Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	NOTE A - BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements of Odyssey Marine Exploration, Inc. and subsidiaries (the “Company,” “Odyssey,” “us,” “we” or “our”) have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission and the instructions to Form 10-Q and, therefore, do not include all information and footnotes normally included in financial statements prepared in accordance with generally accepted accounting principles. These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. In the opinion of management, these financial statements reflect all adjustments, including normal recurring adjustments, necessary for a fair presentation of the financial position as of March 31, 2017 and the results of operations and cash flows for the interim period presented. Operating results for the three-month period ended March 31, 2017 are not necessarily indicative of the results that may be expected for the full year. Recent accounting pronouncements In May 2014, the Financial Accounting Standards Board, or the FASB, issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers, or ASU 2014-09, which establishes a comprehensive revenue recognition standard under GAAP for almost all industries. The new standard will apply for annual periods beginning after December 15, 2017, including interim periods therein. Early adoption is prohibited. Based on management’s review of this new standard along with the substance of our transactions, management is of the position this standard will not have a material impact on our financial statements. In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases, which establishes a comprehensive lease standard under GAAP for virtually all industries. The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease. A lessee is also required to record a right of use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales type leases, direct financing leases and operating leases. The new standard will apply for annual periods beginning after December 15, 2018, including interim periods therein, and requires modified retrospective application. Early adoption is permitted. Based on management’s current understanding of this new standard along with the underlying substance of our operations, management believes it will not have a material impact on our financial statements. Other recent accounting pronouncements issued by the FASB, the AICPA and the SEC did not or are not believed by management to have a material effect, if any, on the Company’s financial statements.
