UPDATED NOTE C - TYPOGRAPHICAL ERROR
Annual Report Classification · 95% confidence The document is a Form 11-K/A, which is an annual report filed pursuant to Section 15(d) of the Securities Exchange Act of 1934. It specifically relates to The MasTec, Inc. 401(k) Retirement Plan and includes audited financial statements, notes to financial statements, and schedules for the years ended December 31, 2003 and 2002. The presence of detailed financial statements, auditor's report, and notes confirms this is a full annual report for an employee benefit plan, not just an announcement or certification. Therefore, the document fits the category of an Annual Report (10-K) type filing for employee benefit plans, which is consistent with SEC Form 11-K filings. The document length (15,000 characters) and content confirm it is the report itself, not just an announcement or certification.

ANNUAL REPORT-FISCAL YEAR ENDED DECEMBER 31, 2003
Annual Report Classification · 95% confidence The document is titled 'FORM 11-K' and is an annual report for the fiscal year ended December 31, 2003, specifically for The MasTec, Inc. 401(k) Retirement Plan. It includes detailed financial statements such as statements of net assets available for benefits, statement of changes in net assets, notes to financial statements, and an auditor's report. The 11-K form is a specific annual report filed with the SEC for employee benefit plans, which is distinct from the standard 10-K annual report for companies. The document contains substantive financial data and analysis, not just an announcement or certification. Therefore, it should be classified as an Annual Report (10-K) type filing, as 11-K is a type of annual report for employee benefit plans under SEC rules.
