Amortization of streaming content assets makes up the majority of cost of revenues. Expenses associated with the acquisition, licensing and production of streaming content (such as payroll and related personnel expenses, costs associated with obtaining rights to music included in our content, overall deals with talent, miscellaneous production-related costs and participations and residuals), streaming delivery costs and other operations costs make up the remainder of cost of revenues." This is extracted from Netflix's annual report. I am required to translate this into Chinese, but I am not sure what "participations and residuals" means. So could someone translate this term into Chinese?
