NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The Company’s accompanying consolidated financial statements include its wholly-owned subsidiary World Energy Securities Corp. All intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Accordingly, actual results could differ from these estimates.

The Company’s most judgmental estimates affecting its accompanying consolidated financial statements are those relating to revenue recognition and the estimate of actual energy delivered from the bidder to the lister of such energy; stock-based compensation; the valuation of intangible assets and goodwill; the valuation of contingent consideration; impairment of long-lived assets; warranty liability; and estimates of future taxable income as it relates to the realization of the Company’s net deferred tax assets. The Company regularly evaluates its estimates and assumptions based upon historical experience and various other factors that the Company believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. To the extent actual results differ from those estimates; future results of operations may be affected.

Revenue Recognition

Retail Electricity Transactions

The Company earns a monthly commission on energy sales contracted through its online auction platform from each bidder or energy supplier based on the energy usage transacted between the bidder and lister or energy consumer. The Company’s commissions are not based on the retail price for electricity; rather on the amount of energy consumed. Commissions are calculated based on the energy usage transacted between the energy supplier and energy consumer multiplied by the Company’s contractual commission rate. The contractual commission rate is negotiated with the energy consumer on a procurement-by-procurement basis based on energy consumer specific circumstances, including the size of auction, the effort required to organize and run the respective auction and competitive factors, among others. Revenue from commissions is recognized as earned on a monthly basis over the life of each contract as energy is consumed, provided there is persuasive evidence of an arrangement, the sales price is fixed or determinable, collection of the related receivable is reasonably assured, and customer acceptance criteria, if any, has been successfully demonstrated.

The Company records brokerage commissions based on actual usage data obtained from the energy supplier for that accounting period, or to the extent actual usage data is not available, based on the estimated amount of electricity and gas delivered to the energy consumers for that accounting period. The Company develops its estimates on a quarterly basis based on the following criteria:

Payments received prior to the issuance of the consolidated financial statements;

Usage updates from energy suppliers;

Usage data from utilities;

Comparable historical usage data; and

Historical variances to previous estimates.

To the extent usage data cannot be obtained, the Company estimates revenue as follows:

Historical usage data obtained from the energy consumer in conjunction with the execution of the auction;

Geographic/utility usage patterns based on actual data received;

Analysis of prior year usage patterns; and

Specific review of individual energy supplier/location accounts.

In addition, the Company analyzes this estimated data based on overall industry trends including prevailing weather and usage data. Once the actual data is received, the Company adjusts the estimated accounts receivable and revenue to the actual total amount in the period during which the payment is received. Based on management’s current capacity to obtain actual energy usage, the Company currently estimates four to six weeks of revenue at the end of its accounting period. Differences between estimated and actual revenue have been within management’s expectations and have not been material to date.

The Company does not invoice its electricity energy suppliers for monthly commissions earned and, therefore, it classifies a substantial portion of its receivables as “unbilled.” Unbilled accounts receivable represents management’s best estimate of energy provided by the energy suppliers to the energy consumers for a specific completed time period at contracted commission rates and is made up of two components. The first component represents energy usage for which the Company has received actual data from the supplier and/or the utility but for which payment has not been received at the balance sheet date. The majority of the Company’s contractual relationships with energy suppliers require them to supply actual usage data to the Company on a monthly basis and remit payment to the Company based on that usage. The second component represents energy usage for which the Company has not received actual data, but for which it has estimated usage. Commissions paid in advance by certain energy suppliers are recorded as deferred revenue and amortized to commission revenue on a monthly basis on the energy exchanged that month.

Retail Natural Gas Transactions

There are two primary fee components to the Company’s retail natural gas services: transaction fees and management fees. Transaction fees are billed to and paid by the energy supplier awarded business on the platform. These fees are established prior to award and are the same for each supplier. For the majority of the Company’s natural gas transactions, the supplier is billed upon the conclusion of the transaction based on the estimated energy volume transacted for the entire award term multiplied by the transaction fee. Management fees are paid by the Company’s energy consumers and are generally billed on a monthly basis for services rendered based on terms and conditions included in contractual arrangements. While substantially all of the Company’s retail natural gas transactions are accounted for in accordance with this policy, a significant percentage are accounted for as the natural gas is consumed by the customer and recognized as revenue in accordance with the retail electricity transaction revenue recognition methodology described above.

Mid-Market Transactions

The Company earns a monthly commission on energy sales from each energy supplier based on the energy usage transacted between the energy supplier and energy consumer. The commissions are not based on the retail price for electricity but rather on the amount of energy consumed. Commissions are calculated based on the energy usage transacted between the energy supplier and energy consumer multiplied by the Company’s contractual commission rate. Revenue from commissions is recognized as earned over the life of each contract as energy is consumed, provided there is persuasive evidence of an arrangement, the sales price is fixed or determinable, collection of the fee is reasonably assured, and customer acceptance criteria, if any, has been successfully demonstrated. The Company generally recognizes revenue on these transactions when it has received verification from the electricity supplier of the end-users power usage and electricity supplier’s subsequent collection of the fees billed to the end user. The verification is generally accompanied with payment of the agreed upon fee to the Company, at which time the revenue is recognized. Commissions paid in advance are recorded as customer advances and are recognized monthly as commission revenue based on the energy exchanged that month. To the extent the Company does not receive verification of actual energy usage or it cannot reliably estimate what actual energy usage was for a given period, revenue is deferred until usage and collection data is received from the energy supplier. To the extent that the Company does not receive actual usage data from the energy supplier, it will recognize revenue at the end of the contract flow date. In October 2012, the Company acquired Northeast Energy Partners, LP (“NEP”). NEP recognizes revenue monthly as energy flows from the energy supplier to the end user. The Company can reliably estimate actual energy usage based on historical usage data compiled by NEP.

Demand Response Transactions

Demand response transaction fees are recognized when the Company receives confirmation from the demand response provider (“DRP”) that the energy consumer has performed under the applicable Regional Transmission Organization (“RTO”) or Independent Service Operator (“ISO”) program requirements. The energy consumer is either called to perform during an actual curtailment event or is required to demonstrate its ability to perform in a test event during the performance period. For PJM Interconnection (“PJM”), an RTO that coordinates the movement of wholesale electricity in all or parts of 13 states and the District of Columbia, the performance period is June through September in a calendar year. Test results are submitted to PJM by the DRPs and the Company receives confirmation of the energy consumer’s performance in the fourth quarter. DRPs typically pay the Company ratably on a quarterly basis throughout the demand response fiscal (June to May) year. As a result, a portion of the revenue the Company recognizes is reflected as unbilled accounts receivable.

Wholesale and Environmental Commodity Transactions

Wholesale transaction fees are invoiced upon the conclusion of the auction based on a fixed fee. These revenues are not tied to future energy usage and are recognized upon the completion of the online auction. For reverse auctions where the Company’s customers bid for a consumer’s business, the fees are paid by the bidder. For forward auctions where a lister is selling energy products, the fees are typically paid by the lister. While substantially all wholesale transactions are accounted for in this fashion, a small percentage of the Company’s wholesale revenue is accounted for as electricity or gas is delivered, similar to the retail electricity transaction methodology described above.

Environmental commodity transaction fees are accounted for utilizing two primary methods. For regulated allowance programs like the Regional Greenhouse Gas Initiative (“RGGI”), fees are paid by the lister and are recognized as revenue quarterly as auctions are completed and approved. For most other environmental commodity transactions both the lister and the bidder pay the transaction fee and revenue is recognized upon the consummation of the underlying transaction as credits are delivered by the lister and payment is made by the bidder.

Channel Partner Commissions

The Company pays commissions to its channel partners at contractual rates based on monthly energy transactions between energy suppliers and energy consumers. The commission is accrued monthly and charged to sales and marketing expense as revenue is recognized. The Company pays commissions to its salespeople at contractual commission rates based upon cash collections from its customers.

Revenue Estimation

The Company’s estimates in relation to revenue recognition affect revenue and sales and marketing expense as reflected on its consolidated statements of operations, and trade accounts receivable and accrued commission accounts as reflected on its consolidated balance sheets. For any quarterly reporting period, the Company may not have actual usage data for certain energy suppliers and will need to estimate revenue. Revenue is initially recorded based on the energy consumers’ historical usage profile. At the end of each reporting period, the Company adjusts this historical profile to reflect actual usage for the period and estimate usage where actual usage is not available. For the year ended December 31, 2013, the Company estimated usage for approximately 9% of its revenue resulting in a negative 0.3%, or approximately $105,000, adjustment to decrease revenue. This decrease in revenue resulted in an approximate $16,000 decrease in sales and marketing expense related to third party commission expense associated with those revenues. Corresponding adjustments were made to trade accounts receivable and accrued commissions, respectively. A 1% difference between this estimate and actual usage would have an approximate $32,000 effect on the Company’s revenue for the year ended December 31, 2013.

Energy Efficiency Services

The Company’s Energy efficiency services segment is primarily project driven where the Company identifies efficiency measures that energy consumers can implement to reduce their energy usage. The Company presents retrofit opportunities to customers, get approval from them to proceed and submit the proposal to the local utility for pre-approval and determination of available incentives. Once the utility approves funding for the project, the Company installs the equipment, typically new heating, ventilation or air conditioning equipment, or replace lighting fixtures to more efficient models. The Company recognizes revenues for energy efficiency services when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable and collectability is reasonably assured. Due to the short-term nature of projects (typically two to three weeks), the Company utilizes the completed-contract method. The Company also assesses multiple contracts entered into by the same customer in close proximity to determine if the contracts should be combined for revenue recognition purposes. Revenues are recognized based upon factors such as passage of title, installation, payments and customer acceptance.

Cash and Cash Equivalents

The Company considers all highly liquid debt instruments purchased with an original maturity of 90 days or less to be cash equivalents.

Concentration of Credit Risk and Off-Balance Sheet Risk

Financial instruments that potentially expose the Company to concentrations of credit risk consist principally of cash and trade accounts receivable. The Company has no material off-balance sheet risk such as foreign exchange contracts, option contracts, or other foreign hedging arrangements. The Company places its cash with primarily two institutions, which management believes are of high credit quality. As of December 31, 2013, all of the Company’s cash is held in interest bearing accounts.

The Company provides credit in the form of invoiced and unbilled accounts receivable to customers in the normal course of business. Collateral is not required for trade accounts receivable, but ongoing credit evaluations of customers are performed. While the majority of the Company’s revenue is generated from retail energy transactions where the winning bidder pays a commission to the Company, commission payments for certain auctions can be paid by the lister, customer or a combination of both. Management provides for an allowance for doubtful accounts on a specifically identified basis, as well as through historical experience applied to an aging of accounts, if necessary. Trade accounts receivable are written off when deemed uncollectible. To date write-offs have not been material.

The following represents revenue and trade accounts receivable from bidders exceeding 10% of the total in each category:

In addition to its direct relationship with bidders, the Company also has direct contractual relationships with listers for the online procurement of certain of their energy, demand response or environmental needs. These listers are primarily large businesses and government organizations and do not have a direct creditor relationship with the Company. For the years ended December 31, 2013 and 2012, no energy consumer represented more than 10% individually of the Company’s aggregate revenue.

Inventory

Inventory is maintained in the Company’s Energy efficiency services segment and consists of prepaid expendables and project materials. Prepaid expendables represents consumable components that are used in project installations and are stated at the lower of cost or market, with cost being determined on a first-in, first-out (FIFO) basis. Historical inventory usage and current trends are considered in estimating both excess and obsolete inventory. To date, there have been no material write-downs of inventory and therefore no allowance for excess or obsolete inventory was recorded at December 31, 2013 and 2012. Project materials represent direct costs incurred on projects-in-process as of each reporting period.

Property and Equipment

Property and equipment is stated at cost. Depreciation is provided on a straight-line basis over the estimated useful lives of the related assets or the life of the related lease, whichever is shorter, which range from 3 to 10 years.

Investment / Convertible Note Receivable

In 2010, the Company made a strategic investment in the form of a two-year $650,000 convertible note with Retroficiency, Inc. (“Retroficiency”). The convertible note accrued interest at 9% per annum with principal and interest due at the end of the term on July 22, 2012. It included optional and automatic conversion rights to convert into Retroficiency shares at $0.54 per share and was subject to adjustment in certain circumstances. During the fourth quarter of 2011, Retroficiency executed a qualified financing in the form of Series A Preferred Stock at a price in excess of the Company’s conversion price and all principal and interest amounts outstanding under the convertible note receivable at the time of the financing were converted into Series A Preferred Stock. In March 2012, the Company sold its investment in Retroficiency at a premium to its carrying value. As a result, a gain of approximately $53,000 was recorded as other income in the accompanying consolidated statements of operations for the year ended December 31, 2012.

Other Assets

Certain acquired software and significant enhancements to the Company’s software are capitalized in accordance with Accounting Standards Codification (“ASC”) 350-40, “Internal-Use Software” (“ASC 350-40”). Internally developed software costs capitalized in 2013 amounted to $58,500. No internally developed software costs were capitalized in 2012 or 2011. The Company amortized internally developed and purchased software over the estimated useful life of the software (generally three years). During 2013, 2012 and 2011, approximately $2,000, $18,000 and $113,000 were amortized to cost of revenues, respectively. Accumulated amortization was approximately $1,223,000 and $1,221,000 at December 31, 2013 and 2012, respectively. Pre- and post- software implementation and configuration costs have historically been immaterial and charged to cost of revenue as incurred. In addition, $400,000 of certain long term prepaid partner payments are included in other assets at December 31, 2013, and $500,000 was included in the balance at December 31, 2012.

Intangible Assets

The Company uses assumptions in establishing the initial carrying value, fair value and estimated lives of its intangible assets. The criteria used for these assumptions include management’s estimate of the asset’s continuing ability to generate positive income from operations and positive cash flow in future periods compared to the carrying value of the asset, as well as the strategic significance of any identifiable intangible asset in the Company’s business objectives. If assets are considered impaired, the impairment recognized is the amount by which the carrying value of the assets exceeds the fair value of the assets. Useful lives and related amortization expense are based on an estimate of the period that the assets will generate revenues or otherwise be used by the Company. Factors that would influence the likelihood of a material change in the Company’s reported results include significant changes in the asset’s ability to generate positive cash flow, a significant decline in the economic and competitive environment on which the asset depends and significant changes in the Company’s strategic business objectives.

Intangible assets consist of customer relationships and contracts, purchased technology and other intangibles, and are stated at cost less accumulated amortization. Intangible assets with a finite life are amortized using the straight-line method over their estimated useful lives, which range from one to ten years.

Impairment of Long-Lived and Intangible Assets

In accordance with ASC 350, “Intangibles – Goodwill and Other” (“ASC 350”), the Company periodically reviews long-lived assets and intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable or that the useful lives of those assets are no longer appropriate. Recoverability of these assets is determined by comparing the forecasted undiscounted net cash flows of the operation to which the assets relate to the carrying amount. No impairment of the Company’s long-lived assets was recorded as no change in circumstances indicated that the carrying value of the assets was not recoverable during the years ended December 31, 2013 and 2012.

Goodwill & Indefinite-Lived Intangible Assets

The Company uses assumptions in establishing the initial carrying value and fair value of its goodwill and indefinite-lived intangibles. Goodwill represents the excess of the purchase price over the fair value of identifiable net assets of acquired businesses. Indefinite-lived intangibles are intangible assets whose useful lives are indefinite in that their lives extend beyond the foreseeable horizon – that is there is no foreseeable limit on the period of time over which it is expected to contribute to the cash flows of the reporting entity. The Company accounts for these items in accordance with ASC 350, under which goodwill and intangible assets having indefinite lives are not amortized but instead are assigned to reporting units and tested for impairment annually or more frequently if changes in circumstances or the occurrence of events indicate possible impairment.

The Company performs its annual impairment test at the end of the fourth fiscal quarter of each year, or earlier, if indicators of potential impairment exist. This impairment test is performed for each of its segments – Energy procurement and Energy efficiency services – which have been determined to be the Company’s reporting units. The impairment test for goodwill and indefinite-lived intangibles is a three-step process. Step 0 gives entities the option of first performing a qualitative assessment to test for impairment on a reporting-unit-by-reporting-unit basis. If after performing the qualitative assessment, an entity concludes that it is more-likely-than-not (“MLTN”, typically quantified as a likelihood of more than 50%) that the fair value of a reporting unit is less than its carrying amount, then the entity would perform a two-step impairment test. However, if, after applying the qualitative assessment, the entity concludes that it is not MLTN that the fair value is less than the carrying amount, the two step impairment test is not required. Step one consists of a comparison of the fair value of a reporting unit with its carrying amount, including the goodwill allocated to each reporting unit. If the carrying amount is in excess of the fair value, step two requires the excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of the reporting unit’s goodwill to be recorded as an impairment loss. To determine the fair value of each of the reporting units as a whole, the Company uses a discounted cash flow analysis, which requires significant assumptions and estimates about the future operations of each reporting unit. Significant judgments inherent in this analysis include the determination of appropriate discount rates, the amount and timing of expected future cash flows and growth rates. The cash flows employed in the discounted cash flow analyses are based on financial forecasts developed by management. The discount rate assumptions are based on an assessment of the Company’s risk adjusted discount rate, applicable for each reporting unit. In assessing the reasonableness of the determined fair values of the reporting units, the Company evaluates its results against its current market capitalization.

As of December 31, 2013 and 2012, the Company performed a step one analysis on both the energy procurement and energy efficiency services reporting units and determined that their indicated fair values substantially exceeded their carrying values. The Company relied on a weighted average cost of capital of 15.75% and 16.15% for each reporting unit as of December 31, 2013 and 2012, respectively, which takes into consideration certain specific small company premiums. The Company utilized a long-term growth rate of approximately 8% and 3% for the energy procurement and 15% and 20% efficiency services reporting units as of December 31, 2013 and 2012, respectively, and assumed a combined tax rate of 40% for both units and in both years.

As of December 31, 2013, the Company performed a step one analysis on the Company’s indefinite-life intangibles related to its Energy efficiency services segment customer relationships. Indefinite-life was assigned to the Company’s prime contractor relationships with the customer base in the Norwich Public (“Norwich”) and United Illuminated (“UI”) utility regions (“Prime”) and the Company’s relationships with the customer base within the Connecticut, Light and Power, UI and Norwich regions as a subcontractor (“Subcontractor”) at the NES acquisition date. The fair value of both the Prime and Subcontractor relationships exceeded their carrying values. The Company relied on a weighted average cost of capital of 16.6% for the Prime relationship and 15.7% for the subcontractor relationship as of December 31, 2013, which takes into consideration certain specific small company premiums. The Company utilized a long-term growth rate of approximately 10% for both the Prime and Subcontractor relationships and assumed a combined tax rate of 40% for both.  As of December 31, 2012, the Company performed a qualitative assessment of its indefinite-lived intangibles related to its Energy efficiency services segment customer relationships and determined that it was not likely that the fair value of a reporting unit was less than its carrying value.

Deferred Revenue and Customer Advances

Warranty

The Company’s Energy efficiency services segment provides its customers a one year warranty for all parts and labor in its installation workmanship. The Company has determined primarily from historical information and management’s judgment, that warranty costs are immaterial and no estimate for warranty cost is required at the time revenue is recognized. Should actual warranties differ from the Company’s estimates, an estimated warranty liability would be required.

Income Taxes

In accordance with ASC 740, “Income Taxes” (“ASC 740”), deferred tax assets and liabilities are determined at the end of each period based on the future tax consequences that can be attributed to net operating loss carryforwards, as well as differences between the financial statement carrying amounts of the existing assets and liabilities and their respective tax basis. Deferred income tax expense or credits are based on changes in the asset or liability from period to period. Valuation allowances are provided if, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The realization of deferred tax assets is dependent upon the generation of future taxable income. In assessing the requirement of a valuation allowance, the Company considers past performance, expected future taxable income, and qualitative factors which the Company considers to be appropriate in estimating future taxable income. The Company’s forecast of expected future taxable income is for future periods that can be reasonably estimated. Results that differ materially from current expectations may cause the Company to change its judgment on future taxable income and the necessity of a tax valuation allowance.

The Company has reviewed the tax positions taken, or to be taken, in its tax returns for all tax years currently open to examination by the taxing authority in accordance with ASC 740’s recognition and measurement standards. At December 31, 2013, there are no expected material, aggregate tax effects of differences between tax return positions and the benefits recognized in the Company’s consolidated financial statements. The Company accounts for interest and penalties related to uncertain tax positions as part of its provision for income taxes.

Stock-based Compensation

The Company recognizes the compensation from stock-based awards on a straight-line basis over the requisite service period of the award. Stock-based awards to employees consisted of grants of stock options for the years ended December 31, 2013, 2012 and 2011 and grants of restricted stock for the years ended December 31, 2013 and 2012, respectively. The restrictions on the restricted stock lapse over the vesting period. The vesting period of stock-based awards is determined by the board of directors, and is generally four years for employees.

The Company accounts for transactions in which services are received from non-employees in exchange for equity instruments based on the fair value of such services received or of the equity instruments issued, whichever is more reliably measured. There were no equity instruments granted to non-employees for the year ended December 31, 2013. For the years ended December 31, 2012 and 2011 stock-based awards to non-employees consisted of grants of stock warrants. The vesting period of stock warrants granted ranged from one to seven years.

Leases

Rent under non-cancelable operating leases that include scheduled rent increases are accounted for on a straight-line basis over the lease term.  Allowances and other lease incentives provided by the lessor are amortized on a straight-line basis as a reduction of rent expense.  The difference between straight-line expense and rent paid is recorded as a deferred rent liability in the consolidated balance sheet.

Advertising Expense

Advertising expense primarily includes promotional expenditures and is expensed as incurred. Advertising expenses incurred were approximately $229,000, $205,000 and $144,000 for the years ended December 31, 2013, 2012 and 2011, respectively.

Comprehensive Income (Loss)

ASC 220, “Comprehensive Income” (“ASC 220”), establishes standards for reporting and displaying comprehensive (loss) income and its components in financial statements. Comprehensive (loss) income is defined as the change in stockholders’ equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. The comprehensive (loss) income for all periods presented consisted only of the reported net (loss) income.

Fair Value of Financial Instruments

The Company’s financial instruments include cash and cash equivalents, accounts receivable, accounts payable, accrued expenses (including contingent consideration) and debt. The carrying amounts for these financial instruments reported in the consolidated balance sheets approximate their fair values.

Fair Value Measurements

The Company follows ASC 820, “Fair Value Measurements and Disclosures” (“ASC 820”), for fair value measurements. ASC 820 defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. The standard provides a consistent definition of fair value, which focuses on an exit price, which is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The standard also prioritizes, within the measurement of fair value, the use of market-based information over entity specific information and establishes a three-level hierarchy for fair value measurements based on the nature of inputs used in the valuation of an asset or liability as of the measurement date.

The hierarchy established under ASC 820 gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3).

Level 1 — Pricing inputs are quoted prices available in active markets for identical investments as of the reporting date. As required by ASC 820-10, the Company does not adjust the quoted price for these investments, even in situations where the Company holds a large position and a sale could reasonably impact the quoted price.

Level 2 — Pricing inputs are quoted prices for similar investments, or inputs that are observable, either directly or indirectly, for substantially the full term through corroboration with observable market data. Level 2 includes investments valued at quoted prices adjusted for legal or contractual restrictions specific to these investments.

Level 3 — Pricing inputs are unobservable for the investment, that is, inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Level 3 includes investments that are supported by little or no market activity.

Segment Reporting

ASC 280, “Segment Reporting” (“ASC 280”), establishes standards for reporting information about operating segments in financial statements. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision maker is the president and chief executive officer. The Company’s chief operating decision maker reviews the results of operations based on two industry segments: Energy procurement and Energy efficiency services.

Recent Accounting Pronouncements

In July 2013, Accounting Standards Update (“ASU”) 2013-11, "Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists" (“ASU 2013-11”), was issued which defines the presentation requirements of an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the financial statements. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted and retrospective application is permitted but not required. The Company does not expect the application of this ASU to have an impact on its consolidated financial statements.

Acquisitions

Acquisitions	12 Months Ended

Acquisitions	'
	NOTE 3 — ACQUISITIONS
	The Company accounts for acquisitions using the purchase method in accordance with ASC 805, “Business Combinations.” The results of operations of acquisitions have been included in the accompanying consolidated financial statements as of the dates of the acquisition. There were no acquisitions in 2013.  Total cash paid for acquisitions was $8.1 million and $10.4 million in 2012 and 2011, respectively. The Company recognized $0.2 million and $0.7 million of total acquisition costs in 2012 and 2011, respectively, that were included in general and administrative expense in the accompanying consolidated statements of operations.
	NEP
	On October 3, 2012, the Company acquired substantially all of the assets and certain obligations of Northeast Energy Partners, LLC (“NEP”) pursuant to an Asset Purchase Agreement (the “Asset Purchase Agreement”) between the Company, NEP, and its members. NEP is a Connecticut based energy management and procurement company.
	The acquisition-date fair value of the consideration transferred totaled approximately $12.1 million, which consisted of the following:
				Purchase Price
	Cash			$	7,910,959
	Notes payable to seller				2,000,000
	Contingent consideration				2,219,000
	Total consideration			$	12,129,959
	The Company funded the initial $7.9 million cash portion of the purchase price through the issuance of long-term debt. See Note 15 “Credit Arrangements” for details of long-term debt.
	The fair value of the Notes payable to seller was recorded at the face amount of the Notes entered into at the date of acquisition due to their short-term maturity and market rate of interest. The Notes payable to seller bears interest at 4%. On October 1, 2013, the Company paid the first installment of $1,500,000 against the Notes payable to seller. As of December 31, 2013, $500,000 was outstanding under the Notes payable to seller, which is due on April 1, 2014.
	As part of the total consideration, NEP could have earned up to $3.2 million in contingent consideration if certain performance criteria were met for the twelve months ending September 30, 2013. This potential contingent consideration consisted of $2.5 million in cash and 153,153 shares of common stock. As of December 31, 2012, the Company valued this contingent payment at $2.2 million, which was recorded within current liabilities as accrued contingent consideration in the consolidated balance sheet. In measuring the fair value of the contingent consideration, the Company assigned probabilities to the performance criteria, based among other things on the nature of the performance criteria and the Company’s due diligence performed at the time of the acquisition. On December 31, 2013 the Company paid $1.3 million in cash and issued 76,577 shares of common stock valued at $0.3 million which represented the final contingent consideration payment related to the acquisition. As a result, the Company recognized a $0.6 million reduction in general and administrative expense for the year ended December 31, 2013, eliminating the accrued contingent consideration related to this acquisition.
	The following table summarizes the allocations of purchase price, which was finalized at December 31, 2012:
				Allocations
	Unbilled accounts receivable			$	837,693
	Fixed assets				26,765
	Current liabilities				(415,078	)
	Intangible assets				7,820,000
	Goodwill				3,860,579
	Net assets acquired			$	12,129,959
	The purchase price was allocated to the tangible and intangible assets and liabilities assumed based on estimates of their respective fair values at the date of acquisition with the remaining unallocated purchase price recorded as goodwill. Fair value of intangible assets was determined using a combination of the multi-period excess earnings method, the comparative business valuation method and relief from royalty method. The goodwill recognized is attributable primarily to future revenue generation resulting from expected synergies, expanded product lines and new markets and is expected to be deductible for tax purposes over a period of 15 years.
	The intangible assets, excluding goodwill, are being amortized on a straight-line basis over their weighted average lives as follows:
		Fair Value				Weighted Average Lives
	Customer contracts	$	2,500,000			4 years
	Non-compete agreements		900,000			5 years
	Customer relationships		4,000,000			10 years
	Trade names		420,000			4 years
	Total intangible assets	$	7,820,000
	GSE
	On October 31, 2011, the Company acquired substantially all of the assets and certain obligations of GSE Consulting, L.P. (“GSE”) for a maximum purchase price of $13.1 million. GSE is a Texas based energy management and procurement company. The purchase price was $8.6 million, consisting of $3.9 million in cash, $1.5 million in cash to pay off GSE debt, and 1.0 million shares of the Company’s Common Stock valued at $3.2 million. In addition, GSE could earn up to $4.5 million of contingent consideration in cash based on the achievement of certain annualized new booking and renewal rate targets to be measured over a two-year period through October 2013.
	The acquisition-date fair value of the consideration transferred totaled $12.9 million, which consisted of the following:
				Purchase Price
	Cash			$	5,400,251
	Common stock (1,000,000 shares)				3,210,000
	Contingent consideration				4,328,000
	Total consideration			$	12,938,251
	The fair value of the 1,000,000 common shares issued was determined based on the closing market price of the Company’s common shares on the acquisition date.
	The fair value of the contingent consideration was based on the weighted probability of achievement of certain performance milestones. In measuring the fair value of the contingent consideration, the Company assigned probabilities to the performance criteria, based among other things on the nature of the performance criteria and the Company’s due diligence performed at the time of the acquisition. The contingent consideration was tied to the achievement of certain performance criteria for the 3-month period ended December 31, 2011 (“2011 GSE contingent consideration”), the twelve month period ended October 31, 2012 (“2012 GSE contingent consideration”) and the twelve month period ended October 31, 2013 (“2013 GSE contingent consideration”). The contingent consideration earns interest at 4% per annum, which is payable at each respective due date.
	In January 2012, the Company paid $2.0 million to GSE representing full attainment of the 2011 GSE contingent consideration. In January 2013, the Company paid an additional $1.3 million to GSE representing its attainment of the annualized new booking target for the 2012 GSE contingent consideration. The renewal rate target for the 2012 GSE contingent consideration in the amount of $0.3 million was not attained but has been disputed by GSE. Based on management’s estimates, the annualized new bookings target for the 2013 GSE contingent consideration was attained representing $0.8 million of the $1.0 million total potential contingent consideration payment for that period. The renewal rate target for the 2013 GSE contingent consideration representing a potential $0.3 million of the total payment was not attained but has been disputed by GSE. The Company’s estimates are currently being reviewed by GSE. In addition, the agreement provided for a working capital adjustment tied to the collection of backlog during the 15-month period from November 1, 2011 through January 31, 2013, as defined in the purchase agreement. Based on management’s estimate of the working capital adjustment, no payment has been made to GSE related to the 2013 GSE contingent consideration. GSE has disputed this calculation and the companies are currently in negotiations to determine a mutually acceptable settlement on all disputed items. As a result, the Company has estimated a $1.0 million accrual related to the 2012 and 2013 GSE contingent consideration which is included within current liabilities in the Company’s consolidated balance sheets as of December 31, 2013.
	The following table summarizes the estimated fair values of the assets and liabilities assumed at the acquisition date:
				Allocations
	Current assets			$	8,698
	Fixed assets				100,088
	Other assets				15,030
	Capital leases				(27,858	)
	Intangible assets				7,080,000
	Goodwill				5,762,293
	Net assets acquired			$	12,938,251
	The purchase price was allocated to the tangible and intangible assets and liabilities assumed based on estimates of their respective fair values at the date of acquisition with the remaining unallocated purchase price recorded as goodwill. Fair value of intangible assets was determined using a combination of the multi-period excess earnings method, the comparative business valuation method and the relief from royalty method. The goodwill recognized is attributable primarily to future revenue generation resulting from expected synergies, expanded product lines and new markets and is expected to be deductible for tax purposes over a period of 15 years. Acquisition costs of approximately $0.4 million were recorded in general and administrative expense in 2011.
	Management is responsible for the valuation of net assets acquired and considered a number of factors, including valuations and appraisals, when estimating the fair values and estimated useful lives of acquired assets and liabilities. At December 31, 2011 the allocation of purchase price had been finalized. The intangible assets, excluding goodwill, are being amortized on a straight-line basis over their weighted average lives as follows:
		Fair Value				Weighted Average Lives
	Non-compete agreements	$	1,280,000			5 years
	Customer relationships	$	3,480,000			10 years
	Customer contracts		1,650,000			3 years
	Trade names		670,000			4 years
	Total intangible assets	$	7,080,000
	NES
	On October 13, 2011, the Company acquired substantially all of the assets and certain obligations of Northeast Energy Solutions, LLC (“NES”) for a maximum purchase price of $4.8 million. NES, located in Cromwell, Connecticut, focuses on turn-key electrical and mechanical energy efficiency measures serving commercial, industrial and institutional customers.
	The acquisition-date fair value of the consideration transferred totaled $4.6 million, which consisted of the following:
				Purchase Price
	Cash			$	1,004,131
	Common stock (83,209 shares)				252,122
Notes payable to seller				3,000,000
Contingent consideration				357,813
Total consideration			$	4,614,066
The fair value of the 83,209 common shares issued was determined based on the closing market price of the Company’s common shares on the acquisition date.
The fair value of the Notes payable to seller was recorded at the face amount of the notes entered into at the date of acquisition due to their short-term maturity and market rate of interest. During 2012 the Company paid $3,000,000 in Notes payable to seller, including interest paid on each tranche at the respective due dates, and no amounts remained outstanding under these notes as of December 31, 2013 and December 31, 2012.
In January 2012 the Company paid $250,000 in NES contingent consideration. In March 2013, the Company paid $125,000 related to the NES contingent consideration representing the final payment related to the acquisition. There were no amounts outstanding as of December 31, 2013.
The following table summarizes the estimated fair values of the assets and liabilities assumed at the acquisition date:
			Allocations
Current assets			$	1,875
Fixed assets				168,530

Goodwill				1,534,870
Net assets acquired			$	4,614,066
The purchase price was allocated to the tangible and intangible assets and liabilities assumed based on estimates of their respective fair values at the date of acquisition with the remaining unallocated purchase price recorded as goodwill. Fair value of intangible assets was determined using a combination of the multi-period excess earnings method, the income approach and the cost replacement approach. The goodwill recognized is attributable primarily due to future revenue generation resulting from expanded product lines and new markets and is expected to be deductible for tax purposes over a period of 15 years. Acquisition costs of approximately $0.1 million were recorded in general and administrative expense in 2011.
Management is responsible for the valuation of net assets acquired and considered a number of factors, including valuations and appraisals, when estimating the fair values and estimated useful lives of acquired assets and liabilities. At December 31, 2011 the allocation of purchase price had been finalized. The intangible assets, excluding goodwill, are being amortized on a straight-line basis over their weighted average lives as follows:
	Fair Value				Weighted Average Lives
Customer relationships	$	991,600			9 years
Customer relationships  - indefinite life		1,736,000			N/A
Non-compete agreements		234,900			5 years
Total intangible assets	$	2,962,500
Co-eXprise
On September 13, 2011, the Company acquired certain contracts and assumed certain liabilities of the Co-eXprise, Inc.’s (now called Directworks Inc. (“Directworks”)) energy procurement business for $4.0 million in cash. Directworks, located in Wexford Pennsylvania, provides cloud-based software solutions purpose-built for manufacturers to improve supplier collaboration, total cost visibility, and the efficiency of sourcing and supplier management activities.
The following table summarizes the estimated fair values of the assets and liabilities assumed at the acquisition date:
			Allocations
Unbilled accounts receivable			$	412,609
Current liabilities				(4,000	)
Intangible assets				1,760,000
Goodwill				1,831,391
Net assets acquired			$	4,000,000
The fair value of accounts receivable acquired on September 13, 2011 was approximately $413,000. The gross contractual amount of these accounts receivable was approximately $460,000, of which $47,000 was not expected to be collected. Actual collections exceeded the fair value of the unbilled accounts receivable at acquisition by $85,000, which has been recorded as a reduction in general and administrative expense for the year ended December 31, 2012.
The purchase price was allocated to the tangible and intangible assets and liabilities assumed based on estimates of their respective fair values at the date of acquisition with the remaining unallocated purchase price recorded as goodwill. Fair value of intangible assets was determined using a combination of the income approach and cost approach. The goodwill recognized is attributable primarily to expected synergies of Co-eXprise and is expected to be deductible for tax purposes over a period of 15 years. Acquisition costs of approximately $0.2 million were recorded in general and administrative expense in 2011.
Management is responsible for the valuation of net assets acquired and considered a number of factors, including valuations and appraisals, when estimating the fair values and estimated useful lives of acquired assets and liabilities. At December 31, 2011 the allocation of purchase price had been finalized. The intangible assets, excluding goodwill, are being amortized on a straight-line basis over their weighted average lives as follows:
	Fair Value				Weighted Average Lives
Non-compete agreements	$	170,000			5 years

Customer contracts		1,010,000			2.5 years
Total intangible assets	$	1,760,000
Other Acquisitions
In December 2012 the Company acquired two additional businesses, primarily to expand its customer base in the procurement and efficiency markets. The total consideration of these acquisitions was $0.2 million. In allocating the total purchase consideration for these allocations based on estimated fair values, the Company recorded approximately $0.1 million of identifiable intangible assets which consisted of customer relationships with a weighted average life of one year.
The NES acquisition operating results have been included within the Company’s Energy efficiency services segment since the date of acquisition. The Co-eXprise contracts and GSE and NEP operations were integrated into the Company’s Energy procurement segment from the respective dates of acquisition and, therefore, discrete operating results are not maintained or reviewed by the Company’s chief operating decision maker for those operations. The following unaudited pro forma information assumes that the acquisition of NEP had been completed as of the beginning of 2012:
	Years Ended  December 31,

Weighted average shares outstanding – diluted		11,958,689				11,478,718
The pro forma financial information is not necessarily indicative of the results to be expected in the future as a result of the acquisitions of NEP, as the acquisition did not necessarily reflect the purchase of stand-alone or complete operations, and included several non-recurring revenue events.

	The Company does not invoice bidders for the commissions earned on retail electricity, certain natural gas and demand response transactions and, therefore, reports a significant portion of its receivables as “unbilled.” Unbilled accounts receivable represent management’s best estimate of energy provided by the energy suppliers to the energy consumers for a specific completed time period at contracted commission rates.
	The Company generally invoices bidders for commissions earned on wholesale and a substantial portion of retail natural gas transactions as well as energy efficiency customers, which are reflected as billed accounts receivable. For natural gas and wholesale transactions, the total commission earned on these transactions is recognized upon completion of the procurement event and are generally due within 30 days of invoice date. For efficiency projects, revenue is recognized and invoiced upon project installation and acceptance, as required, and are generally due within 30 days of invoice date. In addition, the Company invoices the bidder, lister or combination of both for certain auctions performed for environmental commodity product transactions. These transactions are earned and invoiced either upon lister acceptance of the auction results or, in some cases, upon delivery of the credits or cash settlement of the transaction. For the years ended December 31, 2013 and 2012, the Company provided $150,000 and $103,857 as an allowance for doubtful accounts, respectively. To date, write-offs have not been material.

	Preferred Stock
	The Company’s Amended and Restated Certificate of Incorporation, as amended, authorizes 5,000,000 shares of $0.0001 par value undesignated preferred stock for issuance by the Company’s board of directors. No preferred shares have been issued as of December 31, 2013 and 2012.
	Common Stock
	On October 31, 2011, the Company issued 1.0 million shares of common stock of the Company (equal to approximately $3.2 million) pursuant to an Asset Purchase Agreement between the Company, GSE, Glenwood Energy Partners, Ltd. and Gulf States Energy, Inc.
	On October 13, 2011, the Company issued 83,209 shares of common stock of the Company (equal to approximately $0.3 million) to the Members of NES pursuant to an Asset Purchase Agreement between the Company, NES and the Members of NES.
	In April 2010, the Company filed an S-3 registration statement with the Securities and Exchange Commission, or SEC, using a “shelf” registration, or continuous offering, process. Under this shelf registration process, the Company may, from time to time, issue and sell any combination of preferred stock, common stock or warrants, either separately or in units, in one or more offerings with a maximum aggregate offering price of $20,000,000, including the U.S. dollar equivalent if the public offering of any such securities is denominated in one or more foreign currencies, foreign currency units or composite currencies. On April 11, 2011, the Company issued approximately 1.5 million shares of common stock utilizing this shelf registration to several accredited institutional investors at $3.60 per share yielding proceeds of approximately $5.3 million, net of $0.2 million of expenses.
	Treasury Stock
	In connection with the vesting of restricted stock granted to employees the Company withheld shares with value equivalent to employees’ minimum statutory obligation for the applicable income and other employment taxes, and remitted the cash to the appropriate taxing authorities. The total shares withheld of 9,091 and 643 for the years ended December 31, 2013 and 2012, respectively, were based on the value of the restricted stock on their vesting date as determined by the Company’s closing stock price. Total payment for employees’ tax obligations was approximately $35,000 and $3,000 for the years ended December 31, 2013 and 2012, respectively. These net-share settlements had the effect of share repurchases by the Company as they reduced the number of shares that would have otherwise been issued as a result of the vesting and did not represent an expense to the Company.
	Common Stock Warrants
	On October 3, 2012, the Company issued warrants to Silicon Valley Bank (“SVB”) for the purchase of 45,045 shares of the Company’s common stock at a per share price of $4.44 in connection with a Fourth Loan Modification Agreement (the “Fourth Modification Agreement”) with SVB. The warrants have a seven year life.

Earnings (Loss) Per Share	'
	NOTE 9 — EARNINGS (LOSS) PER SHARE
	As of December 31, 2013, 2012 and 2011, the Company only had one issued and outstanding class of stock – common stock. As a result, the basic earnings or loss per share for the years ended December 31, 2013, 2012 and 2011 is computed by dividing net (loss) income by the weighted average number of common shares outstanding for the period.
	The following table provides a reconciliation of the denominators of the Company’s reported basic and diluted earnings per share computation for the years ended December 31, 2013, 2012 and 2011, respectively:
		Years Ended December 31,
		2013		2012		2011
	Weighted number of common shares - basic		11,998,019		11,901,172		10,521,910
	Common stock options		-		21,348		-
	Common stock warrants		-		22,653		-
	Unvested restricted stock		-		13,516		-
	Total common stock equivalents		11,998,019		11,958,689		10,521,910
	The computed loss per share does not assume conversion, exercise, or contingent exercise of securities that would have an anti-dilutive effect on loss per share. As the Company was in a net loss position for the years ended December 31, 2013 and 2011, all common stock equivalents in those years were anti-dilutive.
	For the year ended December 31, 2013, 745,917, 49,545 and 202,000 shares issuable relative to common stock options, common stock warrants and restricted stock, respectively, were excluded from net loss per share since the inclusion of such shares would be anti-dilutive. For the year ended December 31, 2012, 713,301 and 45,045 shares issuable relative to common stock options and common stock warrants, respectively, were excluded from net loss per share since the inclusion of such shares would be anti-dilutive. For the year ended December 31, 2011, 707,281, 364,500 and 1,856 shares issuable relative to common stock options, common stock warrants and restricted stock, respectively, were excluded from net loss per share since the inclusion of such shares would be anti-dilutive.  The Company did not declare or pay any dividends in 2013, 2012 and 2011.

StockBased_Compensation

Stock-Based Compensation	12 Months Ended
	Dec. 31, 2013
Stock-Based Compensation	'
	NOTE 10 — STOCK-BASED COMPENSATION
	For the year ended December 31, 2013, share based awards consisted of grants of stock options and restricted stock, for the year ended December 31, 2012, share based awards consisted of grants of stock options, restricted stock and stock warrants and for the year ended December 31, 2011 share based awards consisted of grants of stock options and stock warrants. The Company recognizes the compensation from stock-based awards on a straight-line basis over the requisite service period of the award. The vesting period of stock-based awards is determined by the board of directors, and is generally four years for employees. The restrictions on the restricted stock lapse over the vesting period, which is typically four years. The per-share weighted-average fair value of stock options granted during the years ended December 31, 2013, 2012 and 2011 was $2.37, $2.80 and $2.20, respectively, on the date of grant, using the Black-Scholes option-pricing model with the following weighted-average assumptions:
	Year Ended December 31,	Expected Dividend Yield		Risk-Free Interest Rate		Expected Life		Expected Volatility
	2013		0%		1.21%	4.75 years			84%
	2012		0%		0.71%	4.75 years			94%
	2011		0%		0.89%	4.75 years			99%
	The per-share weighted-average fair value of stock warrants granted during the years ended December 31, 2012 and 2011 was $3.10 and $0.72, respectively, on the date of grant, using the Black-Scholes option-pricing model with the following weighted-average assumptions:
	Year Ended December 31,	Expected Dividend Yield		Risk-Free Interest Rate		Expected Life		Expected Volatility
	2012		0%		0.61%	7.00 years			94%
	2011		0%		0.12%	0.63 years			60%
	The Company elected to use the Black-Scholes option pricing model to determine the weighted average fair value of options and warrants granted. The Company determined the volatility for stock options based on the reported closing prices of the Company’s stock. The expected life of stock options has been determined utilizing the “simplified” method as prescribed by the SEC’s Staff Accounting Bulletin No. 107, “Stock-based Payment”. The expected life of stock warrants is based on the contract term of the warrants. The risk-free interest rate is based on a treasury instrument whose term is consistent with the expected life of the stock options and stock warrants. The Company has not paid and does not anticipate paying cash dividends on its common stock; therefore, the expected dividend yield is assumed to be zero. In addition, ASC 718, “Compensation – Stock Compensation” (“ASC 718”), requires companies to utilize an estimated forfeiture rate when calculating the expense for the period. As a result, the Company applied estimated forfeiture rates to unvested stock-based compensation of 10% for stock options and restricted stock for the years ended December 31, 2013, 2012 and 2011, respectively, in determining the expense recorded in the accompanying consolidated statements of operations. The Company did not apply an estimated forfeiture rate to unvested stock-based compensation for stock warrants for the years ended December 31, 2013, 2012 and 2011, in determining the expense recorded in the accompanying consolidated statements of operations.
	The approximate total stock-based compensation expense for the periods presented is included in the following expense categories:
		Years Ended December 31,
		2013		2012		2011
	Cost of revenue	$	89,000	$	79,000	$	69,000
	Sales and marketing		249,000		207,000		356,000
	General and administrative		262,000		180,000		185,000
	Total stock-based compensation	$	600,000	$	466,000	$	610,000
	As of December 31, 2013, there was approximately $1,380,000 of unrecognized compensation expense related to stock-based awards, including approximately $810,000 related to non-vested stock option awards that is expected to be recognized over a weighted-average period of 2.42 years and approximately $570,000 related to non-vested restricted stock awards that is expected to be recognized over a weighted average period of 2.58 years. See Note 8 to the accompanying consolidated financial statements for a summary of activity under the Company’s stock-based employee compensation plans for the years ended December 31, 2013, 2012 and 2011.
	The Company accounts for transactions in which services are received from non-employees in exchange for equity instruments based on the fair value of such services received or of the equity instruments issued, whichever is more reliably measured. During 2012, the Company issued warrants to SVB for the purchase of 45,045 shares of the Company’s common stock in conjunction with a Fourth Loan Modification Agreement (the “Fourth Modification Agreement”). As a result of the warrants issued to SVB, the Company recognized a debt discount of approximately $140,000, of which approximately $130,000 was unamortized and recorded against long term debt on the Company’s December 31, 2012 consolidated balance sheet, and approximately $10,000 was recorded as interest expense in the consolidated statement of operations for the year ended December 31, 2012. As a result of the extinguishment of the SVB loan during 2013, the Company expensed the remaining unamortized debt discount to interest expense in the amount of approximately $130,000 (See Note 15). During 2011, stock warrants were granted for 300,000 shares of common stock to consultants in consideration for services performed, for which the Company recognized a charge of approximately $19,000 and $197,000 to sales and marketing expense in the consolidated statement of operations for the years ended December 31, 2012 and 2011, respectively. During 2010, stock warrants were granted for 64,500 shares of common stock to consultants in consideration for services performed, for which the Company recognized a charge of approximately $4,000 to general and administrative expense in the consolidated statement of operations for the year ended December 31, 2011.

	In 2012, the Company entered into an agreement to lease a facility in Enfield CT, used to support its operations related to its acquisition of NEP. The facility is owned by a real estate holding company owned equally by the former owners of NEP. The managing member of the holding company is an employee of the Company. Rent paid by the Company to this real estate holding company amounted to approximately $120,000 and $29,000 in 2013 and 2012, respectively.
	Pursuant to the Company’s 2012 acquisition of assets and certain liabilities of NEP, the Company issued Notes payable to seller and contingent consideration as part of the purchase price. Subsequent to the acquisition, one of the owners of NEP became an employee of the Company, while retaining an indirect interest in purchase consideration due to NEP. The first installment of Notes payable to NEP in the amount of $1,500,000 was paid in October 2013, with the remaining amount of $500,000 due in April 2014 and reflected in the Company’s December 31, 2013 consolidated balance sheet as a current liability. Additionally, approximately $66,000 and $20,000 of interest expense related to the notes payable was reflected in the Company’s consolidated statements of operations for the years ended December 31, 2013 and 2012, respectively. Contingent consideration, valued at approximately $1,575,000 and consisting of a cash payment of $1,250,000 and an issuance of 76,577 shares of the Company’s common stock related to this acquisition, was paid in December 2013. There were no further payments due related to contingent consideration for the NEP acquisition.
	Pursuant to the Company’s 2011 acquisition of assets and certain liabilities of NES, the Company issued notes payable to the sellers and contingent consideration as part of the purchase price. Subsequent to the acquisition the three Members of NES became employees of the Company, while retaining an interest in purchase consideration due NES. Accrued contingent consideration of $120,312 related to the NES acquisition was reflected as a liability in the Company’s December 31, 2012 consolidated balance sheet. Additionally, approximately $113,000 and $32,000 of interest expense related to the notes was reflected in the Company’s accompanying consolidated statements of operations for the year ended December 31, 2012 and 2011, respectively. The Company’s obligations related to the notes and contingent consideration for the NES acquisition had been completed as of December 31, 2013.

	In the Company’s December 31, 2013 consolidated balance sheet, approximately $0.9 million of the Company’s deferred tax asset was included with current assets and approximately $7.2 million of the Company’s deferred tax asset was included with non-current assets.
	Pursuant to ASC 740, management has evaluated the positive and negative evidence bearing upon the realizability of its deferred tax assets, which are comprised principally of net operating loss carryforwards and other temporary differences. During the years ended December 31, 2013 and 2012, management concluded that it was more likely than not that the Company will recognize all of its deferred tax assets. During 2012, the Company released its valuation allowance which resulted in the recognition of a cumulative tax benefit of approximately $7.5 million. The Company continually evaluates additional facts representing both positive and negative evidence in the determination of the realizability of the deferred tax assets, including scheduling of deferred tax liabilities and projected taxable income. The underlying assumptions used in forecasting future taxable income requires significant judgment and take into account all available evidence, including past operating results and recent performance. The positive evidence considered was the most recent three years of cumulative taxable income, projected future taxable income, the length of carryforward periods of net operating losses and tax credits and current operating results. In addition, the Company has utilized $5.7 million of federal net operating loss carryforwards over the last four years. The primary negative evidence considered was the Company’s previous history of cumulative pre-tax losses, its limited experience in the Energy efficiency business and its current year pre-tax loss. Management has considered the weight of all available evidence in determining whether a valuation allowance was required and concluded the weight of the positive evidence was greater than the negative evidence making it more likely than not that the Company will recognize its deferred tax assets.
	A reconciliation of the Company’s federal statutory tax rate to its effective rate is as follows:

	As of December 31, 2013, the Company has federal net operating loss carryforwards of approximately $13.4 million which begin to expire in 2027, and state net operating loss carryforwards of approximately $1.8 million, which begin to expire in 2014. During 2013, approximately $0.4 million of state net operating loss carryforwards expired.
	The Company files income tax returns in the U.S. federal jurisdiction and in various states. The Company has reviewed the tax positions taken, or to be taken, in its tax returns for all tax years currently open to examination by the taxing authorities. With few exceptions, the Company is no longer subject to U.S. federal, state and local income tax examination by tax authorities for years before 2010. At December 31, 2013, there are no expected material, aggregate tax effects of differences between tax return positions and the benefits recognized in the consolidated financial statements.
	Under the provisions of the Internal Revenue Code, certain substantial changes in the Company’s ownership may have limited or may limit in the future the amount of net operating loss carryforwards which could be utilized annually to offset future taxable income and income tax liabilities. The amount of any annual limitation is determined based upon the Company’s value prior to an ownership change. The Company performed an internal analysis with the guidance of its third party tax adviser and determined that ownership changes that have occurred primarily in connection with stock offerings or in connection with acquisitions when the Company issued stock to the sellers have not limited the Company’s ability to fully utilize its net operating loss carryforwards.

	The Company determines the fair value of acquisition-related contingent consideration based on assessment of the probability that the Company would be required to make such future payment. Management assigns probabilities to each level of attainment and weights those probabilities to determine the amount to accrue at each reporting period. As the contingent consideration was based on financial or operational performance, management monitors performance against target and estimates future performance based on current forecasts. At December 31, 2013, all performance periods had concluded and calculations were based on actual performance. The final payment related to the NEP contingent consideration was made on December 31, 2013. Total adjustments made were to decrease fair value by $0.7 million. At December 31, 2013, the remaining contingent consideration balance represents management’s estimate of the amount that is expected to be paid to GSE in settlement of all contingent consideration amounts outstanding. The net result was a $0.1 million reduction in accrued contingent consideration. Changes to the fair value of contingent consideration are recorded in general and administrative expense. The following table provides a rollforward of the fair value, as determined by level 3 inputs, of the contingent consideration.

	On June 25, 2012, the Company relocated its corporate headquarters to 100 Front Street, Worcester, MA. In connection with this move, the Company entered into a ten-year lease for 12,000 square feet of office space at a rate comparable to rates paid under its former corporate office lease. The average annual rental commitment under this lease is approximately $320,000.
	The Company maintains operating leases for office space in nine locations in the U.S., paid in installments due the beginning of each month and that expire through May 2022. Future aggregate minimum payments under office space operating leases as of December 31, 2013 were as follows:
		Amount
	2014	$	670,028
	2015		664,540
	2016		634,160

	Total future minimum lease payments	$	4,289,834
	The accompanying consolidated statements of operations for the years ended December 31, 2013, 2012, and 2011 includes approximately $896,000, $742,000 and $443,000 of office rent expense, respectively. Rent expense associated with office leases is recognized on a straight-line basis, inclusive of scheduled rent increases and allowances, over the term of the lease agreements which resulted in a deferred rent liability of $217,000 and $150,000 as of December 31, 2013 and 2012, respectively.  In addition, the Company maintained leases for office equipment for which approximately $16,000 was charged to the accompanying consolidated statement of operations for the year ended December 31, 2013, and approximately $32,000 of future minimum lease payments will be incurred through 2018.
	Future aggregate minimum payments under this operating lease are as follows:
		Amount
	2014	$	120,150
	2015		120,150
	2016		120,150

	Litigation
	Three former employees/consultants of GSE Consulting, LP (“GSE”) have filed three separate complaints in Texas County Court alleging, among other things, claims related to breach of contract, quantum meruit, promissory estoppel, and tortious interference. Each plaintiff claims that GSE and/or the Company failed to pay commissions due for services that they provided prior to the date of the Company’s purchase of certain GSE assets, based on their respective employment or independent contractor agreements with GSE. Each plaintiff has also asserted claims for recovery of their attorneys’ fees. The Company denies the allegations and has filed counterclaims for damages, asserting claims for conversion, unjust enrichment, misappropriation of confidential information, and violation of the Texas Theft Liability Act against each of the plaintiffs. The Company has also filed a counterclaim against one of the plaintiffs for her breach of a non-competition and non-solicitation agreement, based on her working for a competitor of the Company’s during her 1-year restrictive period and her improper solicitation of former GSE customers on behalf of the competitor. The Company also filed cross claims against GSE for indemnification under the Asset Purchase Agreement in each of the three cases. In two of these cases, the Plaintiffs have asserted claims against GSE affiliates and their individual principals. The GSE affiliates and principals have also asserted cross claims against the Company seeking indemnification under the Asset Purchase Agreement. In December 2013, GSE amended its cross claims in one of the matters to include claims asserting breaches of the earnout provisions in the Asset Purchase Agreement. Also, in December 2013, the Company entered into mediation discussions with one of the plaintiffs. As a result, the Company agreed to pay the plaintiff a settlement that is subject to a confidentiality clause. The settlement amount was not material to the Company’s consolidated operating results or financial position and was accrued as of December 31, 2013. In return, the plaintiff agreed to drop all claims against the Company including all claims related to commissions due for past service. The settlement agreement was signed and filed with the court in January 2014. The Court assigned a trial date of May 5, 2014 for the cross claims remaining in the matter. Discovery has concluded in the remaining two matters and the court has assigned a trial date of September 29, 2014 for one of the cases. The remaining case is awaiting assignment of a trial date. The Company is awaiting a decision on its motion for summary judgment seeking dismissal of all claims against one of the two remaining plaintiffs, and is in the process of filing a motion for summary judgment against the other plaintiff.
	The Company has estimated the potential commissions allegedly due to the two remaining plaintiffs to be approximately $0.3 million. The Company has not recorded any accrual for contingent liabilities associated with the legal proceedings described above based on its belief that any potential loss, while reasonably possible, is not probable. The Company intends to defend these actions vigorously and is currently unable to estimate a range of payments, if any, it may be required to pay, with respect to these claims. Further, the Company believes that the resolution of these matters will not result in a material effect to its consolidated financial statements. However, due to uncertainties that accompany litigation of this nature, there could be no assurance that the Company will be successful, and the resolution of the lawsuits could have a material effect on its accompanying consolidated financial statements.
	From time to time, the Company may be subject to legal proceedings and claims arising from the conduct of its business operations, including litigation related to employment matters. While it is impossible to ascertain the ultimate legal and financial liability with respect to contingent liabilities, including lawsuits, management believe that the aggregate amount of such liabilities, if any, will not have a material adverse effect on the consolidated financial position and/or results of operations. It is possible, however, that future financial position or results of operations for any particular period could be materially affected by changes in the Company’s assumptions or strategies related to those contingencies or changes out of its control.

	Credit Facility
	On December 30, 2013, the Company entered into a Loan and Security Agreement (the “Agreement”) with Commerce that replaced the Company’s former $9.0 million credit facility with SVB. Under the Agreement, Commerce has committed to a three year revolving credit facility of up to $2.5 million (the “Revolver”) and a 60-month term loan of $6.0 million  (the “Term Loan”). The former SVB credit facility was a $9.0 million credit facility consisting of a $6.5 million term note and a $2.5 million line-of-credit. The Company utilized the proceeds from the Term Loan to retire the former SVB facility in the amount of $4.5 million, including interest and fees, with the remainder to be utilized for working capital purposes. The SVB facility was paid off in full as of December 31, 2013.  As a result of the extinguishment of the SVB credit facility, the Company recorded a loss on extinguishment in the amount of $128,000 primarily related to the unamortized debt discount that is included as part of interest expense in the accompanying consolidated statement of operations for the year end December 31, 2013.
	The Revolver bears interest at the Prime Rate plus 1.75% (totaling 5% at December 30, 2013), and is adjusted every six months for any change in the Prime Rate. In addition to changes in the Prime Rate, the rate can be reduced by up to .50% based on certain EBITDA achievement levels. Under the Revolver, the Company may borrow, repay and re-borrow an amount not to exceed the lesser of $2,500,000 or the total of 80% of eligible billed and unbilled accounts receivable (less the aggregate outstanding on any letters of credit). There were no borrowings under the Revolver as of and for the year ended December 31, 2013. The Term Loan bears interest for the first 6 months at the Prime Rate plus 2.75% (totaling 6% at December 31, 2013), and is adjusted every six months for any change in the Prime Rate. In addition to changes in the Prime Rate, the rate can be reduced by up to .50% based on certain EBITDA achievement levels. The Term Loan may be prepaid without penalty at any time. The Term Loan is interest only for six months followed by 54 principal and interest payments commencing on July 30, 2014 with a balloon payment for any remaining principal balance at maturity.
	The Commerce credit facility is secured by a first priority perfected security interest in substantially all of the Company’s assets and all of the assets of World Energy Securities Corp. The current indebtedness to Massachusetts Capital Resource Company (“MCRC”) is subordinated to the Commerce credit facility. The Loan and Security Agreement contains certain affirmative and negative covenants including a minimum Debt Service Coverage Ratio and financial reporting requirements.
	In conjunction with its former SVB credit facility, the Company issued warrants to SVB to purchase 45,045 shares of the Company’s common stock with an expiration date of October 2, 2019. The Company accounted for the issuance of warrants in accordance with the guidance prescribed in the ASC Topic 470-20, “Accounting for Convertible Debt and Debt Issued with Stock Purchase Warrants” (“ASC 470-20”). In accordance with ASC 470-20, the value of the stock purchase warrants was considered an Original Issue Discount (“OID”) which was required to be amortized over the life of the note as interest expense with a corresponding credit to long-term debt.  The unamortized debt discount at December 31, 2012 was approximately $130,000.  The debt discount was fully amortized at December 31, 2013 in conjunction with the Company’s retirement of the SVB credit facility and included as part of interest expense in the accompanying consolidated statement of operations for the year ended December 31, 2013. The amortization and write-down of unamortized debt discount of approximately $130,000 was included as part of interest expense for the year ended December 31, 2013. For the year ended December 31, 2012, the amortization of debt discount was approximately $10,000, and was included as part of interest expense.
	Subordinated Note
	On October 3, 2012, the Company entered into a Note Purchase Agreement with MCRC, in which the Company entered into an 8-year, $4 million Subordinated Note due 2020 with MCRC (the “MCRC Note”). The MCRC Note bears interest at 10.5% and is interest only for the first four years followed by 48 equal principal payments commencing October 31, 2016. The Company must pay a premium of 3% if it prepays the MCRC Note before October 1, 2014 and a 1% premium if it prepays the MCRC Note before October 1, 2015. The MCRC Note is subordinated to the Company’s credit facility with Commerce Bank and contains a consolidated net earnings available for interest charges to interest charges covenant, as adjusted, of not less than one-to-one that the Company was not in compliance with as of December 31, 2013. Subsequent to December 31, 2013, MCRC waived the non-compliance with this covenant and entered into a new Minimum Fixed Charge Ratio covenant commencing in the first quarter of 2014.  As a result, the MCRC Note has been classified as long-term as of December 31, 2013.
	Aggregate gross principal maturities of debt by year are as follows:

Principles of Consolidation

'

Principles of Consolidation

The Company’s accompanying consolidated financial statements include its wholly-owned subsidiary World Energy Securities Corp. All intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

'

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Accordingly, actual results could differ from these estimates.

The Company’s most judgmental estimates affecting its accompanying consolidated financial statements are those relating to revenue recognition and the estimate of actual energy delivered from the bidder to the lister of such energy; stock-based compensation; the valuation of intangible assets and goodwill; the valuation of contingent consideration; impairment of long-lived assets; warranty liability; and estimates of future taxable income as it relates to the realization of the Company’s net deferred tax assets. The Company regularly evaluates its estimates and assumptions based upon historical experience and various other factors that the Company believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. To the extent actual results differ from those estimates; future results of operations may be affected.

Revenue Recognition

'

Revenue Recognition

Retail Electricity Transactions

The Company earns a monthly commission on energy sales contracted through its online auction platform from each bidder or energy supplier based on the energy usage transacted between the bidder and lister or energy consumer. The Company’s commissions are not based on the retail price for electricity; rather on the amount of energy consumed. Commissions are calculated based on the energy usage transacted between the energy supplier and energy consumer multiplied by the Company’s contractual commission rate. The contractual commission rate is negotiated with the energy consumer on a procurement-by-procurement basis based on energy consumer specific circumstances, including the size of auction, the effort required to organize and run the respective auction and competitive factors, among others. Revenue from commissions is recognized as earned on a monthly basis over the life of each contract as energy is consumed, provided there is persuasive evidence of an arrangement, the sales price is fixed or determinable, collection of the related receivable is reasonably assured, and customer acceptance criteria, if any, has been successfully demonstrated.

The Company records brokerage commissions based on actual usage data obtained from the energy supplier for that accounting period, or to the extent actual usage data is not available, based on the estimated amount of electricity and gas delivered to the energy consumers for that accounting period. The Company develops its estimates on a quarterly basis based on the following criteria:

Payments received prior to the issuance of the consolidated financial statements;

Usage updates from energy suppliers;

Usage data from utilities;

Comparable historical usage data; and

Historical variances to previous estimates.

To the extent usage data cannot be obtained, the Company estimates revenue as follows:

Historical usage data obtained from the energy consumer in conjunction with the execution of the auction;

Geographic/utility usage patterns based on actual data received;

Analysis of prior year usage patterns; and

Specific review of individual energy supplier/location accounts.

In addition, the Company analyzes this estimated data based on overall industry trends including prevailing weather and usage data. Once the actual data is received, the Company adjusts the estimated accounts receivable and revenue to the actual total amount in the period during which the payment is received. Based on management’s current capacity to obtain actual energy usage, the Company currently estimates four to six weeks of revenue at the end of its accounting period. Differences between estimated and actual revenue have been within management’s expectations and have not been material to date.

The Company does not invoice its electricity energy suppliers for monthly commissions earned and, therefore, it classifies a substantial portion of its receivables as “unbilled.” Unbilled accounts receivable represents management’s best estimate of energy provided by the energy suppliers to the energy consumers for a specific completed time period at contracted commission rates and is made up of two components. The first component represents energy usage for which the Company has received actual data from the supplier and/or the utility but for which payment has not been received at the balance sheet date. The majority of the Company’s contractual relationships with energy suppliers require them to supply actual usage data to the Company on a monthly basis and remit payment to the Company based on that usage. The second component represents energy usage for which the Company has not received actual data, but for which it has estimated usage. Commissions paid in advance by certain energy suppliers are recorded as deferred revenue and amortized to commission revenue on a monthly basis on the energy exchanged that month.

Retail Natural Gas Transactions

There are two primary fee components to the Company’s retail natural gas services: transaction fees and management fees. Transaction fees are billed to and paid by the energy supplier awarded business on the platform. These fees are established prior to award and are the same for each supplier. For the majority of the Company’s natural gas transactions, the supplier is billed upon the conclusion of the transaction based on the estimated energy volume transacted for the entire award term multiplied by the transaction fee. Management fees are paid by the Company’s energy consumers and are generally billed on a monthly basis for services rendered based on terms and conditions included in contractual arrangements. While substantially all of the Company’s retail natural gas transactions are accounted for in accordance with this policy, a significant percentage are accounted for as the natural gas is consumed by the customer and recognized as revenue in accordance with the retail electricity transaction revenue recognition methodology described above.

Mid-Market Transactions

The Company earns a monthly commission on energy sales from each energy supplier based on the energy usage transacted between the energy supplier and energy consumer. The commissions are not based on the retail price for electricity but rather on the amount of energy consumed. Commissions are calculated based on the energy usage transacted between the energy supplier and energy consumer multiplied by the Company’s contractual commission rate. Revenue from commissions is recognized as earned over the life of each contract as energy is consumed, provided there is persuasive evidence of an arrangement, the sales price is fixed or determinable, collection of the fee is reasonably assured, and customer acceptance criteria, if any, has been successfully demonstrated. The Company generally recognizes revenue on these transactions when it has received verification from the electricity supplier of the end-users power usage and electricity supplier’s subsequent collection of the fees billed to the end user. The verification is generally accompanied with payment of the agreed upon fee to the Company, at which time the revenue is recognized. Commissions paid in advance are recorded as customer advances and are recognized monthly as commission revenue based on the energy exchanged that month. To the extent the Company does not receive verification of actual energy usage or it cannot reliably estimate what actual energy usage was for a given period, revenue is deferred until usage and collection data is received from the energy supplier. To the extent that the Company does not receive actual usage data from the energy supplier, it will recognize revenue at the end of the contract flow date. In October 2012, the Company acquired Northeast Energy Partners, LP (“NEP”). NEP recognizes revenue monthly as energy flows from the energy supplier to the end user. The Company can reliably estimate actual energy usage based on historical usage data compiled by NEP.

Demand Response Transactions

Demand response transaction fees are recognized when the Company receives confirmation from the demand response provider (“DRP”) that the energy consumer has performed under the applicable Regional Transmission Organization (“RTO”) or Independent Service Operator (“ISO”) program requirements. The energy consumer is either called to perform during an actual curtailment event or is required to demonstrate its ability to perform in a test event during the performance period. For PJM Interconnection (“PJM”), an RTO that coordinates the movement of wholesale electricity in all or parts of 13 states and the District of Columbia, the performance period is June through September in a calendar year. Test results are submitted to PJM by the DRPs and the Company receives confirmation of the energy consumer’s performance in the fourth quarter. DRPs typically pay the Company ratably on a quarterly basis throughout the demand response fiscal (June to May) year. As a result, a portion of the revenue the Company recognizes is reflected as unbilled accounts receivable.

Wholesale and Environmental Commodity Transactions

Wholesale transaction fees are invoiced upon the conclusion of the auction based on a fixed fee. These revenues are not tied to future energy usage and are recognized upon the completion of the online auction. For reverse auctions where the Company’s customers bid for a consumer’s business, the fees are paid by the bidder. For forward auctions where a lister is selling energy products, the fees are typically paid by the lister. While substantially all wholesale transactions are accounted for in this fashion, a small percentage of the Company’s wholesale revenue is accounted for as electricity or gas is delivered, similar to the retail electricity transaction methodology described above.

Environmental commodity transaction fees are accounted for utilizing two primary methods. For regulated allowance programs like the Regional Greenhouse Gas Initiative (“RGGI”), fees are paid by the lister and are recognized as revenue quarterly as auctions are completed and approved. For most other environmental commodity transactions both the lister and the bidder pay the transaction fee and revenue is recognized upon the consummation of the underlying transaction as credits are delivered by the lister and payment is made by the bidder.

Channel Partner Commissions

The Company pays commissions to its channel partners at contractual rates based on monthly energy transactions between energy suppliers and energy consumers. The commission is accrued monthly and charged to sales and marketing expense as revenue is recognized. The Company pays commissions to its salespeople at contractual commission rates based upon cash collections from its customers.

Revenue Estimation

The Company’s estimates in relation to revenue recognition affect revenue and sales and marketing expense as reflected on its consolidated statements of operations, and trade accounts receivable and accrued commission accounts as reflected on its consolidated balance sheets. For any quarterly reporting period, the Company may not have actual usage data for certain energy suppliers and will need to estimate revenue. Revenue is initially recorded based on the energy consumers’ historical usage profile. At the end of each reporting period, the Company adjusts this historical profile to reflect actual usage for the period and estimate usage where actual usage is not available. For the year ended December 31, 2013, the Company estimated usage for approximately 9% of its revenue resulting in a negative 0.3%, or approximately $105,000, adjustment to decrease revenue. This decrease in revenue resulted in an approximate $16,000 decrease in sales and marketing expense related to third party commission expense associated with those revenues. Corresponding adjustments were made to trade accounts receivable and accrued commissions, respectively. A 1% difference between this estimate and actual usage would have an approximate $32,000 effect on the Company’s revenue for the year ended December 31, 2013.

Energy Efficiency Services

The Company’s Energy efficiency services segment is primarily project driven where the Company identifies efficiency measures that energy consumers can implement to reduce their energy usage. The Company presents retrofit opportunities to customers, get approval from them to proceed and submit the proposal to the local utility for pre-approval and determination of available incentives. Once the utility approves funding for the project, the Company installs the equipment, typically new heating, ventilation or air conditioning equipment, or replace lighting fixtures to more efficient models. The Company recognizes revenues for energy efficiency services when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable and collectability is reasonably assured. Due to the short-term nature of projects (typically two to three weeks), the Company utilizes the completed-contract method. The Company also assesses multiple contracts entered into by the same customer in close proximity to determine if the contracts should be combined for revenue recognition purposes. Revenues are recognized based upon factors such as passage of title, installation, payments and customer acceptance.

Cash and Cash Equivalents

'

Cash and Cash Equivalents

The Company considers all highly liquid debt instruments purchased with an original maturity of 90 days or less to be cash equivalents.

Concentration of Credit Risk and Off-Balance Sheet Risk

'

Concentration of Credit Risk and Off-Balance Sheet Risk

Financial instruments that potentially expose the Company to concentrations of credit risk consist principally of cash and trade accounts receivable. The Company has no material off-balance sheet risk such as foreign exchange contracts, option contracts, or other foreign hedging arrangements. The Company places its cash with primarily two institutions, which management believes are of high credit quality. As of December 31, 2013, all of the Company’s cash is held in interest bearing accounts.

The Company provides credit in the form of invoiced and unbilled accounts receivable to customers in the normal course of business. Collateral is not required for trade accounts receivable, but ongoing credit evaluations of customers are performed. While the majority of the Company’s revenue is generated from retail energy transactions where the winning bidder pays a commission to the Company, commission payments for certain auctions can be paid by the lister, customer or a combination of both. Management provides for an allowance for doubtful accounts on a specifically identified basis, as well as through historical experience applied to an aging of accounts, if necessary. Trade accounts receivable are written off when deemed uncollectible. To date write-offs have not been material.

The following represents revenue and trade accounts receivable from bidders exceeding 10% of the total in each category:

In addition to its direct relationship with bidders, the Company also has direct contractual relationships with listers for the online procurement of certain of their energy, demand response or environmental needs. These listers are primarily large businesses and government organizations and do not have a direct creditor relationship with the Company. For the years ended December 31, 2013 and 2012, no energy consumer represented more than 10% individually of the Company’s aggregate revenue.

Inventory

'

Inventory

Inventory is maintained in the Company’s Energy efficiency services segment and consists of prepaid expendables and project materials. Prepaid expendables represents consumable components that are used in project installations and are stated at the lower of cost or market, with cost being determined on a first-in, first-out (FIFO) basis. Historical inventory usage and current trends are considered in estimating both excess and obsolete inventory. To date, there have been no material write-downs of inventory and therefore no allowance for excess or obsolete inventory was recorded at December 31, 2013 and 2012. Project materials represent direct costs incurred on projects-in-process as of each reporting period.

Property and Equipment

Property and equipment is stated at cost. Depreciation is provided on a straight-line basis over the estimated useful lives of the related assets or the life of the related lease, whichever is shorter, which range from 3 to 10 years.

Investment / Convertible Note Receivable

'

Investment / Convertible Note Receivable

In 2010, the Company made a strategic investment in the form of a two-year $650,000 convertible note with Retroficiency, Inc. (“Retroficiency”). The convertible note accrued interest at 9% per annum with principal and interest due at the end of the term on July 22, 2012. It included optional and automatic conversion rights to convert into Retroficiency shares at $0.54 per share and was subject to adjustment in certain circumstances. During the fourth quarter of 2011, Retroficiency executed a qualified financing in the form of Series A Preferred Stock at a price in excess of the Company’s conversion price and all principal and interest amounts outstanding under the convertible note receivable at the time of the financing were converted into Series A Preferred Stock. In March 2012, the Company sold its investment in Retroficiency at a premium to its carrying value. As a result, a gain of approximately $53,000 was recorded as other income in the accompanying consolidated statements of operations for the year ended December 31, 2012.

Other Assets

'

Other Assets

Certain acquired software and significant enhancements to the Company’s software are capitalized in accordance with Accounting Standards Codification (“ASC”) 350-40, “Internal-Use Software” (“ASC 350-40”). Internally developed software costs capitalized in 2013 amounted to $58,500. No internally developed software costs were capitalized in 2012 or 2011. The Company amortized internally developed and purchased software over the estimated useful life of the software (generally three years). During 2013, 2012 and 2011, approximately $2,000, $18,000 and $113,000 were amortized to cost of revenues, respectively. Accumulated amortization was approximately $1,223,000 and $1,221,000 at December 31, 2013 and 2012, respectively. Pre- and post- software implementation and configuration costs have historically been immaterial and charged to cost of revenue as incurred. In addition, $400,000 of certain long term prepaid partner payments are included in other assets at December 31, 2013, and $500,000 was included in the balance at December 31, 2012.

Intangible Assets

'

Intangible Assets

The Company uses assumptions in establishing the initial carrying value, fair value and estimated lives of its intangible assets. The criteria used for these assumptions include management’s estimate of the asset’s continuing ability to generate positive income from operations and positive cash flow in future periods compared to the carrying value of the asset, as well as the strategic significance of any identifiable intangible asset in the Company’s business objectives. If assets are considered impaired, the impairment recognized is the amount by which the carrying value of the assets exceeds the fair value of the assets. Useful lives and related amortization expense are based on an estimate of the period that the assets will generate revenues or otherwise be used by the Company. Factors that would influence the likelihood of a material change in the Company’s reported results include significant changes in the asset’s ability to generate positive cash flow, a significant decline in the economic and competitive environment on which the asset depends and significant changes in the Company’s strategic business objectives.

Intangible assets consist of customer relationships and contracts, purchased technology and other intangibles, and are stated at cost less accumulated amortization. Intangible assets with a finite life are amortized using the straight-line method over their estimated useful lives, which range from one to ten years.

Impairment of Long-Lived and Intangible Assets

'

Impairment of Long-Lived and Intangible Assets

In accordance with ASC 350, “Intangibles – Goodwill and Other” (“ASC 350”), the Company periodically reviews long-lived assets and intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable or that the useful lives of those assets are no longer appropriate. Recoverability of these assets is determined by comparing the forecasted undiscounted net cash flows of the operation to which the assets relate to the carrying amount. No impairment of the Company’s long-lived assets was recorded as no change in circumstances indicated that the carrying value of the assets was not recoverable during the years ended December 31, 2013 and 2012.

Goodwill & Indefinite-Lived Intangible Assets

'

Goodwill & Indefinite-Lived Intangible Assets

The Company uses assumptions in establishing the initial carrying value and fair value of its goodwill and indefinite-lived intangibles. Goodwill represents the excess of the purchase price over the fair value of identifiable net assets of acquired businesses. Indefinite-lived intangibles are intangible assets whose useful lives are indefinite in that their lives extend beyond the foreseeable horizon – that is there is no foreseeable limit on the period of time over which it is expected to contribute to the cash flows of the reporting entity. The Company accounts for these items in accordance with ASC 350, under which goodwill and intangible assets having indefinite lives are not amortized but instead are assigned to reporting units and tested for impairment annually or more frequently if changes in circumstances or the occurrence of events indicate possible impairment.

The Company performs its annual impairment test at the end of the fourth fiscal quarter of each year, or earlier, if indicators of potential impairment exist. This impairment test is performed for each of its segments – Energy procurement and Energy efficiency services – which have been determined to be the Company’s reporting units. The impairment test for goodwill and indefinite-lived intangibles is a three-step process. Step 0 gives entities the option of first performing a qualitative assessment to test for impairment on a reporting-unit-by-reporting-unit basis. If after performing the qualitative assessment, an entity concludes that it is more-likely-than-not (“MLTN”, typically quantified as a likelihood of more than 50%) that the fair value of a reporting unit is less than its carrying amount, then the entity would perform a two-step impairment test. However, if, after applying the qualitative assessment, the entity concludes that it is not MLTN that the fair value is less than the carrying amount, the two step impairment test is not required. Step one consists of a comparison of the fair value of a reporting unit with its carrying amount, including the goodwill allocated to each reporting unit. If the carrying amount is in excess of the fair value, step two requires the excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of the reporting unit’s goodwill to be recorded as an impairment loss. To determine the fair value of each of the reporting units as a whole, the Company uses a discounted cash flow analysis, which requires significant assumptions and estimates about the future operations of each reporting unit. Significant judgments inherent in this analysis include the determination of appropriate discount rates, the amount and timing of expected future cash flows and growth rates. The cash flows employed in the discounted cash flow analyses are based on financial forecasts developed by management. The discount rate assumptions are based on an assessment of the Company’s risk adjusted discount rate, applicable for each reporting unit. In assessing the reasonableness of the determined fair values of the reporting units, the Company evaluates its results against its current market capitalization.

As of December 31, 2013 and 2012, the Company performed a step one analysis on both the energy procurement and energy efficiency services reporting units and determined that their indicated fair values substantially exceeded their carrying values. The Company relied on a weighted average cost of capital of 15.75% and 16.15% for each reporting unit as of December 31, 2013 and 2012, respectively, which takes into consideration certain specific small company premiums. The Company utilized a long-term growth rate of approximately 8% and 3% for the energy procurement and 15% and 20% efficiency services reporting units as of December 31, 2013 and 2012, respectively, and assumed a combined tax rate of 40% for both units and in both years.

As of December 31, 2013, the Company performed a step one analysis on the Company’s indefinite-life intangibles related to its Energy efficiency services segment customer relationships. Indefinite-life was assigned to the Company’s prime contractor relationships with the customer base in the Norwich Public (“Norwich”) and United Illuminated (“UI”) utility regions (“Prime”) and the Company’s relationships with the customer base within the Connecticut, Light and Power, UI and Norwich regions as a subcontractor (“Subcontractor”) at the NES acquisition date. The fair value of both the Prime and Subcontractor relationships exceeded their carrying values. The Company relied on a weighted average cost of capital of 16.6% for the Prime relationship and 15.7% for the subcontractor relationship as of December 31, 2013, which takes into consideration certain specific small company premiums. The Company utilized a long-term growth rate of approximately 10% for both the Prime and Subcontractor relationships and assumed a combined tax rate of 40% for both.  As of December 31, 2012, the Company performed a qualitative assessment of its indefinite-lived intangibles related to its Energy efficiency services segment customer relationships and determined that it was not likely that the fair value of a reporting unit was less than its carrying value.

Deferred Revenue and Customer Advances

Warranty

'

Warranty

The Company’s Energy efficiency services segment provides its customers a one year warranty for all parts and labor in its installation workmanship. The Company has determined primarily from historical information and management’s judgment, that warranty costs are immaterial and no estimate for warranty cost is required at the time revenue is recognized. Should actual warranties differ from the Company’s estimates, an estimated warranty liability would be required.

Income Taxes

'

Income Taxes

In accordance with ASC 740, “Income Taxes” (“ASC 740”), deferred tax assets and liabilities are determined at the end of each period based on the future tax consequences that can be attributed to net operating loss carryforwards, as well as differences between the financial statement carrying amounts of the existing assets and liabilities and their respective tax basis. Deferred income tax expense or credits are based on changes in the asset or liability from period to period. Valuation allowances are provided if, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The realization of deferred tax assets is dependent upon the generation of future taxable income. In assessing the requirement of a valuation allowance, the Company considers past performance, expected future taxable income, and qualitative factors which the Company considers to be appropriate in estimating future taxable income. The Company’s forecast of expected future taxable income is for future periods that can be reasonably estimated. Results that differ materially from current expectations may cause the Company to change its judgment on future taxable income and the necessity of a tax valuation allowance.

The Company has reviewed the tax positions taken, or to be taken, in its tax returns for all tax years currently open to examination by the taxing authority in accordance with ASC 740’s recognition and measurement standards. At December 31, 2013, there are no expected material, aggregate tax effects of differences between tax return positions and the benefits recognized in the Company’s consolidated financial statements. The Company accounts for interest and penalties related to uncertain tax positions as part of its provision for income taxes.

Stock-based Compensation

'

Stock-based Compensation

The Company recognizes the compensation from stock-based awards on a straight-line basis over the requisite service period of the award. Stock-based awards to employees consisted of grants of stock options for the years ended December 31, 2013, 2012 and 2011 and grants of restricted stock for the years ended December 31, 2013 and 2012, respectively. The restrictions on the restricted stock lapse over the vesting period. The vesting period of stock-based awards is determined by the board of directors, and is generally four years for employees.

The Company accounts for transactions in which services are received from non-employees in exchange for equity instruments based on the fair value of such services received or of the equity instruments issued, whichever is more reliably measured. There were no equity instruments granted to non-employees for the year ended December 31, 2013. For the years ended December 31, 2012 and 2011 stock-based awards to non-employees consisted of grants of stock warrants. The vesting period of stock warrants granted ranged from one to seven years.

Leases

'

Leases

Rent under non-cancelable operating leases that include scheduled rent increases are accounted for on a straight-line basis over the lease term.  Allowances and other lease incentives provided by the lessor are amortized on a straight-line basis as a reduction of rent expense.  The difference between straight-line expense and rent paid is recorded as a deferred rent liability in the consolidated balance sheet.

Advertising Expense

'

Advertising Expense

Advertising expense primarily includes promotional expenditures and is expensed as incurred. Advertising expenses incurred were approximately $229,000, $205,000 and $144,000 for the years ended December 31, 2013, 2012 and 2011, respectively.

Comprehensive Income (Loss)

Comprehensive Income (Loss)

ASC 220, “Comprehensive Income” (“ASC 220”), establishes standards for reporting and displaying comprehensive (loss) income and its components in financial statements. Comprehensive (loss) income is defined as the change in stockholders’ equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. The comprehensive (loss) income for all periods presented consisted only of the reported net (loss) income.

Fair Value of Financial Instruments

'

Fair Value of Financial Instruments

The Company’s financial instruments include cash and cash equivalents, accounts receivable, accounts payable, accrued expenses (including contingent consideration) and debt. The carrying amounts for these financial instruments reported in the consolidated balance sheets approximate their fair values.

Fair Value Measurements

'

Fair Value Measurements

The Company follows ASC 820, “Fair Value Measurements and Disclosures” (“ASC 820”), for fair value measurements. ASC 820 defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. The standard provides a consistent definition of fair value, which focuses on an exit price, which is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The standard also prioritizes, within the measurement of fair value, the use of market-based information over entity specific information and establishes a three-level hierarchy for fair value measurements based on the nature of inputs used in the valuation of an asset or liability as of the measurement date.

The hierarchy established under ASC 820 gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3).

Level 1 — Pricing inputs are quoted prices available in active markets for identical investments as of the reporting date. As required by ASC 820-10, the Company does not adjust the quoted price for these investments, even in situations where the Company holds a large position and a sale could reasonably impact the quoted price.

Level 2 — Pricing inputs are quoted prices for similar investments, or inputs that are observable, either directly or indirectly, for substantially the full term through corroboration with observable market data. Level 2 includes investments valued at quoted prices adjusted for legal or contractual restrictions specific to these investments.

Level 3 — Pricing inputs are unobservable for the investment, that is, inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Level 3 includes investments that are supported by little or no market activity.

Segment Reporting

'

Segment Reporting

ASC 280, “Segment Reporting” (“ASC 280”), establishes standards for reporting information about operating segments in financial statements. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision maker is the president and chief executive officer. The Company’s chief operating decision maker reviews the results of operations based on two industry segments: Energy procurement and Energy efficiency services.

Recent Accounting Pronouncements

In July 2013, Accounting Standards Update (“ASU”) 2013-11, "Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists" (“ASU 2013-11”), was issued which defines the presentation requirements of an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the financial statements. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted and retrospective application is permitted but not required. The Company does not expect the application of this ASU to have an impact on its consolidated financial statements.

Summary of Rollforward of Fair Value	'
	The Company determines the fair value of acquisition-related contingent consideration based on assessment of the probability that the Company would be required to make such future payment. Management assigns probabilities to each level of attainment and weights those probabilities to determine the amount to accrue at each reporting period. As the contingent consideration was based on financial or operational performance, management monitors performance against target and estimates future performance based on current forecasts. At December 31, 2013, all performance periods had concluded and calculations were based on actual performance. The final payment related to the NEP contingent consideration was made on December 31, 2013. Total adjustments made were to decrease fair value by $0.7 million. At December 31, 2013, the remaining contingent consideration balance represents management’s estimate of the amount that is expected to be paid to GSE in settlement of all contingent consideration amounts outstanding. The net result was a $0.1 million reduction in accrued contingent consideration. Changes to the fair value of contingent consideration are recorded in general and administrative expense. The following table provides a rollforward of the fair value, as determined by level 3 inputs, of the contingent consideration.
