Goodwill and Intangible Assets Disclosure [Abstract] |
Goodwill and Intangible Assets | Goodwill and Intangible Assets Goodwill The Company's goodwill balance was $269.5 million and $269.1 million as of April 25, 2015 and July 26, 2014, respectively. The increase in goodwill during fiscal 2015 is the result of preliminary purchase price allocations and final working capital adjustments associated with businesses acquired in fiscal 2014. Changes in the carrying amount of goodwill for fiscal 2015 were as follows:
| Goodwill |  | Accumulated Impairment Losses |  | Total
| (Dollars in thousands)
Balance as of July 26, 2014 | $ | 464,855 |  |  | $ | (195,767 | ) |  | $ | 269,088 |
Purchase price allocation adjustments | 377 |  |  | — |  |  | 377 |
Balance as of April 25, 2015 | $ | 465,232 |  |  | $ | (195,767 | ) |  | $ | 269,465 |
The Company's 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 Company's goodwill resides in multiple reporting units. The profitability of individual reporting units may suffer periodically from downturns in customer demand and other factors resulting from the cyclical nature of the Company's business, the high level of competition existing within the Company's industry, the concentration of the Company's revenues from a limited number of customers, and the level of overall economic activity, including in particular construction and housing activity. During times of slowing economic conditions, the Company's customers may reduce capital expenditures and defer or cancel pending projects. Individual reporting units may be more impacted by these factors than the Company as a whole. As a result, the performance of the Company's reporting units could decline, resulting in an impairment of goodwill or intangible assets. As a result of the fiscal 2014 annual impairment analysis, the Company concluded that no impairment of goodwill or the indefinite-lived intangible asset was indicated at any reporting unit. During fiscal 2014, qualitative assessments were performed by the Company as the primary assessment method on reporting units comprising less than 20% of its consolidated goodwill balance. The qualitative assessments indicated that it was more likely than not that 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, Intangibles-Goodwill and Other. The key valuation assumptions used in determining the fair value estimates of the Company's reporting units were (a) a discount rate of 11.5% based on the Company's best estimate of the weighted average cost of capital adjusted for risks associated with the reporting units; (b) terminal value based on terminal growth rates ranging from 1.5% to 3.0%; and (c) seven expected years of cash flow before the terminal value for each annual test. In the fiscal 2014 impairment analysis, the fair value for three of the reporting units acquired in fiscal 2013 exceeded their carrying value by less than 25% each. The goodwill balances for these reporting units were $10.6 million, $4.8 million and $3.6 million. Recent operating performance, along with assumptions for specific customer and industry opportunities, were considered in the key assumptions used during the fiscal 2014 impairment analysis. Management has determined that the goodwill balance of these reporting units may have an increased likelihood of impairment if the long-term outlook for their cash flows were adversely impacted by a prolonged downturn in customer demand or if the reporting units were not able to execute against customer opportunities. Furthermore, changes in the long-term outlook may result in changes to other valuation assumptions. Factors monitored by management which could result in a change to the reporting units' estimates include the outcome of customer requests for proposals and subsequent awards, strategies of competitors, labor market conditions and levels of overall economic activity, including construction and housing activity. As of April 25, 2015, the Company believes the goodwill is recoverable for all of the reporting units; however, there can be no assurances that goodwill will not be impaired in future periods. Intangible Assets The Company's intangible assets consisted of the following:
| April 25, 2015 |  | July 26, 2014
| (Dollars in thousands)
Carrying amount: |  |  |
Customer relationships | $ | 179,859 |  |  | $ | 173,594 |
Contract backlog | 8,076 |  |  | 15,285 |
Trade names | 8,200 |  |  | 8,200 |
UtiliQuest trade name | 4,700 |  |  | 4,700 |
Non-compete agreements | 400 |  |  | 400 |
| 201,235 |  |  | 202,179 |
Accumulated amortization: |  |  |  |  |
Customer relationships | 79,531 |  |  | 69,048 |
Contract backlog | 7,121 |  |  | 13,490 |
Trade names | 4,328 |  |  | 3,361 |
Non-compete agreements | 224 |  |  | 164 |
| 91,204 |  |  | 86,063 |
Net Intangible Assets | $ | 110,031 |  |  | $ | 116,116 |
During fiscal 2015, the carrying amount of customer relationship intangible assets increased $5.9 million as a result of the preliminary purchase price allocation for Hewitt and $0.4 million as a result of the preliminary purchase price allocation for businesses acquired during the second quarter of fiscal 2015. The carrying amount of contract backlog and the associated accumulated amortization decreased $7.2 million during fiscal 2015 as the intangible assets became fully amortized. This decrease did not impact the net carrying value of intangible assets as of April 25, 2015. Amortization of the Company's customer relationships and contract backlog intangible assets 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 of the intangible asset. Amortization expense for finite-lived intangible assets was $4.1 million for each of the three months ended April 25, 2015 and April 26, 2014, and $12.4 million and $14.1 million for the nine months ended April 25, 2015 and April 26, 2014, respectively. Estimated total amortization expense for existing intangible assets for the remainder of fiscal 2015 and each of the five succeeding fiscal years and thereafter is as follows (dollars in thousands):
Period |  | Amount
Three months ending July 25, 2015 |  | $ | 4,147 |
2016 |  | 15,918 |
2017 |  | 14,403 |
2018 |  | 12,212 |
2019 |  | 9,792 |
2020 |  | 8,855 |
Thereafter |  | 40,004 |
Total |  | $ | 105,331 |
As of April 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.
