Fuel surcharge revenues were $133.9 million, $173.8 million, and $169.2 million for the twelve months ended December 31, 2024, 2023, and 2022, respectively. As a result of the CFI acquisition we acquired outsourcing of certain loads to third-party carriers in the U.S. and Mexico. During the twelve months ended December 31, 2024 the Company only outsourced certain loads to third-party carriers in Mexico. The Company is a principal in these arrangements resulting in revenue associated with these contracts being recorded on a gross basis. The primary responsibility to meet the customer's requirements is maintained by the Company as the party performing billing, collection and pricing negotiations with the customer. The Company is also responsible for selecting third-party transportation providers that satisfy our premium customer service requirements. Accessorial, brokerage and other revenues recorded in the consolidated statements of comprehensive income collectively represented $78.0 million, $94.8 million, and $50.7 million for the twelve months ended December 31, 2024, 2023, and 2022, respectively. Included in the accessorial, brokerage and other revenues is $31.8 million of logistics revenue within Mexico for the twelve months ended December 31, 2024. We have property and equipment in Mexico in support of these operations with a net book value of $1.0 million as of December 31, 2024, which are the company's only foreign long-lived assets.
