The following list of submission types are the most common filing types used by EDGAR filers:

Form Type	Description
3	Initial statement, which identifies holdings of registrant’s securities owned by directors, officers and 10% shareholders. A Form 3 must be filed within 2 business days after the event. An insider of an issuer that is registering equity securities for the first time under section 12 of the Exchange Act must file this form no later than the effective date of the registration statement. If the issuer already registered under Section 12, the insider must file within ten days of becoming an officer, director or beneficial owner.

6-K	This report is used by certain foreign private issuers to furnish information: (i) required to be made public in the country of its domicile; (ii) filed with and made public by a foreign stock exchange on which its securities are traded; or (iii) distributed to security holders. The report must be furnished promptly after such material is made public. The form is not considered “filed’’ for Section 18 liability purposes. This is the only information furnished by foreign private issuers between annual reports, since such issuers are not required to file on Form 10-Q or 8-K.
8-A	This form is used by 1934 Act registrants wishing to register additional securities or classes thereof.
8-K	This is the “current report” that is used to report the occurrence of any material events or corporate changes which are of importance to investors or security holders and previously have not been reported by the registrant. It provides more current information on certain specified events than would Form 10-Q or 10-K. An insider of an issuer that is registering equity securities for the first time under Section 12 of the Exchange Act must file this form no later than the effective date of the Registration Statement. If the issuer is already registered under Section 12, the insider must file Form 3 within ten days of becoming an officer, director or beneficial owner.
10-K	This is the annual report that most reporting companies file with the Commission. It provides a comprehensive overview of the registrant’s business.

10-Q	The Form 10-Q is a report filed quarterly by most reporting companies. It includes unaudited financial statements and provides a continuing view of the company’s financial position during the year. The report must be filed for each of the first three fiscal quarters of the company’s fiscal year and is due within 45 days of the close of the quarter. Accelerated filers will file in 40 days the first year, and then 35 days thereafter.
11-K	This form is a special annual report for employee stock purchase, savings, and similar plans, interests in which constitute securities registered under the 1933 Act. The Form 11-K annual report is required in addition to any other annual report of the issuer of the securities.
