Norway's sovereign wealth fund, Norges Bank Investment Management (NBIM) part of the Norwegian Central Bank, is reported to be "by far the largest in the world" and it's not happy with declining returns on its investment. Companies, it says, are granting salary and bonus packages that deplete companies' resources and promote short-termism in management. It says that C level executives should be properly remunerated but that dashing the cash isn't the way to do it.
