Filing Released Lang Actions
FORM 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 related to a distribution agreement for selling common stock. It includes details about the agreement, the parties involved, and legal opinions. There are no financial statements or comprehensive financial data presented, nor is this an annual or quarterly report. The document is an announcement of a capital raising arrangement and related agreements, which fits the category of Capital/Financing Update (CAP). The document length is 6764 characters, which is sufficient to contain substantive information about the financing event rather than just a brief announcement or a report publication notice. Therefore, the appropriate classification is CAP with high confidence.

424B5
Capital/Financing Update Classification · 95% confidence The document is a prospectus supplement and accompanying prospectus related to a securities offering by Alliant Energy Corporation. It includes details about a common stock offering, registration fee calculations under Rule 424(b)(5), distribution agreements with agents, risk factors, use of proceeds, and legal matters. The document is a formal offering document filed with the SEC, describing terms of a capital raise through common stock issuance. This fits the definition of a Capital/Financing Update (CAP), which covers updates on company fundraising and financing activities. The document is not an annual report, earnings release, or other report type, but specifically a prospectus supplement for a stock offering. The length and content confirm it is the actual offering document, not just an announcement of a report. Therefore, the correct classification is CAP with high confidence.
2017-05-09 English
DEFA14A
Proxy Solicitation & Information Statement Classification · 95% confidence The document is a Schedule 14A filing, which is a proxy statement or related materials filed with the SEC. It references the upcoming Annual Meeting and encourages voting on various proposals, including board elections and a shareholder proposal. The document is titled 'Definitive Additional Materials' related to the proxy statement, which typically supplements the main proxy statement with additional information or reminders. It is not the proxy statement itself, nor is it a report like an annual report or earnings release. The content focuses on proxy solicitation and voting information for shareholders. Therefore, the document fits best under Proxy Solicitation & Information Statement (PSI). The document length is under 5,000 characters, but it contains substantive solicitation content rather than just an announcement of a report publication, so it is not RPA or RNS.
2017-05-08 English
10-Q
Interim / Quarterly Report Q1 2017
2017-05-04 English
8-K
Regulatory Filings Classification · 95% confidence The document is a Form 8-K Current Report filed with the SEC, dated May 3, 2017. It announces the issuance of a press release regarding financial results for the quarter ended March 31, 2017. The document itself does not contain detailed financial statements or substantive financial data but rather references the press release as an exhibit. The length is 3854 characters, which is relatively short and consistent with an announcement rather than a full report. According to the 'Menu vs Meal' rule, this is an announcement of financial results, not the full earnings release or quarterly report itself. Therefore, the appropriate classification is Regulatory Filings (RNS), which is the fallback for such SEC filings that do not fit other categories and are announcements or certifications.
2017-05-03 English
DEFA14A
Proxy Solicitation & Information Statement Classification · 100% confidence The document is titled 'SUPPLEMENT TO PROXY STATEMENT DATED APRIL 18, 2017' and references corrections to the Proxy Statement related to the 2017 Annual Meeting of Shareowners. It is a supplement providing additional or corrected information to a previously filed Proxy Statement. The document is short (3117 characters) and does not contain financial statements or detailed executive compensation data itself, but rather amends the Proxy Statement. Proxy Statements and their supplements fall under the category of Proxy Solicitation & Information Statement filings. The form type DEFA14A confirms it is a definitive additional proxy material filing. Therefore, the correct classification is Proxy Solicitation & Information Statement (PSI).
