HDMGlobal is an international consortium of academic and consultancy companies that have formed a partnership for the future management of HDM 4. This was initially a five-year concession awarded by PIARC commencing June 2005 with exclusive rights for its distribution. Following the worldwide success of HDM-4 Version 2 during this period, in June 2010, and again in 2015, PIARC extended this for a further five years. In December 2019, the concession was extended by a further year to the end of July 2021, and subsequently to July 2022, and to July 2024. In April 2024 the concession was again extended to the end of December 2024.
