EXHIBIT 99.1

Report of Independent Registered Public Accounting Firm

The Board of Members
EGS Electrical Group, LLC:

        We have audited the accompanying consolidated balance sheets of EGS Electrical Group, LLC and subsidiaries (the Company) as of September 30, 2011 and 2010, and the related consolidated statements of income, members' equity and comprehensive income, and cash flows for each of the years in the three-year period ended September 30, 2011. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

        We conducted our audits in accordance with generally accepted auditing standards as established by the Auditing Standards Board (United States) and in accordance with the auditing standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

        In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of EGS Electrical Group, LLC and subsidiaries as of September 30, 2011 and 2010, and the results of their operations and their cash flows for each of the years in the three-year period ended September 30, 2011, in conformity with U.S. generally accepted accounting principles.
