Gosh you can put up some misleading spin - its not a time of his choosing. The term of his contract will expire and he won't be getting it renewed.
He'd be leaving now if it was a time of his choosing.
A more accurate summary is that his performance is not up to scratch and so therefore ABC Board has exercised its discretion and has chosen not to issue an extended contract. He had the hand out earlier this year asking for the contract to be extended but was told then to get stuffed.
