Restricted cash also includes bank deposits and deposits in so-called “retention accounts” that are required under the Company’s borrowing arrangements which are used to fund the loan installments coming due. The funds can only be used for the purposes of loan repayment. A reconciliation of the cash, cash equivalents and restricted cash is presented in the table below: For the years ended December 31, 2020 2021 2022 Reconciliation of cash, cash equivalents and restricted cash Cash and cash equivalents $ 143,922 $ 276,002 $ 718,049 Restricted cash – current portion 4,998 8,856 9,768 Restricted cash – non-current portion 42,976 68,670 83,741 Total cash, cash equivalents and restricted cash $ 191,896 $ 353,528 $ 811,558 (f) Accounts Receivable, net: 842 not 326. 842 not December 31, 2021 2022, nil (g) Inventories: first first (h) Insurance Claims Receivable: not 326 no (i) Vessels, Net: The cost of each of the Company’s vessels is depreciated from the date of acquisition on a straight-line basis over the vessel’s remaining estimated economic useful life, after considering the estimated residual value which is equal to the product of vessels’ lightweight tonnage and estimated scrap rate. Management estimates the useful life of the Company’s container and dry bulk vessels to be 30 and 25 years, respectively, from the date of initial delivery from the shipyard and the estimated scrap rate used to calculate the vessels’ salvage value is $0.300 per lightweight ton for both container and dry bulk vessels. Secondhand container and dry bulk vessels are depreciated from the date of their acquisition through their remaining estimated useful life. If the estimated economic lives assigned to the Company’s vessels prove to be too long because of unforeseen events such as an extended period of weak markets, the broad imposition of age restrictions by the Company’s customers’, new regulations, or other future events, the remaining estimated useful life of any affected vessel is adjusted accordingly.

Changes in the fair value of the interest rate caps are reported within accumulated other comprehensive income. The initial value of the component excluded from the assessment of effectiveness is recognized in earnings using a systematic and rational method over the life of the hedging instrument. Any amounts excluded from the assessment of hedge effectiveness are presented in the same income statement line being Interest and finance costs where the earnings effect of the hedged item is presented. The Company formally documents all relationships between hedging instruments and hedged items, as well as the risk-management objective and strategy for undertaking various hedge transactions. This process includes linking all derivatives that are designated as cash flow hedges to specific forecasted transactions or variability of cash flow. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flow of hedged items. The Company considers a hedge to be highly effective if the change in fair value of the derivative hedging instrument is within 80% to 125% of the opposite change in the fair value of the hedged item attributable to the hedged risk. When it is determined that a derivative is not 815 Also, the Company enters into FFAs to establish market positions in the dry bulk derivative freight markets and to hedge its exposure in the physical dry bulk freight markets and into bunker swap agreements to hedge its exposure to bunker prices.

At the commencement date of the finance lease, a lessee initially measures the lease liability at the present value, using the discount rate determined on the commencement, of the lease payments to be made over the lease term. Subsequently, the lease liability is increased by the interest on the lease liability and decreased by the lease payments during the period. The interest on the lease liability is determined in each period during the lease term A lessee initially measures the finance right-of-use asset at cost which consists of the amount of the initial measurement of the lease liability; any lease payments made to the lessor at or before the commencement date, less any lease incentives received; and any initial direct costs incurred by the lessee. Subsequently, the finance right-of-use asset is measured at cost less any accumulated amortization and any accumulated impairment losses, taking into consideration the reassessment requirements. A lessee shall amortize the finance right-of-use asset on a straight-line basis (unless another systematic basis better represents the pattern in which the lessee expects to consume the right-of-use asset’s future economic benefits) from the commencement date For sale and leaseback transactions, if the transfer is not 842 40 25 1 25 3, not 360.

Management estimates the useful life of the Company’s container and dry bulk vessels to be 30 and 25 years, respectively, from the date of initial delivery from the shipyard and the estimated scrap rate used to calculate the vessels’ salvage value is $0.300 per lightweight ton for both container and dry bulk vessels. Secondhand container and dry bulk vessels are depreciated from the date of their acquisition through their remaining estimated useful life. If the estimated economic lives assigned to the Company’s vessels prove to be too long because of unforeseen events such as an extended period of weak markets, the broad imposition of age restrictions by the Company’s customers’, new regulations, or other future events, the remaining estimated useful life of any affected vessel is adjusted accordingly.

Derivatives, Policy [Policy Text Block]	(q) Derivative Financial Instruments: may zero The interest rate caps are accounted for as cash flow hedges when they are expected to be highly effective in hedging variable rate interest payments under certain term loans. Changes in the fair value of the interest rate caps are reported within accumulated other comprehensive income. The initial value of the component excluded from the assessment of effectiveness is recognized in earnings using a systematic and rational method over the life of the hedging instrument. Any amounts excluded from the assessment of hedge effectiveness are presented in the same income statement line being Interest and finance costs where the earnings effect of the hedged item is presented. The Company formally documents all relationships between hedging instruments and hedged items, as well as the risk-management objective and strategy for undertaking various hedge transactions. This process includes linking all derivatives that are designated as cash flow hedges to specific forecasted transactions or variability of cash flow. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flow of hedged items. The Company considers a hedge to be highly effective if the change in fair value of the derivative hedging instrument is within 80% to 125% of the opposite change in the fair value of the hedged item attributable to the hedged risk.

At the commencement date of the finance lease, a lessee initially measures the lease liability at the present value, using the discount rate determined on the commencement, of the lease payments to be made over the lease term. Subsequently, the lease liability is increased by the interest on the lease liability and decreased by the lease payments during the period. The interest on the lease liability is determined in each period during the lease term A lessee initially measures the finance right-of-use asset at cost which consists of the amount of the initial measurement of the lease liability; any lease payments made to the lessor at or before the commencement date, less any lease incentives received; and any initial direct costs incurred by the lessee. Subsequently, the finance right-of-use asset is measured at cost less any accumulated amortization and any accumulated impairment losses, taking into consideration the reassessment requirements. A lessee shall amortize the finance right-of-use asset on a straight-line basis (unless another systematic basis better represents the pattern in which the lessee expects to consume the right-of-use asset’s future economic benefits) from the commencement date For sale and leaseback transactions, if the transfer is not 842 40 25 1 25 3, not 360.
