Basis of Presentation	1. Basis of Presentation Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements of Tsakos Energy Navigation Limited (the “Holding Company”) and subsidiaries (collectively, the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 6-K and Article 10 of Regulation S-X of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for fair presentation have been included. Operating results for the six months ended June 30, 2022, are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. The consolidated balance sheet as of December 31, 2021, has been derived from the audited consolidated financial statements included in the Company’s annual report on Form 20-F filed with the SEC on April 28, 2022 (“Annual Report”), but does not include all of the footnotes required by U.S. GAAP for complete financial statements. *Impact of COVID-19 on the Company’s Business* The spread of the COVID-19 virus, which has been declared a pandemic by the World Health Organization, in 2020 has caused substantial disruptions in the global economy and the shipping industry, as well as significant volatility in the financial markets, the severity and duration of which remains uncertain. The impact of the COVID-19 pandemic continues to unfold and it may continue to negatively affect the global economy and demand for oil which may have a negative effect on the Company’s business, financial performance and the results of its operations, including due to any renewed weakness in demand for seaborne transportation of oil and oil products and LNG, and in turn charter rates, the extent of which will depend largely on future developments. As a result, many of the Company’s estimates and assumptions required increased judgment and carry a higher degree of variability and volatility. As events continue to evolve and additional information becomes available, the Company’s estimates may change in future periods. *Impact of the War in Ukraine on the Company’s Business* As a result of the ongoing conflict between Russia and Ukraine which commenced in February 2022, the US, the EU, the UK and others have announced unprecedented levels of sanctions and other measures against Russia and certain Russian entities and nationals. The Company intends on complying with these requirements and addressing their potential consequences. The conflict in Ukraine, and the economic sanctions imposed by the EU, U.S. and other countries in response to Russian action, is disrupting energy production and trade patterns, including shipping in the Black Sea and elsewhere, and its impact on energy prices and tanker rates, which initially have increased, is uncertain. The extent to which this will impact the Company’s future results of operations and financial condition will depend on future developments, which are highly uncertain and cannot be predicted. Accordingly, an estimate of the impact cannot be made at this time. *Significant Accounting Policies* A discussion of the Company’s significant accounting policies can be found in Note 1 of the Company’s consolidated financial statements included in the Annual Report. There have been no material changes to these policies in the six-month period ended June 30, 2022, except as discussed below: Accounting for Leases: Sale and Leaseback transactions: In accordance with ASC 842, the Company, as seller-lessee, determines whether the transfer of an asset should be accounted for as a sale in accordance with ASC 606. The existence of an option for the seller-lessee to repurchase the asset precludes the accounting for the transfer of the asset as a sale unless both of the following criteria are met: (1) the exercise price of the option is the fair value of the asset at the time the option is exercised and (2) there are alternative assets, substantially the same as the transferred asset, readily available in the marketplace; and the classification of the leaseback as a finance lease or a sales-type lease, precludes the buyer-lessor from obtaining control of the asset. The existence of an obligation for the Company, as seller-lessee, to repurchase the asset precludes accounting for the transfer of the asset as sale as the transaction would be classified as a financing arrangement by the Company as it effectively retains control of the underlying asset. If the transfer of the asset meets the criteria of sale, the Company, as seller-lessee recognizes the transaction price for the sale when the buyer-lessor obtains control of the asset, derecognizes the carrying amount of the underlying asset and accounts for the lease in accordance with ASC 842. If the transfer does not meet the criteria of sale, the Company does not derecognize the transferred asset, accounts for any amounts received as a financing arrangement and recognizes the difference between the amount of consideration received and the amount of consideration to be paid as interest. The Company has entered into one sale and lease back transactions accounted for as a financing arrangement as of June 30, 2022 (Note 6). *New Accounting Pronouncements—Not Yet Adopted:* In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope. The ASU clarifies that all derivative instruments affected by changes to the interest rates used for discounting, margining or contract price alignment due to reference rate reform are in the scope of ASC 848. As such, entities may apply certain optional expedients in ASC 848 to derivative instruments that do not reference LIBOR, or another rate expected to be discontinued as a result of reference rate reform if there is a change to the interest rate used for discounting, margining or contract price alignment. In addition, the ASU clarifies other aspects of the guidance in ASC 848 and provides new guidance on how to address the effects of the cash compensation adjustment that is provided as part of the above change on, certain aspects of hedge accounting. The ASU is effective for all entities as of January 7, 2021, allows for retrospective or prospective application with certain conditions, and generally can be applied through December 31, 2022. The Company has not adopted the ASU as of June 30, 2022. The Company is currently evaluating the impact this guidance may have on its consolidated financial statements and related disclosures.
