Summary of Significant Accounting Policies

12 Months Ended

Mar. 31, 2014

Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The consolidated financial statements include the accounts of Orion Energy Systems, Inc. and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation.

Reclassifications

Where appropriate, certain reclassifications were made to prior years' financial statements to conform to the current year presentation.

Use of Estimates

The preparation of financial statements in conformity with Generally Accepted Accounting Principles, or GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during that reporting period. Areas that require the use of significant management estimates include revenue recognition, inventory obsolescence and bad debt reserves, accruals for warranty expenses, income taxes and certain equity transactions. Accordingly, actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers all highly liquid, short-term investments with original maturities of three months or less to be cash equivalents.

Short-Term Investments

The amortized cost and fair value of short-term investments, with gross unrealized gains and losses, as of March 31, 2013 and 2014 were as follows (in thousands):



March 31, 2013
	Amortized Cost		Unrealized Gains		Unrealized Losses		Fair Value		Cash and Cash Equivalents		Short-Term Investments
Money market funds	$	487	$	—	$	—	$	487	$	487	$	—
Bank certificate of deposit	1,021		—		—		1,021		—		1,021
Total	$	1,508	$	—	$	—	$	1,508	$	487	$	1,021

March 31, 2014
	Amortized Cost		Unrealized Gains		Unrealized Losses		Fair Value		Cash and Cash Equivalents		Short-Term Investments
Money market funds	$	488	$	—	$	—	$	488	$	488	$	—
Bank certificate of deposit	470		—		—		470		—		470
Total	$	958	$	—	$	—	$	958	$	488	$	470

As of March 31, 2013 and 2014, the Company’s financial assets described in the table above were measured at cost which approximates fair value due to the short-term nature of the investment (level 1 inputs).

Fair Value of Financial Instruments

The Company’s financial instruments consist of cash, short-term investments, accounts receivable, accounts payable, accrued expenses and other and long-term debt. The carrying amounts of the Company’s financial instruments approximate their respective fair values due to the relatively short-term nature of these instruments, or in the case of long-term, because of the interest rates currently available to the Company for similar obligations. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. GAAP describes a fair value hierarchy based on the following three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value:

Level 1 — Valuations are based on unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 — Valuations are based on quoted prices for similar assets or liabilities in active markets, or quoted prices in markets that are not active for which significant inputs are observable, either directly or indirectly.

Level 3 — Valuations are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. Inputs reflect management’s best estimate of what market participants would use in valuing the asset or liability at the measurement date.

Accounts Receivable

Substantially all of the Company’s accounts receivable are due from companies in the commercial, industrial and agricultural industries, as well as wholesalers. Credit is extended based on an evaluation of a customer’s financial condition. Generally, collateral is not required for end users; however, the payment of certain trade accounts receivable from wholesalers is secured by irrevocable standby letters of credit and/or guarantees. Accounts receivable are generally due within 30-60 days. Accounts receivable are stated at the amount the Company expects to collect from outstanding balances. The Company provides for probable uncollectible amounts through a charge to earnings and a credit to an allowance for doubtful accounts based on its assessment of the current status of individual accounts. Balances that are still outstanding after the Company has used reasonable collection efforts are written off through a charge to the allowance for doubtful accounts and a credit to accounts receivable.

Financing Receivables

The Company considers its lease balances included in consolidated current and long-term accounts receivable from its Orion Throughput Agreement, or OTA, sales-type leases to be financing receivables. Additional disclosures on the credit quality of the Company’s financing receivables are as follows:

Age Analysis as of March 31, 2013 (in thousands):

Total net sales-type leases	$	3,726		$	134		$	61		$	195		$	3,921

Allowance for Credit Losses on Financing Receivables

The Company’s allowance for credit losses is based on management’s assessment of the collectability of customer accounts. A considerable amount of judgment is required in order to make this assessment including a detailed analysis of the aging of the lease receivables and the current credit worthiness of the Company's customers and an analysis of historical bad debts and other adjustments. If there is a deterioration of a major customer’s credit worthiness or actual defaults are higher than historical experience, the estimate of the recoverability of amounts due could be adversely affected. The Company reviews in detail the allowance for doubtful accounts on a quarterly basis and adjusts the allowance estimate to reflect actual portfolio performance and any changes in future portfolio performance expectations. The Company believes that there is no impairment of the receivables for the sales-type leases. The Company’s provision for write-offs and credit losses against the OTA sales-type lease receivable balances in fiscal 2013 and fiscal 2014, respectively, was as follows:



		Balance at beginning of period		Provisions charged to expense		Write offs and other		Balance at end of period
March 31,		(in Thousands)
2013	Allowance for Doubtful Accounts on financing receivables	$	24	$	50	$	—	$	74
2014	Allowance for Doubtful Accounts on financing receivables	$	74	$	96	$	76	$	94

Inventories

Inventories consist of raw materials and components, such as ballasts, metal sheet and coil stock and molded parts; work in process inventories, such as frames and reflectors; and finished goods, including completed fixtures and systems, and wireless energy management systems and accessories, such as lamps, meters and power supplies. All inventories are stated at the lower of cost or market value with cost determined using the first-in, first-out (FIFO) method. The Company reduces the carrying value of its inventories for differences between the cost and estimated net realizable value, taking into consideration usage in the preceding 9 to 24 months, expected demand, and other information indicating obsolescence. The Company records as a charge to cost of product revenue the amount required to reduce the carrying value of inventory to net realizable value. As of March 31, 2013 and 2014, the Company had inventory obsolescence reserves of $2.3 million and $2.5 million, respectively.

Costs associated with the procurement and warehousing of inventories, such as inbound freight charges and purchasing and receiving costs, are also included in cost of product revenue.

Inventories were comprised of the following (in thousands):



	March 31, 2013		March 31, 2014
Raw materials and components	$	7,290	$	6,894
Work in process	846		880
Finished goods	6,177		4,016
	$	14,313	$	11,790

Deferred Contract Costs

Deferred contract costs consist primarily of the costs of products delivered, and services performed, that are subject to additional performance obligations or customer acceptance. These deferred contract costs are expensed at the time the related revenue is recognized. Deferred costs amounted to $2.1 million and $0.7 million as of March 31, 2013 and March 31, 2014, respectively.

Prepaid Expenses and Other Current Assets

Prepaid expenses and other current assets consist primarily of prepaid insurance premiums, prepaid license fees, purchase deposits, advance payments to contractors, unbilled revenue, prepaid taxes and miscellaneous receivables. Prepaid expenses and other current assets includes $1.6 million and $2.8 million of unbilled accounts receivable as of March 31, 2013 and March 31, 2014, respectively. Prepaid expenses and other current assets also includes $1.0 million of assets held for sale as of March 31, 2014. See Note K "Subsequent Events" for further discussion.

Property and Equipment

Property and equipment are stated at cost. Expenditures for additions and improvements are capitalized, while replacements, maintenance and repairs which do not improve or extend the lives of the respective assets are expensed as incurred. Properties sold, or otherwise disposed of, are removed from the property accounts, with gains or losses on disposal credited or charged to income from operations.

The Company periodically reviews the carrying values of property and equipment for impairment in accordance with ASC 360, Property, Plant and Equipment, if events or changes in circumstances indicate that the assets may be impaired. The estimated future undiscounted cash flows expected to result from the use of the assets and their eventual disposition are compared to the assets’ carrying amount to determine if a write down to market value is required. No write downs were recorded in fiscal 2012 or 2013. In fiscal 2014, an impairment charge of $0.2 million was recorded.

Property and equipment were comprised of the following (in thousands):



	March 31, 2013			March 31, 2014
Land and land improvements	$	1,562		$	1,480
Buildings	15,918			14,405
Furniture, fixtures and office equipment	11,995			10,713
Leasehold improvements	58			46
Equipment leased to customers under Power Purchase Agreements	4,997			4,997
Plant equipment	10,620			10,103
Construction in progress	91			60
	45,241			41,804
Less: accumulated depreciation and amortization	(17,294		)	(18,669		)
Net property and equipment	$	27,947		$	23,135

The Company has no equipment under capital leases.

Depreciation is provided over the estimated useful lives of the respective assets, using the straight-line method. The Company recorded depreciation expense of $4.0 million, $4.3 million and $3.8 million for the years ended March 31, 2012, 2013 and 2014, respectively. Depreciable lives by asset category are as follows:



Land improvements	10-15 years
Buildings and building improvements	3-39 years
Leasehold improvements	Shorter of asset life or life of lease
Furniture, fixtures and office equipment	2-10 years
Equipment leased to customers under Power Purchase Agreements	20 years
Plant equipment	3-10 years

No interest was capitalized for construction in progress during fiscal 2013 or fiscal 2014.

Goodwill and Other Intangible Assets

The costs of specifically identifiable intangible assets that do not have an indefinite life are amortized over their estimated useful lives. Goodwill and intangible assets with indefinite lives are not amortized. Goodwill and intangible assets with indefinite lives are reviewed for impairment annually, as of January 1, or more frequently if impairment indicators arise. Amortizable intangible assets are amortized over their estimated economic useful life to reflect the pattern of economic benefits consumed based upon the following lives and methods:



Patents	10-17 years	Straight-line
Licenses	7-13 years	Straight-line
Customer relationships	5-8 years	Accelerated based upon the pattern of economic benefits consumed
Developed technology	8 years	Accelerated based upon the pattern of economic benefits consumed
Non-competition agreements	5 years	Straight-line

Indefinite lived intangible assets are evaluated for potential impairment whenever events or circumstances indicate that the carrying value may not be recoverable based primarily upon whether expected future undiscounted cash flows are sufficient to support the asset recovery. If the actual useful life of the asset is shorter than the estimated life estimated by us, the asset may be deemed to be impaired and accordingly a write-down of the value of the asset determined by a discounted cash flow analysis or shorter amortization period may be required.

The change in the carrying value of goodwill during fiscal 2014 was as follows (in thousands):



Balance at March 31, 2013	$	—
Acquisition of Harris	4,409
Balance at March 31, 2014	$	4,409

The components of, and changes in, the carrying amount of other intangible assets were as follows (in thousands):



	March 31, 2013					March 31, 2014
	Gross Carrying Amount		Accumulated Amortization			Gross Carrying Amount		Accumulated Amortization

The Company’s management periodically reviews the carrying value of intangible assets for impairment. Write-offs recorded in fiscal 2012, 2013 and 2014 were $19,000, $0 and $45,000, respectively.

Long-Term Receivables

The Company records a long-term receivable for the non-current portion of its sales-type capital lease OTA contracts. The receivable is recorded at the net present value of the future cash flows from scheduled customer payments. The Company uses the implied cost of capital from each individual contract as the discount rate.

Also included in other long-term receivables are amounts due from a third party finance company to which the Company has sold, without recourse, the future cash flows from OTAs entered into with customers. Such receivables are recorded at the present value of the future cash flows discounted between 8.8% and 11.0%. As of March 31, 2014, the following amounts were due from the third party finance company in future periods (in thousands):



Fiscal 2015	$	955
Fiscal 2016	309
Fiscal 2017	9
Total gross financed receivable	1,273
Less: amount above to be collected during the next 12 months	(955		)
Less: amount representing interest	(107		)
Total net long-term receivable	$	211

Long-Term Inventories

The Company records long-term inventory for the non-current portion of its wireless controls inventory. The inventories are stated at the lower of cost or market value with cost determined using the FIFO method.

Other Long-Term Assets

Other long-term assets include long-term security deposits, prepaid licensing costs, deferred costs for a long-term contract, and deferred financing costs. Other long-term assets include $58,000 and $33,000 of deferred financing costs as of March 31, 2013 and March 31, 2014, respectively. Deferred financing costs related to debt issuances are amortized to interest expense over the life of the related debt issue (1 to 10 years). For the years ended March 31, 2012, 2013 and 2014, the amortization was $52,000, $42,000 and $40,000, respectively.

Accrued Expenses and Other

Accrued expenses include warranty accruals, accrued wages and benefits, accrued vacation, accrued legal costs, accrued commissions, customer deposits, accrued acquisition liabilities, accrued project costs, sales tax payable and other various unpaid expenses. Accrued expenses include $1.3 million and $0.0 million of accrued reorganization and settlement costs as of March 31, 2013 and March 31, 2014, respectively; and $0.7 million and $1.0 million of accrued project costs as of March 31, 2013 and March 31, 2014, respectively.

The Company generally offers a limited warranty of one year on its lighting products in addition to those standard warranties offered by major original equipment component manufacturers. The manufacturers’ warranties cover lamps and ballasts, which are significant components in the Company’s lighting products. Included in other long-term liabilities is $0.1 million for warranty reserves related to solar operating systems.

Changes in the Company’s warranty accrual were as follows (in thousands):



	March 31,
	2013			2014
Beginning of year	$	84		$	284
Provision to product cost of revenue	402			300
Charges	(202		)	(321		)

Incentive Compensation

The Company’s compensation committee approved an Executive Fiscal Year 2012 Annual Cash Incentive Program under its 2004 Stock and Incentive Awards Plan which became effective as of May 21, 2011. The plan provided for performance based stock option awards ranging in fair value from 13-15% of the fiscal 2012 base salaries of the Company’s named executive officers. The range of fiscal 2012 financial performance-based bonus guidelines under the approved plan began if the Company achieved all of the following: a minimum of $115.0 million in revenue, a minimum of $4.9 million in net income and a minimum of $4.9 million in free cash flow. Free cash flow was defined as cash flow from operations less cash flow used for the purchase of property, plant and equipment. Additionally, if the Company’s performance was greater than 120% of the targets, a cash performance bonus payment was earned that would range from 12-14% of the fiscal 2012 base salaries. Based upon the results for the year ended March 31, 2012, the Company did not accrue any expense related to this plan.

The Company’s compensation committee approved an Executive Fiscal Year 2013 Annual Cash Incentive Program under its 2004 Stock and Incentive Awards Plan which became effective as of June 14, 2012. The plan provided for performance and discretionary cash bonus payments ranging from 25-100% of the fiscal 2013 base salaries of the Company’s named executive officers and other key employees. The plan provided for bonuses to be paid out on the basis of the achievement in fiscal 2013 of (i) target revenue of $119 million and/or (ii) target net income of $3.7 million. Revenue and net income were selected as the performance measures for the cash bonus program because they were viewed as the most critical elements to increasing the value of the Company's common stock and, therefore, to the Company's enterprise value. The compensation committee established a target bonus as a percentage of base salary for each of the named executive officers. If the Company achieved 90% of either or both the revenue and net income targets ($107 million in revenue or $3.33 million in net income), then the named executive officers would have received 50% of their target bonus for that element. If either or both of the target revenue or net income were exceeded, the named executive officers would be eligible to earn up to two times their target bonus for that element based on a sliding scale of up to 150% of the target revenue or net income. As described below, this plan was superseded by a new plan in November 2012, and, therefore, the Company did not accrue any expense related to this plan.

Effective November 9, 2012, the Company’s Compensation Committee approved a new incentive cash bonus program for the second half of fiscal 2013 in replacement of the then existing fiscal 2013 incentive bonus program described above. The new incentive cash bonus program provided a cash bonus opportunity to named executive officers and other key employees based on the Company’s relative achievement, in the second half of fiscal 2013, of target operating income (before bonuses and other extraordinary or unusual items) and target cost containment initiatives. Under the new program, 50% of the target bonus payments were based on the Company’s relative achievement of its cost containment target of $1.48 million for the second half of fiscal 2013. For every $1.00 of cost containment achieved, a bonus pool of $0.167 would be earned, up to a maximum total bonus pool of $247,000 for all employees. The other 50% of the target bonus payments would be based on the Company achieving operating income (before bonuses and other extraordinary or unusual items) of $500,000 for the second half of fiscal 2013. For every $1.00 of operating profit achieved, a bonus pool of $0.50 would be earned, up to a maximum total bonus pool of $247,000 for all employees. Based upon the results for the year ended March 31, 2013, the Company accrued the maximum expense related to this plan.

The Company’s compensation committee approved an Executive Fiscal Year 2014 Annual Cash Incentive Program under its 2004 Stock and Incentive Awards Plan which became effective as of May 13, 2013. The plan provided for performance cash bonus payments ranging from 35-100% of the fiscal 2014 base salaries of the Company’s named executive officers and other key employees. The plan provided for bonuses to be paid out on the basis of the achievement in fiscal 2014 of at least (i) $2.0 million of profit before taxes and (ii) revenue of at least $88.0 million. Based upon the results for the year ended March 31, 2014, the Company did not accrue any expense related to this plan.

Revenue Recognition

Revenue is recognized on the sales of our lighting and related energy efficiency systems and products when the following four criteria are met:


1.	persuasive evidence of an arrangement exists;


2.	delivery has occurred and title has passed to the customer;


3.	the sales price is fixed and determinable and no further obligation exists; and


4.	collectability is reasonably assured.

These four criteria are met for the Company’s product-only revenue upon delivery of the product and title passing to the customer. At that time, the Company provides for estimated costs that may be incurred for product warranties and sales returns. Revenues are presented net of sales tax and other sales related taxes.

For sales of the Company’s lighting and energy management technologies, consisting of multiple elements of revenue, such as a combination of product sales and services, the Company determines revenue by allocating the total contract revenue to each element based on their relative selling prices in accordance with ASC 605-25, Revenue Recognition - Multiple Element Arrangements. In such circumstances, the Company uses a hierarchy to determine the selling price to be used for allocating revenue to deliverables: (1) vendor-specific objective evidence (VSOE) of fair value, if available, (2) third-party evidence (TPE) of selling price if VSOE is not available, and (3) best estimate of the selling price if neither VSOE nor TPE is available (a description as to how the Company determined estimated selling price is provided below).

The nature of the Company’s multiple element arrangements for the sale of its lighting and energy management technologies is similar to a construction project, with materials being delivered and contracting and project management activities occurring according to an installation schedule. The significant deliverables include the shipment of products and related transfer of title and the installation.

To determine the selling price in multiple-element arrangements, the Company establishes the selling price for its HIF lighting and energy management system products using management's best estimate of the selling price, as VSOE or TPE does not exist. Product revenue is recognized when products are shipped. For product revenue, management's best estimate of selling price is determined using a cost plus gross profit margin method. In addition, the Company records in service revenue the selling price for its installation and recycling services using management’s best estimate of selling price, as VSOE or TPE does not exist. Service revenue is recognized when services are completed and customer acceptance has been received. Recycling services provided in connection with installation entail the disposal of the customer’s legacy lighting fixtures. The Company’s service revenues, other than for installation and recycling that are completed prior to delivery of the product, are included in product revenue using management’s best estimate of selling price, as VSOE or TPE does not exist. These services include comprehensive site assessment, site field verification, utility incentive and government subsidy management, engineering design, and project management. For these services, along with the Company's installation and recycling services, under a multiple-element arrangement, management’s best estimate of selling price is determined by considering several external and internal factors including, but not limited to, economic conditions and trends, customer demand, pricing practices, margin objectives, competition, geographies in which the Company offers its products and services and internal costs. The determination of estimated selling price is made through consultation with and approval by management, taking into account all of the preceding factors.

For sales of solar photovoltaic systems, which are governed by customer contracts that require the Company to deliver functioning solar power systems and are generally completed within three to 15 months from the start of construction, the Company recognizes revenue from fixed price construction contracts using the percentage-of-completion method in accordance with ASC 605-35, Construction-Type and Production-Type Contracts. Under this method, revenue arising from fixed price construction contracts is recognized as work is performed based upon the percentage of incurred costs to estimated total forecasted costs. The Company has determined that the appropriate method of measuring progress on these sales is measured by the percentage of costs incurred to date of the total estimated costs for each contract as materials are installed. The percentage-of-completion method requires revenue recognition from the delivery of products to be deferred and the cost of such products to be capitalized as a deferred cost and current asset on the balance sheet. The Company performs periodic evaluations of the progress of the installation of the solar photovoltaic systems using actual costs incurred over total estimated costs to complete a project. Provisions for estimated losses on uncompleted contracts, if any, are recognized in the period in which the loss first becomes probable and reasonably estimable.

The Company offers a financing program, called an Orion Throughput Agreement, or OTA, for a customer’s lease of the Company’s energy management systems. The OTA is structured as a sales-type lease and upon successful installation of the system and customer acknowledgment that the system is operating as specified, revenue is recognized at the Company’s net investment in the lease, which typically is the net present value of the future cash flows.

The Company offers a financing program, called a power purchase agreement, or PPA, for the Company’s renewable energy product offerings. A PPA is a supply side agreement for the generation of electricity and subsequent sale to the end user. Upon the customer’s acknowledgment that the system is operating as specified, product revenue is recognized on a monthly basis over the life of the PPA contract, which is typically in excess of 10 years.

Deferred revenue relates to advance customer billings, investment tax grants received related to PPAs and a separate obligation to provide maintenance on OTAs and is classified as a liability on the Consolidated Balance Sheet. The fair value of the maintenance is readily determinable based upon pricing from third-party vendors. Deferred revenue related to maintenance services is recognized when the services are delivered, which occurs in excess of a year after the original OTA contract is executed.

Shipping and Handling Costs

The Company records costs incurred in connection with shipping and handling of products as cost of product revenue. Amounts billed to customers in connection with these costs are included in product revenue.

Advertising

Advertising costs of $117,000, $111,000 and $28,000 for fiscal 2012, 2013 and 2014, respectively, were charged to operations as incurred.

Research and Development

The Company expenses research and development costs as incurred.

Income Taxes

The Company recognizes deferred tax assets and liabilities for the future tax consequences of temporary differences between financial reporting and income tax basis of assets and liabilities, measured using the enacted tax rates and laws expected to be in effect when the temporary differences reverse. Deferred income taxes also arise from the future tax benefits of operating loss and tax credit carryforwards. A valuation allowance is established when management determines that it is more likely than not that all or a portion of a deferred tax asset will not be realized. For the fiscal year ended March 31, 2014, the Company recorded a valuation allowance of $0.8 million against its deferred tax assets.

ASC 740, Income Taxes, also prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination. The Company has classified the amounts recorded for uncertain tax benefits in the balance sheet as other liabilities (non-current) to the extent that payment is not anticipated within one year. The Company recognizes penalties and interest related to uncertain tax liabilities in income tax expense. Penalties and interest are immaterial and are included in the unrecognized tax benefits.

Deferred tax benefits have not been recognized for income tax effects resulting from the exercise of non-qualified stock options. These benefits will be recognized in the period in which the benefits are realized as a reduction in taxes payable and an increase in additional paid-in capital. Realized tax benefits (expense) from the exercise of stock options were $989,000, $70,000 and $13,000 for the fiscal years 2012, 2013 and 2014, respectively.

Stock Option Plans

The Company’s share-based payments to employees are measured at fair value and are recognized in earnings, net of estimated forfeitures, on a straight-line basis over the requisite service period.

Cash flows from the exercise of stock options resulting from tax benefits in excess of recognized cumulative compensation costs (excess tax benefits) are classified as financing cash flows. For the years ended March 31, 2012, 2013 and 2014, $989,000, $70,000 and $13,000, respectively, of such excess tax benefits were classified as financing cash flows.

The Company uses the Black-Scholes option-pricing model. The Company calculates volatility based upon the historical market price of its common stock. The risk-free interest rate is the rate available as of the option date on zero-coupon U.S. Government issues with a remaining term equal to the expected term of the option. The expected term is based upon the vesting term of the Company’s options and expected exercise behavior. The Company has not paid dividends in the past and does not plan to pay any dividends in the foreseeable future. The Company estimates its forfeiture rate of unvested stock awards based on historical experience.

The fair value of each option grant in fiscal 2012, 2013 and 2014 was determined using the assumptions in the following table:



	Fiscal Year Ended March 31,
	2012		2013		2014
Weighted average expected term	5.7 years		5.5 years		4.1 years
Risk-free interest rate	1.5	%	0.8	%	0.8	%
Expected volatility	70.0	%	72.5 - 74.4%		73.3	%
Expected forfeiture rate	15.1	%	21.4	%	20.3	%

Net Income (Loss) per Common Share

Basic net income (loss) per common share is computed by dividing net income (loss) attributable to common shareholders by the weighted-average number of common shares outstanding for the period and does not consider common stock equivalents.

Diluted net income (loss) per common share reflects the dilution that would occur if warrants and stock options were exercised and restricted shares vested. In the computation of diluted net income (loss) per common share, the Company uses the “treasury stock” method for outstanding options, warrants and restricted shares. Diluted net loss per common share is the same as basic net loss per common share for the years ended March 31, 2013 and March 31, 2014, because the effects of potentially dilutive securities are anti-dilutive. The effect of net income (loss) per common share is calculated based upon the following shares (in thousands except share amounts):



	Fiscal Year Ended March 31,
	2012		2013			2014
Numerator:
Net income (loss) (in thousands)	$	483	$	(10,399	)	$	(6,199	)
Denominator:
Weighted-average common shares outstanding	22,953,037		20,996,625			20,987,964
Weighted-average effect of assumed conversion of stock options and warrants	433,488		—			—
Weighted-average common shares and share equivalents outstanding	23,386,525		20,996,625			20,987,964

Basic	$	0.02	$	(0.50	)	$	(0.30	)
Diluted	$	0.02	$	(0.50	)	$	(0.30	)

The following table indicates the number of potentially dilutive securities as of the end of each period:



	March 31,
	2012	2013	2014
Common stock options	3,697,633	3,312,523	2,716,317
Restricted shares	—	105,000	539,204
Common stock warrants	38,980	38,980	38,980
Total	3,736,613	3,456,503	3,294,501

Concentration of Credit Risk and Other Risks and Uncertainties

The Company’s cash is deposited with five financial institutions. At times, deposits in these institutions exceed the amount of insurance provided on such deposits. The Company has not experienced any losses in such accounts and believes that it is not exposed to any significant risk on these balances.

The Company previously depended on one supplier for a number of components necessary for its products, including ballasts and lamps. Purchases from this supplier accounted for 14% of total cost of revenue in fiscal 2012. Currently, the Company has been able to obtain these components from multiple suppliers. For fiscal 2013 and 2014, no supplier accounted for more than 10% of total cost of revenue.

In fiscal 2012 and 2013, there were no customers who individually accounted for greater than 10% of revenue. In fiscal 2014, one customer accounted for 23% of revenue.

As of March 31, 2013 and March 31, 2014, no customers accounted for more than 10% of accounts receivable.

Recent Accounting Pronouncements

In July 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2013-11 ("ASU 2013-11"), “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 requires an entity to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the financial statements as a reduction to the deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The provisions of ASU 2013-11 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The Company is currently evaluating the impact of ASU 2013-11.

In May 2014, FASB issued ASU 2014-09, "Revenue from Contracts with Customers." This ASU is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of good or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. This ASU is effective for annual reporting periods beginning after December 15, 2016 and early adoption is not permitted. Accordingly, the Company will adopt this ASU on April 1, 2017. Companies may use either a full retrospective or modified retrospective approach to adopt this ASU and management is currently evaluating which transition approach to use. The Company is currently evaluating the impact of ASU 2014-09.

ACQUISITION

NOTE C — ACQUISITION

On July 1, 2013, the Company acquired all of the equity interests of Harris Manufacturing, Inc. and Harris LED, LLC(collectively, "Harris"). Harris was a Florida-based lighting company which engineered, designed, sourced and manufactured energy efficient lighting systems, including fluorescent and LED lighting solutions, and day-lighting products.

The acquisition of Harris expanded the Company's product lines, including a patent pending LED lighting product designed for commercial office buildings, increased its sales force and provided growth opportunities into markets where the Company had previously not had a strong presence, specifically, new construction, retail store fronts, commercial office and government.

The acquisition was consummated pursuant to a Stock and Unit Purchase Agreement, dated as of May 22, 2013 ("Purchase Agreement"), by and among Harris, the shareholders and members of Harris ("Harris Shareholders"), and the Company. The acquisition consideration paid to the Harris Shareholders was valued under the Purchase Agreement at an aggregate of $10.0 million, plus an adjustment of approximately $0.2 million to reflect the Company's acquisition of net working capital in excess of a targeted amount, plus an additional $0.6 million for the contingent consideration earn-out value assigned to non-employee Harris shareholders. The aggregate acquisition consideration was paid through a combination of $5.0 million in cash, $3.1 million in a three-year unsecured subordinated promissory note and the issuance of 856,997 shares of unregistered Company common stock. For purposes of the acquisition and the acquisition consideration, the shares of common stock issued in the acquisition of Harris were valued at $2.33 per share, which was the average closing share price as reported on the NYSE MKT for the 45 trading days preceding and the 22 trading days following the execution of the Purchase Agreement. For purposes of applying the purchase accounting provisions of ASC 805, Business Combinations, the shares of common stock issued in the acquisition were valued at $2.41 per share, which was the closing sale price of the Company's common stock as reported on the NYSE MKT on the July 1, 2013, date of acquisition.

On October 21, 2013, the Company executed a letter agreement amending the Purchase Agreement. The letter agreement established a fixed future consideration of $1.4 million for the previously existing earn-out component of the Purchase Agreement and eliminated the requirement that certain revenue targets must be achieved. Under the letter agreement, on January 2, 2014, the Company issued $0.6 million, or 83,943 shares, of the Company's unregistered common stock. The fixed consideration was determined based upon the existing share calculation at a fair value of $3.80 per common share. On January 2, 2015, the Company will pay $0.8 million in cash to settle all outstanding obligations related to the earn-out component of the Purchase Agreement.

Total revenues and pre-tax loss from Harris since the date of acquisition included in the accompanying consolidated statements of income for the year ended March 31, 2014 were $9.4 million and $(0.5) million, respectively. Included in the $0.5 million loss is $0.6 million of expense for intangible amortization and $0.3 million of expense for compensation related to deferred consideration. The Company incurred $0.5 million in acquisition and integration related costs for Harris during the year ended March 31, 2014, which included contingent consideration, legal, accounting and other integration related expenses.

The Purchase Agreement contained customary representations and warranties, as well as indemnification obligations, and limitations thereon, by the Company and the Harris Shareholders.

The following table summarizes the consideration paid to the Harris Shareholders and the preliminary fair value allocation of the purchase price (in thousands):



Consideration paid to Harris Shareholders:
Cash	$	5,000
Seller provided debt	3,124
Shares of Company common stock	2,065
Contingent consideration arrangement	612
Total consideration paid	$	10,801

Cash and cash equivalents	$	8
Accounts receivable, net	2,215
Inventories	1,633
Other current assets	86
Property, plant and equipment	117
Deferred tax asset	141
Identifiable intangible assets:
Customer relationships	3,600
Non-competition agreement	100
Developed technology	900
Trade name and trademarks	1,900
Accounts payable	(1,519		)
Deferred tax liabilities	(2,263		)
Accrued and other liabilities	(526		)
Total identifiable net assets	6,392
Goodwill	4,409
	$	10,801

Prior to the amendment discussed above, the contingent consideration arrangement required the Company to pay the Harris Shareholders up to $1.0 million in unregistered shares of the Company's common stock upon Harris' achievement of certain revenue milestones in calendar year 2013 and/or 2014, and, in the case of certain Harris Shareholders who became employees of the Company, their continued employment by the Company. The potential undiscounted amount of all future payments that the Company could have been required to make under the contingent consideration arrangement was between $0 and $1.0 million. The Company recorded $0.6 million for the non-employee Harris Shareholder portion of the contingent consideration liability on the acquisition date. Total contingent consideration of $0.5 million for employee Harris Shareholders will be recorded as compensation expense through the end of calendar 2014. During the year ended March 31, 2014, the Company expensed $0.3 million in compensation expense.

As part of the preliminary purchase price allocation, the Company determined that the separately identifiable intangible assets acquired consisted of customer relationships, developed technology, trademarks and trade names, and non-competition agreements. The fair value of the acquired identifiable intangible assets and the goodwill in the table above are provisional pending completion of the final valuations for those assets. All of the intangible asset value was assigned to the Company's Energy Management segment.

The separately identifiable intangible assets acquired that do not have an indefinite life are amortized over their estimated economic useful life to reflect the pattern of economic benefits consumed based upon the following lives and methods:



Customer relationships	5-8 years	Accelerated based upon the pattern of economic benefits consumed
Developed technology	8 years	Accelerated based upon the pattern of economic benefits consumed
Non-competition agreements	5 years	Straight-line
Trade name and trademarks	N/A	Indefinite life

The Company used the income approach to value the customer relationships, developed technology and non-competition agreements. This approach calculates the fair value by discounting the forecasted after-tax cash flows for each intangible asset back to a present value at an appropriate risk-adjusted rate of return. The data for these analyses was the cash flow estimates used to price the transaction. Fair value estimates are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions.

In estimating the useful lives of the acquired assets, the Company considered ASC 350-30-35, General Intangibles Other Than Goodwill, and reviewed the following factors: the expected use by the combined company of the assets acquired, the expected useful life of another asset (or group of assets) related to the acquired assets, legal, regulatory or other contractual provisions that may limit the useful life of an acquired asset, the effects of obsolescence, demand, competition and other economic factors, and the level of maintenance expenditures required to obtain the expected future cash flows from the assets. The Company will amortize these intangible assets over their estimated economic useful lives.

The goodwill of $4.4 million arising from the Harris acquisition consists largely of the synergies and economies of scale expected from combining operations, and, to a lesser extent, the assembled workforce of Harris. All of the goodwill was assigned to the Company's Energy Management segment. None of the acquired goodwill is expected to be deductible for tax purposes.

The following unaudited pro forma condensed combined results of operations for the years ended March 31, 2013 and 2014, respectively, are based on the historical financial statements of the Company and Harris giving effect to the business combination as if it had occurred at the beginning of the period presented. Therefore, this pro forma data has been adjusted to include amortization of purchased intangible assets and interest on the promissory note delivered as part of the purchase price during the entire applicable periods. Additionally, the tax benefit of $2.3 million recorded during the year ended March 31, 2014 was eliminated and the tax benefit was recorded during the year ended March 31, 2013. This data is not necessarily indicative of the results of operations that would have been generated if the transaction had occurred at the beginning of the respective periods. Moreover, this data is not intended to be indicative of future results of operations (in thousands, other than per share data).



	Acquisition of Harris Pro Forma Results of Operations
	Fiscal Year Ended March 31,
	2013		2014
Revenue	102,198		92,868
Net loss available to common shareholders	(7,489	)	(9,111	)
Loss per share:
Basic	(0.36	)	(0.43	)
Diluted	(0.36	)	(0.43	)

The supplemental pro forma results above exclude any benefits that may result from the acquisition due to synergies that are expected to be derived from the elimination of any duplicative costs. In addition, the pro forma results for the year ended March 31, 2014 was adjusted to exclude non-recurring aggregate acquisition-related costs of $0.2 million that were incurred in 2013.

Revolving Credit Agreement

The Company has an amended credit agreement (Credit Agreement) with JP Morgan Chase Bank, N.A. (JP Morgan). The Credit Agreement provides for a revolving credit facility (Credit Facility) that matures on August 30, 2014. Borrowings under the Credit Facility are limited to $15.0 million, subject to a borrowing base requirement when the outstanding principal balance of loans under the Credit Facility is greater than $5.0 million. Such commitment includes a $2.0 million sublimit for the issuance of letters of credit. As of March 31, 2014, the Company had no outstanding letters of credit. There were no loans outstanding under the Credit Agreement as of March 31, 2013 or March 31, 2014. In August 2013, the Company completed an additional amendment to extend the maturity date of the Credit Agreement to August 30, 2014, and made certain changes to the financial covenants, which are described below.

The Credit Agreement requires the Company to maintain (i) a ratio of total liabilities to tangible net worth not to exceed 0.50 to 1.00 as of the last day of any fiscal quarter, (ii) average daily unencumbered liquidity of at least $20.0 million during each period of three consecutive business days, (iii) a debt service coverage ratio of greater than 1.25 to 1.00 as of the last day of any fiscal quarter and (iv) a funded debt to EBITDA ratio of less than 2.5 to 1.0 as of the last day of any fiscal quarter. The Credit Agreement also contains certain restrictions on the ability of the Company to make capital or lease expenditures over prescribed limits, incur additional indebtedness, consolidate or merge, guarantee obligations of third parties, make loans or advances, declare or pay any dividend or distribution on its stock, redeem or repurchase shares of its stock or pledge assets. The Company was not in compliance with its debt service coverage ratio and its funded debt to earnings before interest, taxes, depreciation and amortization, or EBITDA, covenants in the Credit Agreement as of March 31, 2014. The Company received a waiver from JP Morgan for the covenant defaults.

The Credit Agreement is secured by a first priority security interest in the Company’s accounts receivable, inventory and general intangibles, and a second priority security interest in the Company’s equipment and fixtures. All OTAs, PPAs, leases, supply agreements and/or similar agreements relating to solar PV and wind turbine systems or facilities, as well as all accounts receivable and assets of the Company related to the foregoing, are excluded from these liens, except to the extent the Company elects to finance any such assets with JP Morgan.

Borrowings under the Credit Agreement bear interest based on LIBOR plus an applicable margin (Applicable Margin), which ranges from 2.0% to 3.0% per annum based on the Company's debt service coverage ratio from time to time. The Company must pay a fee ranging between 0.25% and 0.50% per annum on the average daily unused amount of the Credit Facility (with the amount of such fee based on the Company's debt service coverage ratio from time to time) and a fee in the amount of the Applicable Margin on the daily average face amount of undrawn issued letters of credit. The fee on unused amounts is waived if the Company or its affiliates maintain funds on deposit with JP Morgan or its affiliates above a specified amount. The deposit threshold requirement was met as of March 31, 2014.

The amount of the benefit is based upon the ultimate deduction reflected in the applicable income tax return. Benefits of $1.0 million, $70,000 and $13,000 were recorded in fiscal 2012, fiscal 2013 and fiscal 2014, respectively, as a reduction in taxes payable and a credit to additional paid in capital based on the amount that was utilized in the current year.

As of March 31, 2014, the Company has federal net operating loss carryforwards of approximately $19.6 million, of which $3.5 million are associated with the exercise of NQSOs that have not yet been recognized by the Company in its financial statements. The Company also has state net operating loss carryforwards of approximately $15.8 million, of which $4.5 million are associated with the exercise of NQSOs. The Company also has federal tax credit carryforwards of approximately $1.5 million and state tax credits of $0.8 million. For the fiscal year ended March 31, 2014, the Company has recorded a valuation allowance of $7.9 million, equaling the net deferred tax asset due to the uncertainty of its realization value in the future. The Company considers future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance. In the event that the Company determines that the deferred tax assets are able to be realized, an adjustment to the deferred tax asset would increase income in the period such determination is made.

Generally, a change of more than 50% in the ownership of the Company's stock, by value, over a three year period constitutes an ownership change for federal income tax purposes as defined under Section 382 of the Internal Revenue Code. As a result, the Company's ability to use its net operating loss carryforwards, attributable to the period prior to such ownership change, to offset taxable income can be subject to limitations in a particular year, which could potentially result in increased future tax liability for the Company. The Company does not believe an ownership change affects the use of the full amount of the net operating loss carryforwards. There was no limitation that occurred for fiscal 2012, fiscal 2013, or fiscal 2014.

The Company records its tax provision based on the respective tax rules and regulations for the jurisdictions in which it operates. Where the Company believes that a tax position is supportable for income tax purposes, the item is included in their income tax returns. Where treatment of a position is uncertain, a liability is recorded based upon the expected most likely outcome taking into consideration the technical merits of the position based on specific tax regulations and facts of each matter. These liabilities may be affected by changing interpretations of laws, rulings by tax authorities, or the expiration of the statute of limitations.

As of December 31, 2011, an examination of the Company’s U.S. federal income tax returns for tax years 2009 to 2011 was complete. The resolution of this examination did not have a material effect on its business, financial condition, results of operations or liquidity.

State income tax returns are generally subject to examination for a period of 3 to 5 years after filing of the respective return. The state effect of any federal changes remains subject to examination by various states for a period of up to two years after formal notification to the states. The Company currently has no state income tax return positions in the process of examination, administrative appeals or litigation.

Uncertain tax positions

As of March 31, 2014, the balance of gross unrecognized tax benefits was approximately $0.2 million, all of which would reduce the Company’s effective tax rate if recognized. The Company does not expect this amounts to change in the next twelve months as none of the issues are currently under examination, the statutes of limitations do not expire within the period, and the Company is not aware of any pending litigation.

The Company has classified the amounts recorded for uncertain tax benefits in the balance sheet as other liabilities (non-current) to the extent that payment is not anticipated within one year. The Company recognizes penalties and interest related to uncertain tax liabilities in income tax expense. Penalties and interest are immaterial as of the date of adoption and are included in the unrecognized tax benefits. The Company had the following unrecognized tax benefit activity (in thousands):



	Fiscal Year Ended March 31,

The Company is subject to various claims and legal proceedings arising in the ordinary course of business. As of the date hereof, the Company is unable to currently assess whether the final resolution of any of such claims or legal proceedings may have a material adverse effect on the Company. In addition to ordinary-course litigation, the Company is a party to the proceedings described below.

In August 2012, the Company received a subpoena issued by the SEC requesting certain documents and information generally related to the financial reporting of its sales of solar photovoltaic systems, among other matters. The Company continues to cooperate with the SEC regarding this non-public, fact-finding inquiry. The SEC has informed the Company that this inquiry should not be construed as an indication that any violations of law have occurred or that the SEC has any negative opinion of any person, entity or security.

On March 27, 2014, the Company was named as a defendant in a civil lawsuit filed by Neal R. Verfuerth, the Company's former chief executive officer who was terminated for cause in November 2012, in the United States District Court for the Eastern District of Wisconsin (Green Bay Division). The plaintiff alleges, among other things, that the Company breached certain agreements entered into with the plaintiff, including the plaintiff’s employment agreement, and violated certain laws. The complaint seeks, among other relief, unspecified pecuniary and compensatory damages, fees and such other relief as the court may deem just and proper. The Company believes that the claims are meritless and that it has substantial legal and factual defenses to the claims and allegations contained in the complaint. The Company intends to defend against these claims vigorously.

Shareholders' Equity

Stockholders' Equity Note [Abstract]

SHAREHOLDERS' EQUITY

SHAREHOLDERS’ EQUITY

Share Repurchase Program and Treasury Stock

In October 2011, the Company’s Board of Directors approved a share repurchase program authorizing the Company to repurchase in aggregate up to a maximum of $1.0 million of the Company’s outstanding common stock. In November 2011, the Company’s Board of Directors approved an increase to the share repurchase program authorizing the Company to repurchase in aggregate up to a maximum of $2.5 million of the Company’s outstanding common stock. In April 2012, the Company's Board approved another increase to the share repurchase program authorizing the Company to repurchase in aggregate up to a maximum of $7.5 million of the Company's outstanding common stock. As of March 31, 2014, the Company had repurchased 3.0 million shares of common stock at a cost of $6.8 million under the program. The Company did not repurchase any shares in fiscal 2014 and does not intend to repurchase any additional common stock under this program in the near-term.

Shareholder Rights Plan

On January 7, 2009, the Company’s Board of Directors adopted a shareholder rights plan and declared a dividend distribution of one common share purchase right (Right) for each outstanding share of the Company’s common stock. The issuance date for the distribution of the Rights was February 15, 2009 to shareholders of record on February 1, 2009. Each Right entitles the registered holder to purchase from the Company one share of the Company’s common stock at a price of $30.00 per share, subject to adjustment (Purchase Price).

The Rights will not be exercisable (and will be transferable only with the Company’s common stock) until a “Distribution Date” occurs (or the Rights are earlier redeemed or expire). A Distribution Date generally will occur on the earlier of a public announcement that a person or group of affiliated or associated persons (Acquiring Person) has acquired beneficial ownership of 20% or more of the Company’s outstanding common stock (Shares Acquisition Date) or 10 business days after the commencement of, or the announcement of an intention to make, a tender offer or exchange offer that would result in any such person or group of persons acquiring such beneficial ownership.

If a person becomes an Acquiring Person, holders of Rights (except as otherwise provided in the shareholder rights plan) will have the right to receive that number of shares of the Company’s common stock having a market value of two times the then-current Purchase Price, and all Rights beneficially owned by an Acquiring Person, or by certain related parties or transferees, will be null and void. If, after a Shares Acquisition Date, the Company is acquired in a merger or other business combination transaction or 50% or more of its consolidated assets or earning power are sold, proper provision will be made so that each holder of a Right (except as otherwise provided in the shareholder rights plan) will thereafter have the right to receive that number of shares of the acquiring company’s common stock which at the time of such transaction will have a market value of two times the then-current Purchase Price.

Until a Right is exercised, the holder thereof, as such, will have no rights as a shareholder of the Company. At any time prior to a person becoming an Acquiring Person, the Board of Directors of the Company may redeem the Rights in whole, but not in part, at a price of $0.001 per Right. Unless they are extended or earlier redeemed or exchanged, the Rights will expire on January 7, 2019.

Employee Stock Purchase Plan

In August 2010, the Company’s board of directors approved a non-compensatory employee stock purchase plan, or ESPP. The ESPP authorizes 2,500,000 million shares to be issued from treasury or authorized shares to satisfy employee share purchases under the ESPP. All full-time employees of the Company are eligible to be granted a non-transferable purchase right each calendar quarter to purchase directly from the Company up to $20,000 of the Company’s common stock at a purchase price equal to 100% of the closing sale price of the Company’s common stock on the NYSE MKT exchange on the last trading day of each quarter. The ESPP allows for employee loans from the Company, except for Section 16 officers, limited to 20% of an individual’s annual income and no more than $250,000 outstanding at any one time. Interest on the loans is charged at the 10-year loan IRS rate and is payable at the end of each calendar year or upon loan maturity. The loans are secured by a pledge of any and all the Company’s shares purchased by the participant under the ESPP and the Company has full recourse against the employee, including offset against compensation payable. As of March 31, 2013, the Company had halted the loan program. The Company had the following shares issued from treasury during fiscal 2013 and fiscal 2014:



	As of March 31, 2013

Stock Options, Restricted Shares and Warrants

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

STOCK OPTIONS, RESTRICTED SHARES AND WARRANTS

The Company grants stock options and restricted stock under its 2003 Stock Option and 2004 Stock and Incentive Awards Plans (Plans). Under the terms of the Plans, the Company has reserved 13,500,000 shares for issuance to key employees, consultants and directors. The options generally vest and become exercisable ratably between one month and five years although longer and shorter vesting periods have been used in certain circumstances. Exercisability of the options granted to employees are generally contingent on the employees’ continued employment and non-vested options are subject to forfeiture if employment terminates for any reason. Options under the Plans have a maximum life of 10 years. In the past, the Company has granted both ISOs and NQSOs, although in July 2008, the Company adopted a policy of thereafter only granting NQSOs. Certain non-employee directors have elected to receive stock awards in lieu of cash compensation pursuant to elections made under the Company’s non-employee director compensation program. The Plans also provide to certain employees accelerated vesting in the event of certain changes of control of the Company as well as under other special circumstances.

In fiscal 2011, the Company converted all of its existing ISO awards to NQSO awards. No consideration was given to the employees for their voluntary conversion of ISO awards.

In June 2012, the Company's compensation committee approved the issuance of restricted shares under the Plans to key employees to provide an opportunity for such employees to earn long-term equity incentive awards. In May 2013, the Compensation Committee of the Board of Directors changed the Company's long-term equity incentive grant policy so that only restricted shares are issued to all employees under the Plans. The restricted shares are settled in Company stock when the restriction period ends. Compensation cost for restricted shares granted to employees is recognized ratably over the vesting term, which is between three to five years. Settlement of the shares is contingent on the employees’ continued employment and non-vested shares are subject to forfeiture if employment terminates for any reason. In fiscal 2013, an aggregate of 163,750 restricted shares were granted valued at a price per share between $1.80 and $2.00, which was the closing market price as of each grant date. In fiscal 2014, an aggregate of 526,663 restricted shares were granted valued at a price per share between $2.41 and $6.97, which was the closing market price as of each grant date.

In fiscal 2012, the Company granted 29,308 shares from the 2004 Stock and Incentive Awards Plan to certain non-employee directors who elected to receive stock awards in lieu of cash compensation. The shares were valued ranging from $2.43 to $4.19 per share, the closing market price as of the issuance dates. In fiscal 2013, the Company granted 30,422 shares from the 2004 Stock and Incentive Awards Plan to certain non-employee directors who elected to receive stock awards in lieu of cash compensation. The shares were valued ranging from $1.62 to $2.57 per share, the closing market price as of the issuance dates. In fiscal 2014, the Company granted 33,641 shares from the 2004 Stock and Incentive Awards Plan to certain non-employee directors who elected to receive stock awards in lieu of cash compensation. The shares were valued ranging from $2.41 to $5.73 per share, the closing market price as of the issuance dates. Additionally, during fiscal 2013, the Company issued 3,000 shares to a consultant as part of a consulting compensation agreement. The shares were valued at $2.03 per share, the closing market price as of the issuance date.

In fiscal 2014, the Company recorded $0.2 million of stock-based compensation related to the deferred consideration for employee Harris Shareholders resulting from the Harris acquisition. The following amounts of stock-based compensation were recorded (in thousands):

The Company’s revenue and long-lived assets outside the United States are insignificant.

Beginning in fiscal 2015, the Company intends to reorganize its business into the following business segments: U.S. markets, Orion engineered systems and Orion distribution services. The U.S. markets division will focus on selling lighting solutions into the wholesale markets. Its customers will include domestic energy service companies and electrical contractors. The Orion engineered systems division will focus on selling lighting products and construction and engineering services direct to end users. Additionally, Orion engineered systems will complete the construction management services related to existing contracted solar PV projects. Its customers will include national accounts, government, municipal and schools. The Orion distribution services division will focus on selling lighting products internationally and will begin to develop a network of broad line distributors. Historically, sales of all of the Company's lighting products and the related costs were combined through its energy management division. For this reason, the Company believes that it will be able to recast prior period revenue totals for the new segments, but does not believe that it will be able to practically recast the prior period operating income or loss for these new segments.

- Definition

The entire disclosure for reporting segments including data and tables. Reportable segments include those that meet any of the following quantitative thresholds a) it's reported revenue, including sales to external customers and intersegment sales or transfers is 10 percent or more of the combined revenue, internal and external, of all operating segments b) the absolute amount of its reported profit or loss is 10 percent or more of the greater, in absolute amount of 1) the combined reported profit of all operating segments that did not report a loss or 2) the combined reported loss of all operating segments that did report a loss c) its assets are 10 percent or more of the combined assets of all operating segments.

Tabular disclosure of components of a stock option or other award plan under which equity-based compensation is awarded to employees, typically comprised of the amount of unearned compensation (deferred compensation cost), compensation expense, and changes in the quantity and fair value of the shares (or other type of equity) granted, exercised, forfeited, and issued and outstanding pertaining to that plan. Disclosure may also include nature and general terms of such arrangements that existed during the period and potential effects of those arrangements on shareholders, effect of compensation cost arising from equity-based payment arrangements on the income statement, method of estimating the fair value of the goods or services received, or the fair value of the equity instruments granted, during the period, cash flow effects resulting from equity-based payment arrangements and, for registrants that accelerate vesting of out of the money share options, reasons for the decision to accelerate.

+ References+ Details

- Definition

Tabular disclosure of warrants or rights issued. Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.
