Ulster Rugby's chief executive Michael Reid is stepping down after 12 years in the top role at Ravenhill.
Reid joined the Ulster Branch in the early days of rugby professionalism and initially guided them through some difficult times.
"I am greatly fulfilled by the career I have had at the helm of the Ulster Branch," said Reid.
"But I feel the time is now right for me to step down and pursue other interests."
He added: "We have achieved a great deal in establishing a successful Ulster rugby brand, have enjoyed Celtic and European success on the pitch, and the game generally across the province is in a healthy state," said Reid.
"I wish to thank the officers and committees of the Branch and the Union for the opportunity to hold this position and for their support over the years."
