Because legal compliance with compensation-related regulations is the responsibility of the compensation department

Because the compensation professional has a fiduciary responsibility to ensure that the financial resources of their organization are spent in a prudent manner

Because it is possible to pay significantly less for talent in different countries and compensation should advise management on when and where to locate various jobs within the company

They shouldn’t. Due to the complexities of global regulations and practices, compensation administration outside of the home country should be outsourced.
