We currently manage US$ 13.6 billion in assets and are focused on investment strategies across private equity, private credit, impact investing and real estate. By combining deep local reach, a global platform and underwriting standards, with extensive operating capabilities, we generate industry-leading returns and create value in market-leading companies. We have a dedicated team of operating professionals who work hand-in-hand with investment teams to actively drive value creation in partner companies, helping them institutionalize and grow. Environmental, social and governance (ESG) factors are deeply embedded in our investment process, a proven value driver in our partner companies. Responsible investing that enhances financial returns is at the core of our philosophy.
