Cash Equivalents  The Company considers only those investments that are highly liquid and readily convertible to cash with original maturities of three months or less at date of purchase as cash equivalents.

Accounts Receivable  Trade accounts receivable are recorded at the invoiced amount and are typically non‑interest bearing. The Company maintains allowances for estimated losses resulting from the inability of customers to make required payments and other accounts receivable allowances. Changes in the accounts receivable allowances are as follows as of March 31, 2017 and 2016 (in thousands):

 

Depreciation and Amortization  Depreciation and amortization are provided for using the straight-line method over the estimated useful lives of the related assets, ranging from two to ten years. Leasehold improvements are amortized over the lease term or the estimated useful lives of the assets, whichever is shorter. Intangible assets that have finite useful lives are amortized over their estimated useful lives using the straight-line method with the exception of the backlog of 100 kW microturbines (“TA100”) acquired from Calnetix Power Solutions, Inc. (“CPS”). Purchased backlog is amortized based on unit sales and presented as a component of cost of goods sold.

Deferred Revenue  Deferred revenue consists of deferred product and service revenue and customer deposits. Deferred revenue will be recognized when earned in accordance with the Company’s revenue recognition policy. The Company has the right to retain all or part of customer deposits under certain conditions.

Warranty  The Company provides for the estimated costs of warranties at the time revenue is recognized. The specific terms and conditions of those warranties vary depending upon the product sold and geography of sale. The Company’s product warranties generally start from the delivery date and continue for up to twenty-four months. Factors that affect the Company’s warranty obligation include product failure rates, anticipated hours of product operations and costs of repair or replacement in correcting product failures. These factors are estimates that may change based on new information that becomes available each period. Similarly, the Company also accrues the estimated costs to address reliability repairs on products no longer in warranty when, in the Company’s judgment, and in accordance with a specific plan developed by the Company, it is prudent to provide such repairs. The Company assesses the adequacy of recorded warranty liabilities quarterly and makes adjustments to the liability as necessary. When the Company has sufficient evidence that product changes are altering the historical failure occurrence rates, the impact of such changes is then taken into account in estimating future warranty liabilities.

Income Taxes  Deferred income tax assets and liabilities are computed for differences between the consolidated financial statement and income tax basis of assets and liabilities. Such deferred income tax asset and liability computations are based on enacted tax laws and rates applicable to periods in which the differences are expected to reverse. Valuation allowances are established, when necessary, to reduce deferred income tax assets to the amounts expected to be realized.

Risk Concentrations  Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. At March 31, 2017, the majority of our cash balances were held at financial institutions located in California. The accounts at these institutions are insured by the Federal Deposit Insurance Corporation up to certain limits. Balances that exceed the insurance coverage aggregate to approximately $19.0 million as of March 31, 2017. The Company places its cash and cash equivalents with high credit quality institutions. The Company performs ongoing credit evaluations of its customers and maintains an allowance for potential credit losses.

Sales to E‑Finity Distributed Generation, LLC (“E‑Finity), one of the Company’s domestic distributors, accounted for 14% and 11% of our revenue for the fiscal years ended March 31, 2017 and 2016. Sales to Horizon Power Systems (“Horizon”), one of the Company’s domestic distributors, accounted for 11%, and 15% of our revenue for the fiscal year ended March 31, 2017 and 2016, respectively. Sales to Dtc Soluciones Inmobiliarias S.A. de C.V. (“DTC”), one of the Company’s Mexican distributors, accounted for 10% of revenue for the fiscal year ended March 31, 2016. Sales to Optimal Group Australia Pty Ltd (“Optimal”), one of the Company’s Australian distributors, accounted for 10% of revenue for the fiscal year ended March 31, 2016. Additionally, E-Finity, DTC and Reliable Secure Power Systems, one of the Company’s domestic distributors (“RSP”), accounted for 29%,  12% and 10%, respectively, of net accounts receivable as of March 31, 2017. DTC, Optimal, RSP, and Regale Energy Zrt, the Company’s Hungarian distributor (“Regale”), accounted for 28%,  11%,  10% and 10%, respectively, of net accounts receivable as of March 31, 2016.

The Company recorded bad debt recovery of approximately $1.5 million for each of the fiscal years ended March 31, 2017 and 2016. During the fiscal year ended March 31, 2015, the Company recorded approximately $7.1 million and $2.6 million with respect to the accounts receivable allowances from BPC Engineering (“BPC”), one of the Company’s Russian distributors and Electro Mecanique Industries (“EMI”), one of the Company’s distributors in the Middle East and Africa, respectively.

Certain components of the Company’s products are available from a limited number of suppliers. An interruption in supply could cause a delay in manufacturing, which would affect operating results adversely.

Net Loss Per Common Share  Basic loss per common share is computed using the weighted‑average number of common shares outstanding for the period. Diluted loss per share is also computed without consideration to potentially dilutive instruments because the Company incurred losses which would make such instruments antidilutive. Outstanding stock options at March 31, 2017 and 2016 were 0.3 million and 0.5 million, respectively. Outstanding restricted stock units at each of March 31, 2017 and 2016 were 0.3 million. As of March 31, 2017, the number of warrants excluded from diluted net loss per common share computations was approximately 10.4 million. As of March 31, 2016, the Company did not have any warrants outstanding.

Evaluation of Ability to Maintain Current Level of Operations In connection with preparing the consolidated financial statements for the fiscal year ended March 31, 2017, management evaluated whether there were conditions and events, considered in the aggregate, that raised substantial doubt about the Company’s ability to meet its obligations as they became due for the next twelve months from the date of issuance of its Fiscal 2017 financial statements. Management assessed that there were such conditions and events, including a history of recurring operating losses, negative cash flows from operating activities, the continued negative impact caused by the volatility of the global oil and gas markets, a strong U.S. dollar (making our products more expensive overseas) and ongoing geopolitical tensions in Russia, North Africa and the Middle East. The Company’s working capital requirements during the fiscal year ended March 31, 2017 were higher than planned, primarily as a result of warranty claims related to the proactive retrofit for non-Signature Series C200 microturbines. Additionally, the Company did not fully achieve its planned number of product shipments during the fiscal year ended March 31, 2017, resulting in lower than expected revenue. The Company incurred a net loss of $23.9 million and used cash in operating activities of $18.5 million during the fiscal year ended March 31, 2017. In addition, as of March 31, 2017, the Company had cash, cash equivalents and restricted cash of $19.7 million, and outstanding borrowings under its credit facility of $11.5 million.

Management evaluated these conditions in relation to the Company’s ability to meet its obligations as they become due. The Company’s ability to continue current operations and to execute on management’s plans is dependent on its ability to generate cash flows from operations. Management believes that the Company will continue to make progress on its path to profitability by continuing to lower its operating costs and to develop its geographical and vertical markets.  The Company may seek to raise funds by selling additional securities (through the at-the-market offering or otherwise) to the public or to selected investors or by obtaining additional debt financing. There is no assurance that the Company will be able to obtain additional funds on commercially favorable terms or at all. If the Company raises additional funds by issuing additional equity or convertible debt securities, the fully diluted ownership percentages of existing stockholders will be reduced. In addition, any equity or debt securities that the Company would issue may have rights, preferences or privileges senior to those of the holders of its common stock. 

On June 2, 2017, the Company, entered into two secured credit facilities (the “Bridge Bank Credit Agreements”) with Western Alliance Bank through its Bridge Bank division (“Bridge Bank”), with credit support provided by the Export-Import Bank of the United States through its working capital guarantee program. Under the terms of the Bridge Bank Credit Agreements, the Company may borrow up to $12.0 million on a revolving basis depending on, among other factors, the amount of its eligible inventory and accounts receivable. The Bridge Bank Credit Agreements are for a two-year period ending June 2, 2019. See Note 11—Revolving Credit Facility, for discussion of the credit facilities with Bridge Bank.

The Company maintained two Credit and Security Agreements, with Wells Fargo Bank, National Association (“Wells Fargo”), which provided the Company with a credit facility up to $20.0 million in the aggregate. Upon closing with Bridge Bank the Company’s existing credit facilities with Wells Fargo, were paid off in full.

Based on the Company’s current operating plan, management anticipates that, given current working capital levels, current financial projections, the ability to borrow under its credit facility with Bridge Bank and the funds raised by selling additional securities through the at-the-market offering as of the date of issuance of its Fiscal 2017 financial statements, the Company will be able to meet its financial obligations as they become due over the next twelve months from the date of issuance of its Fiscal 2017 financial statements. 

Recent Accounting Pronouncements In November 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash” (“ASU 2016-18”), which amends guidance and presentation related to restricted cash in the statement of cash flows, including stating that amounts generally described as restricted cash and restricted cash equivalents should be included within cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown in the statement of cash flows. ASU 2016-18 is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods. The Company adopted ASU 2016-18 for the fiscal year ended March 31, 2017, and retrospectively applied ASU 2016-18 as required.

Prior to the adopting ASU No. 2016-18, the Company’s consolidated statements of cash flows reported changes in restricted cash as financing activities and excluded restricted cash from the beginning and ending balances of cash and cash equivalents. The effect on prior periods of adopting the new guidance includes: (i) increase in cash, cash equivalents, and restricted cash balance as of March 31, 2016 to $16.7 million and (ii) increase of $5.0 million in cash flows used in financing activities for the fiscal year ended March 31, 2016. The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported on the consolidated balance sheets that sum to amounts reported on the consolidated statements of cash flows (in thousands):

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). ASU 2016-09 changes certain aspects of accounting for share-based payments to employees and involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Specifically, ASU 2016-09 requires that all income tax effects of share-based awards be recognized as income tax expense or benefit in the reporting period in which they occur. Additionally, ASU 2016-09 amends existing guidance to allow forfeitures of share-based awards to be recognized as they occur. Previous guidance required that share-based compensation expense include an estimate of forfeitures. The Company has elected to early adopt ASU 2016-09 as of April 1, 2016 and made a policy election to account for forfeitures as they occur.  As of March 31, 2016, the Company had $11.2 million of unrealized excess tax benefits associated with share-based compensation. As a result of the adoption of ASU 2016-09 the Company recognized these tax benefits as a credit to retained earnings and a debit to the deferred tax asset. See Note 8—Income Taxes for further discussion on changes as a result of the adoption of ASU 2016-09. Other than these reclassifications, the effect of excess tax benefits on the provision for income taxes, and the adjustment to retained earnings, the Company does not believe the adoption of ASU 2016-09 will materially impact its consolidated financial position and results of operations.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), (“ASU 2016-02”). The purpose of ASU 2016-02 is to provide financial statement users a better understanding of the amount, timing, and uncertainty of cash flows arising from leases. The adoption of ASU 2016-02 will result in the recognition of a right-of-use asset and a lease liability for most operating leases. New disclosure requirements include qualitative and quantitative information about the amounts recorded in the financial statements. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018. ASU 2016-02 requires a modified retrospective transition by means of a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year in which the guidance is effective with the option to elect certain practical expedients. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2016-02 on its consolidated financial position and results of operations.

In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory (“ASU 2015-11”). ASU 2015-11 requires inventory that is recorded using the first-in, first-out method to be measured at the lower of cost or net realizable value. ASU 2015-11 is effective for annual and interim periods beginning after December 15, 2016, and should be applied prospectively with early adoption permitted at the beginning of an interim or annual reporting period. The Company does not believe that the provisions of ASU 2015-11 will have a material effect on its consolidated financial position or results of operations.

In April 2015, the FASB issued ASU 2015-03, Interest – Imputation of Interest (Subtopic 835-30). The ASU was issued as part of FASB’s current plan to simplify overly complex standards. This ASU requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. The recognition and measurement guidance for debt issuance costs are not affected by this ASU. The update requires retrospective application to all prior period amounts presented. This update is effective for annual and interim periods beginning on or after December 15, 2015, with early application permitted for financial statements that have not been issued. The Company adopted ASU 2015-03 with no impact on its consolidated financial position or results of operations.

In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”). ASU 2014-15 requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued and provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. Certain disclosures will be required if conditions give rise to substantial doubt about an entity’s ability to continue as a going concern. The amendments in ASU 2014-15 are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The Company adopted ASU 2014-15 with no impact on its consolidated financial position or results of operations.

Revenue Recognition Related ASUs:

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). ASU 2014-09 supersedes nearly all existing revenue recognition guidance under GAAP. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services.

In August 2015, the FASB issued FASB ASU No. 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date (“ASU 2014-09”), which deferred the effective date of ASU 2014-09 by one year. ASU 2014-09 is now effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, using one of two retrospective application methods. Early application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period.

In March 2016, the FASB issued FASB ASU No. 2016-08, Revenue from Contracts with Customers: Principal versus Agent Considerations (“ASU 2016-08”). ASU 2016-08 clarifies the implementation guidance on principal versus agent considerations.

In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing (“ASU 2016-10”). ASU 2016-10 clarifies the implementation guidance for identifying performance obligations and determining when to recognize revenue on licensing agreements for intellectual property.

In May 2016, the FASB issued ASU No. 2016-11, Revenue Recognition and Derivatives and Hedging: Rescission of SEC Guidance Because of ASU 2014-09 and ASU 2014-16 Pursuant to Staff Announcements at the March 3, 2016 EITF Meeting (“ASU 2016-11”). ASU 2016-11 rescinds certain SEC staff comments previously made in regard to these ASU’s.

In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients (“ASU 2016-12”) that provide guidance on assessing collectability, presentation of sales taxes, noncash consideration, and completed contracts and contract modifications at transition.

In December 2016, the FASB issued ASU 2016-20, Technical Corrections and Improvements to ASU 2014-09. The amendments in ASU 2014-09 affect narrow aspects of the guidance in ASU 2014-09, which is not yet effective. The amendments in ASU 2014-09 address loan guarantee fees, impairment testing of contract costs, provisions for losses on construction-type and production-type contracts, and various disclosures.

The Company is evaluating its existing revenue recognition policies and the impact of ASU 2014-09, ASU 2015-14, ASU 2016-08, ASU 2016- 10, ASU 2016-11, ASU 2016-12 and ASU 2016-20, if any, on its financial position and results of operations. The effective date and transition requirements for the amendments are the same as the effective date and transition requirements for ASU 2014-09. The Company will be required to adopt the revenue recognition standard in annual reporting periods beginning after December 15, 2017 (fiscal year ending March 31, 2019) and interim periods within those annual periods.
