| SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | 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. 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, 2012 and 2013 were as follows (in thousands):
As of March 31, 2012 and 2013, 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 liabilities 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 The majority 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, 2012 (in thousands):
Age Analysis as of March 31, 2013 (in thousands):
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 write-off’s and credit losses against the OTA sales-type lease receivable balances in fiscal 2012 and fiscal 2013, respectively, was as follows:
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 12 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, 2012 and 2013, the Company had inventory obsolescence reserves of $1.5 million and $2.3 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):
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 $2.2 million and $2.1 million as of March 31, 2012 and March 31, 2013, 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 for contracts, unbilled revenue, prepaid taxes and miscellaneous receivables. 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 2011, 2012 or 2013. Property and equipment were comprised of the following (in thousands):
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 $2.7 million, $4.0 million and $4.3 million for the years ended March 31, 2011, 2012 and 2013, respectively. Depreciable lives by asset category are as follows:
No interest was capitalized for construction in progress during fiscal 2012 or fiscal 2013. Patents and Licenses Patents and licenses are amortized over their estimated useful life, ranging from 7 to 17 years, using the straight line method. The Company capitalized $157,000, $224,000 and $153,000 of costs associated with obtaining patents and licenses in fiscal 2011, 2012 and 2013, respectively. Amortization expense recorded to cost of revenue for fiscal 2011, 2012 and 2013 was $127,000, $136,000 and $133,000, respectively. The costs and accumulated amortization for patents and licenses were $2,262,000 and $573,000 as of March 31, 2012; and $2,416,000 and $707,000 as of March 31, 2013. The average remaining useful life of the patents and licenses as of March 31, 2013 was approximately 11.0 years. As of March 31, 2013, future amortization expense of the patents and licenses is estimated to be as follows (in thousands):
The Company’s management periodically reviews the carrying value of patents and licenses for impairment. Write-offs recorded in fiscal 2011, 2012 and 2013 were $0, $19,000 and $0, 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, 2013, the following amounts were due from the third party finance company in future periods (in thousands):
Long-Term Inventories The Company records long-term inventory for the non-current portion of its wireless controls finished goods 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, a note receivable, and deferred financing costs. Other long-term assets include $87,000 and $58,000 of deferred financing costs as of March 31, 2012 and March 31, 2013, respectively. Deferred financing costs related to debt issuances are amortized to interest expense over the life of the related debt issue (5 to 10 years). For the years ended March 31, 2011, 2012 and 2013, the amortization was $29,000, $52,000 and $42,000, respectively. Accrued Expenses and Other Accrued expenses include warranty accruals, accrued wages and benefits, accrued vacation, accrued bonuses, accrued legal costs, accrued commissions, accrued project costs, sales tax payable and other various unpaid expenses. Accrued expenses include $0 and $1.3 million of accrued reorganization costs as of March 31, 2012 and March 31, 2013. The Company generally offers a limited warranty of one year on its 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 products. Changes in the Company’s warranty accrual were as follows (in thousands):
Incentive Compensation The Company’s compensation committee approved an Executive Fiscal Year 2011 Annual Cash Incentive Program under its 2004 Stock and Incentive Awards Plan which became effective as of July 21, 2010. The plan provided for performance and discretionary bonus payments ranging from 7-19% of the fiscal 2011 base salaries of the Company’s named executive officers. The range of fiscal 2011 financial performance-based bonus guidelines under the approved plan began if the Company achieved a minimum of 1.2 times the fiscal 2010 revenue and a minimum of $4.0 million operating income. Based upon the results for the year ended March 31, 2011, the Company did not accrue any expense related to this plan. 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. 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:
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 established 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 evidence 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 evidence 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 evidence 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 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 $384,000, $117,000 and $111,000 for fiscal 2011, 2012 and 2013, 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, 2013, the Company recorded a valuation allowance of $4.1 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 were immaterial as of the date of adoption 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 $(132,000), $989,000 and $70,000 for the fiscal years 2011, 2012 and 2013, 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, 2011, 2012 and 2013, $(132,000), $989,000 and $70,000, 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 2011, 2012 and 2013 was determined using the assumptions in the following table:
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 employee stock options were exercised. 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 year ended March 31, 2013, 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):
The following table indicates the number of potentially dilutive securities as of the end of each period:
Concentration of Credit Risk and Other Risks and Uncertainties The Company’s cash is deposited with three 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 22% and 14% of total cost of revenue in fiscal 2011 and 2012, respectively. Currently, the Company has been able to obtain these components from multiple suppliers. For fiscal 2013, no supplier accounted for more than 10% of total cost of revenue. In fiscal 2011, 2012 and 2013, there were no customers who individually accounted for greater than 10% of revenue. As of March 31, 2012, one customer accounted for 11% and one customer accounted for 10% of accounts receivable. As of March 31, 2013, no customer accounted for more than 10% of accounts receivable. Recent Accounting Pronouncements In May 2011, the FASB issued ASU No. 2011-04 Fair Value Measurements (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in US GAAP and International Financial Reporting Standards (“IFRS”) (“ASU 2011-04”). ASU 2011-04 represents the converged guidance of the FASB and the IASB (the “Boards”) on fair value measurements. The collective efforts of the Boards and their staffs, reflected in ASU 2011-04, have resulted in common requirements for measuring fair value and for disclosing information about fair value measurements, including a consistent meaning of the term “fair value.” The Boards have concluded the common requirements will result in greater comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with GAAP and IFRSs. The amendments in this ASU are required to be applied prospectively, and are effective for interim and annual periods beginning after December 15, 2011. The adoption of ASU 2011-04 did not have a significant impact on the Company’s consolidated financial statements. In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (ASC Topic 220): Presentation of Comprehensive Income,” (“ASU 2011-05”) which amends current comprehensive income guidance. This accounting update eliminates the option to present the components of other comprehensive income as part of the statement of shareholders’ equity. Instead, the Company must report comprehensive income in either a single continuous statement of comprehensive income which contains two sections, net income and other comprehensive income, or in two separate but consecutive statements. ASU 2011-05 will be effective for public companies during the interim and annual periods beginning after December 15, 2011 with early adoption permitted. However, in December 2011, the FASB issued ASU No. 2011-12, “Deferral of the Effective Date for Amendments to the Presentation of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05” (“ASU 2011-12”), which deferred the guidance on whether to require entities to present reclassification adjustments out of accumulated other comprehensive income by component in both the statement where net income is presented and the statement where other comprehensive income is presented for both interim and annual financial statements. ASU 2011-12 reinstated the requirements for the presentation of reclassifications that were in place prior to the issuance of ASU 2011-05 and did not change the effective date for ASU 2011-05. For public entities, the amendments in ASU 2011-05 and ASU2011-12 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, and should be applied retrospectively. The adoption of ASU 2011-05 and ASU 2011-12 did not have a significant impact on the Company’s consolidated statements as it only requires a change in the format of the current presentation. In December 2011, the FASB issued ASU No. 2011-11, “Balance Sheet: Disclosures about Offsetting Assets and Liabilities.” ASU 2011-11 requires entities to disclose information about offsetting and related arrangements of financial instruments and derivative instruments and will be applied retrospectively for all comparative periods presented. ASU 2011-11 is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The adoption of ASU 2011-11 did not have a significant impact on the Company's consolidated financial statements. In February 2013, The FASB issued Accounting Standards Update No. 2013-02, "Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income", to improve the transparency of reporting reclassifications out of accumulated other comprehensive income. ASU 2013-02 requires an organization to present (either on the face of the statement where net income is presented or in the notes) the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income–but only if the item reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. The amendments are effective for reporting periods beginning after December 15, 2012. The adoption of ASU 2013-12 did not have a significant impact on the Company's consolidated financial statements. |

| LONG-TERM DEBT | LONG-TERM DEBT Long-term debt as of March 31, 2012 and 2013 consisted of the following (in thousands):
Revolving Credit Agreement The Company has a 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 June 30, 2013. The Company is currently working on a renewal of the Credit Facility. 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, 2013, the Company had outstanding letters of credit totaling $1.7 million, primarily for securing collateral requirements under equipment operating leases. There were no loans outstanding under the Credit Agreement as of March 31, 2012 or March 31, 2013. In February 2013, the Company completed an amendment to the Credit Agreement making certain changes to the financial covenants, which are described below. The Credit Agreement, as amended, 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 and (iii) EBITDA of at least $1.0 million during each 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 in compliance with all covenants in the Credit Agreement, as amended, as of March 31, 2013. 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 (the 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 not met as of March 31, 2013. Customer Equipment Finance Notes Payable In September 2010, the Company entered into a note agreement with a financial institution that provided the Company with $2.4 million to fund completed customer contracts under the Company’s OTA finance program. In February 2011, the Company sold a portion of the OTA contracts collateralizing the note to a third party equipment finance company. Accordingly, the Company repaid $1.3 million of the outstanding note balance and recorded a prepayment penalty of $33,000. This note is included in the table above as customer equipment finance notes payable. The note is collateralized by the OTA-related equipment and the expected future monthly payments under the supporting 14 individual OTA customer contracts. The note bears interest at 7% and matures in September 2015. The note agreement includes certain prepayment penalties and a covenant that the Company maintain at least $5 million in cash liquidity. The Company was in compliance with all covenants in the note agreement as of March 31, 2013. In March 2011, the Company entered into a note agreement with a financial institution that provided the Company with $0.9 million to fund completed customer contracts under the Company’s OTA finance program. This note is included in the table above as customer equipment finance notes payable. The note is collateralized by the OTA-related equipment and the expected future monthly payments under the supporting three individual OTA customer contracts. The note bears interest at 7% and requires monthly payments of $20,900 through April 2015. The note agreement includes certain prepayment penalties and a covenant that the Company maintain at least $5 million in cash liquidity. The Company was in compliance with all covenants in the note agreement as of March 31, 2013. In June 2011, the Company entered into a note agreement with a financial institution that provided the Company with $2.8 million to fund completed customer contracts under the Company’s OTA finance program. The note is collateralized by the OTA-related equipment and the expected future monthly payments under the supporting 41 individual OTA contracts. The note bears interest at 7.85% and matures in April 2016. The note agreement includes a debt service covenant with respect to the supporting OTA contracts that the aggregate amount of all remaining scheduled payments due with respect to the individual OTA contracts be not less than 1.25 to 1.0 of the remaining principal and interest payments due under the loan. As of March 31, 2013 the Company was in compliance with the debt service covenant. In September 2011, the Company entered into a credit agreement with JP Morgan that provided the Company with up to $5.0 million that was immediately available to fund completed customer contracts under its OTA finance program. The Company had one year from the date of the commitment to borrow under the credit agreement, which expired on September 30, 2012 for new borrowings. As of March 31, 2013, the Company had $2.2 million outstanding under the credit agreement. There were no new borrowings during fiscal 2013. The loan amount is collateralized by the OTA-related equipment and the expected future monthly payments under the supporting 38 individual OTA customer contracts. The current loan amount under the credit agreement bears interest at LIBOR plus 4% and matures in December 2016. In February 2013, the Company completed an amendment to the credit agreement making certain changes to the financial covenants requiring the Company to maintain (i) average daily unencumbered liquidity of at least $20.0 million during each period of three consecutive business days and (ii) EBITDA of at least $1.0 million during each fiscal quarter. The Company was in compliance with all covenants, as amended, in the credit agreement as of March 31, 2013. Term Note The Company’s term note requires principal and interest payments of $25,000 per month payable through February 2014 at an interest rate of 6.9%. Amounts outstanding under the note are secured by a first security interest and first mortgage in certain long-term assets and a secondary interest in inventory and accounts receivable and a secondary general business security agreement on all assets. In addition, the agreement precludes the payment of dividends on the Company's common stock. Amounts outstanding under the note are 75% guaranteed by the United States Department of Agriculture Rural Development Association. First Mortgage Note Payable The Company’s first mortgage note payable has an interest rate of prime plus 2.25% (effective rate of 5.50% at March 31, 2013), and requires monthly payments of principal and interest of $10,000 through December 2014. The mortgage is secured by a first mortgage on the Company’s manufacturing facility. The mortgage includes certain prepayment penalties and various restrictive covenants, with which the Company was in compliance as of March 31, 2013. Debenture Payable The Company’s debenture payable was issued by Certified Development Company at an effective interest rate of 4.94%. The balance is payable in monthly principal and interest payments of $8,000 through December 2024 and is guaranteed by United States Small Business Administration 504 program. The amount due was collateralized by a second mortgage on the manufacturing facility.

A reconciliation of the statutory federal income tax rate and effective income tax rate is as follows:
The net deferred tax assets and liabilities reported in the accompanying consolidated financial statements include the following components (in thousands):
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 upon the ultimate deduction reflected in the applicable income tax return. Benefits of $(0.1) million, $1.0 million and $70,000 were recorded in fiscal 2011, fiscal 2012 and fiscal 2013, 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. During the fourth quarter of fiscal 2011, the Company converted almost all of its existing incentive stock options, or ISOs, to NQSOs. This conversion was applied retrospectively, allowing the Company to benefit $0.6 million of income tax expense related to non-deductible ISO stock compensation expense that was previously deferred for income tax purposes. The conversion reduced the effective tax rate for fiscal 2011 to a benefit rate of 137.8% from a pre-conversion income tax benefit rate of 69.8%. As of March 31, 2013, the Company has federal net operating loss carryforwards of approximately $9.9 million, of which $3.0 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 $10.3 million, of which $4.1 million are associated with the exercise of NQSOs. The Company also has federal tax credit carryforwards of approximately $1.4 million and state tax credits of $0.7 million. For the fiscal year ended March 31, 2013, the Company has recorded a valuation allowance of $7.1 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 or fiscal 2013. 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, 2013, 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):

| COMMITMENTS AND CONTINGENCIES | COMMITMENTS AND CONTINGENCIES Operating Leases The Company leases vehicles and equipment under operating leases expiring at various dates through 2021. Rent expense under operating leases was $1,810,000, $2,111,000 and $1,613,000 for fiscal 2011, 2012 and 2013, respectively. Total annual commitments under non-cancelable operating leases with terms in excess of one year at March 31, 2013 are as follows (in thousands):
Purchase Commitments The Company enters into non-cancellable purchase commitments for certain inventory items in order to secure better pricing and ensure materials on hand and capital expenditures. As of March 31, 2013, the Company had entered into $10.1 million of purchase commitments related to fiscal 2014 for inventory purchases. Retirement Savings Plan The Company sponsors a tax deferred retirement savings plan that permits eligible employees to contribute varying percentages of their compensation up to the limit allowed by the Internal Revenue Service. This plan also provides for discretionary Company contributions. In fiscal 2011, 2012 and 2013, the Company made matching contributions of approximately $7,000, $15,000 and $8,000, respectively. Litigation The Company is subject to various claims and legal proceedings. The Company is unable to currently assess whether the final resolution of any of such claims or legal proceedings may have a material adverse affect on the Company. In August 2012, the Company received a subpoena issued by the staff of the Securities and Exchange Commission, or SEC, requesting certain documents and information generally related to the Company's 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. |

| 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, 2013, the Company had repurchased 3,002,200 shares of common stock at a cost of $6,742,000 under the program. The Company does not intend to repurchase 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 (a “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 (the “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 (an “Acquiring Person”) has acquired beneficial ownership of 20% or more of the Company’s outstanding common stock (a “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 2012 and fiscal 2013:
Loans issued to employees are reflected on the Company’s balance sheet as a contra-equity account. |

| STOCK OPTIONS, RESTRICTED SHARES AND WARRANTS | STOCK OPTIONS, RESTRICTED SHARES AND WARRANTS The Company grants stock options under its 2003 Stock Option and 2004 Stock and Incentive Awards Plans (the "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 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. The Company granted accelerated vesting stock options in May 2011 under its 2004 Stock and Incentive Awards Plan to provide an opportunity for its employees to earn long-term equity incentive awards based on the Company’s financial performance for fiscal 2012. An aggregate of 459,041 stock options were granted on the third business day following the Company’s public release of its fiscal 2011 results at an exercise price per share of $4.19, which was the closing sale price of the Company’s Common Stock on that date. The stock options only vested, however, if the optionee remained employed and the Company was successful in achieving at least 100% of the target levels for each of the Company’s three financial metric targets for fiscal 2012, and if the Company’s stock price equaled or exceeded $5.00 per share for at least 20 trading days during any 90-day period during the options’ ten-year term. As of March 31, 2012, the Company did not achieve 100% of all three of the financial metric targets and the options were subsequently cancelled. 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. 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. An aggregate of 138,750 of restricted shares were granted on June 18, 2012 valued at a price per share of $2.00, which was the closing market price as of the grant date. Additionally, 25,000 restricted shares were granted on September 27, 2012 valued at a price per share of $1.80, which was the closing market price as of the grant date. In fiscal 2011, the Company granted 15,475 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 $2.86 to $3.93 per share, the closing market price as of the issuance dates. 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. 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. The following amounts of stock-based compensation were recorded (in thousands):
The number of shares available for grant under the plans were as follows:
The following table summarizes information with respect to outstanding stock options:
The following table summarizes the range of exercise prices on outstanding stock options at March 31, 2013:

| SUBSEQUENT EVENTS | SUBSEQUENT EVENTS On May 22, 2013, the Company executed a Stock and Unit Purchase Agreement (the "Purchase Agreement") with Harris Manufacturing, Inc. and Harris LED, LLC.

| Accounting Policies [Abstract] | |||||||||||||||||
| Principles of Consolidation | 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. |
||||||||||||||||
| Use of Estimates | 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 | 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 | Fair Value of Financial Instruments The Company’s financial instruments consist of cash, short-term investments, accounts receivable, accounts payable, accrued liabilities 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 | Accounts Receivable The majority 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 | 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. 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. |
||||||||||||||||
| Inventories | 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 12 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, 2012 and 2013, the Company had inventory obsolescence reserves of $1.5 million and $2.3 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. |
||||||||||||||||
| Deferred Contract Costs | 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. |
||||||||||||||||
| Prepaid Expenses and Other Current Assets | 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 for contracts, unbilled revenue, prepaid taxes and miscellaneous receivables. |
||||||||||||||||
| Property and Equipment | 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. |
||||||||||||||||
| Patents and Licenses | Patents and Licenses Patents and licenses are amortized over their estimated useful life, ranging from 7 to 17 years, using the straight line method. |
||||||||||||||||
| Long Term Receivables | 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%. |
||||||||||||||||
| Long Term Inventories | Long-Term Inventories The Company records long-term inventory for the non-current portion of its wireless controls finished goods inventory. The inventories are stated at the lower of cost or market value with cost determined using the FIFO method. |
||||||||||||||||
| Standard Product Warranty | The Company generally offers a limited warranty of one year on its 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 products. |
||||||||||||||||
| Revenue Recognition | 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:
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 established 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 evidence 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 evidence 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 evidence 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 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 | 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. |
||||||||||||||||
| Research and Development | Research and Development The Company expenses research and development costs as incurred. |
||||||||||||||||
| Income Taxes | 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, 2013, the Company recorded a valuation allowance of $4.1 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 were immaterial as of the date of adoption 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. |
||||||||||||||||
| Stock Option Plans | 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, 2011, 2012 and 2013, $(132,000), $989,000 and $70,000, 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. |
||||||||||||||||
| Net Income (Loss) per Common Share | 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 employee stock options were exercised. 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 year ended March 31, 2013, because the effects of potentially dilutive securities are anti-dilutive. |
||||||||||||||||
| Concentration of Credit Risk and Other Risks and Uncertainties | Concentration of Credit Risk and Other Risks and Uncertainties The Company’s cash is deposited with three 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. |

| Recent Accounting Pronouncements | Recent Accounting Pronouncements In May 2011, the FASB issued ASU No. 2011-04 Fair Value Measurements (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in US GAAP and International Financial Reporting Standards (“IFRS”) (“ASU 2011-04”). ASU 2011-04 represents the converged guidance of the FASB and the IASB (the “Boards”) on fair value measurements. The collective efforts of the Boards and their staffs, reflected in ASU 2011-04, have resulted in common requirements for measuring fair value and for disclosing information about fair value measurements, including a consistent meaning of the term “fair value.” The Boards have concluded the common requirements will result in greater comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with GAAP and IFRSs. The amendments in this ASU are required to be applied prospectively, and are effective for interim and annual periods beginning after December 15, 2011. The adoption of ASU 2011-04 did not have a significant impact on the Company’s consolidated financial statements. In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (ASC Topic 220): Presentation of Comprehensive Income,” (“ASU 2011-05”) which amends current comprehensive income guidance. This accounting update eliminates the option to present the components of other comprehensive income as part of the statement of shareholders’ equity. Instead, the Company must report comprehensive income in either a single continuous statement of comprehensive income which contains two sections, net income and other comprehensive income, or in two separate but consecutive statements. ASU 2011-05 will be effective for public companies during the interim and annual periods beginning after December 15, 2011 with early adoption permitted. However, in December 2011, the FASB issued ASU No. 2011-12, “Deferral of the Effective Date for Amendments to the Presentation of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05” (“ASU 2011-12”), which deferred the guidance on whether to require entities to present reclassification adjustments out of accumulated other comprehensive income by component in both the statement where net income is presented and the statement where other comprehensive income is presented for both interim and annual financial statements. ASU 2011-12 reinstated the requirements for the presentation of reclassifications that were in place prior to the issuance of ASU 2011-05 and did not change the effective date for ASU 2011-05. For public entities, the amendments in ASU 2011-05 and ASU2011-12 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, and should be applied retrospectively. The adoption of ASU 2011-05 and ASU 2011-12 did not have a significant impact on the Company’s consolidated statements as it only requires a change in the format of the current presentation. In December 2011, the FASB issued ASU No. 2011-11, “Balance Sheet: Disclosures about Offsetting Assets and Liabilities.” ASU 2011-11 requires entities to disclose information about offsetting and related arrangements of financial instruments and derivative instruments and will be applied retrospectively for all comparative periods presented. ASU 2011-11 is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The adoption of ASU 2011-11 did not have a significant impact on the Company's consolidated financial statements. In February 2013, The FASB issued Accounting Standards Update No. 2013-02, "Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income", to improve the transparency of reporting reclassifications out of accumulated other comprehensive income. ASU 2013-02 requires an organization to present (either on the face of the statement where net income is presented or in the notes) the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income–but only if the item reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. The amendments are effective for reporting periods beginning after December 15, 2012. The adoption of ASU 2013-12 did not have a significant impact on the Company's consolidated financial statements. |

Tabular disclosure of warrants or rights issued.

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.
