Annual Report Classification · 95% confidence The document is titled 'FORM 11-K' and is an annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934 for the fiscal year ended December 31, 2017. It contains detailed financial statements and schedules for the Alliant Energy Corporation 401(k) Savings Plan, including statements of net assets, changes in net assets, notes to financial statements, and an independent auditor's report. The content is comprehensive and includes actual financial data and analysis, not just an announcement or certification. Therefore, it fits the definition of an Annual Report specific to employee benefit plans, which is filed on Form 11-K with the SEC. Given the specificity of the form and the detailed financial content, the appropriate classification is Annual Report (10-K) category, as 11-K is a type of annual report for employee benefit plans under SEC rules.

8-K
Capital/Financing Update Classification · 95% confidence The document is a Form 8-K current report filed with the SEC, dated June 6, 2018, reporting the issuance of senior notes (debt financing) by Alliant Energy Finance, LLC, a subsidiary of Alliant Energy Corporation. The content focuses on the details of the debt issuance, terms of the notes, use of proceeds, and related agreements. There are no financial statements or comprehensive financial data presented, only a description of a financing transaction. This fits the definition of a Capital/Financing Update (CAP) filing, which covers updates on company fundraising and capital structure changes. The document length is 7,752 characters, which is substantive and not a mere announcement or certification. Therefore, the appropriate classification is CAP with high confidence.

Declaration of Voting Results & Voting Rights Announcements Classification · 100% confidence The document is a Form 8-K filing with the SEC, dated May 17, 2018, reporting the final results of voting on matters submitted to shareholders at the annual meeting of Alliant Energy Corporation and a written consent for Interstate Power and Light Company. The content focuses on election of directors, advisory votes on executive compensation, ratification of auditors, and shareholder proposals. This matches the description of Declaration of Voting Results & Voting Rights Announcements (DVA). The document is about voting results, not the full annual report or other types of filings. The length is about 4987 characters, which is consistent with a detailed voting results announcement rather than a full report. Therefore, the correct classification is DVA with high confidence.

8-K
Capital/Financing Update 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 content describes the entry into a material definitive agreement for a distribution agreement related to the sale of common stock up to $175 million. It includes details about the agreement, the agents involved, and the intended use of proceeds. There are no financial statements or comprehensive financial data presented, nor is this an earnings release or annual/interim report. The document is not a proxy, voting result, or management change announcement. It is clearly an update on capital raising activities through a distribution agreement. Therefore, the most appropriate classification is Capital/Financing Update (CAP). The document length is sufficient and contains substantive information about the financing event, not just an announcement of a report, so it is not RPA or RNS. Confidence is high due to clear identification of the filing type and content.
