Form 10-K405

U.S. SEC filing used to indicate lack of insider trading disclosure Form 10-K405 is an SEC filing to the US Securities and Exchange Commission (SEC) that indicates that an officer or director of a public company failed to file a Form 4 (or related Form 3 or Form 5) on time, in violation of Section 16 - meaning that they did not disclose their insider trading activities within the required time period. Prior to 2003, 10-K forms submitted to the SEC contained the following qualifier: Indicate by check mark if disclosure of delinquent filers pursuant to Item 405 of Regulation S-K is not contained herein, and will not be contained to the best of registrant's knowledge in definitive proxy or information statements incorporated by reference in Part III of this Form 10-K or any amendment to this Form 10-K. [X] If this box is checked on the form, the SEC asks that it be filed as a 10-K405. Otherwise the form is filed as a 10-K. Other than the checkbox, the SEC indicates there is no difference in substance between the two forms. For the years where electronic filing has been required, almost one-third of the filings are registered as a 10-K405. This classification was discontinued after 200
