There have been no changes in the Company’s significant accounting policies from those that were disclosed in the Company’s 2013 Annual Report. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Key estimates for the Company include: the recognition of revenue, in particular, estimated losses on long term construction contracts, allowance for doubtful accounts; inventory valuation; asset lives used in computing depreciation and amortization; valuation of intangible assets; valuation of contingent consideration; allowance for self-insurance health care claims incurred but not reported; accounting for stock options and other equity awards, particularly related to fair value estimates; accounting for income taxes; contingencies; and litigation. While management believes that such estimates are reasonable when considered in conjunction with the financial position and results of operations taken as a whole, actual results could differ from those estimates, and such differences may be material to the consolidated financial statements. Revenue Recognition The Company recognizes revenue when: (i) persuasive evidence of a customer arrangement exists; (ii) the price is fixed or determinable; (iii) collectability is reasonably assured and (iv) product delivery has occurred or services have been rendered. The Company recognizes revenue as services are performed and completed. The Company enters into contracts that require the construction and/or installation of specific units within a network system. Revenue from construction and installation contracts is recorded using the completed contract method of accounting. Under the completed contract method, revenues and costs from construction and installation projects are recognized only upon substantial completion of the project. Project costs typically include direct materials, labor and subcontractor costs, and indirect costs related to contract performance, such as indirect labor, supplies, and tools. Provisions for estimated losses on uncompleted contracts are recognized when it has been determined that a loss is probable. The Company also enters into contracts to provide engineering and integration services related to network architecture, transformation, reliability and performance. Revenues and costs from service contracts are generally recognized at the time the services are completed under the completed performance model. Services are generally performed under master or other services agreements and are billed on a contractually agreed price per unit of service on a work order basis. Services invoiced prior to the performance of the obligation are recorded in deferred revenue and recognized as the services are performed. The total amount of progress payments netted against contract costs on uncompleted contracts as of December 31, 2013 and June 30, 2014 was $197.9 million and $226.6 million, respectively.

The amendments in ASU 2014-08 change the criteria for reporting discontinued operations while enhancing disclosures in this area.

ASU 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for the Company on January 1, 2017.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in all material respects in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information. Pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”), certain information and footnote disclosures normally included in the annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. The accompanying unaudited consolidated financial statements have been prepared on the same basis as the financial statements for the year ended December 31, 2013.

Because certain information and footnote disclosures have been condensed or omitted, these unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto as of and for the year ended December 31, 2013, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013 (the “2013 Annual Report”).

There have been no changes in the Company’s significant accounting policies from those that were disclosed in the Company’s 2013 Annual Report.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes.
