Summary of Significant Accounting Policies	Mar. 31, 2017
Accounting Policies [Abstract]
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. Reclassifications Where appropriate, certain reclassifications have been made to prior years’ financial statements to conform to the current year presentation. 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 allowance for doubtful accounts, accruals for warranty and loss contingencies, income taxes and certain equity transactions. Accordingly, actual results could differ from those estimates. Cash and Cash Equivalents Orion considers all highly liquid, short-term investments with original maturities of three months or less to be cash equivalents. Fair Value of Financial Instruments Orion’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and other, revolving credit facility and long-term debt. The carrying amounts of Orion’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 debt and revolving credit facility, because of the interest rates currently available to Orion 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. Allowance for Doubtful Accounts Orion performs ongoing evaluations of its customers and continuously monitors collections and payments and estimate an allowance for doubtful accounts based upon the aging of the underlying receivables, historical experience with write-offs and specific customer collection issues that have been identified. See Note 3 - Accounts Receivable for further discussion of the allowance for doubtful accounts Long-Term Receivables Orion 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. Orion uses the implied cost of capital from each individual contract as the discount rate. Deferred Contract Costs Deferred contract costs consist primarily of the costs of products delivered, and services performed, that are subject to additional performance obligations or customer acceptance. These deferred contract costs are expensed at the time the related revenue is recognized. Deferred costs amounted to $935,000 as of March 31, 2017 and $37,000 as of March 31, 2016. Incentive Compensation Orion’s compensation committee approved an Executive Fiscal Year 2017 Annual Cash Incentive Program under its 2004 Stock and Incentive Plan. The plan provided for performance cash bonus payments ranging from 35-100% of the fiscal 2017 base salaries of Orion’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 2017 of at least (i) $500,000 of profit before taxes and (ii) revenue growth of 10% more than fiscal year 2016. Based upon the results for the year ended March 31, 2017, Orion did not accrue any expense related to this plan. Orion’s compensation committee approved an Executive Fiscal Year 2016 Annual Cash Incentive Program under its 2004 Stock and Incentive Awards Plan. The plan provided for performance cash bonus payments ranging from 35-100% of the fiscal 2016 base salaries of Orion’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 2016 of at least (i) $110,000 of profit before taxes and (ii) revenue growth of 10% more than fiscal year 2015. Based upon the results for the year ended March 31, 2016, Orion did not accrue any expense related to this plan. Orion’s compensation committee approved an Executive Fiscal Year 2015 Annual Cash Incentive Program under its 2004 Stock and Incentive Awards Plan. The plan provided for performance cash bonus payments ranging from 35-100% of the fiscal 2015 base salaries of Orion’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 2015 of at least (i) $2,300,000 of profit before taxes and (ii) revenue of at least $90,400,000. Based upon the results for the year ended March 31, 2015, Orion did not accrue any expense related to this plan. Revenue Recognition Revenue is recognized on the sales of Orion's lighting and related energy-efficiency systems and products when the following four criteria are met: 1.persuasive evidence of an arrangement exists; 2.delivery has occurred and title has passed to the customer; 3.the sales price is fixed and determinable and no further obligation exists; and 4.collectability is reasonably assured. These four criteria are met for Orion’s product-only revenue upon delivery of the product and title passing to the customer. At that time, Orion 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 Orion’s lighting and energy management technologies under multiple element arrangements, consisting of a combination of product sales and services, Orion 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, Orion 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 Orion determines estimated selling price is provided below). The nature of Orion’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, Orion establishes the selling price for its energy management system products using management's best estimate of the selling price, as VSOE and TPE do not exist. Product revenue is recognized when title and risk of loss for the products transfers. For product revenue, management's best estimate of selling price is determined using a cost plus gross profit margin method. In addition, Orion records in service revenue the selling price for its installation and recycling services using management’s best estimate of selling price, as VSOE and TPE do 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. Orion’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 and TPE do 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 Orion's installation and recycling services, under a multiple-element arrangement, management’s best estimate of selling price is determined using a cost plus gross profit margin method with consideraion given to other relevant economic conditions and trends, customer demand, pricing practices, and margin objectives. The determination of an estimated selling price is made through consultation with and approval by management, taking into account the preceding factors. Orion offers a financing program, called an Orion Throughput Agreement, or OTA, for a customer’s lease of Orion’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 Orion’s net investment in the lease, which typically is the net present value of the future cash flows. Orion has limited Power Purchase Agreement (“PPA”) contracts still outstanding. Those PPA’s outstanding are supply side agreements for the generation of electricity for which we recognize revenue on a monthly basis over the life of the PPA contract, typically in excess of 10 years. Prior to fiscal 2015, Orion sold solar PV systems which were recognized to revenue using the percentage-of-completion method by measuring project progress by the percentage of costs incurred to date of the total estimated costs for each contract as materials are installed. Revenue from sales of Orion's solar PV systems is generally recognized over a period of three to 15 months. There were no sales of solar PV systems in fiscal 2017, fiscal 2016 or fiscal 2015. Deferred revenue relates to advance customer billings, investment tax grants received related to PPAs and long term maintenance contracts on OTAs and is classified as a liability on the condensed 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 Orion 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 $94,000, $4,000 and $149,000 for fiscal 2017, 2016 and 2015, respectively, were charged to operations as incurred. Research and Development Orion expenses research and development costs as incurred. Amounts are included in the Statement of Operations and Comprehensive Income on the line item Research and development. Income Taxes Orion 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 carry-forwards. 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, 2017, Orion recorded a full valuation allowance of $4,627,000 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. Orion 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. Orion recognizes penalties and interest related to uncertain tax liabilities in income tax expense. Penalties and interest are immaterial and are included in the unrecognized tax benefits. Deferred tax benefits have not been recognized for income tax effects resulting from the exercise of non-qualified stock options. These benefits will be recognized in the period in which the benefits are realized as a reduction in taxes payable and an increase in additional paid-in capital. Realized tax benefits (expense) from the exercise of stock options were $0, for the fiscal years 2017, 2016 and 2015. Stock Based Compensation Orion’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. Orion realized no such tax benefits during the years ended March 31, 2017, 2016 and 2015. Historically, Orion uses the Black-Scholes option-pricing model for issued stock options. Orion calculated 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 was based upon the vesting term of Orion’s options and expected exercise behavior. Orion accounts for stock-based compensation in accordance with ASC 718, Compensation - Stock Compensation. Under the fair value recognition provisions of ASC 718, 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 9, Orion currently awards non-vested restricted stock to employees, executive officers and directors. Orion did not issue any stock options during fiscal 2017, fiscal 2016 or fiscal 2015. Orion has not paid dividends in the past and does not plan to pay any dividends in the foreseeable future. Orion estimates its forfeiture rate of unvested stock awards based on historical experience. Concentration of Credit Risk and Other Risks and Uncertainties Orion’s cash is deposited with two financial institutions. At times, deposits in these institutions exceed the amount of insurance provided on such deposits. Orion has not experienced any losses in such accounts and believes that it is not exposed to any significant financial institution viability risk on these balances. Orion purchases components necessary for its lighting products, including ballasts, lamps and LED components, from multiple suppliers. For fiscal 2017, 2016 and 2015, no supplier accounted for more than 10% of total cost of revenue. In fiscal 2017 and fiscal 2016, no customer accounted for 10% of revenue. In fiscal 2015, one customer accounted for 12% of revenue. As of March 31, 2017, one customer accounted for 11.6% of accounts receivable and as of March 31, 2016, one customer accounted for 10.3% of accounts receivable. Recent Accounting Pronouncements Issued: Not Yet Adopted In August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-15, "Classification of Certain Cash Receipts and Cash Payments," which provides clarification and additional guidance as to the presentation and classification of certain cash receipts and cash payments in the statement of cash flows. The ASU provides guidance, as to the classification of a number of transactions including: contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, and distributions received from equity method investees. The new standard will be effective for Orion in the first quarter of fiscal 2019 and will be applied through retrospective adjustment to all periods presented. Orion does not expect the adoption of this guidance to have a material impact on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Subtopic 842)." This ASU requires that lessees recognize right-of-use assets and liabilities on the balance sheet for the rights and obligations created by long-term leases and disclose additional quantitative and qualitative information about leasing arrangements. Under this ASU, leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition. Similarly, lessors will be required to classify leases as sales-type, finance or operating leases, with classification affecting the pattern of income recognition. Classification for both lessees and lessors will be based on an assessment of whether risks and rewards as well as substantive control have been transferred through the lease contract. This ASU also provides guidance on the presentation of the effects of leases in the income statement and statement of cash flows. This guidance will be effective for Orion on April 1, 2019. Early adoption of the standard is permitted and a modified retrospective transition approach is required for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company has not yet completed its review of the full provisions of this standard against its outstanding lease arrangements and is in the process of quantifying the lease liability and related right of use asset which will be recorded to its consolidated balance sheets upon adoption of the standard. In addition, management continues to assess the impact of adoption of this standard on its consolidated statements of operations, cash flows, and the related footnote disclosures. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers." This ASU is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of 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 addition, the ASU requires enhanced and expanded financial statement disclosures. Since the issuance of this ASU, the FASB has issued further ASU’s to provide additional guidance and clarification as to the application of ASU 2014-09 and delaying its original effective date. The ASU allows companies to elect either a full retrospective or modified retrospective approach to adoption. Orion will adopt ASU 2014-09 and the related updates with their effective date on April 1, 2018. Orion has begun the process of implementing this standard, including performing a review of its revenue streams to identify any differences in the timing, measurement, or presentation of revenue recognition. The Company is in the process of reviewing the provisions of these standards against its customer contracts, including evaluating and identifying distinct performance obligations. The Company continues to evaluate its customer contracts to determine the impact on the timing and presentation of revenue. In addition, the Company is evaluating any necessary changes to its revenue related processes and controls as a result of the new standard, including the related footnote disclosures. Under ASU 2014-09 incremental contract costs, including sales commissions, may be required to be capitalized and expensed over the period these costs are recovered. Although Orion incurs commission costs, its contracts are typically completed within one year. As such, the Company will elect to apply the practical expedient for contract costs recovered within one year and will continue to recognize commissions as cost of sales immediately rather than capitalizing and expensing these costs over the contract period. Orion currently plans to elect the modified retrospective adoption method but continues to evaluate both of the available transition methods. In November 2015, the FASB issued ASU 2015-17, “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes,” to simplify the presentation of deferred taxes. The amendments in this update require that deferred tax assets and liabilities be classified as non-current on the balance sheet. This ASU is effective for Orion's annual reporting period, and interim periods therein, as of April 1, 2017. The adoption of this standard will have no impact on Orion’s consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory,” which changes the measurement principle for inventory from the lower of cost or market to the lower of cost or net realizable value for entities that measure inventory using first-in, first-out ("FIFO") or average cost. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This ASU is effective for Orion on April 1, 2017. The Company believes the adoption of this standard will not have a material impact on Orion’s consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting," which changes how companies account for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as the classification of related matters in the statement of cash flows. The ASU is effective for Orion as of April 1, 2017. The adoption of this standard is not expected to have a material impact on Orion’s consolidated financial statements. Recently Adopted Standards As of April 1, 2016, Orion adopted the provisions of ASU 2015-03 “Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs” and the related ASU 2015-15 “Interest-Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line of Credit Arrangements- Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting (SEC Update).” This guidance requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a reduction of the carrying amount of that debt liability, consistent with debt discounts, with the exception of debt issuance costs associated with line of credit agreements which may remain classified as an asset and amortized ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. As Orion’s only deferred debt issuance costs relate to its revolving line of credit, upon adoption of these standards a reclassification of the deferred financing costs was not required and there was no impact on Orion’s condensed consolidated financial statements. In August 2014, the FASB issued ASU 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 prescribes the necessary disclosures. Orion incorporated the provisions of this standard in performing its going concern analysis as of March 31, 2017. The adoption of this standard did not have an impact on Orion’s consolidated financial statements or footnote disclosures.

Receivables [Abstract]

ACCOUNTS RECEIVABLE

Orion’s accounts receivable are due from companies in the commercial, governmental, 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 Orion expects to collect from outstanding balances. Orion 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 Orion has used reasonable collection efforts are written off through a charge to the allowance for doubtful accounts and a credit to accounts receivable. Orion's accounts receivable and allowance for doubtful accounts balances were as follows (dollars in thousands):



	2017			2016
Accounts receivable, gross	$	9,315		$	11,394

Allowance for Credit Losses on Financing Receivables

Orion’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 Orion'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. Orion 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. Orion’s provision for write-offs and credit losses against the OTA sales-type lease receivable balances in fiscal 2017, fiscal 2016 and fiscal 2015, respectively, was as follows (dollars in thousands):

Inventory Disclosure [Abstract]

INVENTORIES

Inventories consist of raw materials and components, such as drivers, 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 accessories. All inventories are stated at the lower of cost or market value with cost determined using the first-in, first-out (FIFO) method. Orion 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. Orion 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, 2017 and 2016, Orion's inventory balances were as follows (dollars in thousands):



	Cost		Obsolescence Reserve			Net
As of March 31, 2017
Raw materials and components	$	8,104	$	(1,807	)	$	6,297
Work in process	1,918		(329		)	1,589
Finished goods	7,044		(1,337		)	5,707
Total	$	17,066	$	(3,473	)	$	13,593

As of March 31, 2016
Raw materials and components	$	10,556	$	(1,052	)	$	9,504

Finished goods	6,550		(956		)	5,594
Total	$	19,151	$	(2,127	)	$	17,024

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.

In fiscal 2017, Orion increased its obsolescence reserve by $1,346,000. The reserve was increased by $1,671,000 related to its fluorescent and LED exterior products. The reserve increase was reduced by disposals during the year of fully reserved inventory items along with other inventory related activities. Orion’s customer preference is for higher performing LED lighting technologies rather than lower-priced earlier generation solutions.

Property and Equipment

Property, Plant and Equipment [Abstract]

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.

Orion 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.

In fiscal 2017, no fixed asset impairment charges were required.

On June 30, 2016, Orion completed the sale of its Manitowoc manufacturing and distribution facility for gross cash proceeds of $2,600,000, which approximated the assets' net carrying values. In conjunction with the sale, Orion entered into an agreement with the buyer to leaseback approximately 197,000 square feet of the building for not less than three years, subject to mutual options to reduce the amount of leased space.

In conjunction with the anticipated sale of this facility, in fiscal 2016, the Company reviewed the carrying value of the manufacturing and distribution facility assets for impairment performing a probability weighted analysis of expected future cash flows. Based on that analysis, the Company concluded that the assets' carrying values were no longer supported. As such, Orion recorded an impairment charge of $1,614,000 in fiscal 2016 to write the assets down to their fair value, which approximates the expected selling price. The impairment charge was recorded to all three of Orion’s reportable segments as follows: Orion U.S. Markets $689,000, Orion Engineered Systems $804,000, and Orion Distribution Services $121,000.

In fiscal 2015, an impairment charge of $1,030,000 was recorded in connection with the assessment of carrying costs related to the wireless controls product offering.

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



	March 31, 2017			March 31, 2016
Land and land improvements	$	424		$	421
Buildings and building improvements	9,245			11,849

Equipment	$	581		408
Less: accumulated depreciation and amortization	(202		)	(65		)
Net equipment	$	379		$	343

Depreciation is recognized over the estimated useful lives of the respective assets, using the straight-line method. Orion recorded depreciation expense of $1,451,000, $2,950,000 and $2,853,000 for the years ended March 31, 2017, 2016 and 2015, respectively.

Depreciable lives by asset category are as follows:



Land improvements	10-15 years
Buildings and building improvements	10-39 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

No interest was capitalized for construction in progress during fiscal 2017 or fiscal 2016.

Goodwill and Other Intangible Assets

Goodwill and Intangible Assets Disclosure [Abstract]

GOODWILL AND OTHER INTANIGBLE ASSETS

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.

As of March 31, 2016 and March 31, 2017, Orion had no goodwill on its Consolidated Balance Sheet. Prior to March 31, 2016, Orion had allocated goodwill to its reporting units which were also two of its reportable segments as follows: $2,371,000 to the U.S. Markets ("USM") and $2,038,000 to Orion Engineered Systems ("OES"). The Orion Distribution Services ("ODS") segment had no goodwill. Orion tests goodwill for impairment at least annually as of the first day of the fiscal fourth quarter, or when indications of potential impairment exist. Orion performed its last annual goodwill impairment test as of January 1, 2016. In accordance with ASC 350, Intangibles - Goodwill and Other, Step 1 of the impairment test compares the fair value of the reporting unit with its carrying value. Orion determined the fair value of each reporting unit using a discounted cash flow method and the guideline public entity method. After completing a Step 1 evaluation, the estimated fair value of both reporting units was determined to be lower than their carrying values. As such, each unit failed Step 1 of the goodwill impairment test and Step 2 of the goodwill impairment test was performed. In conjunction with the Step 2 test, Orion performed a hypothetical purchase price allocation for each of its reporting units to determine the implied fair value of goodwill and compared the implied fair value of goodwill to the carrying amount of goodwill. A third-party valuation firm was engaged to assist in the Step 2 valuation process. The fair value determination was categorized as Level 3 in the fair value hierarchy (see “Fair Value of Financial Instruments” for the definition of Level 3 inputs). As a result of Step 2 of the goodwill impairment tests as of January 1, 2016, Orion’s USM segment recorded a goodwill impairment charge of $2,371,000 and Orion’s OES segment recorded a goodwill impairment charge of $2,038,000. Therefore, as of March 31, 2017 and March 31, 2016, Orion had no goodwill on its Consolidated Balance Sheets.

The change in the carrying value of goodwill during fiscal 2016 was as follows (dollars in thousands):



Balance at March 31, 2015	$	4,409
Impairments	(4,409		)
Balance at March 31, 2016	$	—

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

Intangible assets that have a definite life 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, 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.

Indefinite lived intangible assets are evaluated for impairment at least annually on the first day of Orion’s fiscal fourth quarter, or when indications of potential impairment exist. This annual impairment review may begin with a qualitative test to determine whether it is more likely than not that an indefinite lived intangible asset's carrying value is greater than its fair value. If the qualitative assessment reveals that asset impairment is more likely than not, a quantitative impairment test is performed comparing the fair value of the indefinite lived intangible asset to its carrying value. Alternatively, the qualitative test may be bypassed and the quantitative impairment test may be immediately performed. If the fair value of the indefinite lived intangible asset exceeds its carrying value, the indefinite lived intangible asset is not impaired and no further review is performed. If the carrying value of the indefinite lived intangible asset exceeds its fair value, an impairment loss would be recognized in an amount equal to such excess. Once an impairment loss is recognized, the adjusted carrying value becomes the new accounting basis of the indefinite lived intangible asset.

Orion performed a qualitative assessment in conjunction with its annual impairment test of its indefinite lived intangible assets as of January 1, 2017. This qualitative assessment considered Orion’s operating results for the first nine months of fiscal 2017 in comparison to prior years as well as its anticipated fourth quarter results and fiscal 2018 plan. As a result of the conditions that existed as of the assessment date, an asset impairment was not deemed to be more likely than not and a quantitative analysis was not required.

During the fourth quarter of fiscal 2017, Orion achieved lower than anticipated operating results, made a strategic shift in its manufacturing strategy and approach to the fluorescent and LED exterior lighting market, and revised its fiscal 2018 forecast. As a result, a triggering event occurred requiring the Company to reassess its indefinite lived intangible assets for impairment. As such Orion performed a quantitative impairment review of its indefinite lived intangible assets related to the Harris trade name applying the royalty replacement method to determine the asset’s fair value as of March 31, 2017. Under the royalty replacement method, the fair value of the Harris tradename was determined based on a market participant’s view of the royalty that would be paid to license the right to use the tradename. This quantitative analysis incorporated several assumptions including forecasted future revenues and cash flows, estimated royalty rate, based on similar licensing transactions and market royalty rates, and discount rate, which incorporates assumptions such as weighted-average cost of capital and risk premium. As a result of this impairment test, the carrying value of the Harris trade name exceeded its estimated fair value and an impairment of $250,000 was recorded to Impairment of assets during the fourth quarter to reduce the asset’s carrying value to its calculated fair value. This fair value determination was categorized as Level 3 in the fair value hierarchy (see “Fair Value of Financial Instruments” for the definition of Level 3 inputs).

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

Orion’s management periodically reviews the carrying value of patent applications and related costs. When a patent application is probable of being unsuccessful or a patent is no longer in use, Orion writes off the remaining carrying value as a charge to general and administrative expense within its Consolidated Statement of Operations. Such write-offs recorded in fiscal 2017, 2016 and 2015 were $0, $78,000 and $120,000, respectively.

Included in other income in fiscal 2017 are product royalties received from licensing agreements for our patents.

Net Income (Loss) per Common Share

Earnings Per Share [Abstract]

NET INCOME (LOSS) PER COMMON SHARE

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

Diluted net income (loss) per common share reflects the dilution that would occur if warrants and stock options were exercised and restricted shares vested. In the computation of diluted net income (loss) per common share, Orion uses the treasury stock method for outstanding options, warrants and restricted shares. Diluted net loss per common share is the same as basic net loss per common share for the years ended March 31, 2017, March 31, 2016 and March 31, 2015 because the effects of potentially dilutive securities would be anti-dilutive. The effect of net income (loss) per common share is calculated based upon the following shares:

Business Combinations [Abstract]
ACQUISITION	ACQUISITION On July 1, 2013, Orion acquired all of the equity interests of Harris Manufacturing, Inc. and Harris LED, LLC (collectively, "Harris"). Harris was a Florida-based lighting company which engineered, designed, sourced and manufactured energy-efficient lighting systems, including fluorescent and LED lighting solutions, and day-lighting products. The acquisition 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 Orion. The acquisition consideration paid to the Harris Shareholders was valued under the Purchase Agreement at an aggregate of $10,801,000, plus an adjustment of approximately $200,000 to reflect Orion's acquisition of net working capital in excess of a targeted amount, plus an additional $612,000 for the contingent consideration earn-out value assigned to non-employee Harris shareholders. On October 21, 2013, Orion executed a letter agreement amending the Purchase Agreement. The letter agreement established a fixed future consideration of $1,371,000 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, Orion issued $571,000, or 83,943 shares, of Orion's unregistered common stock. The fixed consideration was determined based upon the existing share calculation at a fair value of $3.80 per common share. On January 2, 2015, Orion would pay $800,000 in cash to settle all outstanding obligations related to the earn-out component of the Purchase Agreement. In December 2014, Orion amended the letter agreement to defer the January 2, 2015 payment of $800,000 in cash until February 13, 2015, to settle all outstanding obligations related to the earn-out component of the Purchase Agreement. The final payment was made on February 12, 2015. The Purchase Agreement contained customary representations and warranties, as well as indemnification obligations, and limitations thereon, by Orion and the Harris Shareholders. On December 31, 2014, Harris was merged with and into Orion. Orion recorded $612,000 for the non-employee Harris Shareholder portion of the contingent consideration liability on the acquisition date. During the year ended March 31, 2015, Orion expensed $147,000 in compensation expense as contingent consideration for employee Harris shareholders.

Revolving Credit Agreement

Orion has an amended credit agreement ("Credit Agreement") that provides for a revolving credit facility ("Credit Facility")subject to a borrowing base requirement based on eligible receivables and inventory. As of March 31, 2017 Orion's borrowing base was approximately $6,832,000. The Credit Facility has a maturity date of February 6, 2019 and includes a $2,000,000 sublimit for the issuance of letters of credit. As of March 31, 2017, Orion had no outstanding letters of credit. Borrowings outstanding as of March 31, 2017, amounted to approximately $6,629,000 and are included in non-current liabilities in the accompanying Consolidated Balance Sheet. Orion estimates that as of March 31, 2017, it was eligible to borrow an additional $203,000 under the Credit Facility based upon current levels of eligible inventory and accounts receivable.

Subject in each case to Orion's applicable borrowing base limitations, the Credit Agreement otherwise provides for a $15,000,000 Credit Facility. This limit may increase to $20,000,000 based on a borrowing base requirement, if Orion satisfies certain conditions. Orion did not meet the requirements to increase the borrowing limit to $20,000,000 as of July 31, 2016, the most recent measurement date.

From and after any increase in the Credit Facility limit from $15,000,000 to $20,000,000, the Credit Agreement requires that Orion 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 contains additional customary covenants, including certain restrictions on Orion’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 Orion’s stock, redeem or repurchase shares of Orion’s stock, or pledge or dispose of assets. Orion was in compliance with its covenants in the Credit Agreement as of March 31, 2017.

Each subsidiary of Orion 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 Orion’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 March 31, 2017, the interest rate was 4.15%. Orion 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.

Harris Seller's Note

On July 1, 2013, Orion issued an unsecured and subordinated promissory note in the principal amount of $3,124,000 to partially fund the acquisition of Harris Manufacturing, Inc. and Harris LED, LLC (collectively, "Harris"). The note is included in the table above as Harris seller's note. The notes interest rate was 4% per annum. Principal and interest were payable quarterly. The note matured in July 2016 and was paid in full upon maturity.

Equipment Lease Obligation

In March 2016 and June 2015, Orion entered into lease agreements with a financing company in the principal amount of $19,000 and $377,000, respectively, to fund certain equipment. The leases are secured by the related equipment. The leases bear interest at a rate of 5.94% and 3.6% and mature in February 2018 and June 2020. Both leases contain a one dollar buyout option.

Customer Equipment Finance Notes Payable

In December 2014, Orion entered into a secured borrowing agreement with a financing company in the principal amount of $446,000 to fund completed customer contracts under its OTA finance program that were previously funded under the OTA credit agreement. The loan amount is secured by the OTA-related equipment and the expected future monthly payments under the supporting 25 individual OTA customer contracts. The borrowing agreement bears interest at a rate of 8.36% and matures in April 2018.

In June 2011, Orion entered into a note agreement with a financial institution that provided Orion with $2,831,000 to fund completed customer contracts under Orion’s OTA finance program. This note is included in the table above as customer equipment finance notes payable in the prior year. The note is collateralized by the OTA-related equipment and the expected future monthly payments under the supporting 40 individual OTA contracts. The note bears interest at 7.85%. The note matured in April 2016 and was paid in full upon maturity.

Other Long-Term Debt

In September 2010, Orion entered into a note agreement with the Wisconsin Department of Commerce that provided Orion with $260,000 to fund Orion’s rooftop solar project at its Manitowoc manufacturing facility. This note is included in the table above as other long-term debt. The note is collateralized by the related solar equipment. The note allowed for two years without interest accruing or principal payments due. Beginning in July 2012, the note bears interest at 2% and require monthly payments of $4,600. The note matures in June 2017. The note agreement requires Orion to maintain a certain number of jobs at its Manitowoc facilities during the note’s duration. Orion was in compliance with all covenants in the note agreement as of March 31, 2017.

Orion 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 were recorded in fiscal 2017, fiscal 2016 and fiscal 2015, as a reduction in taxes payable and a credit to additional paid in capital based on the amount that was utilized in the current year.

As of March 31, 2017, Orion has federal net operating loss carryforwards of approximately $65,746,000, of which $2,977,000 are associated with the exercise of NQSOs that have not yet been recognized by Orion in its financial statements. Orion also has state net operating loss carry-forwards of approximately $56,231,000, of which $3,324,000 are associated with the exercise of NQSOs. Orion also has federal tax credit carry-forwards of approximately $1,403,000 and state tax credits of $724,000. Orion's net operating loss and tax credit carry-forwards will begin to expire in varying amounts between 2030 and 2037. For the fiscal year ended March 31, 2017, Orion has recorded a valuation allowance of $30,078,000, equaling the net deferred tax asset due to the uncertainty of its realization value in the future. For the fiscal years ended March 31, 2017 and March 31, 2016, the valuation allowance against Orion's net federal and net state deferred tax assets increased $4,627,000 and $5,740,000, respectively. Orion considers future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance. In the event that Orion 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 Orion'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, Orion's ability to use its net operating loss carry-forwards, 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 Orion. There was no limitation of net operating loss carry-forwards that occurred for fiscal 2017, fiscal 2016, or fiscal 2015.

Orion records its tax provision based on the respective tax rules and regulations for the jurisdictions in which it operates. Where Orion 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.

Orion files income tax returns in the United States federal jurisdiction and in several state jurisdictions. The Company's federal tax returns for tax years beginning April 1, 2013 or later are open. For states in which Orion files state income tax returns, the statue of limitations is generally open for tax years ended March 31, 2013 and forward.

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. Orion currently has no state income tax return positions in the process of examination, administrative appeals or litigation.

Orion has settled with the Wisconsin Department of Revenue with respect to an assessment regarding the proper classification of our products for tax purposes under Wisconsin law. The issue under review is whether the installation of our lighting systems is considered a real property construction activity under Wisconsin law. We have resolved this matter with the Wisconsin Department of Revenue in fiscal 2017 for the amount of $460,000.

Uncertain tax positions

As of March 31, 2017, the balance of gross unrecognized tax benefits was approximately $113,000, all of which would reduce Orion’s effective tax rate if recognized.

Orion 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. Orion recognizes penalties and interest related to uncertain tax liabilities in income tax expense. Penalties and interest are included in the unrecognized tax benefits. Orion had the following unrecognized tax benefit activity (dollars in thousands):

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS AND CONTINGENCIES

Operating Leases

Orion leases office space and equipment under operating leases expiring at various dates through 2020. Rent expense under operating leases was $854,000, $502,000 and $398,000 for fiscal 2017, 2016 and 2015, respectively. Total annual commitments under non-cancelable operating leases with terms in excess of one year at March 31, 2017 are as follows (dollars in thousand):



Fiscal 2018	$	654
Fiscal 2019	473
Fiscal 2020	114
	$	1,241

On March 1, 2016, Orion entered into a lease agreement as a lessor for excess office space at its corporate headquarters in Manitowoc, Wisconsin. The initial term of the lease is 24 months and the tenant has the option to extend the term for up to three additional twelve month periods. The monthly rental payment Orion receives is $21,000 and is included in general and administrative expenses.

On March 31, 2016, Orion entered into a purchase and sale agreement ("Agreement") with third party to sell and leaseback Orion's manufacturing and distribution facility for gross cash proceeds of $2,600,000. The transaction closed on June 30, 2016. Pursuant to the Agreement, a lease was entered into on June 30, 2016, in which Orion is leasing approximately 197,000 square feet of the building for not less than three years, with rent at $2.00 per square foot per annum. Orion's monthly payment under this lease is approximately $38,000. The lease contains options by either party to reduce the amount of leased space after March 1, 2017.

Purchase Commitments

Orion 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, 2017, Orion had entered into $4,218,000 of purchase commitments related to fiscal 2018 for inventory purchases.

Retirement Savings Plan

Orion 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 contributions by Orion. In fiscal 2017, 2016 and 2015, Orion made matching contributions of approximately $9,000, $10,000 and $23,000, respectively.

Litigation

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

On March 27, 2014, Orion was named as a defendant in a civil lawsuit filed by Neal R. Verfuerth, a 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 alleged, among other things, that Orion breached certain agreements entered into with the plaintiff, including the plaintiff’s employment agreement, and violated certain laws. The complaint sought, 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 Orion'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, Orion 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. At the court's direction, the parties attempted to mediate the matter in May 2016, but were unsuccessful in resolving the matter.

On August 25, 2016, the Chief Judge of the United States District Court for the Eastern District of Wisconsin (Green Bay Division) dismissed all claims against Orion brought by the plaintiff, including his claims that Orion had allegedly breached the plaintiff’s employment agreement and had allegedly violated the plaintiff's whistleblower rights. On September 22, 2016, the plaintiff filed an appeal to the United States Court of Appeals challenging the judgment rendered on August 25, 2016. After the court-mandated mediation was unsuccessful, the plaintiff moved forward with his appeal focusing only on the District Court's dismissal of his whistleblower claims.

Orion intends to continue to defend against the claims vigorously. Orion believes it has substantial legal and factual defenses to the claims and allegations remaining in the case and that Orion will prevail in this proceeding. Based upon the current status of the lawsuit, Orion does not believe that it is reasonably possible that the lawsuit will have a material adverse impact on its future continuing results of operations.

Orion negotiated a settlement with the Wisconsin Department of Revenue with respect to an assessment regarding the proper classification of its products for tax purposes under Wisconsin law. Orion resolved this matter with the Wisconsin Department of Revenue in June 2016 for $460,000.

Stockholders' Equity Note [Abstract]

SHAREHOLDERS' EQUITY

SHAREHOLDERS’ EQUITY

Common Stock Transactions

On February 20, 2015, Orion completed an underwritten public offering of 5,462,500 shares of its common stock, at an offering price to public of $3.50 per share. Net proceeds of the offering approximated $17,465,000.

Share Repurchase Program and Treasury Stock

In October 2011, Orion’s Board of Directors approved a share repurchase program authorizing Orion to repurchase in aggregate up to a maximum of $1,000,000 of Orion’s outstanding common stock. In November 2011, Orion’s Board of Directors approved an increase to the share repurchase program authorizing Orion to repurchase in aggregate up to a maximum of $2,500,000 of Orion’s outstanding common stock. In April 2012, Orion's Board approved another increase to the share repurchase program authorizing Orion to repurchase in aggregate up to a maximum of $7,500,000 of Orion's outstanding common stock. As of March 31, 2017, Orion had repurchased 3,022,349 shares of common stock at a cost of $6,791,000 under the program. Orion did not repurchase any shares in fiscal 2017, fiscal 2016 or fiscal 2015 and does not intend to repurchase any additional common stock under this program in the near-term.

Shareholder Rights Plan

On January 7, 2009, Orion’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 Orion’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 Orion one share of Orion’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 Orion’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 Orion’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 Orion’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, Orion 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 Orion. At any time prior to a person becoming an Acquiring Person, the Board of Directors of Orion 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, Orion’s Board of Directors approved a non-compensatory employee stock purchase plan, or ESPP. The ESPP authorizes 2,500,000 shares to be issued from treasury or authorized shares to satisfy employee share purchases under the ESPP. All full-time employees of Orion are eligible to be granted a non-transferable purchase right each calendar quarter to purchase directly from Orion up to $20,000 of Orion’s common stock at a purchase price equal to 100% of the closing sale price of Orion’s common stock on The NASDAQ Capital Market on the last trading day of each quarter. The ESPP allows for employee loans from Orion, 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 Orion’s shares purchased by the participant under the ESPP and Orion has full recourse against the employee, including offset against compensation payable. As of March 31, 2013, Orion had halted the loan program. Orion had the following shares issued from treasury during fiscal 2017 and fiscal 2016:



	As of March 31, 2017

No new loans were issued during the periods presented as the loan program was discontinued.

Stock Options, Restricted Shares and Warrants

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

STOCK OPTIONS, RESTRICTED SHARES AND WARRANTS

At Orion's 2016 Annual Meeting of Shareholders held on August 3, 2016, Orion's shareholders approved the Orion Energy Systems, Inc. 2016 Omnibus Incentive Plan (the "Plan"). The Plan authorizes grants of equity-based and incentive cash awards to eligible participants designated by the Plan's administrator. Awards under the Plan may consist of stock options, stock appreciation rights, performance shares, performance units, shares of Orion's common stock ("Common Stock"), restricted stock, restricted stock units, incentive awards or dividend equivalent units. An aggregate of 1,750,000 shares of Common Stock are reserved for issuance under the Plan.

Prior to shareholder approval of the Plan, the Company maintained its 2004 Stock and Incentive Awards Plan, as amended, which authorized the grant of cash and equity awards to employees (the “Former Plan”). No new awards will be granted under the Former Plan, however, all awards granted under the Former Plan that were outstanding as of August 3, 2016 will continue to be governed by the Former Plan. Forfeited awards originally issued under the Former Plan are canceled and are not available for subsequent issuance under the 2016 Omnibus Plan.

Certain non-employee directors have elected to receive stock awards in lieu of cash compensation pursuant to elections made under Orion’s non-employee director compensation program. The Plan and the Former Plan also permit accelerated vesting in the event of certain changes of control of Orion as well as under other special circumstances.

Orion historically granted stock options and restricted stock under the Former Plan. Orion has not issued stock options since fiscal 2014 and instead has issued restricted stock.

Orion accounts for stock-based compensation in accordance with ASC 718, Compensation - Stock Compensation. Under the fair value recognition provisions of ASC 718, 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

In fiscal 2017, an aggregate of 1,132,392 restricted shares were granted valued at a price per share between $1.35 and $2.22, which was the closing market price as of each grant date. In fiscal 2016, an aggregate of 795,805 restricted shares were granted valued at a price per share between $1.34 and $2.62, which was the closing market price as of each grant date. In fiscal 2015, an aggregate of 410,496 restricted shares were granted valued at a price per share between $4.16 and $7.23, which was the closing market price as of each grant date.

In fiscal 2017, Orion granted an aggregate of 53,501 shares from the 2004 Stock and Incentive Awards Plan and the 2016 Omnibus Incentive Plan to certain non-employee directors who elected to receive stock awards in lieu of cash compensation. The shares were valued ranging from $1.38 to $1.85 per share, the closing market price as of the issuance dates. In fiscal 2016, Orion granted 35,290 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 $1.20 to $2.62 per share, the closing market price as of the issuance dates. Additionally, during fiscal 2016, Orion issued 2,500 shares to a consultant as part of a consulting compensation agreement. The shares were valued at $2.00 per share, the closing market price as of the issuance date. In fiscal 2015, Orion granted 27,931 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 $4.20 to $5.23 per share, the closing market price as of the issuance dates.

On June 7, 2016, Orion issued and sold 57,065 shares of its common stock to an executive. On August 5, 2016, Orion sold an aggregate of 63,381 shares of its common stock, in equal amounts, to three recently retired members of Orion's board of directors. In each case above, the purchase price for the shares was calculated based on the closing price of Orion's common stock on the NASDAQ Capital Market of the date of the issuance. The shares of common stock were offered and sold pursuant to an exemption from the registration requirements of the Securities Act of 1933, as amended, pursuant to Section 4(2) and Rule 701.

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

Segment Reporting [Abstract]

SEGMENT DATA

Orion has the following business segments: Orion U.S. Markets Division ("USM"), Orion Engineered Services Division ("OES") and Orion Distribution Services Division ("ODS"). The accounting policies are the same for each business segment as they are on a consolidated basis. Business segment assets consist of all balance sheet assets except for cash and other long term assets which are grouped in Corporate and Other.

Orion U.S. Markets Division

Our USM segment sells commercial lighting systems and energy management systems to the wholesale contractor markets. USM customers include ESCOs and electrical contractors. During fiscal 2017, a significant portion of the historic sales of this division migrated to distribution channel sales as a result of the implementation of our distribution sales strategy. The migrated sales are included in Orion's ODS Division. We expect this migration to continue during fiscal 2018.

Orion Engineered Systems Division

The OES segment develops and sells lighting products and provides construction and engineering services for Orion's commercial lighting and energy management systems. OES provides turnkey solutions for large national accounts, governments, municipalities and schools.

Orion Distribution Services Division

The ODS segment focuses on selling lighting products through manufacturer representative agencies and a network of broadline North American distributors. This segment expanded in fiscal 2017 as a result of the expansion of sales through distributors as a result of the implementation of Orion's distribution sales strategy. This expansion included the migration of customers from direct sales previously included in Orion's USM division.

Corporate and Other

Corporate and Other is comprised of operating expenses not directly allocated to Orion’s segments and adjustments to reconcile to consolidated results.

Subsequent Events	12 Months Ended
Subsequent Events	Mar. 31, 2017
Subsequent Events [Abstract]
SUBSEQUENT EVENTS	SUBSEQUENT EVENTS Subsequent events are events or transactions that occur after the balance sheet date but before financial statements are issued. Recognized subsequent events are events or transactions that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements. Non-recognized subsequent events are events that provide evidence about conditions that did not exist at the date of the balance sheet but arose after that date. Management has reviewed events occurring through the date the financial statements were issued and noted the following event requiring disclosure. On May 25, 2017, Orion's Board of Directors restructured its management team. As part of this restructuring, Orion's Chief Executive Officer left the Company and its current Board Chair assumed the role of Chief Executive Officer. Orion estimates that the accrual needed for severance and other related costs for the departing CEO and other cost reduction initiatives because of the management change to be approximately $1,500,000 to $2,000,000. These costs are expected to be principally incurred in the first quarter of fiscal 2018.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
Summary of Significant Accounting Policies (Policies)	Mar. 31, 2017
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.
Reclassifications	Reclassifications Where appropriate, certain reclassifications have been made to prior years’ financial statements to conform to the current year presentation.
Use of Estimates	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 allowance for doubtful accounts, accruals for warranty and loss contingencies, income taxes and certain equity transactions. Accordingly, actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents Orion 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 Orion’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and other, revolving credit facility and long-term debt. The carrying amounts of Orion’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 debt and revolving credit facility, because of the interest rates currently available to Orion 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.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts Orion performs ongoing evaluations of its customers and continuously monitors collections and payments and estimate an allowance for doubtful accounts based upon the aging of the underlying receivables, historical experience with write-offs and specific customer collection issues that have been identified.
Long-Term Receivables	Long-Term Receivables Orion 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. Orion uses the implied cost of capital from each individual contract as the discount rate.
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.
Incentive Compensation	Incentive Compensation Orion’s compensation committee approved an Executive Fiscal Year 2017 Annual Cash Incentive Program under its 2004 Stock and Incentive Plan. The plan provided for performance cash bonus payments ranging from 35-100% of the fiscal 2017 base salaries of Orion’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 2017 of at least (i) $500,000 of profit before taxes and (ii) revenue growth of 10% more than fiscal year 2016. Based upon the results for the year ended March 31, 2017, Orion did not accrue any expense related to this plan. Orion’s compensation committee approved an Executive Fiscal Year 2016 Annual Cash Incentive Program under its 2004 Stock and Incentive Awards Plan. The plan provided for performance cash bonus payments ranging from 35-100% of the fiscal 2016 base salaries of Orion’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 2016 of at least (i) $110,000 of profit before taxes and (ii) revenue growth of 10% more than fiscal year 2015. Based upon the results for the year ended March 31, 2016, Orion did not accrue any expense related to this plan. Orion’s compensation committee approved an Executive Fiscal Year 2015 Annual Cash Incentive Program under its 2004 Stock and Incentive Awards Plan. The plan provided for performance cash bonus payments ranging from 35-100% of the fiscal 2015 base salaries of Orion’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 2015 of at least (i) $2,300,000 of profit before taxes and (ii) revenue of at least $90,400,000. Based upon the results for the year ended March 31, 2015, Orion did not accrue any expense related to this plan.
Revenue Recognition	Revenue Recognition Revenue is recognized on the sales of Orion's lighting and related energy-efficiency systems and products when the following four criteria are met: 1.persuasive evidence of an arrangement exists; 2.delivery has occurred and title has passed to the customer; 3.the sales price is fixed and determinable and no further obligation exists; and 4.collectability is reasonably assured. These four criteria are met for Orion’s product-only revenue upon delivery of the product and title passing to the customer. At that time, Orion 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 Orion’s lighting and energy management technologies under multiple element arrangements, consisting of a combination of product sales and services, Orion 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, Orion 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 Orion determines estimated selling price is provided below). The nature of Orion’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, Orion establishes the selling price for its energy management system products using management's best estimate of the selling price, as VSOE and TPE do not exist. Product revenue is recognized when title and risk of loss for the products transfers. For product revenue, management's best estimate of selling price is determined using a cost plus gross profit margin method. In addition, Orion records in service revenue the selling price for its installation and recycling services using management’s best estimate of selling price, as VSOE and TPE do 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. Orion’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 and TPE do 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 Orion's installation and recycling services, under a multiple-element arrangement, management’s best estimate of selling price is determined using a cost plus gross profit margin method with consideraion given to other relevant economic conditions and trends, customer demand, pricing practices, and margin objectives. The determination of an estimated selling price is made through consultation with and approval by management, taking into account the preceding factors. Orion offers a financing program, called an Orion Throughput Agreement, or OTA, for a customer’s lease of Orion’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 Orion’s net investment in the lease, which typically is the net present value of the future cash flows. Orion has limited Power Purchase Agreement (“PPA”) contracts still outstanding. Those PPA’s outstanding are supply side agreements for the generation of electricity for which we recognize revenue on a monthly basis over the life of the PPA contract, typically in excess of 10 years. Prior to fiscal 2015, Orion sold solar PV systems which were recognized to revenue using the percentage-of-completion method by measuring project progress by the percentage of costs incurred to date of the total estimated costs for each contract as materials are installed. Revenue from sales of Orion's solar PV systems is generally recognized over a period of three to 15 months. There were no sales of solar PV systems in fiscal 2017, fiscal 2016 or fiscal 2015. Deferred revenue relates to advance customer billings, investment tax grants received related to PPAs and long term maintenance contracts on OTAs and is classified as a liability on the condensed 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 Orion 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 Advertising costs of $94,000, $4,000 and $149,000 for fiscal 2017, 2016 and 2015, respectively, were charged to operations as incurred.
Research and Development	Research and Development Orion expenses research and development costs as incurred. Amounts are included in the Statement of Operations and Comprehensive Income on the line item Research and development.
Income Taxes	Income Taxes Orion 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 carry-forwards. 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, 2017, Orion recorded a full valuation allowance of $4,627,000 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. Orion 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. Orion 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.
Stock Based Compensation	Stock Based Compensation Orion’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. Orion realized no such tax benefits during the years ended March 31, 2017, 2016 and 2015. Historically, Orion uses the Black-Scholes option-pricing model for issued stock options. Orion calculated 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 was based upon the vesting term of Orion’s options and expected exercise behavior. Orion accounts for stock-based compensation in accordance with ASC 718, Compensation - Stock Compensation. Under the fair value recognition provisions of ASC 718, 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 9, Orion currently awards non-vested restricted stock to employees, executive officers and directors. Orion did not issue any stock options during fiscal 2017, fiscal 2016 or fiscal 2015. Orion has not paid dividends in the past and does not plan to pay any dividends in the foreseeable future. Orion estimates its forfeiture rate of unvested stock awards based on historical experience.
Concentration of Credit Risk and Other Risks and Uncertainties	Concentration of Credit Risk and Other Risks and Uncertainties Orion’s cash is deposited with two financial institutions. At times, deposits in these institutions exceed the amount of insurance provided on such deposits. Orion has not experienced any losses in such accounts and believes that it is not exposed to any significant financial institution viability risk on these balances. Orion purchases components necessary for its lighting products, including ballasts, lamps and LED components, from multiple suppliers.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Issued: Not Yet Adopted In August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-15, "Classification of Certain Cash Receipts and Cash Payments," which provides clarification and additional guidance as to the presentation and classification of certain cash receipts and cash payments in the statement of cash flows. The ASU provides guidance, as to the classification of a number of transactions including: contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, and distributions received from equity method investees. The new standard will be effective for Orion in the first quarter of fiscal 2019 and will be applied through retrospective adjustment to all periods presented. Orion does not expect the adoption of this guidance to have a material impact on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Subtopic 842)." This ASU requires that lessees recognize right-of-use assets and liabilities on the balance sheet for the rights and obligations created by long-term leases and disclose additional quantitative and qualitative information about leasing arrangements. Under this ASU, leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition. Similarly, lessors will be required to classify leases as sales-type, finance or operating leases, with classification affecting the pattern of income recognition. Classification for both lessees and lessors will be based on an assessment of whether risks and rewards as well as substantive control have been transferred through the lease contract. This ASU also provides guidance on the presentation of the effects of leases in the income statement and statement of cash flows. This guidance will be effective for Orion on April 1, 2019. Early adoption of the standard is permitted and a modified retrospective transition approach is required for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company has not yet completed its review of the full provisions of this standard against its outstanding lease arrangements and is in the process of quantifying the lease liability and related right of use asset which will be recorded to its consolidated balance sheets upon adoption of the standard. In addition, management continues to assess the impact of adoption of this standard on its consolidated statements of operations, cash flows, and the related footnote disclosures. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers." This ASU is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of 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 addition, the ASU requires enhanced and expanded financial statement disclosures. Since the issuance of this ASU, the FASB has issued further ASU’s to provide additional guidance and clarification as to the application of ASU 2014-09 and delaying its original effective date. The ASU allows companies to elect either a full retrospective or modified retrospective approach to adoption. Orion will adopt ASU 2014-09 and the related updates with their effective date on April 1, 2018. Orion has begun the process of implementing this standard, including performing a review of its revenue streams to identify any differences in the timing, measurement, or presentation of revenue recognition. The Company is in the process of reviewing the provisions of these standards against its customer contracts, including evaluating and identifying distinct performance obligations. The Company continues to evaluate its customer contracts to determine the impact on the timing and presentation of revenue. In addition, the Company is evaluating any necessary changes to its revenue related processes and controls as a result of the new standard, including the related footnote disclosures. Under ASU 2014-09 incremental contract costs, including sales commissions, may be required to be capitalized and expensed over the period these costs are recovered. Although Orion incurs commission costs, its contracts are typically completed within one year. As such, the Company will elect to apply the practical expedient for contract costs recovered within one year and will continue to recognize commissions as cost of sales immediately rather than capitalizing and expensing these costs over the contract period. Orion currently plans to elect the modified retrospective adoption method but continues to evaluate both of the available transition methods. In November 2015, the FASB issued ASU 2015-17, “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes,” to simplify the presentation of deferred taxes. The amendments in this update require that deferred tax assets and liabilities be classified as non-current on the balance sheet. This ASU is effective for Orion's annual reporting period, and interim periods therein, as of April 1, 2017. The adoption of this standard will have no impact on Orion’s consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory,” which changes the measurement principle for inventory from the lower of cost or market to the lower of cost or net realizable value for entities that measure inventory using first-in, first-out ("FIFO") or average cost. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This ASU is effective for Orion on April 1, 2017. The Company believes the adoption of this standard will not have a material impact on Orion’s consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting," which changes how companies account for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as the classification of related matters in the statement of cash flows. The ASU is effective for Orion as of April 1, 2017. The adoption of this standard is not expected to have a material impact on Orion’s consolidated financial statements. Recently Adopted Standards As of April 1, 2016, Orion adopted the provisions of ASU 2015-03 “Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs” and the related ASU 2015-15 “Interest-Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line of Credit Arrangements- Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting (SEC Update).” This guidance requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a reduction of the carrying amount of that debt liability, consistent with debt discounts, with the exception of debt issuance costs associated with line of credit agreements which may remain classified as an asset and amortized ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. As Orion’s only deferred debt issuance costs relate to its revolving line of credit, upon adoption of these standards a reclassification of the deferred financing costs was not required and there was no impact on Orion’s condensed consolidated financial statements. In August 2014, the FASB issued ASU 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 prescribes the necessary disclosures. Orion incorporated the provisions of this standard in performing its going concern analysis as of March 31, 2017. The adoption of this standard did not have an impact on Orion’s consolidated financial statements or footnote disclosures.
