Description of the Business, Basis of Presentation and Recently Adopted Accounting Pronouncements [Text Block] | Note 1—Description of the Business and Significant Accounting Policies Description of the Business Triton International Limited ("Triton" or the "Company"), through its subsidiaries, leases intermodal transportation equipment, primarily maritime containers, and provides maritime container management services through a worldwide network of service subsidiaries, third-party depots and other facilities. The majority of the Company's business is derived from leasing its containers to shipping line customers through a variety of long-term and short-term contractual lease arrangements. The Company also sells containers from its equipment leasing fleet as well as containers specifically acquired for resale from third parties. The Company's registered office is located in Bermuda. On July 12, 2016, Triton Container International Limited ("TCIL") and TAL International Group, Inc. ("TAL") combined in an all-stock merger (the "Merger"). Under the terms of the transaction agreement, TCIL and TAL combined under a newly formed company, Triton. The consideration for the transaction was paid with Triton common shares. TAL stockholders received one Triton common share in exchange for each TAL common share and TCIL shareholders received approximately 0.8 Triton common shares for each TCIL common share. The fair value of the consideration, or the purchase price, was approximately $510.2 million . This amount was derived based on the fair value of the shares issued to TAL stockholders on July 12, 2016 when the closing share price was $15.28 per share. Basis of Presentation The unaudited consolidated financial statements and accompanying notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all information and footnotes required by GAAP for complete financial statements. The interim consolidated balance sheet as of September 30, 2017 , the consolidated statements of operations and comprehensive income for the three and nine months ended September 30, 2017 and 2016 , and the consolidated statements of cash flows for the nine months ended September 30, 2017 and 2016 are unaudited. The consolidated balance sheet as of December 31, 2016 , included herein, was derived from the audited financial statements as of that date, but does not include all disclosures required by GAAP. These unaudited interim financial statements have been prepared on a basis consistent with the Company’s annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments necessary to state fairly the Company’s financial position as of September 30, 2017 and its consolidated results of operations and comprehensive income for the three and nine months ended September 30, 2017 and 2016 , and its cash flows for the nine months ended September 30, 2017 and 2016 . The financial data and the other financial information disclosed in the notes to the financial statements related to these periods are also unaudited. The results of operations for the three and nine months ended September 30, 2017 are not necessarily indicative of the results to be expected for the fiscal year ending December 31, 2017 or for any other future annual or interim period. The unaudited consolidated financial statements include TAL’s results of operations after July 12, 2016, the Merger completion date. The consolidated financial statements presented for periods prior to the Merger represent the historical financial statements of TCIL, the accounting acquirer in the Merger. These financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto as of and for the year ended December 31, 2016 included in the Company’s Annual Report on Form 10-K which was filed with the SEC on March 17, 2017 . The unaudited consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Certain changes in presentation have been made to conform the prior period presentation to current period reporting. Note 1—Description of the Business and Significant Accounting Policies (continued) Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results could differ from those estimates. Such estimates include, but are not limited to, estimates in connection with purchase accounting, residual value, depreciable lives, value of assets held for sale, and estimates related to the bankruptcy of a lessee (including amounts for recoveries under insurance policies as described below). Lessee Bankruptcy in 2016 On August 31, 2016, Hanjin Shipping Co. ("Hanjin"), a lessee of the Company, filed for court protection and immediately began a liquidation process. At that time, the Company had approximately 87,000 container units on lease to Hanjin with a net book value of $243.3 million . The Company recorded a charge of $29.7 million during the third quarter ended September 30, 2016 comprised of bad debt expense and a charge for costs not expected to be recovered due to deductibles in our credit insurance policies. As of September 30, 2017 , the Company had gained control or negotiated the release of 93% of its containers previously leased to Hanjin of which approximately 82% are now leased to other customers or have been sold. The Company maintained credit insurance to cover the value of such containers that are unrecoverable, costs incurred to recover containers and a portion of lost lease revenue (limited up to six months or until a container is recovered, repaired, and available for re-lease) all subject to a deductible. The insurance policies did not cover its pre-default receivables. The Company has collected an advance partial payment from its insurance providers of $45 million . The Company currently believes that any further losses will be recoverable under the insurance policies, subject to deductible limits. Pro Forma Disclosure The following table provides the unaudited pro forma results of operations, which gives effect to the Merger as if it had occurred on January 1, 2016. The pro forma results of operations reflects adjustments (i) to leasing revenues for the amortization of the excess of the fair value of operating lease contracts over the current market rate (ii) to adjust depreciation and amortization expense resulting from the write-down of leasing equipment to fair value and (iii) to eliminate non-recurring charges that were incurred in connection with the transactions including acquisition-related share-based compensation, transaction costs related to legal, accounting, and other advisory fees, and transaction costs related to retention and benefit costs. The unaudited pro forma results do not include any anticipated synergies or other expected benefits of the Merger. The unaudited pro forma financial information presented below is not necessarily indicative of either future results of operations or results that might have been achieved had the Merger occurred as of January 1, 2016 (in thousands): Three months ended, September 30, 2016 Nine months ended September 30, 2016 Total leasing revenues $ 261,977 $ 815,256 Net (loss) income attributable to shareholders $ (2,377 ) $ 9,996 Concentration of Credit Risk The Company's equipment lease 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 two largest customers CMA CGM and Mediterranean Shipping Company, accounted for 19% and 14% , respectively, of the Company's lease billings during the nine months ended September 30, 2017 . Note 1—Description of the Business and Significant Accounting Policies (continued) New Accounting Pronouncements Recently Adopted Accounting Standards Updates In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. ASU No. 2016-09 ("ASU No. 2016-09") Compensation - Stock Compensation (Topic 718) Improvements to Employee Share-Based Payment Accounting . The guidance simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Under this ASU, all excess tax benefits and deficiencies related to employee share-based compensation will be recognized within the provision for income taxes rather than additional paid-in capital. The Company adopted the guidance on January 1, 2017 which resulted in the recognition of excess tax benefits for prior periods as a reduction in our Net deferred income tax liability account and an increase in accumulated earnings in the amount of $6.6 million . The Company has not recognized any excess tax benefits for the three and nine months ended September 30, 2017 . In addition, the adoption of this ASU had no impact on the consolidated financial statements with respect to forfeited awards since historically the Company’s forfeitures have been minimal and therefore had not estimated a forfeitures rate. Recently Issued Accounting Standards Updates In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) that replaces existing lease accounting guidance. Among other things, in the amendments in ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: • A lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and • A right-of-use asset, which is an asset that represents the lessee's right to use, or control the use of, a specified asset for the lease term. The accounting that will be applied by lessors under ASC 842 is largely unchanged from previous GAAP. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and ASC 606, Revenue from Contracts with Customers . The new lease guidance will become effective for the Company for periods beginning after December 15, 2018. The Company is currently evaluating the impact of this ASU on the consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606), amending previous updates regarding this topic. Leasing revenue recognition is specifically excluded from this ASU, and therefore, the new standard will only apply to equipment trading revenues and sales of leasing equipment. The Company expects the impact of adoption of this ASU to be minimal since the majority of its sales contracts are for containers and do not contain multiple elements. The effective date is interim periods beginning after December 15, 2017. The standard allows for either “full retrospective” adoption, meaning the standard is applied to all of the periods presented, or “modified retrospective” adoption, meaning the standard is applied only to the most current period presented in the financial statements. The Company plans to adopt the standard on its required effective date of January 1, 2018, using the modified retrospective approach. The Company does not expect the impact of this standard to be material to its consolidated financial statements and related disclosures. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments. The guidance affects trade receivables and net investments in leases. The guidance 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 new guidance will be effective for fiscal years and interim periods beginning after December 15, 2019 and early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Different components of the guidance require modified retrospective and/or prospective adoption. Based on the composition of the Company's receivables, current market conditions, and historical credit loss activity, the Company does not expect the adoption of this ASU to have a significant impact on the consolidated financial statements. Note 1—Description of the Business and Significant Accounting Policies (continued) In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Receipts and Cash Payments . The updated amendment provides guidance as to where certain cash flow items are presented, including, debt prepayment or debt extinguishment costs and proceeds from the settlement of insurance claims. The update to the standard is effective for the Company for periods beginning after December 15, 2017. The Company does not expect the adoption of this ASU to have a significant impact on the consolidated financial statements. In October 2016, the FASB issued ASU No. 2016-16, Accounting for Income Taxes (Topic 740) : Intra-Entity Asset Transfers of Assets Other than Inventory . The ASU eliminates the deferral of the tax effects of intra-entity asset transfers other than inventory. As a result, the tax expense from the intercompany sale of assets, other than inventory, and associated changes to deferred taxes will be recognized when the sale occurs even though the pre-tax effects of the transaction have not been recognized. The update to the standard is effective for the Company for periods beginning after December 15, 2017. The Company does not expect the adoption of this ASU to have a significant impact on its consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash . The amendments in this ASU require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. As a result, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments do not provide a definition of restricted cash or restricted cash equivalents. The Company currently presents changes in restricted cash and cash equivalents in the financing section of its statement of cash flows. The new guidance will not impact financial results, but will result in a change in the presentation of restricted cash and restricted cash equivalents within the statement of cash flows. The update to the standard is effective for the Company for periods beginning after December 15, 2017. The Company currently plans to adopt this guidance in the first quarter of 2018 using the retrospective approach. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . The guidance eliminates Step 2 from the goodwill impairment test. In addition, the amendment eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. For public companies, this ASU is effective for fiscal years beginning after December 15, 2019 with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is in the process of evaluating the impact of this ASU on the consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting. ASU 2017-09 provides clarification on when modification accounting should be used for changes to the terms or conditions of a share-based payment award. This ASU does not change the accounting for modifications but clarifies that modification accounting guidance should only be applied if there is a change to the value, vesting conditions, or award classification and would not be required if the changes are considered non-substantive. This ASU is effective for interim periods beginning after December 15, 2017 and is required to be applied on a prospective basis. The Company does not expect the adoption of this ASU to have a significant impact on the consolidated financial statements. In August 2017, FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. ASU 2017-12 changes the recognition and presentation requirements of hedge accounting, including: eliminating the requirement to separately measure and report hedge ineffectiveness; and presenting all items that affect earnings in the same income statement line item as the hedged item. The ASU also provides new alternatives for: applying hedge accounting to additional hedging strategies; measuring the hedged item in fair value hedges of interest rate risk; reducing the cost and complexity of applying hedge accounting by easing the requirements for effectiveness testing, hedge documentation and application of the critical terms match method; and reducing the risk of material error correction if a company applies the shortcut method inappropriately. This ASU is effective for interim periods beginning after December 15, 2018. The Company is in the process of evaluating the impact of this ASU on the consolidated financial statements. Note 1—Description of the Business and Significant Accounting Policies (continued) In September 2017, the FASB issued ASU 2017-13, Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842) which provides additional implementation guidance on the previously issued ASU 2016-02 Leases (Topic 842) . ASU 2016-02 requires a lessee to recognize assets and liabilities on the balance sheet for leases with lease terms greater than 12 months. ASU 2016-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, and early adoption is permitted. The Company is in the process of evaluating the impact of this ASU on the consolidated financial statements. |
