FORM 8-K
Earnings Release Classification · 95% confidence The document is a Form 8-K Current Report filed with the SEC, dated January 24, 2024. It announces the financial results for the third quarter ended December 31, 2023, and includes a press release as an exhibit. The text explicitly states that the press release is attached and is a furnished item, not filed, and that the information is not deemed filed for certain regulatory purposes. The document is short (3830 characters) and primarily serves as an announcement of the earnings release rather than the full earnings report itself. According to the rules, such announcements with attached press releases are classified as Earnings Release (ER).

FORM 8-K
Earnings Release Classification · 95% confidence The document is a Form 8-K Current Report filed with the SEC, dated November 1, 2023. It announces the financial results for the second quarter ended September 30, 2023, but the actual financial results are contained in an attached press release (Exhibit 99.1). The text explicitly states that the press release is "furnished, not filed," and the document itself is a brief announcement rather than a full financial report. The document length is 3824 characters, which is relatively short and consistent with an announcement rather than a full earnings release. According to the rules, such a document announcing financial results with an attached press release but not containing substantive financial data itself should be classified as an Earnings Release (ER) if it contains key highlights, or Regulatory Filings (RNS) if it is just a filing of the press release. Since the press release is attached as an exhibit and the 8-K is announcing the results, this is best classified as an Earnings Release (ER).

FORM 8-K
Declaration of Voting Results & Voting Rights Announcements Classification · 100% confidence The document is a Form 8-K filed with the SEC, dated August 11, 2023, reporting the submission of matters to a vote of security holders at the company's Annual Meeting. It details the voting results on director elections, ratification of the independent auditor, and advisory votes on executive compensation frequency. The content focuses on official results from shareholder votes at a general meeting. The document length is 5386 characters, which is sufficient to contain detailed voting results rather than just an announcement of a report. Therefore, this filing fits the category of Declaration of Voting Results & Voting Rights Announcements (DVA).
