| Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
| Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | Organization and Basis of Presentation A. Organization The Company is a Bermuda exempted company and wholly owned subsidiary of Triton formed on September 29, 2015. On November 9, 2015, Triton and TAL jointly announced that they had entered into the Transaction Agreement, pursuant to which Triton and TAL will, upon the terms and subject to the conditions set forth therein, combine in a stock-for-stock, merger of equals transaction. This transaction, which has been unanimously approved by each of the boards of directors of Triton and TAL, is expected to create the world’s largest lessor of intermodal freight containers. The Company has filed a Registration Statement on Form S-4 (Registration No. 333-208757), which was declared effective by the Securities and Exchange Commission (the “SEC”) on May 9, 2016 (as amended, the “Registration Statement”). The Company has not commenced operations, has no significant assets or liabilities and has not conducted any material activities, other than those incidental to its formation and those undertaken in connection with the transactions contemplated by the Transaction Agreement, as may be amended from time to time. Upon the terms and subject to the conditions set forth in the Transaction Agreement, Triton and TAL will combine under the Company, which is and will continue to be domiciled in Bermuda. Company common shares are expected to be listed on the New York Stock Exchange. Upon the terms and subject to the conditions set forth in the Transaction Agreement, former Triton shareholders will own approximately 55% of the equity of the Company and former TAL shareholders will own approximately 45% upon the consummation of the Mergers. Upon the consummation of the Mergers, the Company, through its subsidiaries, will lease intermodal transportation equipment, primarily maritime containers, and provide maritime container management services through a worldwide network of offices, third-party depots and other facilities. The Company will, upon the consummation of the Mergers, operate in both international and U.S. markets. It is expected that the majority of the Company’s business will be derived from leasing its containers to shipping line customers through a variety of long-term and short-term contractual lease arrangements. The Company will also, upon the consummation of the Mergers, sell its own containers and containers purchased from third parties for resale. B. Basis of Presentation The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the reported amounts of revenues and expenses during the reporting period and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Net loss is equal to comprehensive loss. |
