(1) Reimbursable expenses are costs incurred in the delivery of services to the Company's clients that the client has agreed to reimburse, including media, sample, retailer fees and other marketing and production costs. (2) The “other segment items” category primarily consists of costs incurred in the execution of service obligations, including supplies, technology, and other direct expenses such as travel and indirect general and administrative expenses such as professional fees. These costs align with the segment-level information regularly provided to the CODM and represent the difference between revenue and the significant expense categories above in determining segment profitability.
