Summary
Brookfield Asset Management has been selected by the UK's Nuclear Liabilities Fund to manage a distinctive long-term investment mandate valued at $1 billion in initial capital commitments. The mandate was awarded on September 8, 2026, and represents a multi-decade partnership structured to address the fund's primary objective of accumulating sufficient resources to cover the decommissioning costs of eight UK nuclear power stations without requiring additional taxpayer support.
The investment mandate will be executed by Brookfield's Investment Solutions Group (ISG), a specialized division within the firm that constructs customized portfolios for institutional investors. Howard Marks, Co-Chairman of Oaktree, chairs the ISG, while Alper Daglioglu serves as the group's lead. The portfolio will deploy capital globally across Brookfield's core investment strategies, including infrastructure, energy, private equity, real estate, and private credit. Investment vehicles will encompass fund commitments, direct investments, and co-investments, providing diversification across asset classes and geographies.
The structural design of the mandate reflects the unique characteristics of the Nuclear Liabilities Fund's obligations. Rather than pursuing immediate cash distributions, the portfolio is configured to reinvest capital and compound returns over an extended investment horizon. This approach directly aligns with the NLF's multi-decade funding requirements for nuclear decommissioning activities. To date, the fund has already expended approximately £3 billion on decommissioning costs, and the new mandate aims to ensure that remaining liabilities can be met through disciplined, long-term capital appreciation rather than short-term liquidity management.
The Nuclear Liabilities Fund, established in 1996, operates with a clear mandate to invest assets responsibly in pursuit of its long-term objectives. This mandate award demonstrates institutional confidence in Brookfield's capability to manage substantial capital pools with extended time horizons and specialized risk-return requirements. For alternative asset managers, the engagement underscores growing demand from public-sector and institutional entities seeking customized solutions that accommodate liabilities extending decades into the future, while maintaining the flexibility to navigate diverse market conditions across multiple asset classes.
