Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 22. Commitments and Contingencies Service Agreements Under the provisions of its service agreements, the Company provides services to maintain, monitor, and repair customer power plants to meet minimum operating levels. Under the terms of such service agreements, the particular power plant must meet a minimum operating output during defined periods of the term. If minimum output falls below the contract requirement, the Company may be subject to performance penalties and/or may be required to repair or replace the customer’s fuel cell module(s). Power Purchase Agreements Under the terms of the Company’s PPAs, customers agree to purchase power from the Company’s fuel cell power plants at negotiated rates. Electricity rates are generally a function of the customers’ current and estimated future electricity pricing available from the grid. As owner or lessee of the power plants, the Company is responsible for all operating costs necessary to maintain, monitor and repair the power plants. Under certain agreements, the Company is also responsible for procuring fuel, generally natural gas or Biogas, to run the power plants. In addition, under the terms of some of the PPAs, the Company may be subject to a performance penalty if the Company does not meet certain performance requirements. Other As of October 31, 2020, the Company had unconditional purchase commitments aggregating $34.7 million, for materials, supplies and services in the normal course of business. Legal Proceedings SEC Proceedings Between August 2005 and April 2017, we sold shares of our common stock pursuant to a series of “at-the-market” sales plans. The shares sold pursuant to these sales plans represented a portion of the shares registered by us pursuant to shelf registration statements we filed with the SEC during this time period. While we reported the number of shares we had sold, along with the net proceeds earned by us from those sales made during each fiscal quarter pursuant to the sales plans in our annual and quarterly reports on Forms 10-K and 10-Q, we omitted from the shelf registration statements certain information about the offerings, including the specific plan of distribution and the nature and terms of compensation or other agreements with any underwriters, dealers, or agents, and for some offerings, also omitted the specific type and quantity of securities offered; and we did not file or deliver prospectus supplements at the time of or prior to making these sales or otherwise timely disclose the information that had been omitted from the shelf registration statements, as is required by SEC regulations. In 2018, we reported to the SEC Staff these sales and our failure to file or deliver prospectus supplements, and in response to our report, the SEC Staff opened an informal investigation of these sales. Following our self-report and the investigation by the SEC Staff and pursuant to our Offer of Settlement, on September 3, 2020, the SEC entered an order instituting cease-and-desist proceedings pursuant to Section 8A of the Securities Act, finding that we had violated Section 5(b)(2) of the Securities Act with respect to these sales and requiring us to cease and desist from committing or causing any violations and any future violations of Section 5(b)(2) but not imposing any civil penalties or disgorgement. Under the terms of the settlement, we consented to the entry of the order and neither admitted nor denied any of the SEC’s findings. Such a settlement, without a waiver by the SEC, would disqualify us from relying on the safe harbors from registration under the Securities Act set forth in Regulation A, Regulation D and Regulation Crowdfunding, following the effective date of the settlement. Accordingly, we submitted an application to the SEC for a waiver of disqualification under Regulation A and Regulation D. We did not seek a waiver under Regulation Crowdfunding as we do not expect to rely on crowdfunding in raising capital. On September 3, 2020, the SEC Staff granted the requested waivers with respect to Regulation A and Regulation D pursuant to delegated authority. POSCO Energy Matters From approximately 2007 through 2015, we relied on POSCO Energy to develop and grow the South Korean and Asian markets for our products and services. We received upfront license payments and were entitled to receive royalty income from POSCO Energy pursuant to certain manufacturing and technology transfer agreements, including the Alliance Agreement dated February 7, 2007 (and the amendments thereto), the Technology Transfer, License and Distribution Agreement dated February 7, 2007 (and the amendments thereto), the Stack Technology Transfer and License Agreement dated October 27, 2009 (and the amendments thereto), and the Cell Technology Transfer and License Agreement dated October 31, 2012 (and the amendments thereto), which are collectively referred to herein as the “License Agreements”. The License Agreements provided POSCO Energy with the exclusive technology rights to manufacture, sell, distribute and service our SureSource 300, SureSource 1500 and SureSource 3000 fuel cell technology in the South Korean and broader Asian markets. Due to certain actions and inactions of POSCO Energy, the Company has not realized any new material revenues, royalties or new projects developed by POSCO Energy since late 2015. In November 2019, POSCO Energy spun-off its fuel cell business into a new entity, Korea Fuel Cell Co., Ltd. (“KFC”), without the Company’s consent. As part of the spin-off, POSCO Energy transferred manufacturing and service rights under the License Agreements to KFC, but retained distribution rights and severed its own liability under the License Agreements. The Company formally objected to POSCO Energy’s spin-off, and POSCO Energy posted a bond to secure any liabilities to the Company arising out of the spin-off. In September 2020, the Korean Electricity Regulatory Committee found that POSCO Energy’s spin-off of the fuel cell business to KFC may have been done in violation of South Korean law. On February 19, 2020, the Company notified POSCO Energy in writing that it was in material breach of the License Agreements by (i) its actions in connection with the spin-off of the fuel cell business to KFC, (ii) its suspension of performance through its cessation of all sales activities since late 2015 and its abandonment of its fuel cell business in Asia, and (iii) its disclosure of material nonpublic information to third parties and its public pronouncements about the fuel cell business on television and in print media that have caused reputational damage to the fuel cell business, the Company and its products. The Company also notified POSCO Energy that, under the terms of the License Agreements, it had 60 days to fully cure its breaches to the Company’s satisfaction and that failure to so cure would lead to termination of the License Agreements. Further, on March 27, 2020, the Company notified POSCO Energy of additional instances of its material breach of the License Agreements based on POSCO Energy’s failure to pay royalties required to be paid in connection with certain module replacements. On April 27, 2020, POSCO Energy initiated a series of three arbitration demands against the Company at the International Court of Arbitration of the International Chamber of Commerce seated in Singapore alleging certain warranty defects in a sub-megawatt conditioning facility at its facility in Pohang, South Korea and seeking combined damages of approximately $3.3 million. Prior to filing the arbitrations, POSCO Energy obtained provisional attachments from the Seoul Central District Court attaching certain revenues owed to the Company by Korea Southern Power Company (“KOSPO”) as part of such warranty claims, which has delayed receipt of certain payments owed to the Company. POSCO Energy subsequently sought additional provisional attachments on KOSPO revenues from the Seoul Central District Court based on unspecified warranty claims not yet filed in an additional amount of approximately $7 million, and additional provisional attachments on KOSPO revenues from the Seoul Central District Court based on its alleged counterclaims in the license termination arbitration described below in an additional amount of approximately $110 million. As of October 31, 2020, outstanding accounts receivable due from KOSPO were $4.8 million. On June 28, 2020, the Company terminated the License Agreements with POSCO Energy and filed a demand for arbitration against POSCO Energy and KFC in the International Court of Arbitration of the International Chamber of Commerce based on POSCO Energy’s (i) failure to exercise commercially reasonable efforts to sell the Company’s technology in the South Korean and Asian markets, (ii) disclosure of the Company’s proprietary information to third parties, (iii) attack on the Company’s stock price and (iv) spin-off of POSCO Energy’s fuel cell business into KFC without the Company’s consent. The Company has requested that the arbitral tribunal (a) confirm through declaration that POSCO Energy’s exclusive license to market the Company’s technology and products in South Korea and Asia is null and void as a result of the breaches of the License Agreements and that the Company has the right to pursue direct sales in these markets, (b) order POSCO Energy and KFC to compensate the Company for losses and damages suffered in the amount of more than $200 million, and (c) order POSCO Energy and KFC to pay the Company’s arbitration costs, including counsel fees and expenses. The Company has retained outside counsel on a contingency basis to pursue its claims, and outside counsel has entered into an agreement with a litigation finance provider to fund the legal fees and expenses of the arbitration. In October 2020, POSCO Energy filed a counterclaim in the arbitration (x) seeking approximately $880 million in damages based on allegations that the Company misrepresented the capabilities of its fuel cell technology to induce POSCO Energy to enter into the License Agreements and failed to turn over know-how sufficient for POSCO Energy to successfully operate its business; (y) seeking a declaration that the License Agreements remain in full force and effect and requesting the arbitral tribunal enjoin the Company from interfering in POSCO Energy’s exclusive rights under the License Agreements and (z) seeking an order that the Company pay POSCO Energy’s arbitration costs, including counsel fees and expenses. The Company has discontinued revenue recognition of the deferred license revenue related to the terminated POSCO Energy License Agreements given the pending arbitration and will continue to evaluate this deferred revenue in future periods. On August 28, 2020, POSCO Energy filed a complaint in the Court of Chancery of the State of Delaware (the “Court”) purportedly seeking to enforce its rights as a stockholder of the Company to inspect and make copies and extracts of certain books and records of the Company and/or the Company’s subsidiaries pursuant to Section 220 of the Delaware General Corporation Law and/or Delaware common law. POSCO Energy alleges that it is seeking to inspect these documents for a proper purpose reasonably related to its interests as a stockholder of the Company, including investigating whether the Company’s Board of Directors and its management breached their fiduciary duties of loyalty, due care, and good faith. POSCO Energy seeks an order of the Court permitting POSCO Energy to inspect and copy the demanded books and records, awarding POSCO Energy reasonable costs and expenses, including reasonable attorney’s fees incurred in connection with the matter, and granting such other and further relief as the Court deems just and proper. On September 14, 2020, POSCO Energy filed a complaint in the United States District Court for the Southern District of New York alleging that the Company delayed the removal of restrictive legends on certain share certificates held by POSCO Energy in 2018, thus precluding POSCO Energy from selling the shares and resulting in claimed losses in excess of $1,000,000. The Company does not believe that any of the arbitrations or legal proceedings brought against the Company by POSCO Energy are for a proper purpose. Further, the Company believes that all such arbitrations and legal proceedings are in fact simply fulfillment of POSCO Energy’s prior threats to file a series of actions against the Company and are attempts to obtain leverage over the Company and, in certain proceedings, gain advantage in the pending arbitration filed by the Company against POSCO Energy. The Company will vigorously defend itself against POSCO Energy’s claims in all forums and believes it will be apparent at the conclusion of each matter that each action was filed for an improper purpose. Other Legal Proceedings From time to time, the Company is involved in other legal proceedings, including, but not limited to, regulatory proceedings, claims, mediations, arbitrations and litigation, arising out of the ordinary course of its business (“Other Legal Proceedings”). Although the Company cannot assure the outcome of such Other Legal Proceedings, management presently believes that the result of such Other Legal Proceedings, either individually, or in the aggregate, will not have a material adverse effect on the Company’s consolidated financial statements, and no material amounts have been accrued in the Company’s consolidated financial statements with respect to these matters. Impact of the COVID-19 Pandemic On March 18, 2020, in response to the COVID-19 pandemic, we temporarily suspended operations at our Torrington, Connecticut manufacturing facility and also ordered those employees that could work from home to do so. The Company resumed operations in the manufacturing facility on June 22, 2020. All employees that were not able to work from home due to their job function during the manufacturing facility shutdown received full wages and benefits during such time. We did not implement any furlough, layoff or shared work program during such time. The Company continues to encourage a remote work protocol for portions of the workforce due to the continuing pandemic. We continue to evaluate our ability to operate in light of recent resurgences of COVID-19 and the advisability of continuing operations based on federal, state and local guidance, evolving data concerning the pandemic and the best interests of our employees, customers and stockholders. While we have attempted to continue business development activities during the pandemic, state and local shut downs, shelter in place orders and travel restrictions have impeded our ability to meet with customers and solicit new business, and certain bids and solicitations in which we typically participate have been postponed. We expect these impacts to continue until such shut downs, shelter in place orders and travel restrictions are fully lifted and bids and solicitations are allowed to proceed. We have not experienced any material impacts to our supply chain, construction or service activities to date.

We did not seek a waiver under Regulation Crowdfunding as we do not expect to rely on crowdfunding in raising capital.

On March 18, 2020, in response to the COVID-19 pandemic, we temporarily suspended operations at our Torrington, Connecticut manufacturing facility and also ordered those employees that could work from home to do so. The Company resumed operations in the manufacturing facility on June 22, 2020.
