Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The condensed 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 have been made to prior years’ financial statements to conform to the current year presentation.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information and with the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Interim results are not necessarily indicative of results that may be expected for the year ending March 31, 2016 or other interim periods.

The condensed consolidated balance sheet at March 31, 2015 has been derived from the audited and adjusted consolidated financial statements at that date but does not include all of the information required by GAAP for complete financial statements.

The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2015 filed with the Securities and Exchange Commission on June 12, 2015.

Use of Estimates

The preparation of financial statements in conformity with 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.

Fair Value of Financial Instruments

The Company’s financial instruments consist of cash, 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:

Aging Analysis as of June 30, 2015 (in thousands):



	Not Past Due			1-90 days past due			Greater than 90 days past due			Total past due			Total sales-type leases
Lease balances included in consolidated accounts receivable—current	$	1,063		$	36		$	205		$	241		$	1,304
Lease balances included in consolidated accounts receivable—long-term	266			—			—			—			266

Allowance	(9		)	(2		)	(145		)	(147		)	(156		)
Total net sales-type leases	$	1,320		$	34		$	60		$	94		$	1,414

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 if 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 incurred no write-offs against its OTA sales-type lease receivable balances in fiscal 2015 or for the three months ended June 30, 2015.

Inventories

Inventories consist of raw materials and components, such as ballasts and drivers, light emitting diode (LED) chips, metal sheet and coil stock and molded parts; work in process inventories, such as frames and reflectors; and finished goods, including completed fixtures and accessories, such as lamps, sensors 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, 2015 and June 30, 2015, the Company had inventory obsolescence reserves of $1.6 million and $1.7 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 as of the dates set forth below (in thousands):



	March 31, 2015		June 30, 2015
Raw materials and components	$	8,474	$	8,673
Work in process	1,588		1,547
Finished goods	4,221		5,483
	$	14,283	$	15,703

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. Current deferred costs amounted to $0.1 million and $0.2 million as of March 31, 2015 and June 30, 2015, 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 included $1.7 million and $0.8 million of unbilled revenue as of March 31, 2015 and June 30, 2015, respectively.

Property and Equipment

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.

Property and equipment were comprised of the following as of the dates set forth below (in thousands):



	March 31, 2015			June 30, 2015
Land and land improvements	$	1,511		$	1,511
Buildings	14,441			14,441
Furniture, fixtures and office equipment	8,600			8,998
Leasehold improvements	148			148
Equipment leased to customers under Power Purchase Agreements	4,997			4,997
Plant equipment	11,084			11,094
Construction in progress	379			21
	41,160			41,210
Less: accumulated depreciation and amortization	(19,937		)	(20,672		)
Net property and equipment	$	21,223		$	20,538

Depreciation is provided over the estimated useful lives of the respective assets, using the straight-line method. Depreciable lives by asset category are as follows:



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

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. During the quarter ended June 30, 2015, the Company determined that a triggering event occurred due to the decline in the Company's share price when compared to the share price as of March 31, 2015. The Company performed a qualitative assessment of Goodwill and determined that no impairment had occurred.

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.

There was no change in the carrying value of goodwill during fiscal 2015 or for the three months ended June 30, 2015.

Goodwill is allocated to each operating segment during the three months ended June 30, 2015 as follows (in thousands):



	U.S. Markets		Orion Engineered Systems		Orion Distribution Services		Corporate and Other		Total
Goodwill at June 30, 2015	$	2,371	$	2,038	$	—	$	—	$	4,409

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



	March 31, 2015					June 30, 2015
	Gross Carrying Amount		Accumulated Amortization			Gross Carrying Amount		Accumulated Amortization
Patents	$	2,447	$	(906	)	$	2,447	$	(940	)
Licenses	58		(58		)	58		(58		)

Total	$	9,063	$	(2,728	)	$	9,063	$	(3,051	)

As of June 30, 2015, the weighted average useful life of intangible assets was 6.58 years. The estimated amortization expense for each of the next five years is shown below (in thousands):



Fiscal 2016	$	903
Fiscal 2017	883
Fiscal 2018	607
Fiscal 2019	431
Fiscal 2020	346
Fiscal 2021	271
Thereafter	613
Total	$	4,054

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 at 11%. As of June 30, 2015, the following amounts were due from the third party finance company in future periods (in thousands):



Fiscal 2016	$	279
Fiscal 2017	10
Total gross financed receivable	289
Less: amount above to be collected during the next 12 months	(279		)
Less: amount representing interest	(1		)
Net long-term receivable	$	9

Other Long-Term Assets

Other long-term assets include long-term security deposits, deferred costs for a long-term contract and deferred financing costs. Deferred financing costs as of March 31, 2015 and June 30, 2015 were $202 thousand and $175 thousand, respectively. Deferred financing costs related to debt issuances are amortized to interest expense over the life of the related debt issue (1 to 3 years) using the effective interest rate method.

Accrued Expenses and Other

Accrued expenses include warranty accruals, accrued wages and benefits, accrued vacation, accrued legal costs, accrued commissions, customer deposits, accrued project costs, sales tax payable and other various unpaid expenses. Accrued expenses include $1.3 million and $0.2 million of accrued project costs as of March 31, 2015 and June 30, 2015, respectively.

The Company generally offers a limited warranty of one year on its high intensity fluorescent (HIF) lighting products and a one to ten year limited warranty on its LED lighting products in addition to those standard warranties offered by major original equipment component manufacturers. The manufacturers’ warranties cover lamps, ballasts, drivers and LED chips, which are significant components in the Company’s lighting products. Included in other long-term liabilities is $0.3 million for warranty reserves related to solar operating systems. These warranties vary in length, with the longest coverage extended until 2030. Due to the limited warranty data available for solar operating systems of this nature, actual warranty claims may differ from the Company's estimate of these warranties.

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



	Three Months Ended June 30,
	2014			2015
Beginning of period	$	263		$	1,015
Provision to product cost of revenue	32			29
Charges	(42		)	18
End of period	$	253		$	1,062

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:


•	persuasive evidence of an arrangement exists;


•	delivery has occurred and title has passed to the customer;


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


•	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 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 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 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.

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. As of June 30, 2015, the Company had a valuation allowance of $21.1 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. For the three months ended June 30, 2014 and 2015, there were no realized tax benefits from the exercise of stock options.

Stock Based Compensation

The Company accounts for stock-based compensation in accordance with ASC 718, Compensation - Stock Compensation. Under the fair value recognition provisions of ASC718, stock-based compensation is measured at the grant date based on the fair value of the award and is recognized as expense ratably over the requisite service period, net of estimated forfeitures. As more fully described in Note I, the Company awards non-vested restricted stock to employees, executive officers and directors. The Company did not issue any stock options during fiscal 2015 or for the three months ended June 30, 2015.

Net Loss per Common Share

Basic net loss per common share is computed by dividing net 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 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 loss per common share, the Company uses the “treasury stock” method for outstanding options, warrants and restricted shares. The effect of net loss per common share is calculated based upon the following shares (in thousands except share amounts):



	Three Months Ended June 30,

Numerator:
Net loss (in thousands)	$	(4,359	)	$	(3,652	)

Concentration of Credit Risk and Other Risks and Uncertainties

The Company purchases components necessary for its lighting products, including ballasts, lamps and LED components from multiple suppliers. For the three months ended June 30, 2014 and 2015, no supplier accounted for more than 10% of total cost of revenue, respectively.

For the three months ended June 30, 2014 and 2015, no customer accounted for more than 10% of revenue, respectively.

As of March 31, 2015, and June 30, 2015, no customer accounted for more than 10% of accounts receivable.

Recent Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update No. 2014-09, "Revenue from Contracts with Customers" ("ASU 2014-09"). This ASU is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. In April 2015, the FASB proposed deferring the effective date of ASU 2014-09 to become effective for annual reporting periods beginning after December 15, 2017, and early adoption is permitted for annual reporting periods beginning after December 15, 2016. 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.

In June 2014, the FASB issued Accounting Standards Update No. 2014-12, "Compensation - Stock Compensation" ("ASU 2014-12"). ASU 2014-12 is intended to resolve diverse accounting treatment for share based awards in which the terms of the award provide that a performance target that affects vesting could be achieved after the requisite service period. The standard is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015 and may be applied prospectively or retrospectively. The Company does not expect adoption of this standard will have a significant impact on the Company's consolidated financial statements.

In August 2014, the FASB issued Accounting Standards Update No. 2014-15, "Presentation of Financial Statements - Going Concern" ("ASU 2014-15"). ASU 2014-15 requires an entity's management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern and if those conditions exist, the required disclosures. The standard is effective for annual periods ending after December 15, 2016, and interim periods therein. The Company does not expect adoption of this standard will have a significant impact on the Company's consolidated financial statements.

In April 2015, the FASB issued Accounting Standards Update No. 2015-03, "Interest - Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs" ("ASU 2015-03"). ASU 2015-03 requires that debt issuance costs be reported in the balance sheet as a direct deduction from the face amount of the related liability, consistent with the presentation of debt discounts. Prior to the amendments, debt issuance costs were presented as a deferred charge on the balance sheet. The standard is effective for annual periods ending after December 15, 2015 and interim periods within those fiscal years. The amendments must be applied retrospectively. The Company is currently evaluating the impact of ASU 2015-03.

Acquisition	3 Months Ended
Acquisition	Jun. 30, 2015
Business Combinations [Abstract]
ACQUISITION	ACQUISITION On July 1, 2013, the Company completed the acquisition 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. In December 2014, the Company amended the letter agreement to defer the January 2, 2015 payment of $0.8 million in cash until February 13, 2015, to settle all outstanding obligations related to the earn-out component of the Purchase Agreement. 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 was recorded as compensation expense through the end of calendar 2014. During the three months ended June 30, 2014, the Company expensed $49 thousand in compensation expense. On December 31, 2014, Harris was merged with and into the Company.

Revolving Credit Agreement

The Company has a revolving credit and security agreement (Credit Agreement) with Wells Fargo Bank, National Association. The Credit Agreement provides for a revolving credit facility (Credit Facility) that matures on February 6, 2018. Borrowings under the Credit Facility are initially limited to $15.0 million, subject to a borrowing base requirement based on eligible receivables and inventory. Such limit may increase to $20.0 million, subject to the borrowing base requirement, after July 31, 2016, if the Company satisfies certain conditions. The Credit Facility includes a $2.0 million sublimit for the issuance of letters of credit.

From and after any increase in the Credit Facility limit from $15.0 million to $20.0 million, the Credit Agreement will require the Company to maintain as of the end of each month a minimum ratio for the trailing twelve-month period of (i) earnings before interest, taxes, depreciation and amortization, subject to certain adjustments, to (ii) the sum of cash interest expense, certain principal payments on indebtedness and certain dividends, distributions and stock redemptions, equal to at least 1.10 to 1.00. The Credit Agreement also contains other customary covenants, including certain restrictions on the Company’s ability to incur additional indebtedness, consolidate or merge, enter into acquisitions, guarantee obligations of third parties, make loans or advances, declare or pay any dividend or distribution on the Company’s stock, redeem or repurchase shares of the Company’s stock, or pledge or dispose of assets.

Each subsidiary of the Company is a joint and several co-borrower or guarantor under the Credit Agreement, and the Credit Agreement is secured by a security interest in substantially all of the Company’s and each subsidiary’s personal property (excluding various assets relating to customer OTAs) and a mortgage on certain real property.

Borrowings under the Credit Agreement bear interest at the daily three-month LIBOR plus 3.0% per annum, with a minimum interest charge for each year or portion of a year during the term of the Credit Agreement of $130,000, regardless of usage. As of June 30, 2015, the interest rate was 3.28%. The Company must pay an unused line fee of 0.25% per annum of the daily average unused amount of the Credit Facility and a letter of credit fee at the rate of 3.0% per annum on the undrawn amount of letters of credit outstanding from time to time under the Credit Facility.

As of June 30, 2015, the Company had no outstanding letters of credit. Borrowings outstanding as of June 30, 2015, amounted to approximately $3.2 million and are included in non-current liabilities in the accompanying Consolidated Balance Sheet. The Company estimates that as of June 30, 2015, it was eligible to borrow an additional $1.8 million under the Credit Facility based upon current levels of eligible inventory and accounts receivable.

The Company was in compliance with its covenants in the Credit Agreement as of June 30, 2015.

New Equipment Lease Obligation

In June 2015, the Company entered into a lease agreement with De Lage Landen Financial Services, Inc in the principal amount of $0.4 million to fund certain equipment. The lease amount is secured by the related equipment. The lease bears interest at a rate of 5.94% and matures in June 2020 with a $1 buyout option.

Income Taxes

Jun. 30, 2015

Income Tax Disclosure [Abstract]

INCOME TAXES

The income tax provision for the three months ended June 30, 2015 was determined by applying an estimated annual effective tax rate of (0.1)% to loss before taxes. The estimated effective income tax rate was determined by applying statutory tax rates to pretax loss adjusted for certain permanent book to tax differences and tax credits. As of June 30, 2015, the Company had recorded a valuation allowance of $21.1 million, equaling the net deferred tax asset due to the uncertainty of its realization value in the future. ASC 740, Income Taxes, requires that a deferred tax asset be reduced by a valuation allowance if there is less than a 50% chance that it will be realized. The determination of the realization of deferred tax assets requires considerable judgment. ASC 740 prescribes the consideration of both positive and negative evidence in evaluating the need for a valuation allowance. Negative evidence for the Company includes a cumulative three year operating loss and limited visibility into future earnings. Positive evidence includes the Company's increasing proposal pipeline, recent new national account customer wins and the increase in revenue from new light emitting diode, or LED, products. The Company has determined that the negative evidence outweighs the current positive evidence and has concluded to record a valuation allowance.

Below is a reconciliation of the statutory federal income tax rate and the effective income tax rate:



	Three Months Ended June 30,
	2014		2015
Statutory federal tax rate	34.0	%	34.0	%
State taxes, net	3.1	%	3.5	%
Federal tax credit	1.6	%	2.0	%
State tax credit	0.7	%	0.8	%
Change in valuation reserve	(39.6	)%	(40.1	)%
Permanent items	—	%	(0.1	)%
Change in tax contingency reserve	—	%	(0.2	)%
Other, net	(0.1	)%	—	%
Effective income tax rate	(0.3	)%	(0.1	)%

The Company is eligible for tax benefits associated with the excess of the tax deduction available for exercises of non-qualified stock options, or NQSOs, over the amount recorded at grant. The amount of the benefit is based on the ultimate deduction reflected in the applicable income tax return. No benefits were recorded in fiscal 2015. No benefits were recorded for the three months ended June 30, 2015 as a reduction in taxes payable and a credit to additional paid in capital based on the amount that was utilized during the year.

As of June 30, 2015, the Company had federal net operating loss carryforwards of approximately $43.5 million, of which $3.7 million are associated with the exercise of NQSOs that have not yet been recognized by the Company. The Company also has state net operating loss carryforwards of approximately $32.2 million, of which $4.3 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 $0.5 million. As of June 30, 2015, the Company has recorded a valuation allowance of $21.1 million 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.

Uncertain Tax Positions

As of June 30, 2015, 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 amount to change during fiscal 2016 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. Due to the existence of net operating loss and credit carryforwards, all years since 2002 are open to examination by tax authorities.

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. For the three months ended June 30, 2014 and 2015, the Company had the following unrecognized tax benefit activity (in thousands):

COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Operating Leases and Purchase Commitments The Company leases vehicles, equipment and facility space under operating leases expiring at various dates through 2018. Rent expense under operating leases was $0.1 million for the three months ended June 30, 2014 and 2015, respectively. The Company enters into non-cancellable purchase commitments for certain inventory items in order to secure better pricing and ensure materials are on hand to meet anticipated order volume and customer expectations, as well as for capital expenditures. As of June 30, 2015, the Company had entered into $7.0 million of purchase commitments related to fiscal 2016, including $0.3 million for operating lease commitments and $6.7 million for inventory purchase commitments. Litigation 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. 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. On November 4, 2014, the court granted the Company's motion to dismiss six of the plaintiff's claims. On January 9, 2015, the plaintiff filed an amended complaint re-alleging claims that were dismissed by the court, including, among other things, a retaliation claim and certain claims with respect to prior management agreements and certain intellectual property rights. On January 22, 2015, the Company filed a motion to dismiss and a motion to strike certain of the claims made in the amended complaint. On May 18, 2015, the court dismissed the intellectual property claims re-alleged in the January 9, 2015 amended complaint. The Company believes that it has substantial legal and factual defenses to the claims and allegations remaining in the case and that the Company will prevail in this proceeding. The Company intends to continue to defend against the claims vigorously. Based upon the current status of the lawsuit, the Company is currently unable to estimate any potential adverse impact on the Company from the plaintiff's claims and the Company does not believe the lawsuit will have a material adverse impact on it future continuing results of operations. On May 29, 2014, the Equal Employment Opportunity Commission (EEOC) filed a claim against the Company alleging certain violations of the Americans with Disabilities Act (ADA) with regard to an employee. In addition, on August 20, 2014, the EEOC filed a claim against the Company alleging certain violations of the ADA with respect to the Company's wellness program. The Company does not believe these claims will have a material adverse impact on its future results of operations. State Tax Assessment The Company is currently negotiating a settlement with the Wisconsin Department of Revenue with respect to an assessment regarding the proper classification of the Company’s products for tax purposes under Wisconsin law. The issue under review is whether the installation of the Company’s lighting systems is considered a real property construction activity under Wisconsin law. The Company currently expects to resolve this matter with the Wisconsin Department of Revenue in fiscal 2016.

Shareholders' Equity

Stockholders' Equity Note [Abstract]

SHAREHOLDERS' EQUITY

SHAREHOLDERS’ EQUITY

Common Stock Transactions

On February 20, 2015, the Company completed an underwritten public offering of 5.46 million shares of its common stock, at an offering price to the public of $3.50 per share. Net proceeds of the offering approximated $17.5 million.

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 2.5 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 thousand 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 NASDAQ Capital Market 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 $0.25 million 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 issuing new loans under the program. The Company had the following shares issued from treasury as of March 31, 2015 and for the three months ended June 30, 2015:



	Shares Issued Under ESPP Plan	Closing Market Price	Shares Issued Under Loan Program	Dollar Value of Loans Issued		Repayment of Loans

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

STOCK OPTIONS, RESTRICTED SHARES AND WARRANTS

The Company grants stock options and restricted stock awards under its 2003 Stock Option and 2004 Stock and Incentive Awards Plans (Plans). Under the terms of the Plans, the Company has reserved 13.5 million 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. 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. 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 June 2012, the Compensation Committee of the Board of Directors 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. For the three months ended June 30, 2014, an aggregate of 222 thousand of restricted shares were granted valued at a price per share between $4.20 and $7.23, which was the closing market price as of each grant date.

For the three months ended June 30, 2015, an aggregate of 485 thousand of restricted shares were granted valued at a price per share between $2.21 and $2.62, which was the closing market price as of each grant date.

For the three months ended June 30, 2014, the Company issued 7 thousand shares under the Plans to certain non-employee directors who elected to receive stock awards in lieu of cash compensation. The shares were valued at $4.20 per share, the closing market price as of the issuance dates. For the three months ended June 30, 2015, the Company issued 7 thousand shares under the Plans to certain non-employee directors who elected to receive stock awards in lieu of cash compensation. The shares were valued at $2.62 per share, the closing market price as of the issuance dates.

The following amounts of stock-based compensation were recorded (in thousands):
