Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation The consolidated financial statements include the accounts of the Company and subsidiaries in which it has a controlling interest, and variable interest entities of which the Company is the primary beneficiary. The equity method of accounting is applied when the Company does not have a controlling interest in an entity but exerts significant influence over the entity. All significant intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities in the financial statements. Such estimates include, but are not limited to, the Company's estimates in connection with leasing equipment, including residual values and depreciable lives, values of assets held for sale and other long lived assets, provision for income tax, allowance for doubtful accounts, share-based compensation, goodwill and intangible assets. Actual results could differ from those estimates. Segment Reporting The Company conducts its business activities in one industry, intermodal transportation equipment, and has two reporting segments, Equipment leasing and Equipment trading. The Company also segregates total equipment leasing revenues and total equipment trading revenues by geographic location based upon the primary domicile of the Company's customers. Concentration of Credit Risk The Company's equipment leases and trade receivables subject it to potential credit risk. The Company extends credit to its customers based upon an evaluation of each customer's financial condition and credit history. Evaluations of the financial condition and associated credit risk of customers are performed on an ongoing basis. The Company's largest customer accounted for 22%, 21%, and 20% of its lease billings during 2020, 2019, and 2018, respectively, and accounted for 23% and 21% of its accounts receivable as of December 31, 2020 and 2019, respectively. The Company's second largest customer accounted for 14% of its lease billings each year during 2020, 2019, and 2018, and accounted for 6% of its accounts receivable as of both December 31, 2020 and 2019. Other financial instruments that are exposed to concentration of credit risk are cash and cash equivalents, and restricted cash balances. Cash and cash equivalents, and restricted cash are held with financial institutions of high quality. Balances may exceed the amount of insurance provided on such deposits. Fair Value Measurements Fair value represents the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The determination of fair value may require an entity to make significant judgments or develop assumptions about market participants to reflect risks specific to the asset being valued. The Company uses the following fair value hierarchy when selecting inputs for its valuation techniques, with the highest priority given to Level 1: • Level 1—quoted prices (unadjusted) in active markets for identical assets or liabilities; • Level 2—inputs other than quoted prices included within Level 1 that are either directly or indirectly observable; and • Level 3—unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its own assumptions about the assumptions that market participants would use in pricing. Cash and cash equivalents, restricted cash, accounts receivable, equipment purchases payable and accounts payable carrying amounts approximate fair values because of the short-term nature of these instruments. The Company's other financial and non-financial assets, which include leasing equipment, net investment in finance leases, intangible assets and goodwill, are not required to be measured at fair value on a recurring basis. However, if certain triggering events occur, or if an annual impairment test is required, and the Company determines that these other financial and non-financial assets are impaired after completing an evaluation, these assets would be written down to their fair value. For information on the fair value of equipment held for sale, debt, and the fair value of derivative instruments, please refer to Note 3 - "Equipment Held for Sale", Note 6 - "Debt" and Note 7 - "Derivative Instruments", respectively. Cash and Cash Equivalents Cash and cash equivalents consist of all cash balances and highly liquid investments having original maturities of three months or less at the time of purchase. Restricted Cash The Company's restricted cash relates to amounts held at financial institutions pursuant to certain debt arrangements. The restricted cash balances represent cash proceeds collected and required to be used to pay debt service and other related expenses. Allowance for Doubtful Accounts The Company's allowance for doubtful accounts is estimated based upon a review of the collectibility of its receivables. This review is based on the risk profile of the receivables, credit quality indicators such as the level of past-due amounts and economic conditions. Generally, the Company does not require collateral on accounts receivable balances. An account is considered past due when a payment has not been received in accordance with the contractual terms. Changes in economic conditions or other events may necessitate additions or deductions to the allowance for doubtful accounts. The allowance for doubtful accounts is intended to provide for losses in the receivables, and requires the application of estimates and judgments as to the outcome of collection efforts, among other things. The Company believes its allowance for doubtful accounts is adequate to provide for credit losses inherent in its existing receivables. For our net investment in finance leases and accounts receivable for sales of equipment, the Company measures expected credit loss by evaluating the overall credit quality of its customers. Expected credit losses for these financial assets are estimated using historical experience which includes multiple economic cycles, customer payment history, management's assessment of the customer's financial condition, and consideration of current conditions and reasonable forecasts. Net Investment in Finance Leases The Company has entered into various lease agreements that qualify as sales-type leases. These leases are usually long-term in nature, ranging for a period of three to twelve years, and typically include an option to purchase the equipment at the end of the lease term for a nominal price that the Company deems reasonably certain to be exercised. At the inception of a sales-type lease, a net investment is recorded based on the gross investment (representing the total future minimum lease payments plus the estimated residual value), net of unearned income. Unearned income represents the excess of the gross investment over the fair value of the leased equipment at lease commencement. Any gain or loss is recognized at commencement and recorded in Net gain on sale of leasing equipment. Leasing Equipment The Company purchases new equipment from equipment manufacturers for the purpose of leasing such equipment to customers. The Company also purchases used equipment with the intention of selling such equipment in one or more years from the date of purchase. Leasing equipment is recorded at cost and depreciated to an estimated residual value on a straight-line basis over the estimated useful lives. Capitalized costs for new container rental equipment include the manufactured cost of the container, inspection, delivery, and associated costs incurred in moving the container from the manufacturer to the initial on-hire location of such container. Repair and maintenance costs that do not extend the lives of the container rental equipment are charged to direct operating expenses at the time the costs are incurred. The estimated useful lives and residual values of the Company's leasing equipment are based on historical disposal experience and the Company's expectations for future used container sale prices. The Company evaluates estimates used in its depreciation policy on a regular basis to determine whether changes have taken place that would suggest that a change in its depreciation estimates for useful lives or the assigned residual values of its equipment is warranted. For 2020, the Company completed its annual depreciation policy assessment during the fourth quarter and concluded no change was necessary. The estimated useful lives and residual values for each major equipment type for the periods indicated below were as follows: As of December 31, 2020 and 2019 Equipment Type Depreciable Life Residual Value Dry containers 20-foot dry container 13 years $ 1,000 40-foot dry container 13 years $ 1,200 40-foot high cube dry container 13 years $ 1,400 Refrigerated containers 20-foot refrigerated container 12 years $ 2,350 40-foot high cube refrigerated container 12 years $ 3,350 Special containers 40-foot flat rack container 16 years $ 1,700 40-foot open top container 16 years $ 2,300 Tank containers 20 years $ 3,000 Chassis 20 years $ 1,200 Depreciation on leasing equipment commences on the date of initial on-hire. For leasing equipment purchased for resale that may be leased for a period of time, the Company adjusts its estimates for remaining useful life and residual values based on current conditions in the sales market for older containers and the Company's expectations for how long the equipment will remain on-hire to the current lessee. The net book value of the Company's leasing equipment by equipment type as of the dates indicated was (in thousands): December 31, 2020 December 31, 2019 Dry container $ 6,589,960 $ 6,308,038 Refrigerated container 1,483,820 1,520,747 Special container 307,765 321,099 Tank container 97,982 101,677 Chassis 151,169 140,986 Total $ 8,630,696 $ 8,392,547 Included in the amounts above are units not on lease at December 31, 2020 and 2019 with a total net book value of $173.2 million and $721.7 million, respectively. Depreciation on equipment purchased under finance lease obligations is included in depreciation and amortization expense on the consolidated statements of operations. Valuation of Leasing Equipment Leasing equipment is evaluated for impairment whenever events or changes in circumstances indicate that its carrying value may not be recoverable. Recoverability of an asset to be held and used is measured by a comparison of the carrying value to its estimated undiscounted future cash flows expected to be generated by the asset. If the carrying value of an asset exceeds its estimated undiscounted future cash flows, an impairment charge is recognized in the amount by which the carrying value of the asset exceeds the fair value of the asset. Key indicators of impairment on leasing equipment include, among other factors, a sustained decrease in operating profitability, a sustained decrease in utilization, or indications of technological obsolescence. When testing for impairment, leasing equipment is generally grouped by equipment type, and is tested separately from other groups of assets and liabilities. Some of the significant estimates and assumptions used to determine future undiscounted cash flows and the measurement for impairment are the remaining useful life, expected utilization, expected future lease rates and expected disposal prices of the equipment. The Company considers the assumptions on expected utilization and the remaining useful life to have the greatest impact on its estimate of future undiscounted cash flows. These estimates are principally based on the Company's historical experience and management's judgment of market conditions. The Company did not record any impairment charges related to leasing equipment for the years ended December 31, 2020, 2019, and 2018. Equipment Held for Sale When leasing equipment is returned off lease, the Company makes a determination of whether to repair and re-lease the equipment or sell the equipment. At the time the Company determines that equipment will be sold, it reclassifies the appropriate amounts previously recorded as leasing equipment to equipment held for sale. Equipment held for sale is recorded at the lower of its estimated fair value less costs to sell or carrying value at the time identified for sale. Depreciation expense on equipment held for sale is halted and disposals generally occur within 90 days. Initial write downs of equipment held for sale to fair value are recorded as an impairment charge and are included in net gain on sale of leasing equipment. Subsequent increases or decreases to the fair value of those assets are recorded as adjustments to the carrying value of the equipment held for sale, however, any such adjustments may not exceed the respective equipment's carrying value at the time it was initially classified as held for sale. Realized gains and losses resulting from the sale of equipment held for sale are recorded in Net gain on sale of leasing equipment, and cash flows associated with the disposal of equipment held for sale are classified as cash flows from investing activities. Equipment recorded within our equipment trading segment is also included in Equipment held for sale. Gains and losses resulting from the sale of this equipment is recorded in Trading margin, and cash flows associated with the sale of this equipment are classified as cash flows from operating activities. Operating Leases The Company leases office space and office equipment and evaluates whether these leases are classified as operating or financing at the inception of the lease. The classification is based on certain assumptions that require judgment, such as the asset's fair value, the asset's estimated residual value, the interest rate implicit in the lease, and the asset's economic useful life. For operating leases, the Company records a lease liability based on the present value of the remaining minimum payments and a corresponding right-of-use ("ROU") asset. The Company uses its estimated incremental borrowing rate at the commencement date to determine the present value of lease payments. The benefits of lease incentives, including rent-free or reduced rent periods, and the cost of future rent escalations are recognized on a straight-line basis over the term of the lease. A lease liability and a corresponding ROU asset are not recognized when, at the commencement date of the lease, the term is 12 months or less. Property, Furniture and Equipment Costs of major additions of property, furniture, equipment and improvements are capitalized and are included in other assets on the consolidated balance sheets. The original cost is depreciated on a straight-line basis over the estimated useful lives of such property, furniture and equipment. Leasehold improvements are amortized on a straight-line basis over the shorter of the lease term or the estimated useful lives of the leased assets. Other fixed assets, which consist primarily of computer software and hardware, are recorded at cost and amortized on a straight-line basis over their respective estimated useful lives, which range from three to seven years. Expenditures for maintenance and repairs are expensed as they are incurred. Goodwill Goodwill is tested for impairment at least annually on October 31st of each fiscal year or more frequently if events occur or circumstances indicate that the fair value of a reporting unit may be below its carrying value. Goodwill has been allocated to the Company's reporting units, which are the same as its reporting segments. In evaluating goodwill for impairment, the Company has the option to first assess qualitative factors to determine whether further impairment testing is necessary. Among the relevant events and circumstances that affect the fair value of reporting units, the Company considers individual factors such as macroeconomic conditions, changes in its industry and the markets in which the Company operates, as well as its reporting units' historical and expected future financial performance. If, after assessing the totality of events or circumstances, the Company determines it is more-likely-than-not that the fair value of a reporting unit is greater than its carrying amount, then the quantitative goodwill impairment test is unnecessary. The quantitative goodwill impairment test compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount of the reporting unit is less than its fair value, no impairment exists. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. The Company elected to perform the qualitative assessment for its evaluation of goodwill impairment during the year ended December 31, 2020 and concluded there was no impairment. Since inception through December 31, 2020, the Company has not recorded any goodwill impairment. Intangible Assets Intangible assets with finite useful lives such as acquired lease intangibles are initially recorded at fair value and are amortized over their respective estimated useful lives and subsequently reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. The Company has not recorded any impairment charges related to intangible assets for the years ended December 31, 2020, 2019, and 2018. Revenue Recognition Operating Leases with Customers The Company enters into long-term leases and service leases with ocean carriers, principally as lessor in operating leases, for marine cargo equipment. Long-term leases provide customers with specified equipment for a specified term. The Company's leasing revenues are based upon the number of equipment units leased, the applicable per diem rate and the length of the lease. Long-term leases typically have initial contractual terms ranging from three to eight or more years. Revenues are recognized on a straight-line basis over the life of the respective lease. Revenue from advance billings are deferred and recognized in the period earned. Service leases do not specify the exact number of equipment units to be leased or the term that each unit will remain on-hire, but allow the lessee to pick-up and drop-off units at various locations specified in the lease agreement. Under a service lease, rental revenue is based on the number of equipment units on-hire for a given period. Revenue from customers considered to be non-performing is deferred and recognized when the amounts are received. The Company recognizes billings to customers for damages and certain other operating costs as leasing revenue when earned based on the terms of the contractual agreements with the customer. Finance Leases with Customers The Company enters into finance leases as lessor for some of the equipment in its fleet. At the inception of the lease, the Company records the total future minimum lease payments plus the estimated residual value, net of executory costs, if any. The net investment in finance leases represents the receivables due from lessees, net of unearned income and amounts previously billed, which are included in accounts receivable. Unearned income, which also includes any initial direct costs, is recognized on a constant yield basis over the lease term and is recorded as leasing revenue. The Company's finance leases are usually long-term in nature and typically include an option to purchase the equipment at the end of the lease term for a nominal price that the Company deems reasonably certain to be exercised. Equipment Trading Revenues and Expenses Equipment trading revenues represent the proceeds from the sale of equipment purchased for resale and are recognized as units are sold. The related expenses represent the cost of equipment sold as well as other selling costs that are recognized as incurred and are reflected as equipment trading expenses on the consolidated statements of operations. Direct Operating Expenses Direct operating expenses are directly related to the Company's equipment under and available for lease. These expenses primarily consist of the Company's costs to repair and maintain the equipment, to reposition the equipment and to store the equipment when it is not on lease. These costs are recognized when incurred. Certain positioning costs may be capitalized when incurred to place new equipment on an initial lease. Debt Costs Debt costs represent the fees incurred in connection with debt obligation arrangements. These costs are capitalized and amortized using the effective interest method or on a straight-line basis over the term of the related obligation, depending on the type of debt obligation to which they relate. Unamortized debt costs may be written off when the related debt obligations are refinanced or extinguished prior to maturity. Derivative Instruments The Company uses derivatives in the management of its interest rate exposure on its long-term borrowings. The Company records derivative instruments on its balance sheet at fair value and establishes criteria for both the designation and effectiveness of hedging activities. The Company has entered into interest rate swap agreements with certain financial institutions. The interest rate swap agreements require the Company to make payments to counterparties at fixed rates in return for receipts based upon variable rates indexed to the London Interbank Offered Rate ("LIBOR") or its replacement rate. Derivative instruments are designated or non-designated for hedge accounting purposes. The fair value of the derivative instruments is measured at each balance sheet date and is reflected on a gross basis on the consolidated balance sheets. The change in fair value of the derivative instruments designated as a cash flow hedge are recorded on the consolidated balance sheets in accumulated other comprehensive income (loss) and are re-classified to interest and debt expense when the hedged interest payments are recognized. The change in fair value of non-designated derivative instruments is recorded in the consolidated statements of operations as unrealized loss (gain) on derivative instruments, net and are reclassified to realized loss (gain) on derivative instruments, net when net settlement amounts required under interest rate swap agreements are paid or received. Income Taxes The Company uses the liability method of accounting for income taxes, which requires recognition of deferred tax assets and liabilities based on the expected future tax consequences of temporary differences that currently exist between the tax basis and financial reporting basis of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Any change in the tax rate which has an effect on deferred tax assets and liabilities is recognized as an increase or decrease to income in the period that includes the enactment date of the law that resulted in the change in tax rate. The Company recognizes the effect of income tax positions which are more-likely-than-not of being sustained. If a position does not meet the more-likely-than-not criteria, the Company records a reserve against the tax position such that a tax benefit is recognized only in the amount that has a greater than 50% likelihood of being recognized. The full impact of any change in recognition or measurement of an uncertain tax position is reflected in the period in which such change occurs. Potential interest and penalties associated with such uncertain tax positions are recorded as a component of income tax expense. Noncontrolling Interests During 2019, the Company acquired all of the remaining third-party partnership interests in Triton Container Investments LLC ("TCI"), a fully consolidated entity, for an aggregate of $103.0 million in cash and recognized a benefit of $16.9 million in the consolidated statements of shareholders' equity. Foreign Currency Translation and Remeasurement The Company uses the U.S. dollar as its reporting currency. The net assets and operations that are denominated in foreign currency and are subject to foreign currency translation included in the consolidated financial statements are attributable primarily to the Company's U.K. subsidiary. The accounts of this subsidiary have been converted at rates of exchange in effect at year end as to balance sheet accounts and at the annual weighted average exchange rates for the statements of operations accounts. The effects of changes in exchange rates in translating foreign subsidiaries' financial statements are included in shareholders' equity as accumulated other comprehensive (loss) income. The Company also has certain cash accounts, certain finance lease receivables and certain obligations that are denominated in currencies other than the Company's functional currency. These assets and liabilities are generally denominated in euros or British pounds, and are remeasured at each balance sheet date at the exchange rates in effect as of those dates. The impact of changes in exchange rates on the remeasurement of assets and liabilities are included in administrative expenses on the consolidated statements of operations. Foreign currency gains or losses were immaterial for the years ended December 31, 2020, 2019, and 2018. Share-based Compensation The Company measures and recognizes share-based awards granted to employees based on the grant date fair value. Share-based awards may be subject to forfeiture if certain employment conditions are not met. The Company has elected to account for forfeitures as they occur. Time based awards are measured at the grant date and are recognized as compensation expense over the employee's requisite service period, generally the vesting period of the equity award, on a straight-line basis. Performance-based awards are recognized as compensation expense when satisfaction of the performance condition is considered probable. The Company also grants share-based awards to non-employee directors that vest immediately and are recognized as compensation expense based on the grant date fair value. Earnings Per Share Basic earnings per share is computed by dividing net income attributable to common shareholders by the weighted average number of common shares outstanding for the period. Any potential issuance of common shares, including those that are contingent and do not participate in dividends, are excluded from the weighted average number of common shares outstanding. Diluted earnings per share reflect the potential dilution that would occur if securities exercisable or convertible into common shares were exercised or converted into common shares, utilizing the treasury share method. The Company excluded anti-dilutive restricted common shares from its calculation of diluted earnings per share of 1,576 for the year ended December 31, 2020, 867 for the year ended December 31, 2019, and 207,991 for the year ended December 31, 2018. Recently Adopted Accounting Standards Updates Measurement of Credit Losses on Financial Instruments In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) and subsequently issued amendments. The guidance affects the Company's net investment in finance leases and accounts receivable for sales of equipment. The standard requires the measurement of expected credit losses to be based on relevant information from past events, including historical experiences, current conditions and reasonable and supportable forecasts that affect collectability. The Company adopted the standard and its related amendments as of January 1, 2020. The Company has evaluated the impact of this ASU and concluded that the adoption of this standard did not have a significant impact on its consolidated financial statements. Reference Rate Reform In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The guidance provides optional practical expedients for applying U.S. GAAP to hedging relationships affected by reference rate reform. The guidance is applicable to the Company's debt agreements, hedging relationships, and other transactions that reference LIBOR. The Company adopted the standard and certain of its related amendments as of March 12, 2020. The adoption of this standard will help ease the burden that the Company may face at the time of transition from certain reference rates, specifically LIBOR, which is the predominant reference rate in many of the Company’s debt agreements and hedging relationships. The practical expedients applicable to the Company are as follows: (1) contract modifications due to reference rate reform can be treated as continuations of the existing contract and potential changes to interest rate risk can be disregarded when asserting the probability of the forecasted hedged transactions; (2) hedge accounting can continue to be used for hedging relationships where critical terms change due to reference rate reform; and (3) effectiveness assessments can be performed in ways that disregard certain mismatches due to reference rate reform. The Company concluded that the adoption of this standard will not have a significant impact on our consolidated financial statements.

The fair value of total debt outstanding was $6,536.5 million and $6,747.8 million as of December 31, 2020 and December 31, 2019, respectively, and was measured using Level 2 inputs. As of December 31, 2020, the maximum borrowing levels for the asset-backed securitization ("ABS") warehouse and the revolving credit facilities are $1,125.0 million and $1,560.0 million, respectively. These facilities are governed by borrowing bases that limit borrowing capacity to an established percentage of relevant assets. As of December 31, 2020, the availability under these credit facilities without adding additional container assets to the borrowing base was approximately $711.6 million. The Company is subject to certain financial covenants under its debt agreements. The agreements remain the obligations of the respective subsidiaries, and all related debt covenants are calculated at the subsidiary level. As of December 31, 2020 and December 31, 2019, the Company was in compliance with all financial covenants in accordance with the terms of its debt agreements. The Company hedges the risks associated with fluctuations in interest rates on a portion of its floating-rate debt by entering into interest rate swap agreements that convert a portion of its floating-rate debt to a fixed rate basis, thus reducing the impact of interest rate changes on future interest expense. The following table summarizes the Company's outstanding fixed-rate and floating-rate debt as of December 31, 2020 (in thousands): Balance Outstanding Contractual Weighted Avg Interest Rate Maturity Range Weighted Avg Remaining Term From To Excluding impact of derivative instruments: Fixed-rate debt $3,919,200 3.19% Jun 2021 May 2030 4.2 years Floating-rate debt $2,525,725 1.73% Aug 2023 Nov 2027 3.2 years Including impact of derivative instruments: Fixed-rate debt $3,919,200 3.19% Hedged floating-rate debt 1,709,975 3.59% Total fixed and hedged debt 5,629,175 3.31% Unhedged floating-rate debt 815,750 1.73% Total $6,444,925 3.11% On January 31, 2020, the Company paid $7.5 million to exercise the early purchase option on a finance lease obligation. On September 21, 2020, the Company extinguished a term loan and paid the outstanding balance of $264.9 million. As a result, the Company wrote off $0.3 million of debt related costs. The Company issued the following ABS fixed-rate series: Date Total Offering Contractual Weighted Avg Interest Rate Expected Maturity August 26, 2020 $312.9 Million 2.17% Feb 2028 September 21, 2020 $1,365.8 Million 2.19% May 2030 September 21, 2020 $634.4 Million 2.13% May 2029 Concurrently with the issuance of these ABS series, the Company called three existing ABS series that had an outstanding principal amount of $1,783.1 million. As a result, the Company paid a prepayment penalty of $1.8 million and wrote off $22.3 million of debt related costs. On November 13, 2020, the Company amended an existing $800.0 million ABS warehouse facility which increased its borrowing capacity from $800.0 million to $1,025.0 million, increased its interest rate to one-month LIBOR plus 1.85%, and extended the maturity date to November 15, 2027. As a result of this transaction, the company wrote off $0.3 million of debt related costs. On December 21, 2020, the Company exercised an option which increased the total commitment to $1,125.0 million. Institutional Notes In accordance with the Company's institutional note agreements, interest payments are due semi-annually. Institutional note maturities typically range from 7 - 12 years, with level principal payments due annually following an interest-only period. The institutional notes are pre-payable (in whole or in part) at the Company's option at any time, subject to certain provisions in the note agreements, including the payment of a make-whole premium in respect to such prepayment. These facilities provide for an advance rate against the net book values of designated eligible equipment. Asset-Backed Securitization Term Notes Under the Company's ABS facilities, indirect wholly-owned subsidiaries of the Company issue ABS notes. These subsidiaries are intended to be bankruptcy remote so that such assets are not available to creditors of the Company or its affiliates until and unless the related secured borrowings have been fully discharged. These transactions do not meet accounting requirements for sales treatment and are recorded as secured borrowings. The Company's borrowings under the ABS facilities amortize in monthly installments, typically in level payments over five or more years. These facilities provide for an advance rate against the net book values of designated eligible equipment. The net book values for purposes of calculating eligible equipment is determined according to the related debt agreement and may be different than those calculated per U.S. GAAP. The Company is required to maintain restricted cash balances on deposit in designated bank accounts equal to three to nine months of interest expense depending on the terms of each facility. Term Loan Facility The term loan facility amortizes in quarterly installments. This facility provides for an advance rate against the net book values of designated eligible equipment. Asset-Backed Securitization Warehouse Under the Company's asset-backed warehouse facility, an indirect wholly-owned subsidiary of the Company issues ABS notes. This subsidiary is intended to be bankruptcy remote so that such assets are not available to creditors of the Company or its affiliates until and unless the related secured borrowings have been fully discharged. These transactions do not meet accounting requirements for sales treatment and are recorded as secured borrowings. The Company's asset-backed warehouse facility has a borrowing capacity of $1,125.0 million that is available on a revolving basis until November 13, 2023, paying interest at LIBOR plus 1.85%, after which any borrowings will convert to term notes with a maturity date of November 15, 2027, paying interest at LIBOR plus 2.85%. During the revolving period, the borrowing capacity under this facility is determined by applying an advance rate against the net book values of designated eligible equipment. The net book values for purposes of calculating eligible equipment are determined according to the related debt agreement and may be different than those calculated per U.S. GAAP. The Company is required to maintain restricted cash balances on deposit in designated bank accounts equal to three months of interest expense. Revolving Credit Facilities The revolving credit facilities have a maximum borrowing capacity of $1,560.0 million. These facilities provide for an advance rate against the net book values of designated eligible equipment. Debt Maturities At December 31, 2020, the Company's scheduled principal repayments and maturities, excluding finance lease obligations, were as follows (in thousands): Years ending December 31, 2021 $ 659,109 2022 716,152 2023 1,533,307 2024 1,384,416 2025 395,078 2026 and thereafter 1,739,559 Total $ 6,427,621 Finance Lease Obligations Certain containers are leased with a financial institution.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments Interest Rate Swaps / Caps The Company enters into derivative agreements to manage interest rate risk exposure. Interest rate swap agreements are utilized to limit the Company's exposure to interest rate risk by converting a portion of its floating-rate debt to a fixed rate basis, thus reducing the impact of interest rate changes on future interest expense. The Company also utilized forward starting interest rate swap agreements to reduce the impact of interest rate changes on anticipated future fixed-rate debt issuances. Interest rate swaps involve the receipt of floating-rate amounts in exchange for fixed rate interest payments over the lives of the agreements without an exchange of the underlying principal amounts. The Company also utilizes interest rate cap agreements to manage interest rate risk exposure. Interest rate cap agreements place a ceiling on the Company's exposure to rising interest rates. The counterparties to these agreements are highly rated financial institutions. In the unlikely event that the counterparties fail to meet the terms of these agreements, the Company's exposure is limited to the interest rate differential on the notional amount at each monthly settlement period over the life of the agreements. The Company does not anticipate any non-performance by the counterparties. Certain assets of the Company's subsidiaries are pledged as collateral for various credit facilities and the amounts payable under certain agreements. During the year ended December 31, 2020, the Company entered into the following hedging instruments: Derivative Instrument Date Effective Notional Amount Fixed Leg (Pay) Interest Rate Indexed To Scheduled Maturity Interest rate swap April 20, 2020 $125.0 million 0.35% 1 month LIBOR April 20, 2024 Interest rate cap November 13, 2020 $200.0 million n/a 1 month LIBOR November 13, 2023 Forward starting interest rate swap February 22, 2021 $150.0 million 0.55% 1 month LIBOR August 20, 2028 (1) Forward starting interest rate swap February 22, 2021 $150.0 million 0.55% 1 month LIBOR August 20, 2028 (1) Forward starting interest rate swap May 28, 2021 $150.0 million 0.60% 1 month LIBOR November 30, 2028 (2) Forward starting interest rate swap May 28, 2021 $150.0 million 0.59% 1 month LIBOR November 30, 2028 (2) (1) Mandatory termination date of March 22, 2021, which aligns with the forecasted transaction. (2) Mandatory termination date of June 30, 2021, which aligns with the forecasted transaction. During the year ended December 31, 2020, the Company canceled the following interest rate swap and cap: Derivative Instrument Date Canceled Notional Amount Funds Paid Interest rate swap November 13, 2020 $71.3 million $5.1 million Interest rate cap November 13, 2020 $200.0 million n/a As of December 31, 2020, the Company had interest rate swap and cap agreements in place to fix or limit the floating interest rates on a portion of the borrowings under its debt facilities summarized below: Derivatives Notional Weighted Average Cap Rate Weighted Average Interest Rate Swap (1) $1,710.0 million 2.01% n/a 5.0 years Interest Rate Cap $200.0 million n/a 5.50% 2.9 years (1) The impact of forward starting swaps will increase total notional amount by $950.0 million and increase the weighted average remaining term to 6.0 years. Unrealized losses of $30.3 million related to interest rate swap and cap agreements included in accumulated other comprehensive income (loss) are expected to be recognized in Interest and debt expense over the next twelve months. The following table summarizes the impact of derivative instruments on the consolidated statements of operations and the consolidated statements of comprehensive income on a pretax basis (in thousands): Financial statement caption Year Ended December 31, Derivative instrument 2020 2019 2018 Non-designated derivative instruments Realized (gain) loss on derivative instruments, net $ (224) $ (2,237) $ (2,072) Non-designated derivative instruments Unrealized (gain) loss on derivative instruments, net 286 3,107 430 Designated derivative instruments Interest and debt (income) expense 23,071 (6,048) (6,780) Designated derivative instruments Comprehensive loss 134,051 48,653 2,119 Fair Value of Derivative Instruments The Company has elected to use the income approach to value its interest rate swap and cap agreements, using Level 2 market expectations at the measurement date and standard valuation techniques to convert future values to a single discounted present value. The Level 2 inputs for the interest rate swap and cap valuations are inputs other than quoted prices that are observable for the asset or liability (specifically LIBOR and swap rates and credit risk at commonly quoted intervals). In response to the expected phase out of LIBOR, the Company continues to work with its counterparties to identify an alternative reference rate. Substantially all of the Company's debt agreements already include transition language, and the Company also adopted various practical expedients which will facilitate the transition. The Company presents the fair value of derivative financial instruments on a gross basis as a separate line item on the consolidated balance sheet. The fair value of non-designated derivative instruments included in asset derivatives was $0.3 million at December 31, 2019. The Company has no material non-designated instruments as of December 31, 2020.

Equity [Abstract]
Share-Based Compensation	Share-Based Compensation On July 8, 2016, the Company's 2016 Equity Incentive Plan ("2016 Equity Plan") became effective. The 2016 Equity Plan provides for the granting of service-based and performance-based restricted shares to executives, employees and directors. The maximum aggregate number of shares that may be issued under the 2016 Equity Plan is 5,000,000 common shares. Any awards issued under the 2016 Equity Plan that are forfeited by the participant, will become available for future grant under the 2016 Equity Plan. The following table summarizes the Company's restricted share activity for the year ended December 31, 2020: Number of Shares Weighted Average Fair Value Non-vested balance at December 31, 2019 561,212 $ 31.84 Shares granted 283,161 36.44 Shares vested (1) (204,497) 38.19 Shares forfeited (2,073) 35.70 Non-vested balance at December 31, 2020 637,803 $ 35.78 (1) Plan participants tendered 53,609 common shares to satisfy income tax withholding obligations.

Under the repurchase program, shares may be purchased in the open market or privately negotiated transactions, and may include transactions pursuant to a repurchase plan administered in accordance with Rules 10b5-1 and 10b-18 under the Securities Exchange Act of 1934, as amended. Purchases may be made from time to time at the Company's discretion and the timing and amount of any share repurchases will be determined based on share price, market conditions, legal requirements, and other factors. The repurchase program does not obligate the Company to acquire any particular amount of common shares, and the Company may suspend or discontinue the repurchase program at any time. During the year ended December 31, 2020, the Company repurchased 5,129,981 common shares at an average price per-share of $30.85 and a total cost of $158.3 million. During the year ended December 31, 2019, the Company repurchased 6,918,197 common shares at an average price per-share of $31.82 and a total cost of $220.1 million.

The net proceeds were used for general corporate purposes, including the purchase of containers, the repurchase of outstanding common shares, the payment of dividends, and the repayment or repurchase of outstanding indebtedness. Each Series of preferred shares may be redeemed at the Company's option, at any time after approximately five years from original issuance, in whole or in part at a redemption price, which is equal to the issue price, of $25.00 per share plus an amount equal to all accumulated and unpaid dividends, whether or not declared. The Company may also redeem each Series of preferred shares prior to the lapse of the five year period upon the occurrence of certain events as described in each agreement, such as transactions that either transfer ownership of substantially all assets to a single entity or establish a majority voting interest by a single entity, and cause a downgrade or withdrawal of rating by the rating agency within 60 days of the event. If the Company does not elect to redeem each Series, holders of preferred shares may have the right to convert their preferred shares into common shares. Holders of preferred shares generally have no voting rights. If the Company fails to pay dividends for six or more quarterly periods (whether or not consecutive), holders will be entitled to elect two additional directors to the Board of Directors and the size of the Board of Directors will be increased to accommodate such election. Such right to elect two directors will continue until such time as there are no accumulated and unpaid dividends in arrears. Dividends Dividends on shares of each Series are cumulative from the date of original issue and will be payable quarterly in arrears on the 15th day of March, June, September and December of each year, when, as and if declared by the Company's Board of Directors. Dividends will be payable equal to the stated rate per annum of the $25.00 liquidation preference per share. The Series rank senior to the Company's common shares with respect to dividend rights and rights upon the Company's liquidation, dissolution or winding up, whether voluntary or involuntary.

Segment Reporting [Abstract]
Segment and Geographic Information	Segment and Geographic Information Segment Information The Company operates its business in one industry, intermodal transportation equipment, and has two operating segments which also represent its reporting segments: • Equipment leasing - the Company owns, leases and ultimately disposes of containers and chassis from its lease fleet. • Equipment trading - the Company purchases containers from shipping line customers, and other sellers of containers, and resells these containers to container retailers and users of containers for storage or one-way shipment.

(2) Represents cash disbursements for purchases of leasing equipment and investments in finance lease as reflected in the consolidated statements of cash flows for the periods indicated, but excludes cash flows associated with the purchase of equipment held for resale. (3) Equipment leasing segment includes gain on sale of an office building of $21.0 million for the year ended December 31, 2018. There are no intercompany revenues or expenses between segments. Certain administrative expenses have been allocated between segments based on an estimate of services provided to each segment. A portion of the Company's equipment purchased for resale may be leased for a period of time and is reflected as leasing equipment as opposed to equipment held for sale and the cash flows associated with these transactions are reflected as purchases of leasing equipment and proceeds from the sale of equipment in investing activities in the Company's consolidated statements of cash flows. Geographic Segment Information The Company generates the majority of its leasing revenues from international containers which are deployed by its customers in a wide variety of global trade routes. The majority of the Company's leasing related revenue is denominated in U.S. dollars. The following table summarizes the geographic allocation of equipment leasing revenues for the years ended December 31, 2020, 2019, and 2018 based on customers' primary domicile (in thousands): Year Ended December 31, 2020 2019 2018 Total equipment leasing revenues: Asia $ 471,820 $ 534,529 $ 553,928 Europe 685,906 654,683 630,031 Americas 105,643 118,259 124,885 Bermuda 1,820 2,182 2,988 Other International 42,718 37,616 38,471 Total $ 1,307,907 $ 1,347,269 $ 1,350,303 Since the majority of the Company's containers are used internationally, where no one container is domiciled in one particular place for a prolonged period of time, all of the Company's long-lived assets are considered to be international.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company is a Bermuda exempted company. Bermuda does not impose a corporate income tax. The Company is subject to taxation in certain foreign jurisdictions on a portion of its income attributable to such jurisdictions. The two main subsidiaries of Triton are TCIL and TAL. TCIL is a Bermuda exempted company and therefore no income tax is imposed. However, a portion of TCIL's income is subject to taxation in the U.S. TAL is a U.S. company and therefore is subject to taxation in the U.S. The following table sets forth the total income taxes for the periods indicated (in thousands): December 31, December 31, 2019 December 31, 2018 Current taxes: Bermuda $ — $ — $ — U.S. 2,518 (637) 3,164 Foreign 60 1,166 1,072 $ 2,578 $ 529 $ 4,236 Deferred taxes: Bermuda $ — $ — $ — U.S. 35,628 26,843 67,136 Foreign 34 179 (731) 35,662 27,022 66,405 Total income taxes $ 38,240 $ 27,551 $ 70,641 The following table sets forth the components of income (loss) before income taxes (in thousands): December 31, 2020 December 31, 2019 December 31, 2018 Bermuda sources $ 200,453 $ 241,985 $ 128,905 U.S. sources 166,031 135,758 288,386 Foreign sources 1,535 3,087 10,022 Income (loss) before income taxes $ 368,019 $ 380,830 $ 427,313 The following table sets forth the difference between the Bermuda statutory income tax rate and the effective tax rate on the consolidated statements of operations for the periods indicated below: December 31, 2020 December 31, 2019 December 31, 2018 Bermuda tax rate — % — % — % Change in enacted tax act 0.65 % — % 1.02 % U.S. income taxed at other than the statutory rate 9.80 % 7.85 % 14.67 % Effect of uncertain tax positions (0.12) % 0.17 % 0.07 % Foreign income taxed at other than the statutory rate 0.14 % 0.14 % 0.18 % Effect of permanent differences 0.19 % 0.12 % 0.28 % Other discrete items (0.27) % (1.05) % 0.31 % Effective income tax rate 10.39 % 7.23 % 16.53 % The following table sets forth the components of deferred income tax assets and liabilities (in thousands): December 31, 2020 December 31, 2019 Deferred income tax assets: Net operating loss carryforwards $ 22,924 $ 71,138 Allowance for losses 257 141 Derivative instruments 11,268 4,899 Deferred income 382 395 Accrued liabilities and other payables 5,713 3,118 Total gross deferred tax assets 40,544 79,691 Less: Valuation allowance — — Net deferred tax assets $ 40,544 $ 79,691 Deferred income tax liabilities: Accelerated depreciation $ 331,954 $ 353,991 Goodwill and other intangible amortization 3,841 3,775 Derivative instruments — 105 Deferred income 6,244 11,034 Deferred partnership income (loss) 25,856 11,786 Other 80 317 Total gross deferred tax liability 367,975 381,008 Net deferred income tax liability $ 327,431 $ 301,317 The Company has not recorded a valuation allowance for deferred tax assets as of December 31, 2020 and December 31, 2019. In assessing the potential future realization of deferred tax assets, management considers whether it is more-likely-than-not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. The Company considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods during which the deferred tax assets are deductible, the Company believes it is more-likely-than-not that the Company will realize the benefits of these deductible differences at December 31, 2020. Certain income taxes on unremitted earnings have not been reflected on the consolidated financial statements because such earnings are intended to be permanently reinvested in those jurisdictions. Such earnings and related income taxes are estimated to be approximately $66.0 million and $19.0 million, respectively, at December 31, 2020. The Tax Cuts and Jobs Act includes a tax on "global intangible low-taxed income" ("GILTI"), which taxes U.S shareholders on certain income earned by foreign subsidiaries. The Company has made an accounting policy election to account for the tax effects of the GILTI tax in the income tax provision in future periods as the tax arises. On March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief and Economic Security Act ("CARES Act"). The enactment of the CARES Act does not result in any material adjustments to the Company’s provision for income taxes. Net operating loss carryforwards for U.S. federal income tax purposes of $103.0 million at year end December 31, 2020 are available to offset future U.S. taxable income. Of the total net operating loss carryforwards, $51.0 million are available to offset future U.S. taxable income from 2021 through 2037. The remaining $52.0 million are carried forward indefinitely but subject to a limitation of 80% of the year's U.S. taxable income. The Company files income tax returns in several jurisdictions including the U.S. and certain U.S. states. The following table sets forth the unrecognized tax benefit amounts (in thousands): December 31, 2020 December 31, 2019 Beginning balance at January 1 $ 958 $ 8,590 Increase (decrease) related to tax positions — (7,248) Lapse of statute of limitations (318) (333) Foreign exchange adjustment 10 (51) Ending balance at December 31 $ 650 $ 958 It is reasonably possible that the total amount of unrecognized tax benefits as of December 31, 2020 will decrease by $0.3 million within the next twelve months due to statute of limitations lapses. This reduction will impact income tax expense when recognized. The tax years 2017 through 2020 remain subject to examination by major tax jurisdictions. The Company accrues interest and penalties related to income taxes in the provision for income taxes. The following table summarizes interest and penalty expense (in thousands): December 31, 2020 December 31, 2019 December 31, 2018 Interest expense (benefit) $ (51) $ 193 $ 98 Penalty expense (benefit) $ (93) $ (115) $ (158) The following table summarizes the components of income taxes payable included in Accounts payable and other accrued expenses on the consolidated balance sheets (in thousands): December 31, 2020 December 31, 2019 Corporate income taxes payable $ 323 $ 29 Unrecognized tax benefits 650 958 Interest accrued 164 215 Penalties 194 287 Income taxes payable $ 1,331 $ 1,489

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2020
Accounting Policies [Abstract]
Principles of Consolidation	Principles of ConsolidationThe consolidated financial statements include the accounts of the Company and subsidiaries in which it has a controlling interest, and variable interest entities of which the Company is the primary beneficiary. The equity method of accounting is applied when the Company does not have a controlling interest in an entity but exerts significant influence over the entity. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of EstimatesThe preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities in the financial statements. Such estimates include, but are not limited to, the Company's estimates in connection with leasing equipment, including residual values and depreciable lives, values of assets held for sale and other long lived assets, provision for income tax, allowance for doubtful accounts, share-based compensation, goodwill and intangible assets. Actual results could differ from those estimates.
Segment Reporting	Segment ReportingThe Company conducts its business activities in one industry, intermodal transportation equipment, and has two reporting segments, Equipment leasing and Equipment trading. The Company also segregates total equipment leasing revenues and total equipment trading revenues by geographic location based upon the primary domicile of the Company's customers.
Concentration of Credit Risk	The Company's equipment leases and trade receivables subject it to potential credit risk. The Company extends credit to its customers based upon an evaluation of each customer's financial condition and credit history. Evaluations of the financial condition and associated credit risk of customers are performed on an ongoing basisOther financial instruments that are exposed to concentration of credit risk are cash and cash equivalents, and restricted cash balances. Cash and cash equivalents, and restricted cash are held with financial institutions of high quality. Balances may exceed the amount of insurance provided on such deposits.
Fair Value Measurements	Fair Value Measurements Fair value represents the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The determination of fair value may require an entity to make significant judgments or develop assumptions about market participants to reflect risks specific to the asset being valued. The Company uses the following fair value hierarchy when selecting inputs for its valuation techniques, with the highest priority given to Level 1: • Level 1—quoted prices (unadjusted) in active markets for identical assets or liabilities; • Level 2—inputs other than quoted prices included within Level 1 that are either directly or indirectly observable; and • Level 3—unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its own assumptions about the assumptions that market participants would use in pricing. Cash and cash equivalents, restricted cash, accounts receivable, equipment purchases payable and accounts payable carrying amounts approximate fair values because of the short-term nature of these instruments. The Company's other financial and non-financial assets, which include leasing equipment, net investment in finance leases, intangible assets and goodwill, are not required to be measured at fair value on a recurring basis. However, if certain triggering events occur, or if an annual impairment test is required, and the Company determines that these other financial and non-financial assets are impaired after completing an evaluation, these assets would be written down to their fair value.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of all cash balances and highly liquid investments having original maturities of three months or less at the time of purchase.
Restricted Cash	Restricted Cash The Company's restricted cash relates to amounts held at financial institutions pursuant to certain debt arrangements. The restricted cash balances represent cash proceeds collected and required to be used to pay debt service and other related expenses.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts The Company's allowance for doubtful accounts is estimated based upon a review of the collectibility of its receivables. This review is based on the risk profile of the receivables, credit quality indicators such as the level of past-due amounts and economic conditions. Generally, the Company does not require collateral on accounts receivable balances. An account is considered past due when a payment has not been received in accordance with the contractual terms. Changes in economic conditions or other events may necessitate additions or deductions to the allowance for doubtful accounts. The allowance for doubtful accounts is intended to provide for losses in the receivables, and requires the application of estimates and judgments as to the outcome of collection efforts, among other things. The Company believes its allowance for doubtful accounts is adequate to provide for credit losses inherent in its existing receivables. For our net investment in finance leases and accounts receivable for sales of equipment, the Company measures expected credit loss by evaluating the overall credit quality of its customers. Expected credit losses for these financial assets are estimated using historical experience which includes multiple economic cycles, customer payment history, management's assessment of the customer's financial condition, and consideration of current conditions and reasonable forecasts.
Net Investment in Finance Leases	Net Investment in Finance Leases The Company has entered into various lease agreements that qualify as sales-type leases. These leases are usually long-term in nature, ranging for a period of three to twelve years, and typically include an option to purchase the equipment at the end of the lease term for a nominal price that the Company deems reasonably certain to be exercised. At the inception of a sales-type lease, a net investment is recorded based on the gross investment (representing the total future minimum lease payments plus the estimated residual value), net of unearned income. Unearned income represents the excess of the gross investment over the fair value of the leased equipment at lease commencement. Any gain or loss is recognized at commencement and recorded in Net gain on sale of leasing equipment.
Leasing Equipment	Leasing Equipment The Company purchases new equipment from equipment manufacturers for the purpose of leasing such equipment to customers. The Company also purchases used equipment with the intention of selling such equipment in one or more years from the date of purchase. Leasing equipment is recorded at cost and depreciated to an estimated residual value on a straight-line basis over the estimated useful lives. Capitalized costs for new container rental equipment include the manufactured cost of the container, inspection, delivery, and associated costs incurred in moving the container from the manufacturer to the initial on-hire location of such container. Repair and maintenance costs that do not extend the lives of the container rental equipment are charged to direct operating expenses at the time the costs are incurred. The estimated useful lives and residual values of the Company's leasing equipment are based on historical disposal experience and the Company's expectations for future used container sale prices. The Company evaluates estimates used in its depreciation policy on a regular basis to determine whether changes have taken place that would suggest that a change in its depreciation estimates for useful lives or the assigned residual values of its equipment is warranted. For 2020, the Company completed its annual depreciation policy assessment during the fourth quarter and concluded no change was necessary. The estimated useful lives and residual values for each major equipment type for the periods indicated below were as follows: As of December 31, 2020 and 2019 Equipment Type Depreciable Life Residual Value Dry containers 20-foot dry container 13 years $ 1,000 40-foot dry container 13 years $ 1,200 40-foot high cube dry container 13 years $ 1,400 Refrigerated containers 20-foot refrigerated container 12 years $ 2,350 40-foot high cube refrigerated container 12 years $ 3,350 Special containers 40-foot flat rack container 16 years $ 1,700 40-foot open top container 16 years $ 2,300 Tank containers 20 years $ 3,000 Chassis 20 years $ 1,200 Depreciation on leasing equipment commences on the date of initial on-hire. For leasing equipment purchased for resale that may be leased for a period of time, the Company adjusts its estimates for remaining useful life and residual values based on current conditions in the sales market for older containers and the Company's expectations for how long the equipment will remain on-hire to the current lessee. The net book value of the Company's leasing equipment by equipment type as of the dates indicated was (in thousands): December 31, 2020 December 31, 2019 Dry container $ 6,589,960 $ 6,308,038 Refrigerated container 1,483,820 1,520,747 Special container 307,765 321,099 Tank container 97,982 101,677 Chassis 151,169 140,986 Total $ 8,630,696 $ 8,392,547
Valuation of Leasing Equipment	Valuation of Leasing Equipment Leasing equipment is evaluated for impairment whenever events or changes in circumstances indicate that its carrying value may not be recoverable. Recoverability of an asset to be held and used is measured by a comparison of the carrying value to its estimated undiscounted future cash flows expected to be generated by the asset. If the carrying value of an asset exceeds its estimated undiscounted future cash flows, an impairment charge is recognized in the amount by which the carrying value of the asset exceeds the fair value of the asset. Key indicators of impairment on leasing equipment include, among other factors, a sustained decrease in operating profitability, a sustained decrease in utilization, or indications of technological obsolescence. When testing for impairment, leasing equipment is generally grouped by equipment type, and is tested separately from other groups of assets and liabilities. Some of the significant estimates and assumptions used to determine future undiscounted cash flows and the measurement for impairment are the remaining useful life, expected utilization, expected future lease rates and expected disposal prices of the equipment. The Company considers the assumptions on expected utilization and the remaining useful life to have the greatest impact on its estimate of future undiscounted cash flows. These estimates are principally based on the Company's historical experience and management's judgment of market conditions. The Company did not record any impairment charges related to leasing equipment for the years ended December 31, 2020, 2019, and 2018.
Equipment Held for Sale	Equipment Held for Sale When leasing equipment is returned off lease, the Company makes a determination of whether to repair and re-lease the equipment or sell the equipment. At the time the Company determines that equipment will be sold, it reclassifies the appropriate amounts previously recorded as leasing equipment to equipment held for sale. Equipment held for sale is recorded at the lower of its estimated fair value less costs to sell or carrying value at the time identified for sale. Depreciation expense on equipment held for sale is halted and disposals generally occur within 90 days. Initial write downs of equipment held for sale to fair value are recorded as an impairment charge and are included in net gain on sale of leasing equipment. Subsequent increases or decreases to the fair value of those assets are recorded as adjustments to the carrying value of the equipment held for sale, however, any such adjustments may not exceed the respective equipment's carrying value at the time it was initially classified as held for sale. Realized gains and losses resulting from the sale of equipment held for sale are recorded in Net gain on sale of leasing equipment, and cash flows associated with the disposal of equipment held for sale are classified as cash flows from investing activities.
Operating Leases	Operating Leases The Company leases office space and office equipment and evaluates whether these leases are classified as operating or financing at the inception of the lease. The classification is based on certain assumptions that require judgment, such as the asset's fair value, the asset's estimated residual value, the interest rate implicit in the lease, and the asset's economic useful life. For operating leases, the Company records a lease liability based on the present value of the remaining minimum payments and a corresponding right-of-use ("ROU") asset. The Company uses its estimated incremental borrowing rate at the commencement date to determine the present value of lease payments. The benefits of lease incentives, including rent-free or reduced rent periods, and the cost of future rent escalations are recognized on a straight-line basis over the term of the lease. A lease liability and a corresponding ROU asset are not recognized when, at the commencement date of the lease, the term is 12 months or less.
Property, Plant and Equipment	Property, Furniture and Equipment Costs of major additions of property, furniture, equipment and improvements are capitalized and are included in other assets on the consolidated balance sheets. The original cost is depreciated on a straight-line basis over the estimated useful lives of such property, furniture and equipment. Leasehold improvements are amortized on a straight-line basis over the shorter of the lease term or the estimated useful lives of the leased assets. Other fixed assets, which consist primarily of computer software and hardware, are recorded at cost and amortized on a straight-line basis over their respective estimated useful lives, which range from three to seven years. Expenditures for maintenance and repairs are expensed as they are incurred.
Goodwill	Goodwill Goodwill is tested for impairment at least annually on October 31st of each fiscal year or more frequently if events occur or circumstances indicate that the fair value of a reporting unit may be below its carrying value. Goodwill has been allocated to the Company's reporting units, which are the same as its reporting segments. In evaluating goodwill for impairment, the Company has the option to first assess qualitative factors to determine whether further impairment testing is necessary. Among the relevant events and circumstances that affect the fair value of reporting units, the Company considers individual factors such as macroeconomic conditions, changes in its industry and the markets in which the Company operates, as well as its reporting units' historical and expected future financial performance. If, after assessing the totality of events or circumstances, the Company determines it is more-likely-than-not that the fair value of a reporting unit is greater than its carrying amount, then the quantitative goodwill impairment test is unnecessary. The quantitative goodwill impairment test compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount of the reporting unit is less than its fair value, no impairment exists. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit.
Intangible Assets	Intangible Assets Intangible assets with finite useful lives such as acquired lease intangibles are initially recorded at fair value and are amortized over their respective estimated useful lives and subsequently reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. The Company has not recorded any impairment charges related to intangible assets for the years ended December 31, 2020, 2019, and 2018.
Revenue Recognition	Revenue Recognition Operating Leases with Customers The Company enters into long-term leases and service leases with ocean carriers, principally as lessor in operating leases, for marine cargo equipment. Long-term leases provide customers with specified equipment for a specified term. The Company's leasing revenues are based upon the number of equipment units leased, the applicable per diem rate and the length of the lease. Long-term leases typically have initial contractual terms ranging from three to eight or more years. Revenues are recognized on a straight-line basis over the life of the respective lease. Revenue from advance billings are deferred and recognized in the period earned. Service leases do not specify the exact number of equipment units to be leased or the term that each unit will remain on-hire, but allow the lessee to pick-up and drop-off units at various locations specified in the lease agreement. Under a service lease, rental revenue is based on the number of equipment units on-hire for a given period. Revenue from customers considered to be non-performing is deferred and recognized when the amounts are received. The Company recognizes billings to customers for damages and certain other operating costs as leasing revenue when earned based on the terms of the contractual agreements with the customer. Finance Leases with Customers The Company enters into finance leases as lessor for some of the equipment in its fleet. At the inception of the lease, the Company records the total future minimum lease payments plus the estimated residual value, net of executory costs, if any. The net investment in finance leases represents the receivables due from lessees, net of unearned income and amounts previously billed, which are included in accounts receivable. Unearned income, which also includes any initial direct costs, is recognized on a constant yield basis over the lease term and is recorded as leasing revenue. The Company's finance leases are usually long-term in nature and typically include an option to purchase the equipment at the end of the lease term for a nominal price that the Company deems reasonably certain to be exercised. Equipment Trading Revenues and Expenses
Direct Operating Expenses	Direct Operating Expenses Direct operating expenses are directly related to the Company's equipment under and available for lease. These expenses primarily consist of the Company's costs to repair and maintain the equipment, to reposition the equipment and to store the equipment when it is not on lease. These costs are recognized when incurred. Certain positioning costs may be capitalized when incurred to place new equipment on an initial lease.
Debt Costs	Debt CostsDebt costs represent the fees incurred in connection with debt obligation arrangements. These costs are capitalized and amortized using the effective interest method or on a straight-line basis over the term of the related obligation, depending on the type of debt obligation to which they relate. Unamortized debt costs may be written off when the related debt obligations are refinanced or extinguished prior to maturity.
Derivative Instruments	Derivative Instruments The Company uses derivatives in the management of its interest rate exposure on its long-term borrowings. The Company records derivative instruments on its balance sheet at fair value and establishes criteria for both the designation and effectiveness of hedging activities. The Company has entered into interest rate swap agreements with certain financial institutions. The interest rate swap agreements require the Company to make payments to counterparties at fixed rates in return for receipts based upon variable rates indexed to the London Interbank Offered Rate ("LIBOR") or its replacement rate. Derivative instruments are designated or non-designated for hedge accounting purposes. The fair value of the derivative instruments is measured at each balance sheet date and is reflected on a gross basis on the consolidated balance sheets. The change in fair value of the derivative instruments designated as a cash flow hedge are recorded on the consolidated balance sheets in accumulated other comprehensive income (loss) and are re-classified to interest and debt expense when the hedged interest payments are recognized. The change in fair value of non-designated derivative instruments is recorded in the consolidated statements of operations as unrealized loss (gain) on derivative instruments, net and are reclassified to realized loss
Income Taxes	Income Taxes The Company uses the liability method of accounting for income taxes, which requires recognition of deferred tax assets and liabilities based on the expected future tax consequences of temporary differences that currently exist between the tax basis and financial reporting basis of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Any change in the tax rate which has an effect on deferred tax assets and liabilities is recognized as an increase or decrease to income in the period that includes the enactment date of the law that resulted in the change in tax rate. The Company recognizes the effect of income tax positions which are more-likely-than-not of being sustained. If a position does not meet the more-likely-than-not criteria, the Company records a reserve against the tax position such that a tax benefit is recognized only in the amount that has a greater than 50% likelihood of being recognized. The full impact of any change in recognition or measurement of an uncertain tax position is reflected in the period in which such change occurs. Potential interest and penalties associated with such uncertain tax positions are recorded as a component of income tax expense.
Foreign Currency Translation and Remeasurement	Foreign Currency Translation and Remeasurement The Company uses the U.S. dollar as its reporting currency. The net assets and operations that are denominated in foreign currency and are subject to foreign currency translation included in the consolidated financial statements are attributable primarily to the Company's U.K. subsidiary. The accounts of this subsidiary have been converted at rates of exchange in effect at year end as to balance sheet accounts and at the annual weighted average exchange rates for the statements of operations accounts. The effects of changes in exchange rates in translating foreign subsidiaries' financial statements are included in shareholders' equity as accumulated other comprehensive (loss) income.
Stock-Based Compensation	Share-based Compensation The Company measures and recognizes share-based awards granted to employees based on the grant date fair value. Share-based awards may be subject to forfeiture if certain employment conditions are not met. The Company has elected to account for forfeitures as they occur. Time based awards are measured at the grant date and are recognized as compensation expense over the employee's requisite service period, generally the vesting period of the equity award, on a straight-line basis. Performance-based awards are recognized as compensation expense when satisfaction of the performance condition is considered probable. The Company also grants share-based awards to non-employee directors that vest immediately and are recognized as compensation expense based on the grant date fair value.
Earnings Per Share	Earnings Per Share Basic earnings per share is computed by dividing net income attributable to common shareholders by the weighted average number of common shares outstanding for the period. Any potential issuance of common shares, including those that are contingent and do not participate in dividends, are excluded from the weighted average number of common shares outstanding. Diluted earnings per share reflect the potential dilution that would occur if securities exercisable or convertible into common shares were exercised or converted into common shares, utilizing the treasury share method.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Standards Updates Measurement of Credit Losses on Financial Instruments In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) and subsequently issued amendments. The guidance affects the Company's net investment in finance leases and accounts receivable for sales of equipment. The standard requires the measurement of expected credit losses to be based on relevant information from past events, including historical experiences, current conditions and reasonable and supportable forecasts that affect collectability. The Company adopted the standard and its related amendments as of January 1, 2020. The Company has evaluated the impact of this ASU and concluded that the adoption of this standard did not have a significant impact on its consolidated financial statements. Reference Rate Reform In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The guidance provides optional practical expedients for applying U.S. GAAP to hedging relationships affected by reference rate reform. The guidance is applicable to the Company's debt agreements, hedging relationships, and other transactions that reference LIBOR. The Company adopted the standard and certain of its related amendments as of March 12, 2020. The adoption of this standard will help ease the burden that the Company may face at the time of transition from certain reference rates, specifically LIBOR, which is the predominant reference rate in many of the Company’s debt agreements and hedging relationships. The practical expedients applicable to the Company are as follows: (1) contract modifications due to reference rate reform can be treated as continuations of the existing contract and potential changes to interest rate risk can be disregarded when asserting the probability of the forecasted hedged transactions; (2) hedge accounting can continue to be used for hedging relationships where critical terms change due to reference rate reform; and (3) effectiveness assessments can be performed in ways that disregard certain mismatches due to reference rate reform. The Company concluded that the adoption of this standard will not have a significant impact on our consolidated financial statements.
