On August 18, 2020, Landstar entered into an amended and restated credit agreement with a syndicate of banks and JPMorgan Chase Bank, N.A., as administrative agent (the “Credit Agreement”). The Credit Agreement, which matures on August 18, 2023, provides $250,000,000 of borrowing capacity in the form of a revolving credit facility, $35,000,000 of which may be utilized in the form of letters of credit. The Credit Agreement includes an “accordion” feature providing for a possible increase up to an aggregate borrowing capacity of $400,000,000.
The Credit Agreement contains a number of covenants that limit, among other things, the incurrence of additional indebtedness. The Company is required to, among other things, maintain a minimum Fixed Charge Coverage Ratio, as defined in the Credit Agreement, and maintain a Leverage Ratio, as defined in the Credit Agreement, below a specified maximum. The Credit Agreement provides for a restriction on cash dividends and other distributions to stockholders on the Company’s capital stock to the extent there is a default under the Credit Agreement. In addition, the Credit Agreement under certain circumstances limits the amount of such cash dividends and other distributions to stockholders to the extent that, after giving effect to any payment made to effect such cash dividend or other distribution, the Leverage Ratio would exceed 2.5 to 1 on a pro forma basis as of the end of the Company’s most recently completed fiscal quarter. The Credit Agreement provides for an event of default in the event that, among other things, a person or group acquires 35% or more of the outstanding capital stock of the Company or obtains power to elect a majority of the Company’s directors or the directors cease to consist of a majority of Continuing Directors, as defined in the Credit Agreement. None of these covenants are presently considered by management to be materially restrictive to the Company’s operations, capital resources or liquidity. The Company is currently in compliance with all of the debt covenants under the Credit Agreement.
