Significant events
- “On 28 February 2026, Israel and the United States launched a military offensive in the Middle East against Iran. This geopolitical event has caused global market disruption, with heightened uncertainty surrounding the potential short- and medium-term implications for investment markets.”
- “Two of the Members have entered into Sale and Purchase Agreement in respect of a potential sale of their interest in the Partnership's sole portfolio asset, while the third Member is at an advanced stage of negotiating a Sale and Purchase Agreement relating to its interest in the same portfolio asset. Completion of these transactions (collectively the 'asset sale transaction') would result in the Partnership entering into liquidation and returning capital to the Members.”
