreements		257		164
		96,060		86,063
Net Intangible Assets		$	120,926	$	116,116

During fiscal 2015, the gross carrying amount of customer relationships and non-compete agreements intangible assets increased $21.8 million and $0.2 million, respectively, for businesses acquired during fiscal 2015. During fiscal 2015, certain contract backlog intangible assets became fully amortized. As a result, the gross carrying amount and the associated accumulated amortization decreased $7.2 million. This decrease had no effect on the net carrying value of intangible assets as of July 25, 2015.

Amortization of the Company's customer relationship intangibles and the contract backlog intangibles acquired in fiscal 2013 is recognized on an accelerated basis as a function of the expected economic benefit. Amortization for the Company's other finite-lived intangibles is recognized on a straight-line basis over the estimated useful life. Amortization expense for finite-lived intangible assets was $16.7 million, $18.3 million, and $20.7 million for fiscal 2015, 2014, and 2013, respectively.

Estimated total amortization expense for existing intangible assets for each of the five succeeding fiscal years and thereafter is as follows:



Period	Amount
	(Dollars in thousands)
2016	$	17,315
2017	15,788
2018	13,494
2019	11,142
2020	10,230
Thereafter	48,257
Total	$	116,226

As of July 25, 2015, the Company believes that the carrying amounts of its intangible assets are recoverable. However, if adverse events were to occur or circumstances were to change indicating that the carrying amount of such assets may not be fully recoverable, the assets would be reviewed for impairment and the assets could be impaired.
