Announcing this on the sidelines of a send-off for some staff on Friday, Commissioner-General Kofi Nti said the targets will be appraised on a quarterly basis.

He said in 2017, the Authority achieved 92 per cent of its revenue target, ending the year with GH¢32.4 billion out of a target of GH¢33.6 billion.

According to him, that was the best performance in five years.

Friday’s send-off saw some 138 non-management staff of GRA being honoured.
