Subsequent Events	Subsequent Events On February 17, 2015, the board of directors of the Company declared a cash dividend of $0.40 per share of common stock of the Company to shareholders of record as of March 20, 2015 that will be paid on March 26, 2015. In January 2015, LLIII completed a private placement of $625.5 million in aggregate principal amount of notes consisting of $250.0 million in aggregate principal amount of its 2.98% Fixed Rate Secured Railcar Equipment Notes, Class A-1 (Class A-1 Notes) and $375.5 million in aggregate principal amount of its 4.06% Fixed Rate Secured Railcar Equipment Notes, Class A-2 (Class A-2 Notes, and collectively with the Class A-1 Notes, the Notes). The Notes have a legal final maturity date of January 17, 2045 and an expected principal repayment date of January 15, 2025. The Notes are obligations of LLIII only and are secured by, among other things, a portfolio of railcars and leases thereon acquired by LLIII pursuant to a contribution and sale agreement between LLIII and the Company. Additionally, in connection with the Notes offering, LLIII entered into a railcar management agreement with ARL, as manager, under which ARL will manage, operate, market, store, lease, re-lease, sublease and service the subject railcars on behalf of LLIII. This agreement extends at least through the Notes' final maturity date of January 17, 2045. The Notes are not registered under the Securities Act of 1933, as amended (Securities Act), or any state securities laws, and were offered only to qualified institutional buyers in reliance on Rule 144A under the Securities Act and outside the United States in accordance with Regulation S under the Securities Act. The Notes were issued pursuant to an Indenture, dated January 29, 2015 between LLIII and U.S. Bank National Association, as indenture trustee (Indenture Trustee). The Class A-1 Notes bear interest at a fixed rate of 2.98% per annum, and the Class A-2 Notes bear interest at a fixed rate of 4.06% per annum. Interest on the Notes is payable monthly on the 15th calendar day of each month in accordance with the flow of funds provisions described in the Indenture. While the legal final maturity date of the Notes is January 17, 2045, cash flows from LLIII's assets will be applied, pursuant to the flow of funds provisions of the Indenture, so as to achieve monthly targeted principal balances. If the cash flow assumptions used in determining the targeted balances are met, it is anticipated that the Notes will be repaid well in advance of their stated legal final maturity date. There can be no assurance, however, that such cash flow assumptions will be realized. Also, under the flow of funds provisions of the Indenture, early amortization of the Notes may be required in certain circumstances. If the Notes are not repaid by the expected principal repayment date on January 15, 2025, additional interest shall accrue at a rate of 5.0% per annum and be payable monthly according to the flow of funds. LLIII can prepay or redeem the Class A-1 Notes, in whole or in part, on any payment date and the Class A-2 Notes, in whole or in part, on any payment date occurring on or after January 16, 2018. The Indenture contains covenants which limit, among other things, LLIII's ability to incur additional indebtedness or encumbrances on its assets, pay dividends or make distributions, make certain investments, perform its business other than specified activities, enter into certain types of transactions with its affiliates, and sell assets or consolidate or merge with or into other companies. These covenants are subject to a number of exceptions and qualifications. The Indenture also contains certain customary events of default, including among others, failure to pay amounts when due after applicable grace periods, failure to comply with certain covenants and agreements, and certain events of bankruptcy or insolvency. Certain events of default under the Indenture will make the outstanding principal balance and accrued interest on the Notes, together with all amounts then due and owing to the noteholders, immediately due and payable without further action. For other events of default, the Indenture Trustee, acting at the direction of a majority of the noteholders, may declare the principal of and accrued interest on all Notes then outstanding to be due and payable immediately. LLIII has used the net proceeds from the sale of the Notes to purchase railcars from the Company pursuant to a contribution and sale agreement between the Company and LLIII. The Company has used and intends to use the proceeds from the sale of railcars to LLIII for general corporate purposes and to repay certain indebtedness, including two prior lease fleet financings.
