8-K
Regulatory Filings Classification · 95% confidence The document is a Form 8-K current report filed with the SEC reporting Item 4.01 (Change in Registrant’s Certifying Accountant), which is a routine regulatory disclosure rather than a full audit report, financial statements, proxy materials, or management discussion. It does not present complete financial results or strategy, but is a compliance filing notifying the SEC (and investors) of the change in independent auditor. Thus it falls under the fallback category for miscellaneous regulatory filings.

Report Publication Announcement Classification · 90% confidence The document is a Form 8-K that merely announces the publication of a press release with first quarter results (Exhibit 99.1) but does not itself include any financial data. It is under 5,000 characters and explicitly states the report is furnished as an exhibit. Under the “menu vs. meal” rule, this constitutes an announcement of a report’s publication rather than the actual earnings release or a full report, so it should be classified as a Report Publication Announcement (RPA).
