AMERICAN SUPERCONDUCTOR CORPORATION
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
1. Nature of the Business and Operations and Liquidity
Nature of the Business and Operations
American Superconductor Corporation (“AMSC” or the “Company”) was founded on April 9, 1987. The Company is a leading provider of megawatt-scale solutions that lower the cost of wind power and enhance the performance of the power grid. In the wind power market, the Company enables manufacturers to field wind turbines through its advanced engineering, support services and power electronics products. In the power grid market, the Company enables electric utilities and renewable energy project developers to connect, transmit and distribute power through its transmission planning services and power electronics and superconductor-based products. The Company’s wind and power grid products and services provide exceptional reliability, security, efficiency and affordability to its customers.
These unaudited condensed consolidated financial statements of the Company have been prepared on a going concern basis in accordance with United States generally accepted accounting principles (“GAAP”) and the Securities and Exchange Commission’s (“SEC”) instructions to Form 10-Q. The going concern basis of presentation assumes that the Company will continue operations and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to those instructions. The year-end condensed balance sheet data was derived from audited financial statements but does not include all disclosures required by GAAP. The unaudited condensed consolidated financial statements, in the opinion of management, reflect all adjustments (consisting of normal recurring adjustments) necessary for a fair statement of the results for the interim periods ended December 31, 2018 and 2017 and the financial position at December 31, 2018; however, these results are not necessarily indicative of results which may be expected for the full year. The interim condensed consolidated financial statements, and notes thereto, should be read in conjunction with the audited consolidated financial statements for the year ended March 31, 2018, and notes thereto, included in the Company’s annual report on Form 10-K for the year ended March 31, 2018 filed with the Securities and Exchange Commission on June 6, 2018.
Liquidity
The Company has experienced recurring operating losses and as of December 31, 2018, the Company had an accumulated deficit of $953.2 million. In addition, the Company has experienced recurring negative operating cash flows. At December 31, 2018, the Company had cash and cash equivalents of $80.0 million, with no outstanding debt other than ordinary trade payables. Cash provided by operations for the nine months ended December 31, 2018 was $47.8 million. The current period results include the net gain received from the first and second installments of the Sinovel settlement of $53.7 million in the nine month period ended December 31, 2018.
On July 3, 2018, the Company and its wholly-owned subsidiaries Suzhou AMSC Superconductor Co. Ltd. (“AMSC China”) and AMSC Austria GMBH (“AMSC Austria”) entered into a settlement agreement (the “Settlement Agreement”) with Sinovel Wind Group Co., Ltd. (“Sinovel”). The Settlement Agreement settles the litigation and arbitration proceedings between the Company and Sinovel. Under the terms of the Settlement Agreement, Sinovel agreed to pay AMSC China an aggregate cash amount in Renminbi (“RMB”) equivalent to $57.5 million, consisting of two installments. Sinovel paid the first installment of the RMB equivalent of $32.5 million on July 4, 2018, which was repatriated to the Company during the nine months ended December 31, 2018, and paid the second installment of the RMB equivalent of $25.0 million on December 27, 2018.
On February 1, 2018, ASC Devens LLC (the “Seller”), a wholly-owned subsidiary of the Company, entered into a Purchase and Sale Agreement (the “PSA”) with 64 Jackson, LLC (the “Purchaser”) and Stewart Title Guaranty Company (“Escrow Agent”), to effectuate the sale of certain real property located at 64 Jackson Road, Devens, Massachusetts, including the building that had served as the Company’s headquarters (collectively, the “Property”), in exchange for total consideration of $23.0 million, composed of (i) cash consideration of $17.0 million, and (ii) a $6.0 million subordinated secured commercial promissory note payable to the Company (the “Seller Note”). Subsequently, the Seller, the Purchaser and Jackson 64 MGI, LLC (“Assignee”) entered into an Assignment of Purchase and Sale Agreement (the “Assignment Agreement”), pursuant to which the Purchaser assigned all of its rights and interests in the PSA to the Assignee and the Assignee agreed to assume all of the Purchaser’s obligations and liabilities under the PSA. The transaction closed on March 28, 2018, at which time the Company received, from the Assignee, cash consideration, net of certain agreed upon closing costs, of $16.9 million, and the Seller Note at an interest rate of 1.96%. The Seller Note is secured by a subordinated second mortgage on the Property and a subordinated second assignment of leases and rents.
7

In December 2015, the Company entered into a set of strategic agreements valued at approximately $210.0 million with Inox Wind Ltd. (“Inox” or “Inox Wind”), which includes a multi-year supply contract pursuant to which the Company will supply electrical control systems to Inox and a license agreement allowing Inox to manufacture a limited number of electrical control systems. After Inox purchases the specified number of electrical control systems required under the terms of the supply contract, Inox agreed that the Company will continue as Inox’s preferred supplier and Inox will be required to purchase from the Company a majority of its electrical control systems requirements for an additional three-year period.
The Company believes that based on the information presented above and its quarterly management assessment, it has sufficient liquidity to fund its operations and capital expenditures for the next twelve months following the issuance of the financial statements for the three and nine months ended December 31, 2018. The Company’s liquidity is highly dependent on its ability to increase revenues, including its ability to collect revenues under its agreements with Inox, its ability to control its operating costs, and its ability to raise additional capital, if necessary. There can be no assurance that the Company will be able to continue to raise additional capital, on favorable terms or at all, from other sources or execute on any other means of improving liquidity described above.
2. Revenue Recognition
On April 1, 2018, the Company adopted Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers, and all the related amendments and applied it to all contracts that were not completed as of April 1, 2018 using the modified retrospective method. The Company recognized the cumulative effect of initially applying the new revenue standard as an adjustment of less than $0.1 million to the opening balance of accumulated deficit. Prior period amounts have not been restated and continue to be reported under the accounting standards in effect for those periods.
The adoption of this guidance has led to recognizing certain revenue transactions sooner than in the past on certain contracts, as the Company will need to estimate the revenue it will be entitled to upon contract completion, and later on other contracts, such as Consulting and Statement of Work transactions, due to the lack of an enforceable right to payment for performance obligations satisfied over time, specifically in the technology product line. The Company does not expect a material impact to its consolidated statements of operations on an ongoing basis from the adoption of the new standard.
In addition, the FASB issued Accounting Standards Update (“ASU”) 2017-05, Other Income - Gains and Losses from the Derecognition of Non-financial Assets (Subtopic 610-20), in February 2017, to amend ASC 610-20, Other Income - Gains and Losses from the Derecognition of Non-financial Assets (issued at the same time as ASC 606), which provides a model for the measurement and recognition of gains and losses on the sale of non-financial assets, such as property and equipment, including real estate. As a result of adopting ASU 2017-05 on April 1, 2018, the Company recognized an adjustment to the opening balance of accumulated deficit for the deferred gain from the March 28, 2018 sale of the Company's former headquarters in Devens, Massachusetts in the amount of $0.1 million.
The cumulative effect to the Company’s consolidated April 1, 2018 balance sheet from the adoption of the new revenue standard and the sale of nonfinancial assets was as follows (in thousands):

| March 31, 2018 |  | Opening Adjustment |  | April 1, 2018
Assets: |  |  |  |  |
Accounts Receivable | $ | 7,365 |  |  | $ | (678 | ) |  | $ | 6,687 |
Inventory | 19,780 |  |  | (1,599 | ) |  | 18,181 |
Prepaid expenses and other current assets | 2,947 |  |  | 2,277 |  |  | 5,224 |
Notes receivable, long term portion | 2,559 |  |  | 105 |  |  | 2,664 |
Liabilities and Stockholders' Equity: |  |  |  |  |
Accounts payable and accrued expenses | $ | (12,625 | ) |  | $ | (2,729 | ) |  | $ | (15,354 | )
Deferred revenue | (13,483 | ) |  | 2,657 |  |  | (10,826 | )
Accumulated deficit | $ | (988,333 | ) |  | $ | (33 | ) |  | $ | (988,366 | )

8

Included in the opening adjustment are reclassifications for accounts receivable, deferred program costs and deferred revenue for previous balances related to agreements that no longer meet the definition of a customer contract under ASC 606. The impact of adoption on the Company’s opening balances and for the three and nine months ended December 31, 2018, in all financial statement line items impacted by ASC 606 was immaterial from the amount that would have been reported under the previous guidance.
The Company’s revenues in its Grid segment are derived primarily through enabling the transmission and distribution of power, providing planning services that allow it to identify power grid needs and risks, and developing ship protection systems for the U.S. Navy. The Company’s revenues in its Wind segment are derived primarily through supplying advanced power electronics and control systems, licensing our highly engineered wind turbine designs, and providing extensive customer support services to wind turbine manufacturers. The Company records revenue based on a five-step model in accordance with ASC 606. For its customer contracts, the Company identifies the performance obligations, determines the transaction price, allocates the contract transaction price to the performance obligations, and recognizes the revenue when (or as) control of goods or services is transferred to the customer. As of December 31, 2018, 87% of revenue was recognized at the point in time when control transferred to the customer, with the remainder being recognized over time.
In the Company's equipment and system product line, each contract with a customer summarizes each product sold to a customer, which typically represent distinct performance obligations. A contract's transaction price is allocated to each distinct performance obligation using the respective standalone selling price which is determined primarily using the cost plus expected margin approach and recognized as revenue when, or as, the performance obligation is satisfied. The majority of the Company’s product sales transfer control to the customer in line with the contracted delivery terms and revenue is recorded at the point in time when products are transferred to the freight forwarder, as the Company has determined that this is the point in time that control transfers to the customer.
In the Company's service and technology development product line, there are several different types of transactions but each of them begins with a contract with a customer that summarizes each product sold to a customer, which typically represents distinct performance obligations. The technology development transactions are primarily for activities that have no alternative use and for which a profit can be expected throughout the life of the contract. In these cases, the revenue is recognized over time, but in the instances where the profit cannot be assured throughout the entire contract then the revenue is recognized at a point in time. Each contract's transaction price is allocated to each distinct performance obligation using the respective standalone selling price which is determined primarily using the cost plus expected margin approach. The ongoing service transactions are for service contracts that provide benefit to the customer simultaneously as the Company performs its obligations, and therefore this revenue is recognized ratably over time throughout the effective period of these contracts. The transaction prices on these contracts are allocated based on an adjusted market approach which is re-assessed annually for reasonableness. The field service transactions include contracts for delivery of goods and completion of services made at the customer's requests, which are not deemed satisfied until the work has been completed and/or the requested goods have been delivered, so all of this revenue is recognized at the point in time when the control changes, and at allocated prices based on the adjusted market approach driven by standard price lists. The royalty transactions are related to certain contract terms on transactions in the Company's equipment and systems product line based on activity as specified in the contracts. The transaction prices of these agreements are calculated based on an adjusted market approach as specified in the contract. The Company reports royalty revenue for usage-based royalties when the sales have occurred. In circumstances when collectability is not assured and a contract does not exist under ASC 606, revenue is deferred until a non-refundable payment has been received for substantially all the amount that is due and there are no further remaining performance obligations.
The Company's service contracts can include a purchase order from a customer for specific goods in which each item is a distinct performance obligation satisfied at a point in time at which control of the goods is transferred to the customer which occurs based on the contracted delivery terms or when the requested service work has been completed. The transaction price for these goods is allocated based on the adjusted market approach considering similar transactions under similar circumstances. Service contracts are also derived from ongoing maintenance contracts and extended service-type warranty contracts. In these transactions, the Company is contracted to provide an ongoing service over a specified period of time. As the customer is consuming the benefits as the service is being provided the revenue is recognized over time ratably.
The Company’s policy is to not accept volume discounts, product returns, or rebates and allowances within its contracts. In the event a contract was approved with any of these terms, it would be evaluated for variable consideration, estimated and recorded as a reduction of revenue in the same period the related product revenue was recorded.
The Company provides assurance-type warranties on all product sales for a term of typically one to two years, and extended service-type warranties at the customers’ option for an additional term ranging up to four additional years. The Company accrues for the estimated warranty costs for assurance warranties at the time of sale based on historical warranty experience plus any
9

known or expected changes in warranty exposure. For all extended service-type warranties, the Company recognizes the revenue ratably over time during the effective period of the services.
The Company records revenue net of sales tax, value added tax, excise tax and other taxes collected concurrent with revenue-producing activities. The Company has elected to recognize the cost for freight and shipping when control over the products sold passes to customers and revenue is recognized. The Company has elected to recognize incremental costs of obtaining a contract as expense when incurred except in contracts where the amortization period would exceed twelve months; in such cases the long term amount will be assessed for materiality. The Company has elected to not adjust the promised amount of consideration for the effects of a significant financing component if the period of financing is twelve months or less.
The Company’s contracts with customers do not typically include extended payment terms and may include milestone billing over the life of the contract. Payment terms vary by contract type and type of customer and generally range from 30 to 60 days from delivery.
The following tables disaggregate the Company’s revenue by product line and by shipment destination:

As of December 31, 2018 and March 31, 2018, the Company’s contract assets and liabilities primarily relate to the timing differences between cash received from a customer in connection with contractual rights to invoicing and the timing of revenue recognition following completion of performance obligations. The Company's accounts receivable balance is made up entirely of customer contract related balances. Changes in the Company’s contract assets, which are included in “Unbilled AR” and “Deferred program costs” (see Note 7, “Accounts Receivable” and Note 8, “Inventory” for a reconciliation to the condensed consolidated balance sheet) and contract liabilities, which are included in the current portion and long term portion of “deferred revenue” in the Company’s condensed consolidated balance sheets, are as follows:

| Unbilled AR |  | Deferred Program Costs |  | Contract Liabilities
Beginning balance as of March 31, 2018 | $ | 3,016 |  |  | $ | 2,567 |  |  | $ | 21,937 |

The Company’s remaining performance obligations represent the unrecognized revenue value of the Company’s contractual commitments. The Company’s performance obligations may vary significantly each reporting period based on the timing of major new contractual commitments. As of December 31, 2018, the Company had outstanding performance obligations on existing contracts under ASC 606 to be recognized in the next twelve months of approximately $36.8 million. There are also approximately $12.9 million of outstanding performance obligations to be recognized over a period of thirteen to sixty months. The remaining performance obligations are subject to customer actions and therefore the timing of revenue recognition cannot be reasonably estimated. The twelve month performance obligations include anticipated shipments to Inox based on the twelve month rolling forecast provided by Inox on the multi-year supply contract. The quantities specified in any forecast provided by Inox related to the multi-year supply contract are firm and irrevocable for the first three months of a twelve month rolling forecast. The timing of the performance obligations beyond the Inox twelve month provided forecast are not determinable and therefore are not included in the total remaining performance obligations.
The following table sets forth customers who represented 10% or more of the Company’s total revenues for the three and nine months ended December 31, 2018 and 2017:

| Reportable |  | Three Months Ended December 31, |  | Nine Months Ended December 31,
| Segment |  | 2018 |  | 2017 |  | 2018 |  | 2017

3. Stock-Based Compensation
The Company accounts for its stock-based compensation at fair value. The following table summarizes stock-based compensation expense by financial statement line item for the three and nine months ended December 31, 2018 and 2017 (in thousands):

| Three months ended December 31, |  | Nine months ended December 31,
| 2018 |  | 2017 |  | 2018 |  | 2017
Cost of revenues | $ | 42 |  |  | $ | 39 |  |  | $ | 132 |  |  | $ | 98 |
Research and development | 168 |  |  | 184 |  |  | 289 |  |  | 294 |
Selling, general and administrative | 582 |  |  | 660 |  |  | 1,981 |  |  | 1,723 |
Total | $ | 792 |  |  | $ | 883 |  |  | $ | 2,402 |  |  | $ | 2,115 |

The Company issued 47,075 shares of immediately vested common stock and 463,000 shares of restricted stock awards during the nine months ended December 31, 2018, and issued 37,140 shares of immediately vested common stock and 800,500 shares of restricted stock awards during the nine months ended December 31, 2017. These restricted stock awards generally vest over 2-3 years. Awards for restricted stock include both time-based and performance-based awards. For options and restricted stock awards that vest upon the passage of time, expense is being recorded over the vesting period. Performance-based awards are expensed over the requisite service period based on probability of achievement. In addition, the Company issued 16,667 restricted stock units under the 2007 Stock Incentive Plan during the nine months ended December 31, 2017, each of which represents the right to receive one share of common stock in connection with a severance agreement entered into with one of the Company's former executive officers. These restricted stock units vested and were settled in shares of common stock on the eighth day after receipt of an irrevocable release.
The estimated fair value of the Company’s stock-based awards, less expected annual forfeitures, is amortized over the awards’ service period. The total unrecognized compensation cost for unvested outstanding stock options was $0.1 million at December 31, 2018. This expense will be recognized over a weighted average expense period of approximately 0.3 years. The total unrecognized compensation cost for unvested outstanding restricted stock was $3.3 million at December 31, 2018. This expense will be recognized over a weighted-average expense period of approximately 1.8 years.
The Company did not grant any stock options during the three and nine months ended December 31, 2018 or 2017.

4. Computation of Net Income (Loss) per Common Share
Basic net income (loss) per share (“EPS”) is computed by dividing net income (loss) by the weighted-average number of common shares outstanding for the period. Where applicable, diluted EPS is computed by dividing the net income (loss) by the weighted-average number of common shares and dilutive common equivalent shares outstanding during the period, calculated using the treasury stock method. Common equivalent shares include the effect of restricted stock, exercise of stock options and warrants and contingently issuable shares. Stock options that are out-of-the-money with exercise prices greater than the average market price of the underlying Common Shares and equity awards with performance shares where the contingency was not met are excluded from the computation of diluted EPS as the effect of their inclusion would be anti-dilutive. For the three months ended December 31, 2018, 0.5 million shares were not included in the calculation of diluted EPS as they were considered anti-dilutive, of which 0.3 million relate to outstanding stock options, and 0.2 million relate to outstanding equity awards. For the nine months ended December 31, 2018, 1.1 million shares were not included in the calculation of diluted EPS as they were considered anti-dilutive, of which 0.3 million relate to outstanding stock options, 0.6 million relate to outstanding warrants and 0.2 million relate to outstanding equity awards. For the three and nine months ended December 31, 2017, 1.2 million shares were not included in the calculation of diluted EPS as they were considered anti-dilutive, of which 0.3 million relate to outstanding stock options, and 0.9 million relate to outstanding warrants.
The following table reconciles the numerators and denominators of the earnings per share calculation for the three and nine months ended December 31, 2018 and 2017 (in thousands, except per share data):

5. Acquisition and Related Goodwill
Acquisition of Infinia Technology Corporation
On September 25, 2017, the Company acquired Infinia Technology Corporation ("ITC") for approximately $3.8 million (the "Acquisition"). Located in Richmond, Washington, ITC is a technology firm founded in 2009 specializing in the design, development and commercialization of cryo-coolers for a wide range of applications. This technology supports the Company's efforts with the U.S. Navy and Ship Protection Systems (“SPS”) products.
The results of ITC's operations, which were not significant from the date of acquisition through December 31, 2018, are included in the Company’s consolidated results from the date of Acquisition of September 25, 2017, through December 31, 2018. Assuming the Acquisition had occurred on April 1, 2017, the impact on the consolidated results of the Company would not have been significant.
Goodwill
At the time of the Acquisition, the Company allocated the purchase price to the assets acquired and liabilities assumed at their estimated fair values as of the date of Acquisition. The excess of the purchase price paid by the Company over the estimated fair value of net assets acquired of $1.7 million has been recorded as goodwill in the Company's Grid segment. Goodwill represents the value associated with the acquired workforce and synergies related to the merger of the two companies.
The Company did not identify any triggering events in the nine months ended December 31, 2018, that would require interim impairment testing of goodwill.

6. Fair Value Measurements
A valuation hierarchy for disclosure of the inputs to valuation used to measure fair value has been established. This hierarchy prioritizes the inputs into three broad levels as follows:

| Level 1 | - | Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
| Level 2 | - | Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs).
| Level 3 | - | Unobservable inputs that reflect the Company’s assumptions that market participants would use in pricing the asset or liability. The Company develops these inputs based on the best information available, including its own data.

The Company provides a gross presentation of activity within Level 3 measurement roll-forward and details of transfers in and out of Level 1 and 2 measurements. A change in the hierarchy of an investment from its current level is reflected in the period during which the pricing methodology of such investment changes. Disclosure of the transfer of securities from Level 1 to Level 2 or Level 3 is made in the event that the related security is significant to total cash and investments. The Company did not have any transfers of assets and liabilities from Level 1, Level 2 or Level 3 of the fair value measurement hierarchy during the nine months ended December 31, 2018.
A financial asset’s or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.
The following table provides the assets and liabilities carried at fair value on a recurring basis, measured as of December 31, 2018 and March 31, 2018 (in thousands):

| Total Carrying Value |  | Quoted Prices in Active Markets (Level 1) |  | Significant Other Observable Inputs (Level 2) |  | Significant Unobservable Inputs (Level 3)

Valuation Techniques
Cash Equivalents
Cash equivalents consist of highly liquid instruments with maturities of three months or less that are regarded as high quality, low risk investments and are measured using such inputs as quoted prices, and are classified within Level 1 of the valuation hierarchy. Cash equivalents consist principally of certificates of deposits and money market accounts.
Warrants
Warrants were issued in conjunction with a Securities Purchase Agreement (the “Purchase Agreement”) with Capital Ventures International (“CVI”), an equity offering to Hudson Bay Capital in November 2014, and a Loan and Security Agreement with Hercules Technology Growth Capital, Inc. (“Hercules”). The warrants issued to CVI expired on October 4, 2017. See Note 13 “Warrants and Derivative Liabilities,” for additional information. Outstanding warrants are subject to revaluation at each balance sheet date, and any change in fair value will be recorded as a change in fair value in derivatives and warrants until the earlier of their exercise or expiration.
The Company relies on various assumptions in a lattice model to determine the fair value of warrants. The Company has valued the warrants within Level 3 of the valuation hierarchy. See Note 13, “Warrants and Derivative Liabilities,” for a discussion of the warrants and the valuation assumptions used.
Contingent Consideration
Contingent consideration relates to a make whole payment provision set forth in the stock purchase agreement ("SPA") for the acquisition of ITC that required the Company to guarantee the purchase price of the acquisition had the aggregate proceeds of the resale of AMSC shares sold by selling stockholders during the first 90 days after the effectiveness of the resale registration statement been less than the agreed upon purchase price for such AMSC shares (per the terms of the SPA) sold during such 90 day period. See Note 13, "Warrants and Derivative Liabilities" and Note 5, “Acquisition and Related Goodwill” for further discussion. The Company relied on a Black Scholes option pricing method to determine the fair value of the contingent consideration on the date of acquisition. All of the stock related to this liability was sold as of December 5, 2017 and the amount of the make whole payment provided for in the SPA was calculated to be $0.7 million, and subsequently paid on January 5, 2018.
7. Accounts Receivable

Deferred program costs | 1,296 |  |  | 2,567 |
Net inventory | $ | 14,006 |  |  | $ | 19,780 |

The Company recorded inventory write-downs of $0.2 million and $0.1 million for the three months ended December 31, 2018 and 2017, respectively. The Company recorded inventory write-downs of $0.7 million and $0.4 million for the nine months ended December 31, 2018 and 2017, respectively. These write-downs were based on the Company's evaluation of its inventory on hand for excess quantities and obsolescence.
Deferred program costs as of December 31, 2018 and March 31, 2018 primarily represent costs incurred on programs where the Company needs to complete performance obligations before the related revenue and costs will be recognized.
9. Note Receivable
The Company entered into the PSA dated February 1, 2018, for the sale of the Devens facility (including land, building and building improvements) located at 64 Jackson Road, Devens, Massachusetts to Jackson Road, LLC, a limited liability company (subsequently assigned to Jackson 64 MGI, LLC) in the amount of $23.0 million. The terms for payment included a $1.0 million security deposit, and a note receivable for $6.0 million payable to the Company with the remaining cash net of certain adjustments for closing costs at the date of settlement. The note receivable is due in two $3.0 million installments plus accrued interest at a rate of 1.96% on March 31, 2019 and March 31, 2020. The note is subordinate to East Boston Savings Bank's mortgage on the Devens property.
The note receivable was discounted to its present value of $5.7 million utilizing a discount rate of 6%, which was based on management’s assessment of what an appropriate loan at current market rates would be. The $0.3 million discount was recorded as an offset to the long term portion of the note receivable, and is being amortized to interest income over the term of the note. In addition, the resulting gain of $0.1 million from the sale of the Devens property which was deferred previously was recorded as a component of the cumulative effect of an accounting change upon the adoption of ASU 2017-05 which was issued as a part of ASU 2014-09. This gain was recorded as an offset to the opening accumulated deficit.
Note receivable as of December 31, 2018 and March 31, 2018 consisted of the following (in thousands):

12. Income Taxes
T he Company recorded an income tax expense of $1.6 million and $4.5 million in the three and nine months ended December 31, 2018, respectively. The Company recorded income tax expense of $0.6 million and $0.5 million in the three and nine months ended December 31, 2017, respectively.
On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Act”) was signed into law. ASC Topic 740 requires deferred tax assets and liabilities to be measured using the enacted rate for the period in which they are expected to reverse. Accordingly,
16

the new 21% U.S. Federal corporate tax rate was used to measure the U.S. deferred tax assets and liabilities that will reverse in future periods. The Company's deferred tax attributes are generally subject to a full valuation allowance in the U.S. and thus, this adjustment to the attributes did not impact the tax provision. In addition, the new legislation includes a one-time transition tax in which all foreign earnings are deemed to be repatriated to the U.S. and taxable at specified rates included within the Act. The Company reviewed the accumulated foreign earnings aggregated across all non U.S. subsidiaries, net of foreign deficits. The Company believes it is in an aggregate net foreign deficit position for U.S. tax purposes and therefore not liable for the transition tax. The SEC staff issued Staff Accounting Bulletin No. 118, which provides guidance for companies that have not completed their accounting for the income tax effects of the Act in the period of enactment, allowing for a measurement period of up to one year after the enactment date to finalize the recording of the related tax impacts. As of December 31, 2018, the Company completed its tax accounting for the income tax effects of the Act and made no updates to its initial estimates. The Act had no significant financial impact for the fiscal year ended March 31, 2018.
Accounting for income taxes requires a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if, based on the technical merits, it is more likely than not the position will be sustained upon audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. The Company re-evaluates these uncertain tax positions on a quarterly basis. The evaluation is based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit and new audit activity. Any changes in these factors could result in the recognition of a tax benefit or an additional charge to the tax provision. The Company did not identify any uncertain tax positions in the nine months ended December 31, 2018 and did no t have any gross unrecognized tax benefits as of March 31, 2018.
13. Warrants and Derivative Liabilities
The Company accounts for its warrants and contingent consideration as liabilities due to certain adjustment provisions within the instruments, which require that they be recorded at fair value. The warrants are subject to revaluation at each balance sheet date and any change in fair value is recorded as a change in fair value of warrants until the earlier of its expiration or its exercise at which time the warrant liability will be reclassified to equity. The Company calculated the fair value of the warrants utilizing an integrated lattice model. See Note 6, "Fair Value Measurements", for further discussion.

The Company issued Hercules warrants to purchase 13,927 shares of common stock (the “First Warrant”) and 25,641 shares of common stock (the “Second Warrant”) in conjunction with prior term loans that have been repaid in full. On December 19, 2014, the Company entered into a second amendment to the Loan and Security Agreement with Hercules (the "Hercules Second Amendment"). In conjunction with the Hercules Second Amendment, the Company issued Hercules a warrant to purchase 58,823 shares of the Company’s common stock (the "Hercules Warrant") which replaced the First Warrant and the Second Warrant. The Hercules Warrant is exercisable at any time after its issuance at an exercise price of $7.85 per share, subject to certain price-based and other anti-dilution adjustments, including the equity offering in May 2017, the acquisition of ITC with common stock in September 2017 and sales of common stock under the ATM entered into in January 2017, and expires on June 30, 2020. This warrant had a fair value of $0.3 million as of December 31, 2018 and $0.1 million as of March 31, 2018.
November 2014 Warrant
On November 13, 2014, the Company completed an offering of 909,090 units of the Company’s common stock with Hudson Bay Capital. Each unit consisted of one share of the Company’s common stock and 0.9 of a warrant to purchase one share of common stock, or a warrant to purchase in the aggregate 818,181 shares (the “November 2014 Warrant”). The November 2014 Warrant is exercisable at any time, at an exercise price equal to $7.81 per share, subject to certain price-based and other anti-dilution adjustments including those noted above, and expires on November 13, 2019.

Following is a summary of the key assumptions used to calculate the fair value of the November 2014 Warrant:

Fiscal Year 18 | December 31, 2018 |  | September 30, 2018 |  | June 30, 2018
Risk-free interest rate | 2.61% |  | 2.62% |  | 2.40%
Expected annual dividend yield | — |  | — |  | —
Expected volatility | 70.29% |  | 63.66% |  | 67.40%
Term (years) | 0.87 |  | 1.12 |  | 1.37
Fair value | $3.6 million |  | $1.3 million |  | $1.6 million

Fiscal Year 17 | March 31, 2018 |  | December 31, 2017 |  | September 30, 2017 |  | June 30, 2017 |  | March 31, 2017
Risk-free interest rate | 2.20% |  | 1.87% |  | 1.49% |  | 1.44% |  | 1.41%
Expected annual dividend yield | — |  | — |  | — |  | — |  | —
Expected volatility | 65.86% |  | 65.86% |  | 65.64% |  | 67.21% |  | 66.53%
Term (years) | 1.62 |  | 1.87 |  | 2.12 |  | 2.37 |  | 2.62
Fair value | $1.1 million |  | $0.4 million |  | $0.8 million |  | $0.9 million |  | $1.8 million

The Company recorded net losses of $2.3 million and $2.5 million resulting from the increase in the fair value of the November 2014 Warrant during the three and nine months ended December 31, 2018, respectively. The Company recorded net gains of $0.4 million and $1.4 million, resulting from the decrease in the fair value of the November 2014 Warrant during the three and nine months ended December 31, 2017, respectively.
14. Stockholders’ Equity
Equity Offerings
On May 5, 2017, the Company entered into an underwriting agreement with Oppenheimer & Co. Inc., as representative of several underwriters named therein, relating to the issuance and sale (the "Offering") of 4.0 million shares of the Company's common stock at a public offering price of $4.00 per share. The net proceeds to the Company from the Offering were approximately $14.7 million, after deducting underwriting discounts and commissions and offering expenses payable by the Company. The Offering closed on May 10, 2017. In addition, the Company granted the underwriters a 30-day option (the “Option”) to purchase up to an additional 600,000 shares of common stock at the same public offering price. On May 24, 2017, the underwriters notified the Company that they had exercised their Option in full. The net proceeds to the Company from the Option were approximately $2.3 million, after deducting underwriting discounts and commissions and offering expenses payable by the Company. The total net proceeds to the Company from the Offering and the Option were approximately $17.0 million, after deducting underwriting discounts and commissions and offering expenses payable by the Company. The Option closed on May 26, 2017. In conjunction with the equity offering, the Company terminated a previous ATM with FBR Capital Markets & Co. where the Company could, at its discretion, sell up to $10.0 million of the Company's common stock.
15. Commitments and Contingencies
Legal Contingencies
From time to time, the Company is involved in legal and administrative proceedings and claims of various types. The Company records a liability in its consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. The Company reviews these estimates each accounting period as additional information is known and adjusts the loss provision when appropriate. If a matter is both probable to result in a liability and the amounts of loss can be reasonably estimated, the Company estimates and discloses the possible loss or range of loss to the extent necessary to make the consolidated financial statements not misleading. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in its consolidated financial statements.
18

Other
The Company enters into long-term construction contracts with customers that require the Company to obtain performance bonds. The Company is required to deposit an amount equivalent to some or all the face amount of the performance bonds into an escrow account until the termination of the bond. When the performance conditions are met, amounts deposited as collateral for the performance bonds are returned to the Company. In addition, the Company has various contractual arrangements in which minimum quantities of goods or services have been committed to be purchased on an annual basis.
As of December 31, 2018, the Company had $0.2 million of restricted cash included in long-term assets. These amounts included in restricted cash primarily represent deposits to secure letters of credit for various supply contracts. These deposits are held in interest bearing accounts.
16. Restructuring
The Company accounts for charges resulting from operational restructuring actions in accordance with ASC Topic 420, Exit or Disposal Cost Obligations (“ASC 420”) and ASC Topic 712, Compensation—Nonretirement Postemployment Benefits (“ASC 712”). In accounting for these obligations, the Company is required to make assumptions related to the amounts of employee severance, benefits, and related costs and the time period over which leased facilities will remain vacant, sublease terms, sublease rates and discount rates. Estimates and assumptions are based on the best information available at the time the obligation arises. These estimates are reviewed and revised as facts and circumstances dictate; changes in these estimates could have a material effect on the amount accrued on the consolidated balance sheet.
The $0.4 million charged to operations in the nine months ended December 31, 2018 is related to exit costs incurred for the move of the Company's corporate office.
On April 3, 2017, the Board of Directors approved a plan to reduce the Company’s global workforce by approximately 8%, effective April 4, 2017. The purpose of the workforce reduction was to reduce operating expenses to better align with the Company’s current revenues. Included in the $1.3 million severance pay, charged to operations in the nine months ended December 31, 2017, is $0.5 million of severance pay for one of the Company's former executive officers pursuant to the terms of a severance agreement dated June 30, 2017. Under the terms of the severance agreement, the Company's former executive officer was entitled to 18 months of his base salary, which was paid in cash by December 31, 2018.
The following table presents restructuring charges and cash payments for the nine months ended December 31, 2018 and 2017 (in thousands):

| Severance pay |  | Facility exit and |  |
| and benefits |  | Relocation costs |  | Total
Accrued restructuring balance at April 1, 2018 | $ | 262 |  |  | $ | 173 |  |  | $ | 435 |
Charges to operations | — |  |  | 450 |  |  | 450 |

17. Business Segments
The Company reports its financial results in two reportable business segments: Wind and Grid.
Through the Company’s Windtec Solutions, the Wind business segment enables manufacturers to field wind turbines with exceptional power output, reliability and affordability. The Company supplies advanced power electronics and control systems, licenses its highly engineered wind turbine designs, and provides extensive customer support services to wind turbine manufacturers. The Company’s design portfolio includes a broad range of drive trains and power ratings of 2 megawatts ("MWs") and higher. The Company provides a broad range of power electronics and software-based control systems that are highly integrated and designed for optimized performance, efficiency, and grid compatibility.
Through the Company’s Gridtec Solutions, the Grid business segment enables electric utilities and renewable energy project developers to connect, transmit and distribute power with exceptional efficiency, reliability and affordability. The sales process is enabled by transmission planning services that allow it to identify power grid congestion, poor power quality and other risks, which helps the Company determine how its solutions can improve network performance. These services often lead to sales of grid interconnection solutions for wind farms and solar power plants, power quality systems, and transmission and distribution cable systems. The Company also sells ship protection products to the U.S. Navy through its Grid business segment.
The operating results for the two business segments are as follows (in thousands):

| Three months ended December 31, |  | Nine months ended December 31,
| 2018 |  | 2017 |  | 2018 |  | 2017
Revenues: |  |  |  |  |  |  |
Wind | $ | 7,308 |  |  | $ | 2,633 |  |  | $ | 18,293 |  |  | $ | 10,465 |
Grid | 6,826 |  |  | 12,300 |  |  | 23,325 |  |  | 24,439 |
Total | $ | 14,134 |  |  | $ | 14,933 |  |  | $ | 41,618 |  |  | $ | 34,904 |

| Three months ended December 31, |  | Nine months ended December 31,
| 2018 |  | 2017 |  | 2018 |  | 2017
Operating profit/(loss): |  |  |  |  |  |  |
Wind | $ | 24,269 |  |  | $ | (1,684 | ) |  | $ | 51,419 |  |  | $ | (7,557 | )
Grid | (2,665 | ) |  | (1,011 | ) |  | (8,202 | ) |  | (15,279 | )
Unallocated corporate expenses | (839 | ) |  | (1,156 | ) |  | (2,851 | ) |  | (3,514 | )
Total | $ | 20,765 |  |  | $ | (3,851 | ) |  | $ | 40,366 |  |  | $ | (26,350 | )

The accounting policies of the business segments are the same as those for the consolidated Company. The Company’s business segments have been determined in accordance with the Company’s internal management structure, which is organized based on operating activities. The Company evaluates performance based upon several factors, of which the primary financial measures are segment revenues and segment operating profit (loss). The disaggregated financial results of the segments reflect allocation of certain functional expense categories consistent with the basis and manner in which Company management internally disaggregates financial information for the purpose of assisting in making internal operating decisions. In addition, certain corporate expenses which the Company does not believe are specifically attributable or allocable to either of the two business segments have been excluded from the segment operating profit (loss).
Unallocated corporate expenses primarily consist of stock-based compensation expense of $0.8 million and $0.9 million in the three months ended December 31, 2018 and 2017, respectively, and restructuring charges of less than $0.1 million in both periods. Unallocated corporate expenses primarily consist of stock-based compensation expense of $2.4 million and $2.1 million and restructuring charges of $0.5 million and $1.3 million, included in the nine months ended December 31, 2018 and 2017, respectively, as well as losses for the change in fair value of the contingent consideration of $0.3 million and $0.1 million in the three and nine months ended December 31, 2017, respectively.
Total assets for the two business segments as of December 31, 2018 and March 31, 2018 are as follows (in thousands):
20

| December 31, 2018 |  | March 31, 2018
Wind | $ | 8,204 |  |  | $ | 16,790 |
Grid | 38,214 |  |  | 37,012 |
Corporate assets | 82,086 |  |  | 34,373 |
Total | $ | 128,504 |  |  | $ | 88,175 |

18. Recent Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board (“FASB”) and the International Accounting Standards Board ("IASB") issued, ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The guidance substantially converges final standards on revenue recognition between the FASB and IASB providing a framework on addressing revenue recognition issues and, upon its effective date, replaces almost all existing revenue recognition guidance, including industry-specific guidance, in current U.S. generally accepted accounting principles. The FASB has subsequently issued multiple amendments to ASU 2014-09 which are all effective for annual reporting periods beginning after December 15, 2017.
As of April 1, 2018, the Company has adopted ASU 2014-09 and its amendments, reported the impact in its consolidated financial statements, and implemented changes to its business processes, systems and controls to support revenue recognition and the related disclosures under this ASU. The Company’s assessment included a detailed review of representative contracts from each of the Company’s revenue streams and a comparison of its historical accounting policies and practices to the new standard. The Company adopted the new standards retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the modified retrospective transition method) to all existing contracts that have remaining obligations as of April 1, 2018. Accordingly, the Company has elected to retroactively adjust only those contracts that do not meet the definition of a complete contract at the date of the initial application. This guidance will lead to recognizing certain revenue transactions sooner than in the past on certain contracts, as the Company will need to estimate the revenue it will be entitled to upon contract completion, and later on other contracts, such as Consulting and Statement of Work transactions, due to the lack of an enforceable right to payment for performance obligations satisfied over time. There are no changes in the accounting for its largest revenue stream which includes Inox Wind as its primary customer. Across other revenue streams such as D-VAR® Equipment and D-VAR® t urnkey projects, the timing of revenue recognition will be affected for multiple types of contracts, primarily multiple performance obligation contracts in its Grid business unit, but those differences did not have a material impact on its consolidated financial statements. The adjustment to opening accumulated deficit was not significant in the period commencing on April 1, 2018. Additionally, the adoption of this new standard is not expected to have any tax impact on the consolidated financial statements. As part of this analysis, the Company evaluated its information technology capabilities and systems, and did not incur significant information technology costs to modify systems currently in place.
In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in ASU 2016-01 will enhance the reporting model for financial instruments to provide users of financial statements with more decision-useful information. This ASU is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those fiscal years. The Company adopted ASU 2016-01 effective April 1, 2018 and noted no significant impact to its consolidated financial statements.
In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The guidance in this ASU supersedes the leasing guidance in Topic 840, Leases. Under the new guidance, lessees are required to recognize lease assets and lease liabilities on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. This ASU and its amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.

• | In July 2018, the FASB issued ASU 2018-10, Codification improvements to Topic 842, Leases. The amendments in ASU 2018-10 provide more clarification in regards to the application and requirements of ASU 2016-02.

• | In July 2018, the FASB issued ASU 2018-11, Topic 842, Leases - Targeted improvements. The amendments in ASU 2018-11 provide for the option to adopt the standard prospectively and recognize a cumulative-effect adjustment to the opening balance of retained earnings as well as offer a new practical expedient that will allow the Company to elect, by class of underlying asset, to not separate non-lease and lease components in certain circumstances and instead to account for those components as a single item.

21

The Company is currently evaluating the provisions of ASU 2016-02 and its amendments, and assessing the impact the adoption of this guidance will have on its financial position, results of operations and disclosures. This process has included identifying the implementation team, applying the revised definition of a lease per ASC 842 to existing agreements, and from that information, creating a preliminary population. The Company intends to make the policy election to exclude all leases shorter than 12 months from the recognition of the recording of the right of use ("ROU") asset and related liabilities. The Company expects to elect the package of three practical expedients in regards to all leases that commenced before the effective date. The Company expects to make a policy election to not separate non-lease and lease components for all asset classes. The Company anticipates the adoption of this guidance will result in certain changes to its financial statements to add the related asset and liability accounts for all of its operating leases. The Company will continue to assess its agreements for any other impacts that may result from the adoption of this standard. During the fourth quarter of fiscal 2018, the Company plans to finalize its analysis of its population of lease agreements, including the classification of type of lease for each of those agreements, assess its current controls, update the overall lease policy, as well as identify and implement any changes that may be necessary to comply with the provisions of ASU 2016-02.
ASU 2016-02 becomes effective on April 1, 2019, and the Company expects to adopt the standard using the modified retrospective transition method, which will impact all leases existing at, or entered into after, the period of adoption. For all leases existing at the time of adoption the Company will recognize a cumulative effect adjustment to its opening balance of retained earnings as of April 1, 2019. The Company is still evaluating the final impact of this adoption method on its consolidated financial statements.
In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments in ASU 2016-13 will provide more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The ASU is effective for annual reporting periods beginning after December 15, 2019, including interim periods within that year. The Company is currently evaluating the impact, if any, the adoption of ASU 2016-13 may have on its consolidated financial statements.
In 2016, the FASB issued the following two ASU's on Statement of Cash Flows (Topic 230). Both amendments are effective for annual reporting periods beginning after December 15, 2017, including interim periods within that year.

• | In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The amendments in ASU 2016-15 provide more guidance towards the classification of multiple different types of cash flows in order to reduce the diversity in reporting across entities.

• | In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. The amendments in ASU 2016-18 explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows.

The Company adopted ASU 2016-15 and ASU 2016-18 effective April 1, 2018 and noted no significant impact to its consolidated financial statements.
In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. The amendments in ASU 2016-16 will improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. The ASU is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that year. The Company adopted ASU 2016-16 effective April 1, 2018 and noted no significant impact to its consolidated financial statements.
In February 2017, the FASB issued ASU 2017-05, Other Income - Gains and Losses from the Derecognition of Non-financial Assets (Subtopic 610-20). The amendments in ASU 2017-05 clarify the scope of Subtopic 610-20, Other Income-Gains and Losses from the Derecognition of Non-financial Assets, and to add guidance for partial sales of non-financial assets. Subtopic 610-20, which was issued in May 2014 as a part of ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), provides guidance for recognizing gains and losses from the transfer of non-financial assets in contracts with non-customers. The Company adopted ASU 2017-05 effective April 1, 2018 and adjusted the opening balance of accumulated deficit for $0.1 million for recognition of the deferred gain on the sale of the 64 Jackson Road building that occurred on March 28, 2018.
In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Subtopic 718) Scope of Modification Accounting. The amendments in ASU 2017-09 provide clarity and reduce both (1) diversity in practice and (2) cost and complexity
22

when applying the guidance in Topic 718, Compensation—Stock Compensation, to a change to the terms or conditions of a share-based payment award. The ASU is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those periods. The Company adopted ASU 2017-09 effective April 1, 2018 and noted no significant impact to its consolidated financial statements.
In July 2017, the FASB issued ASU 2017-11, Earnings per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), and Derivatives and Hedging (Topic 815). The amendments in ASU 2017-11 provide guidance for freestanding equity-linked financial instruments, such as warrants and conversion options in convertible debt or preferred stock, and should no longer be accounted for as a derivative liability at fair value as a result of the existence of a down round feature. The ASU is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those periods. The Company is currently evaluating the impact of the adoption of ASU 2017-11 and does not expect a significant impact on its consolidated financial statements, primarily due to the put option feature within the Company's warrant agreements which requires continued liability classification under ASC 480.
In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The amendments in ASU 2017-12 provide improved financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. In addition, the amendments in this update make certain targeted improvements to simplify the application of the hedge accounting guidance. The ASU is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those periods. The Company is currently evaluating the impact the adoption of ASU 2017-12 may have on its consolidated financial statements.
In June 2018, the FASB issued ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Non-Employee Share Based Payment Accounting. The amendments in ASU 2018-07 provide for the simplification of the measurement of share-based payment transactions for acquiring goods and services from non-employees. The ASU is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those periods. The Company is currently evaluating the impact of the adoption of ASU 2018-07 and does not expect it to have a significant impact on its consolidated financial statements.
In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in ASU 2018-13 provide for increased effectiveness of the disclosures made around fair value measurements while including consideration for costs and benefits. The ASU is effective for annual reporting periods beginning after December 15, 2019, including interim periods within those periods. The Company is currently evaluating the impact the adoption of ASU 2018-13 may have on its consolidated financial statements.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

ITEM 2. | MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). For this purpose, any statements contained herein that relate to future events or conditions, including without limitation, the statements in Part II, “Item 1A. Risk Factors” and in Part I under “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations” and located elsewhere herein regarding industry prospects, our prospective results of operations or financial position, adoption of accounting changes and expectations regarding the manufacture and installation of our REG system in Chicago, Illinois may be deemed to be forward-looking statements. Without limiting the foregoing, the words “believes,” “anticipates,” “plans,” “expects,” and similar expressions are intended to identify forward-looking statements. Such forward-looking statements represent management’s current expectations and are inherently uncertain. There are a number of important factors that could materially impact the value of our common stock or cause actual results to differ materially from those indicated by such forward-looking statements. These important factors include, but are not limited to: A significant portion of our revenues are derived from a single customer, Inox, and we cannot predict if and how successful Inox will be in executing on Solar Energy Corporation of India ("SECI") orders under the new central and state auction regime, and any related failure by Inox to succeed under this regime, or any delay in Inox’s ability to deliver its wind turbines, could result in fewer electrical control systems ("ECS") shipments to Inox; We have a history of operating losses and negative operating cash flows, which may continue in the future and require us to secure additional financing in the future; Our operating results may fluctuate significantly from quarter to quarter and may fall below expectations in any particular fiscal quarter; Our financial condition may have an adverse effect on our customer and supplier relationships; Lower prices for other fuel sources may reduce the demand for wind energy development, which could have a material adverse effect on our ability to grow our Wind business. Our success in addressing the wind energy market is dependent on the manufacturers that license our designs; Our success is dependent upon attracting and retaining qualified personnel and our inability to do so could significantly damage our business and prospects; We rely upon third-party suppliers for the components and sub-assemblies of many of our Wind and Grid products, making us vulnerable to supply shortages and price fluctuations, which could harm our business; Failure to achieve expected savings following the move of our former Devens, Massachusetts manufacturing facility could adversely impact our financial performance; We may not realize all of the sales expected from our backlog of orders and contracts; Our success depends upon the commercial use of high temperature superconductor products, which is currently limited, and a widespread commercial market for our products may not develop; Growth of the wind energy market depends largely on the availability and size of government subsidies, economic incentives and legislative programs designed to support the growth of wind energy; Our contracts with the U.S. government are subject to audit, modification or termination by the U.S. government and include certain other provisions in favor of the government, and additional funding of such contracts may not be approved by the U.S. Congress; Tax reform in the U.S. may negatively affect our operating results; We have operations in and depend on sales in emerging markets, including India, and global conditions could negatively affect our operating results or limit our ability to expand our operations outside of these markets; Our business and operations would be adversely impacted in the event of a failure or security breach of our information technology infrastructure; If we fail to maintain proper and effective internal control over financial reporting, our ability to produce accurate and timely financial statements could be impaired and may lead investors and other users to lose confidence in our financial data; We face risks related to our intellectual property; We face risks related to our legal proceedings; We face risks relating to our settlement with Sinovel; and the important factors discussed under the caption "Risk Factors" in Part 1.

Executive Overview
We are a leading provider of megawatt-scale solutions that lower the cost of wind power and enhance the performance of the power grid. In the wind power market, we enable manufacturers to field highly competitive wind turbines through our advanced power electronics products, engineering, and support services. In the power grid market, we enable electric utilities and renewable energy project developers to connect, transmit and distribute power through our transmission planning services and power electronics and superconductor-based products. Our wind and power grid products and services provide exceptional reliability, security, efficiency and affordability to our customers.
Our wind and power grid solutions help to improve energy efficiency, alleviate power grid capacity constraints and increase the adoption of renewable energy generation. Demand for our solutions is driven by the growing needs for renewable sources of electricity, such as wind and solar energy, and for modernized smart grids that improve power reliability, security and quality. Concerns about these factors have led to increased spending by corporations as well as supportive government regulations and initiatives on local, state, national and global levels, including renewable portfolio standards, tax incentives and international treaties.
We manufacture products using two proprietary core technologies: PowerModule™ programmable power electronic converters and our Amperium® high temperature superconductor (“HTS”) wires. These technologies and our system-level solutions are protected by a broad and deep intellectual property portfolio consisting of hundreds of patents and licenses worldwide.
We operate our business under two market-facing business units: Wind and Grid. We believe this market-centric structure enables us to more effectively anticipate and meet the needs of wind turbine manufacturers, power generation project developers and electric utilities.

• | Wind. Through our Windtec Solutions™, our Wind business segment enables manufacturers to field wind turbines with exceptional power output, reliability and affordability. We supply advanced power electronics and control systems, license our highly engineered wind turbine designs, and provide extensive customer support services to wind turbine manufacturers. Our design portfolio includes a broad range of drive trains and power ratings of 2 megawatts (“MW”) and higher. We provide a broad range of power electronics and software-based control systems that are highly integrated and designed for optimized performance, efficiency, and grid compatibility.

• | Grid. Through our Gridtec Solutions™, our Grid business segment enables electric utilities and renewable energy project developers to connect, transmit and distribute power with exceptional efficiency, reliability, security and affordability. We provide transmission planning services that allow us to identify power grid congestion, poor power quality, and other risks, which help us determine how our solutions can improve network performance. These services often lead to sales of our grid interconnection solutions for wind farms and solar power plants, power quality systems and transmission and distribution cable systems. We also sell ship protection products to the U.S. Navy through our Grid business segment.

Our fiscal year begins on April 1 and ends on March 31. When we refer to a particular fiscal year, we are referring to the fiscal year beginning on April 1 of that same year. For example, fiscal 2018 refers to the fiscal year beginning on April 1, 2018. Other fiscal years follow similarly.
On July 3, 2018, we and our wholly-owned subsidiaries Suzhou AMSC Superconductor Co. Ltd. (“AMSC China”) and AMSC Austria GmbH (“AMSC Austria”) entered into a settlement agreement (the “Settlement Agreement”) with Sinovel Wind Group Co., Ltd. (“Sinovel”). The Settlement Agreement settles the litigation and arbitration proceedings between us and Sinovel listed on Schedule 2 of the Settlement Agreement (the “Proceedings”), and any other civil claims, counterclaims, causes of action, rights and obligations directly or indirectly relating to the subject matters of the Proceedings and the contracts between us and Sinovel listed on Schedules 1 and 4 of the Settlement Agreement (the “Contracts”), subject to the exception described in Section 1.1 of the Settlement Agreement. The Settlement Agreement was filed as Exhibit 10.1 to the Company’s Form 8-K filed with the Securities and Exchange Commission on July 9, 2018. Under the terms of the Settlement Agreement, Sinovel agreed to pay AMSC China an aggregate cash amount in Renminbi (“RMB”) equivalent to $57.5 million, consisting of two installments. Sinovel paid the first installment of the RMB equivalent of $32.5 million on July 4, 2018, and paid the second installment of the RMB equivalent of $25.0 million on December 27, 2018.
25

In addition, pursuant to the terms of the Settlement Agreement, we and AMSC Austria have granted Sinovel a non-exclusive license for certain of our intellectual property to be used solely in Sinovel’s doubly fed wind turbines (the “License”). We have agreed not to sue Sinovel, Sinovel’s power converter suppliers or Sinovel’s customers for use of the technology covered by the License.
On July 25, 2018, we received notice from BASF Corporation (“BASF”) that BASF will not be extending the term of the Joint Development Agreement dated March 4, 2016 (“JDA”) by and between BASF and us beyond March 3, 2019. As a result, BASF will not be required to pay $1.0 million in 2019 to us as otherwise would have been required pursuant to the terms of the JDA. To date, BASF has paid $6.0 million to us under the JDA.
On October 31, 2018, we entered into a Subcontract Agreement with Commonwealth Edison Company (“ComEd”) (the “Subcontract Agreement”) for the manufacture and installation of the Company’s resilient electric grid (“REG”) system within ComEd’s electric grid in Chicago, Illinois (the “Project”). As provided in the Subcontract Agreement, the Subcontract Agreement will become effective upon the signing of an amendment by us and the U.S. Department of Homeland Security (“DHS”) to the existing contract (the “Prime Contract”) between ourselves and DHS. Unless terminated earlier by ourselves or DHS according to the terms of the Subcontract Agreement, the term of the Subcontract Agreement will continue until we complete our warranty obligations under the Subcontract Agreement. Under the terms of the Subcontract Agreement, we have agreed, among other things, to provide the REG system and to supervise ComEd’s installation of the REG system in Chicago. As part of our separate cost sharing arrangement with DHS under the Prime Contract, we expect funding provided by DHS in connection with the Subcontract Agreement to be between $9.0 to $11.0 million, which represents the total amount of revenue we are expected to recognize over the term of the Subcontract Agreement and includes up to $1.0 million that we have agreed to reimburse ComEd for costs incurred by ComEd while undertaking its tasks under the Subcontract Agreement (the "Reimbursement Amount”). In addition, we have agreed to deliver an irrevocable letter of credit in the amount of $5.0 million to secure certain Company obligations under the Subcontract Agreement. ComEd has agreed to provide the site and provide all civil engineering work required to support the installation, operation and integration of the REG system into ComEd’s electric grid. Other than the Reimbursement Amount, ComEd is responsible for its own costs and expenses. Construction of the Project is expected to commence within six months after DHS’s approval. The REG system is expected to be operational by 2021.
Critical Accounting Policies and Estimates
The preparation of the unaudited condensed consolidated financial statements requires that we make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ under different assumptions or conditions. Effective April, 1 2018, we adopted ASU 2014-09, which provides for new requirements in regards to revenue recognition. See Note 2, "Revenue Recognition" for further details. Aside from the adoption of ASU 2014-09, there were no significant changes in the critical accounting policies that were disclosed in our Form 10-K for fiscal 2017, which ended on March 31, 2018.
Results of Operations
Three and nine months ended December 31, 2018 compared to the three and nine months ended December 31, 2017
Revenues
Total revenues decreased 5% and increased 19% to $14.1 million and $41.6 million, respectively, for the three and nine months ended December 31, 2018, compared to $14.9 million and $34.9 million for the three and nine months ended December 31, 2017. Our revenues are summarized as follows (in thousands):

| Three months ended December 31, |  | Nine months ended December 31,
| 2018 |  | 2017 |  | 2018 |  | 2017
Revenues: |  |  |  |  |  |  |  |  |
Wind | $ | 7,308 |  |  | $ | 2,633 |  |  | $ | 18,293 |  |  | $ | 10,465 |
Grid | 6,826 |  |  | 12,300 |  |  | 23,325 |  |  | 24,439 |
Total | $ | 14,134 |  |  | $ | 14,933 |  |  | $ | 41,618 |  |  | $ | 34,904 |

Our Wind business unit accounted for 52% and 44% of total revenues for the three and nine months ended December 31, 2018, compared to 18% and 30% for the three and nine months ended December 31, 2017. Revenues in the Wind business unit increased 178% and 75% to $7.3 million and $18.3 million in the three and nine months ended December 31, 2018, from $2.6
26

million and $10.5 million in the three and nine months ended December 31, 2017. Wind business unit revenues increased due to increased ECS shipments to Inox during the 2018 periods. Inox has been active in the new central and state government auction regime in India and has over 900 MW of orders from the first four SECI central government auctions, and 50 MW from the Maharashtra state government auction. However, we cannot predict if and how successful Inox will be in executing on these orders or in obtaining new orders under the new central and state auction regime. Any failure by Inox to succeed under this regime, or any delay in Inox’s ability to deliver its wind turbines, could result in fewer ECS shipments to Inox.
Our Grid business unit accounted for 48% and 56% of total revenues for the three and nine months ended December 31, 2018, compared to 82% and 70% for the three and nine months ended December 31, 2017. Our Grid business unit revenues decreased 45% and 5% to $6.8 million and $23.3 million in the three and nine months ended December 31, 2018, from $12.3 million and $24.4 million in the three and nine months ended December 31, 2017. Grid business unit revenues decreased primarily due to lower D-VAR system revenues in the three months ended December 31, 2018 compared to the prior year period and lower revenue from projects with the U.S. Navy in the nine months ended December 31, 2018, compared to the prior year period.
The following table sets forth customers who represented 10% or more of our total revenues for the three and nine months ended December 31, 2018 and 2017:

| Reportable |  | Three months ended December 31, |  | Nine months ended December 31,
| Segment |  | 2018 |  | 2017 |  | 2018 |  | 2017
Inox Wind Limited | Wind |  | 47 | % |  | 15 | % |  | 40 | % |  | 27 | %
Vestas | Grid |  | <10 % |  |  | 27 | % |  | 15 | % |  | 11 | %
SSE Generation Ltd. | Grid |  | <10 % |  |  | 17 | % |  | <10 % |  |  | <10 % |
Fuji Bridex Pte Ltd | Grid |  | 17 | % |  | — | % |  | <10 % |  |  | — | %

Cost of Revenues and Gross Margin
Cost of revenues increased by 5% to $10.4 million for the three months ended December 31, 2018, compared to $9.9 million for the three months ended December 31, 2017. Cost of revenues decreased by 11% to $30.4 million for the nine months ended December 31, 2018, compared to $34.1 million for the nine months ended December 31, 2017. Gross margin was 26% for the three months ended December 31, 2018, compared to 34% for the three months ended December 31, 2017. Gross margin was 27% for the nine months ended December 31, 2018, compared to 2% for the nine months ended December 31, 2017. The decrease in gross margin in the three month period was driven by a less favorable product mix. The increase in gross margin in the nine month period was due to lower depreciation and reduced fixed factory overhead.
Operating Expenses
Research and development
R&D expenses decreased in the three and nine months ended December 31, 2018 by 18% and 13% to $2.5 million and $7.6 million from $3.0 million and $8.7 million for the three and nine months ended December 31, 2017. The decreases in R&D expenses were primarily due to decreased compensation expense.
Selling, general, and administrative
SG&A expenses decreased by 3% and 4% to $5.3 million and $16.3 million in the three and nine months ended December 31, 2018, from $5.5 million and $17.0 million in the three and nine months ended December 31, 2017. The decrease in SG&A expenses was due primarily to reduced overall compensation expense.
Gain on Sinovel settlement
We recorded a gain of $25.0 million and $53.7 million, net of legal and other direct costs, in the three and nine months ended December 31, 2018, respectively, as a result of the receipt of the payments from Sinovel required by the Settlement Agreement.
Amortization of acquisition related intangibles
We recorded amortization expense related to our core technology and know-how, trade names and trademark intangible assets of $0.1 million and $0.3 million in the three and nine months ended December 31, 2018, and $0.1 million in each of the three and nine months ended December 31, 2017.
27

Restructuring
We recorded less than $0.1 million and $0.4 million for facility exit costs in the three and nine months ended December 31, 2018 as a result of the move of the corporate office that was announced as part of our April 4, 2017 approved restructuring plan. We recorded a restructuring charge of $1.3 million for severance costs in the nine months ended December 31, 2017 as a result of the reduction in force also announced on April 4, 2017. Included in the $1.3 million severance pay charged to operations in the nine months ended December 31, 2017, is $0.5 million of severance pay for one of our former executive officers pursuant to the terms of a severance agreement dated June 30, 2017. Under the terms of the severance agreement, our former executive officer was entitled to eighteen months of his base salary, which was paid in cash by December 31, 2018.
Operating profit/(loss)
Our operating profit/(loss) is summarized as follows (in thousands):

| Three months ended December 31, |  | Nine months ended December 31,
| 2018 |  | 2017 |  | 2018 |  | 2017
Operating profit/(loss): |  |  |  |  |  |  |
Wind | $ | 24,269 |  |  | $ | (1,684 | ) |  | $ | 51,419 |  |  | $ | (7,557 | )
Grid | (2,665 | ) |  | (1,011 | ) |  | (8,202 | ) |  | (15,279 | )
Unallocated corporate expenses | (839 | ) |  | (1,156 | ) |  | (2,851 | ) |  | (3,514 | )
Total | $ | 20,765 |  |  | $ | (3,851 | ) |  | $ | 40,366 |  |  | $ | (26,350 | )

Our Wind segment generated operating income of $24.3 million and $51.4 million in the three and nine months ended December 31, 2018, compared to losses of $1.7 million and $7.6 million in the three and nine months ended December 31, 2017. The increase in the Wind business unit operating income was due primarily to the receipt of the payments from Sinovel required by the Settlement Agreement, as well as increased shipments of ECS to Inox.
Our Grid segment generated operating losses of $2.7 million and $8.2 million in the three and nine months ended December 31, 2018, compared to losses of $1.0 million and $15.3 million in the three and nine months ended December 31, 2017. The increase in the Grid business unit operating losses in the three month period was primarily due to decreased revenues, as discussed above. The decrease in the Grid business unit operating losses in the nine month period was due primarily to lower depreciation and lower operating expenses compared to the prior year period.
Unallocated corporate expenses primarily consist of stock-based compensation expense of $0.8 million and $0.9 million, in the three months ended December 31, 2018 and 2017, respectively and restructuring charges of less than $0.1 million in both periods. Unallocated corporate expenses primarily consist of stock-based compensation expense of $2.4 million and $2.1 million and restructuring charges of $0.4 million and $1.3 million included in the nine months ended December 31, 2018 and 2017, respectively, as well as a gain for the change in fair value of contingent consideration of $0.3 million and $0.1 million in the three and nine months ended December 31, 2017, respectively.
Change in fair value of warrants
The change in fair value of warrants resulted in losses of $2.5 million and $2.7 million in the three and nine months ended December 31, 2018, compared to gains of $0.4 million and $1.5 million in the three and nine months ended December 31, 2017. The change in the fair value was primarily driven by changes in stock price, which is a key valuation metric.
Minority Interest
The gain on sale of minority interest was $0.1 million in each of the three and nine months ended December 31, 2018, compared to no gain and a gain of $1.0 million in the three and nine months ended December 31, 2017, respectively. The gain on sale in the 2018 periods was driven by receipt of the final payment from the sale of our minority interest in Blade Dynamics.
Interest income, net
28

Interest income, net, was $0.3 million and $0.8 million in the three and nine months ended December 31, 2018, compared to less than $0.1 million and $0.1 million in the three and nine months ended December 31, 2017. The increase in interest income in each of the 2018 periods was primarily related to higher cash balances earning higher interest rates than in prior periods.
Other income (expense), net
Other income (expense), net, was income of $0.1 million and $1.1 million in the three and nine months ended December 31, 2018, compared to expense of $0.3 million and $2.4 million in the three and nine months ended December 31, 2017. The increase in other income, net, during the three and nine months ended December 31, 2018, was primarily driven by higher foreign currency gains.
Income Taxes
Income tax expense was $1.6 million and $4.5 million in the three and nine months ended December 31, 2018, compared to income tax expense of $0.6 million and $0.5 million in the three and nine months ended December 31, 2017. The increase in income tax expense in the three months ended December 31, 2018 as compared to December 31, 2017 is due primarily to taxable income in foreign jurisdictions. The increase in income tax expense in the nine months ended December 31, 2018 as compared to December 31, 2017 was primarily due to the repayment of previously reserved intercompany trade balances due to AMSC Austria from AMSC China and a dividend paid by AMSC Austria to the parent company in the nine months ended December 31, 2018 following the Sinovel settlement.
Non-GAAP Measures
Generally, a non-GAAP financial measure is a numerical measure of a company’s performance, financial position or cash flow that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. The non-GAAP measures included in this Form 10-Q, however, should be considered in addition to, and not as a substitute for or superior to the comparable measure prepared in accordance with GAAP.
We define non-GAAP net loss as net loss before sale of minority investments, stock-based compensation, gain on Sinovel settlement, net, amortization of acquisition-related intangibles, changes in fair value of warrants and contingent consideration, non-cash interest expense, tax effect of adjustments, and the other non-cash or unusual charges, indicated in the table below. We believe non-GAAP net loss assists management and investors in comparing our performance across reporting periods on a consistent basis by excluding these non-cash or non-recurring charges that we do not believe are indicative of our core operating performance. A reconciliation of GAAP to non-GAAP net loss is set forth in the table below (in thousands, except per share data):

| Three months ended December 31, |  | Nine months ended December 31,
| 2018 |  | 2017 |  | 2018 |  | 2017
Net income (loss) | $ | 17,293 |  |  | $ | (4,248 | ) |  | $ | 35,114 |  |  | $ | (26,782 | )

Weighted average shares outstanding - basic | 20,419 |  |  | 19,949 |  |  | 20,300 |  |  | 18,614 |

We incurred non-GAAP net losses of $2.3 million and $8.4 million or $0.11 and $0.41 per share, for the three and nine months ended December 31, 2018, compared to non-GAAP net losses of $3.4 million and $26.8 million or $0.17 and $1.44 per share for the three and nine months ended December 31, 2017. The decrease in non-GAAP net loss for the nine months ended
29

December 31, 2018 as compared to the nine months ended December 31, 2017 was driven primarily by an increase in net income driven by higher revenues, as well as lower depreciation and operating costs.
We define non-GAAP operating cash flow as operating cash flow before: the gain on Sinovel settlement (net of legal fees and expenses); tax effect of adjustments; and other unusual cash flows or items. We believe non-GAAP operating cash flow assists management and investors in comparing our operating cash flow across reporting periods on a consistent basis by excluding these non-recurring cash items that it does not believe are indicative of our core operating cash flow. A reconciliation of GAAP to non-GAAP operating cash flow is set forth in the table below (in thousands).

| Three months ending |  | Nine months ending
| December 31, 2018 |  | December 31, 2018
Operating cash flow | $24,191 |  | $47,786
Sinovel settlement (net of legal fees and expenses) | (24,388 | ) |  | (54,724 | )
Tax effect of adjustments | 1,130 |  |  | 2,377 |
Non-GAAP operating cash flow | $933 |  | $(4,561)

Liquidity and Capital Resources
We have experienced recurring operating losses and as of December 31, 2018 had an accumulated deficit of $953.2 million. In addition, although we generated positive operating cash flows in the nine month period ended December 31, 2018, we have historically experienced recurring negative operating cash flows. Although our sales to Inox increased in the nine months ended December 31, 2018 compared to the nine months ended December 31, 2017, we cannot predict if and how successful Inox will be in executing on SECI orders or in obtaining additional orders under the new central and state auction regime. Any failure by Inox to succeed under this regime, or any delay in Inox’s ability to deliver its wind turbines, could result in fewer ECS shipments to Inox.
Our cash requirements depend on numerous factors, including whether Inox is successful under the new central and state auction regime as noted above, the successful completion of our product development activities, our ability to commercialize our Resilient Electric Grid (“REG”) and ship protection system solutions, the rate of customer and market adoption of our products, collecting receivables according to established terms, and the continued availability of U.S. government funding during the product development phase of our superconductor-based products. We continue to closely monitor our expenses and, if required, expect to further reduce our operating and capital spending to enhance liquidity.
As of December 31, 2018, we had cash, cash equivalents, and restricted cash of $80.2 million, compared to $34.2 million as of March 31, 2018, an increase of $46.0 million. As of December 31, 2018, we had approximately $28.7 million of cash, cash equivalents, and restricted cash in foreign bank accounts. Our cash and cash equivalents, and restricted cash are summarized as follows (in thousands):

| December 31, 2018 |  | March 31, 2018
Cash and cash equivalents | $ | 80,042 |  |  | $ | 34,084 |
Restricted cash | 165 |  |  | 165 |
Total cash, cash equivalents, and restricted cash | $ | 80,207 |  |  | $ | 34,249 |

For the nine months ended December 31, 2018, net cash provided by operating activities was $47.8 million compared to $20.2 million of net cash used for the nine months ended December 31, 2017. The increase in net cash provided by operations was due primarily to the receipt of the full amount of the Sinovel settlement.
For the nine months ended December 31, 2018, net cash used in investing activities was $0.7 million, compared to net cash used in investing activities of $1.1 million for the nine months ended December 31, 2017. The decrease in net cash used in investing activities was due primarily to increased purchases of property, plant and equipment in the nine months ended December 31, 2017 related to the Devens facility move offset partially by a decrease in the proceeds from the sale of our minority interest in Blade Dynamics in the current year period as compared to the prior year period.
For the nine months ended December 31, 2018, net cash used in financing activities was $0.4 million compared to net cash provided by financing activities of $15.2 million in the nine months ended December 31, 2017. The decrease in net cash provided

by financing activities was primarily due to net proceeds of $17.0 million from the issuance of 4.6 million shares of common stock in May 2017, with no such equity offering in the current year period.
As of December 31, 2018, we had $0.2 million of restricted cash included in long-term assets. These amounts included in restricted cash primarily represent deposits to secure letters of credit for various supply contracts. These deposits are held in interest bearing accounts.
We believe we have sufficient available liquidity to fund our operations and capital expenditures for the next twelve months. In addition, we may seek to raise additional capital, which could be in the form of loans, convertible debt or equity, to fund our operating requirements and capital expenditures. Our liquidity is highly dependent on our ability to increase revenues, including our ability to collect revenues under our agreements with Inox, control our operating costs, and our ability to raise additional capital, if necessary. There can be no assurance that we will be able to raise additional capital, on favorable terms or at all, or execute on any other means of improving our liquidity as described above.
Legal Proceedings
We are involved in legal and administrative proceedings and claims of various types. See Part II, Item 1, “Legal Proceedings,” for additional information. We record a liability in our consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. We review these estimates each accounting period as additional information is known and adjust the loss provision when appropriate. If a matter is both probable to result in liability and the amounts of loss can be reasonably estimated, we estimate and disclose the possible loss or range of loss to the extent necessary to make the consolidated financial statements not misleading. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in our consolidated financial statements.
Off-Balance Sheet Arrangements
We do not have any off-balance sheet arrangements, as defined under SEC rules, such as relationships with unconsolidated entities or financial partnerships, which are often referred to as structured finance or special purpose entities, established for the purpose of facilitating transactions that are not required to be reflected on our balance sheet except as discussed below.
We occasionally enter into construction contracts that include a performance bond. As these contracts progress, we continually assess the probability of a payout from the performance bond. Should we determine that such a payout is probable, we would record a liability.
In addition, we have various contractual arrangements in which minimum quantities of goods or services have been committed to be purchased on an annual basis.
Recent Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board (“FASB”) and the International Accounting Standards Board ("IASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606). The guidance substantially converges final standards on revenue recognition between the FASB and IASB providing a framework on addressing revenue recognition issues and, upon its effective date, replaces almost all existing revenue recognition guidance, including industry-specific guidance, in current U.S. generally accepted accounting principles. The FASB has subsequently issued multiple amendments to ASU 2014-09 which are all effective for annual reporting periods beginning after December 15, 2017.
As of April 1, 2018, we have adopted ASU 2014-09 and its amendments, reported the impact in our consolidated financial statements, and implemented changes to our business processes, systems and controls to support revenue recognition and the related disclosures under this ASU. Our assessment included a detailed review of representative contracts from each of our revenue streams and a comparison of our historical accounting policies and practices to the new standard. We adopted the new standards retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the modified retrospective transition method) to all existing contracts that have remaining obligations as of April 1, 2018. Accordingly, we have elected to retroactively adjust only those contracts that do not meet the definition of a complete contract at the date of the initial application. This guidance will lead to recognizing certain revenue transactions sooner than in the past on certain contracts, as we will need to estimate the revenue we will be entitled to upon contract completion, and later on other contracts, such as Consulting and Statement of Work transactions, due to the lack of an enforceable right to payment for performance obligations satisfied over time. There are no changes in the accounting for our largest revenue stream which includes Inox Wind Ltd as our primary customer. Across other revenue streams such as D-VAR® Equipment and D-VAR® Turnkey, the timing of
31

revenue recognition will be affected for multiple types of contracts, primarily multiple performance obligation contracts in our Grid business unit, but those differences did not have a material impact on our consolidated financial statements. The adjustment to opening retained earnings was not significant for the period commencing on April 1, 2018. Additionally, the adoption of this new standard is not expected to have any tax impact on the consolidated financial statements. As part of this analysis, we evaluated our information technology capabilities and systems, and did not incur significant information technology costs to modify systems currently in place.
In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in ASU 2016-01 enhance the reporting model for financial instruments to provide users of financial statements with more decision-useful information. This ASU is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those fiscal years. We adopted ASU 2016-01 effective April 1, 2018 and noted no significant impact to our consolidated financial statements.
In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The guidance in this ASU supersedes the leasing guidance in Topic 840, Leases. Under the new guidance, lessees are required to recognize lease assets and lease liabilities on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. This ASU and its amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.

• | In July 2018, the FASB issued ASU 2018-10, Codification improvements to Topic 842, Leases. The amendments in ASU 2018-10 provide more clarification in regards to the application and requirements of ASU 2016-02.

• | In July 2018, the FASB issued ASU 2018-11, Topic 842, Leases - Targeted improvements. The amendments in ASU 2018-11 provide for the option to adopt the standard prospectively and recognize a cumulative-effect adjustment to the opening balance of retained earnings as well as offer a new practical expedient that will allow us to elect, by class of underlying asset, to not separate non-lease and lease components in certain circumstances and instead to account for those components as a single item.

We are currently evaluating the provisions of ASU 2016-02 and its amendments, and assessing the impact the adoption of this guidance will have on our financial position, results of operations and disclosures. This process has included identifying the implementation team, applying the revised definition of a lease per Accounting Standards Codification ("ASC") 842 to existing agreements and, from that information, creating a preliminary population. We intend to make the policy election to exclude all leases shorter than 12 months from the recognition of the recording of the right of use ("ROU") asset and related liabilities. We expect to elect the package of three practical expedients in regards to all leases that commenced before the effective date. We expect to make a policy election to not separate non-lease and lease components for all asset classes. We anticipate the adoption of this guidance will result in certain changes to our financial statements to add the related asset and liability accounts for all of our operating leases. We will continue to assess our agreements for any other impacts that may result from the adoption of this standard. During the fourth quarter of fiscal 2018, we plan to finalize our analysis of our population of lease agreements, including the classification of type of lease for each of those agreements, assess our current controls, update the overall lease policy as well as identify and implement any changes that may be necessary to comply with the provisions of ASU 2016-02.
ASU 2016-02 becomes effective on April 1, 2019, and we expect to adopt the new standard using the modified retrospective transition method, which will impact all leases existing at, or entered into after the period of adoption. For all leases existing at the time of adoption we will recognize a cumulative effect adjustment to the opening balance of retained earnings as of April 1, 2019. We are still evaluating the final impact of this adoption method on our consolidated financial statements.
In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments in ASU 2016-13 provide more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The ASU is effective for annual reporting periods beginning after December 15, 2019, including interim periods within that year. We are currently evaluating the impact, if any, the adoption of ASU 2016-13 may have on our consolidated financial statements.
In 2016, the FASB issued the following two ASU's on Statement of Cash Flows (Topic 230). Both amendments are effective for annual reporting periods beginning after December 15, 2017, including interim periods within that year.

• | In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The amendments in ASU 2016-15 provide more guidance towards the classification of multiple different types of cash flows in order to reduce the diversity in reporting across entities.

32

• | In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cas h. The amendments in ASU 2016-18 explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows.

We adopted ASU 2016-15 and ASU 2016-18 effective April 1, 2018 and noted no significant impact to our consolidated financial statements.
In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. The amendments in ASU 2016-16 improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. The ASU is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that year. We adopted of ASU 2016-16 effective April 1, 2018 and noted no significant impact to our consolidated financial statements.
In February 2017, the FASB issued ASU 2017-05, Other Income - Gains and Losses from the Derecognition of Non-financial Assets (Subtopic 610-20). The amendments in ASU 2017-05 clarify the scope of Subtopic 610-20, Other Income-Gains and Losses from the Derecognition of Non-financial Assets, and to add guidance for partial sales of non-financial assets. Subtopic 610-20, which was issued in May 2014 as a part of ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), provides guidance for recognizing gains and losses from the transfer of non-financial assets in contracts with non-customers. We adopted ASU 2017-05 effective April 1, 2018 and adjusted the opening balance of accumulated deficit for $0.1 million for recognition of the deferred gain on the sale of the 64 Jackson Road building that occurred on March 28, 2018.
In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Subtopic 718) Scope of Modification Accounting. The amendments in ASU 2017-09 provide clarity and reduce both (1) diversity in practice and (2) cost and complexity when applying the guidance in Topic 718, Compensation—Stock Compensation, to a change to the terms or conditions of a share-based payment award. The ASU is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those periods. We adopted ASU 2017-09 effective April 1, 2018 and noted no significant impact to our consolidated financial statements.
In July 2017, the FASB issued ASU 2017-11, Earnings per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), and Derivatives and Hedging (Topic 815). The amendments in ASU 2017-11 provide guidance for freestanding equity-linked financial instruments, such as warrants and conversion options in convertible debt or preferred stock, and should no longer be accounted for as a derivative liability at fair value as a result of the existence of a down round feature. The ASU is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those periods. We are currently evaluating the impact of the adoption of ASU 2017-11 and do not expect a significant impact on our consolidated financial statements, primarily due to the put option feature which requires continued liability classification under ASC 840.
In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The amendments in ASU 2017-12 provide improved financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. In addition, the amendments in this update make certain targeted improvements to simplify the application of the hedge accounting guidance. The ASU is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those periods. We are currently evaluating the impact the adoption of ASU 2017-12 may have on our consolidated financial statements.
In June 2018, the FASB issued ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Non-Employee Share Based Payment Accounting. The amendments in ASU 2018-07 provide for the simplification of the measurement of share-based payment transactions for acquiring goods and services from non-employees. The ASU is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those periods. We are currently evaluating the impact of the adoption of ASU 2018-07 and do not expect it to have a significant impact on our consolidated financial statements.
In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in ASU 2018-13 provide for increased effectiveness of the disclosures made around fair value measurements while including consideration for costs and benefits. The ASU is effective for annual reporting periods beginning after December 15, 2019, including interim periods within those periods. We are currently evaluating the impact the adoption of ASU 2018-13 may have on our consolidated financial statements.
We do not believe that, outside of those disclosed here, there are any other recently issued accounting pronouncements that will have a material impact on our consolidated financial statements.

ITEM 4. | CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2018. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on that evaluation of our disclosure controls and procedures as of December 31, 2018, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.
Changes in Internal Control over Financial Reporting
There were no changes to our internal controls over financial reporting during the quarter ended December 31, 2018, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 1A. | RISK FACTORS

Except as noted below there have been no material changes to the risk factors described in Part I, Item IA of our Annual Report on Form 10-K for the fiscal year ended March 31, 2018, filed with the SEC on June 6, 2018.
We face risks relating to our settlement with Sinovel.
On July 3, 2018, we and our wholly-owned subsidiaries AMSC China and AMSC Austria entered into a Settlement Agreement with Sinovel. The Settlement Agreement settles the litigation and arbitration proceedings between us and Sinovel, as further described elsewhere in this Quarterly Report. Under the terms of the Settlement Agreement, Sinovel agreed to pay AMSC China an aggregate cash amount in Renminbi (RMB) equivalent to $57.5 million, consisting of two installments. Sinovel paid the first installment of the RMB equivalent of $32.5 million on July 4, 2018, and paid the second installment of the RMB equivalent of $25.0 million on December 27, 2018. There is no assurance that the relevant taxing authorities will agree with our assessment of the taxes that will be required in relation to the foregoing payments. In the event that the relevant taxing authorities disagree with our tax treatment of the settlement, our cash flows and financial position may be materially adversely affected.
