Amendment Description
EXPLANATORY NOTE
GulfSlope Energy, Inc. (the "Company," "we," or "our" unless the context indicates otherwise) is filing this Amendment No. 1 on Form 10-K/A (this "Amendment") to our Annual Report on Form 10-K for the fiscal year ended September 30, 2012, as filed on December 31, 2012 (the "Original Filing") to correct the comparative balance sheet information for the fiscal year ended September 30, 2011 to reflect the correct par value of the Company's common stock and additional paid in capital. This correction resulted in a decrease to common stock with an offsetting increase to additional paid in capital for the presentation of these equity accounts within the fiscal year ended September 30, 2011 balance sheet only. No change was required for total equity on the balance sheet for the fiscal year ended September 30, 2011, or to any other financial statement or disclosure. This Amendment on Form 10-K/A only amends the Original Filing as noted above. This Amendment does not affect any other parts of or exhibits to the Original Filing, and no other information in the Original Filing, including the fiscal year ended September 30, 2011 statement of stockholders' equity or related notes to the financial statements, are amended hereby. Except for the amendments described above, this Amendment on Form 10-K/A continues to describe conditions as of the date of the Original Filing, and the disclosures contained herein have not been updated to reflect events, results or developments that occurred after the Original Filing, or to modify or update those disclosures affected by subsequent events. Among other things, forward-looking statements made in the Original Filing have not been revised to reflect events, results or developments that occurred or facts that became known to us after the date of the Original Filing, and such forward-looking statements should be read in their historical context. Additionally, in connection with the filing of this Form 10-K/A and pursuant to Securities and Exchange Commission ("SEC") rules, we are including currently dated certifications. For convenience, the entire Annual Report on Form 10-K, as amended, is being re-filed.
