Please expand your revenue recognition policy to disclose the nature of your transportation services, including any performance obligations to arrange for another party to transfer goods or services. Please also include significant payment terms pursuant to ASC 606-10-50-12. 2.

Kevin Stout Landstar System, Inc. August 8, 2018 Page 2 freight; thus, transportation revenue and related freight expenses are recognized on a gross basis from BCO Independent Contracts and Truck Brokerage Carriers, railroad intermodal services and air and ocean services. It appears upon adoption of ASC 606 you continue to recognize revenue on a gross basis from the majority of, if not all, the transactions where a third party is involved in the transportation of freight to a customer. In this regard, please tell us your consideration of the principal agent guidance under the new standard, including the nature of your performance obligation(s) with respect to freight delivery. Your response should include your assessment of control over each service(s) (i.e. BCO Independent Contracts and Truck Brokerage Carriers, railroad intermodal services and air and ocean services) that is transferred to a customer. Where a contract with a customer involves more than one mode of transportation, please identify and describe the nature of the performance obligation(s) and its recognition under ASC 606. Please be detailed in your response to us. Refer to ASC 606-10-25-25 and 606-10-55-36 through 40. 3. We note from your disclosure in footnote 12 that the adoption of the new standard changed the timing of revenue recognition for most of your transportation business from at delivery to over the transit period as the performance obligation is completed. Please tell us the average transit period to complete a shipment. Pursuant to ASC 606-10-50-18, please discuss the method(s) used to recognize your revenue over the transit period, such as a description of the output or input methods and how those methods are applied, in addition to why the methods used provide a faithful depiction of the transfer of goods or services. In closing, we remind you that the company and its management are responsible for the accuracy and adequacy of their disclosures, notwithstanding any review, comments, action or absence of action by the staff.
