The Pension Protection Fund (PPF) is among investors in a 拢500m (鈧567m) infrastructure bond investment in the UK led by Allianz Global Investors.

The 32-year bond relates to the recent acquisition of the M6 toll road in England by infrastructure fund manager IFM Investors.

The M6, the UK鈥檚 only toll motorway, was sold by a group of lenders that took control of the asset in 2013 from Macquarie. 

Allianz Global Investors said it is investing on behalf of a number of Allianz Group companies and third-party clients, through both separate accounts and a UK pooled fund.

The investment means its UK infrastructure debt fund is now fully invested. It plans to launch a second vehicle.

It is also the first time that the 拢23.4bn PPF has invested in infrastructure debt alongside Allianz Global Investors.

Adrian Jones, portfolio manager at Allianz Global Investors, said: 鈥淭he M6 toll road, an essential infrastructure asset with a long operating history, represents exactly the sort of asset our clients look to invest in.鈥

He added: 鈥淭his transaction is particularly noteworthy for Allianz Global Investors as it represents the culmination of over a year鈥檚 work by a large number of our team working from both Paris and London.

鈥淚t is our largest UK investment to date and it completes the investment phase of Fund 1.鈥
