Form 8-K

Form 8-K is the current report a company files with the SEC when one of the events the form lists occurs. Rule 13a-11 requires every registrant subject to Rule 13a-1 to "file a current report on Form 8-K within the period specified in that form." General Instruction B says a report is required "upon the occurrence of any one or more of the events specified in the items" of the form and, unless an item says otherwise, "within four business days after occurrence of the event." Changes among a company's senior officers, the principal financial officer included, are reported under Item 5.02. The moves on CFO Tribune are read from these filings.
