Ulster Rugby CEO Shane Logan has announced his intention to stand down from the role this August.
Ulster and the IRFU will begin a recruitment process to ensure a smooth succession. In the meantime, Mr Logan has agreed to continue the day-to-day running of the business until his departure.
Logan said that after eight years in the post he felt the time was right to move on.
"I am very grateful to have had the privilege of being Chief Executive of Ulster Rugby since 2010," he said.
"We have been able to build a fine stadium, repay our debts, deliver consistent profit and strong commercial growth.
"This is now allowing us to invest in our clubs, schools and very significantly in our Academy."
"In terms of win ratios, the senior Ulster Team has become more competitive but I am as disappointed as anybody not to have landed that elusive trophy.
"There have been some significant challenges in recent years. I hope that the unity with which everyone in Ulster faced these will endure for generations. I wish everyone in Ulster the very best for the future."
Philip Browne, IRFU CEO, thanked Shane for his dedication and wished him well in his future ventures.
"Having strong, financially secure provinces is vital to Irish Rugby, and Shane has worked with teams, managers, sponsors, government and other sports effectively over eight years at Ulster Rugby," he said.
"We thank Shane for his dedication to Ulster Rugby and are sorry to see him go, but wish him all the very best for the future."
