Description of the Business, Basis of Presentation and Recently Adopted Accounting Pronouncements [Text Block] | Note 1—Description of the Business 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 June 30, 2017 , the consolidated statements of operations and comprehensive income for the three and six months ended June 30, 2017 and 2016 , and the consolidated statement of cash flows for the six months ended June 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 June 30, 2017 and its consolidated results of operations and comprehensive income for the three and six months ended June 30, 2017 and 2016 , and the consolidated statement of cash flows for the six months ended June 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 six months ended June 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 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 (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 . As of June 30, 2017 , the Company has gained control or negotiated the release of 92% of our containers previously leased to Hanjin of which approximately 70% are leased to other customers or 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 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 deductible limits in connection with the Hanjin bankruptcy. The insurance policies did not cover its pre-default receivables. The Company has negotiated a $45 million advance partial payment from its insurance providers, of which $44.5 million has been collected. The Company currently believes the anticipated losses as a result of Hanjin will be recoverable under the insurance policies, subject to the 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 June 30, 2016 Six months ended June 30, 2016 Total leasing revenues $ 271,653 $ 553,279 Net income attributable to shareholders $ 4,925 $ 12,373 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 15% of the Company's lease billings during the six months ended June 30, 2017 . Note 1—Description of the Business (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 six months ended June 30, 2017 since no equity awards have vested in those periods. 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 its 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. Earlier application is permitted. The Company is currently evaluating the transition method that will be elected and the potential effects of adopting the provisions of this ASU. 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 adoption of this ASU is not expected to have a material impact on its consolidated financial statements. 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 expects the impact of adoption of this ASU to have a minimal effect on the presentation in the consolidated financial statements. Note 1—Description of the Business (continued) In October 2016, 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 is evaluating the effect the guidance will have 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 update to the standard is effective for the Company for periods beginning after December 15, 2017. The Company is evaluating the effect the guidance will have on its consolidated financial statements. 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 pronouncement, and does not expect it have a significant impact on the consolidated financial statements. In May 2017, 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. The effective date is interim periods beginning after December 15, 2017. The Company is in the process of evaluating the impact of this ASU and does not expect it to have a significant impact on the consolidated financial statements. |
