In these circumstances, the Company performs step one of the impairment test by comparing the undiscounted projected net operating cash flows for each vessel group to its carrying value. A vessel group comprises the vessel, the unamortized portion of deferred drydocking related to the vessel and the related carrying value of the intangible asset or liability (if any) with respect to the time charter attached to the vessel at its purchase. If the undiscounted projected net operating cash flows of the vessel group are less than its carrying amount, management proceeds to step two of the impairment assessment by comparing the vessel group’s carrying amount to its fair value, including any applicable charter, and an impairment loss is recorded equal to the difference between the vessel group’s carrying value and fair value. Fair value is determined with the assistance from valuations obtained from third party independent ship brokers.</span></p> <p style="font: 9pt Times New Roman, Times, Serif; margin: 0; text-align: justify"></p> <p style="font: 9pt Times New Roman, Times, Serif; margin: 0; text-align: justify"></p> <p style="font: 9pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font-size: 10pt"><b></b></span></p> <p style="font: 9pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font-size: 10pt"><b> </b></span></p> <p style="font: 9pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span id="xdx_90E_ecustom--FutureCharterRateAssumptions_c20230401__20230630_zzsstbFZ6nzk" style="font-size: 10pt" title="Future charter rate assumptions">The Company uses a number of assumptions in projecting its undiscounted net operating cash flows analysis including, among others, (i) revenue assumptions for charter rates on expiry of existing charters, which are based on forecast charter rates, where relevant, in the four years from the date of the impairment test and a reversion to the historical mean of time charter rates for each vessel thereafter (ii) off-hire days, which are based on actual off-hire statistics for the Company’s fleet (iii) operating costs, based on current levels escalated over time based on long term trends (iv) dry docking frequency, duration and cost (v) estimated useful life, which is assessed as a total of 30 years from original delivery by the shipyard and (vi) scrap values.</span></p> <p style="font: 9pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 9pt Times New Roman, Times, Serif; margin: 0; text-align: center"></p> <p style="font: 9pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 9pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><b>2.

Use Of Estimates

UseOfEstimates

(c) Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates under different assumptions and/or conditions.

Property Plant And Equipment Impairment

PropertyPlantAndEquipmentImpairment

(l) Impairment of Long-lived assets Tangible fixed assets, such as vessels, that are held and used or to be disposed of by the Company are reviewed for impairment when events or changes in circumstances indicate that their carrying amounts may not be recoverable. In these circumstances, the Company performs step one of the impairment test by comparing the undiscounted projected net operating cash flows for each vessel group to its carrying value. A vessel group comprises the vessel, the unamortized portion of deferred drydocking related to the vessel and the related carrying value of the intangible asset or liability (if any) with respect to the time charter attached to the vessel at its purchase. If the undiscounted projected net operating cash flows of the vessel group are less than its carrying amount, management proceeds to step two of the impairment assessment by comparing the vessel group’s carrying amount to its fair value, including any applicable charter, and an impairment loss is recorded equal to the difference between the vessel group’s carrying value and fair value. Fair value is determined with the assistance from valuations obtained from third party independent ship brokers. The Company uses a number of assumptions in projecting its undiscounted net operating cash flows analysis including, among others, (i) revenue assumptions for charter rates on expiry of existing charters, which are based on forecast charter rates, where relevant, in the four years from the date of the impairment test and a reversion to the historical mean of time charter rates for each vessel thereafter (ii) off-hire days, which are based on actual off-hire statistics for the Company’s fleet (iii) operating costs, based on current levels escalated over time based on long term trends (iv) dry docking frequency, duration and cost (v) estimated useful life, which is assessed as a total of 30 years from original delivery by the shipyard and (vi) scrap values. 2. Summary of Significant Accounting Policies (continued) (I) Impairment of Long-lived assets (continued) Revenue assumptions are based on contracted charter rates up to the end of the existing contract of each vessel, and thereafter, estimated time charter rates for the remaining life of the vessel. The estimated time charter rate used for non-contracted revenue days of each vessel is considered a significant assumption. Recognizing that the container shipping industry is cyclical and subject to significant volatility based on factors beyond the Company’s control, management believes that using forecast charter rates in the four years from the date of the impairment assessment and a reversion to the historical mean of time charter rates thereafter, represents a reasonable benchmark for the estimated time charter rates for the non-contracted revenue days, and takes into account the volatility and cyclicality of the market. Through the latter part of 2023, the Company noted that events and circumstances triggered the existence of potential impairment for some of the Company’s vessel groups. These indicators included volatility in the charter market and the vessels’ market values, as well as the potential impact of the current container sector on management’s expectation for future revenues. As a result, the Company performed step one of the impairment assessment of each of the Company’s vessel groups by comparing the undiscounted projected net operating cash flows for each vessel group to their carrying value and step two of the impairment analysis was required for two vessel groups, as their undiscounted projected net operating cash flows did not exceed their carrying value. As a result, the Company recorded an impairment loss of $18,830 for two vessel groups with a total aggregate carrying amount of $43,830 which was written down to their fair value of $25,000 (see note 4). Through the latter part of 2022, the Company noted that charter rates in the spot market had come under pressure and accordingly determined that events occurred and circumstances had changed, which indicated that potential impairment of the Company’s long-lived assets could exist. These indicators included continued volatility in the spot market and the related impact of the current container sector on management’s expectation for future revenues. As a result, step one of the impairment assessment of each of the vessel groups was performed as at December 31, 2022 and step two of the impairment analysis was required for one vessel group, as its undiscounted projected net operating cash flows did not exceed its carrying value. As a result, the Company recorded an impairment loss of $3,033 for one vessel asset group with a total aggregate carrying amount of $9,033 which was written down to its fair value of $6,000 (see note 4). Through 2021, the Company evaluated the impact of the then economic situation on the recoverability of all its vessel groups and determined that there was no triggering event and no impairment test was performed for the year ended December 31, 2021.
