Since fiscal 2019, we executed under a plan to capture certain synergies and cost savings related to streamlining our global operations and sales organization, as well as rationalize certain leased properties that were not fully occupied. Our plan is aligned with our strategy to integrate the global sales organization and further outsource manufacturing functions in order to drive operational efficiency, increase supplier geographic diversity, and reduce operating expenses. To date, total restructuring charges were $17.9 million, comprised of $11.1 million in severance and employee related costs, and $6.8 million for vacant office and manufacturing facility space as well as terminated tower infrastructure leases. Restructuring charges related to vacant office and manufacturing facility space were attributable primarily to the vacancy in Canton, Massachusetts in the amount of $3.3 million. The anticipated rent payments for the ceased-use leased facilities will be made through December 2025. Substantially all charges related to severance and employee costs were under the Telematics Products reportable segment.
