Oregon Public Employees Retirement Fund (OPERF) is seeking to boost its infrastructure exposure by investing in Global Infrastructure Partners’ latest mega-fund and awarding a separate account to Westbourne Capital.

The pension fund is committing $400m (€345m) to Global Infrastructure Partners IV and is giving Westbourne Capital $230m to invest in infrastructure debt, according to a board meeting report.

Global Infrastructure Partners is currently raising capital for its largest fund yet, seeking between $17.5bn and $20bn. According to OPERF, the company is planning to hold a first close this month.

The pension fund noted that the fund will focus on large and complex transactions, attracting less competition and providing more opportunities to create value.

Westbourne Capital, headquartered in Melbourne, Australia, specialises in investing in infrastructure debt across global markets and sectors. The company did not respond to a request for comment.
