As a stable, yielding real asset, it delivers returns to investors whilst positively addressing the long-term climate risk which is present in all asset classes… Stafford’s approach to accessing the asset class through secondaries is compelling, accessing assets that otherwise do not come to market and delivering a portfolio that is well diversified by geography, species and age class.”
Stephen Addicott, partner at Stafford Capital Partners, said: “SIT X has been a really successful fundraising for Stafford. Over the course of this fundraising period, we have witnessed the growing consolidation of the asset class as a strategic investment and climate solution for institutional investors… The scale of the fund, combined with our experience in complex secondary transactions allows us to offer investors access to well-established, high-quality timberland portfolios while maintaining attractive risk-adjusted returns.”
Stafford has committed over $330m to five investments in SIT X, covering 27 timberland assets across 1m hectares, with a $140m deal pending.
