Good morning. Thank you, April. Good morning, everyone, and welcome to American Superconductor Corporation's Fourth Quarter and Fiscal Year 2020 Earnings Conference Call. I am John Heilshorn of LHA Investor Relations, AMSC's Investor Relations agency of record. With us today on the call are Daniel McGahn, Chairman, President and Chief Executive Officer; and John Kosiba, Senior Vice President, Chief Financial Officer and Treasurer. American Superconductor issued its earnings release for the fourth quarter and full fiscal year 2020 yesterday after the market closed. For those of you who have not yet seen the release, a copy is available in the Investors page of the company's website at www.amsc.com.
Before starting the call, I would like to remind you that various remarks that management may make during today's call about American Superconductor's future expectations, plans and prospects constitute forward-looking statements for purposes of the safe harbor provisions under the Private Securities Litigation Reform Act of 1995. Actual results may differ materially from those indicated by such forward-looking statements as a result of various important factors including those set forth in the Risk Factors section of American Superconductor's annual report on Form 10-K for the year ended March 31, 2021, which the company filed with the Securities and Exchange Commission on June 2, 2021, and the company's other reports filed with the Securities and Exchange Commission.
These forward-looking statements represent management's expectations only as of today and should not be relied upon as representing management's views as of any subsequent date to today. While the company anticipates that subsequent events and developments may cause the company's views to change, the company specifically disclaims any obligation to update these forward-looking statements.
Also, on today's call, management will refer to certain non-GAAP financial measures, non-GAAP net loss and non-GAAP operating cash flow. Non-GAAP net loss is defined by the company as net loss before stock-based compensation, amortization of acquisition-related intangibles, acquisition costs, changes in fair value of contingent consideration of warrants and other noncash or unusual charges and the tax effect of the adjustments calculated at the relevant rate for the company's non-GAAP metric.
Non-GAAP operating cash flow is defined by the company as operating cash flow before the China settlement, net of legal fees and expenses, tax effect of adjustments and other unusual cash flows or items. The reconciliation of the non-GAAP measures to the mostly directly comparable GAAP measures can be found in the fourth quarter and full fiscal year 2020 earnings press release that the company issued and furnished to the SEC last night on Form 8-K. All of American Superconductor's press releases and SEC filings can be accessed from the Investors page of its website at www.amsc.com.
With that, I will now turn the call over to Chairman, President and Chief Executive Officer, Daniel McGahn. Daniel?
