2. Summary of Significant Accounting Policies

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.

Restricted Cash As a condition of the two secured credit facilities (the “Bridge Bank Credit Agreements”) with Western Alliance Bank through its Bridge Bank division (“Bridge Bank”) the Company has restricted $5.0 million of cash equivalents as additional security for the credit facility.

Fair Value of Financial Instruments  The carrying value of certain financial instruments, including cash equivalents, accounts receivable, accounts payable, revolving credit facility and notes payable approximate fair market value based on their short‑term nature. See Note 10—Fair Value Measurements, for disclosure regarding the fair value of other financial instruments.

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, 2018 and 2017 (in thousands):

Inventories  The Company values inventories at the lower of cost (determined on a first in first out (“FIFO”) basis) or net realizable value. The composition of inventory is routinely evaluated to identify slow-moving, excess, obsolete or otherwise impaired inventories. Inventories identified as impaired are evaluated to determine if write-downs are required. Included in the assessment is a review for obsolescence as a result of engineering changes in the Company’s products. All inventories expected to be used in more than one year are classified as long-term.

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 is presented as a component of cost of goods sold.

Long-Lived Assets  The Company reviews the recoverability of long-lived assets, including intangible assets with finite lives, whenever events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. If the expected future cash flows from the use of such assets (undiscounted and without interest charges) are less than the carrying value, the Company may be required to record a write‑down, which is determined based on the difference between the carrying value of the assets and their estimated fair value. The Company performed an analysis as of March 31, 2018 and determined that no impairment was necessary. See Note 5—Intangible Assets.

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.

Revenue  The Company’s revenue consists of sales of products, parts, accessories and service, which includes a comprehensive Factory Protection Plan (“FPP”), net of discounts. Capstone’s distributors purchase products, parts and FPPs for sale to end users and are also required to provide a variety of additional services, including application engineering, installation, commissioning and post‑commissioning repair and maintenance service. The Company’s standard terms of sales to distributors and direct end‑users include transfer of title, care, custody and control at the point of shipment, payment terms ranging from full payment in advance of shipment to payment in 90 days, no right of return or exchange, and no post‑shipment performance obligations by Capstone except for warranties provided on the products and parts sold.

Revenue from the sale of products, parts and accessories is generally recognized and earned when all of the following criteria are satisfied: (a) persuasive evidence of a sales arrangement exists; (b) price is fixed or determinable; (c) collectability is reasonably assured; and (d) delivery has occurred. Delivery generally occurs when the title and the risks and rewards of ownership have substantially transferred to the customer. Assuming all other revenue recognition criteria have been met, if it is determined that collection is not reasonably assured, revenue will not be recognized until collectability is reasonably assured, which is generally upon receipt of payment. Management’s estimates regarding the collectability of a particular sale may impact the timing of actual revenue recognized each period.

Service performed by the Company has consisted primarily of time and materials based contracts. The time and materials contracts are usually related to out‑of‑warranty units. Service revenue derived from time and materials contracts is recognized as the service is performed. The Company also provides maintenance service contracts to customers of its existing installed base. The maintenance service contracts are agreements to perform certain services to maintain a product for a specified period of time. Service revenue derived from maintenance service contracts is recognized on a straight‑line basis over the contract period. Effective January 1, 2018, the Company launched its Distributor Support System (“DSS program”) to fund additional support for distributor business development activities, customer lead generation, brand awareness and tailored marketing services for each of our major geography and market vertical. Service revenue derived from DSS program began in March 2018 and is recognized on a pro rata basis as the distributors purchase our products.

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.

Research and Development (“R&D”)  The Company accounts for grant distributions and development funding as offsets to R&D expenses and both are recorded as the related costs are incurred. There were no offsets to R&D during the fiscal years ended March 31, 2018 and 2017.

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.

Contingencies  The Company records an estimated loss from a loss contingency when information available prior to issuance of its financial statements indicates that it is probable that an asset has been impaired or a liability has been incurred at the date of the financial statements and the amount of the loss can be reasonably estimated.

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, 2018, 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 $19.2 million as of March 31, 2018. 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 16% and 14% of the Company’s revenue for the fiscal years ended March 31, 2018 and 2017, respectively. Sales to Horizon Power Systems (“Horizon”), one of the Company’s domestic distributors, accounted for 11% of the Company’s revenue for the fiscal year ended March 31, 2017. Additionally, Serba Dinamik Sdn Bhd (“Serba”), one of the Company’s Malaysian distributors, E-Finity, and Supernova Energy Services SAS (“Supernova”), one of the Company’s Colombian distributors, accounted for 20%,  18% and 10%, respectively, of net accounts receivable as of March 31, 2018. E-Finity, DTC Soluciones Inmobiliarias S.A. de C.V. (“DTC”), one of the Company’s Mexican distributors and Reliable Secure Power Systems (“RSP”), one of the Company’s domestic distributors, accounted for 29%,  12% and 10%, respectively, of net accounts receivable as of March 31, 2017.

On October 13, 2017, the Company entered into an Accounts Receivable Assignment Agreement (the “Assignment Agreement”) and Promissory Note (the “Note”) with Turbine International, LLC (“TI”). 

Pursuant to the terms of the Assignment Agreement, the Company agreed to assign to TI the right, title and interest to receivables owed to the Company from BPC Engineering, its former Russian distributor (“BPC”), upon TI’s payment to the Company of $2.5 million in three payments by February 1, 2018. The Company received payments from TI of approximately $0.3 million and $1.0 million under the Assignment Agreement during the three and twelve months ended March 31, 2018, respectively which was recorded as bad debt recovery. The receivables owed to the Company from BPC had a balance of $5.3 million as of March 31, 2018, and this balance was fully reserved. As of March 31, 2018, the right, title and interest to the accounts receivables owed to the Company from BPC had not been assigned to TI, as TI had not yet made all payments as required under the Assignment Agreement by February 1, 2018.

In connection with the terms of the Note, the Company granted TI the sole distribution rights for its products and services in the Russian oil and gas sector. As a result of this appointment, TI agreed to pay the Company $3.8 million over a three-year period in 35 equal monthly installments starting in August 2018.

On October 13, 2017, the Company and Hispania Petroleum, S.A. (the “Guarantor”), entered into a Guaranty Agreement (the “Guaranty Agreement”) whereby the Guarantor guarantees TI’s obligations under the Agreement and Note. However, due to the Company’s limited business relationship with TI and the missed payments on the Assignment Agreement, the Company deferred recognition of the Assignment Agreement and Note until collectability is reasonably assured.   

On June 5, 2018, the Company entered into an amendment to the Assignment Agreement (the “Amended Assignment Agreement”) and the Note (the “Amended Note”) with TI. Pursuant to the terms of the Amended Assignment Agreement, the right, title and interest to receivables owed to the Company from BPC will be contingent upon TI’s payment to the Company of the remaining approximately $1.5 million in five payments by September 20, 2019. Under the terms of the Amended Note, TI agreed to pay the Company $3.8 million over a three-year period in 13 equal quarterly installments starting in December 20, 2019. See Note 15—Subsequent Events for discussion with respect to an amendment to the Assignment Agreement and Note.

The Company recorded bad debt recoveries of approximately $1.1 million and $1.5 million for the fiscal years ended March 31, 2018 and 2017, respectively. As of March 31, 2015, the Company had an amount owed of approximately $8.1 million by BPC.  As of March 31, 2018, the Company collected cumulatively approximately $1.8 million from BPC on their accounts receivable allowance. Additionally, the Company collected approximately $1.0 million from TI, under the terms of the Assignment Agreement. The remaining balance is $5.3 million as of March 31, 2018 and this balance was fully reserved.

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.

Estimates and Assumptions  The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make certain estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Significant estimates include accounting for accounts receivable allowances, stock‑based compensation, inventory write‑downs, valuation of long‑lived assets including intangible assets with finite lives, product warranties, income taxes and other contingencies. Actual results could differ from those estimates.

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, 2018 and 2017 were 0.2 million and 0.3 million, respectively. Outstanding restricted stock units at March 31, 2018 and 2017 were 2.0 million and 0.3 million, respectively. As of March 31, 2018 and 2017, the number of warrants excluded from diluted net loss per common share computations was approximately 8.5 million and 10.4 million, respectively.

Stock‑Based Compensation  Options or stock awards are recorded at their estimated fair value at the measurement date. The Company recognizes compensation cost for options and stock awards that have a graded vesting schedule on a straight‑line basis over the requisite service period for the entire award.

Evaluation of Ability to Maintain Current Level of Operations In connection with preparing the consolidated financial statements for the fiscal year ended March 31, 2018, 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 2018 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 impact of the volatility of the global oil and gas markets, a strong U.S. dollar in certain markets making our products more expensive in such markets and ongoing global geopolitical tensions. The Company’s working capital requirements during the fiscal year ended March 31, 2018 were in-line with management’s expectations, which included higher collection of accounts receivable and the continued management of the timing of payments of accounts payable. However, we didn’t fully achieve our planned number of product shipments during the fiscal year ended March 31, 2018, resulting in an increase in finished goods inventory. The Company incurred a net loss of approximately $10.0 million and used cash in operating activities of approximately $8.6 million during the fiscal year ended March 31, 2018. The Company also had capital expenditures related to the consolidation of its facilities in Fiscal 2018 which contributed to the cash used in investing activities. As of March 31, 2018, the Company had cash, cash equivalents and restricted cash of approximately $19.4 million, and outstanding borrowings under its credit facility of approximately $8.5 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 Bridge Bank Credit Agreements 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 2018 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 2018 financial statements. 

Segment Reporting  The Company is considered to be a single reporting segment. The business activities of this reporting segment are the development, manufacture and sale of turbine generator sets and their related parts and service. Following is the geographic revenue information based on the primary operating location of the Company’s customers (in thousands):

 

The following table summarizes the Company’s revenue by product (in thousands):

 

Substantially all of the Company’s operating assets are in the United States.

Recent Accounting Pronouncements In February 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No 2018-02, Income Statement–Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income ("ASU 2018-02"). The ASU provides that the stranded tax effects from the Tax Act in accumulated other comprehensive loss may be reclassified to retained earnings. The Company adopted this ASU, which resulted in no adjustment to retained earnings.

On December 22, 2017, the SEC issued guidance under Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”) directing taxpayers to consider the impact of the U.S. legislation as “provisional” when it does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete its accounting for the change in tax law. In accordance with SAB 118, our estimated income tax is considered provisional and our analysis is expected to be finalized by the end of the 2018 calendar year.

In July 2017, the FASB issued a two-part ASU No. 2017-11, I. Accounting for Certain Financial Instruments With Down Round Features and II. Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests With a Scope Exception (“ASU 2017-11”). ASU 2017-11 amends guidance in FASB ASC 260, Earnings Per Share, FASB ASC 480, Distinguishing Liabilities from Equity, and FASB ASC 815, Derivatives and Hedging. The amendments in Part I of ASU 2017-11 change the classification analysis of certain equity-linked financial instruments (or embedded features) with down round features. The amendments in Part II of ASU 2017-11 re-characterize the indefinite deferral of certain provisions of Topic 480 that now are presented as pending content in the Codification, to a scope exception. Those amendments do not have an accounting effect. ASU 2017-11 is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted. The Company adopted ASU 2017-11 for the three months ended June 30, 2017, and retrospectively applied ASU 2017-11 as required. See Note 10—Fair Value Measurements for further discussion on changes as a result of the adoption of ASU 2017-11.

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. In September 2017, the FASB issued ASU 2017-13, Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842), which provides additional implementation guidance on the previously issued ASU 2016-02 Leases (Topic 842). ASU 2016-02 requires a lessee to recognize assets and liabilities on the balance sheet for leases with lease terms greater than 12 months. 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 May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). ASU 2014-09 supersedes a majority of existing revenue recognition guidance under US GAAP, and requires companies to recognize revenue when it transfers goods or services to a customer in an amount that reflects the consideration to which a company expects to be entitled. Companies may need to apply more judgment and estimation techniques or methods while recognizing revenue, which could result in additional disclosures to the financial statements. In addition, in March 2016, April 2016, May 2016 and December 2016 the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) (“ASU 2016-08”), ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing (“ASU 2016-10”), ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients (“ASU 2016-12”) and ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers (“ASU 2016-20”), respectively, to amend certain guidance in ASU 2014-09. Topic 606 allows for either a retrospective or cumulative effect transition method. ASU 2014-09 was originally effective for fiscal years beginning after December 15, 2016. In July 2015, the FASB approved a one-year deferral of ASU 2014-09 and all amendments to it, with a new effective date for fiscal years beginning after December 15, 2017 with early adoption permitted as of the original effective date.

The Company plans to adopt ASU 2014-09, as well as other clarifications and technical guidance issued by the FASB related to this new revenue standard, on April 1, 2018. We have developed our plan for implementing the new standard, which includes, but is not limited to, identifying contract populations and “in scope” customer contracts, identifying performance obligations in those customer contracts, and evaluating any impact of variable consideration. The Company has evaluated the transition methods and will likely apply the modified retrospective transition method, which would result in an adjustment to retained earnings for the cumulative effect, if any, of applying the standard to contracts that are not completed at the date of initial application. Under this method, the Company would not restate the prior financial statements presented, therefore the new standard requires the Company to provide additional disclosures of the amount by which each financial statement line item is affected in the current reporting period during the fiscal year ending March 31, 2019, as compared to the guidance that was in effect before the change, and an explanation of the reasons for significant changes, if any.

The impact that the new revenue recognition standard will have on the Company’s consolidated financial statements and disclosures has not yet been fully assessed.  However, the Company does not expect the provisions of the new standard to have a material effect on the timing or amount of revenue it recognizes. The Company’s assessment also includes determining the impact the new standard may have on the revenue reporting processes, including disclosures, ensuring internal controls will operate effectively with the new standard and performing gap analyses on collected data and determining the relative accounting positions where applicable.
