There remains continuing uncertainty regarding the length and severity of the impact of COVID-19 on the economy, in general, and the energy industry, in particular, each of which has a significant effect on the outlook for the Company’s business. The decrease in oil and natural gas prices experienced at the beginning stages of the COVID-19 pandemic led to a decrease in the demand for the Company’s products and services. Although the underlying commodity prices supporting such demand have recovered substantially, the risk of continued volatility in the commodity prices remains.

Control is generally deemed to exist if the Company has greater than 50% of the voting rights of a subsidiary. All significant intercompany accounts and transactions are eliminated in the combination and consolidation.</span></p> <p style="text-align:justify;margin-bottom:0pt;margin-top:10pt;text-indent:6.67%;font-size:12pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Noncontrolling interests in consolidated subsidiaries are included in the consolidated balance sheets as a separate component of equity. The Company reports consolidated net income (loss) inclusive of both the Company’s and the noncontrolling interests’ share, as well as the amounts of consolidated net income (loss) attributable to each of the Company and the noncontrolling interests. If a subsidiary is deconsolidated upon a change in control, any retained noncontrolling equity investment in the former controlled subsidiary is measured at fair value and a gain or loss is recognized in net income (loss) based on such fair value. If a subsidiary is consolidated upon the acquisition of controlling interests by the Company, any previous noncontrolled equity investment in the subsidiary is measured at fair value and a gain or loss is recognized in net income (loss) based on such fair value.</p> <p style="text-align:justify;margin-bottom:0pt;margin-top:10pt;text-indent:6.67%;font-size:12pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The Company employs the equity method of accounting for investments in 50% or less owned companies that it does not control but has the ability to exercise significant influence over the operating and financial policies of the business venture. Significant influence is generally deemed to exist if the Company has between 20% and 50% of the voting rights of a business venture but may exist when the Company’s ownership percentage is less than 20%. In certain circumstances, the Company may have an economic interest in excess of 50% but may not control and consolidate the business venture. Conversely, the Company may have an economic interest less than 50% but may control and consolidate the business venture. The Company reports its investments in and advances to these business ventures in the accompanying consolidated balance sheets as investments, at equity, and advances to 50% or less owned companies. The Company reports its share of earnings from investments in 50% or less owned companies in the accompanying consolidated statements of net income (loss) as equity in earnings (losses) of 50% or less owned companies, net of tax.</p> <p style="text-align:justify;margin-bottom:0pt;margin-top:10pt;text-indent:6.67%;font-size:12pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Certain reclassifications were made to previously reported amounts in the consolidated financial statements and notes thereto to make them consistent with the current period presentation.</p> <p style="text-align:justify;margin-bottom:0pt;margin-top:10pt;text-indent:6.67%;font-weight:bold;font-style:italic;font-size:12pt;font-family:Times New Roman;text-transform:none;font-variant: normal;">Use of Estimates.<span style="font-weight:normal;font-style:normal;"> The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates include those related to deferred revenues, allowance for credit loss accounts, useful lives of property and equipment, impairments, income tax provisions and certain accrued liabilities. Actual results could differ from estimates and those differences may be material.</span></p> <p style="text-align:justify;margin-bottom:0pt;margin-top:10pt;text-indent:6.67%;font-weight:bold;font-style:italic;font-size:12pt;font-family:Times New Roman;text-transform:none;font-variant: normal;">Revenue Recognition<span style="font-weight:normal;font-style:normal;">. Revenue is recognized when (or as) the Company transfers promised goods or services to its customers in amounts that reflect the consideration to which the Company expects to be entitled to in exchange for those goods or services, which occurs when (or as) the Company satisfies its contractual obligations and transfers over control of the promised goods or services to its customers. The Company recognizes revenue net of sales taxes based on its estimates of the consideration the Company expects to receive. Costs to obtain or fulfill a contract are expensed as incurred.</span></p> <p style="text-align:justify;margin-bottom:0pt;margin-top:10pt;text-indent:6.67%;font-size:12pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The Company earns revenue primarily from the time charter and bareboat charter of vessels to customers. Since the Company charges customers based upon daily rates of hire, vessel revenues are recognized on a daily basis throughout the contract period. Under a time charter, the Company provides a vessel to a customer and is responsible for all operating expenses, typically excluding fuel. Under a bareboat charter, the Company provides a vessel to a customer and the customer assumes responsibility for all operating expenses and assumes all risks of operation. In the U.S. Gulf of Mexico, time charter durations and rates are typically established in the context of master service agreements that govern the terms and conditions of the charter.</p> <p style="text-align:justify;margin-bottom:0pt;margin-top:10pt;text-indent:6.67%;font-size:12pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Contract or charter durations may range from several days to several years. Charters vary in length from short-term to multi-year periods, many with cancellation clauses and without early termination penalties. As a result of options and frequent renewals, the stated duration of charters may have little correlation with the length of time the vessel is contracted to provide services to a particular customer.</p> <p style="text-align:justify;margin-bottom:0pt;margin-top:10pt;text-indent:6.67%;font-size:12pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The Company also contracts with various customers to carry out management services for vessels as agents for and on behalf of ship owners. These services include crew management, technical management, commercial management, insurance arrangements, sale and purchase of vessels, provisions and bunkering. As the manager of the vessels, the Company undertakes to use its best endeavors to provide the agreed management services as agents for and on behalf of the owners in accordance with sound ship management practice and to protect and promote the interest of the owners in all matters relating to the provision of services thereunder. The Company also contracts with various customers to carry out management services regarding engineering for vessel construction and vessel conversions. The vast majority of the ship management agreements span one to three years and are typically billed on a monthly basis. The Company transfers control of the service to the customer and satisfies its performance obligation over the term of the contract, and therefore recognizes revenue over the term of the contract while related costs are expensed as incurred.</p> <p style="text-align:justify;margin-bottom:0pt;margin-top:10pt;text-indent:6.67%;font-size:12pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Revenue that does not meet these criteria is deferred until the criteria is met and is considered a contract liability and is recognized as such.

Customers are granted credit on a short-term basis and the related credit risks are minimal. Other receivables consist primarily of operating expenses the Company incurs in relation to vessels it manages for other entities, as well as insurance and income tax receivables. The Company routinely reviews its receivables and makes provisions for the credit losses utilizing the Current Expected Credit Losses model (CECL). The CECL model utilizes a lifetime expected credit loss measurement objective for the recognition of credit losses for loans and other receivables at the time the financial asset is originated or acquired. However, those provisions are estimates and actual results may materially differ from those estimates.

With respect to each class of asset, the estimated useful life is based upon a newly built asset being placed into service and represents the time period beyond which it is typically not justifiable for the Company to continue to operate the asset in the same or similar manner. From time to time, the Company may acquire older assets that have already exceeded the Company’s useful life policy, in which case the Company depreciates such assets based on its best estimate of remaining useful life, typically the next survey or certification date.</span></p> <p style="text-align:justify;margin-bottom:0pt;margin-top:10pt;text-indent:6.67%;font-size:12pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">As of September 30, 2021, the estimated useful life (in years) of the Company’s new Offshore Support Vessels was 20 years.</p> <p style="text-align:justify;margin-bottom:0pt;margin-top:0pt;text-indent:6.67%;font-family:Times New Roman;font-size:12pt;"> </p> <p style="text-align:justify;margin-bottom:0pt;margin-top:0pt;text-indent:6.67%;font-size:12pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Equipment maintenance and repair costs and the costs of routine overhauls, drydockings and inspections performed on vessels and equipment are charged to operating expense as incurred.

These indicators may include a significant decrease in the market price of a long-lived asset or asset group, a significant adverse change in the extent or manner in which a long-lived asset or asset group is being used or in its physical condition, or a current period operating or cash flow loss combined with a history of operating or cash flow losses or a forecast that demonstrates continuing losses associated with the use of a long-lived asset or asset group. If the carrying values of the assets are not recoverable, as determined by their estimated future undiscounted cash flows, the estimated fair value of the assets or asset groups are compared to their current carrying values and impairment charges are recorded if the carrying value exceeds fair value.</span></p> <p style="text-align:justify;margin-bottom:0pt;margin-top:10pt;text-indent:6.67%;font-size:12pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Market conditions caused by COVID-19, including decreased global demand for oil and gas as well as the effect the pandemic has had on SEACOR Marine’s stock price, caused a triggering event for the nine months ended September 30, 2021 and 2020 to occur requiring the Company to test its assets for impairment. For the nine months ended September 30, 2021, the Company did not record an impairment on any owned or leased-in vessels. For the nine months ended September 30, 2020, the Company recorded impairment charges of $3.9 million related to four owned liftboats, $7.4 million related to two leased-in liftboats, and $1.2 million related to one specialty vessel due to a reduced sales price for the vessel. Estimated fair values for the Company’s owned vessels were established by independent appraisers based on researched market information, replacement cost information, and other data.<span style="font-family:Calibri;font-size:11pt;"> </span><span style="Background-color:#FFFFFF;color:#000000;"> </span><span style="font-family:Calibri;font-size:11pt;"> </span></p> <p style="text-align:justify;margin-top:10pt;margin-bottom:8pt;text-indent:6.67%;font-size:12pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">For vessel classes and individual vessels with indicators of impairment as of September 30, 2021, the Company estimated that their future undiscounted cash flows exceeded their current carrying values. However, the Company’s estimates of future undiscounted cash flows are highly subjective as utilization and rates per day worked are uncertain, especially in light of the continued volatility in commodity prices and the effect COVID-19 has had on the timing of an estimated market recovery in the offshore oil and natural gas markets and upon any such recovery, the timing and cost of reactivating cold-stacked vessels. If market conditions decline further, changes in the Company’s expectations on future cash flows may result in recognizing additional impairment charges related to its long-lived assets in future periods. For any vessel or vessel class that have indicators of impairment and are deemed not recoverable through future operations, we determine the fair value of the vessel or vessel class. If the fair value determination is less than the carrying value of the vessel or vessel class, an impairment is recognized to reduce the carrying value to fair value. Fair value determination is primarily accomplished by obtaining independent valuations of vessel or vessel classes from qualified third-party appraisers. </p> <p style="text-align:justify;margin-bottom:0pt;margin-top:10pt;text-indent:6.67%;font-weight:bold;font-style:italic;font-size:12pt;font-family:Times New Roman;text-transform:none;font-variant: normal;">Impairment of <span style="font-style:normal;">50%</span> or Less Owned Companies.<span style="font-weight:normal;font-style:normal;"> Investments in 50% or less owned companies are reviewed periodically to assess whether there is an other-than-temporary decline in the carrying value of the investment. In its evaluation, the Company considers, among other items, recent and expected financial performance and returns, impairments recorded by the investee and the capital structure of the investee. When the Company determines the estimated fair value of an investment is below carrying value and the decline is other-than-temporary, the investment is written down to its estimated fair value. Actual results may vary from the Company’s estimates due to the uncertainty regarding projected financial performance, the severity and expected duration of declines in value and the available liquidity in the capital markets to support the continuing operations of the investee, among other factors. Although the Company believes its assumptions and estimates are reasonable, the investee’s actual performance compared with the estimates could produce different results and lead to additional impairment charges in future periods. During the nine months ended September 30, 2021 and 2020, the Company did not recognize any impairment charges related to its 50% or less owned companies.</span></p> <p style="text-align:justify;margin-bottom:0pt;margin-top:10pt;text-indent:6.67%;font-weight:bold;font-style:italic;font-size:12pt;font-family:Times New Roman;text-transform:none;font-variant: normal;">Income Taxes.<span style="font-weight:normal;font-style:normal;"> During the nine months ended September 30, 2021, the Company’s effective income tax rate of 24.56% was primarily due to foreign taxes not creditable against U.S. income taxes offset by the impact of foreign sourced income not subject to U.S. income taxes. For the nine months ended September 30, 2020, the Company’s effective income tax rate of 34.97% was primarily due to taxes provided on income attributable to noncontrolling interest, foreign sourced income not subject to U.S. income taxes, foreign taxes not creditable against U.S. income taxes, and an adjustment for the acquisition of the remaining minority membership interest in a consolidated subsidiary.</span></p> <p style="text-align:justify;margin-bottom:0pt;margin-top:10pt;text-indent:6.67%;font-weight:bold;font-style:italic;font-size:12pt;font-family:Times New Roman;text-transform:none;font-variant: normal;">Accumulated Other Comprehensive Income (Loss).<span style="font-weight:normal;font-style:normal;"> The components of accumulated other comprehensive loss were as follows (in thousands):</span></p> <p style="text-align:justify;margin-bottom:0pt;margin-top:0pt;text-indent:0%;font-family:Times New Roman;font-size:10pt;"> </p> <div style="align:left;"> <table border="0" cellpadding="0" cellspacing="0" style="border-collapse:collapse;

The Warrants are included in the basic earnings/loss per share of Common Stock because the shares issuable upon exercise of the Warrants are issuable for de minimis cash consideration and therefore not anti-dilutive. Diluted earnings/loss per share of Common Stock is computed based on the weighted average number of shares of Common Stock and Warrants issued and outstanding plus the effect of other potentially dilutive securities through the application of the treasury stock method and the if-converted method that assumes all shares of Common Stock have been issued and outstanding during the relevant periods pursuant to the conversion of the Convertible Senior Notes (as defined in “Note 4. Long-Term Debt”) unless anti-dilutive. </span></p> <p style="text-align:justify;margin-bottom:8pt;margin-top:0pt;text-indent:6.67%;font-size:12pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The Convertible Senior Notes are currently convertible into 2,907,500 shares of Common Stock (“Convertible Senior Note Shares”).

The number of Convertible Senior Note Shares excluded from the calculation of diluted earnings per share was incorrectly reported in certain prior periods as 2,183,708.

Such estimates include those related to deferred revenues, allowance for credit loss accounts, useful lives of property and equipment, impairments, income tax provisions and certain accrued liabilities.
