8-K Filing
M&A Activity Classification · 100% confidence The document is a Form 8-K filed with the SEC, dated August 5, 2011, reporting the completion of an acquisition of assets from Bank of Whitman by Columbia State Bank. It includes details about the acquisition terms, assets and deposits acquired, and references a purchase and assumption agreement. The document also mentions a press release announcing the acquisition. There are no financial statements or detailed financial data included in this filing; it is primarily an announcement of a corporate transaction (acquisition). This fits the category of a Current Report on Form 8-K related to M&A activity. Therefore, the appropriate classification is M&A Activity (TAR). The document length is 4661 characters, which is sufficient to contain substantive information about the transaction, not just a brief announcement or a report publication notice.

8-K/A Filing
Regulatory Filings Classification · 95% confidence The document is a Form 8-K/A (Amendment No. 1) filed with the SEC, which is a Current Report pursuant to the Securities Exchange Act of 1934. It reports the acquisition of certain assets and liabilities of First Heritage Bank by Columbia Banking System, Inc. from the FDIC. The document provides detailed financial information about the acquisition, including fair values of assets and liabilities, loss sharing agreements, and financial statements of the acquired business. The document is not an Annual Report (10-K), Interim Report (10-Q), or Earnings Release, but a current report on a significant event (acquisition). It is not a simple announcement or certification but contains substantive financial data related to the acquisition. Therefore, it fits best under the category of Regulatory Filings (RNS) as a current report on a material event that does not fall into other specific categories like M&A filings or Audit Reports. The document is detailed and lengthy (15,000 characters), indicating it is not a mere announcement but a full current report amendment.

8-K/A Filing
Regulatory Filings Classification · 95% confidence The document is a Form 8-K/A (Amendment No. 1) filed with the SEC by Columbia Banking System, Inc. It reports the acquisition of certain assets and liabilities of Summit Bank from the FDIC, including detailed financial information about the acquisition such as fair values of assets and liabilities, loss sharing agreements, and financial statements of the acquired business. The document includes extensive financial data and discussion related to the acquisition, which is a significant event but not a full annual or quarterly report. The filing is a current report amendment providing detailed financial disclosures about a specific transaction, consistent with the purpose of Form 8-K filings. This type of filing is best classified under Regulatory Filings (RNS) because it is a current report amendment disclosing a material event and related financial information, not a full annual report, interim report, or other specific report type. The document length and detail confirm it is not a brief announcement or certification but a substantive regulatory filing.
