FORM 11-K
Annual Report Classification · 100% 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, including statements of net assets available for benefits, changes in net assets, notes to financial statements, and an independent auditor's report. The content is comprehensive and includes substantive financial data and analysis related to the Savings Plan for the Employees of NewMarket Corporation and Affiliates. The presence of the auditor's opinion and detailed financial schedules confirms this is the actual report, not just an announcement or certification. Therefore, the document fits the definition of an Annual Report (10-K) type filing, specifically the 11-K form which is an annual report for employee benefit plans filed with the SEC.

SD
Regulatory Filings Classification · 95% confidence The document is a Form SD filed with the SEC, titled 'Specialized Disclosure Report' for NewMarket Corporation. It specifically addresses conflict minerals disclosure pursuant to Rule 13p-1 under the Securities Exchange Act for the reporting period January 1 to December 31, 2017. The content focuses on conflict minerals sourcing and compliance, not on financial results, management changes, or other report types. Form SD is a specialized regulatory filing for conflict minerals disclosure and does not fall under annual reports, earnings releases, or other categories. Given the nature and regulatory context, this document fits best under Regulatory Filings (RNS). The document length is moderate and contains detailed disclosure, not just an announcement or certification, so it is not RPA or a certification-only filing.

FORM 8-K
Board/Management Information Classification · 95% confidence The document is a Form 8-K filed with the SEC, dated May 15, 2018, reporting the appointment of a new President for a subsidiary company and changes in officer roles. The key section is Item 5.02, which relates to the departure and appointment of directors or certain officers. The document includes a press release as an exhibit. There are no financial statements or detailed financial data presented. The content focuses on management changes rather than financial results or other report types. According to the filing definitions, announcements of changes in the company's board of directors or senior management fall under Board/Management Information (MANG). The document length is 3484 characters, which is relatively short and consistent with a management change announcement. Therefore, the appropriate classification is MANG with high confidence.
