8-K
Board/Management Information Classification · 95% confidence The document is a Form 8-K filed with the SEC, dated June 13, 2018, by American Superconductor Corporation. The key content is under Item 5.02, which reports the departure of a director from the Board of Directors. There is no financial data, earnings information, or report publication mentioned. The document specifically announces a change in the company's board membership. According to the filing definitions, announcements of changes in the company's board of directors or senior management fall under Board/Management Information (MANG). The document length is 3080 characters, which is relatively short but contains substantive information about management changes, not just a notice or announcement of a report. Therefore, the correct classification is MANG with high confidence.

8-K
Regulatory Filings Classification · 95% confidence The document is a Form 8-K current report filed with the SEC, dated June 6, 2018, by American Superconductor Corporation. It announces the company's financial results for the fourth quarter and full fiscal year ended March 31, 2018, but the actual financial results are contained in an attached press release (Exhibit 99.1). The document explicitly states that the press release is "furnished, not filed," and the 8-K itself is a brief announcement rather than a full financial report. The document length is 3631 characters, which is relatively short and consistent with an announcement rather than a full earnings release or annual report. According to the rules, such a document is best classified as a Regulatory Filing (RNS) because it is a general regulatory announcement and does not contain substantive financial data itself, only a reference to the press release. It is not an Earnings Release (ER) because it does not contain the financial highlights directly, only a notice of their release.
