8-K Filing
Transaction in Own Shares Classification · 100% confidence The document is a Form 8-K filed with the SEC, dated January 29, 2026. It announces the authorization of a share repurchase program by the company's Board of Directors, including details about the Federal Reserve's nonobjection and the terms of the repurchase program. The document does not contain financial statements or detailed financial results but is an announcement of a capital action related to the company's shares. This fits the category of a Transaction in Own Shares (POS), which covers share repurchase announcements. The document length is 4024 characters, which is consistent with a typical 8-K announcement rather than a full financial report.

8-K Filing
Regulatory Filings Classification · 95% confidence The document is a Form 8-K filed with the SEC, which is a current report used to announce major events that shareholders should know about. The text specifically mentions Item 2.02 "Results of Operations and Financial Condition" and states that the company issued a press release announcing its financial results for the fourth quarter ended December 31, 2025. The document includes exhibits such as the press release and loan portfolio disclosures. The length of the document is 3505 characters, which is relatively short and consistent with a current report rather than a full financial report. The Form 8-K is not a full Annual Report (10-K) or Interim Report (10-Q/IR), but rather a current report announcing financial results and other material events. Therefore, the appropriate classification is Regulatory Filings (RNS), as it is a general regulatory announcement and does not contain the full financial statements or detailed analysis required for other report types.

8-K Filing
Notice of Dividend Amount Classification · 95% confidence The document is a Form 8-K filed with the SEC, which is a current report used to announce major events. The key content is the declaration of a cash dividend by the Board of Directors, specifying the dividend amount, payment date, and record date. The document length is short (2850 characters), and it primarily announces the dividend amount and payment details. This matches the definition of a Notice of Dividend Amount (DIV) filing, which announces dividend amounts and payment dates to shareholders. There is no detailed financial data or other report content, so it is not an Annual Report or Earnings Release. Therefore, the correct classification is DIV with high confidence.
