The BBC says that, in September 2014, only ten of its senior managers were paid at or above the market rate for the job. 238 were paid at a discount to other comparable employees greater than the targets set by the BBC. One unidentified executive director was paid less than 20% what he or she might have achieved elsewhere.
It says executives are paid no more than 50% of the salary in comparable organisations; those on the SM1 grade are discounted by a minimum of 30% against the benchmarking of other organisations and companies; and those on SM2 grade are at least 20% against the wider benchmark.
