(“Solais”), EnergyLite, Inc.(“EnergyLite”), EfficientLights, LLC (“EfficientLights”), Innovative Electronic Solutions Lighting, LLC (“IES”), Reid’s Trailer, Inc. d/b/a PowerFab (“PowerFab”), Innovation Energies, LLC, and PowerSecure Solar, LLC (“PowerSecure Solar”) and PowerPackages, LLC which are collectively referred to as the “Company” or “PowerSecure” or “we” or “us” or “our”. On June 30, 2014, EfficientLights and IES were dissolved and merged into EnergyLite. These condensed consolidated financial statements have been prepared pursuant to rules and regulations of the Securities and Exchange Commission. The accompanying condensed consolidated financial statements and notes thereto should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2014. In management’s opinion, all adjustments (all of which are normal and recurring) have been made which are necessary for a fair presentation of the condensed consolidated financial position of us and our subsidiaries as of June 30, 2015 and the condensed consolidated results of our operations and cash flows for the three and six months ended June 30, 2015 and 2014.
Principles Of Consolidation	Principles of Consolidation – The condensed consolidated financial statements include the accounts of PowerSecure International, Inc. and its subsidiaries after elimination of intercompany accounts and transactions.
Comprehensive Income Or Loss	Comprehensive Income or Loss – Comprehensive income or loss represents the changes in stockholders’ equity during a period resulting from transactions and other events and circumstances from non-owner sources. At June 30, 2015 and December 31, 2014, the balance of Accumulated other comprehensive income (loss) (“Accumulated OCI”) consisted solely of changes in the fair value of our interest rate cash flow hedge contracts, net of taxes.
Use Of Estimates	Use of Estimates – The preparation of our consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires that our management make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates include, among others, percentage-of-completion estimates for revenue and cost of sales recognition, incentive compensation and commissions, allowance for doubtful accounts receivable, inventory valuation reserves, warranty reserves, deferred tax valuation allowance, purchase price allocations on business acquisitions, fair value estimates of interest rate swap contracts and any impairment charges on long-lived assets and goodwill.
Reclassifications	Reclassifications – Certain 2014 amounts have been reclassified to conform to current year presentation. Such reclassifications had no effect on net income (loss) or stockholders’ equity as previously reported.
